For Indian importers, the supplier's commercial invoice is just the visible tip of the iceberg; the real cost of goods hides in freight, insurance, duty, and port charges.

If you treat the foreign supplier's invoice value as your 'purchase rate', you will eventually underprice, underpay GST, or both — and either your margins or your CA will scream.

This guide explains how to interpret import invoices and customs documents, calculate landed cost, and translate all of that into clean purchase and sales invoices inside India.

Anatomy of a foreign supplier invoice to India

Most overseas suppliers bill you in foreign currency and mention Incoterms (like FOB, CIF, DAP) that decide who pays for freight, insurance, and risk at each leg.
The invoice will typically show unit price, quantity, total value, HS code (their country's classification), and sometimes country of origin declarations for trade agreements.
For Indian compliance, you still need to map their HS code to the correct Indian HS code and GST rate; never blindly copy their code without checking with your customs broker or CA.
Treat this invoice as one piece of a bundle that also includes packing list, bill of lading/airway bill, and insurance certificates — customs and your bank will look at all of them together.

From CIF value to assessable value: how customs sees your invoice

At the port, customs authorities do not just look at your supplier's invoice value (FOB); they build an 'assessable value' by adding freight, insurance, and specific adjustments.
If your Incoterm already includes freight and insurance (for example, CIF), that value flows straight into assessable value; otherwise, standard percentages or actual amounts may be added.
On top of this assessable value, applicable Basic Customs Duty (BCD), Social Welfare Surcharge, and then IGST on imports are calculated.
The IGST on imports appears on the Bill of Entry, not on your supplier's invoice, but it is crucial — that is what eventually becomes your input tax credit under GST.

Calculating landed cost so your pricing does not lie

Landed cost is the total per-unit cost of getting goods from your supplier's door to your sellable inventory — including product cost, freight, insurance, duty, IGST (net of credit), clearing, and local logistics.
A practical way is to add up all import-related expenses for a shipment (supplier invoice, freight, insurance, customs broker fees, port charges, local transport), then divide by total units received.
Decide how you treat IGST: if you can fully claim it as input credit, it affects cash flow but not long-term cost; if not, you should treat part or all of it as a real cost in your pricing.
Once you know landed cost per unit, bake in your desired margin and GST to arrive at realistic Indian selling prices that survive currency swings and shipping surprises.

Recording import purchases cleanly in your books and GST

In your accounting system, you will usually create one purchase record against the foreign supplier (for the commercial invoice) and one for the customs IGST and duties (based on the Bill of Entry).
The IGST on imports shown in the Bill of Entry flows into your GST returns as input tax credit, so keep these documents mapped to your internal purchase entries.
If you work with an Indian freight forwarder or customs broker, their debit note will often bundle freight, clearance, and port charges; decide which parts are capitalized into inventory and which go to expense.
Tie every sale in India back to a specific batch or shipment when possible; if a batch has higher landed cost due to higher freight, your pricing or discounting strategy should respect that reality.

Common import invoicing traps for Indian MSMEs

Ignoring Incoterms and assuming the foreign supplier's unit price is all-in leads to shock invoices from shipping lines and freight forwarders later.
Not collecting or safely storing Bills of Entry and related customs documents breaks the audit trail for IGST credit and can cause credits to be challenged.
Failing to account for USD/EUR rate movement between proforma invoice, final invoice, and payment date can wipe out your expected margin on thin-spread products.
Using one flat 'purchase rate' in your invoicing or ERP, without revisiting it after each shipment's true landed cost, gradually decouples your books from reality.
