## Why check gold purity?
Gold buyers should verify purity, check the six-character HUID code using the BIS Care app and examine hallmark details before purchasing jewellery this Dhanteras.
## BIS hallmarking rules
BIS rules require hallmarked gold jewellery to carry three mandatory markings: BIS logo, purity in caratage and fineness, and a six-character alphanumeric HUID code.
## How to check purity?
For example, 22-carat gold is marked 22K916 indicating 91.6% gold content, while 18-carat gold carries 18K750 for 75% gold content.
## Verify HUID code
Download BIS Care app, select 'Verify HUID', enter the six-character code on jewellery to check purity and hallmark details.
## Check jewellery bill
Invoice must list description, net weight, purity in caratage and fineness, hallmarking charges, and final amount payable.
## Compensation for low purity
If gold purity falls short, buyers get twice the difference in weight as compensation plus testing charges.
## Gold coins and bars
BIS hallmarking rules apply to jewellery and artefacts, not gold coins and bars of 999 or 995 fineness.
## Key steps for buyers
Verify BIS hallmark, check HUID code via BIS Care app, and retain detailed invoice to avoid purchasing low purity gold.
## What happens next?
Buyers should check purity, verify HUID code, and retain invoice before purchasing gold jewellery this Dhanteras.
## Key takeaway

Buyers should verify gold purity using BIS hallmark, check six-character HUID code via BIS Care app, and retain invoice for compensation if purity falls short.
