Sourcing carbide planer knife blanks from China
Carbide planer knife blanks from China carry 0% UK duty when classified as unmounted cermet blanks under heading 8209. Confirm with HSE the applicable supplier duties concerning safety and adequate safe-use information for tools supplied for use at work. Agree grade and grinding allowance. Cambridge China Bridge sources carbide planer knife blanks.
Duty and classification for planer knife blanks
Read from the UK Trade Tariff on 4 October 2026, heading 8209 covers plates, sticks, tips and similar items for tools, unmounted, of cermets. This guide covers carbide blanks for making planer knives. The relevant “Other” line is 8209 00 80 00. The table shows blank variants sharing that line, rather than separate tariff subdivisions.
The supplied tariff record lists 0% duty for goods from China across the heading, with no anti-dumping or countervailing measures, suspensions or attached import controls. The zero rate concerns customs duty; import VAT is separate. See the import duty and VAT guide.
Confirm the material, supplied condition and degree of finishing through the commodity code guide. Describe whether the shipment contains unmounted strips, ground blanks or complete knives, and provide drawings to your customs broker. For related blanks across the wider heading, see the cemented carbide rod blanks guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Unground carbide planer knife strip blanks | 8209 00 80 00 | 0% | None |
Specify the carbide grade and grinding allowance
Send drawings showing blank length, width, thickness, straightness, flatness and acceptance tolerances. Distinguish the delivered blank dimensions from the finished knife dimensions. State which faces arrive ground, which remain as sintered, and the allowance reserved for thickness grinding, edge grinding and profiling.
Agree the carbide grade, binder composition, hardness and toughness data, intended timber or board material, and subsequent manufacturing process. For strips intended for brazing, describe the steel backing and joining process. Approve samples after your own grinding and representative cutting trials, rather than accepting a grade name alone.
Tools for use at work count as work equipment. Confirm with HSE the applicable supplier duties concerning safety and adequate safe-use information. Request information on intended use, further processing and recognising damage, and make the unfinished condition clear.
Worked duty example
Illustrative example, not a quote: Illustrative mixed batch of carbide planer knife strip blanks for a small tooling business under 8209 00 80 00, invoiced at £30,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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
Dimensions: measure length, width and thickness against the blank drawing; check flatness, straightness and the remaining grinding allowance.
Material: match batch identification and material records to the agreed grade; arrange sample hardness and composition checks where these form part of acceptance.
Condition: inspect corners, edges and ground faces for chips, cracks and grinding damage; check that separate supports prevent blanks striking each other in transit.
Processing trial: grind sample blanks using your intended process, then assess finished knife fit, cutting finish and edge damage on representative material. Agree sampling and acceptance through the inspection guide.

What goes wrong
A blank can meet its nominal dimensions yet leave too little stock to remove bow or surface defects. Uneven grinding allowance causes extra machining or rejection. Confusing blank dimensions with finished knife dimensions can leave the knife undersized after sharpening. Confirm both drawings before production.
An unsuitable grade may wear quickly or chip during interrupted cutting. Cracks or damaged corners can become visible only after grinding. Mixed batches make failures difficult to trace, while loose packing damages otherwise usable blanks. Retain approved samples and compare repeat batches after the same processing and cutting trial.

Frequently asked questions
What is the UK import duty on carbide planer knife blanks from China?
The supplied tariff record gives 0% duty for unmounted carbide blanks under 8209 00 80 00, with no anti-dumping or countervailing measures. Import VAT is separate.
Does this guide cover finished planer knives?
It covers unmounted carbide blanks. A finished knife or a carbide strip already joined to a backing needs its supplied condition assessed separately before you use the blank code.
What should I specify when ordering carbide planer knife blanks?
Provide blank and finished knife drawings, grade, binder composition, tolerances, ground faces and grinding allowance. Describe the material to be cut and any brazing process.
How do I check a Chinese factory’s planer knife blanks?
Check dimensions, flatness, straightness, material records and damage. Grind samples into your intended knives, then compare cutting finish and edge damage on representative material.
