RE: The classification of Diaion HPK25 (CAS-68441-33-8); HPA25
(CAS-60177-39-1); and HPA75 (CAS-68441-27-0) ion exchange
resins from Japan.
Dear Ms. O'Brien:
In your letter dated October 5, 1998 you requested a tariff
classification ruling.
Diaion HPK25 is a macroporous ion-exchange resin based on
sulfonated styrene and divinylbenzene copolymer sodium salt.
The primary styrene monomer acts as a rigid framework and the
functional cationic (sulfonated) monomer derivative provides the
ion exchange properties. It is used for the removal and/or
recovery of cationic heavy metal components from waste waters in
the metal plating industry.
Diaion HPA25 is a macroporous ion-exchange resin based on
ethenyl-N,N,N-trimethyl benzenemethanaminium chloride and
divinylbenzene polymer. The primary styrene monomer acts as a
rigid framework and the functional anionic (chloromethylated)
monomer derivative provides the ion exchange properties. It is
used for adsorption of high molecular weight compounds, such as
various bioactive substances and enzymes in the bio/pharma-ceutical industry.
Diaion HPA75 is a macroporous ion-exchange resin based on
styrene-divinylbenzene copolymer, chloromethylated, dimethyl-ethanolamine quaternary ammonium chloride. The primary styrene
monomer acts as a rigid framework and the functional anionic
(chloromethylated) monomer derivative provides the ion exchange
properties. It is used for adsorption of high molecular weight
compounds, such as various bioactive substances and enzymes in
the bio/pharmaceutical industry.
The applicable subheading for all three products will be
3914.00.6000, Harmonized Tariff Schedule of the United States
(HTSUS), which provides for ion-exchangers based on polymers of
headings 3901 to 3913, in primary forms: other. The rate of duty
is 3.9 percent ad valorem.
