Last updated: April 2026 dataFunctioning as a residual catch-all for synthetic and blended waxes not captured by more specific headings, this category includes chemically modified natural waxes, polyolefin waxes, Fischer-Tropsch waxes, and proprietary blended formulations used across packaging, coatings, rubber processing, and candle manufacturing. The breadth of the heading means that classification disputes are relatively common — particularly for wax blends where the base material is ambiguous — and importers often benefit from supplier-provided composition certificates. Fischer-Tropsch waxes, derived from coal or gas-to-liquids processes, are a commercially significant subset with growing use in hot-melt adhesives and PVC processing.

A detailed composition certificate from the manufacturer — specifying the base wax type, chemical modification method, melting point, and any additive content — is the most effective supporting document. For borderline cases between this NES heading and more specific wax headings, a binding ruling request to CBP provides certainty before large shipments are committed.
Yes, Fischer-Tropsch waxes — produced by catalytic synthesis from syngas derived from coal, natural gas, or biomass — are typically classified in this NES heading. They are prized for their very high melting points, narrow carbon-number distribution, and low oil content, which make them superior to paraffin in demanding hot-melt adhesive, PVC lubricant, and printing ink applications.
