HS Code 2827.20 – Chlorides; of calcium
HS code 2827.20 is the 6-digit subheading for chlorides, of calcium. It is used for anhydrous calcium chloride, calcium chloride flakes, calcium chloride pellets, food grade calcium chloride and industrial grade calcium chloride.
What HS 2827.20 covers
Calcium chloride is a widely traded inorganic salt, known for its hygroscopic properties and diverse applications. It's heavily imported by countries in colder climates for de-icing roads and by regions with significant construction activity for concrete acceleration. Food processing industries, particularly in developed nations, import it as a firming agent and preservative. The oil and gas sector also demands large quantities for drilling fluids. Key aspects of its trade include its various forms (flakes, pellets, powder, liquid solution) which impact shipping and handling, and its different grades (food, industrial). Its effectiveness as a desiccant and its role in industrial processes make it a staple in global chemical trade, with demand fluctuating based on seasonal weather patterns, infrastructure projects, and food industry trends.

Codes often confused with 2827.20
Common mistake. Sometimes confused with other road salts like sodium chloride (250100) or magnesium chloride (282731) due to similar de-icing applications, but 282720 is specific to calcium chloride.
Top exporters and importers of HS code 282720, 2025
In 2025, the largest exporter of HS code 282720 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).
