Harmonized System Code Classification

28
Classification Reason:
The HS code "28" belongs to the chemical products category.

Specifically, this category includes:

• Inorganic chemicals: Such as oxides, hydroxides, halides, sulfates, carbonates, silicates, etc.
• Organic chemicals: Such as hydrocarbons, alcohols, ketones, acids, esters, amines, aldehydes, polymers, etc.
• Fine chemicals: Including medicines, pesticides, dyes, pigments, perfumes, reagents, etc.
• Other chemical products: Including fertilizers, explosives, adhesives, surfactants, etc.

Why are these products classified under "28"?
Because these products are manufactured or refined through chemical methods, and they have specific chemical compositions and properties. They are widely used in industrial production, agriculture, medicine, and scientific research.

In short, "28" represents all kinds of chemical substances obtained through chemical reactions or chemical processing.

If you want to know more detailed classification information, you can provide a more specific HS code (e.g., 2801, 2815, etc.), and I will do my best to explain it for you.
