We make more money per container on Grade A than on Grade B, and considerably more on food grade. So take the following in that spirit: most people buying Grade A should be buying Grade B, and a fair number of people buying food grade should be too.
What Grade B actually is
Washed to a documented procedure. Prior contents recorded. Bottle may have light staining or UV haze. Cage sound with cosmetic dings. Valve serviceable, gasket new. Leak tested and photographed against its serial.
The only functional difference from Grade A is cosmetic: clarity of the bottle and appearance of the cage. Not cleanliness — both grades run the same wash cycle for the same residue class. Not integrity — both are fill-and-hold tested. Not documentation — both carry the prior-contents record.
| Attribute | Grade A | Grade B | Functional difference? |
|---|---|---|---|
| Wash cycle | Per residue class | Per residue class | None |
| Prior-contents record | Documented | Documented | None |
| Leak test | Passed, recorded | Passed, recorded | None |
| New gasket | Yes | Yes | None |
| Bottle clarity | Clear to translucent | Light haze or staining | Cosmetic |
| Cage appearance | Square, clean | Sound, cosmetic dings | Cosmetic |
| Valve | New or near-new | Serviceable | Minor |
| Typical price | $165–$225 | $110–$165 | $55–$60 |
When Grade A genuinely earns its premium
Three cases, and they are real:
- Trace carry-over matters. A pigment, a flavour, a resin system where a tiny amount of residual staining could migrate. Here the clarity of the bottle is genuinely diagnostic — you can see that there is nothing in it.
- The container is customer-facing. If your tote goes to a client's site with your name on it, appearance is part of the product and you should pay for it.
- Inspection or visual level-checking. If somebody needs to read a level through the wall or inspect contents without opening the lid, haze is a functional problem rather than a cosmetic one.
Outside those three, you are buying a bottle you can see through, for a product that is opaque, in a building nobody visits.
The duties Grade B covers comfortably
- Agricultural nutrient storage and fertigation — dedicated per product anyway.
- Spray mix batching, where the container will be rinsed between products regardless.
- Brewery and distillery utility: glycol, caustic, peracetic acid, treated water.
- Municipal brine, anti-icing, hydrant flushing and street-tree irrigation.
- Industrial process water, coolant make-up and wash solutions.
- Latex, emulsion and coating storage, where the product stains any container within one fill.
- Any static storage of a non-hazardous liquid you mixed yourself.
And food grade
Food grade is not a higher grade; it is a different axis. Grade A, B and C describe condition. Food grade describes history — FDA-compliant resin, an edible-only prior-contents record, and a documented wash.
You need it when something downstream is edible, including animal feed. You do not need it because a product is expensive, or because it feels safer, or because the container will be in a food plant but holding a floor cleaner. We sell food-grade stock at a premium because it is genuinely scarce, and we would rather it went to the people who need the record.
How to check yourself
One question, asked honestly: if this container arrived with a slightly hazy bottle and a scuffed cage, but a clean bill on wash, prior contents and leak test — would anything about my process be worse?
If the answer is no, you have a Grade B duty, and there are usually more of them on the ground and they are usually available faster. We will tell you this on the phone, except we do not have a phone, so we tell you in the quote.
