HS Code for Potassium peroxide

Potassium peroxide (K2O2) is classified under HS code 2815.30, which specifically covers the peroxides of sodium or potassium. This classification is governed by the General Rules for the Interpretation (GRI) of the Harmonized System, particularly Rule 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Within Chapter 28, which encompasses inorganic chemicals, heading 2815 is structured to include sodium hydroxide, potassium hydroxide, and the peroxides of these two alkali metals. Potassium peroxide is an inorganic compound that serves as a powerful oxidizing agent. It is primarily used in specialized environments such as submarines, spacecraft, and breathing apparatuses because of its unique ability to react with carbon dioxide to release oxygen while simultaneously removing the CO2 from the air. The classification under 2815.30 is strictly based on its chemical identity as a metallic peroxide. It is essential for customs purposes to distinguish this from simple oxides or hydroxides, as the peroxide linkage (O-O) defines its chemical behavior and its specific placement within the 2815 heading.

Common Misclassification

Potassium peroxide is frequently misclassified under HS code 2815.20, which is reserved for potassium hydroxide (caustic potash). While both are potassium compounds under the same heading, 2815.20 is for the hydroxide (KOH), whereas 2815.30 is specifically for the peroxide (K2O2). Another common error is attempting to classify it under 2804.40 for oxygen, given its use in oxygen generation, but the HS system prioritizes the chemical composition of the substance itself over its functional output.

FAQ

What is the HS code for potassium peroxide?

The HS code for potassium peroxide is 2815.30, which covers peroxides of sodium or potassium.

Is potassium peroxide classified as a hazardous material for shipping?

Yes, due to its strong oxidizing properties, potassium peroxide is typically classified as a Class 5.1 hazardous material (oxidizer) for transport, though its HS classification remains 2815.30 regardless of its transport safety category.
