Sourcing Isobutyronitrile from China
Isobutyronitrile's candidate tariff line carries 0% duty from China; rates elsewhere in heading 2926 run from 0% to 6%. Confirm the substance and code, arrange competent hazard classification and correct labelling, and check UK REACH registration responsibilities. Cambridge China Bridge sources isobutyronitrile.
Isobutyronitrile: check the residual 0% line
Read from the UK Trade Tariff on 1 October 2026, heading 2926 covers nitrile-function compounds. Isobutyronitrile is not separately named in the supplied lines. The residual code 2926 90 70 90 is the candidate to confirm and shows 0% duty for goods from China, with no anti-dumping or countervailing duty recorded.
The residual line lists autonomous and authorised-use suspensions. Its named autonomous suspension does not list isobutyronitrile, so do not claim that relief merely because another nitrile qualifies. The tariff also attaches export controls on dangerous chemicals and waste. Confirm their relevance with your customs broker. HSE states that there are no prior informed consent notification obligations for imports. If material is waste shipped under notification controls, the relevant authorities must consent before shipment.
Confirm the exact substance, composition and commodity code before dispatch. The table repeats the candidate residual line for purchasing specifications, rather than presenting separate official grades. For the wider heading, see the propionitrile guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Isobutyronitrile for laboratory synthesis | 2926 90 70 90 | 0% | None |
Specify identity, assay and water content
Write isobutyronitrile explicitly on the purchase specification and require the supplier's chemical identity and composition details. Avoid accepting a quotation that says only butyronitrile. Agree the assay method, water test, impurity reporting and acceptance limits before approving a sample.
Ask for an analysis certificate for the production batch, with results rather than a generic specification sheet. Compare the sample in your intended synthesis or process before accepting bulk material. Agree container material, closure compatibility and arrangements for receiving and sampling the chemical.
UK REACH registration generally applies when a business imports a substance into Great Britain at or above 1 tonne per year; registration is per substance and legal entity. Confirm your registration responsibilities before ordering. Classification and labelling must be carried out by someone scientifically competent, and supply-chain businesses are responsible for correct labelling and packaging before market placement.
Worked duty example
Illustrative example, not a quote: Illustrative order: 25 kg of isobutyronitrile for process trials under 2926 90 70 90, invoiced at £2,500 free on board, with £2,000 of freight and insurance to the UK. The customs value is £4,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,500, so it is £900. 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
Identity: match the chemical identity across the order, container labels, analysis certificate and English safety data sheet.
Analysis: compare batch assay, water content and impurity results against the agreed specification using a suitably equipped laboratory.
Containers: check seals, closures, damage, leakage and batch identification without opening containers in an unsuitable receiving area.
Documents: reconcile delivered quantities and batch references with the packing list and retain photographs and test results. Use a written inspection brief.

What goes wrong
A shortened chemical name can conceal a different substance. A generic analysis certificate can also leave water content or relevant impurities untested. Treat these as checks to resolve before shipment, rather than assuming that a passing assay proves suitability for your process.
Hold a batch with mismatched identity, unexplained test results or leaking containers pending assessment by your chemical adviser. Resolve replacement and testing responsibilities in the purchase agreement. Do not copy another nitrile's suspension claim or packaging information into this order.

Frequently asked questions
What is the UK import duty on isobutyronitrile from China?
The supplied tariff snapshot shows 0% on candidate residual code 2926 90 70 90, with no anti-dumping or countervailing duty recorded. Confirm classification for your exact product.
Do I need UK REACH registration for isobutyronitrile?
Registration generally applies at or above 1 tonne per year imported into Great Britain. Check your business's registration responsibilities and any applicable representative arrangements before ordering.
What should an isobutyronitrile analysis certificate show?
The delivered batch reference, chemical identity, assay method and result, water result and agreed impurity results. A generic specification sheet does not establish the delivered batch's quality.
Can I use the butyronitrile tariff line for isobutyronitrile?
Do not assume so. The supplied tariff separately names butyronitrile. Confirm isobutyronitrile's exact identity and classification with your customs broker.
