3923.21.00 - Of polymers of ethylene

This HTS classification covers sacks and bags, including cones, specifically manufactured from polymers of ethylene. These articles are designed for the conveyance or packing of goods, leveraging the inherent properties of ethylene-based plastics such as flexibility, durability, and barrier protection. Examples within this category include common plastic shopping bags, garment bags, and industrial packaging sacks made from polyethylene (LDPE, HDPE, LLDPE).

This category is distinguished from its sibling, 3923.29.00.00, by the specific material composition. While 3923.29.00.00 encompasses sacks and bags made from *other* plastics, this code exclusively applies to those derived from ethylene polymers. Therefore, a classification decision hinges on accurately identifying the primary polymer used in the manufacture of the sack or bag.

The subcategories within this code further refine the classification based on specific design features. The first subcategory addresses sacks and bags with an integral extruded closure, often referred to as reclosable features, which are typically found on zipper-style bags. The "Other" subcategory encompasses all remaining sacks and bags of ethylene polymers that do not possess this specific type of closure mechanism. This subdivision allows for detailed tracking of different types of plastic packaging based on their closure design.
