RE: The tariff classification of Cycloserine (CAS# 68-41-7),
imported in bulk form, from Japan
Dear Mr. Chivini:
In your letter dated September 18, 1998, you requested a
tariff classification ruling.
The subject product, Cycloserine, which has the chemical
name of D-4-Amino-3-isoxazolidinone, is a naturally occurring
antibiotic produced by a strain of Streptomyces orchidaceus. It
has also been synthesized. Currently, Cycloserine is used, in
conjunction with other tuberculostatic drugs, in the treatment of
pulmonary or extrapulmonary tuberculosis, when primary agents,
such as isoniazid, rifampin, ethambutol and streptomycin, have
failed.
The applicable subheading for Cycloserine, imported in bulk
form, will be 2941.90.1050, Harmonized Tariff Schedule of the
United States (HTS), which provides for: "[A]ntibiotics: Other:
Natural ...... Other." The rate of duty will be free.
This merchandise may be subject to the requirements of the
Federal Food, Drug, and Cosmetic Act, which is administered by
the U.S. Food and Drug Administration. You may contact them at
5600 Fishers Lane, Rockville, Maryland 20857, telephone number
301-443-6553.
This ruling is being issued under the provisions of Part 177
of the Customs Regulations (19 C.F.R. 177).
A copy of the ruling or the control number indicated above
should be provided with the entry documents filed at the time
this merchandise is imported. If you have any questions
