A commercial invoice is the document that travels with exported goods and tells customs what is being shipped, what it is worth and who is responsible for it.
Quick answer: A commercial invoice declares exported goods to customs: seller and buyer (exporter/importer), a specific description per line, quantity, value, currency, country of origin, HS codes and the incoterm. Carriers typically require three signed copies.
Fields customs looks for
Exporter and importer with full addresses
Per-line description specific enough to classify
Country of origin (where manufactured)
HS / tariff code per line
Value and currency of sale
Incoterm (who pays duties/freight)
Reason for export (sale, sample, warranty replacement)
Why descriptions get shipments stuck
'Samples' or 'spare parts' are the top reasons parcels sit in customs. '2× cotton T-shirts, 180 gsm, HS 6109.10' clears. Describe like a customs officer would classify.
Copies and signing
Standard practice: three signed copies — one in a documents pouch, two in a pouch on the box. Carriers may provide a pouch; the generator's printout is accepted by all major carriers.
Frequently Asked Questions
Is a commercial invoice the same as a sales invoice?
No. The sales invoice is for accounting; the commercial invoice is for customs. They often share amounts but the commercial one adds origin, HS codes and incoterms.
Do I need a commercial invoice for documents?
Pure documents usually ship without one, but carriers may still ask for a declaration stating 'documents only, no commercial value'.
Who signs a commercial invoice?
The exporter or their agent. An unsigned invoice can be rejected at clearance.
