Nothing here is a pail or a drum, and nothing carries a UN specification marking.

The measured ceiling

The largest container on this shelf is 4,731 mL, about a gallon and a quarter, and it is the largest container in the entire catalog. The archetype window for this group runs to 20,000 mL.

So four fifths of the window is unserved

A 5-gallon pail, a 15-gallon keg and a drum are all inside the archetype’s range and outside our stock. For an industrial chemical sold in quantity that is the format the market uses.

And no specification packaging at all

Measured across all 2,150 products, nothing carries a UN specification marking. For a DOT hazardous material in a quantity requiring specification packaging, this catalog cannot supply the container.

Which is the same finding that excluded a whole group

The hazmat group was set aside for exactly this reason and it is recorded as an open task. The distinction is that an industrial chemical below the specification thresholds, or under a limited quantity provision, can be served here.

The limited quantity route is where this shelf works

Inner packagings not over 0.5, 1.0 or 5.0 liters by packing group, in a strong outer packaging, with no package over 30 kg gross. Most of this shelf sits comfortably inside those inner limits.

So the honest market for it

Reagent and laboratory quantities, sample and trial sizes, and retail or small-trade packs of cleaning and maintenance chemistry. All real, and all below the point where specification packaging takes over.

Ask a packaging manufacturer for the rest

Specification containers are built and marked to a standard with continuing qualification behind them, and they come from manufacturers who do that. It is a different supply chain and we would rather name it than imply otherwise.

Knowing where a shelf ends is part of its usefulness

A catalog that stops at a gallon and a quarter is honest about serving reagent and small-trade quantities. Implying it reaches drum volumes would waste somebody's week.

Written from federal regulation and from measured catalog data, not from a plant floor. Hazard classification is a technical exercise with appendices behind it, and nothing here classifies a chemical or writes a label. The point of these pages is to show which regime applies and what it asks for.
