Classification of plastic bobbins under HS 3923.40
Plastic bobbins are classified under HS code 3923.40, which covers spools, cops, bobbins, and similar supports made of plastic. Heading 3923 is designated for articles for the conveyance or packing of goods, of plastics; stoppers, lids, caps, and other closures, of plastics. Bobbins are essential components used to hold or wind yarn, wire, or film during transport or within a manufacturing process. The classification is determined by GRI 1, as the product's primary function is to act as a support for the conveyance of materials. Subheading 3923.40 specifically identifies these types of supports, distinguishing them from other plastic packaging materials like boxes, cases, or bags. These items are typically used in the textile, wire, and film industries to facilitate the handling and protection of the wound material during shipping and storage. The classification applies to bobbins of various sizes and shapes, provided they are made of plastic and intended for the support of materials during conveyance.

Codes often confused with 3923.40
Common mistake. Plastic bobbins are sometimes misclassified under 8448, which covers parts and accessories for textile machinery. However, if the bobbin is primarily used for the conveyance or packing of the yarn (even if used within a machine), 3923.40 is preferred. They may also be confused with 3926.90, but 3923.40 is the more specific heading for supports and spools. If the bobbin is made of paper or cardboard, it would fall under 4822.

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).
