N029616 · 2008-06-30 — Tariff classification of phenolic resin coated sand proppant from Canada.
Prime Plus 40/70 is described as phenolic resin coated sand proppant. Proppants are injected deep into the hydraulically created fractures of low permeability oil reservoirs to keep the fractures open and maintain oil flow. The proppant resin is fully cured in situ. Because the resin is thermosetting, the cured proppant particles retain their pre-cured spherical shapes forming a filter large enough to permit oil flow out of the well bore. In your letter you proposed classification under subheading 3824.90.9290, HTSUS, which provides for chemical products and preparations of the chemical or…
