Sourcing spun PPS yarn from China

UK duty on spun PPS yarn

Read from the UK Trade Tariff on 4 October 2026, heading 5509 covers synthetic staple-fibre yarn other than sewing thread, not put up for retail sale. For PPS yarn, distinguish single yarn from folded or cabled yarn and record the complete blend. The table gives candidate lines, rather than a classification based only on the supplier's product name.

All relevant lines carry 4% duty for goods from China. The supplied tariff snapshot records no anti-dumping or countervailing duty and no suspension. The table's lines have no attached import controls. Elsewhere in this heading, wool or fine animal-hair blend lines have CITES import and export controls. Importing CITES specimens requires a permit; for a PPS blend containing animal hair, confirm the species and applicable requirement with your customs broker.

Pure PPS yarn falls within the other synthetic staple-fibre categories; blends need closer checking against the 85% threshold and the named fibre categories. Confirm your commodity code using composition, construction and packaging details. For related yarn within the wider heading, see spun aramid yarn.

Specify PPS yarn for the actual process

Specify polyphenylene sulphide staple fibre, the blend by weight, yarn count, single or folded construction, twist direction, twist level, breaking force, elongation and evenness. Agree cone dimensions, net yarn weight, winding density and splice acceptance. Retain an approved sample and identify the fibre and spinning batches.

For filtration or other industrial weaving, describe the operating atmosphere, heat exposure and chemicals the finished fabric will encounter. Ask for tests on the supplied yarn and a woven trial under those conditions, rather than accepting a generic fibre brochure as performance evidence. Textile labels must show fibre content; check composition information against the tested blend.

Worked duty example

Illustrative example, not a quote: Illustrative trial order: 200 kg of single spun PPS yarn on cones under 5509 41 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

Identity: check laboratory fibre identification and blend results against the approved PPS sample and batch documents.

Yarn: check count, twist, breaking force, elongation, evenness and hairiness on cones from different cartons.

Packages: check net yarn weight, winding, damaged cones, contamination and batch separation on arrival.

Process trial: weave the intended construction and check yarn breaks, fabric uniformity and performance after the agreed heat and chemical exposure.

What goes wrong

A yarn described simply as PPS leaves the blend, staple construction and finish uncertain. Substituted fibres or an unapproved blend can change processing and finished-fabric performance. Count variation, excessive hairiness and weak joins can cause weaving stops; uneven winding can create unwinding tension problems.

Keep suspect batches separate and compare their test results with retained samples before production. Agree how the mill will investigate failures and replace rejected material. Use the quality inspection guide to organise sampling and reporting.
