Sourcing drip irrigation tubing from China
The selected drip irrigation tubing and fitting lines carry 6% UK duty from China. Check REACH restrictions on the material and agree wall thickness, emitter spacing and flow at the intended pressure before ordering. Cambridge China Bridge sources drip irrigation tubing.
UK duty on drip irrigation tubing
Heading 3917 covers plastic tubes, pipes, hoses and their fittings. For drip irrigation, distinguish plain supply tubing from tubing with emitters, tubing supplied with fittings and reinforced hose. The rows are classification candidates, rather than a code assignment for every dripline design.
Read from the UK Trade Tariff on 4 October 2026, the selected lines carried 6% duty for goods from China, with no anti-dumping or countervailing duty, suspension or attached import control. Elsewhere in this heading, a suspension covers specified car fuel-hose connectors and veterinary control attaches to hardened-protein sausage casings. These descriptions are outside this guide's product scope; importers of those casings should confirm the control with their customs broker.
Send your customs broker the material specification, cross-section, emitter construction and details of supplied fittings to confirm the commodity code. For the wider product family, see plastic pipes and building materials.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other unreinforced flexible plastic tubing, without fittings | 3917 32 00 90 | 6% | None |
| Other unreinforced flexible plastic tubing, with fittings | 3917 33 00 90 | 6% | None |
| Other flexible plastic tubing, including reinforced types | 3917 39 00 99 | 6% | None |
| Other plastic tube fittings, including irrigation connectors | 3917 40 00 99 | 6% | None |
Specify the tube and emitter together
State whether you need plain supply tube, drip tape or round tubing with integrated emitters. Fix the resin, recycled content, outside diameter, wall thickness, coil length and dimensional tolerances. For emitters, specify spacing, flow at the agreed operating pressure, pressure-compensating behaviour, filtration needs and intended lateral length.
Agree connector dimensions, pull-out resistance, flushing arrangements and evidence for sunlight-resistance claims. Test the proposed tubing with your actual connectors and water source. REACH restrictions can limit, ban or set conditions on substances being placed on the market or used; ask for material information and assess applicable restrictions before buying.
For a public-water connection in England or Wales, confirm water-fittings compliance and the proposed backflow arrangement with the local water company before selecting the installation components. Government guidance identifies the water-fittings regulations as setting requirements and directs compliance questions to the local water company.
Worked duty example
Illustrative example, not a quote: Illustrative order: 20 coils of plain drip irrigation supply tubing under 3917 32 00 90, invoiced at £2,400 free on board, with £1,500 of freight and insurance to the UK. The customs value is £3,900. Duty at 6% is £234. Import VAT at 20% is charged on the customs value plus duty, £4,134, so it is £826.80. Import taxes total £1,060.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £234 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Dimensions: measure diameter, wall thickness, emitter spacing and sampled coil length against the order.
Flow: run sampled lengths at the agreed pressure and compare discharge along the line, checking blocked or leaking emitters.
Connections: assemble the actual fittings and check leakage, pull-out and tube damage at the agreed operating conditions.
Packing: check coil counts, batch identification, crushed turns and protected coil ends against the packing list.
What goes wrong
Thin or uneven walls can split at connectors, while flattened coils kink during installation. Wrong emitter spacing changes the watering pattern. Poor emitter bonding causes leaks, and contamination inside the tube can obstruct the flow path.
A sample tested with clean water and a short lateral may hide problems with your intended water source and layout. Keep an approved sample and agree the flow-test method before production. Use the same checks on arrival; see quality inspection explained.

Frequently asked questions
What is the UK import duty on drip irrigation tubing from China?
The selected tubing and plastic fitting lines carry 6% duty from China in the supplied tariff snapshot, with no trade remedy or suspension on those lines. Confirm the code for your exact construction.
Which commodity code covers drip irrigation tubing?
3917 32 00 90 is a candidate for unreinforced flexible plastic tubing without fittings. Supplied fittings, reinforcement and integrated emitter construction need checking before assigning the code.
What should I specify for drip tape?
Fix resin, wall thickness, diameter, coil length, emitter spacing and flow at the agreed pressure. Include filtration needs, intended lateral length and compatibility with your connectors.
How do I check drip irrigation tubing before accepting it?
Measure sampled coils, run a flow test at the agreed pressure, check emitter leakage and fit the actual connectors. Compare the results with the approved sample and written tolerances.
