20l jerry can

For metal cans, ensure they are made of 0.8mm to 1.0mm cold-rolled steel with an anti-corrosive internal lining (usually fuel-resistant ammonia-alkyd enamel). For plastic versions, High-Density Polyethylene (HDPE) is mandatory due to its high strength-to-density ratio and chemical resistance. Always verify that the material is UV-stabilized to prevent brittleness during outdoor storage.

The most vital certification is the UN Packaging Certification (UN Mark), which indicates the container has passed drop, leak-proof, and internal pressure tests. For the European market, TÜV/GS certification is highly preferred. If used for fuel, the product must comply with AS/NZS 2906:2001 (Australia/Oceania) or EPA/CARB standards (USA) regarding permeation and spill control.

Prioritize a triple-handle design which allows for easy carrying by one or two people and facilitates 'bucket brigade' passing. Ensure the locking pin (Bayonet closure) is secure and includes a leak-proof gasket made of fuel-resistant rubber (Viton or NBR). A built-in breather pipe or an air-vent channel in the spout is essential for a glug-free, smooth pour.

Request a pressure test report; a high-quality 20L can should withstand internal pressure of at least 100-250 kPa. Examine the seam welding—automated plasma welding is superior to manual welding as it reduces the risk of pinhole leaks. For painted cans, check for powder coating rather than liquid paint to ensure superior scratch and rust resistance.

The biggest risk is non-compliance with dangerous goods regulations, which can lead to customs seizure or heavy fines. Another risk is shipping damage; because Jerry Cans are hollow, they are prone to denting. Ensure the supplier uses five-layer corrugated export cartons and consider palletized shipping with edge protectors to maintain structural integrity.

Focus on the Total Cost of Ownership (TCO). Ask for a breakdown of the steel/plastic grade used to ensure they aren't cutting costs with thinner walls. Negotiate for custom branding/embossing (MOQ usually 500-1000 units) and request a spare parts kit (extra gaskets and locking pins) to be included at no extra cost for bulk orders.

Jerry Cans are 'high-volume, low-weight' cargo. To optimize freight costs, use nested loading if the design allows, or ensure the supplier maximizes container utilization (CBM). If the cans are pre-filled (rare for sourcing), they fall under Class 3 Flammable Liquids; however, empty cans are generally treated as standard cargo but must be declared as 'Empty UN-Rated Packaging' to avoid confusion at customs.

Always hire a third-party inspection agency (like SGS or Intertek) to perform a Random Sampling Inspection before the final balance is paid, specifically focusing on the leakage test (submerging the can in water).
