Sourcing urea ammonium nitrate from China

6% base duty, suspended to 0%

Read from the UK Trade Tariff on 3 October 2026, heading 3102 covers mineral or chemical nitrogenous fertilisers. Urea and ammonium nitrate mixed in aqueous or ammoniacal solution fall under 3102 80 00 00. This guide covers that solution family; see urea and nitrogen fertilisers for the wider heading.

The supplied record lists 6% third-country duty and an autonomous tariff suspension of 0.00 %. It records no anti-dumping or countervailing duty, suspension footnotes or attached import controls for this line. Have your broker confirm the suspension claim at entry. The absence of an attached tariff control does not settle chemical supply obligations.

Give your broker the complete formulation, nutrient analysis and packaging details to confirm the commodity code. Describe the mixture explicitly on the invoice rather than calling it only liquid fertiliser.

Specify the nitrogen forms and liquid behaviour

Specify total nitrogen and its urea, ammonium and nitrate fractions, with agreed tolerances and analytical methods. State whether the carrier is water or an ammoniacal solution. Agree density at a stated temperature, acidity or alkalinity, insoluble matter and crystallisation behaviour at the temperatures expected during shipment and storage.

Ask for a batch analysis, safety data sheet and proposed delivery label before approving the shipment. Confirm the applicable fertiliser type and nutrient-content labelling requirements with the relevant UK authority. Agree tank material, previous-cargo cleaning evidence, seals, valve connections and unloading arrangements with the receiving site.

Under UK REACH, the mixture itself is not registered, but its constituent substances require registration when aggregated imports of a substance reach 1 tonne or more per year. Check the registration position before ordering. Chemical classification and labelling must be handled by someone with scientific competence, and labels and packaging must be correct before sale in Great Britain.

Worked duty example

Illustrative example, not a quote: Illustrative order: 25 tonnes of urea ammonium nitrate solution in a tank container under 3102 80 00 00, invoiced at £9,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £11,500. Duty at 6% is £690. Import VAT at 20% is charged on the customs value plus duty, £12,190, so it is £2,438. Import taxes total £3,128; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £690 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the tank seals, batch reference, formulation and delivery documents to the purchase order.

Analysis: use representative samples to check total nitrogen and the agreed nitrogen fractions, density and acidity or alkalinity against the contract.

Liquid condition: check for crystals, sediment or separation and compare the observed temperature with the agreed handling conditions.

Tank and labels: check for leaks, damaged valves and contamination, and match nutrient declarations to the batch analysis. Plan sampling with the quality inspection guide.

What goes wrong

A total-nitrogen result can hide the wrong balance of nitrogen forms. Dilution, residue from a previous cargo or a formulation change can leave the delivered solution different from the approved sample. Crystals or sediment can obstruct unloading and application equipment.

Set acceptance criteria for the delivered liquid, retain sealed batch samples and agree how a disputed load will be isolated before unloading. Treat a supplier's generic analysis as a starting document, then compare independent batch results and the receiving site's handling needs.
