Both decorative glass beads and glass microspheres not exceeding 1 mm in diameter fall within this SITC heading, but they occupy different HTS subheadings at the 10-digit level and serve entirely different industries. Industrial microspheres used in road markings or composite materials must be distinguished from decorative beads on the commercial invoice and entry documentation to ensure correct subheading assignment and accurate statistical reporting.

Lamp-worked glass articles are produced by melting glass rods or tubes with a torch (lamp) and shaping them by hand — a technique that results in intricate figurines, ornaments, and novelty items. This manufacturing method is a classification criterion: lamp-worked glass ornaments belong here, while cast or pressed glass decorative articles of similar appearance may fall under a different heading. Supplier documentation describing the production method is important for supporting the classification.
