An export shipment is stopped far more often by an incomplete document than by a transport problem. A commercial invoice is not there to get you paid — it is there to clear customs. If it does not contain what customs and the bank expect, the goods sit still even when the truck arrived on time.
What an export invoice must contain
| Element | Why it matters | If missing or vague |
|---|---|---|
| Goods description | Enables tariff classification | Amendment at customs, days lost |
| Tariff code | Determines duty and obligations | Classification challenged, penalties |
| Country of origin | Preferential regimes and trade defence | Full tariff applied |
| Incoterms rule with named place | Allocation of cost and risk | Disputes over who pays what |
| Quantity, net and gross weight | Consistency with packing list and transport document | Documentary discrepancy |
| Value and currency | The basis for assessment | Valuation enquiry |
The description is the critical point. “Spare parts” is not a description: nothing can be classified from it. “Steel ball bearings for industrial pumps” is. Customs cannot guess, and when it cannot guess, it stops the goods.
Consistency across documents
Invoice, packing list and transport document must tell the same story: same consignee, same quantities, same weights, same description. A discrepancy of a few units between invoice and packing list is enough to trigger an inspection.
Under a documentary credit the constraint is tighter still: you write what the credit says, even when you could write it better. Technical precision there is a financial risk — the typical case on shipments to Libya, where a discrepancy blocks the payment, not just the clearance.
Origin: the line that costs most
The country of origin is not the country the goods ship from. Stating the wrong origin, or omitting it, means losing a preferential regime the goods would have qualified for — and the buyer discovers it when paying the full tariff. The relationship between A.TR and EUR.1 turns on exactly this point.
The documents that travel with the invoice
- Packing list itemised per package, with gross and net weights.
- Transport document — CMR, bill of lading or AWB, made out as instructed.
- Certificate of origin or movement certificate, in the form the destination requires.
- Certificate of conformity in markets that impose one, such as Iraq, Saudi Arabia and Nigeria.
- Dangerous goods declaration with UN number, class and packing group where applicable.
Frequently asked questions
Why is a commercial invoice rejected at customs?
Most often for a generic goods description, missing origin, or inconsistency with the packing list and transport document. These are documentary problems, not transport problems.
Should the tariff code appear on the invoice?
It is not always mandatory, but including it markedly reduces the risk of amendment. Verification remains the declarant’s responsibility: the supplier’s code is a starting point, not a declaration.
What is the difference between country of origin and country of dispatch?
Origin is a quality of the goods and depends on where they were produced or sufficiently transformed. Country of dispatch is simply where they leave from. Only origin unlocks preferential regimes.
How detailed must the description be?
Detailed enough to allow classification without further questions. “Spare parts” or “samples” will not do; material, function and intended use are needed.
Must the Incoterms rule be stated?
Yes, with the named place. A term without a place is incomplete and invites disputes about where risk and cost pass to the buyer.
What happens under a documentary credit?
The bank compares the documents against the credit text. A discrepancy, even a formal one, can lead to rejection and suspend collection although the goods arrived correctly.
Are a proforma and a commercial invoice the same?
No. A proforma is an offer document with no accounting value; the commercial invoice accompanies the shipment and serves customs clearance. Many disputes arise from using one in place of the other.
Who checks the documents before departure?
On shipments we handle, we do, together with customs clearance. It is the check that prevents most holds.
Send us a real invoice before your next shipment. We will tell you what is missing so the goods do not stop — and, if a documentary credit is open, whether the required documents can be produced under the term you agreed.
