Classification of plastic storage tanks under HS 3925.10
Plastic storage tanks with a capacity exceeding 300 liters are classified under HS code 3925.10. This code is part of Chapter 39 (Plastics) and specifically falls under heading 3925, which covers builders' ware of plastics, not elsewhere specified or included. Subheading 3925.10 is designated for reservoirs, tanks, vats, and similar containers. The critical factor for this classification is the capacity; the container must hold more than 300 liters. These items are typically used in building or construction contexts for the storage of water, chemicals, or other fluids. The classification is guided by Note 11 to Chapter 39, which defines builders' ware to include these large-scale containers. If the tank is integrated into a specific machine or vehicle, the classification would change, but as a standalone storage unit for building or industrial use, 3925.10 is the standard. This heading is restricted to items that are not for the conveyance or packing of goods, which are instead covered by heading 3923. The 300-liter threshold is a strict legal requirement for classification under 3925.10, following the General Rules of Interpretation to ensure consistency across international trade.

Codes often confused with 3925.10
Common mistake. The most common misclassification is HS code 3923.90, which covers containers for the conveyance or packing of goods. However, 3923 is generally intended for smaller containers or those used in transport. If the tank is a permanent fixture or part of a building's infrastructure, 3925.10 takes precedence. Another error is using HS code 3926.90 for general plastic articles. If the capacity is 300 liters or less, the item cannot be classified under 3925.10 and would likely fall under 3923 or 3924 depending on its design and purpose.

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).
