Last updated: August 2026 dataCalcium hypochlorite — the active ingredient in granular pool shock and industrial bleaching agents — enters the US under a single 10-digit line (2828100000) covering both commercial-grade and other forms. India is the leading import source, followed by Mexico and the United Kingdom. The compound's oxidizing nature subjects it to DOT hazardous materials regulations during transport, and importers must ensure proper UN packaging, labeling, and emergency response documentation accompany each shipment.

Calcium hypochlorite is classified as a Division 5.1 oxidizer under DOT and IMDG regulations. Shipments must use UN-approved packaging, carry proper hazard labels and markings, and be accompanied by a safety data sheet and, for ocean freight, a dangerous goods declaration. Importers should also verify EPA Toxic Substances Control Act (TSCA) compliance if the material is not already on the TSCA inventory.
The heading covers both commercial calcium hypochlorite (a mixture typically containing 65–70% available chlorine along with calcium chloride and calcium carbonate) and purer forms. The single 10-digit line 2828100000 captures all variants, so the grade distinction does not create a classification split at the 10-digit level — but it is commercially significant for pricing, specification compliance, and end-use suitability.
