3923.21.00.80 - With no single side exceeding 75 mm in length

This HTS subheading, 3923.21.00.80, encompasses sacks and bags, including cones, manufactured from polymers of ethylene, specifically when no single side of these articles exceeds 75 millimeters in length. This criterion is crucial for classification, indicating that these are generally small to medium-sized flexible packaging items. Examples include small drawstring bags, produce bags with dimensions within the specified limit, or small pouches used for packaging individual items.

It is important to distinguish this category from its sibling, 3923.21.00.85, which specifically covers polyethylene retail carrier bags (PRCBs) that are larger, defined by having lengths or widths between 6 inches (152.4 mm) and 40 inches (1,016 mm). Therefore, 3923.21.00.80 is for smaller ethylene polymer sacks and bags that do not meet the size specifications of PRCBs or the "Other" category under 3923.21.00.95. The defining characteristic for this classification is the constraint on the maximum length of any single side.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is determined solely by the material (polymers of ethylene) and the specific dimensional limitation (no single side exceeding 75 mm). Customs officials will rely on these physical attributes to correctly assign goods to this code, ensuring accurate import and export processing.
