How to Import Generator Sets from China: Documentation, Payment and Freight

If you are importing generator sets from China for the first time, the machine itself is rarely what causes problems. The delays, extra charges and customs holds almost always come from documentation, payment terms or freight decisions made before the order was placed.

This guide covers the practical side: what documents you need, how payment is normally structured, and how to plan container loading so freight does not eat your margin.

1. The document set you need before shipping

Every consignment needs all of these, and missing any one of them will stop the container at the port:

• Commercial Invoice — must match the sales contract exactly: model, quantity, unit price, total value, Incoterms.
• Packing List — broken down by model: quantity, net weight, gross weight, dimensions, package type.
• Bill of Lading (B/L) — issued by the shipping line. Check the consignee and notify party character by character; one spelling error means an amendment fee and lost days.
• Certificate of Origin — this is what determines your duty rate. If your country has a preferential trade agreement and you receive the wrong form, it can cost you several percent of the total value.
• Test Report — each unit should be load-tested before dispatch. Ask for the individual test sheet, not a generic quality certificate that covers the whole production run.
• CE / EPA certificate — depending on your market’s requirements.
• Insurance certificate — if you bought on CIF terms.

A manufacturer who exports regularly will provide all of this as standard, without being asked twice. If you find yourself chasing documents after the container has sailed, that is worth noting for next time.

2. Payment terms: what is normal

The standard arrangement for a first order is 30% deposit by T/T, 70% against the B/L copy. This protects both sides: the deposit covers the manufacturer’s material cost, and the balance is released only once the goods are demonstrably on board.

The 70% should be paid against a copy of the bill of lading — not against a promise that it will be issued. After payment you should receive the original B/L or a telex release within a few days.

A Letter of Credit is the alternative. It costs more in bank charges and takes longer to arrange, but it is worth considering for a first order above roughly USD 50,000, or where you have no trading history with the supplier.

What to avoid: paying 100% up front, and paying into a personal account rather than a company account. Both remove your only real leverage if something goes wrong.

3. Freight: the decision that quietly costs the most

Sea freight for generator sets is usually quoted per container, so units per container directly determines your landed cost per unit.

As a rough reference for small sets:

• 2–5 kW open frame gasoline — around 130–290 units per 40 ft container
• 5–10 kW single-cylinder diesel — around 40–90 units per 40 ft
• 10–18 kW twin-cylinder — around 20–80 units per 40 ft

Exact figures depend on canopy type — silent sets are bulkier than open frame — and on packing method. Always ask for the manufacturer’s container loading plan before finalising, because it tells you whether your order is worth shipping as-is or should be topped up with another model.

Mixed models are usually possible. If your first order is small, ask whether several models can share one container. That lets you test the market without committing a whole container to a single size — a common approach for distributors entering the small generator segment.

4. Customs: get the HS code right

Generator sets generally fall under HS heading 8502 (electric generating sets). Sub-headings differ by output range and by whether the set is diesel or gasoline powered. Welder-generator combinations may classify differently again.

Ask your supplier for the HS code they normally declare, then confirm it with a customs broker in your own country. Duty rates vary considerably between markets, and some countries apply additional levies on generating equipment.

5. Four mistakes that cost importers the most

• Buying on price alone. Two sets with the same kW rating can differ substantially in alternator, engine brand, control panel and canopy. Ask for the full specification, not just the headline number.
• Ignoring the spare parts plan. Order filters, injectors and common wear parts in the first container. Waiting two months for a filter costs far more than the filter.
• Wrong voltage or frequency. Most of Africa and Europe runs 50 Hz at 220–240 V, but several markets need 60 Hz. Confirm this before production — it cannot be changed afterwards.
• Not checking certification requirements. Some markets require specific import certification for generating equipment. Check before you order, not when the container arrives.

Working with a manufacturer rather than a trading company

For small generator sets, working directly with the factory has two practical advantages. First, technical questions get answered by someone who knows the production line, not a sales intermediary. Second, spare parts remain available years later, because the same factory still builds the model.
