Last updated: August 2026 dataPhenol-formaldehyde resins — commercially known as phenolics or Bakelite-type resins — are critical binders and adhesives in plywood, brake linings, abrasive wheels, and electrical laminates, valued for their heat resistance and dimensional stability. All US imports are classified under a single 10-digit line (3909400000). Canada is the leading supplier, consistent with its large forest-products industry that consumes phenolic resins as wood-panel binders; Singapore and Germany are also significant sources.

Resoles are base-catalyzed, one-stage phenolic resins that cure without added hardener, while novolacs are acid-catalyzed, two-stage resins requiring a curing agent such as hexamethylenetetramine. Both types are classified under 3909400000 — the HTS does not subdivide phenolic resins by cure chemistry. The distinction matters commercially for end-use specification and pricing but not for tariff classification.
Canada is the leading supplier of phenolic resins to the US. Goods originating in Canada and meeting USMCA rules of origin are eligible for preferential tariff treatment under that agreement. Importers should ensure the product meets the applicable tariff-shift or regional-value-content requirements and obtain a valid USMCA certification of origin.
