7002.39.00.90 - Other

This HTS category, 7002.39.00.90, encompasses "Other" tubes of glass, unworked, that are not microspheres and do not fall under the specific length limitation of the sibling category. This classification applies to glass tubing in various shapes and dimensions, intended for further processing or use, where such tubing is not further specified by length or other characteristics defined in preceding subheadings. Examples include glass tubes with irregular cross-sections, or those with significant wall thickness variations not covered elsewhere.

This category distinguishes itself from sibling category 7002.39.00.10 by its lack of a length restriction. While 7002.39.00.10 specifically addresses glass tubes not exceeding 200 millimeters in length, 7002.39.00.90 covers all other unworked glass tubes that do not meet this specific length criterion, or any other specific exclusions. The key differentiating factor is the absence of the 200 mm length constraint for goods classified under this heading.

As a leaf node, this category has no further subcategories. Therefore, classification into 7002.39.00.90 is final once the goods meet the general criteria for unworked glass tubes within heading 7002 and do not fit into any more specific preceding subheadings. The classification relies on the absence of specific length, form, or other defining characteristics that would warrant placement in a more granular HTS code.
