HS Code for Ammonia solution

Ammonia solution, commonly known as ammonium hydroxide or ammonia water, is precisely classified under Harmonized System (HS) code 281420. This classification is situated within Chapter 28 of the HS nomenclature, which is exclusively dedicated to inorganic chemicals. The specific description for 281420, "Ammonia; in aqueous solution," directly and accurately identifies ammonia that has been dissolved in water. This precise categorization is crucial for distinguishing products consisting of ammonia in a water-based medium from other forms of ammonia or related chemical compounds. The fundamental chemical nature of ammonia as an inorganic compound and its presentation as an aqueous solution are the primary and definitive criteria for its classification under this specific HS code. This ensures consistent global trade classification for this widely used chemical.

Products Included

• Aqueous ammonia
• Ammonium hydroxide
• Ammonia water
• Diluted ammonia solution
• Household ammonia (when primarily ammonia in water)

Common Misclassification

A frequent source of misclassification for ammonia solution involves HS code 281410, which is designated for "Ammonia; anhydrous." Anhydrous ammonia refers to pure ammonia gas, which is not dissolved in water and is typically handled as a compressed gas. The distinction between these two codes is critical: 281410 applies to the un-dissolved gaseous form, while 281420 is specifically reserved for the aqueous solution. Another potential misclassification might occur with broader or less specific categories, such as general inorganic chemical codes, but 281420 provides the most accurate and specific classification for ammonia in its dissolved, aqueous form.

FAQ

What is the HS code for Ammonia solution?

The HS code for ammonia solution is 281420. This code specifically covers "Ammonia; in aqueous solution," accurately reflecting its chemical composition and form.

What is the primary difference between anhydrous ammonia and ammonia solution?

The primary difference lies in their physical state and composition. Anhydrous ammonia (HS 281410) is pure ammonia gas, typically stored under pressure. Ammonia solution (HS 281420) is ammonia gas dissolved in water, forming ammonium hydroxide, and is a liquid at ambient conditions.
