Product classification
HS code for Plastic construction products: 3925.90
Plastics, builders' ware, n.e.c. or included in heading no. 3925.
Classification of plastic construction products under HS 3925.90
Plastic construction products are classified under HS code 3925.90, which falls within Chapter 39 of the Harmonized System. This chapter generally covers plastics and articles thereof. Heading 3925 is specifically dedicated to "builders' ware of plastics, not elsewhere specified or included." This classification is determined by the intended permanent installation of the product within a building or structure. To qualify for this heading, the items must be used in the construction of floors, walls, ceilings, or roofs, or be fixtures that become a permanent part of the building. Subheading 3925.90 acts as a residual category for builders' ware that does not fit into the more specific subheadings for reservoirs (3925.10), doors and windows (3925.20), or shutters and blinds (3925.30). The classification relies on the physical properties of the plastic and its application in the construction industry. If an item is made of plastic but is not intended for permanent incorporation into a structure, it cannot be classified here and must be moved to general plastic article headings.

Codes often confused with 3925.90
Common mistake. A frequent misclassification occurs with HS code 3926.90, which is the general category for "other articles of plastics." Importers often use this code for construction items that lack a specific name, but if the item is builders' ware, 3925.90 takes precedence. Another common error involves HS code 3917, which covers tubes, pipes, and hoses. While some construction products are pipe-like, if they are specifically designed as builders' ware (like specialized drainage channels), they may be argued into 3925.90. Furthermore, items that are not permanently fixed, such as portable plastic partitions, should be classified under 3926 rather than 3925.

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).
