3919.10.10 - Having a light-reflecting surface produced in whole or in part by glass grains (ballotini)

This HTS category, 3919.10.10, specifically covers self-adhesive plates, sheets, film, foil, tape, strip, and other flat shapes of plastics, presented in rolls with a width not exceeding 20 cm, and possessing a light-reflecting surface that is produced in whole or in part by glass grains (ballotini). These characteristics are crucial for distinguishing these items from other self-adhesive plastic products. The inclusion of glass grains for light reflection is the defining feature for classification under this specific heading.

Distinguishing this category from its sibling, 3919.10.20, "Other," is paramount. While both fall under self-adhesive plastics in rolls not exceeding 20 cm in width, 3919.10.10 is exclusively for products utilizing glass grains to achieve their reflective properties. The sibling category encompasses all other self-adhesive plastic tapes and similar forms in this width that do not incorporate glass grains for light reflection, such as plain adhesive tapes or those with other types of reflective coatings.

The subcategories under 3919.10.10 further refine the classification based on the specific application of these reflective plastic products. "Pavement marking tape" (3919.10.10.10) represents a primary use, specifically designed for road and highway delineation due to its high visibility. The "Other" subcategory (3919.10.10.50) captures any remaining products that meet the primary criteria of having a glass-grain-produced light-reflecting surface and being in rolls not exceeding 20 cm, but do not fall under the dedicated pavement marking designation.
