Import Tips & Compliance
• Classify the crystals under 2841.61.00 and ensure the invoice clearly states the chemical name and CAS number (7722-64-7) for CBSA verification
• Be aware of the oxidizer classification for transport and storage, and keep records of the shipment for potential audits
• If the crystals are for laboratory use, confirm they are not subject to any special controls

ACS Reagent Potassium Permanganate
ACS reagent grade potassium permanganate (KMnO4) is a chemically defined compound of an inorganic base, meeting the purity standards for analytical chemistry and titration applications. It falls under tariff item 2841.61.00 as a permanganate salt of an oxometallic acid, specifically the potassium salt, and is not excluded by Chapter 28 notes.
Industrial Potassium Permanganate Flakes
Industrial potassium permanganate flakes are the same chemically defined compound (KMnO4) presented in a flaked physical form for easier dissolution in large-scale water purification systems. The physical form does not alter classification, and it remains within tariff item 2841.61.00 as the potassium salt of permanganic acid.
Technical Grade Potassium Permanganate
Technical grade potassium permanganate powder with a minimum 99% purity is a chemically defined compound used in industrial oxidation and wastewater treatment. Despite the lower grade, it is still the pure potassium salt of permanganic acid and falls under tariff item 2841.61.00, as Chapter 28 covers separate chemically defined compounds regardless of purity.
USP Grade Potassium Permanganate
USP grade potassium permanganate is a high-purity form of KMnO4 intended for pharmaceutical and medical uses such as wound disinfection. As a chemically defined compound of mercury-free inorganic base, it is classified under tariff item 2841.61.00, and Chapter 28 notes do not exclude it based on grade or intended use.
