N320257 · 2021-07-20 — The tariff classification of a BGO (Bismuth Germanium Oxide) shield from Sweden.
Louis. The BGO (Bismuth Germanium Oxide) shield will be incorporated into the payload of a stratospheric balloon flight experiment. The shield is made of three main components: (1) a 35.1 kg BGO crystal and a 6.9 kg BGO crystal, (2) an Al housing to hold the crystal and to keep it in a light tight environment, and (3) 8 Hamamatsu Photomultiplier Tubes (PMTs) with biasing electronics. The objective of the BGO shield is to detect X-rays that come from the X-ray mirror, which is part of the payload, through the opening in the BGO shield. The crystal scintillates when struck by energetic…
N196627 · 2012-01-05 — The tariff classification of x-ray detectors from the United Kingdom
No samples were provided. Per the copy you submitted of the PerkinElmer Product Note, your CMOS Digital X-ray Flat Panel Detectors are, typically, about 20 by 10 centimeters. They are “designed as components to be integrated into a complete X-ray system by imaging system manufacturers” for “Industrial, Medical, Dental, Veterinary and Life Sciences” uses. They are sold with a “range of scintillator and interface options.” You propose classification in HTSUS 9022.14.00 if “for medical and veterinary uses” and in HTSUS 9022.19.00 if “for other uses, i.e., industrial application.” You do not…
R04500 · 2006-07-30 — The tariff classification of Digital X-ray Detectors from Germany
No sample was submitted. You state, “PerkinElmer’s amorphous silicon flat panel detectors use a solid state sensor as a two-dimensional photodiode array. The detectors are well suited to perform digital image acquisition and contain all drive and read-out processing electronics including an X-Ray interlock. X-Rays are converted into light using different scintillators. The information is digitized in 16 bit to achieve highest dynamic range and contrast. PerkinElmer currently offers 3 main versions of Amorphous Silicon Radiation Image Detectors (or XRDs): The XRD 512-400 series with its 8” 512…
I81299 · 2002-05-28 — The tariff classification of an "On-Trak" measuring-while-drilling system and various components. The country of origin is not stated.
As indicated by the submitted descriptive literature, the “On-Trak” measuring-while-drilling (MWD) system is designed to provide directional drilling guidance capabilities and formation evaluation data in the surface and subsurface drilling field. It enables a drilling operator to navigate a drill bit along a desired path based upon collected data and other parameters. The complete system is comprised of subassemblies (steel drill collar sections), a surface transponder, and a surface work cabin with workstations that control the subassemblies and process data. The applicable subheading for…
h86817 · 2002-01-29 — The tariff classification of an X-ray detector panel from Canada
In its imported state, no sample provided, “the panel would consist of TFT (Thin Film Transistor) panels laminated to a sheet of glass for added strength. These panels would have amorphous selenium coated onto the panel.” From the information provided, the imported detector array is 14 by 17 inches in size and is the “heart” of the digital detector. This import will lack the electronics of the controller/computer which will be needed to produce images from its electrical output. The final images will be similar to, but more precise than, the images produced on a traditional, direct view,…
