Sourcing densified bow riser blanks from China

Duty on densified wood riser 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 measures, suspensions or attached import controls. The table shows different supply forms under the same commodity line.

This guide concerns wood stock for machining into archery risers. Finished articles need classification according to their supplied form. Confirm the commodity code using photographs, the drawing and the manufacturing description. For wider heading coverage, see our densified wood knife handle blanks guide.

Specify the blank around the riser drawing

State the wood species, densification process, resin system, colour arrangement and lamination direction relative to the finished riser. Agree blank dimensions, flatness, machining allowance, density and moisture acceptance criteria. Mark the intended limb attachment areas on the drawing so the supplier understands where cracks, voids and open glue lines would be unacceptable.

Approve a sample by machining the limb attachment areas, grip and any insert holes using the intended workshop process. Check edge breakout, drilling behaviour, insert retention and the proposed finish. Material approval should include trials against the intended riser design and loading conditions.

Confirm with the relevant timber authority whether densified wood is covered by the timber regulation and what legal-harvest due diligence applies to the importer first placing it on the Great Britain market. Ask what species, harvest-country and supporting legality information is needed. Businesses reselling timber already on that market must retain records of their suppliers and the traders they sell to.

Worked duty example

Illustrative example, not a quote: 30 densified wood archery riser blanks; illustrative order and values under 4413 00 00 00, invoiced at £2,500 free on board, with £310 of freight and insurance to the UK. The customs value is £2,810. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £2,810, so it is £562. 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 thickness, width, length and flatness against the drawing, including the allowance needed to machine the limb attachment areas.

Laminations: check orientation, colour sequence, cracks, voids and open glue lines; machine a sample to expose hidden bonding defects.

Density and moisture: compare measured results with the approved sample and order specification; inspect wrapping for dampness and mould.

Machining and traceability: trial the agreed drilling and insert installation process, and match each batch to its species, harvest origin and legality documents.

What goes wrong

A blank can match the colour sample but have the wrong lamination direction or too little material around a limb attachment. Hidden voids and weak glue lines may emerge during drilling or profiling. Uneven resin impregnation can change machining behaviour, while damp stock may move after unpacking.

Compare production material with the approved machined sample, retain batch identification and resolve missing timber documents before shipment. Agree how cracked, delaminated or undersized blanks will be handled before placing the order. Use a product-specific brief for quality inspection.
