Importing Lab-Grown Diamonds from India: The Documents, Duties and Checks Every Retailer Should Have in Place
The first order is rarely the hard part. A retailer finds a manufacturer, agrees on stones, and then the real questions start. What paperwork comes with the parcel? What will customs ask for? How do I know the stones in the box are the stones on the invoice?
At Nishal Gems we hear these questions from first-time importers almost every week, usually in the days just before they place an order. This guide answers them in the order buyers tend to ask them, so you can walk into your first import knowing what a properly documented shipment looks like.
The short answer
A properly documented lab-grown diamond shipment from India should arrive with a commercial invoice, a packing list, a grading report for each certified stone, an origin declaration, and the shipping and insurance documents for the courier. Each stone's report number should match the laser inscription on the girdle and the line on your invoice. Duties, VAT and any import documentation depend on your country, so confirm those with your customs broker before the parcel ships.
The rest of this guide explains each of those pieces and what to check.
Why this matters more than it used to
India now ships lab-grown diamonds in very large volumes. In March and April 2026, lab-grown stones made up roughly half of India's total diamond export volume, overtaking natural diamonds in those months. That growth means more buyers in more countries are importing for the first time, and customs authorities, banks and insurers are asking more detailed questions than they did a few years ago.
There is also more attention on origin and traceability across the whole diamond trade. From January 1, 2026, the EU requires traceability evidence, including a Due Diligence Statement on Diamond Origin, for polished diamonds that fall within its sanctions-related scope. Many buyers are not sure whether any of this touches lab-grown stones. We cover that below.
Step 1: The documents that should come with every parcel
Think of the paperwork as the parcel's identity. If a document is missing, vague or inconsistent, that is a reason to pause before you pay.
Document | What it does | What to check |
Commercial invoice | Declares what is being sold, to whom, at what value and on what terms | Buyer and seller details, stone description, quantity, total carat weight, value in the agreed currency, Incoterm, payment terms |
Packing list | Lists every stone or lot in the parcel | Stone count and total weight match the invoice, each stone identified by report number or lot code |
Grading reports | Independent description of each certified stone | Report numbers match the invoice and the laser inscription, and the report is marked as lab-grown |
Origin declaration | States where the goods were manufactured | Country of origin, manufacturer details, signed and dated |
Airway bill or courier waybill | Contract with the carrier | Consignee details match your import registration, declared value matches the invoice |
Insurance document | Covers the parcel in transit | Insured value, who is the beneficiary, and what the cover includes |
Export clearance paperwork | Shows the parcel left India lawfully | Your manufacturer handles this, but ask for copies |
Two habits save buyers a lot of trouble. First, ask for the document set in draft before the parcel ships, so you can compare it against your purchase order. Second, keep the documents together for every shipment. Customs, accountants and insurers can all ask for them months later.
Step 2: Getting the HS code right
Customs systems classify goods by Harmonized System code, and the code on your invoice should match what your customs broker expects to see. Lab-grown diamonds are generally classified under heading 7104, which covers synthetic or reconstructed precious and semi-precious stones. Within that heading, the sub-code depends on whether the stones are rough or worked.
Two points to keep in mind:
The code is declared by the exporter and checked by the importing country's customs. A mismatch between the two can delay clearance.
Different countries add their own digits to the international code. Your broker will tell you the full national code for your market.
We suggest asking your manufacturer which code they use on export paperwork, then asking your broker to confirm it works for your import entry. Step 3: Do lab-grown diamonds need Kimberley Process certificates?
This is one of the most common questions we get, and it is easy to get confused.
The Kimberley Process is an international scheme that tracks rough natural diamonds, with the aim of keeping conflict diamonds out of legitimate trade. It was designed for natural diamonds. Lab-grown diamonds are made in a facility, not mined, so they sit outside that scheme.
What buyers should expect for lab-grown stones is different:
A grading report from a recognised laboratory that identifies the stone as laboratory-grown
An origin declaration from the manufacturer
Clear invoice wording that states the stones are lab-grown
If a manufacturer says you need Kimberley Process paperwork for a lab-grown parcel, or tries to skip the lab-grown wording on the invoice, ask why. Clear, consistent disclosure on every document is the standard to look for.
Step 4: Understanding origin and traceability rules
Origin documentation matters for two reasons. Customs may use the country of origin to decide which duty rate applies. And some markets have introduced traceability requirements for diamonds to enforce sanctions.
The EU requirement that began on January 1, 2026 is aimed at natural polished diamonds and the risk of Russian-origin stones entering the market. Lab-grown stones are made in a facility and are generally treated differently from natural diamonds. Even so, buyers sometimes find that their broker, bank or insurer asks for an origin statement on any diamond parcel. The simplest approach is to have a signed origin declaration ready for every shipment, and to ask your broker whether anything further applies to your entry.
Because rules in this area are changing, treat any advice you read online, including this guide, as a starting point and confirm it with your broker or the relevant customs authority before you rely on it.
Step 5: What to expect in the UK, UAE and EU
Every market has its own import process. The points below are general, so please confirm details locally.
