Parts & Accessories for Liquid Crystal Devices, Lasers & Other Optical Instruments (NESOI)

Parts for rifle telescopic sights may be subject to Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) regulations in addition to standard CBP entry requirements. Depending on the article's specifications and origin, export controls under the Export Administration Regulations or the International Traffic in Arms Regulations may also apply to re-export. Importers should confirm regulatory status before entry.

LCD parts that are identifiable as parts of the LCD device as a whole — such as polarizing films, diffuser sheets, or optical waveguide components — generally fall under 9013908000. However, purely electronic subassemblies (e.g., driver ICs or power supply boards) may be more properly classified in Chapter 85. The key test is whether the part's principal function is optical or electronic; a binding ruling from CBP provides the most reliable answer.
