Sourcing Vibroflotation Machines from China

UK duty and classification

Heading 8430 covers machinery for working earth, minerals or ores, including compacting and sinking machinery. For a vibroflotation purchase, distinguish the suspended vibrating probe and power pack from a complete self-propelled carrier. The table gives classification options to review against the actual equipment, rather than interchangeable codes.

Read from the UK Trade Tariff on 1 October 2026, every line in heading 8430 carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions or attached import controls. Import VAT is separate from customs duty.

Ask your customs broker to confirm the commodity code using the machine's function, propulsion, drawings and shipment contents. Review the boring or sinking option only where that description fits the equipment. See the wider compactors and piling rigs guide for other machinery within this heading.

Specify the probe and its working system

State whether the machine will densify granular soil or install stone columns, and whether aggregate feeds from the top or through the probe. Specify working depth, probe diameter, vibration frequency, centrifugal force, motor power and the extension arrangement. Have the ground improvement designer approve the intended method and acceptance criteria.

Agree electrical or hydraulic drive, power supply compatibility, cooling, water or air connections, hose and cable lengths, lifting connections and carrier compatibility. List the power pack, control cabinet, feed equipment, wear nose, seals, bearings and spares included in the shipment.

For complete machines supplied in Great Britain, confirm with the relevant machinery-safety authority the applicable conformity requirements under the Supply of Machinery (Safety) Regulations 2008, including technical file arrangements, a declaration of conformity, CE or UKCA marking and English instructions. The responsible person must ensure the essential health and safety requirements are satisfied. Define whether the purchased assembly is complete machinery and agree the documentation scope before ordering.

Worked duty example

Illustrative example, not a quote: One non-self-propelled vibroflotation machine with power pack, illustrative only under 8430 61 00 00, invoiced at £60,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £64,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £64,000, so it is £12,800. 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

Probe and wear parts: check dimensions against drawings, inspect the nose and extension joints, and confirm replacement bearings, seals and wear parts match the supplied assembly.

Operation: witness the agreed factory run, record current or hydraulic pressure and bearing temperature, and check cooling flow, leakage, emergency stops and cable protection.

Feed and handling: inspect aggregate passages where fitted, lifting connections, hose restraints and the interface with the intended carrier. Check that components can be assembled using the supplied instructions.

Arrival and documents: reconcile serial numbers with the declaration and packing list, inspect cables and hoses for transport damage, and check English operating and maintenance instructions. Use a written inspection brief.

What goes wrong

A probe can run at the factory yet perform poorly in the intended ground. Risks to check include unsuitable vibration settings, restricted aggregate passages, overheating bearings, leaking seals and extension joints that loosen during operation. A factory run alone does not establish ground treatment performance.

Another purchasing problem is an incomplete working system: the quoted probe arrives without compatible controls, cooling equipment or carrier connections. Agree the complete supply boundary, an acceptance test and a spares list before payment, then compare the shipped equipment with the approved drawings.
