Sourcing excavator hydraulic breakers from China
The relevant other-parts lines under heading 8431 carry 0% UK duty for goods from China, subject to confirming the product's classification. Hydraulic hammers need outdoor-noise marking; agree carrier compatibility and check the model documents before ordering. Cambridge China Bridge sources excavator hydraulic breakers.
Duty depends on the breaker and its construction
Heading 8431 covers parts suitable solely or principally for the machinery described in the tariff. For this guide, the relevant candidate lines are other cast iron or cast steel parts and other parts of excavating machinery. The table repeats these lines for different purchasing descriptions; it does not establish the classification of a complete hydraulic breaker.
Read from the UK Trade Tariff on 4 October 2026, these candidate lines carry 0% duty on goods from China. The supplied tariff facts list no anti-dumping or countervailing duty, suspension or attached import control for either line. Measures on access-platform parts elsewhere in the heading should not be applied to these breaker-part lines.
Give your broker the assembly drawing, materials, carrier application and details of whether the shipment contains a complete breaker or separate parts. Confirm the commodity code before ordering. For other excavator attachments in this heading, see excavator buckets.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cast iron or cast steel breaker housings, subject to classification | 8431 49 20 90 | 0% | None |
| Other excavator breaker assemblies, subject to classification | 8431 49 80 90 | 0% | None |
Specify the carrier, mounting and hydraulic circuit
Name the excavator model and coupler, and supply a mounting drawing showing pin diameters, pin centres and bracket width. Agree breaker operating weight, tool shape, housing style and the intended work. Ask the factory to identify compatible carriers rather than relying on a general excavator weight range.
Specify required oil flow, operating pressure, permitted return pressure, hose connections and any drain-line arrangement. Agree tool steel, heat treatment, bush and retaining-pin details, lubrication instructions, gas-charging information and replacement seal availability. Request a loaded demonstration with the test circuit settings recorded.
Hydraulic hammers are listed as equipment subject to outdoor-noise marking only. They need a guaranteed sound power label, supporting measurement documentation and a declaration of conformity. Ask for these for the actual breaker model, alongside its English operating and maintenance instructions.
Worked duty example
Illustrative example, not a quote: Illustrative shipment of compact excavator breaker assemblies, subject to classification under 8431 49 80 90, invoiced at £12,800 free on board, with £2,000 of freight and insurance to the UK. The customs value is £14,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £14,800, so it is £2,960. 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
Mounting: measure the bracket and pins against the approved drawing, inspect welds and check coupler engagement on the intended carrier.
Hydraulics: check hose ratings, connections and routing; inspect for leakage during the agreed loaded test and record the circuit settings.
Wear parts: check tool dimensions, material and hardness records, bush clearance, retaining pins and the agreed spare-parts identification.
Documents and arrival: match the delivered model to the declaration and noise label, check the manual, and inspect hoses, tools and mounting faces for transit damage. Arrange inspection before shipment.
What goes wrong
A breaker can fit the excavator's weight category but still have the wrong bracket or hydraulic requirements. Excessive return pressure, unsuitable hose connections and poorly matched flow can cause overheating, leakage or weak striking. Treat the carrier and breaker as a matched purchase specification.
Soft tools, incorrect bush clearance and weak retaining parts cause premature wear or tool movement. A generic certificate does not show that the delivered model matches the noise evidence. Resolve drawing, test and document discrepancies before releasing the shipment.

Frequently asked questions
What is the UK import duty on hydraulic breakers from China?
The candidate other-parts lines 8431 49 20 90 and 8431 49 80 90 carry 0% duty, with no trade remedy listed in the supplied facts. Confirm the complete breaker's classification before using either code.
Will a hydraulic breaker fit my excavator?
Check the carrier model, coupler drawing, pin dimensions, bracket width, operating weight and hydraulic circuit. A matching excavator weight range alone does not establish compatibility.
Do excavator hydraulic breakers need noise labels?
Yes. Official guidance lists hydraulic hammers under noise marking only. Obtain the guaranteed sound power label, measurement documentation and declaration for the delivered model.
What should I test before shipment?
Check mounting dimensions, tool and bush fit, retaining parts, hose connections and leakage. Agree a loaded test with recorded flow and pressure, and match the documents to the tested model.
