The BIS Hallmark is a hallmarking system for gold as well as silver jewellery sold in India, certifying the purity of the metal.[1][2] It certifies that the piece of jewellery conforms to a set of standards laid by the Bureau of Indian Standards, the national standards organization of India. India is the second biggest market for gold and its jewellery.

India imports in excess of 1000 tons annually (including unofficially smuggled gold) with negligible local production.[3] The annual gold imports are around 50 billion US$ next only to crude oil imports widening the trade deficit.[4]

Gold

[edit]

The BIS system of hallmarking of gold jewellery began in April 2000. The standard specifications governing this system are IS 1417 (grades of gold and gold alloys, jewellery/artefacts), IS 1418 (assaying of gold in gold bullion, gold alloys and gold jewellery/artefacts), IS 2790 (guidelines for manufacture of 14, 18 and 22 carat gold alloys only ), IS 3095 (gold solders for use in manufacture of jewellery).[5]

The BIS hallmark is a standardized certification system managed by the (BIS), the national standards body of , designed to accurately determine and officially record the purity of precious metals such as and silver in jewelry, artifacts, , and coins. Introduced to protect consumers from adulteration and ensure compliance with Indian Standards (IS) for metal fineness, the system involves testing at recognized Assaying and Hallmarking Centres, followed by the application of official marks that include the BIS logo, purity notation (e.g., 22K916 for 22-carat ), and a unique six-digit alphanumeric Hallmark Unique Identification (HUID) code for traceability. Hallmarking in India traces its origins to recommendations by the Reserve Bank of India in the late 1990s, with BIS launching the voluntary scheme for gold in 2000 and extending it to silver in 2005, governed by standards like IS 1417 for gold and IS 2112 for silver. The process requires jewelers to register with BIS—free and valid for life—before submitting items to accredited centres for fire assay or other approved methods to verify metal content against specified caratage levels, such as 9, 14, 18, 22, or 24 for gold. This certification not only assures buyers of authenticity but also enhances India's position in the global gold market by promoting export-quality standards and reducing malpractices. Mandatory hallmarking for gold jewelry and artifacts (in 14, 18, and 22 carats) was enforced starting June 2021 in phases across districts, expanding to 373 districts by August 2025 and including 9-carat gold from July 2025, with exemptions for small jewelers below ₹40 lakh annual turnover and certain artisanal items. For silver, voluntary HUID-based hallmarking was introduced nationwide from September 1, 2025, under updated IS 2112:2025, which specifies seven purity grades including 800, 835, 925, 958, 970, 990, and 999, requiring the HUID system for silver articles to align with gold protocols and further safeguard consumer interests, with mandatory status under evaluation. As of late 2025, over 1,000 recognized centres operate across India, supporting more than 194,000 registered jewellers in this regulated ecosystem.

Introduction

Definition and Purpose

The BIS hallmark is an official marking administered by the (BIS) that certifies the purity of and silver in jewelry and artifacts through standardized testing and stamping, ensuring the accurate determination and official recording of the proportionate content of precious metals in these articles. This involves assaying the metal content at recognized centers to verify compliance with established fineness standards. The primary purpose of the BIS hallmark is to safeguard consumers from adulteration and malpractices related to purity, thereby obligating manufacturers and jewelers to adhere to legal standards of . It provides verifiable indicators of purity, such as caratage for and millesimal for both and silver, which foster consumer confidence by enabling informed purchasing decisions. Additionally, the scheme aligns Indian practices with international hallmarking norms, enhancing export competitiveness and positioning as a prominent global center for and silver trade. The scope of BIS hallmarking encompasses jewelry, artifacts, and coins made of and silver sold within , covering items from various levels without specifying individual grades. As a mechanism under the BIS certification scheme, it originated as a voluntary program in 2000 but has transitioned to mandatory implementation in designated districts to broaden protection and standardization. Recent updates include the extension of mandatory hallmarking to 9-carat from July 2025. This evolution draws briefly from longstanding global hallmarking traditions aimed at assuring metal purity in commerce.

