Sourcing abrasive backing paper from China
Abrasive backing paper within heading 4811 carries 0% UK duty from China across the listed treatments. Specify the paper before abrasive grain is applied, and confirm its coating and fibre source. Confirm with the relevant authority any timber due diligence requirements before placing virgin-fibre paper on the GB market. Cambridge China Bridge sources abrasive backing paper.
Duty on treated abrasive backing paper
Heading 4811 covers coated, impregnated and otherwise treated paper in rolls or rectangular sheets. This guide concerns backing paper supplied for abrasive manufacture before grit is applied. The selected lines are classification candidates according to the actual treatment, not interchangeable codes for anything sold as abrasive backing paper.
Read from the UK Trade Tariff on 30 September 2026, all lines in the supplied heading data carried 0% duty for goods from China. The data records no anti-dumping or countervailing measures, suspensions or attached import controls. This does not remove the timber due diligence obligations for paper within scope.
Confirm the commodity code using the coating composition, whether it is adhesive, bleaching, grammage and supplied format. For the finished abrasive product, see the abrasive sanding belts guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Plastic-treated bleached backing paper, over 150 g/m², excluding adhesives | 4811 51 00 00 | 0% | None |
| Other plastic-coated or impregnated backing paper, excluding adhesives | 4811 59 00 90 | 0% | None |
| Gummed or adhesive backing paper, other than self-adhesive | 4811 49 00 00 | 0% | None |
| Other treated backing paper | 4811 90 00 90 | 0% | None |
Specify the backing and resin treatment
State the intended abrasive product and whether it will be used wet or dry. Specify fibre composition, grammage and tolerance, thickness, machine-direction and cross-direction tensile strength, stretch, tear resistance, moisture and surface absorbency. Agree the test methods and sample conditioning with the mill.
Identify the impregnation resin, surface treatment and treated faces. Agree resin pick-up, flexibility, resistance to your curing process and compatibility with your abrasive binder. Specify reel width, core, winding direction and splice marking. Approve a sample through your own coating and curing process before accepting bulk production.
Confirm with the relevant authority whether the paper falls within the UK Timber Regulations, what due diligence is needed and which business is responsible before first placement on the GB market. Obtain the pulp source, tree species and country of harvest. Confirm how bamboo-based or recovered products are treated; establish the actual fibre composition rather than relying on a recycled label.
Worked duty example
Illustrative example, not a quote: Illustrative order: 12 tonnes of resin-impregnated backing paper in reels under 4811 59 00 90, invoiced at £14,000 free on board, with £1,800 of freight and insurance to the UK. The customs value is £15,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £15,800, so it is £3,160. 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
Paper: check grammage, thickness, moisture and directional strength against the agreed specification using samples across the reel.
Treatment: check uniform impregnation, surface streaks, resin-rich patches, brittleness and binder adhesion after a trial cure.
Reels: check width, winding, marked splices, edge damage, core condition and moisture-resistant wrapping before dispatch and on arrival.
Records: match reel identification to mill test results, approved samples and fibre-source information.

What goes wrong
Backing can pass a basic paper test but split, curl or become brittle during abrasive coating and curing. Uneven resin treatment changes binder absorption, while unsuitable fibre or poor directional strength causes tearing during conversion. Assess the backing in your process rather than approving it by colour or feel.
Moisture pick-up, crushed cores and damaged edges can make reels difficult to unwind. Record arrival defects before processing, retain labelled samples and compare affected reels with the approved production sample. Agree acceptance criteria and remedies in the purchase specification.

Frequently asked questions
What is the UK import duty on abrasive backing paper from China?
The supplied tariff data records 0% duty across heading 4811 for goods from China, with no anti-dumping or countervailing measures. Confirm the line from the paper's treatment and specification.
Which commodity code covers resin-impregnated backing paper?
4811 59 00 90 is a candidate for other plastic-impregnated paper excluding adhesives. Bleached paper over 150 g/m² has a separate line. Confirm the resin, bleaching and grammage before choosing.
Do timber rules apply to abrasive backing paper?
Confirm with the relevant authority whether timber due diligence is needed before first placement on the GB market. Check how the rules apply to the actual virgin-fibre, bamboo-based or recovered product.
What should I test before ordering backing paper?
Check directional strength, flexibility, moisture and resin uniformity, then run the sample through your abrasive coating and curing process. Check binder adhesion, curl and tearing after conversion.
