N091163 · 2010-01-25 — The tariff classification of crystal wafers from China.
The items are described as circular crystal wafers made of CTGS (Calcium Tantalum Gallium Silicate), CTAS (Calcium Tantalum Aluminum Silicate), and CNGS (Calcium Niobium Gallium Silicate). The dimensions are typically 8 to 10 mm in diameter by 0.26 mm in thickness. The crystals are chemical derivatives of lanthanum gallium silicate (LGS) and are grown using a Czochralski method, similar to silicon wafers. These crystals are drawn from a melt consisting of calcium oxide, and either niobium or tantalum oxide – silicon oxide and either aluminum or gallium oxide to create the desired composition…

The following is our decision regarding Protest 3196-95-100326, which concerns the classification of unmounted piezo-electric crystals under the Harmonized Tariff Schedule of the United States (HTSUS). FACTS: The subject merchandise consists of unmounted piezo-electric crystals which are round, thin wafers, about the size of a thumbtack head, with a thickness of .002 inches. According to the information provided, cultured piezo-electric quartz crystal material is grown in bars (ingots), usually about 6 to 8 inches long. Each bar is a single crystal of quartz and might weigh about 1 kg. The…
894364 · 1994-02-03 — The tariff classification of unmounted quartz crystal blanks from Japan.
You have submitted samples of the quartz crystal blanks which you intend to import. They are unmounted piezo-electric quartz in the shape of either tiny rectangles or circular discs. The samples submitted are circular. They measure .312" in diameter and are about .003" thick. You feel that the correct classification of the quartz crystal blanks should be 8541.90.0000, Harmonized Tariff Schedule of the United States (HTS). Explanatory Note 85.41, Harmonized Commodity Description and Cording System ("HCDCS") indicates what is to be included in Heading 8541. The Explanatory Notes although not…
876481 · 1992-07-31 — The tariff classification of unmounted crystal quartz blanksfrom Japan.
You have submitted four samples of unmounted crystal quartz blanks. You state in your letter that these blanks are cut into a specific size and thickness to be mounted into crystal units and crystal oscillators to control the frequency. You have told us in your letter that the crystal quartz blanks are imported unmounted. You feel that the correct classification of the quartz crystal blanks may be parts of crystal units or parts of crystal oscillators under subheading 8541.90.0000, Harmonized Tariff Schedule of the United States (HTS). Explanatory Note 85.41, Harmonized Commodity Description…
