6105.20.20.20 - Imported as parts of playsuits (237)

This HTS subheading, 6105.20.20.20, specifically classifies knitted or crocheted shirts for boys when they are imported as parts of playsuits. This means that while the item is a shirt component, its classification is tied to its intended end-use within a larger garment assembly that meets the definition of a playsuit. The material composition will be of man-made fibers, consistent with the parent category.

Distinguishing this from its sibling, 6105.20.20.30, which is also for "Boys': Other" shirts of man-made fibers, is the crucial detail of being "imported as parts of playsuits." The sibling category would encompass all other knitted or crocheted boys' shirts of man-made fibers that are not designated for integration into playsuits. Therefore, the defining characteristic for this specific subheading is its functional context as a component of a playsuit.

As this is a leaf node in the HTS structure, there are no further subdivisions. Classification within 6105.20.20.20 is determined by the product being a boy's knitted or crocheted shirt made of man-made fibers and its specific importation status as a component of a playsuit. Importers must ensure that documentation clearly indicates this intended use to support the classification.
