Last updated: April 2026 dataCalcium chloride is a high-volume industrial salt used for road de-icing, dust suppression, oil-well completion fluids, and concrete acceleration—applications that make it one of the more widely traded inorganic chlorides by tonnage. Classified under a single 10-digit line (2827200000), it is imported in flake, pellet, and liquid solution forms, each with different bulk-handling and freight considerations. Mexico and China are the leading US suppliers, with Canada a significant third source; Mexico's proximity and USMCA eligibility give it a logistics advantage for large-volume, lower-margin applications like road treatment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
All physical forms of calcium chloride—anhydrous, dihydrate flake, pellet, or aqueous solution—classify under 2827200000. However, the form affects the concentration declared on the commercial invoice (typically expressed as % CaCl₂ by weight for solutions), which customs may scrutinize to confirm the product is not a dilute mixture that could be reclassified. Liquid solution shipments also require proper UN hazardous-materials documentation for transport.
Calcium chloride originating in Mexico and meeting USMCA rules of origin qualifies for preferential tariff treatment. Given Mexico's position as the leading US supplier, many importers already structure their sourcing to take advantage of this, particularly for high-volume road-treatment contracts where duty savings on large tonnages are meaningful.
