Sourcing paper security envelopes from China

UK duty on paper security envelopes

Read from the UK Trade Tariff on 1 October 2026, paper envelopes under 4817 10 00 00 carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing measures, suspensions or attached import controls for this line.

Heading 4817 covers paper or paperboard envelopes, correspondence cards and assorted stationery containers. The table shows security-envelope variants sharing the envelope commodity line. See the wider envelope guide for other products within the heading.

Confirm the commodity code using the finished envelope's materials and construction, particularly if the supplier proposes plastic or padded alternatives. Even where no tariff controls are attached, confirm with OPSS or your customs broker whether timber due-diligence obligations apply to the paper.

Opacity, security print and sealing

Specify finished dimensions, paper weight, internal security pattern, window position and flap construction. Approve a sample containing your actual document layout. Check whether names, figures or other confidential text can be read through the paper under agreed lighting. Agree acceptance criteria against that sample rather than accepting a supplier's description of 'security paper'.

Choose gummed, self-seal or peel-and-seal closure and agree storage conditions for adhesive testing. Distinguish concealment from evidence of opening: an internal pattern helps obscure contents, but any promised tamper evidence needs a separate opening test. Trial samples through your inserting equipment before approving production.

For virgin-fibre paper first placed on the Great Britain market, confirm timber due-diligence obligations with OPSS or your customs broker. Obtain the pulp source, species and country of harvest; confirm whether any exclusions apply to bamboo-based and recovered products rather than relying on the wider guide alone. Where envelopes serve as packaging, check whether your business is obligated under packaging extended producer responsibility.

Worked duty example

Illustrative example, not a quote: Illustrative small-business stock order of peel-and-seal paper security envelopes under 4817 10 00 00, invoiced at £24,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £26,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £26,500, so it is £5,300. 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

Opacity: insert the approved test document and compare visibility with the signed sample, including folds, seams and areas beside the window.

Seals: check flap coverage, adhesive continuity and liner release; compare closure and opening behaviour after agreed warm and humid storage tests.

Dimensions and print: measure the envelope and window against the drawing, check internal pattern coverage and run samples through the intended inserting equipment.

Arrival condition: inspect for damp paper, stuck flaps, curled edges and crushed cartons; count sampled cartons and retain examples of defects. Use the inspection guide to agree checks before shipment.

What goes wrong

A dark internal pattern can look convincing while thin paper still reveals the contents. Gaps in the pattern, poor window placement or translucent seams can expose confidential text. Compare production samples containing your documents with the approved sample, rather than inspecting empty envelopes alone.

Adhesive can lose tack during storage, while humidity can cause flaps to stick before use. Incorrect dimensions or curled edges can jam inserting equipment. Record paper, ink and adhesive specifications so a repeat order can be checked for substitutions.
