Industrial Grade Ammonium Chloride Crystals
Pure ammonium chloride (NH4Cl) in crystalline form, used primarily in industrial applications such as battery manufacturing and metal fluxing. It falls under HTS 2827.10.00.00 as a chemically defined inorganic compound of ammonium chloride, explicitly covered in Chapter 28 for chlorides. This subheading distinguishes it from other metal chlorides.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing nitrogen suitable for fertilizer use
Fertilizer-grade ammonium chloride with added nutrients falls under Chapter 31 as mineral/chemical fertilizers, per Chapter 28 exclusion notes.
If mixed with organic stabilizers or sold as a formulated mixture
Mixtures not purely chemically defined ammonium chloride are classified as chemical preparations in 3824, outside pure inorganic compounds of Chapter 28.
If in complex salt form with other inorganic bases
Double or complex salts of chlorides are directed to heading 2842 by Chapter notes, rather than simple ammonium chloride.

Import Tips & Compliance
• Verify purity levels (>99%) via certificate of analysis to meet chemically defined criteria; ensure SDS includes UN number 3077 for hazardous classification
• Avoid misdeclaration as fertilizer-grade to prevent reclassification under Chapter 31
