Sourcing walking excavators from China

Walking excavator duty and classification

Heading 8429 covers self-propelled earthmoving machinery. This guide covers walking excavators, also called spider excavators, with independently adjustable supporting legs. For non-tracked machines with a 360° revolving superstructure, check 8429 52 90 00. The table shows configurations within that shared code, rather than separate tariff subdivisions. See the amphibious excavator guide for wider heading coverage.

Read from the UK Trade Tariff on 30 September 2026, the relevant non-tracked excavator lines carry 0% customs duty for goods from China. The supplied records list no anti-dumping or countervailing duty, suspension or attached import control for 8429 52 90 00 or 8429 59 00 00. These findings should not be applied to track-laying excavators.

Where the machine lacks a fully revolving superstructure, check the other excavator line, 8429 59 00 00. Confirm propulsion, running gear and rotation using finding your commodity code, supplying your customs broker with drawings and photographs. Import VAT is normally 20%; see the import duty and VAT guide.

Specify the legs, working envelope and engine

Specify independent leg movement, support-foot design, wheel drive and steering where fitted. Record the intended ground conditions, working mass, boom reach, digging depth, transport configuration and attachment interface. Request the manufacturer's operating limits for slope, reach and support positions, with evidence for the actual configuration. Agree a demonstration within those limits rather than accepting a general claim that the machine works on steep ground.

Confirm the applicable CE or UKCA marking, declaration of conformity and English-instruction requirements for new machinery placed on the Great Britain market with the relevant authority. The responsible person must ensure the technical file is compiled and available on request. Request documents identifying the delivered model through testing and certification.

For a new combustion-engined machine, request engine type-approval evidence and photographs of its approval markings. Type approval demonstrates compliance with the latest emissions standards. Obtain the outdoor-noise assessment and guaranteed sound power information described in the site's excavator guidance. Equipment within the outdoor-noise rules must be accompanied by a declaration of conformity.

Worked duty example

Illustrative example, not a quote: One walking excavator for a contractor; illustrative order under 8429 52 90 00, invoiced at £60,000 free on board, with £5,000 of freight and insurance to the UK. The customs value is £65,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £65,000, so it is £13,000. 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

Legs and supports: check independent movement, pins, bushes, welds and support feet. With the machine safely supported, check for unintended movement or cylinder drift using the manufacturer's test procedure.

Hydraulics and boom: warm the machine, operate leg adjustment, boom movement and rotation, and inspect cylinders, hoses and joints for leaks. Check hose clearance throughout the agreed movement range.

Travel and stability: check powered wheels, steering and brakes where fitted. Witness an agreed digging demonstration within the manufacturer's operating limits and record the support positions and attachment used.

Identity and arrival: match machine and engine plates to the order and compliance documents. Check English instructions, noise information and the parts catalogue during quality inspection. Repeat the condition checks on arrival, recording damage and missing equipment.

What goes wrong

A demonstration on level ground can leave leg holding, uneven-ground operation and hose clearance untested. Potential faults include worn pivots, support cylinders that drift under load, damaged feet and hoses that rub when a leg extends. Make acceptance depend on a recorded test of the ordered configuration within the manufacturer's limits.

A supplier may substitute the engine, hydraulic valves or attachment coupling while retaining documents for the original model. Compare the delivered components and identification plates with the agreed specification before shipment. Resolve document mismatches and missing parts information before accepting the machine.
