Heading 6217 is explicitly 'not elsewhere specified or included' (NESOI), so it applies only after ruling out every named heading. Work through the specific headings for the article type first — brassieres, ties, gloves, scarves, and so on — and use 6217 only when no named heading fits. When in doubt, a CBP binding ruling is the most reliable path.

Potentially, but classification of cut fabric components is fact-specific. Panels that are clearly identifiable as parts of a specific garment and not suitable for other uses may qualify under 621790. However, fabric cut to shape but not yet assembled into a recognizable part may instead be classified as fabric under the relevant textile chapter. The degree of further processing required and the specificity of the cut are the determining factors.
