RE: The tariff classification of scintillation crystals from
Belarus.
Dear Mr. Trower:
In your letter dated August 25, 1993 you requested a tariff
classification ruling.
The laboratory grown inorganic scintillation crystals to be
imported will include the following five types:
1. YAP - YAlO3
2. LSO - LuSi2O5
3. LAO - LuAlO3
4. GSO - Gd2SiO3
USCS RULING MODULE SEE
5. PWO - PbWO4
All of the above will be used in nuclear particle detectors. In
some instances, the crystals will be imported uncut while in other
cases they will be imported cut and polished, ready for
installation in a particle detector.
Items 1 - 4 are doped with 1% Ce. Item 5 is undoped.
The applicable subheading for the uncut crystals, items 1
through 4, will be 3823.90.3900, Harmonized Tariff Schedule of the
United States (HTS), which provides for other mixtures of two or
more inorganic compounds. The rate of duty will be free. The
applicable subheading for the uncut PWO crystal, item 5, will be
2841.80.0050, HTS, which provides for salts of oxometallic or
peroxometallic acids: tungstates (wolframates). The rate of duty
will be 10 percent.

The applicable subheading for five types when cut and
polished, ready for installation will be 9030.90.4000, HTS, which
provides for parts and accessories of instruments and apparatus for
measuring or detecting ionizing radiations. The rate of duty will
be 4.7 percent.
This ruling is being issued under the provisions of Section
177 of the Customs Regulations (19 C.F.R. 177).
A copy of this ruling letter should be attached to the entry

brought to the attention of the Customs officer handling the
transaction.
