HS code for Calcium hypochlorite: 2828.10
Hypochlorites, commercial calcium hypochlorite and other calcium hypochlorites.
Classification of calcium hypochlorite under HS 2828.10
Calcium hypochlorite is classified under Harmonized System (HS) code 2828.10. This classification is highly specific, as the HS description explicitly covers "Hypochlorites; commercial calcium hypochlorite and other calcium hypochlorites." This places calcium hypochlorite within Chapter 28, which deals with inorganic chemicals, and specifically within the subheading for hypochlorites. The direct mention of "commercial calcium hypochlorite" and "other calcium hypochlorites" ensures that both technical grades and more refined forms of this compound are consistently classified under this single code, recognizing its widespread use as a disinfectant and bleaching agent.

Codes often confused with 2828.10
Common mistake. Calcium hypochlorite might be confused with other hypochlorites, such as sodium hypochlorite (HS 2828.90, under "other hypochlorites"). The critical distinction for HS 2828.10 is the specific cation "calcium." Misclassification could occur if the product is a mixture containing calcium hypochlorite but is primarily identified by another component, or if it is a different hypochlorite altogether. For example, liquid bleach, which is typically sodium hypochlorite solution, would fall under HS 2828.90. Careful attention to the specific chemical composition and the "of calcium" qualifier is essential.

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).
