Harmonized System
Structurally defined by a methyl group and a 2-hydroxyethyl group on the sulfonamide nitrogen, this perfluorooctane sulfonamide variant is enumerated at HS6 heading 293540, separate from the N-methyl and N-ethyl forms. Germany is the leading documented US supplier. As with all PFOS-related compounds, EPA's TSCA framework — including applicable Significant New Use Rules — governs import and use, and importers should confirm current regulatory status before shipment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The sole structural difference is the methyl versus ethyl group on the nitrogen. Historically, both served as fluorosurfactant intermediates, but their distinct structures can affect reactivity and end-product performance. For customs purposes, a certificate of analysis confirming the methyl substituent is the key document separating classification under 293540 from 293530.
Based on available schedule data, no 10-digit children lines are enumerated for this heading. The heading is treated as a single undivided provision, meaning all qualifying imports are reported under the HS6 code without further US-specific subdivision.
