About HS Code 900190
This HS code encompasses unmounted optical elements such as lenses, prisms, mirrors, and other components, made from any material, provided they are not optically unworked glass. These are fundamental building blocks for a vast array of optical instruments and systems. Major importers are manufacturers of high-tech equipment, including cameras, telescopes, microscopes, medical diagnostic devices, laser systems, and scientific research instruments, who integrate these precision components into their final products. Exporters are typically specialized optical fabrication companies with advanced capabilities in grinding, polishing, and coating. Key considerations in international trade for these goods include material purity, surface quality, precise geometric specifications, and specialized coatings (e.g., anti-reflective, dielectric), which significantly impact performance and cost. The global supply chain for these elements often involves highly specialized manufacturers providing components to larger integrators worldwide.
Products Under This Code
Unmounted spherical lenses, Unmounted aspheric lenses, Optical prisms, First surface mirrors, Beam splitters, Cylindrical lenses, Diffractive optical elements, Optical flats
Real World Examples
Edmund Optics plano-convex lenses, Thorlabs right-angle prisms, Schott optical glass blanks, Newport dielectric mirrors, Melles Griot cylindrical lenses
Common Misclassification
This code is often confused with mounted optical elements (9002.90) or raw optical glass in bulk (7006.00). The key distinction is that 9001.90 covers finished, unmounted optical components, not raw material or assembled parts.
Products Classified Under 9001.90
Industry
This code belongs to the Electronics & Electrical Equipment industry.
Trade Overview
Germany, Japan, China, and the USA are prominent players in both importing and exporting these high-precision optical components.
