The Hallmarking Unique ID (HUID) is now the cornerstone of India's gold jewellery compliance framework. Introduced by the Bureau of Indian Standards, every piece of hallmarked gold jewellery sold in India must carry a 6-character alpha-numeric HUID — a unique code that permanently links that specific article to its test and assay record. As of 2026, selling gold jewellery without HUID-based hallmarking is a legal violation with serious consequences for jewellers.
What is HUID? Understanding the Basics
HUID stands for Hallmarking Unique Identification. It is a 6-digit alpha-numeric code assigned to each individual piece of jewellery when it is hallmarked at a BIS-licensed Assaying and Hallmarking Centre (AHC). No two pieces of jewellery can have the same HUID — it is issued sequentially and permanently recorded in the BIS digital portal.
A HUID-hallmarked article carries four marks: (1) the BIS logo, (2) the purity/fineness mark (e.g. 916 for 22K gold), (3) the AHC identification mark, and (4) the 6-character HUID.
Why HUID Matters for Indian Jewellers in 2026
Legal Compliance
Since September 2021, HUID-based hallmarking has been mandatory for gold jewellery sold in 288 notified districts. By 2026, the mandate has been extended progressively across India. Selling non-hallmarked or non-HUID jewellery now attracts penalties under the BIS Act 2016 — fines of up to ₹1 lakh or five times the value of the jewellery (whichever is higher), plus potential imprisonment.
Consumer Protection and Trust
Consumers can verify the purity of any HUID-hallmarked piece using the BIS Care app. This traceability builds lasting trust — and jewellers who comply report measurably higher repeat purchases and referrals from transparency-conscious buyers.
E-Commerce Compliance
Major e-commerce platforms — Amazon, Flipkart, Myntra — require HUID details at the product listing stage. Without a valid HUID, gold jewellery listings are rejected or delisted. Jewellers expanding to online channels must be HUID-compliant to participate.
Export Eligibility
Several international buyers, particularly in the UAE, UK, and US, now prefer or require HUID-hallmarked gold. Indian HUID hallmarking is internationally recognised as a mark of purity and quality assurance.
How the Hallmarking Process Works: Step by Step
Step 1 — Register as a Jeweller with BIS
Every jeweller must register on the BIS portal as a certified jeweller before they can send articles for hallmarking. Registration is online. BMS assists jewellers with the registration process, document submission, and portal navigation.
Step 2 — Submit Articles to a BIS-Licensed AHC
The jeweller submits gold articles to the nearest BIS-licensed Assaying and Hallmarking Centre (AHC). The AHC assays the purity of each article using XRF (X-Ray Fluorescence) or fire assay methods.
Step 3 — Assay and HUID Assignment
The AHC tests the gold purity and assigns a unique HUID to each passing article. This HUID is registered in the BIS digital portal against that specific piece, that specific jeweller, and that specific AHC.
Step 4 — Hallmarking and Return
The hallmarking marks — BIS logo, purity, AHC mark, and HUID — are laser-engraved or stamped on the article. The hallmarked jewellery is returned to the jeweller, ready for sale.
Step 5 — Ongoing Record-Keeping
BIS conducts random market surveillance. Jewellers must maintain records of every HUID article sold — buyer name, contact, date of sale, and HUID — for a minimum of 2 years. Digital records are preferred and increasingly mandatory.
Documents Required for BIS Jeweller Registration
- GST Registration Certificate
- PAN Card of the proprietor / company
- Shop and Establishment Certificate or Trade Licence
- Udyam Registration Certificate (for MSME units)
- Cancelled cheque or bank account proof (for fee payment)
- Photograph of the business premises (exterior and interior)
- Address proof of the business premises
- Aadhaar Card of the proprietor or authorised signatory
- Email ID and mobile number (OTP-verified for portal registration)
Common HUID Compliance Mistakes Jewellers Make
Selling Old Stock Without HUID
Old jewellery stock manufactured before HUID became mandatory can still be sold, but it must first go through an AHC for assay and HUID assignment. Selling pre-HUID stock as-is is a violation.
Using Unregistered AHCs
Not all assaying centres are BIS-licensed. Hallmarking done at an unlicensed centre has no legal standing. Always verify that your AHC appears in the BIS's official AHC list.
Inadequate Sales Records
BIS market surveillance officers regularly check jeweller records. Inability to produce a sale register linked to HUID data is treated as a compliance failure. Digital record-keeping — even a simple spreadsheet — is strongly recommended.
Penalties for Non-Compliance in 2026
- Sale of non-hallmarked gold jewellery: fine up to ₹1 lakh or 5× article value
- Misuse of hallmarking marks: fine up to ₹2 lakh + potential imprisonment
- Refusal to allow BIS inspection: prosecution under BIS Act 2016
- Repeat offences: enhanced penalties and potential licence cancellation
