Machinery shipments are held at ports far more often for paperwork than for anything wrong with the machines. Missing or mismatched documents cause storage charges, demurrage and delays that dwarf the cost of getting the file right at the start. This is the complete document set for a machinery import, who issues each one, and the mismatches that cause most holds.
The four documents that travel with every shipment
1. Commercial invoice
Issued by the supplier. It states the seller and buyer, the goods description, quantity, unit price, total value, currency and the agreed incoterm. Customs assesses duty on this document, so the value must match the contract and the payment records exactly.
Common failure: a description so vague — “machinery parts” — that the customs broker cannot classify it. The invoice should name the machine, its model and its function.
2. Packing list
Issued by the supplier. It lists every package with its dimensions, weight and contents, and reconciles against the invoice. It is what the port uses to check that nothing is missing when the container is opened.
Common failure: quantities on the packing list that do not match the invoice, usually because spare parts or accessories were added at loading and never added to the paperwork.
3. Bill of lading (B/L)
Issued by the shipping line or forwarder. It is the transport contract and the document of title — whoever holds the original can claim the goods. Because of that, the B/L is usually released against payment of the balance, which is what gives the balance payment its leverage.
Common failure: a consignee name or address that does not match the importer of record, which forces an amendment and delays release.
4. Certificate of origin
Issued by a chamber of commerce or an authorised body in the country of export. It declares where the goods were manufactured. It matters when a trade agreement between China and your country gives a preferential duty rate — without a valid origin certificate you pay the standard rate.
Compliance documents by market
United States — EPA certificate of conformity
Non-road spark-ignition engines above a certain size must have an EPA certificate of conformity, and the engine must carry the required emission label. This is issued against the engine, so a substitution of engine model at the factory invalidates it. Ask for the certificate for the exact engine you ordered.
European Union — CE declaration and technical file
The EU Declaration of Conformity is the manufacturer’s legal declaration that the machine meets applicable directives. Supporting it are the technical file, engine Stage V approval evidence, and for outdoor equipment such as mowers the noise test data and marking. See the CE marking guide for the full picture.
Other markets
Many countries require their own conformity approval, and some require pre-shipment inspection by a nominated agency. Ask before you order — these are not documents a factory can produce retroactively.
Supporting documents worth requesting
- Insurance certificate — proof of marine cover for the shipment.
- Fumigation or heat-treatment certificate — required for solid wood packing in many markets, and increasingly for pallets and dunnage.
- Loading photographs and a loading plan — not customs documents, but your evidence if the shipment is damaged or short-landed.
- Operator and maintenance manuals — in the language of the destination market, shipped with the machine rather than emailed afterwards.
- Spare parts list with part numbers — what you will need long after the shipment clears.
- Test or inspection certificate — where the buyer’s contract requires a pre-shipment inspection report.
The mismatches that cause most holds
- Consignee vs importer of record. The name on the bill of lading must be the entity clearing the goods. Group structures and trading names are the usual culprits.
- Value discrepancies. If the invoice value does not match the bank transfer or the contract, customs will query it.
- Description too vague to classify. The broker needs to assign a harmonised system code; a description that could cover three different machines stalls the entry.
- Missing origin certificate when a preferential rate is claimed. Without it you pay the standard duty and lose the saving.
- Conformity documents naming a different model. A certificate for a similar machine is not a certificate for your machine.
- Wood packing without treatment marking. Untreated solid wood crates and dunnage can be refused or require on-site treatment.
A timeline that avoids demurrage
- Before ordering — confirm with your broker which compliance documents your market requires, and ask the supplier whether they can issue them.
- Before production — agree the machine specification in writing, so the documents describe what is actually built.
- Before shipment — review the draft invoice, packing list and bill of lading for name, address, description and value accuracy. This is the cheapest moment to fix a mistake.
- Before releasing the balance — confirm the originals and the conformity documents exist.
- Before arrival — send the document set to your broker so the entry can be prepared ahead of the vessel.
Frequently asked questions
What documents come with a machinery shipment from China?
Commercial invoice, packing list, bill of lading and certificate of origin as standard, plus the conformity documents for your market — an EPA certificate of conformity for the United States, or a CE declaration for the European Union.
Do I need a certificate of origin?
Always useful, and essential if you are claiming a preferential duty rate under a trade agreement. Without it you pay the standard rate.
Why is my container being held at the port?
Usually a document mismatch — consignee name, invoice value, a description too vague to classify, or a missing conformity document. Ask the broker which specific entry line was queried.
Does the machine ship with a manual in my language?
Yes, in the language of the destination market and packed with the machine. It should not be emailed separately, because several markets require it to travel with the goods.
Can you provide the EPA or CE documents?
Yes. Machines for the United States ship with an EPA certificate of conformity and the required emission labelling; machines for the European Union ship with the EU Declaration of Conformity, CE plate, engine Stage V approval and noise test data.
