Magnesium fluoride and sapphire optical windows and blanks will be used in devices which operate in the ultraviolet range of the electromagnetic spectrum. The other products are used in devices which operate in the infrared range of the electromagnetic spectrum. The applicable subheading for the optical windows and blanks will be 9001.90.9000, Harmonized Tariff Schedule of the United States (HTS), which provides for other optical elements, of any material, unmounted. The duty rate will be 7.3 percent ad valorem.

A copy of this ruling letter should be attached to the entry documents filed at the time this merchandise is imported. If the documents have been filed without a copy, this ruling should be brought to the attention of the Customs officer handling the transaction. Sincerely, Jean F.
