HS Code for Ammonium metavanadate

Ammonium metavanadate is an inorganic salt with the chemical formula NH4VO3. In the context of the Harmonized System (HS), it is classified under Chapter 28, which covers inorganic chemicals, precious metal compounds, and radioactive elements. Specifically, it is placed under heading 2841, which is dedicated to salts of oxometallic or peroxometallic acids. The classification process follows the General Rules for the Interpretation (GRI) of the Harmonized System. GRI 1 dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since ammonium metavanadate is a salt of vanadic acid, which is an oxometallic acid, it naturally falls into heading 2841. However, because there is no specific subheading for vanadates (unlike aluminates or tungstates), it is categorized under the residual subheading 2841.90, which covers \"other\" salts of oxometallic acids. This product typically appears as a white-to-yellowish crystalline powder and is highly valued in industrial applications. It serves as a primary catalyst in the synthesis of organic compounds and is a crucial intermediate in the production of vanadium pentoxide. Its classification is strictly based on its chemical identity as a separate chemically defined compound, as per Note 1 to Chapter 28, which requires the substance to be a single chemical element or a single chemically defined compound, whether or not containing impurities.

Common Misclassification

Ammonium metavanadate is frequently misclassified under HS code 2825.30, which covers vanadium oxides and hydroxides. While it is a precursor to these oxides, the salt form must remain in 2841.90. Another common error is using HS code 2842.90, which is for other salts of inorganic acids; however, because vanadates are specifically salts of oxometallic acids, heading 2841 takes precedence over 2842. Additionally, some importers mistakenly use 3102.90 if they believe the product is a nitrogenous fertilizer, but ammonium metavanadate lacks the agricultural properties required for Chapter 31.

FAQ

What is the HS code for Ammonium metavanadate?

The HS code for ammonium metavanadate is 2841.90, which refers to salts of oxometallic or peroxometallic acids not elsewhere specified.
