SITCSection 8
U.S. imports of parts and accessories of liquid crystal devices, non-diode lasers, and other optical instruments, n.e.s. (SITC 87199) totaled $35.9M in April 2026, traded with 47 countries.
Importers of Parts and Accessories of Liquid Crystal Devices, Non-Diode Lasers, and Other Optical Instruments, N.E.S. paid $3.4M in duties in April 2026 — an effective duty rate of 14% on $23.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts and Accessories of Liquid Crystal Devices, Non-Diode Lasers, and Other Optical Instruments, N.E.S. imports of $35.9M in April 2026 ran 22% above the year-to-date monthly average of $29.3M.
Last updated: April 2026 dataSpare and replacement parts for the residual optical instrument categories — liquid crystal devices, non-diode lasers, and miscellaneous optical appliances — are grouped here when they cannot be classified under a more specific parts heading. The breadth of the parent categories means this heading attracts a wide variety of components, from laser resonator mirrors and cooling assemblies to LCD driver boards, making precise technical documentation essential to support classification. Importers should be alert to Section 301 duty exposure for parts sourced from China, particularly for laser and LCD subsystems where Chinese supply chains are prevalent.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A resonator mirror designed exclusively for use in a non-diode laser system would typically classify as a part of a laser under this heading, provided it is not more specifically described elsewhere (e.g., as a worked optical element under a separate optics heading). The key evidence is the mirror's optical coating specification and the manufacturer's documentation tying it to a specific laser platform.
Yes — the classification of LCD-related parts depends on the nature of the component. Purely optical elements (polarizers, diffusers, light guides) tend to classify here, while integrated circuit drivers or backlight inverter boards may fall under electronic component headings. A component-by-component analysis is necessary for complex LCD module kits.
