Lab Diamond Import Guide: HS Codes & Regulations
Importing lab grown diamonds across international borders requires knowing the right customs classification, understanding duty rates, and having the correct documentation. Getting this wrong can mean customs delays, unexpected costs, or even seized shipments.
This guide covers the basics for B2B buyers importing lab grown diamonds into major markets. Note that regulations change — always verify with your local customs authority or a licensed customs broker before placing an order.

1. HS Codes for Lab Grown Diamonds
Lab grown diamonds are classified under HS code 7104 — synthetic or reconstructed precious and semi-precious stones. The specific sub-classifications:
| HS Code | Description |
|---|---|
| 7104.90 | Synthetic precious/semi-precious stones, unworked or simply sawn/cleaved |
| 7104.91 | Diamonds only — unworked or simply sawn, cleaved, or bruted |
Polished lab grown diamonds typically fall under the broader 7104 category. The exact 6-10 digit code varies by country. Your supplier's commercial invoice should state the correct HS code for your destination market.
Important: Lab grown diamonds are NOT classified under HS code 7102 (natural diamonds). Using the wrong code can trigger customs audits and penalties.
2. Kimberley Process: Does It Apply?
No. The Kimberley Process Certification Scheme (KPCS) applies exclusively to rough natural diamonds and is designed to prevent conflict diamonds from entering the legitimate supply chain. Lab grown diamonds — whether rough or polished — are not covered by the Kimberley Process and do not require a KP certificate.
Some customs authorities may still ask about KP status for any diamond shipment. Having a clear statement on the commercial invoice — "Lab grown diamonds, not subject to Kimberley Process" — can prevent unnecessary delays.
3. Required Import Documentation
A standard lab grown diamond import shipment should include:
- Commercial Invoice — with HS code, country of origin, value per stone and total, statement that goods are lab grown/synthetic
- Packing List — itemized list matching the invoice
- IGI/GIA Certificates — one per stone, matching the invoice line items
- Air Waybill — from the carrier (FedEx, DHL, UPS)
- Certificate of Origin — if required by the destination country (some markets require this for preferential duty rates)
4. Duty Rates by Major Market
Customs regulations differ from country to country. Below is a general reference — always check your local tariff schedule before ordering, as rates and requirements can change:
