BTI (Binding Tariff Information) is an official EU customs decision confirming the classification of goods. Valid for 3 years, binding across all EU member states.

Description of large plastic tanks

CN code 3925 10 covers reservoirs, tanks, vats and similar containers of plastics with capacity exceeding 300 litres. These are large containers for storing and transporting liquids, bulk materials and chemicals. Common materials include rotomoulded HDPE, PP, GRP (glass-reinforced polyester) and lined PE. Rotomoulded HDPE tanks reach capacities up to 50,000 litres for water, chemicals, fuels and agricultural materials. IBC (Intermediate Bulk Containers) of 1,000 litres in metal cages are logistics standards.

Regulations and safety standards

Import is subject to REACH. Drinking water tanks must meet Regulation (EU) 2020/2184. Dangerous goods transport tanks (IBC, cisterns) require UN certification per ADR/RID/IMDG. EN 12573 covers welded thermoplastic tanks. Pressure vessels fall under PED (2014/68/EU). Underground tanks are subject to environmental leak prevention regulations.

Trade and classification

Tanks over 300 litres fall under 3925 10; containers up to 300 litres under 3923 10. IBC with plastic inner container in metal cage are classified by inner container material (plastic = 3925 10). Documentation should specify capacity, material, intended use and UN/ADR certificates.

Properties of Plastic tanks over 300 litres and trade applications

Products classified under CN code 3925 10 as construction products fall under the Construction Products Regulation CPR (EU) 305/2011. Import requires CE marking, Declaration of Performance (DoP) and compliance with relevant harmonised EN standards. Customs clearance requires certification documents, installation instructions and technical data sheets. Products must meet fire reaction class and mechanical resistance requirements.

Frequently asked questions

What certificates are required for IBC tanks?
IBC for dangerous goods transport must hold UN certification confirming ADR/RID/IMDG compliance. Certification includes strength tests: hydrostatic test, drop test, stacking test and leakage test. IBC must carry UN marking identifying type, material, production date and permitted packing groups. Food-grade IBC additionally require food contact compliance documentation.
What materials are used in large tanks?
Tanks over 300 litres are made from: rotomoulded HDPE - dominant for water, chemicals and fuels; welded PP - for aggressive chemicals; GRP - for underground tanks and cisterns; cross-linked PE (XLPE) - for higher thermal resistance; and glass fibre composites - for pressure vessels.
How to distinguish code 3925 10 from 3923 10?
The distinguishing criterion is capacity: CN code 3925 10 covers containers exceeding 300 litres, while 3923 10 covers smaller boxes and containers. The 300-litre threshold is the tariff boundary. IBC containers of 1,000 litres are classified under 3925 10. Customs documentation should clearly state the container capacity in litres.
Do products CN 3925 10 require CE marking for EU import?
Yes, products CN 3925 10 as construction products require CE marking under CPR (EU) 305/2011. A Declaration of Performance (DoP) and compliance with the relevant harmonised EN standard are mandatory.
