HS Code 3925.10 – Plastics; builders' ware, reservoirs, tanks, vats and similar containers of a capacity exceeding 300 litres

HS code 3925.10 is the 6-digit subheading for plastics, builders' ware, reservoirs, tanks, vats and similar containers of a capacity exceeding 300 litres. It is used for water storage tanks, septic tanks, chemical storage vats, rainwater harvesting tanks and industrial process tanks.

What HS 3925.10 covers

This code covers large-capacity plastic containers, specifically reservoirs, tanks, and vats, with a capacity exceeding 300 liters, primarily used in construction, agriculture, and industrial settings. These items are crucial for storing liquids or bulk materials, facilitating water management, chemical storage, and waste collection on a significant scale. Importers are typically construction companies, agricultural enterprises, industrial facilities, and municipal water authorities. Exporters are specialized manufacturers of large-format plastic molding, often employing rotational molding or blow molding techniques. The trade is driven by infrastructure development, industrial expansion, and the need for durable, corrosion-resistant, and often portable storage solutions, with a strong emphasis on safety standards and material compatibility for various contents.

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).
