BIS HALLMARKING HUID (GOLD & SILVER) SETUP & REGISTRATION SERVICES

INTRODUCTION

BIS Hallmarking is a crucial requirement for ensuring purity, quality, and transparency in gold and silver jewellery. With the introduction of the mandatory 6-digit HUID (Hallmark Unique Identification), jewellers must strictly follow BIS norms to operate legally and build customer trust.

With the mandatory implementation of the 6-digit HUID (Hallmark Unique Identification) system, adherence to BIS hallmarking requirements has become essential for jewellers. BIS hallmarking reflects authenticity, quality assurance, and consumer confidence in precious metal jewellery.

AN Global Services offer comprehensive support for the establishment of Silver Hallmarking HUID Centre as well as BIS Jeweller Registration, ensuring compliance with the latest standards and guidelines issued by the Bureau of Indian Standards.

Our services cover the complete process, including facility planning, technical setup, documentation, coordination for inspections, and licensing assistance, helping your jewellery business remain compliant, transparent, and operationally efficient.

Gold Hallmarking HUID Centre Setup

GOLD HALLMARKING HUID PROCESS

In 2026, gold hallmarking in India continues with the mandatory HUID (Hallmark Unique Identification) system, providing a digital identity for every piece of gold jewelry. The HUID ensures transparency, traceability, and consumer protection by linking each hallmarked article to a central BIS database.

THE GOLD HALLMARKING HUID MARKS:

A hallmarked gold article consists of exactly three marks laser-engraved on the item:

BIS Logo: The standard triangular mark of the Bureau of Indian Standards.

Purity Grade: Indicates the gold fineness (e.g., 916 for 22 Karat).

HUID Code: A unique 6-digit alphanumeric code (e.g., AB1234).

The HUID Process (Step-by-Step)

1. Registration

The jeweler must be registered with BIS and possess a valid BIS license.

2. Submission

The jeweler submits gold articles to a BIS-recognized Assaying and Hallmarking Centre (AHC).

3. Sampling & Testing

The AHC takes a sample from the jewelry to test purity using X-ray Fluorescence (XRF) or Fire Assay methods.

4. HUID Generation

Once purity is confirmed, the AHC logs into the BIS portal and the system generates a unique 6-digit HUID for each piece.

5. Laser Engraving

The BIS logo, purity grade, and unique HUID are laser-marked on the article.

6. Digital Record

All details (jeweler name, purity, weight, date) are stored in the central BIS database.

PURITY GRADES FOR GOLD

Under current BIS standards, gold is hallmarked in the following specific grades:

995

Mandatory Equipment for Gold Hallmarking HUID Centre Setup

A Gold Hallmarking HUID Centre must be equipped with BIS-compliant testing, marking, and assaying infrastructure. While BIS does not mandate specific brands, all equipment must meet the prescribed technical accuracy, performance, and safety requirements as per applicable Indian Standards.

Equipment	Critical Technical Specifications (BIS 2026)
XRF Gold Testing System	Must be equipped with a Silicon Drift Detector (SDD). Capable of detecting Cadmium (Cd), Lead (Pb), Iridium (Ir), and Ruthenium (Ru). Accuracy requirement: ±0.01% for non-destructive purity analysis and fraud detection.
Fiber Laser Marking Machine	Laser power range: 20W–50W; wavelength: 1064 nm; marking speed: 7000–8000 mm/s. Must support automated engraving of the 6-digit HUID, BIS logo, and gold purity mark.
Cupellation Furnace	Uniform heating capability up to 1150°C. Must include controlled air inlet and outlet systems to support lead oxidation during the fire assay process.
Annealing Furnace	Uniform heating capability up to 750°C, used for softening gold samples prior to rolling and further chemical analysis.
Melting Furnace	Uniform heating capability up to 1200°C (or higher as required). Must be equipped with precise temperature control and even heat distribution to ensure complete and consistent melting of samples.
Micro / Semi-Micro Balances	5-decimal (semi-micro) or 6-decimal (micro) analytical balances with a minimum capacity of 500 g, used for high-precision weighing of gold samples before and after assaying.

Compliance Note: All equipment must be regularly calibrated and supported by valid calibration certificates traceable to recognized standards. Documentation must be available during BIS audits, surveillance inspections, and proficiency testing.

CHARGES FOR THE GOLD HALLMARKING

Gold hallmarking charges for Assaying and Hallmarking Centres (AHCs) are standardized to ensure uniformity and transparency across all recognized centres. Charges are applied on a per-article basis, with applicable minimum batch and testing fees, and all billing must be supported by a GST invoice with corresponding HUID details for traceability.
