RE: The classification of Sepabeads SP207 (CAS-87924-01-4)
adsorption resins from Japan.
Dear Ms. O'Brien:
In your letter dated October 5, 1998 you requested a tariff
Sepabeads SP207 is described as a macroporous chemically
modified brominated styrenic polymeric bead type resin made of
benzene, diethenyl-, polymer with ethenylbenzene, brominated.
The polystyrene matrix forms a rigid aromatic non-polar surface
and the bromination of the aromatic ring provides increased
hydrophobicity, and consequently, increased selectivity for non-polar molecules. The adsorption mechanism is via low energy van
der Waal's interactions. The bromination allows for settling in
fermentation broths and for usage in upflow fluidized bed contact
The applicable subheading for the Sepabeads SP207 styrene
based adsorbent resin will be 3903.90.5000, Harmonized Tariff
Schedule of the United States (HTSUS), which provides for other
polymers of styrene in primary forms. The rate of duty is 0.2
cents per kilogram plus 7 percent ad valorem.
