HS Code for Sodium molybdate

Sodium molybdate is classified under HS code 2841.70. This classification falls under Chapter 28, which encompasses inorganic chemicals, and Heading 2841, which is dedicated to salts of oxometallic or peroxometallic acids. Specifically, subheading 2841.70 is reserved for molybdates. Sodium molybdate (Na2MoO4) is the sodium salt of molybdic acid. It is commonly found in the dihydrate form (Na2MoO4·2H2O). The classification is based on the chemical identity of the substance as a salt of an oxometallic acid (molybdic acid). Sodium molybdate is used in various industrial applications, including as a corrosion inhibitor in cooling towers, a reagent in analytical chemistry, and a micronutrient in fertilizers to treat molybdenum deficiency in plants. As a separate chemically defined compound, it is correctly placed in Chapter 28. The classification remains the same whether the product is in anhydrous or hydrated form, as per the General Rules of Interpretation and the Chapter 28 notes.

Common Misclassification

A common misclassification occurs when sodium molybdate is intended for use as a fertilizer. While it is a micronutrient, pure sodium molybdate remains under 2841.70. It only moves to Chapter 31 (Fertilizers) if it is mixed with other fertilizing substances or put up in specific retail packings as a fertilizer. Another error is classifying it under 2841.90, which is the "other" category for salts of oxometallic acids; however, since molybdates are specifically mentioned in 2841.70, that code must be used. It should also not be confused with molybdenum oxides, which are classified under 2825.70.
