The IBC tote reference library.
Plain-language guides to buying, cleaning, grading and reusing IBC totes. Nothing here is gated. When you are ready, a free quote request goes to partner suppliers in our network.
The short answer
Guides covering grading, cleaning, food grade vs. industrial, UN markings, buying inspection, drum comparison, rainwater systems, the recycling process, component anatomy, a glossary and an FAQ. Start with grades if you are buying, cleaning if you already own them.

Decision trees
Ten questions that settle most specifications.
Work down the rows. If you can answer these, a supplier can quote you accurately in one pass.
| Question | If yes | If no | Decides |
|---|---|---|---|
| Will a person, animal or edible crop contact the contents? | Food grade or rebottled only | Reconditioned is fine | Grade and documentation |
| Does it ship on a public road under a UN number? | UN-rated assembly, current test date | No marking required | Certification |
| Is the specific gravity above 1.3? | Size down to a 220 | 275 or 330 | Format and handling |
| Will anybody outside your building see the container? | Rebottled | Stained or Grade B units are fine | Cosmetic grade |
| Does your product attack HDPE? | Stainless | Poly | Material |
| Is the fill above 130°F? | Stainless | Poly | Material |
| Do you have a forklift or dock? | Standard delivery | Liftgate, empties only | Freight |
| Is your ceiling under 60 in clear? | 275 or smaller | 330 is available | Format |
| Will you rack them? | Steel base, decked racking | Composite is fine | Base type |
| Will they live outdoors? | Opaque wrap; expect shorter life | Indoors extends service life | Storage |

Resource library questions
Where should I start if I am new to IBC totes?
Start with the grades explained guide and the used IBC tote buying guide. Together they cover what Grade A, B and C usually mean and the twelve-point inspection. Pricing is by quote from partner suppliers.
Is a used IBC tote safe for food or drinking water?
Only with documented food or food-grade prior contents and the right gasket compound, or a new bottle made for food contact. Ask the supplier for documentation and check current regulations for your use. The food grade vs. industrial guide explains the difference.
How do I clean an IBC tote myself?
Identify the residue class first, then run the chemistry that clears it in the right sequence, verify the result and know when to stop. The cleaning guide covers PPE, sequence and the residues that mean the bottle should be replaced, not washed.
Are IBC totes better than 55 gallon drums?
For many liquid-handling jobs, yes: less handling, less floor space and less residue left behind. The comparison guide also lists the cases where drums still win.
Can I use IBC totes for rainwater harvesting?
Yes, and they are well suited to it. Size the system to your roof, add first-flush diversion and an opaque wrap against algae, and protect it from freezing. Check state and local rules before collecting.
