Sourcing N-butyronitrile from China
N-butyronitrile from China carries a standard UK duty of 6%, with a qualifying suspension to 0%. Great Britain importers must arrange competent chemical classification and correct labelling and packaging before sale, and check UK REACH registration coverage. Cambridge China Bridge sources N-butyronitrile.
N-butyronitrile duty and suspension
Read from the UK Trade Tariff on 1 October 2026, heading 2926 covers nitrile-function compounds. N-butyronitrile, chemical identity 109-74-0, is listed under 2926 90 70 89. Its standard duty for goods from China is 6%, with an autonomous suspension to 0%. The supplied record lists no anti-dumping or countervailing duty. The table shows purchasing uses of the same substance under the same tariff line.
The recorded suspension excludes mixtures, preparations and products containing different components. The tariff also attaches export controls for dangerous chemicals and waste. Ask your customs broker to confirm whether either control affects the proposed transaction. For chemicals on the applicable dangerous-chemical list, official guidance says imports into Great Britain have no prior informed consent notification obligation, but annual quantity reporting applies.
Confirm the substance identity, composition and suspension eligibility with your broker using our commodity-code guide. A blend needs its own classification assessment. See the propionitrile guide for the wider heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| N-butyronitrile for synthesis | 2926 90 70 89 | 6% | None |
Specify identity, water and impurity profile
Put N-butyronitrile and chemical identity 109-74-0 on the enquiry, purchase order and batch certificate. Ask the producer to confirm the structure so that an isomer or another nitrile is not substituted. Agree assay, water content, individual impurities, appearance and analytical methods against your process needs. Request actual batch results and a chromatogram rather than a generic specification sheet.
Before importing into Great Britain, check UK REACH coverage. Importing a substance at or above 1 tonne annually requires registration, subject to the applicable coverage arrangements; verify any supplier-appointed only representative. Chemical classification and labelling require scientific competence, and the supply chain must ensure correct labels and packaging before market placement. Obtain the English safety data sheet before shipment and confirm with HSE the applicable language, timing and free-provision requirements.
Worked duty example
Illustrative example, not a quote: Illustrative 1 tonne batch in sealed drums under 2926 90 70 89, invoiced at £3,500 free on board, with £2,000 of freight and insurance to the UK. The customs value is £5,500. Duty at 6% is £330. Import VAT at 20% is charged on the customs value plus duty, £5,830, so it is £1,166. Import taxes total £1,496; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £330 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the purchase order, drum labels, safety data sheet and batch certificate to N-butyronitrile and 109-74-0.
Analysis: compare the delivered batch's assay, water and impurity results with the agreed methods and limits; investigate unexplained chromatogram peaks.
Packaging: inspect seals, closures, leaks and damage on arrival; reconcile batch references and quantities with the packing list.
Documents: check English safety information, classification, labels and packaging with a competent chemical adviser; ask the carrier to review transport details before collection.

What goes wrong
Watch for an incorrect chemical identity, a certificate covering a different batch, or purity reported without water and impurity results. A headline assay alone does not establish suitability for your reaction. Agree how samples will be taken and retained, and test the incoming batch against the purchase specification.
Resolve leaking closures, conflicting labels and unexplained analytical results before releasing the material into production or resale. Keep the supplier's batch evidence with the receiving inspection record. Our inspection guide explains how to turn agreed checks into an inspection brief.

Frequently asked questions
What is the UK import duty on N-butyronitrile from China?
The standard duty under 2926 90 70 89 is 6%, with an autonomous suspension to 0% for qualifying material. The recorded suspension excludes mixtures and preparations. No trade remedy is listed.
Do I need UK REACH registration for N-butyronitrile?
At or above 1 tonne annually into Great Britain, check registration coverage before importing. Verify whether your registration or a supplier-appointed only representative covers the substance and your imports.
What should an N-butyronitrile batch certificate show?
Ask for the chemical identity, batch reference, actual assay, water and impurity results, and the analytical methods. Match these to the purchase specification and delivered drum labels.
Can I use the N-butyronitrile code for a solvent blend?
Do not assume so. Give your broker the full composition for classification. The recorded N-butyronitrile suspension excludes mixtures, preparations and products containing different components.
