HS Code for Potassium perchlorate

Potassium perchlorate is classified under HS code 2829.90. This classification falls under heading 2829, which encompasses chlorates and perchlorates; bromates and perbromates; iodates and periodates. Within this heading, the subheadings 2829.11 and 2829.19 are reserved for chlorates of sodium and other chlorates, respectively. Consequently, perchlorates, including the potassium salt, are categorized under the "Other" subheading, 2829.90. The classification is based on the chemical's nature as an inorganic salt of perchloric acid (HClO4). Potassium perchlorate is a powerful oxidizing agent used extensively in the pyrotechnics industry, ammunition, and rocket propellants. As a separate chemically defined compound, it is correctly placed in Chapter 28. The high oxygen content and specific chemical structure distinguish it from other halides or simpler oxides, necessitating its placement within the perchlorate group.

Products Included

• Potassium perchlorate in crystalline or powder form
• Pyrotechnic grade potassium perchlorate
• Technical grade potassium perchlorate for industrial oxidizers
• Potassium perchlorate used in laboratory reagents
• High-purity potassium perchlorate for specialized chemical synthesis

Common Misclassification

Potassium perchlorate is often misclassified under HS code 2829.19, which is for "other chlorates." While chlorates and perchlorates are related, they are chemically distinct (ClO3 vs ClO4), and the HS structure separates them at the subheading level. Another common misclassification is under HS code 3604.90, which covers pyrotechnic articles. While potassium perchlorate is a component of fireworks, the raw chemical itself must be classified in Chapter 28, not as a finished pyrotechnic product.

FAQ

What is the HS code for potassium perchlorate?

The HS code for potassium perchlorate is 2829.90, which includes perchlorates, bromates, and iodates.

Is potassium perchlorate considered a hazardous material for shipping?

Yes, for transport purposes, it is classified as a Class 5.1 oxidizing substance. However, this transport classification is separate from its HS code classification for customs duties.
