BIS Hallmark & GST Invoice Checklist for Bulk Corporate Gold Coin Purchases
Sun Sea Jewellers, Karol Bagh, New Delhi · 12 August 2026
When a corporate gift turns out to be underweight or below the stated purity, it's your company's name attached to that gift, not just the supplier's. This is a short, practical checklist for what to actually verify before a bulk order — not a sales pitch, a due-diligence list.
1. Ask for the BIS Hallmark, Not Just "Certified"
"Certified" on its own means nothing specific. Ask explicitly for BIS hallmarking with a HUID (Hallmark Unique Identification) number on each coin. A legitimate supplier can explain exactly what purity that hallmark represents (999, 995, 916, etc.) without hesitation.
2. Get the Purity and Weight in Writing, Per Unit
Not just a total order weight — ask for per-coin weight and purity stated on the invoice itself. If a supplier is reluctant to itemise this, treat it as a red flag, not an inconvenience they're saving you from.
3. Confirm the GST Rate and HSN Code
Gold and silver coins fall under HSN 7118 and should be taxed at a flat 3% GST on the full invoice value (typically split 1.5% CGST + 1.5% SGST for intra-state purchases). If a quote shows a different rate without explanation, ask why before paying.
4. Understand What You Can (and Can't) Claim Back
Input Tax Credit is generally blocked on gifts under Section 17(5) of the CGST Act — coins distributed as unconditional gifts typically don't qualify for ITC. Don't assume you can claim it back without checking with your own GST consultant first; this is a genuine area where assumptions cost companies money at year-end reconciliation.
5. Ask About Return/Buyback Policy — Before You Need It
If an order is over-produced, under-ordered, or a batch has an issue, what's the supplier's policy? Get this in writing before the order is placed, not after something goes wrong.
6. Verify Turnaround Time in Writing, With a Buffer
Custom logo-engraved coins typically take 7–12 working days after design approval. Ask for a written delivery date, not just a range — and build in a few days' buffer given festive-season production queues fill up fast.
Quick FAQ
What does BIS hallmark actually guarantee?
It guarantees the stated gold or silver purity has been independently verified — not the design, not the weight of stones if any are set, just the metal purity itself.
Do we need a separate certificate beyond the invoice?
A proper GST invoice stating weight, purity, and rate per gram, plus the BIS hallmark on the coin itself, is sufficient for most corporate purposes — you generally don't need a separate lab certificate for coins the way you might for a cut diamond.
Can we claim GST input tax credit on gifted coins?
Generally no, under Section 17(5) of the CGST Act for unconditional gifts — confirm your specific situation with a GST consultant, since conditional/incentive-linked distribution has seen different treatment in some rulings.
