Triple-rinsed IBC totes
A triple-rinsed IBC tote has been flushed three times with water or a suitable solvent after emptying. It is the standard RCRA cleaning for containers that held acute hazardous waste. It is still the original bottle, and not food grade unless the history is documented.

What it looks like
It looks like a rinsed tote, slightly cleaner. The valve and the underside of the cap are the places to check, since residue collects there. A bottle that is truly triple-rinsed has no film and almost no smell.
There is no outside sign of the method. The only proof is a record: who rinsed it, with what, and when.
How a tote gets this grade
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, or an equivalent cleaning, or after removal of its inner liner. That is a legal definition of empty, not a purity claim.
For a tote that did not hold waste, triple rinsing is simply a thorough wash done three times. The grade tells you the method, not the safety.
The jobs it suits and the ones it never does
Suits
- Irrigation, rain and wash-down.
- Storage of non-food liquids where traces do not matter.
- Sell-on or recycling, where a tote that is empty under RCRA is easier to move.
Never
- Drinking water or food product without a documented food-grade history.
- Pharma or any regulated product.
- Hazmat repeat fills without a retest.
What to check before you say yes
- The rinse record: what was used and by whom.
- The last contents.
- A smell test at the cap.
- Residue at the valve.
In South Florida
Triple-rinsed totes come mostly from plants around Medley, Hialeah and Pompano Beach that have an environmental manager who writes the rinse down. A grower gets a better tote and a paper trail.
If a seller in Doral says their totes are triple-rinsed, ask for the record. A grade is only as good as the paper behind it.
Mistakes we see
- Treating triple-rinsed as food grade.
- Taking the word "clean" without a record.
- Disposing of the rinse water down a drain.
- Skipping the check at the valve.
Reading the paperwork and the plate
Ask for the rinse record in writing, with the date, the person, the liquid used and where the rinse water went. A record of three rinses is worth more than a verbal promise, and it protects you if the tote is later questioned. The record is also what separates a triple-rinsed tote from one that was only hosed out.
Keep in mind that the regulation covers a legal definition of empty for hazardous waste, not drinking-water cleanliness. A tote can meet that definition and still carry a smell or a tint in the plastic. Treat the grade as the start of your own check, not the end of it.

Questions people ask
Where does the rinse water go?
That depends on what it carried. Ask the environmental manager or the product's safety data sheet; never pour it into a storm drain, a canal or the soil.
Do you accept a rinse record in any format?
A dated line from the person who did the work is enough to start: product, liquid used, number of rinses and where the water went.
What does RCRA empty mean for a tote?
For a container over 119 gallons that held hazardous waste, it is empty when pumped out with no more than one inch, or 0.3 percent by weight of capacity, remaining. See RCRA empty explained.
Is triple-rinsed the same as clean?
No. It is a method. The last contents decide what is left in the plastic.
Who does the rinsing?
Usually the seller or a washer. We ask for the record.
Is the rinse water waste?
It can be. Ask your environmental manager before you pour it anywhere.
Can I use a triple-rinsed tote for plants?
Yes, when the last contents were non-hazardous. Flush once more at home.
