Sourcing precision vacuum seeders from China

Duty and classification

Heading 8432 includes agricultural seeders and their parts. For precision vacuum seeders, distinguish no-till direct machines, central driven precision spacing seeders, other seeders and separately imported parts. Vacuum metering alone does not identify the correct line. See the wider seed drills guide.

Read from the UK Trade Tariff on 1 October 2026, all the selected lines carried 0% duty for goods from China. The supplied tariff data records no anti-dumping or countervailing duty, suspensions or attached import controls for these lines. Machinery safety obligations still apply.

Give your customs broker the drive arrangement, intended soil operation, complete-machine specification and details of any separately supplied parts. Confirm the commodity code before shipment.

Specify the seed and tractor together

State the crops, seed sizes, seed coating and seed lots the machine must handle. Agree the seed disc hole pattern, interchangeable discs, singulator adjustment, vacuum setting, row spacing, seed spacing and sowing depth. Ask for a metering demonstration using your seed, followed by a field trial at the intended working speed.

Match the hitch, lifting demand, fan drive, hydraulic connections and power take-off arrangement to your tractor. Agree hopper access, seed clean-out, fertiliser equipment if included, and transport configuration. Request a parts drawing covering discs, seals, bearings, seed tubes and openers.

For supply in Great Britain, confirm with the relevant authority the applicable machinery safety rules and requirements for CE or UKCA marking and a declaration of conformity. The responsible person must compile the technical file and make it available on request. Check the documents against the exact machine and obtain English operating and maintenance instructions.

Worked duty example

Illustrative example, not a quote: Precision vacuum seeders with central drive, illustrative batch under 8432 39 11 00, invoiced at £21,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £23,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £23,500, so it is £4,700. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.

Inspection checklist

Metering: run your seed through every row unit and record misses, doubles and seed damage against the agreed acceptance criteria. Check disc fit, singulator adjustment and seed release.

Vacuum system: check hose connections, seals, fan operation and vacuum stability across the row units. Repeat the demonstration after stopping and restarting the machine.

Field performance: check opener alignment, depth adjustment, seed placement and closing-wheel action in the intended soil. Confirm that drive settings correspond to the supplied spacing chart.

Arrival and safety: inspect the frame, row-unit alignment, hoses and connectors for transport damage. Check transmission guards, warning labels, machine identification, conformity documents, English instructions and the supplied spare parts.

What goes wrong

A demonstration with the factory's seed can conceal poor performance with your crop. Incorrect discs or singulator settings can produce misses and doubles; vacuum leaks can make metering uneven between rows. Seed tubes and openers can also undo accurate metering before the seed reaches the soil.

A seeder can fit the tractor hitch yet have an unsuitable fan drive or hydraulic demand. Agree the tractor interface and acceptance trial before ordering, then repeat the relevant checks after arrival. Keep an approved disc and seal specification so replacement parts reproduce the tested setup.