Historical Background

The practice of hallmarking precious metals traces its origins to ancient civilizations, where markings were used to certify the purity and quality of and silver artifacts. The practice of hallmarking precious metals traces its origins to ancient civilizations, such as , , and , where markings were used to indicate quality and origin. In medieval , particularly in from the 14th century, guild-based assaying offices formalized hallmarking under royal charters to combat fraud, establishing standards that evolved into modern systems. In , traditional quality assurance for precious metals relied on informal assays conducted by artisan guilds known as shrenis, dating back to the later , where goldsmiths and merchants self-regulated purity through community oversight without a centralized standard. These guilds, prominent in ancient trade hubs like and , ensured trust in transactions but lacked uniformity, leading to inconsistencies until colonial influences introduced rudimentary standardization in the . The absence of a national system persisted post-independence, highlighting the need for a formalized framework to protect consumers amid growing jewelry markets. The modern BIS hallmarking system was launched voluntarily for gold jewelry in April 2000 by the (BIS), following recommendations from a 1999 government committee that identified BIS as the sole agency to certify purity under Indian Standard IS 1417, aiming to standardize assays across the country. This initiative began with a phased rollout of assaying and hallmarking centers, starting in major cities like , , and , expanding gradually to approximately 375 centers by the mid-2010s to accommodate regional jewelers. Voluntary hallmarking for silver was introduced in October 2005 under IS 2112, extending the scheme to silver jewelry and artifacts with similar purity certification processes. The BIS Act of 2016 marked a pivotal shift by empowering the government to enforce hallmarking as mandatory, replacing the earlier voluntary framework under the 1986 Act and integrating measures like penalties for non-compliance. Recent advancements include the Hallmark Unique ID (HUID) system for , implemented from June 2021 to enable digital traceability of each piece via a unique six-digit code, with mandatory adoption by April 2023. This was extended to silver in September 2025, introducing voluntary HUID-based hallmarking to enhance verification and combat adulteration.

Hallmarking Standards

For Gold

The Bureau of Indian Standards (BIS) establishes specific purity standards for gold under its hallmarking system to ensure consumer protection and quality assurance in jewelry and artifacts. These standards define the minimum fineness levels for various caratages, expressed in millesimal fineness (parts per thousand), which indicate the proportion of pure gold in the alloy. BIS recognizes several caratages suitable for hallmarking, focusing on those commonly used in Indian jewelry making. As of November 2025, following Amendment No. 2 to IS 1417:2016 in July 2025, eligible caratages include 9K (375 fineness, equivalent to 37.5% pure gold), 14K (585 fineness, 58.5% pure gold), 18K (750 fineness, 75% pure gold), 20K (833 fineness, 83.3% pure gold), 22K (916 fineness, 91.6% pure gold), 23K (958 fineness, 95.8% pure gold), and 24K (999 fineness, 99.9% pure gold). These levels allow for durability in lower caratages while maintaining high purity in higher ones, with 22K being the most prevalent for traditional Indian ornaments due to its balance of malleability and value. Higher purities like 23K are permitted for specific artifacts, such as temple donations or ceremonial items, where near-pure gold is required for cultural or religious purposes. Gold below 9K fineness is not eligible for BIS hallmarking, as it falls outside the recognized standards for jewelry and artifacts; similarly, scrap gold or unprocessed forms are excluded from the scheme. These purity requirements are governed by the Indian Standard IS 1417:2016, titled "Gold and ," which has been amended over time to incorporate additional caratages and refine marking protocols, including the addition of 9K in July 2025 for mandatory hallmarking of articles over 2 grams. The standard mandates that hallmarked must meet or exceed the specified , with tolerances applied during testing to account for variations. For instance:
CaratageMillesimal FinenessPercentage Purity
9K37537.5%
14K58558.5%
18K75075.0%
20K83383.3%
22K91691.6%
23K95895.8%
24K99999.9%
This table summarizes the key grades, emphasizing their practical application in the industry. To verify gold fineness, BIS-approved Assaying and Hallmarking Centres employ standardized testing methods, primarily fire assay for destructive and (XRF) for non-destructive verification. Fire assay, detailed in IS 1418:2009, involves melting the sample with fluxes to separate , providing high accuracy (within 0.02%) suitable for confirmation of purity in jewelry. XRF, a faster surface-level scan, is used for preliminary checks without altering the item, ensuring efficiency in routine hallmarking. These methods are integrated into an automated process at recognized centres to maintain consistency and traceability. Mandatory hallmarking, initially for 14K, 18K, and 22K from 2021, has been expanded to all recognized caratages including 9K, 20K, 23K, and 24K as of 2025, covering articles over 2 grams and enhancing transparency across the market.

