Sourcing covered rubber thread from China

4% duty on textile-covered rubber thread

Read from the UK Trade Tariff on 21 November 2026, textile-covered rubber thread and cord under 5604 10 00 00 carried 4% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspension or attached import control for this line.

Heading 5604 also covers certain textile yarns and strips impregnated, coated, covered or sheathed with rubber or plastics. The table shows product variants sharing the textile-covered rubber thread code. See the elastic cord and rubber thread guide for the wider heading.

Confirm the rubber core and textile covering before choosing the commodity code. Flat woven or knitted elastic is classified as narrow fabric under heading 5806. A supplier's description of 'elastic thread' alone does not establish its construction.

Specify the rubber core and textile covering

State the core material, covering fibre, finished thickness, colour, spool length and permitted joins. Agree elongation under a stated load, recovery after repeated stretching and the washing conditions the finished garment will encounter. Keep an approved sample and trial the thread in the intended sewing process.

For rubber or plastic parts in direct and prolonged skin contact, UK REACH restricts specified polycyclic aromatic hydrocarbons. Ask for relevant chemical test results for the material supplied.

Worked duty example

Illustrative example, not a quote: Illustrative order: 5 tonnes of textile-covered rubber thread on spools under 5604 10 00 00, invoiced at £16,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £17,200. Duty at 4% is £688. Import VAT at 20% is charged on the customs value plus duty, £17,888, so it is £3,577.60. Import taxes total £4,265.60; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £688 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Stretch and recovery: sample several spools, repeat stretching under the agreed load and compare residual extension with the approved sample.

Covering: inspect relaxed and stretched thread for gaps, fraying, loose wraps and exposed or broken rubber cores.

Length and winding: measure sampled spool lengths, check joins against the order and trial unwinding for tangles or uneven tension.

Colour and ageing: check colour transfer onto the intended fabric, then repeat recovery checks after the agreed washing and heat exposure. Use the quality inspection guide to prepare the inspection brief.

What goes wrong

Thread may stretch initially but fail to recover after sewing or washing. A covering that looks intact at rest can open under tension, exposing the rubber. Uneven winding causes feed problems, short spools reduce usable output, and dark coverings can stain pale fabric.

Match the bulk thread to the approved construction and test it in the intended garment before accepting it. Investigate core breakage and covering movement separately: changing sewing tension cannot repair degraded rubber.
