HS code 3925.90 is the 6-digit subheading for plastics, builders' ware, n.e.c. or included in heading no. 3925. It is used for plastic gutters, downpipes, fascias, soffits and skirting boards.
What HS 3925.90 covers
This 'not elsewhere specified' category within plastic builders' ware captures a wide array of plastic components essential for construction that do not fit into the more specific subcategories like doors, windows, or tanks. It includes items such as plastic gutters, downpipes, fascias, skirting boards, wall panels, and various fittings. Importers are typically building material suppliers, construction companies, and renovation contractors seeking durable and cost-effective solutions. Exporters are specialized plastic extrusion and molding companies with expertise in producing construction-grade materials. The trade is driven by the ongoing demand for lightweight, low-maintenance, and weather-resistant building materials, with a growing emphasis on ease of installation and aesthetic integration into modern architectural designs, contributing significantly to both new builds and renovation projects.

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).
