Last updated: July 2026 dataSodium bicarbonate — universally recognized as baking soda — enters US commerce under a single tariff line (2836300000) but serves a wide spectrum of end uses: food leavening, pharmaceutical antacid formulations, animal feed buffering, and industrial applications such as flue-gas desulfurization. Germany and France are the leading import sources, supplying high-purity pharmaceutical and food grades that complement domestic US production. Food-grade and pharmaceutical-grade imports are subject to FDA admissibility review; importers should maintain certificates of analysis and ensure labeling meets FDA requirements. Consult a licensed customs broker or FDA-registered agent regarding grade-specific compliance obligations.

Food-grade sodium bicarbonate must meet FDA purity standards and is subject to admissibility review as a food additive or GRAS substance. Technical-grade material used in industrial applications such as flue-gas treatment or fire suppression is not subject to FDA food-additive requirements, though it must still be correctly classified. The HTS line is the same for both grades, so the intended use and grade designation on the commercial invoice and certificate of analysis are critical for determining the applicable regulatory pathway at entry.
European producers, particularly in Germany and France, have established reputations for pharmaceutical-grade and ultra-high-purity sodium bicarbonate that meets stringent pharmacopoeial standards (USP, EP). US importers in the pharmaceutical and specialty food sectors often source from these origins to meet specification requirements that domestic commodity-grade production may not consistently satisfy.
