HS Code 3923.21 – Ethylene polymers; sacks and bags (including cones), for the conveyance or packing of goods

HS code 3923.21 is the 6-digit subheading for ethylene polymers, sacks and bags (including cones), for the conveyance or packing of goods. It is used for HDPE shopping bags, LDPE garbage bags, polyethylene produce bags, stretch film rolls and industrial PE sacks.

What HS 3923.21 covers

This specific code targets sacks and bags, including cones, made from ethylene polymers, primarily polyethylene (PE). These products are ubiquitous in packaging due to their versatility, cost-effectiveness, and barrier properties, ranging from simple shopping bags to heavy-duty industrial sacks. International trade in these goods is massive, driven by consumer goods, retail, agriculture, and industrial sectors worldwide. Importers are typically retailers, food processors, agricultural businesses, and industrial manufacturers, while exporters are large-scale plastic film and bag producers. Key considerations include film thickness, strength, printability, biodegradability (for certain types), and compliance with food safety regulations, all of which impact their market value and application. The environmental impact of these products is also a growing concern in global trade.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
