Sodium bicarbonate intended for use as a food ingredient or pharmaceutical excipient falls under FDA jurisdiction. Importers must ensure the foreign manufacturer is registered with FDA and that the product meets applicable purity standards (such as USP or food-grade specifications). FDA may sample and examine shipments at the port of entry; prior notice of food shipments is required under the Bioterrorism Act. Consult a licensed customs broker or regulatory counsel to confirm current admissibility requirements.

Industrial-grade sodium bicarbonate used in flue-gas treatment or pool pH adjustment faces minimal regulatory review, while food-, feed-, and pharmaceutical-grade material triggers agency oversight. Pricing, purity specifications, and packaging requirements also differ substantially by grade. Clearly declaring the grade and end use in entry documentation helps avoid holds and facilitates correct duty assessment.
