7002.10 - Balls:

This HTS category, 7002.10, specifically covers glass in the form of balls, excluding microspheres which are classified under heading 7018. These glass balls are considered "unworked," meaning they have not undergone significant shaping, finishing, or processing beyond their initial formation. The primary characteristic for classification within this heading is the spherical shape of the glass article.

It is important to distinguish this category from its siblings. HTS code 7002.20 covers glass in the form of rods, which are elongated, cylindrical shapes, while the unclassified "Tubes" would refer to hollow, cylindrical glass articles. Therefore, 7002.10 is exclusively for solid, spherical glass items.

The subcategories within 7002.10 further refine the classification based on the physical dimension of the glass balls. The distinction between "Not over 6 mm in diameter" (7002.10.10.00) and "Other" (7002.10.20.00) allows for more granular tariff application, likely correlating to different uses or manufacturing processes for smaller versus larger glass balls. This level of detail ensures accurate duty assessment.
