Sourcing lever-arch mechanisms from China
Metal lever-arch file mechanisms from China carry 2% UK duty, with no rate variation across the comparison lines shown. Confirm with your local Trading Standards service the safety requirements for mechanisms incorporated into consumer files. Specify arch spacing, lever action and mounting holes. Cambridge China Bridge sources metal lever-arch file mechanisms.

Duty and classification for lever-arch mechanisms
Read from the UK Trade Tariff on 30 September 2026, heading 8305 covers base-metal binder and file fittings, similar office articles and staples in strips. Metal lever-arch mechanisms with arched elements on a back plate and an opening trigger are described under 8305 10 00 50.
The supplied tariff record shows 2% duty for goods from China under the lever-arch line and every comparison line in the table. It records no anti-dumping or countervailing duty, suspension or attached import control for these lines.
The other table entries are comparison categories for different fittings or separately supplied parts, rather than alternative codes for a complete lever-arch mechanism. Send drawings and photographs to your customs broker to confirm the commodity code. For the wider heading, see our metal file prong mechanisms guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Metal lever-arch file mechanisms | 8305 10 00 50 | 2% | None |
| Other loose-leaf binder or file fittings | 8305 10 00 99 | 2% | None |
| Other office articles, including separately supplied parts | 8305 90 00 00 | 2% | None |
| Other ring binder mechanisms, for comparison | 8305 10 00 49 | 2% | None |
Specify the mechanism against the finished file
Specify arch spacing, arch height, usable sheet capacity, back-plate dimensions, steel thickness and fixing-hole positions. Provide the cover-board thickness and agree the rivet specification. State whether the compressor bar is included, how it locks and how the lever should open and close. Approve a sample fitted to the intended file cover.
Agree the plating, corrosion test conditions and acceptable operating force. For mechanisms incorporated into consumer files in Great Britain, confirm with your local Trading Standards service how the General Product Safety Regulations 2005 apply, including safety in normal or reasonably foreseeable use. Assess sharp edges, burrs and finger-trapping risks on the assembled file.
Worked duty example
Illustrative example, not a quote: 2,000 metal lever-arch file mechanisms; illustrative order, FOB and freight values under 8305 10 00 50, invoiced at £2,500 free on board, with £600 of freight and insurance to the UK. The customs value is £3,100. Duty at 2% is £62. Import VAT at 20% is charged on the customs value plus duty, £3,162, so it is £632.40. Import taxes total £694.40; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £62 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Fit: measure arch spacing, back-plate dimensions and fixing-hole positions against the approved drawing; fit sampled mechanisms to the intended cover board.
Movement: repeatedly operate the lever and compressor bar; check that arch ends meet without gaps or overlap and that the closure stays secure with sheets loaded.
Finish: check arch ends and plate edges for burrs, plating damage and rust; compare corrosion test reports with the agreed finish and conditions.
Packing: check that arches and levers are protected from bending and that cartons identify the agreed model. Compare arrival samples with the retained sample and use the quality inspection guide.

What goes wrong
Misaligned arch ends catch or tear sheets. A mechanism can look correct while its fixing holes or rivets do not suit the cover board. A weak closure opens under load, while a stiff lever makes filing difficult. A compressor bar that slips lets papers move inside the file.
Thin or damaged plating can rust in damp storage, and loose packing can bend arches during transport. Approve the fitted assembly, record the agreed dimensions and operating force, and compare production and arrival samples with it.

Frequently asked questions
What is the UK import duty on metal lever-arch mechanisms from China?
The supplied tariff record shows 2% under 8305 10 00 50, with no anti-dumping or countervailing duty, suspension or attached import control recorded.
Which measurements should I send to the factory?
Send arch spacing and height, sheet capacity, back-plate dimensions, steel thickness, fixing-hole positions and cover-board thickness. Specify rivets, plating and the compressor bar.
How do I check a lever-arch mechanism sample?
Fit it to the intended cover board, load it with sheets and operate the lever and compressor bar. Check arch alignment, secure closure, rivet fit, burrs and finger-trapping risks.
Which safety rule applies to consumer files in Great Britain?
The General Product Safety Regulations 2005 cover products intended for, or reasonably likely to be used by, consumers. Confirm the applicable safety requirements with your local Trading Standards service. Assess the mechanism as fitted to the finished file.
