Sourcing paper machine dryer cylinders from China
Paper machine dryer cylinders from China, when classified as other paper-machine parts under 8439 99 00 90, carry 0% UK duty, with no trade remedy listed. Check the applicable pressure equipment conformity assessment and arrange examination before operating the steam system. Cambridge China Bridge sources paper machine dryer cylinders.
0% duty on paper-machine parts
Read from the UK Trade Tariff on 3 October 2026, heading 8439 covers machinery for making pulp or making or finishing paper or paperboard, and its parts. The recorded duty range for Chinese goods is 0% throughout. Replacement dryer cylinders identified as paper-machine parts are candidates for 8439 99 00 90.
The supplied tariff record lists no anti-dumping or countervailing duty, suspension or import control for 8439 99 00 90. The table shows different products within that same parts line, subject to classification confirmation. Its separate suction-roll shell line describes suction rolls, not dryer cylinders.
Give your customs broker drawings, the parent machine details and the condition in which each item is supplied to confirm the commodity code. Standalone dryers may fall under 8419. See the wider pulp and paper-making machinery guide for complete machines and lines.

Specify the cylinder and its steam duty
Specify shell material, diameter, face length, wall thickness, maximum allowable pressure and temperature, working steam conditions and rotational speed. Supply drawings for the journals, bearing seats, end covers, drive connection and rotary joint. Agree surface finish, run-out, balance and inspection acceptance criteria rather than accepting a catalogue drawing.
For steam-heated cylinders, confirm whether pressure equipment rules apply and obtain the manufacturer's classification and conformity assessment plan before manufacture. Applicable pressure equipment requirements must be met before supply to the Great Britain market; the assessment procedure depends on the equipment's classification. Agree the material records, pressure-test records, drawings and operating instructions to be supplied.
For the installed steam system, where a written scheme of examination is required, it must be in place before operation and the system must be examined by a competent person in accordance with it. Ask the mill's pressure-system examiner to review the proposed replacement and its documentation before ordering.
Worked duty example
Illustrative example, not a quote: One replacement paper machine dryer cylinder, illustrative only under 8439 99 00 90, 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
Identity: match the cylinder identification to the drawing revision, material records and test reports; check that supplied covers and journals belong to the agreed assembly.
Geometry: measure shell diameter, face length, bearing seats and journal alignment; review run-out, surface finish and balance results against the purchase specification.
Pressure integrity: review the agreed pressure-test and defect-examination records, including any casting repairs; inspect sealing faces, cover fastenings and steam connections.
Arrival condition: inspect for corrosion, impact damage and damaged journal protection before installation; photograph defects and reconcile the packing list. Plan checks through quality inspection.

What goes wrong
A cylinder can match the headline diameter yet have incompatible bearing seats, drive connections or rotary-joint fittings. Poor alignment or balance can cause vibration; damaged sealing faces can leak; unsuitable condensate arrangements can undermine drying performance. Require approval of interface drawings and agree how replacement performance will be checked at the mill.
Missing material traceability, unexplained casting repairs or test records for a different cylinder can delay acceptance. Do not treat a factory pressure test as the installed system's statutory examination. Check the maker's casting, machining and testing capability through factory verification, and agree document acceptance before dispatch.

Frequently asked questions
What is the UK import duty on paper machine dryer cylinders from China?
The supplied tariff record gives 0% duty for other paper-machine parts under 8439 99 00 90, with no anti-dumping or countervailing duty listed. Confirm that this code fits the cylinder supplied.
Does every paper dryer use the same commodity code?
No. A replacement paper-machine cylinder and a standalone dryer may be classified differently. Supply drawings and parent-machine details to your customs broker.
Is a factory pressure test enough before using a dryer cylinder?
No. Where a written scheme of examination applies to the installed pressure system, arrange examination by a competent person in accordance with that scheme.
What drawings should I send a Chinese dryer cylinder factory?
Send the shell, end-cover and journal drawings, bearing fits, drive and rotary-joint interfaces, steam conditions and agreed surface, run-out and balance acceptance criteria.
