Rebottled vs.
Grade A.
Name the product that goes in the tote. That single answer decides this comparison completely.
One question decides it: does anything edible or potable go in? If yes and you cannot get documented food-grade stock, pay the $185 for rebottled — a brand-new virgin bladder with no fill history. If no, Grade A at $155–$225 is correct and rebottled is money spent on a cleanliness standard you will never use. Cosmetics and “feeling cleaner” are not reasons.
The physical fact underneath
High-density polyethylene is semi-permeable. Over months of service, small molecules from the stored product diffuse into the polymer wall, and over the following months they diffuse back out into whatever goes in next. The effect is small, slow and completely unaffected by cleaning, because cleaning acts on a surface and the residue is in the bulk.
That single fact is the whole comparison. A Grade A unit has a demonstrably sound, clean, pressure-tested bottle — and a history that is now part of the wall. A rebottled unit has a bottle that has held nothing but air.
Side by side
| Measure | Grade A industrial | Rebottled |
|---|---|---|
| Price, 275 gal | $155 – $225 | $340 – $430 |
| Bottle | Reclaimed, washed, tested | New virgin HDPE, FDA-compliant resin |
| Fill history | Documented, non-edible or edible | None |
| Cage | Reclaimed, straightened as needed | Reclaimed, jigged, blasted, zinc-recoated |
| Valve, cap, gasket | Inspected or replaced | All new |
| Pressure tested | Yes, 3 psi air hold | Yes, 3 psi air hold |
| Potable / edible | Only with an edible history (= food grade) | Yes |
| Lead time | 2 – 5 business days | 5 – 10 business days |
| UN rating | No | No |
| CO₂e, cradle to gate | ≈93 lb | ≈110 lb |
| Steel kept in service | 80 lb | 80 lb |
Three cases, decided
Liquid fertiliser on a farm. Non-edible, non-potable. Grade A. Pay $190, not $385, and spend the difference on a UV sleeve and a stand.
Stored drinking water for a rural clinic. Potable. If documented food-grade stock is available, that is cheapest. If it is not — and food-grade 330s in particular are genuinely scarce — rebottled, without hesitation.
A stocked aquaponics system. Potable-equivalent, and unforgiving: a tote that once held a surfactant will leach enough to kill a stocked tank. Food grade with a wash certificate, or rebottled. We will not sell anything else into this application.
The cheapest route of all
If you already own cages — and most operations with a tote fleet do — send them to us. Rebottling your own frames is $185 per unit for a 275, which is below the price of buying a used Grade A unit outright and gets you a never-filled bottle. It also keeps 80 lb of your own steel in service instead of buying somebody else's.
The decision, in one line
Edible or potable? Food grade if available, rebottled if not.
Anything else? Grade A, and keep the $185.
- Price gap
- ≈$185 / unit
- On 20 units
- ≈$3,700
- Rebottle your own cages
- $185 / unit all-in
What a wash cannot fix
- Residue absorbed into the polymer wall
- A missing or illegible data plate
- Stress crazing at a lower bottle corner
- A scored discharge boss face
- A non-food prior content
Let the decoder settle it
Food-grade reuse is on the table.
An edible prior content plus a documented wash is the only path we will sell into potable or edible service. You get the prior-contents record, the wash ticket and photographs of the data plate with the unit.

If Grade A is washed and pressure tested, why would I pay more for rebottled?
Because washing cleans a surface and cannot clean a wall. HDPE is semi-permeable: over months in service, small molecules migrate into the polymer and then slowly migrate back out into whatever goes in next. For industrial fluids that is irrelevant. For drinking water, edible product or a stocked fish tank it is decisive, and no cycle at any temperature reverses it.
So is Grade A ever safe for food?
A Grade A unit whose documented prior contents were edible is what we sell as food grade — that is the same physical object with provenance plus a logged caustic cycle on top. What is never food-safe is a Grade A unit with a non-food history, however clean it is and however well it tests. The grade describes condition; the history describes suitability.
What is the price gap in practice?
About $185 per 275 gallon unit at band midpoints: Grade A around $190, rebottled around $385. If you already own the cages, rebottling your own frames is $185 per unit all-in, which makes it the cheapest route to a never-filled bottle by a wide margin.
Does rebottled have any downside against Grade A?
Two. Lead time — five to ten business days against two to five, because batches are built rather than pulled from stock. And no UN rating, for the same reason a reconditioned unit has none: the marking certifies a tested assembly, and a new bottle in an old frame is a different assembly.
Does anything edible go in it?
Answer that in one word and we will quote the right tier — usually the cheaper one.
