Last updated: July 2026 dataA residual catch-all for HFC-containing blends drawn from the specific hydrofluorocarbon compounds enumerated in subheadings 2903.41 through 2903.48, this subheading captures formulations not covered by the more compositionally defined 382761–382765 provisions. China and the Netherlands are the leading US suppliers, with Mexico, Taiwan, and the United Kingdom also contributing to import flows. Because this is an NESOI category, correct classification requires ruling out all more specific HFC blend subheadings before applying it — a step that demands detailed composition data. Chinese-origin imports are subject to Section 301 tariffs.

The importer should obtain a full mass-percentage composition certificate for the blend and systematically check it against the threshold criteria for each of the specific HFC blend subheadings (382761 through 382765). Only after confirming the blend does not meet any of those thresholds — and that it contains HFCs from the 2903.41–2903.48 range — should 382768 be applied. A binding ruling request to CBP can provide certainty for recurring shipments.
The Netherlands functions primarily as a European logistics and chemical distribution hub; much of the HFC blend volume attributed to Dutch origin reflects blending, repackaging, or re-export of components sourced elsewhere in Europe or Asia. Importers should verify the country of origin carefully, as the origin of the blend (where substantial transformation occurred) may differ from the country of shipment.
