Plastics, carboys, bottles, flasks and similar articles, for the conveyance or packing of goods.
Classification of plastic flasks under HS 3923.30
Plastic flasks are classified under HS code 3923.30, which covers articles for the conveyance or packing of goods. This classification is determined by the intended use of the product rather than its specific polymer type. According to the Explanatory Notes to the Harmonized System, heading 3923 includes containers used for the transport or commercial packaging of all kinds of products. For a flask to fall under 3923.30, it must be designed for 'conveyance'—meaning it is used to move goods from a producer to a consumer or between industrial facilities. This includes carboys, bottles, and flasks. The classification remains consistent regardless of whether the flask is made of polyethylene, polypropylene, or polyethylene terephthalate (PET). It is critical to distinguish these from domestic or 'tableware' flasks. If a flask is designed for household use, such as a reusable water bottle or a kitchen container, it may be redirected to heading 3924. However, industrial flasks and those used for retail packaging of liquids or powders are firmly situated in 3923.30.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
