Sourcing densified wood bearing blanks from China

Duty on densified wood bearing blanks

Read from the UK Trade Tariff on 4 October 2026, heading 4413 covers densified wood in blocks, plates, strips or profile shapes. Code 4413 00 00 00 carries 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspension or attached import control. The table shows different blank forms sharing this single commodity line.

Confirm with OPSS whether these densified wood products fall within the timber regulation and what due-diligence system the importer first placing them on the Great Britain market should use. Gather species, country-of-harvest and legal-harvesting evidence for review. A tariff record without attached controls does not replace checks on the applicable timber requirements.

Confirm the commodity code using the material construction and the form shipped, especially where machining produces a finished bearing rather than a blank. See the wider densified wood guide for other applications and UK import duty and VAT for the tax calculation.

Specify the bearing application and blank construction

Give the factory the intended shaft material, bearing load, movement, lubrication and operating environment. Ask it to identify the proposed wood species, resin system and laminate direction. Agree density, hardness and moisture acceptance criteria against an approved sample. Specify a mechanical bearing grade rather than accepting an electrical insulation grade as evidence of suitability.

Provide a drawing showing the blank dimensions, machining allowance and laminate orientation relative to the bearing surface. Agree whether the supplier delivers solid stock or a rough-bored blank. Ask for trial machining and an application test before approving production. Obtain species, harvest-origin and legality documents before ordering.

Worked duty example

Illustrative example, not a quote: Illustrative order: 30 densified wood bearing blanks for an engineering workshop under 4413 00 00 00, invoiced at £2,500 free on board, with £1,530 of freight and insurance to the UK. The customs value is £4,030. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,030, so it is £806. 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

Dimensions: measure the blank and any rough bore against the drawing, including the stock left for final machining.

Material condition: check sample density, hardness and moisture against the agreed specification, and examine packs for dampness, distortion or cracks.

Bonding and machining: machine sample blanks and inspect exposed laminations for open glue lines, delamination and edge breakout.

Batch identity: match pack labels to material records, the approved construction and the timber documentation. Record findings using the quality inspection guide.

What goes wrong

A blank can look sound but expose open glue lines when bored. Damp material can distort after machining, while insufficient machining allowance leaves no room to correct the bearing surface. A changed laminate direction or material grade can also undermine the approved trial. Check the delivered batch against the sample and drawing before machining the full order.

A factory invoice showing Chinese manufacture does not establish the country of harvest. The due diligence file can fail to trace the timber used in the laminations. Collect the supporting documents before shipment and resolve gaps before placing the goods on the Great Britain market.
