What is a BIS HUID Code? How to Verify Gold Purity in 2026 | PMJ GOLD

If you have bought or inherited gold in India recently, you have likely heard the term HUID code. BIS hallmarking is no longer just a fancy stamp—it is mandatory consumer protection. But what does that tiny 6-digit alphanumeric code actually guarantee when you hold a piece of jewellery or a coin in your hand? Here is your complete guide to reading BIS hallmarks.

The 3 Visible Symbols on Every Genuine Gold Item

  1. BIS Logo: The triangular mark of the Bureau of Indian Standards certifying that the metal meets national standards.
  2. Purity & Fineness Mark: A clear indicator of metal purity (e.g., 22K916 for 22 Karat 91.6% purity, or 24K999 for 24 Karat 99.9% investment coins).
  3. 6-Digit Alphanumeric HUID: A unique Hallmarking Unique ID stamped on every individual piece. No two items in India share the same HUID.

How to Verify Your Gold Using the BIS CARE App

  • Step 1: Download the official BIS CARE app on your Android or iOS device.
  • Step 2: Navigate to the "Verify HUID" feature on the home screen.
  • Step 3: Type in the 6-digit code stamped on your jewellery or coin assay card.
  • Step 4: Instantly view the registered jeweller’s name, hallmarking center details, item type, and exact tested karat purity.
Rule of thumb: If a seller offers you a "discount" to buy gold without a hallmark or HUID stamp, you are not saving money—you are buying unverified metal that will cost you heavily at sell-back.

Ever wondered why the price quoted on live gold rate tracking apps is so different from the final invoice given at traditional jewellery counters? The answer lies in two terms: making charges and wastage (tunch). Understanding how these fees are calculated can save you thousands of rupees on every purchase or exchange.

Deconstructing Your Gold Bill: The 4 Core Components

Component What It Means Standard Industry Range
Live Bullion Rate Pure metal cost based on current market rate per gram Transparent / Market-linked
Making Charges Craftsmanship fee charged per gram or as a % of gold cost 8% to 35% (0% to 3% for coins)
Wastage % Gold lost during melting, shaping, and soldering Should be merged into making charges
GST (3%) Mandatory government taxation applied on (Gold + Making) Fixed 3% nationwide

How to Prevent Overpaying for Gold

  1. Separate metal value from labor cost: Always insist on an itemized bill that explicitly separates the daily gold rate from the craftsmanship fee.
  2. Buy 24K coins for savings: Coins carry near-zero wastage compared to intricate bridal bangles or stone-studded necklaces.
  3. Ask for net weight vs gross weight: Never pay the gold rate per gram for heavy enamel work, lacquer fillings (lacc), or non-precious beads.
Rule of thumb: Making charges are a cost of wearability, not investment. When buying pure wealth, choose low-making 24K bullion coins over high-making designer jewellery.

When selling gold or exchanging family heirloom pieces, lack of transparency can cost sellers anywhere between 10% and 30% of their asset's real value. Unscrupulous dealers count on customer hesitation and complex math to quietly deduct value. Here are the top 4 gold-buying traps and how to protect yourself.

The 4 Most Common Gold Buying Traps

  • The High Rate Bait-and-Switch: Advertising an artificially high rate per gram on banners, but applying huge undisclosed "melting deductions" or "service fees" at the final weighing scale.
  • Inaccurate Scales (The Touch Test Trap): Using uncalibrated digital balances or weighing ornaments on soft surfaces that skew the exact grammage downwards.
  • Behind-the-Wall Testing: Taking your jewellery into a backroom or basement out of sight to test or melt it without your direct supervision.
  • Acid Scrapes: Deeply scratching your ornament against a stone before agreeing on a binding price quote, damaging your piece permanently even if you decide not to sell.

Your Rights as a Gold Seller

  1. Right to non-destructive testing: Insist on XRF Karatmeter testing that measures gold purity in front of your eyes without scraping or acid.
  2. Right to zero-obligation quotes: Get a complete printed breakdown of rate, weight, purity, and net payout *before* giving consent to melt or process anything.
  3. Right to instant electronic payment: Receive payouts directly to your savings bank account via UPI/IMPS for a clean, traceable financial record.
Rule of thumb: Never let your gold leave your direct line of sight during evaluation. A legitimate buyer tests transparently right on the counter.
