Harmonized System Code Classification

28
Classification: Chemical products
Description: This chapter includes:
- Inorganic chemicals, e.g., sodium chloride, sulfuric acid, aluminum oxide
- Organic chemicals, e.g., ethylene, propylene, benzene, methanol
- Derivatives of organic chemicals
- Fine chemicals
- Isotopes of chemical elements
- Fertilizers
- Other chemical products

If your product falls into any of the above categories, its HS code is likely to start with "28".

2853
Classification: Phosphides, whether or not chemically defined, excluding iron phosphides; other inorganic compounds (including distilled water or water of similar purity); liquid air (whether or not rare gases have been removed); compressed air; mercury alloys, excluding mercury alloys of precious metals
Description: This HS code covers various phosphides, as well as other inorganic compounds, such as distilled water, liquid air, and compressed air. It also includes mercury alloys that are not made of precious metals.

Classification: Phosphides, whether or not chemically defined, excluding iron phosphides; other inorganic compounds (including distilled water or water of similar purity); liquid air (whether or not rare gases have been removed); compressed air; mercury alloys, excluding mercury alloys of precious metals
Description: Phosphides, whether or not chemically defined, excluding iron phosphides; other inorganic compounds (including distilled water or water of similar purity); liquid air (whether or not rare gases have been removed); compressed air; mercury alloys, excluding mercury alloys of precious metals, specifically: Other -> Phosphides, whether or not chemically defined, excluding iron phosphides -> Phosphorus copper (phosphorus copper), with a phosphorus content by weight greater than 15%.

2853901000
