Sourcing wooden staircases from China
The relevant staircase candidate lines carry 0% UK duty from China, while heading 4418 ranges from 0% to 2%. Importers first placing covered timber products on the Great Britain market must exercise timber due diligence. Confirm the kit's classification and site drawings before ordering. Cambridge China Bridge sources prefabricated wooden staircases.
Staircase candidate lines carry zero duty
Read from the UK Trade Tariff on 7 October 2026, heading 4418 covers builders' joinery and carpentry of wood. The staircase candidate lines shown carry 0% duty from China, with no recorded anti-dumping or countervailing duty and no suspension. Across the wider heading, duties range from 0% to 2%.
The supplied tariff data attaches a DCMS export-licence control to these lines. Ask your customs broker to confirm its relevance to the transaction. Do not treat that export entry as confirmation of an import-licence requirement.
These are classification candidates, not interchangeable staircase codes. Give your broker the species, construction, assembly drawings and packing list, distinguishing complete kits from separately supplied structural products, and confirm the commodity code. For wider heading coverage, see prefabricated timber roof trusses.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |

| Other wooden joinery: candidate line for wooden staircase kits | 4418 99 00 00 | 0% | None |
| Other bamboo joinery: candidate line for bamboo staircase kits | 4418 91 00 00 | 0% | None |
| Other engineered structural timber products, if supplied separately | 4418 89 00 90 | 0% | None |
| Other engineered structural bamboo products, if supplied separately | 4418 89 00 10 | 0% | None |
Specify the staircase against the finished opening
Agree finished floor levels, opening dimensions, rise, going, pitch, headroom, flight width, landings and turning direction on signed drawings. Identify stringers, treads, risers, newels, handrails and guarding, with joint details, fixing locations and installation instructions. Specify timber species, solid or laminated construction, finish and an agreed moisture range.
In England, Approved Document K provides guidance covering staircase design and guarding. Ask the project designer to review the proposed staircase against the installation before approving manufacture. Collect species, harvest origin and supporting legality documents for every wood component, and confirm with the relevant authority whether the staircase kit falls within timber due diligence requirements.
Worked duty example
Illustrative example, not a quote: Illustrative batch of prefabricated wooden staircase kits for a small building project under 4418 99 00 00, invoiced at £22,000 free on board, with £3,500 of freight and insurance to the UK. The customs value is £25,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £25,500, so it is £5,100. 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
Geometry: compare the kit with the signed drawings, checking tread and riser consistency, landing connections, stringer profiles and the finished floor interface.
Assembly: trial-fit a representative kit, checking joints, fixing holes, handrail connections and the completeness of labelled components.
Timber: measure moisture against the agreed range and inspect for splits, loose knots, bowing, glue-line separation and finish damage.
Packing: check part identification, protected nosings and edges, dry wrapping and the hardware inventory during quality inspection; repeat condition and completeness checks on arrival.
What goes wrong
A staircase made to unfinished floor levels can leave an uneven step at the landing. Reversed turning directions, misplaced fixing holes and missing newels can stop installation even when the timber looks acceptable. Resolve drawing revisions and trial-fit findings before packing.
Wet timber can distort during transport or after installation; poorly bonded laminated treads can separate, and exposed nosings can arrive chipped. Photograph arrival damage before unpacking further and retain component labels. Missing harvest evidence also leaves the importer unable to substantiate timber legality.

Frequently asked questions
What is the UK import duty on wooden staircases from China?
The relevant candidate lines in the supplied tariff data carry 0% duty, with no recorded anti-dumping or countervailing duty. Heading 4418 overall ranges from 0% to 2%. Confirm the exact kit's code.
Do imported wooden staircases need timber due diligence?
Confirm with the relevant authority whether the builders' joinery under heading 4418 falls within timber due diligence requirements. Where covered, the business first placing it on the Great Britain market must exercise due diligence on timber legality. Collect species and harvest-origin information for that review.
Which drawings should I send a Chinese staircase factory?
Send measured finished floor levels, opening dimensions, flight and landing layouts, turning direction, joint details and fixing locations. Have the project designer approve the manufacturing drawings.
What should I check when staircase kits arrive?
Check component labels and completeness, moisture, distortion, tread edges, glue lines and finish damage. Compare geometry and joints with the approved drawings before installation.
