If you're shipping goods across an international border, a regular invoice usually isn't enough on its own — customs authorities need a commercial invoice, a specific document built to support the customs clearance process rather than just requesting payment.
What a commercial invoice is for
Where a regular invoice's job is getting you paid, a commercial invoice's job is telling customs officials exactly what's crossing the border, so they can assess duties, taxes, and confirm the shipment is legal to import. It often travels with the shipment itself, attached to the package or held by the carrier, rather than going only to the buyer's accounts-payable department.
What it needs that a regular invoice usually doesn't
- Country of origin for the goods — where they were manufactured, not shipped from.
- Harmonized System (HS) codes, the standardized classification customs uses to determine duty rates.
- Detailed, specific item descriptions — "electronics" isn't sufficient; customs needs enough detail to classify and assess the goods correctly.
- Weight and dimensions, often per item as well as total.
- Incoterms (like FOB, CIF, DDP) clarifying who's responsible for shipping costs, insurance, and risk at each stage of transit.
- Reason for export — sold, gifted, returned for repair — since duty treatment can differ.
Who typically needs one
Any business regularly shipping physical goods internationally — even in small volumes — will need commercial invoices as standard practice. It's less relevant for services, digital goods, or domestic-only shipping, none of which cross a customs border.
Getting the details wrong has real consequences
An inaccurate or incomplete commercial invoice is one of the most common causes of shipments held at customs — sometimes for days, occasionally leading to fines or the shipment being returned. Unlike an ordinary invoice, where a minor error might just mean a follow-up email, an error here can hold up the physical goods.
It doesn't replace your invoice
A commercial invoice supports customs clearance — it doesn't replace the regular invoice you send for payment. Many businesses use the same document for both purposes by including the additional customs fields directly on their standard invoice; others keep them separate. Either approach works as long as the required customs information is present when the shipment crosses the border.