For Silver

The (BIS) establishes purity standards for silver hallmarking under the revised Indian Standard IS 2112:2025, which specifies seven grades based on millesimal : 800 (80% pure silver), 835 (83.5%), 925 (92.5%), 958 (95.8%), 970 (97%), 990 (99%), and 999 (99.9%). These grades replace the previous six under IS 2112:2014 and introduce 958 and 999 to accommodate higher-purity options, with all expressed as parts per thousand to denote silver content. This standard applies to a range of silver articles, including , utensils (such as silverware), and artifacts, ensuring consistent quality across consumer products. Unlike hallmarking, which uses a carat system for purity measurement, silver relies solely on notation for its benchmarks. The 2025 update integrates Hallmarking Unique Identification (HUID), a six-digit alphanumeric code for each piece, enabling digital traceability via the BIS Care app to verify authenticity and prevent counterfeiting. Testing for silver purity in BIS hallmarking follows methods similar to those for , primarily involving assay for precise or non-destructive techniques like (XRF) spectrometry, with traditional used for preliminary checks. The recommended professional method to verify silver coin purity is to take the coins to a BIS-recognized assaying and hallmarking center for accurate testing using methods like fire assay or XRF. Acid testing is common but may scratch the surface. Some refineries, such as Bangalore Refinery Pvt Ltd (BRPL), recommend cross-checking at BIS-recognized centers and do not endorse handheld karat meters due to their unreliability. , denoted as 925 , serves as the most common benchmark due to its balance of durability and purity in everyday and items. Hallmarking is not permitted for silver below 800 , though the standard encompasses decorative items and coins as qualifying artifacts when they meet or exceed this threshold. Implementation began with a voluntary phase on September 1, 2025, aligning silver processes with gold's digital framework; as of November 2025, it remains voluntary, though mandatory enforcement is anticipated within six months to broaden consumer protection. This rollout enhances market transparency, particularly for high-value items like 999 fine silver coins and ornate utensils.

The Hallmarking Process

Steps in Hallmarking

The hallmarking process under the (BIS) follows a structured sequence to certify the purity of and silver jewelry, ensuring compliance with established quality norms through registered jewelers and recognized centers. Jewelry manufacturers or sellers must first register as jewelers with BIS via the online portal at no cost, receiving a lifetime registration number that enables them to submit items for hallmarking. Once registered, the jeweler selects a BIS-recognized Assaying and Hallmarking Centre (AHC) from the list available on the BIS website to handle the testing. The jeweler then submits batches of jewelry of similar design and declared purity to the chosen AHC, often via an request that logs the details digitally for tracking. Upon receipt, the AHC verifies the submission against the jeweler's registration and segregates the batch for processing. At the AHC, testing commences with random sampling from the batch, where representative samples are selected as per IS 15820 for analysis. Purity is assayed using established techniques, including non-destructive (XRF) spectrometry for initial screening or the more precise fire assay method for gold and silver fineness verification, ensuring the metal content aligns with BIS specifications. If the batch passes the , the AHC approves it and applies the hallmark via , incorporating the unique Hallmark Unique Identification (HUID) code—a six-digit alphanumeric identifier—for individual . HUID generation became mandatory for jewelry in 2021 and was introduced voluntarily for silver in 2025. In case of failure, the batch is rejected, with the AHC providing documented reasons to the jeweler, who may address issues for resubmission. AHCs maintain comprehensive records of each step, including results and HUID assignments, uploaded to the BIS portal to support ongoing traceability and audits.

