Triple-rinsed IBC totes: flushed three times

01What this grade is

Under 40 CFR 261.7, a container that held an acute hazardous waste is empty only after triple rinsing with a solvent capable of removing the product, an equivalent cleaning, or removal of its inner liner. A triple-rinsed tote is one that has had that treatment. That is a regulatory state, not a quality grade.

The three rinses do not change the bottle. The tote may still have absorbed some of the last contents into its plastic, and it is not food grade unless its history is documented. The grade tells the next owner the tote is clean to the rule.

02What to look at

03What it fits and what it rules out

04Which way it trades here

Sellers post it: plants whose last contents trigger the rule. Buyers are fewer, and often recyclers or users of the same product.

The desk treats an unknown or acute hazardous last content as an inquiry first, and moves a triple-rinsed tote only after the paperwork says so.

05What to put on the ticket

• What the tote last held and the SDS
• The rinse medium and who did it
• The size and count

06Where triple rinsing comes from

Triple rinsing is a standard in the federal waste rules. Under 40 CFR 261.7, a container that held an acute hazardous waste is empty only after it has been triple rinsed with a solvent capable of removing the product, cleaned by an equivalent method, or had its inner liner removed. For containers over 119 gallons that held ordinary hazardous waste, the test is residue of no more than one inch or 0.3 percent of capacity by weight.

The desk uses the grade as a promise about process, not about outcome. A tote labelled triple-rinsed says the plant followed three flushes with fresh water, draining fully between each, and the ticket should name who did it and when. It does not say the bottle is food grade, and it does not say a regulated chemical cannot remain in the plastic.

A triple-rinsed tote is a better candidate for a farm, a nursery or a water use than a simply rinsed one, and it can be a candidate for a chemical user whose own product is compatible.
