Sourcing coated wallpaper base paper from China

Zero duty on mineral-coated base paper

Read from the UK Trade Tariff on 1 October 2026, heading 4810 covers paper and board coated with kaolin or other inorganic substances, with or without a binder and with no other coating. This guide concerns wallpaper base paper bought for further converting. See the coated paper and board guide for the wider heading.

The supplied tariff facts show 0% duty on goods from China, with no listed anti-dumping or countervailing duty, suspensions or attached import controls. The selected weight and brightness bands require 70 to 400 grams per square metre and brightness above 84 measured according to ISO 2470-1, excluding rolls suitable for web-fed presses.

The table gives candidate lines for other single-ply coated paper, rather than a classification for every wallpaper substrate. Give your broker the fibre composition, bleaching, mineral coating, grammage, brightness, reel format and intended use. Confirm the commodity code, including whether the paper belongs to a graphic-paper or kraft branch instead.

Specify the base paper for your wallpaper process

Specify the base furnish, virgin and recycled fibre content, mineral pigment, binder and coated face. Agree grammage, thickness, moisture, shade, surface strength and tolerances against an approved sample. State the intended printing, embossing or subsequent coating process, and distinguish converting stock from material supplied ready for wall application.

Run sample reels through the intended process. Check ink uptake, coating dust, surface picking, wet strength and dimensional change when the backing meets the intended paste. Agree reel width, diameter, core size, winding direction, splice marking and protective wrapping. Ask for a mill test certificate tied to each batch.

For virgin wood fibre, confirm with the relevant authority the timber due diligence requirements for the importer first placing the paper on the Great Britain market, including any checks on species and country of harvest. Confirm how recycled products and the virgin portion of mixed furnish are treated. Traders reselling timber products already on that market must keep supplier and trade-customer records.

Worked duty example

Illustrative example, not a quote: Illustrative trial consignment of bleached kaolin-coated wallpaper base paper in reels under 4810 99 10 80, invoiced at £6,700 free on board, with £3,500 of freight and insurance to the UK. The customs value is £10,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £10,200, so it is £2,040. 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 properties: compare conditioned samples from different reels with the agreed grammage, thickness, moisture and shade, and reconcile results with the batch certificate.

Coating and printing: check for streaks, pinholes, dust and picking, then print a trial with the intended inks and compare coverage and adhesion with the approved sample.

Wet performance: apply the intended paste to trial-converted samples and check expansion, curl, tearing and coating separation during handling and drying.

Reels and arrival: measure width and core fit, inspect winding and marked splices, and record crushed edges, damaged cores or damp wrapping before feeding reels into production.

What goes wrong

A smooth-looking sample can still dust or pick during printing. Uneven absorbency produces patchy colour, while moisture variation causes curl and unstable web tension. A changed fibre mix or binder can alter wet strength and expansion even when grammage matches the order.

Approve a converting trial using the intended inks, coatings and paste before accepting the production grade. Keep a retained sample and batch identity for comparison. Inspect reel protection before dispatch and document arrival damage promptly; agree checks using the quality inspection guide.
