Sourcing woodworking tenoning machines from China

Duty and classification for tenoning machines

Read from the UK Trade Tariff on 21 October 2026, heading 8465 covers machine tools for working wood and similar hard materials. Tenoning machines cut the projecting joint; mortising machines cut the receiving hole. For the wider heading and the distinction, see our woodworking mortising machines guide.

Every line in the supplied tariff facts carries 2% duty for goods from China. No anti-dumping or countervailing duty, tariff suspension or attached import control is listed. The table shows classification options for different machine configurations, rather than interchangeable codes for any tenoner.

Give your customs broker the cutter arrangement, machining functions, tool-change method and workpiece-transfer details. Confirm the commodity code before ordering, especially for machines combining sawing and tenoning or machining centres producing tenons.

Specify the tenon and the machine together

Provide joint drawings and representative timber, including species, section and moisture condition. Specify tenon length, thickness, width, shoulder position, permitted variation and the mating mortise. State whether you need single-end or double-end machining, square or rounded profiles, angled shoulders and scribing for profiled components.

Agree cutter layout, tooling included, spindle rotation, adjustment method, carriage travel, clamping, supply voltage, phase, frequency and extraction connections. Specify an English manual and electrical schematic. For supply in Great Britain, confirm the applicable conformity assessment, CE or UKCA marking and declaration of conformity requirements with the relevant authority; the responsible person must compile the technical file and make it available on request.

Worked duty example

Illustrative example, not a quote: One woodworking tenoning machine classified as a milling machine, illustrative only under 8465 92 00 00, invoiced at £8,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £9,200. Duty at 2% is £184. Import VAT at 20% is charged on the customs value plus duty, £9,384, so it is £1,876.80. Import taxes total £2,060.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £184 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Joint accuracy: cut your timber on the production machine, measure the tenon and shoulders against the drawing, and test the fit in your mating mortise after repeated machining.

Clamping and movement: check that short and profiled workpieces remain secure, the carriage moves smoothly, and stops and adjustments retain their settings.

Guarding and controls: HSE highlights guarding because the operator works close to the cutting heads. Have a competent inspector check cutter access, guard adjustment, emergency stops and stopping behaviour.

Arrival condition: check for damaged guards, displaced stops, rust and loose components. Match the nameplate and documents to the delivered machine, then repeat the agreed cutting trial after installation. Plan the checks with our quality inspection guide.

What goes wrong

A machine can produce an acceptable demonstration joint yet lose shoulder alignment during repeated cuts. Weak clamping, unsuitable cutters and difficult adjustments can leave loose joints, torn grain or inconsistent tenon thickness. Specify acceptance against your drawing and timber rather than a supplier's display sample.

Check that guards still work with your actual component shapes and that extraction connections suit the workshop system. Settle installation, operator instruction, replacement cutters and spare clamping parts before shipment. Use our quote check service to review what the supplier has included.
