TOUGH. STACKABLE. READY FOR THE LINE.

UN-Rated Pails

Certified Constructions for Regulated Transport

UN-rated pails are manufactured and tested to a hazardous-material packaging standard for regulated liquids and solids in transport. The rating lives in the whole package, not the pail alone, so every rated pail ships with its certified lid and closure instructions.

Overview

UN 1H2 plastic and 1A2 steel constructions covering Packing Group II and III, verified by drop, leak, and stack testing. The marking still has to be checked against your product's classification, packing group, and specific gravity.

Steel drum faqs

What does UN rated mean on a pail?

A UN-rated pail has been manufactured and tested to a hazardous-material packaging standard, verified by drop, leak, and stack testing. The marking states the packing group and maximum specific gravity it covers.

What is the difference between 1H2 and 1A2?

1H2 designates a plastic pail with a removable head; 1A2 designates a steel pail with a removable head. Plastic suits corrosive chemistries, steel suits solvents and flammables that need a groundable body.

Does a UN-rated pail need its certified lid?

Yes. The rating applies to the complete package, so substituting a different lid voids it. Every rated pail ships with its certified lid and closure instructions.

What packing groups do UN pails cover?

Packing Group II and III ratings are available, which covers most regulated liquids and solids shipped in pails. Your product's classification determines which rating applies.

How high can 5-gallon pails be stacked?

Filled pails generally stack three to four high, though the limit depends on contents, wall thickness, lid style, and storage conditions. Always follow the manufacturer's stacking and weight instructions.
