3923.21.00.11 - With no single side exceeding 75 mm in length

This HTS category, 3923.21.00.11, specifically covers plastic sacks and bags manufactured from polymers of ethylene that are designed to be reclosable and feature an integral extruded closure. The defining characteristic for this subcategory is that none of the sides of the bag or sack exceed 75 millimeters in length. This size limitation is a critical factor in differentiating these specific articles from other types of polyethylene bags and sacks.

This classification is distinct from its siblings, 3923.21.00.20 and 3923.21.00.30, primarily based on the type of closure mechanism. While 3923.21.00.20 covers reclosable bags with integral extruded closures that utilize separate sliders to open or close the seal, and 3923.21.00.30 encompasses other types of sacks and bags of polymers of ethylene not specifically defined by their closure type or size, this particular subcategory is reserved for those where the extruded closure itself is integral to the bag's structure and the overall dimensions are small.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 3923.21.00.11 relies directly on the material (polymers of ethylene), the form (sacks and bags), the type of closure (reclosable with integral extruded closure), and the specific dimensional constraint (no single side exceeding 75 mm). This precise definition ensures that only very small, reclosable polyethylene bags with integrated extruded closures are classified under this heading.
