Last updated: April 2026 dataGuaifenesin (2909490500) — the active expectorant ingredient in widely used OTC cough and cold products — is among the most commercially significant individually enumerated compounds in this heading, and its imports are subject to FDA oversight as a drug substance. The heading also covers glycerol ethers (2909492000), di-pentaerythritol (2909493000) used in alkyd resins and lubricant additives, and a broad residual category of non-aromatic ether-alcohols (2909496000). India leads US supply across this heading, with Taiwan and Japan also significant sources. Importers of guaifenesin should ensure the foreign manufacturer holds an FDA Drug Master File and that the shipment complies with current Good Manufacturing Practice requirements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Guaifenesin imported as an active pharmaceutical ingredient (API) must come from an FDA-registered foreign facility, and the manufacturer typically maintains a Drug Master File (DMF) referenced in the importer's drug application. FDA may conduct foreign facility inspections and can place a facility on import alert if cGMP deficiencies are found, resulting in automatic detention of shipments.
Di-pentaerythritol of 94% or more purity by weight is specifically enumerated under 2909493000 within this heading. Lower-purity material or technical-grade mixtures may classify differently depending on composition. Importers should obtain a certificate of analysis confirming purity to support the claimed 10-digit classification and avoid potential reclassification at entry.
