8414.30.80.90 - For ammonia

This HTS classification covers compressors specifically designed and used within refrigerating equipment where the refrigerant is ammonia. These compressors are integral components of systems that facilitate cooling or air conditioning processes when ammonia is the chosen refrigerant. The classification hinges on the compressor's intended application in a refrigeration cycle and the specific type of refrigerant it is engineered to handle.

Distinguishing this category from its sibling, "For all refrigerants except ammonia," is critical. While both cover compressors used in refrigerating equipment, this specific classification is exclusively for those designed to work with ammonia. This distinction is based on the unique chemical properties and operational requirements of ammonia as a refrigerant, necessitating specialized compressor designs and materials to ensure safe and efficient operation. Compressors intended for other refrigerants, such as HFCs or HCFCs, would fall under the aforementioned sibling category.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, the classification concludes at this level. Goods classified here are typically industrial-scale compressors found in commercial refrigeration units, food processing facilities, and large-scale air conditioning systems where ammonia is employed for its thermodynamic properties. The defining characteristic remains the specific compatibility with ammonia refrigerant.
