Industrial Grade Anhydrous Ammonia
Pure anhydrous ammonia (NH3) in liquid form under pressure, used primarily as a raw material in the production of fertilizers and chemicals. It falls under HTS 2814.10.00.00 as it is chemically defined anhydrous ammonia, distinct from aqueous solutions. This product is essential for large-scale industrial synthesis processes.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing more than 10% but not more than 50% ammonia by weight
Aqueous ammonia solutions with specific concentrations fall under the aqueous subheading rather than anhydrous.
If when imported as urea fertilizer precursor in fixed mixtures
Mixtures of ammonia with other substances for fertilizer use are classified in Chapter 31 as fertilizers, not pure chemicals.
If chemically defined but in retail packaging with additives
Prepared chemical compositions or mixtures not purely anhydrous ammonia shift to Chapter 38 miscellaneous chemicals.

Import Tips & Compliance
• Obtain EPA registration for anhydrous ammonia imports due to its hazardous nature; ensure cylinders meet DOT specifications for pressure vessels
• Verify purity certificates to avoid misclassification as aqueous solution
• Common pitfall: inadequate hazardous material declarations leading to customs delays