Components of the BIS Hallmark

The BIS hallmark is composed of distinct elements that collectively certify the purity and origin of and silver jewelry, with variations depending on the metal and implementation date. These components are laser-etched onto the article to provide verifiable information without altering its appearance significantly. The Standard Mark serves as the primary indicator of certification, featuring an iconic triangular logo originally displaying "ISI" (Indian Standards Institute) but updated to the modern logo, signifying compliance with (BIS) quality norms for precious metals. This mark confirms that the jewelry has undergone testing and meets the relevant Indian Standards, such as IS 1417 for or IS 2112 for silver. The purity indicator specifies the metal's fineness, expressed differently for and silver to denote composition. For , it uses caratage followed by a three-digit fineness number, such as 916 for 22 karat (91.6% pure ) or 750 for 18 karat (75% pure ), aligning with standardized grades under IS 1417:2016. For silver, it indicates fineness directly, like 925 for (92.5% pure) or 999 for fine silver (99.9% pure), as per IS 2112:2025. This element allows consumers to quickly assess value and authenticity. Prior to 2021, the jeweler's identification mark was a unique code or symbol registered with BIS, identifying the manufacturer or seller responsible for the piece. Similarly, the assaying centre code was a numeric or alphanumeric identifier for the BIS-recognized testing facility that performed the purity . These were essential for but have since been integrated into the HUID system for streamlined verification. The Hallmark Unique Identification (HUID) is a six-digit alphanumeric introduced in July 2021 for and extended voluntarily to silver from September 2025, enabling digital traceability by encoding details like the jeweler, assaying centre, purity, and date of hallmarking. Users can scan or enter the HUID via the official BIS Care app or website to retrieve full records, enhancing consumer trust and combating counterfeiting. An optional year code may be included, providing additional context on the item's age. Placement of these components is typically laser-etched in a discreet location, such as inside the jewelry article (e.g., on the inner surface of rings or bangles) or on attached tags for larger pieces, ensuring durability and minimal visibility while allowing easy inspection with . These elements together facilitate comprehensive throughout the .

Infrastructure and Implementation

Assaying and Hallmarking Centres

Assaying and Hallmarking Centres (AHCs) serve as independent facilities recognized by the (BIS) to perform purity testing, hallmark stamping, and quality control for and silver jewellery and artefacts in . These centres function as specialized laboratories that ensure compliance with BIS purity standards, such as IS 1417 for and IS 2112 for silver, by analyzing samples for metal content and certifying only those meeting the required fineness levels. Equipped with advanced analytical tools like (XRF) spectrometers, fire furnaces, and marking machines, AHCs conduct non-destructive and methods to determine precise metal purity. Operations typically involve receiving batches of from BIS-registered jewellers, performing assays on representative samples, and, upon approval, stamping the items with the BIS hallmark including the centre's identification number. Centres maintain strict adherence to BIS protocols, including equipment calibration, sample handling procedures, and record-keeping, with daily capacities ranging from 50 to 500 pieces depending on facility scale and levels. As of November 2024, over 1,600 BIS-recognized AHCs are operational nationwide, reflecting significant growth from earlier years to meet rising demand under the mandatory hallmarking scheme. These centres are predominantly located in key jewellery production and trade hubs, including (with over 300 facilities), , , and , which account for a substantial share of India's organized jewellery sector. Post the 2021 expansion of mandatory hallmarking—and further extensions including the fifth phase adding 12 districts in August 2025 to reach 373 districts—BIS has facilitated outreach to tier-2 cities like , , and , extending coverage and reducing regional disparities in access. The inclusion of 9-carat gold hallmarking from July 2025 has also increased demand on these facilities. Quality assurance is upheld through periodic on-site audits by BIS officials, who evaluate testing accuracy, operational hygiene, and procedural integrity at least annually. Recognition as an AHC is valid for three years, requiring renewal via a comprehensive assessment that includes proficiency testing and verification to sustain operational standards. Technological integration has been a key focus, with AHCs adopting BIS-mandated online portals for generating Hallmark Unique ID (HUID) codes—alphanumeric identifiers unique to each hallmarked item—and enabling real-time upload of test data for . This system allows for digital verification by consumers via the BIS Care app or portal, linking the HUID to details of the , jeweller, and centre, thereby enhancing transparency and preventing counterfeiting.

