Last updated: April 2026 dataBeyond toothpaste and floss, a broad range of oral-care products — denture fixative pastes and powders, mouthwashes, breath fresheners, and whitening rinses — fall under this residual heading at tariff line 3306900000. Ireland leads US imports under this heading, reflecting the significant pharmaceutical and consumer-health manufacturing base there; Canada and Germany are also major sources. FDA's regulatory treatment varies by product: mouthwashes are typically cosmetics, while products making antimicrobial or therapeutic claims may be reviewed as OTC drugs.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Both denture fixative pastes/powders and cosmetic whitening rinses fall within 3306900000 as oral hygiene preparations not elsewhere specified. The classification is product-function based, not ingredient based. However, if a whitening product contains hydrogen peroxide at levels that trigger drug status, FDA admissibility requirements change even though the HTS classification remains the same.
For cosmetic mouthwashes, FDA generally requires a standard entry with accurate labeling; no premarket approval is needed. If the product carries an antimicrobial or therapeutic claim (e.g., gingivitis prevention), it may be subject to OTC drug monograph compliance, requiring evidence of conformance with the applicable monograph and proper labeling. Consulting a licensed customs broker or regulatory counsel before the first shipment is advisable.
