Everything global sellers need to know about commercial invoices. Learn required customs fields, HS tariff codes, Incoterms, and declaration statements.
What Makes a Commercial Invoice Different from a Standard Invoice?
A standard invoice serves as a payment request between a buyer and a seller. A commercial invoice, by contrast, is a legal customs declaration required for cross-border freight and parcel shipments. Customs border agencies use it to assess import duties, tariffs, and cargo eligibility.
7 Mandatory Fields on Every Commercial Invoice
- Harmonized System (HS) Tariff Code: A 6-to-10 digit standard international classification code identifying the product category.
- Country of Origin: Where the goods were manufactured or assembled, not just where they shipped from.
- Incoterms (International Commercial Terms): 3-letter trading terms (e.g., FOB, DDP, CIF, EXW) specifying who pays shipping, insurance, and duties.
- Detailed Itemized Goods Description: Clear description of materials, components, and intended usage (avoid vague terms like "samples" or "parts").
- Unit Value & Extended Value: Clear valuation in the specified trading currency (e.g., USD, EUR, GBP).
- Gross & Net Weight: Total package weight including pallet/packaging and net weight of goods.
- Shipper's Declaration & Authorized Signature: Formal statement certifying that invoice figures represent true market transaction value.
