What decides the code
Zipper storage bags of polyethylene are classified as plastic sacks and bags under heading 3923, specifically 3923.21.00.30 for reclosable bags with an integral extruded closure.
- Material is polyethylene, a polymer of ethylene, which places the bag in 3923.21 rather than other plastic bag subheadings.
- The bag is reclosable with an integral extruded closure, the zipper profile, which fits the 3923.21.00.30 line.
- The bag is a sack or bag for conveyance or packing of goods, which brings it under heading 3923.
Common mistakes
- Classifying under 3923.29, the subheading for sacks and bags of other plastics, is wrong because the bag is polyethylene, a polymer of ethylene.
- Classifying under 3923.30 for bottles, flasks and similar articles is wrong because the product is a bag, not a container of that type.
- Classifying under 3923.50 for stoppers, lids and caps is wrong because the zipper is part of the bag, not a separate closure article.
