Last updated: August 2026 dataCommercially known as soda ash, disodium carbonate is a foundational industrial alkali consumed in glass manufacturing, chemical synthesis, water treatment, and pulp and paper production. Mexico is the leading US import source under this heading — a reflection of both geographic proximity and large-scale trona-based soda ash production in North America — with France and Sweden also supplying volumes. The US is itself a major global producer of natural soda ash from Wyoming trona deposits, so imports tend to fill specific grade or logistics gaps rather than representing primary supply. All entries fall under the single tariff line 2836200000.

US domestic production from Wyoming trona is cost-competitive for dense soda ash grades used in glass and chemicals, but importers may source foreign material for specific light-grade or refined specifications, to serve coastal markets where ocean freight is economical, or to meet contractual supply-diversification requirements. European suppliers like France and Sweden often supply higher-purity or specialty grades not always available domestically.
Importers should verify whether antidumping or countervailing duty orders are in effect for soda ash from specific origins at the time of entry, as trade remedy coverage can change. The US International Trade Commission and Commerce Department maintain current order lists. A licensed customs broker can confirm the applicable duty treatment for a given country of origin before contracting.
