In import-export activities, the Commercial Invoice (CI) is not only a core document used to request payment but also a critical basis for customs authorities to determine customs value and calculate duties. Even a small mistake on a Commercial Invoice can result in shipment delays, cargo holds, and additional storage costs.
This article will help you clearly understand the mandatory contents of a standard international Commercial Invoice and the “critical” notes to avoid documentation risks.
1. What is a Commercial Invoice?
A Commercial Invoice is a fundamental document in international trade issued by the seller (exporter) to request payment from the buyer (importer) for the goods supplied. Unlike domestic invoices, international Commercial Invoices do not follow a fixed legal format and can be customized by each company, as long as all required information is included.
2. Common Contents of a Commercial Invoice
To ensure validity for customs clearance and international payment, a Commercial Invoice typically includes:
-
Seller (Shipper) & Buyer (Consignee) Information: Full name, address, phone number, email, and tax ID (if applicable), consistent with the sales contract.
-
Invoice Number & Date: Each invoice must have a unique reference number. The issue date is usually on or after the contract signing date and must be before the Bill of Lading (B/L) date.
-
Description of Goods: Product name, specifications, grade/quality, and HS code (very important for duty classification).
-
Quantity & Weight: Unit of measurement (PCS, KGS, MT, etc.), total quantity, net weight, and gross weight.
-
Unit Price & Total Amount: Clearly state the currency used (USD, EUR, VND, etc.).
-
Incoterms (Delivery Terms): Specify the applicable Incoterms version (e.g., FOB, CIF, EXW under Incoterms 2020) and the exact place of delivery.
-
Terms of Payment: Payment method (T/T, L/C, D/P, etc.) and beneficiary bank details.
-
Shipping Information: Vessel/flight number, port of loading, and port of discharge.
3. Mandatory Information on a Commercial Invoice
-
Reference Information: Invoice number, date, seller and buyer details (name, address, contact info, tax ID), contract number and date.
-
Goods Details: Product name, quantity, total quantity, and country of origin.
-
Pricing Information: Unit price per item, currency, all applicable charges paid by the seller → total invoice value.
-
Payment Terms & Delivery Conditions: Payment method and Incoterms.
-
Shipping Details: Mode of transport, port of loading, port of discharge, delivery date, vessel/flight name and number.
-
Signature & Stamp: Authorized signature and company seal (if required).
4. Critical Notes When Preparing a Commercial Invoice
Preparing a Commercial Invoice may seem like a simple copy-paste from the contract, but small errors can lead to major consequences. Key points to pay attention to:
-
Consistency Across Documents: All information must match exactly with the Sales Contract, Packing List, Bill of Lading, and Certificate of Origin (C/O), especially quantity, weight, and product description.
-
Discounts & Additional Charges: Clearly list any discounts or additional charges (packing fees, inland transport, etc.) as separate line items before calculating the final total. Customs will use this to determine taxable value.
-
Signature & Company Seal: While electronic invoices without signatures are widely accepted, some markets or L/C payment requirements still require authorized signatures and company stamps.
-
FOC (Free of Charge) Goods: Even for samples or free goods, the invoice must still declare a value (e.g., “Value for customs purposes only”) for customs duty calculation.
-
Invoice Date: Must be on or before the vessel departure date.