Registration and Accreditation

Jewellers seeking to participate in the BIS hallmarking scheme must register online through the official BIS portal at www.manakonline.in under the Hallmarking tab, providing essential business details such as trade name, address, contact information, and PAN for verification. This mandatory registration ensures compliance with standards, requiring jewellers to commit to selling only hallmarked gold and silver , cooperating with BIS activities, and utilizing recognized Assaying and Hallmarking Centres (AHCs) exclusively. The process is free of charge, with instant approval upon submission, granting a unique Registration Number via or and a downloadable certificate. Registration enables jewellers to access nearby AHCs for hallmarking services. As of November 2024, over 1.94 jewellers had registered under the scheme, reflecting significant industry adoption. For AHCs, accreditation involves a rigorous recognition managed by BIS, where applicants submit an online application to the relevant regional BIS office, accompanied by a self-certified quality manual, affidavits, and proof of setup. Key requirements include adequate facilities such as separate chambers for reception, (XRF) analysis, sampling, , and laser engraving; trained staff, with the Assay In-charge holding a or degree plus specialized training; and calibrated equipment traceable to national standards, verified through NABL-accredited laboratories. BIS conducts on-site assessments lasting up to four man-days to confirm adherence to IS 15820 standards, granting recognition upon successful verification. As of late 2024, over 1,600 AHCs had been recognized nationwide, supporting expanded hallmarking capacity. Renewal for jeweller registration is not periodically required, as the certificate remains valid for a lifetime, though jewellers must apply online for endorsements in case of changes like address or ownership and maintain ongoing compliance through annual surveillance by BIS. In contrast, AHC recognition must be renewed every three years via the BIS online portal, involving submission of updated documents and fees, followed by a surveillance audit within 60 days to ensure continued adherence to operational standards. Non-compliance during audits, such as equipment malfunctions or purity deviations exceeding 5 parts per thousand, can lead to suspension or cancellation of recognition. To facilitate participation, BIS offers training programs for jewellers and AHC staff on compliance and operations, while industry bodies like the Gems and Jewellery Export Promotion Council (GJEPC) conduct webinars and seminars to address hallmarking implementation. Additionally, digital tools such as the BIS Care App and the Manakonline portal enable real-time tracking of registrations, hallmarking records, and compliance status, enhancing transparency and ease of adherence.

Mandatory Hallmarking Timeline

The Bureau of Indian Standards (BIS) introduced voluntary hallmarking for gold jewellery and artefacts in April 2000 to promote consumer trust in metal purity. This scheme operated on an optional basis until the government issued the Hallmarking of Gold Jewellery and Gold Artefacts Order, 2020, on January 15, 2020, under the BIS Act, 2016, initially set to enforce mandatory hallmarking from January 15, 2021. Due to disruptions from the COVID-19 pandemic, implementation was deferred, with the first phase launching on June 16, 2021, requiring hallmarking for 14-karat, 18-karat, and 22-karat gold in 256 districts across India. The second phase expanded coverage to an additional 32 districts on April 4, 2022, while the third phase added 55 more districts starting September 8, 2023. Subsequent phases continued this rollout, with the fourth phase incorporating 18 districts from November 5, 2024, bringing the total to 361 districts, and the fifth phase adding 12 more districts effective July 31, 2025, reaching 373 districts. From June 1, 2022, mandatory hallmarking extended to additional gold purities of 20-karat, 23-karat, and 24-karat in covered areas; hallmarking for 9-karat gold became mandatory from July 2025. For silver, BIS established voluntary hallmarking in October 2005 under IS 2112 standards to certify purity at fineness grades of 800, 835, 925, 958, 970, 990, or 999. This remained optional until the revision to IS 2112:2025, which introduced Hallmarking Unique Identification (HUID) for enhanced traceability; mandatory enforcement for silver and artefacts began nationwide on September 1, 2025, aligning with the updated standard. The mandatory rollout prioritized the organized jewellery sector, with jewellers required to register with BIS and use only hallmarked items for retail sales in implemented districts. Exemptions apply to articles intended for , or silver used in dental alloys, and small-scale production by artisans, including jewellery under 2 grams per piece; additionally, jewellers with annual turnover below ₹40 are exempt from registration but may voluntarily comply. These measures, notified under the BIS Act, 2016, and the 2020 Order with subsequent amendments, accommodate industry challenges while extending protections. Mandatory hallmarking covers all domestic retail sales of new and silver jewellery and artefacts in , excluding second-hand, , or collectible items to preserve their historical value. As of November 2025, the scheme covers 373 districts (out of approximately 766 in ), with over 40 items hallmarked since 2021, reflecting progressive regulatory evolution.

