Spherical glass microspheres with a refractive index greater than 1.9, ranging from 100 to 300 microns, used for retroreflective highway markings. These microspheres are under 1 mm in diameter and are not coated with a reflecting layer as defined in chapter note 2, so they fall under tariff item 7018.20.00.

Import Tips
• Ensure the microspheres are not coated with a metallic or chemical layer that could be considered a 'reflecting layer' under chapter note 2, as that note applies to glass sheets, but be prepared to explain the distinction
• Provide the refractive index data to support the product's intended use
• Confirm the diameter is within the 1 mm limit for all particles
