How to write a commercial invoice that clears customs the first time
The commercial invoice is the document customs actually reads. Get these fields right and most clearance delays never happen.

Of all the paperwork that travels with an international shipment, the commercial invoice does the most work. Customs officers use it to decide what the goods are, what they are worth, where they were made, and how much duty is owed. When a shipment is held at the border, the cause is usually something on — or missing from — this one document.
It is not the same as the invoice you send a customer for payment. A sales invoice can say "Order #4471, 1 × Widget." A commercial invoice must describe the goods precisely enough for a stranger in another country to classify and value them without asking you.
The fields customs expects
- Exporter and importer — full legal names, addresses, and contact details for both parties. Include tax or registration numbers where the destination requires them.
- Consignee, if different from the buyer — the party physically receiving the goods.
- Invoice number and date.
- A specific description of each item — what it is, what it is made of, and what it is for.
- HS code for each line, so the goods can be classified for duty.
- Quantity and unit of measure — pieces, kilograms, litres, pairs.
- Unit value and total value, with the currency stated.
- Country of origin — where the goods were manufactured, not where they ship from.
- Incoterm and named place, which tells customs what the stated value includes.
- Reason for export — sale, sample, repair and return, gift, or temporary import.
- Gross and net weight, and the number of packages.
- A signed declaration that the information is true and correct.
Descriptions are where shipments stall
Vague wording is the single most common reason a shipment gets held for questions. Customs officers cannot classify "parts," "samples," "accessories" or "gifts" — so they stop the shipment and ask.
| Will be queried | Will clear |
|---|---|
| Parts | Stainless steel hex bolts, M8 × 40 mm, for industrial machinery |
| Clothing | Men's knitted pullover sweaters, 100% cotton |
| Electronics | Wireless Bluetooth headphones with lithium-ion battery, contained in equipment |
| Samples | Unpriced fabric swatches, 100% polyester, 20 × 20 cm, no commercial value |
| Gift | Ceramic coffee mugs, set of four, personal gift, used |
Value it honestly — including the "free" items
Customs duty is calculated on declared value, and every country treats under-declaration as a serious offence. Penalties can include fines, seizure of the goods, and a record that leads to closer inspection of every future shipment.
Items with no commercial value still need one. Samples, replacements under warranty and gifts must carry a fair market value — what the item would sell for — with a note such as "No charge — replacement under warranty, value for customs purposes only." Declaring "$0" will almost always cause a hold.
A final check before it goes
- Every line has a description a stranger could classify.
- Every line has an HS code and a country of origin.
- Values are in a stated currency and add up to the total.
- No item is declared at zero.
- The Incoterm is stated with a named place.
- Piece count and weight match the packing list and waybill.
- The declaration is signed and dated.
- You have attached copies in the number the destination requires — typically three.
Requirements differ by destination: some countries require invoices in a particular language, some want a certificate of origin alongside it, and some need specific statements for preferential duty under a trade agreement. When shipping somewhere for the first time, check the destination's rules before the goods leave.
