What HS 2828.10 covers
This HS code specifically covers calcium hypochlorite, a widely traded chemical renowned for its potent oxidizing and disinfecting properties. It is a cornerstone in global water treatment, sanitation, and various industrial applications, particularly for swimming pool maintenance and public health. Countries with large populations, extensive public health infrastructure, or significant industrial water usage are major importers, including developing nations and those with robust tourism sectors. Exporters are typically large-scale chemical producers with the capacity for bulk manufacturing, such as China, India, and the USA. Key aspects of trade include ensuring proper packaging to prevent moisture absorption and decomposition, strict adherence to safety regulations for hazardous materials, and efficient logistics for bulk shipments. The demand for calcium hypochlorite remains consistently high due to its essential role in maintaining public health and hygiene worldwide, making it a stable commodity in the chemical trade.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
