HS Code for Hydrazine

Hydrazine is classified under HS code 282510, which specifically covers hydrazine and hydroxylamine along with their inorganic salts. This classification is determined by the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. As an inorganic base, hydrazine falls within Chapter 28, which encompasses inorganic chemicals, precious metals, and rare-earth metals. The specific subheading 282510 is designated for hydrazine and its derivatives because they are chemically defined inorganic compounds. The classification remains consistent regardless of whether the hydrazine is in anhydrous form or as an aqueous solution (hydrazine hydrate), provided no other substances have been added that would change its essential character as a basic chemical building block.

Common Misclassification

Hydrazine is frequently misclassified under HS code 282590, which is a residual category for other inorganic bases and metal oxides. However, because 282510 provides a specific named entry for hydrazine, it must take precedence. Another common error involves organic derivatives of hydrazine, such as methylhydrazine, which should be classified under HS code 292800 (Organic derivatives of hydrazine or of hydroxylamine) rather than the inorganic heading. Importers must distinguish between the pure inorganic base and its organic substituted counterparts to avoid customs delays.

FAQ

What is the HS code for Hydrazine?

The primary HS code for hydrazine, including its hydrate and inorganic salts, is 282510.

Is hydrazine hydrate classified differently than anhydrous hydrazine?

No, both anhydrous hydrazine and hydrazine hydrate are classified under HS code 282510, as the hydrate is considered an aqueous solution of the inorganic base.