Enforcement and Penalties

The enforcement of BIS hallmarking regulations is primarily conducted by officers of the (BIS), who are empowered under of the BIS Act, 2016, to carry out inspections, searches, and seizures of non-compliant jewellery articles suspected of violating hallmarking provisions. These activities include surprise raids on units, retail outlets, and assaying centres to detect unauthorised use of the BIS hallmark or sale of non-hallmarked and silver items, as demonstrated in operations such as the July 2025 raid in where 1.072 kg of non-hallmarked gold was seized. Consumer forums established under the , also play a role in addressing complaints related to substandard or misrepresented hallmarked products, providing a platform for redressal beyond BIS-led actions. Compliance with hallmarking mandates is monitored through random sampling of at retail points, where samples are tested for purity at recognised assaying centres to verify adherence to Indian Standards. Verification of hallmark authenticity is facilitated by the Hallmark Unique Identification (HUID) system, a six-digit alphanumeric code that consumers and enforcers can scan using the BIS Care or online portal to cross-check details against the central database maintained by BIS. This digital tracking mechanism enables real-time detection of fake or mismatched hallmarks, reducing instances of adulteration in the . Penalties for violations of hallmarking requirements under the BIS Act, 2016, are stipulated in Section 29(2) for contraventions of Section 14, which mandates hallmarking for notified precious metal articles; these include imprisonment for up to one year, or a fine not less than ₹1 lakh and up to five times the value of the goods, or both. For repeat offenses involving misuse of the standard mark under Section 17, penalties escalate under Section 29(3) to imprisonment up to two years, a minimum fine of ₹2 lakh for the first offense (increasing to ₹5 lakh for subsequent ones), or up to ten times the value of the goods, or both. Additionally, under the Consumer Protection Act, 2019, violators face civil liabilities, including compensation to affected consumers and potential imprisonment up to seven years for misleading practices related to product quality claims. Consumers can report suspected violations, such as fake hallmarks or non-compliant sales, through the BIS online complaint portal at services.india.gov.in or by emailing [email protected], with a dedicated at 1800-11-4000 for prompt assistance. The industry is encouraged to adopt self-regulatory measures, such as voluntary audits by jewellers' associations, to promote compliance and minimise interventions. To address challenges like hallmarks, BIS employs digital tracking via HUID for swift detection, complemented by government-led awareness campaigns, including events on , to educate stakeholders on verification processes. Mandatory hallmarking, which began in phases from June 16, 2021, has been supported by these tools to ensure widespread adherence.

