Products classified under HTS 2814.10.00.00
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.
Fertilizer-Grade Anhydrous Ammonia
High-purity anhydrous ammonia specifically formulated for direct application in agriculture as a nitrogen source. Classified under HTS 2814.10.00.00 because it is anhydrous ammonia meeting chemical purity standards of Chapter 28. It is transported in refrigerated tankers for field injection.
Refrigerant-Grade Anhydrous Ammonia (R717)
Ultra-pure anhydrous ammonia used as refrigerant gas R717 in industrial cooling systems like cold storage warehouses. It qualifies for HTS 2814.10.00.00 as chemically defined anhydrous ammonia without water content. Known for its efficiency in large-scale refrigeration.
Laboratory-Grade Anhydrous Ammonia
High-purity anhydrous ammonia supplied in small cylinders for chemical synthesis and research applications. Falls under HTS 2814.10.00.00 as it is purely anhydrous and chemically defined per Chapter 28 notes. Used in producing pharmaceuticals and analytical reagents.
Anhydrous Ammonia for Nitric Acid Production
Technical-grade anhydrous ammonia used as feedstock in the Ostwald process for manufacturing nitric acid. Classified in HTS 2814.10.00.00 due to its anhydrous state and role as a simple inorganic compound. Supplied in bulk for chemical plants.
Pharmaceutical-Grade Anhydrous Ammonia
USP-grade anhydrous ammonia for use in pharmaceutical manufacturing and as a reagent in drug synthesis. Meets HTS 2814.10.00.00 as pure, anhydrous ammonia per chemical definition notes. Packaged in medical-grade cylinders.
Anhydrous Ammonia for Explosives Manufacturing
High-spec anhydrous ammonia used in the production of ammonium nitrate for mining explosives. Classified under HTS 2814.10.00.00 as anhydrous per Chapter 28 purity standards. Requires strict security protocols for import.
