3923.21.00.20 - Other, with sliders that open or close the seal

This HTS category, 3923.21.00.20, specifically covers plastic sacks and bags of polymers of ethylene that are designed with integral extruded closures featuring sliders for opening and closing the seal. These are distinct from other types of bags and sacks by their specific closure mechanism.

It is important to differentiate this subcategory from its sibling, 3923.21.00.11, which covers bags with no single side exceeding 75 mm in length. The defining characteristic here is the presence of a slider-operated closure, regardless of the bag's dimensions beyond what is generally covered by the parent category. The sibling 3923.21.00.30 encompasses all other bags and sacks of polymers of ethylene with integral extruded closures that do not meet the criteria for this specific subcategory or the 75 mm dimension limitation.

As this is a leaf node, there are no further subcategories. Classification within this code is contingent upon the presence of a slider mechanism to open or close the seal on sacks and bags manufactured from polymers of ethylene. The intent is to isolate and classify items with this particular type of reclosable feature.
