HS Code for Sodium nitrite

Sodium nitrite is classified under HS code 2834.10. This classification is based on its chemical identity as a nitrite, which is a salt of nitrous acid (HNO2). Under the Harmonized System, Chapter 28 is dedicated to inorganic chemicals, and heading 28.34 specifically covers nitrites and nitrates. Subheading 2834.10 is reserved exclusively for nitrites of all metals. Sodium nitrite (NaNO2) is a distinct, chemically defined compound used extensively in industrial applications, such as the production of diazo dyes, as a corrosion inhibitor in metallurgy, and as a food preservative (E250). Because it is a separate chemically defined compound and does not meet the specific criteria for fertilizers or other specialized chapters, it is classified according to its chemical structure within the inorganic chemistry chapter. The classification remains consistent regardless of whether the product is in powder, flake, or granular form, provided it is not mixed with other substances in a way that changes its essential character.

Products Included

• Industrial grade sodium nitrite
• Food grade sodium nitrite (preservative E250)
• Technical grade sodium nitrite for dye manufacturing
• Sodium nitrite solutions (aqueous)

Common Misclassification

The most common misclassification for sodium nitrite is HS code 2834.21 or 2834.29, which are for nitrates. While the names are similar, nitrates (NO3) and nitrites (NO2) are chemically distinct and have different HS subheadings. Additionally, it is sometimes confused with sodium nitrate fertilizer (3102.50). However, sodium nitrite has no significant fertilizing value and is never classified in Chapter 31. Importers must ensure the chemical formula is verified to avoid the 2834.10 vs 2834.2x error.

FAQ

What is the HS code for sodium nitrite?

The HS code for sodium nitrite is 2834.10, which falls under the category of nitrites of inorganic chemicals.

Can sodium nitrite be classified as a food additive?

While it is used as a food additive, for customs purposes it is classified by its chemical composition under 2834.10 rather than as a prepared food ingredient, unless it is part of a complex mixture.
