U.S. exports of Unworked Glass Balls (Excluding Microspheres) (HS 700210) totaled $1.6M in August 2026.

Last updated: August 2026 dataUnworked glass balls larger than 1 mm in diameter — distinct from the hollow glass microspheres of heading 7018 — are used as grinding media, retroreflective road-marking beads, and precision bearing elements. The US schedule divides them by diameter: balls not over 6 mm (7002101000) and balls over 6 mm (7002102000), a split that tracks the primary end-use markets for fine grinding media versus larger industrial and decorative applications. China dominates supply, with Germany and Canada contributing precision-grade product for optical and industrial uses.

Heading 7002.10 covers solid or hollow glass balls exceeding 1 mm in diameter that have not been further worked. Glass microspheres of heading 7018 are typically hollow, very small (generally under 1 mm), and used in specialty applications such as reflective coatings, syntactic foam, and medical devices. The diameter threshold and the degree of further processing are the primary classification criteria; product technical data sheets specifying diameter and wall construction are the key supporting documents.
The 6 mm diameter breakpoint (separating 7002101000 from 7002102000) can affect both the applicable duty rate and any trade-remedy exposure, as the two lines are separately enumerated in the US tariff schedule. Importers should measure and document ball diameter accurately — typically via manufacturer's specification sheets or quality-control certificates — since misclassification between the two lines is a straightforward CBP audit target for this commodity.
