HS Code for Sodium chlorate

Sodium chlorate is classified under HS code 2829.11. This classification is governed by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically focusing on the chemical composition of the substance. Chapter 28 of the Harmonized Tariff Schedule is dedicated to inorganic chemicals, precious metal compounds, and rare-earth metals. Within this chapter, heading 2829 covers chlorates and perchlorates, as well as bromates, perbromates, iodates, and periodates. The subheading 2829.11 is specifically allocated to sodium chlorate. This classification applies to the chemical in its pure form or as a technical grade product. Sodium chlorate is a strong oxidizing agent produced through the electrolysis of sodium chloride solutions. It is primarily used in the pulp and paper industry for the on-site generation of chlorine dioxide, a key bleaching agent. Because it is a clearly defined inorganic salt, it remains within Chapter 28 regardless of its industrial application, provided it has not been mixed with other ingredients to form a prepared chemical product or herbicide.

Products Included

• Technical grade sodium chlorate crystals
• Sodium chlorate in aqueous solution (pure)
• Granular sodium chlorate for industrial use
• Reagent grade sodium chlorate for laboratory analysis
• Sodium chlorate used as a precursor for chlorine dioxide production

Common Misclassification

Sodium chlorate is frequently misclassified under HS code 3808.93, which covers herbicides and plant-growth regulators. While sodium chlorate is used as a non-selective herbicide, it only falls under heading 3808 if it is prepared in forms or packings for retail sale or as a preparation consisting of a mixture of active ingredients. If the product is pure sodium chlorate, it must remain in 2829.11. Another common error is confusing it with sodium hypochlorite (HS code 2828.90), which is also a bleaching agent but belongs to the hypochlorites heading. Additionally, it may be confused with sodium perchlorate, which is classified under 2829.90.

FAQ

What is the HS code for Sodium chlorate?

The international HS code for sodium chlorate is 2829.11, which specifically identifies the sodium salt within the category of chlorates.

Is sodium chlorate considered a hazardous material for shipping?

Yes, sodium chlorate is classified as a Class 5.1 oxidizing substance under the IMDG and IATA regulations. It requires specific hazardous material packaging, labeling, and documentation (UN number 1495) when being transported internationally, regardless of its HS code classification.
