Containers get held because of paper, not because of machines. We ship every week and we have never seen a crane care how a hydraulic hose is routed. We have seen a broker stop a forty-foot box over one wrong letter in a company name. Storage, demurrage, a re-issued bill of lading, a truck sent home empty: all of that costs more than getting the file right at the start, and it is the part of the order nobody prices.
So here is the document set for a machinery import, who issues each piece, and the mismatches that actually cause holds at the port.
The four documents that travel with every shipment
1. Commercial invoice
The supplier issues it. Seller and buyer, goods description, quantity, unit price, total value, currency, agreed incoterm. Customs assesses duty on this one document, so the value has to match the contract and the money that moved through the bank. Brokers read it first and they read it closely.
Where it normally goes wrong is the description. Something like “machinery parts” tells a broker nothing, so nobody can classify it. Name the machine, the model and what it does. That one line decides the HS code, and the HS code decides what happens next.
2. Packing list
Also from the supplier. Every package, with dimensions, weight and contents, reconciled against the invoice. When the container is opened, this is the sheet the port works from to check nothing walked.
The usual failure is a quantity that drifted. Spare parts or accessories get added at loading, somebody drops them in the box, nobody updates the list. Now the invoice and the packing list disagree, and you are standing at a customs desk explaining why.
3. Bill of lading (B/L)
The shipping line or the forwarder issues it. It is the transport contract and the document of title at the same time, which means whoever holds the original can claim the goods. That is exactly why the B/L is normally released against payment of the balance. The paper is what makes the buyer settle before the machines move.
Consignee name and address are where this one breaks. Miss the match with the importer of record and you need an amendment, and an amendment costs days you did not plan for.
4. Certificate of origin
A chamber of commerce or an authorised body in the exporting country issues it. It states where the goods were manufactured. It matters most when a trade agreement between China and your country gives a preferential duty rate. Claim the preference without a valid origin certificate and you pay the standard rate.
Compliance documents by market
United States: EPA certificate of conformity
Non-road spark-ignition engines above a certain size need an EPA certificate of conformity, and the engine has to carry the required emission label. The certificate is issued against a specific engine, so if the factory substitutes an engine model at build time, the certificate is void. Ask for the certificate for the exact engine on your order.
European Union: CE declaration and technical file
The EU Declaration of Conformity is the manufacturer’s legal statement that the machine meets the applicable directives. Behind it sits the technical file, the engine Stage V approval evidence, and for outdoor equipment such as mowers the noise test data and the marking. Our CE marking guide walks through the whole chain.
Other markets
Plenty of countries want their own conformity approval, and some insist on pre-shipment inspection by a nominated agency. Ask before you order. A factory cannot produce these retroactively, and nobody can conjure them from a photograph after the vessel has sailed.
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 they are your evidence if the shipment is damaged or short-landed.
- Operator and maintenance manuals. In the language of the destination market, packed with the machine rather than emailed afterwards.
- Spare parts list with part numbers. You will want this 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 against importer of record. The name on the bill of lading must be the entity clearing the goods. Group structures and trading names trip this up constantly.
- 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 has to assign a harmonised system code. A description that could cover three different machines stalls the entry while somebody works out which one you bought.
- Missing origin certificate when a preferential rate is claimed. Without it you pay the standard duty and the saving is gone.
- 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 outright or need 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 actually issue them.
- Before production: agree the machine specification in writing, so the documents describe what gets built rather than what was discussed.
- Before shipment: review the draft invoice, packing list and bill of lading for name, address, description and value. This is the cheapest moment to fix a mistake, and the last cheap one.
- Before releasing the balance: confirm the originals and the conformity documents exist. Once the money is out, your hold on the goods is out with it.
- Before arrival: send the document set to your broker so the entry can be prepared ahead of the vessel.
Questions we get asked
What documents come with a machinery shipment from China?
Commercial invoice, packing list, bill of lading and certificate of origin come as standard. Add the conformity documents for your market, which means an EPA certificate of conformity for the United States or an EU Declaration of Conformity for Europe. We also send manuals, a spare parts list and loading photographs.
Do I need a certificate of origin?
It is always useful, and essential if you are claiming a preferential duty rate under a trade agreement. Without a valid certificate you pay the standard rate and lose the saving entirely. Ask for it when you place the order, because chasing one after the vessel has sailed is slow and awkward.
Why is my container being held at the port?
Usually a document mismatch. The consignee name, the invoice value, a description too vague to classify, or a missing conformity document. Ask the broker which specific entry line was queried, and get that answer in writing. Vague answers from a forwarder cost you demurrage, and demurrage is charged by the day, not by the mistake.
Does the machine ship with a manual in my language?
Yes, in the language of the destination market, packed inside the container with the machine rather than emailed afterwards. Several markets require the manual to travel with the goods, so a PDF sent after arrival does not satisfy an inspector. Tell us the language when you order and we print it before loading.
Can you provide the EPA or CE documents?
Yes. Machines bound 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, the CE plate, engine Stage V approval evidence and the noise test data for outdoor equipment.
