Sourcing paper-stock hydrapulpers from China
Paper-stock hydrapulpers and identifiable pulp-making machinery parts from China carry 0% UK duty, with no anti-dumping or countervailing duty listed. Confirm machinery safety requirements, conformity documentation, marking and English instruction requirements with HSE before ordering. Cambridge China Bridge sources paper-stock hydrapulpers.
Hydrapulper duty and commodity codes
Read from the UK Trade Tariff on 7 November 2026, heading 8439 covers machinery for making pulp of fibrous cellulosic material and machinery for making or finishing paper or paperboard. A paper-stock hydrapulper making pulp belongs within the pulp-making family. The table separates operating types and identifiable parts; repeated codes represent the same tariff line.
The supplied tariff record lists 0% duty for Chinese goods under 8439 10 00 00 and pulp-making machinery parts under 8439 91 00 00. Neither line lists anti-dumping duty, countervailing duty, a suspension or an attached import control. Zero customs duty does not remove machinery safety obligations.
Confirm the commodity code against the machine's function and the shipment contents. Separately supplied motors, drives or general-purpose components need their own classification check. For other equipment in this heading, see the pulp and paper-making machinery guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Batch paper-stock hydrapulpers for making pulp | 8439 10 00 00 | 0% | None |
| Hydrapulper rotors identifiable as pulp-making machinery parts | 8439 91 00 00 | 0% | None |
Specify the fibre, consistency and discharge
State whether the feedstock is recovered paper, virgin pulp or a mixture, including likely contaminants. Specify batch or continuous operation, working stock consistency, usable tub volume, required output, motor and drive arrangement, rotor design, screen openings and reject removal. Define output using your feedstock and an agreed measure of remaining unpulped material.
Agree wetted materials, replaceable wear surfaces, seal arrangement, drainage, cleaning access and the connection layout. Request foundation loads, assembly drawings, control interfaces and a commissioning scope. Specify the spare rotor, screen plate and seal information needed to order replacements.
Confirm with HSE the applicable essential health and safety requirements under the Supply of Machinery (Safety) Regulations 2008, and the requirements for a declaration of conformity, marking and English instructions for machinery placed on the Great Britain market. CE marking continues to be recognised in Great Britain. Ask the supplier to identify the conformity route and provide documents matching the actual machine.
Worked duty example
Illustrative example, not a quote: One compact batch paper-stock hydrapulper; illustrative FOB value and freight under 8439 10 00 00, invoiced at £28,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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
Fibre trial: run the agreed feedstock and record stock consistency, pulping result, output, rejects and motor load. A water-only run does not demonstrate fibre performance.
Mechanical build: check tub welds, rotor and screen fit, wear surfaces, shaft alignment and seal leakage against approved drawings. Inspect bearings and drive components for the specified identity.
Safety and documents: check guarding around the drive and access openings, test emergency stops and access interlocks, and match the declaration, marking and English instructions to the machine.
Arrival and commissioning: check transport damage, loose fittings, corrosion, packing lists and supplied spares before assembly. Repeat the agreed fibre trial after installation; use the inspection guide to plan the checks.

What goes wrong
A pulper demonstrated on clean fibre can leave flakes or block its screen when processing your recovered paper. Poor rotor and screen matching, unsuitable reject removal or an overstated working volume can undermine output. Seal leakage, vibration and inaccessible wear parts also make routine operation harder.
Define the feedstock, acceptance method and replacement-part drawings before ordering. Agree who supplies installation work, control integration and commissioning support, and who resolves failed acceptance trials. Check the builder's workshop and comparable installations through factory verification.

Frequently asked questions
What is the UK import duty on hydrapulpers from China?
The supplied tariff record lists 0% for pulp-making machinery under 8439 10 00 00 and its parts under 8439 91 00 00, with no anti-dumping or countervailing duty.
Can a water test prove a hydrapulper's output?
A water test can reveal leaks and running problems. Agree a trial using your fibre, stock consistency and contaminants to assess pulping quality, output and rejects.
What documents should accompany a hydrapulper?
For machinery placed on the UK market, check the declaration of conformity, conformity marking and English instructions. Request installation drawings, spare-part details and the agreed acceptance record.
Can I buy replacement rotors and screen plates separately?
Yes, but match drawings, materials, mounting details and clearances to the existing machine. Confirm whether each item is an identifiable pulp-making machinery part before using the parts code.
