Sourcing carton sealing machines from China
Carton sealing machines from China carry 0% UK import duty under the container-sealing line of heading 8422. New machines placed on the Great Britain market must have CE or UKCA marking, a declaration of conformity and English instructions. Cambridge China Bridge sources carton sealing machines.
Duty and classification for carton sealers
Heading 8422 covers container filling, closing, sealing and labelling machinery, alongside other packaging machinery and dishwashers. Carton sealing machines fit the container-sealing description under 8422 30 00 00. The table distinguishes machine configurations sharing that code; it also includes dedicated parts whose classification needs checking.
Read from the UK Trade Tariff on 30 September 2026, the listed machine and parts lines carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions or attached import controls for these lines. Import VAT is normally 20%.
Confirm the commodity code from the machine's function and its condition when imported. Describe any combined packing equipment and separately shipped parts to your customs broker. For related machinery within this heading, see automatic strapping machines.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Carton sealing machines with manual size adjustment | 8422 30 00 00 | 0% | None |
| Dedicated carton sealing machine parts, subject to classification | 8422 90 90 00 | 0% | None |
Specify cartons, tape heads and line interfaces
State the smallest and largest carton dimensions, filled weight, board type and whether sizes change between batches or within a batch. Specify manual or automatic adjustment, who folds the flaps, and whether the machine seals the top, bottom or both. Send representative filled cartons and your intended tape to the factory.
Agree tape width, roll core, adhesive type, tape overlap, belt arrangement and conveyor height. For an automatic flap folder, include misshapen cartons and uneven loads in the trial. Confirm the electrical supply, any compressed-air connection, upstream and downstream signals, and access for changing tape and replacing blades.
For supply in Great Britain, new machinery must carry CE or UKCA marking and come with a declaration of conformity and English instructions. Confirm conformity assessment, technical file and guarding requirements with the relevant authority for the packaging machinery. Match the documents to the supplied model and configuration; arrange testing and certification checks before shipment.
Worked duty example
Illustrative example, not a quote: Illustrative batch of 15 carton sealing machines under 8422 30 00 00, invoiced at £75,000 free on board, with £5,000 of freight and insurance to the UK. The customs value is £80,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £80,000, so it is £16,000. 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
Carton handling: run your filled cartons through the machine and check tracking, flap alignment, crushed corners, belt slip and adjustment between sizes.
Tape application: check that the tape follows the joint, adheres along its length and is cut cleanly without loose tails or lifted ends.
Safety and documents: check guarding around belts, folding arms and cutting blades; test guard interlocks and every emergency stop. Match the nameplate and declaration to the machine, and check the English manual.
Arrival condition: inspect the frame, tape heads, belts and wiring for transit damage. Confirm that agreed spare blades, rollers and belts are present, then repeat the carton trial after installation.

What goes wrong
A demonstration with empty, uniform cartons can hide poor handling of your filled boxes. Uneven loads can skew the carton; soft board can buckle under belt pressure. The wrong tape or poorly adjusted rollers can leave lifted edges, while a blunt blade produces ragged cuts.
Agree acceptance criteria using your cartons and tape before shipment. Record settings and defects during the trial, then require corrections and a repeat run. Specify replacement tape heads, belts and blades by machine configuration so that maintenance does not depend on identifying parts after a failure.