United Kingdom
Importers generally need to be registered with HMRC for customs purposes, and import VAT applies at the border. Duty treatment for diamonds and the way shipments are declared are worth confirming with a UK customs agent. Courier shipments often clear through the carrier's own customs service.
United Arab Emirates Dubai is a major trading hub for diamonds, and many importers operate through free zones or established trading licences. The paperwork you need depends on whether the parcel is entering the mainland, a free zone or being re-exported. VAT treatment also differs by situation, so ask your licensed customs agent which route applies.
European Union Import VAT and customs declarations are handled in the member state where the goods enter. The traceability and due diligence rules mentioned above are relevant to the wider diamond trade, so ask your broker how they apply to lab-grown entries. Having a clear origin declaration and consistent invoice wording makes this easier.
Whichever market you buy for, the best preparation is a customs broker who has handled diamond or jewellery parcels before. A specialist will know what the local customs office asks for and can warn you about delays.
Step 6: Choosing shipping terms and insurance
Diamonds are small and high in value, so shipping decisions matter. The Incoterm on your invoice decides who carries the risk and who pays for what at each stage.
Term | In plain language | Where it suits |
FCA or similar | The manufacturer hands the parcel to your carrier, and you take responsibility from there | Buyers who already have a trusted courier and want to control shipping |
CIF or CIP | The manufacturer arranges and pays for transport and insurance to your destination, but risk can pass earlier | Buyers who want a simple quote, provided they understand where risk transfers |
DAP | The manufacturer delivers to your door, and you handle import clearance and duties | Buyers who want delivery arranged but prefer to manage customs themselves |
DDP | The manufacturer handles delivery and import clearance, including duties | First-time buyers who want one all-in arrangement, where available |
Whichever term you choose, confirm three things in writing:
Who insures the parcel and for how much. The insured value should match the invoice value.
Who owns the risk at each stage. This matters if a parcel is delayed or damaged.
Which courier is used. Use insured, tracked carriers that handle valuables, and avoid sending diamonds by ordinary post.
On arrival, ask for the parcel to be opened in front of a witness, or record the opening on video. If something is wrong, you will want evidence of the seal condition and the contents as received.
Step 7: Check the stones before you pay and when they arrive
Paperwork shows what the parcel is supposed to contain. Inspection shows what it actually contains. Both matter.
Before you pay or release the order
Ask for the report numbers and verify each one on the grading laboratory's website, which most major labs allow
Ask for clear photos or video of the stones, with report numbers visible where possible
Confirm in writing that every stone is lab-grown and whether any post-growth treatment has been applied, and that the report reflects this
Agree on tolerance, return and dispute terms before the parcel ships
When the parcel arrives
Count the stones and weigh the parcel against the packing list
Match each stone's report number to the laser inscription on the girdle. A jeweller's loupe with good lighting, or a microscope, will show the inscription
Compare the stone with the report on shape, measurements, colour and clarity. Small differences in measurements are normal, but large gaps need an explanation
Check the stones with an appropriate screening device if you buy mixed parcels, since lab-grown and natural stones can end up together in the wrong hands
Photograph everything and keep the packaging
None of this is meant to make importing sound difficult. Buyers who run through the same short checklist on every order tend to catch problems early and build smoother relationships with their manufacturers.
Step 8: Payment terms that protect both sides
Payment terms vary between manufacturers and between new and repeat buyers. First orders often involve advance or partial advance payment, while repeat customers may agree on credit terms based on history. A few practical points:
Pay against a proper invoice that matches the shipment, and to a bank account in the manufacturer's registered business name
Be careful with any request to pay to a personal account or a different company name
Use traceable bank transfers and keep the confirmations with your shipment file
If the order is large, consider asking about alternatives such as letters of credit, and speak to your bank about what they offer
If payment instructions change suddenly between the quote and the invoice, call the manufacturer on a number you already trust before you send money.
Red flags worth pausing for
Invoices that do not say the stones are lab-grown, or that use vague terms
Report numbers that do not appear on the laboratory's website
No laser inscription on certified stones, or an inscription that does not match the report
Reluctance to share draft documents before shipment
Pressure to pay quickly to a personal or third-party account
Prices far below what comparable certified stones are quoted at, with no explanation
A company that cannot tell you where its stones are grown, cut and polished
Any single point on this list can have an innocent explanation, but several together are a signal to slow down.
Questions to ask any manufacturer before you order
Do you grow, cut and polish the stones yourselves, or are some stages done by partners?
Which grading laboratories do you use, and are the stones laser inscribed?
Can I see the full document set in draft before shipment?
Which HS code and Incoterm will be on the invoice?
Who arranges insurance, and what is the insured value?
What are your return and dispute terms if a stone does not match its report?
What are your minimum order quantities and typical lead times?
Can you provide references from buyers in my country?
A manufacturer that answers these directly, and in writing, is usually one you can build a long-term relationship with.
A short checklist for your first import
Appoint a customs broker with experience in diamonds or jewellery
Confirm your import registration and any local licensing

Final thoughts
Importing lab-grown diamonds from India is routine for the buyers who prepare for it.
The paperwork is not complicated, but it must be complete, consistent and honest. Match the documents to the stones, confirm the rules with a local broker, and agree the terms in writing.