Benefits and Challenges

Consumer Protection

The BIS hallmarking scheme enhances transparency for consumers by providing verifiable assurance of precious metal purity, thereby mitigating risks of fraud such as under-karatage, where sellers misrepresent the gold or silver content in jewelry. Each hallmarked item features a unique Hallmark Unique Identification (HUID) code, a six-digit alphanumeric identifier that links the product to its assaying details, including the certified , jeweler, and hallmarking center. Consumers can scan this code using the official BIS CARE mobile application to instantly verify authenticity and purity online, empowering informed purchasing decisions without relying solely on seller claims. This system further empowers buyers by enabling them to insist on hallmarked products during transactions, as mandatory regulations since June 2021 require jewelers to certify items above specified thresholds. If occurs, consumers have recourse through independent testing at any BIS-recognized Assaying and Hallmarking Centre (AHC), where samples can be assayed for a nominal fee to confirm compliance with Indian Standards. For silver items, including coins, this verification can utilize non-destructive X-ray fluorescence (XRF) testing, available at these centers or many jewelers for a small fee, providing accurate purity assessment without damaging the item. The Bureau of Indian Standards recommends taking such articles to recognized centers for professional testing, as alternative methods like handheld karat meters may be unreliable, while acid testing, though common, can potentially scratch the surface. Legal protections under the Act, 2016, allow filing complaints via the BIS portal, BIS CARE app, or consumer forums, facilitating redressal and potential compensation for substandard goods. Economically, BIS hallmarking safeguards consumers from overpayment by ensuring they receive value commensurate with the certified fineness, eliminating discrepancies that could lead to financial losses from adulterated metals. This promotes fair pricing across the market, as the hallmark's indication of purity (e.g., 22K or 916 ) serves as a benchmark for valuation during resale or melting, reducing disputes and enhancing trust in transactions. Post-2021 mandatory implementation, the government has bolstered consumer awareness through targeted initiatives, including nationwide campaigns by the Ministry of Consumer Affairs and BIS regional offices to educate buyers on hallmark recognition and verification. Jeweler training programs, such as those organized by BIS branches, focus on compliance and ethical selling, while updated labeling requirements mandate clear display of the BIS logo, purity mark, and HUID on all eligible items to facilitate easy identification at .

Industry Impact

The implementation of BIS hallmarking has presented significant adoption challenges for the Indian jewelry industry, particularly for small and medium enterprises (SMEs). Initial costs associated with acquiring assaying machinery and providing staff training have been estimated at 5-7% of for many jewelers, straining operational budgets especially in rural and unorganized sectors. During the 2021 mandatory hallmarking rollout, supply chain disruptions arose due to limited availability of hallmarking centers, leading to production delays and logistical bottlenecks for manufacturers reliant on timely . These hurdles prompted BIS to mitigate concerns by waiving registration fees, which spurred jeweler sign-ups from 36,000 to 40,000 in short order, though smaller operations continued to face procedural adjustments. On the positive side, BIS hallmarking has fostered greater consumer trust, resulting in sales growth for compliant jewelers who leverage the as a differentiator. This shift has enhanced export competitiveness, with the standardized purity marks gaining recognition from international bodies and aligning Indian products with global standards, with India's gems and exports targeting $32 billion in FY2026 as of November 2025. Market dynamics have evolved toward organized retail, where chains now capture 35-40% of the sector, up from lower shares pre-mandate, as hallmarking enforces transparency and that unorganized players struggle to match. For small artisans, transition support includes exemptions for items under 2 grams or businesses with turnover below ₹40 , alongside BIS-conducted workshops to ease compliance without direct subsidies. Economically, the gold jewelry market has grown to approximately ₹7.3 lakh crore ($85 billion) as of early 2025, driven by formalization through hallmarking, with around 65% of recent consumer purchases being certified items—a figure expected to rise toward 80% with broader enforcement. The silver sector, following the introduction of voluntary HUID-based hallmarking from September 1, 2025, with plans for mandatory enforcement in the future, is positioned for parallel growth, formalizing a fragmented market and mirroring gold's trajectory in , requiring the HUID system for silver articles to align with gold protocols, with exemptions for small entities and items as per BIS rules. In October 2025, BIS launched a pilot for digital capture of jewellery details, including photos and weights, at 25 centres to improve verification. Looking ahead, the integration of Hallmark Unique ID (HUID) with digital tools promises to streamline operations by enabling blockchain-like and photo-based verification, reducing counterfeits and operational inefficiencies for manufacturers. BIS's 2025 pilot for digital capture of jewelry details on its portal further enhances transparency, positioning the industry for sustained expansion in both domestic and export markets.
