HS Code 3925.20 – Plastics; builders' ware, doors, windows and their frames and thresholds for doors
HS code 3925.20 is the 6-digit subheading for plastics, builders' ware, doors, windows and their frames and thresholds for doors. It is used for UPVC windows, plastic door frames, vinyl patio doors, plastic window sashes and UPVC thresholds.
What HS 3925.20 covers
This category encompasses plastic components integral to building construction, specifically doors, windows, and their associated frames and thresholds. These products are widely adopted in residential, commercial, and industrial buildings due to their durability, excellent insulation properties, low maintenance requirements, and cost-effectiveness compared to traditional materials like wood or metal. Importers are typically construction companies, building material suppliers, and renovation contractors. Exporters are specialized manufacturers of UPVC (unplasticized polyvinyl chloride) or other plastic profiles and finished units. The trade is heavily influenced by construction booms, stringent energy efficiency regulations, and evolving architectural trends, with a strong focus on thermal performance, security features, and aesthetic design to meet modern building standards.

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).
