Antidumping duty orders on saccharin from certain countries have been in place for extended periods and are subject to periodic sunset reviews by the USITC and Commerce Department. Importers should check the current status of any applicable orders through the Commerce Department's Enforcement and Compliance portal and factor potential antidumping cash deposits into landed-cost calculations.
Saccharin intended for food or beverage use must comply with FDA food additive regulations and applicable labeling requirements. Import entries may be flagged for FDA review; supporting documentation such as a certificate of analysis, manufacturer's declaration of intended use, and compliance with applicable food-grade specifications should accompany the shipment. Consult a licensed customs broker or FDA regulatory specialist to confirm current admissibility requirements.
