Ammonium Chloride: Fertiliser Grade vs Industrial Grade — What Importers Must Know

Why the grade decides everything

Ammonium chloride (NH₄Cl) is a single chemical compound, but in international trade it is not a single product. The grade — fertiliser use versus non-fertiliser (industrial) use — determines the customs classification, whether mandatory export inspection applies, which packing the buyer expects, and which destinations will accept the shipment.

For a buyer, this matters because a quotation that does not state the grade is not comparable to the others in their inbox. For a supplier, declaring the wrong grade creates clearance risk that no price advantage can offset.

The two entries in the Chinese export catalogue

China's customs commodity catalogue lists ammonium chloride under two separate entries: one for fertiliser use and one for non-fertiliser use. They are classified differently, and the fertiliser entry sits in the import/export commodity inspection catalogue — meaning shipments declared under it are subject to export commodity inspection.

This is why experienced exporters are explicit about the intended use rather than treating NH₄Cl as one commodity, and why a responsible supplier will ask the buyer what the material will be used for before confirming a price.

How to specify NH₄Cl on an enquiry

Send these five things and any supplier can quote accurately on the first reply:

• Intended use — fertiliser, battery, electroplating, fluxes, water treatment or other
• Purity requirement — for example NH₄Cl ≥99.5% for industrial use
• Form — powder or crystalline
• Packing — 25 kg, 50 kg or jumbo bag, and whether private label is needed
• Quantity and destination port, with FOB or CIF as the required term

Our position

We supply industrial (non-fertiliser) grade ammonium chloride and declare it under the corresponding non-fertiliser classification, kept as a separate product line from fertiliser-grade material. If your application is agricultural, tell us up front — that shifts the product into a different regulatory track and we will confirm feasibility before quoting.

Customs classifications, inspection catalogues and export-control measures change. Treat the classification shown on any supplier's website as a starting point and confirm the current requirement with your customs broker or freight forwarder for your specific product name and declared use.
