HS code for Calcium chloride: 2827.20

Chlorides, of calcium.

Classification of calcium chloride under HS 2827.20

Calcium chloride is classified under Harmonized System (HS) code 2827.20. This classification is precise and unambiguous, as the HS description explicitly states "Chlorides; of calcium." This places calcium chloride within Chapter 28, which covers inorganic chemicals, and specifically within the subheading for chlorides. The direct mention of "of calcium" ensures that this particular salt is consistently classified under this code, distinguishing it from other chloride compounds. This includes calcium chloride in various forms, such as anhydrous, dihydrate, or hexahydrate, and in different physical states like flakes, pellets, or liquid solutions.

Covers
  • Anhydrous calcium chloride pellets or flakes.
  • Calcium chloride dihydrate.
  • Calcium chloride solutions for industrial use.
  • Food-grade calcium chloride.
  • Calcium chloride used as a desiccant or de-icing agent.
Also under 2827.20
  • Dow Chemical Calcium Chloride
  • OxyChem Calcium Chloride
  • Tetra Technologies Calcium Chloride
  • Cargill Road Salt

Codes often confused with 2827.20

Common mistake. Calcium chloride might be confused with other chlorides, such as sodium chloride (HS 2501.00 for common salt, or 2827.10 for chemically pure) or magnesium chloride (HS 2827.31). The critical distinction for HS 2827.20 is the specific cation "calcium." Misclassification could occur if the product is a mixture containing calcium chloride but is primarily identified by another component, or if it is a different chloride altogether. For example, brine solutions containing multiple salts would need careful analysis to determine the predominant component for classification.

Top exporters and importers of HS 282720 (the code used for calcium chloride), 2025

In 2025, the largest exporter of HS 282720 (the code used for calcium chloride) in UN Comtrade data was China, with 27% of world exports; the largest importer in UN Comtrade data was Mexico, with 22% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
