HS Code for Sodium hypochlorite

Sodium hypochlorite is classified under HS code 2828.90. This classification is determined by the chemical's identity as an inorganic salt of an oxoacid of a halogen. Heading 2828 specifically covers hypochlorites, commercial calcium hypochlorite, chlorites, and hypobromites. Within this heading, the Harmonized System distinguishes between calcium-based hypochlorites (2828.10) and all other hypochlorites (2828.90). Sodium hypochlorite, commonly known as liquid bleach, falls into the latter category. The classification process follows General Interpretative Rule (GIR) 1, which states that classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 28 Note 1(b) is particularly relevant, as it allows for the inclusion of aqueous solutions of these chemicals, provided that the solution is a necessary and customary mode of transport for the chemical and that the solvent does not render the product particularly suitable for specific use rather than for general use. Sodium hypochlorite is almost always traded as an aqueous solution because the anhydrous form is highly unstable and explosive. Therefore, the solution remains in Chapter 28. If the product were to be mixed with detergents, perfumes, or other additives for retail sale as a household cleaner, it would likely be reclassified under Heading 3402 as a cleaning preparation.

Products Included

• Sodium hypochlorite aqueous solutions (industrial grade)
• Liquid bleach (without added surfactants or fragrances)
• Chlorinated soda solutions
• Sodium hypochlorite pentahydrate
• Pool chlorinating liquid (pure sodium hypochlorite base)

Common Misclassification

Sodium hypochlorite is frequently misclassified under HS code 3402.20 or 3402.90. This occurs when the product is marketed as a finished cleaning preparation containing surfactants. Another common error is using HS code 3808.94, which is reserved for disinfectants put up in forms or packings for retail sale. If the sodium hypochlorite is in bulk and not formulated, 2828.90 is the correct code.

FAQ

What is the HS code for sodium hypochlorite?

The HS code for sodium hypochlorite is 2828.90. This code applies to the chemical in its pure form or as an aqueous solution, provided no other functional ingredients are added.

Is sodium hypochlorite classified as a hazardous material?

Yes, for transport purposes, sodium hypochlorite is typically classified as a Class 8 corrosive substance. However, for customs classification, it remains under 2828.90 regardless of its hazard class, provided it meets the chemical definitions of Chapter 28.
