Sourcing rubber dredging hoses from China
Rubber dredging hoses from China carry a flat 2% UK duty across the relevant heading 4009 lines. For pressure-service hoses, assess whether pressure-equipment rules apply, including exclusions, before supplying them in Great Britain. Cambridge China Bridge sources rubber dredging hoses.
Duty and classification for dredging hoses
Read from the UK Trade Tariff on 1 October 2026, heading 4009 covers tubes, pipes and hoses of vulcanised rubber other than hard rubber, with or without fittings. For dredging hoses, distinguish metal-only, textile-only and mixed or other reinforcement, then whether fittings are attached.
The relevant lines for Chinese-origin dredging hoses carry 2% duty. The supplied tariff data records no anti-dumping or countervailing duty, suspension or attached import control for these lines. The heading's separate suspension for a specified automotive brake hose does not cover dredging hoses.
Give your broker the construction drawing, reinforcement materials and details of attached flanges or couplings to confirm the commodity code. For wider heading coverage, see the rubber steam hoses guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Dredging hoses reinforced only with metal, without fittings | 4009 21 00 00 | 2% | None |
| Dredging hoses reinforced only with metal, with fittings | 4009 22 00 90 | 2% | None |
| Dredging hoses reinforced only with textile, without fittings | 4009 31 00 90 | 2% | None |
| Dredging hoses reinforced only with textile, with fittings | 4009 32 00 90 | 2% | None |
| Dredging hoses with mixed or other reinforcement, without fittings | 4009 41 00 00 | 2% | None |
| Dredging hoses with mixed or other reinforcement, with fittings | 4009 42 00 90 | 2% | None |
Specify the slurry, suction duty and flange drawing
State whether the hose handles suction or discharge, the slurry composition, solids concentration, particle size and angularity, temperature and operating pressure. Agree vacuum resistance for suction service, bore, lining thickness, reinforcement, length, minimum bend radius and the installation's movement. For floating hoses, agree buoyancy and how the hose behaves when filled.
Approve a flange drawing covering drilling, face dimensions, material, corrosion protection and attachment to the hose. Ask for abrasion-test evidence for the proposed lining compound and pressure and vacuum test reports tied to the construction ordered. Agree acceptance criteria before production through testing and certification.
For supply in Great Britain, assess pressure-equipment scope and exclusions: the Pressure Equipment (Safety) Regulations apply above a maximum allowable pressure of 0.5 bar, subject to exclusions. Where they apply, importers must ensure that English instructions accompany the equipment. Ask the supplier to explain the classification for your intended installation.
REACH restrictions can limit, ban or set conditions on substances in articles. Ask the factory for the rubber compound's applicable UK REACH restriction assessment and supporting evidence.
Worked duty example
Illustrative example, not a quote: An illustrative batch of flanged rubber dredging hoses with textile and steel reinforcement under 4009 42 00 90, invoiced at £60,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £63,000. Duty at 2% is £1,260. Import VAT at 20% is charged on the customs value plus duty, £64,260, so it is £12,852. Import taxes total £14,112; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,260 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Construction: measure bore, length and lining thickness against the drawing; inspect a cut sample for reinforcement layout, exposed wire, voids and poor bonding.
Flanges: check drilling, face alignment, surface condition and attachment; trial-fit the specified mating flange and gasket.
Performance: match pressure, vacuum and abrasion reports to the batch and construction; check agreed test results for leakage, collapse and lining separation.
Arrival condition: inspect the bore and cover for cracks, blisters, flattening and transport damage; check batch identification, protected ends and supports that prevent sharp bends.

What goes wrong
A discharge hose selected for suction service can collapse. A lining chosen without the slurry's particle information can wear through prematurely. Poor bonding can let the lining separate, while mismatched flange drilling or distorted faces can prevent a sound connection.
A generic pressure report does not establish abrasion resistance or vacuum performance for your hose. Compare the delivered construction with the approved drawing and test evidence, and investigate exposed reinforcement, damaged flange faces or lining defects before installation.

Frequently asked questions
What is the UK import duty on rubber dredging hoses from China?
The relevant heading 4009 lines carry 2% duty in the supplied tariff data, with no anti-dumping or countervailing duty and no suspension for dredging hoses.
Which commodity code covers a steel-and-textile dredging hose?
Mixed reinforcement points to 4009 41 00 00 without fittings or 4009 42 00 90 with fittings. Confirm the actual construction and attached fittings with your broker.
Can I use a discharge hose on a dredger's suction line?
Specify suction service explicitly. Ask for vacuum-resistance evidence for the construction ordered and agree bending and installation conditions; a discharge-pressure report alone is insufficient.
Do pressure-equipment rules apply to dredging hoses?
Assess the installation and exclusions. The rules apply to pressure equipment above a maximum allowable pressure of 0.5 bar, subject to exclusions. Ask the supplier to explain the classification.
