Used IBC Totes — 275 & 330 gallon, your grade.

Grade A (food). Previous contents documented as food-only (corn syrup, glycerin, fruit purees, food ethanol, etc.). Four-stage wash: cold soak, 145°F caustic flush with rotating spray, two cycles of 165°F potable rinse, 36-hour air dry. Final discharge pH 7.0–7.6 recorded on the tote tag. ~80 units in stock at any time.

Grade B (industrial washed). Two-stage caustic + potable rinse at 140°F / 160°F. Suitable for first-fill of industrial chemistries, lubricants, coolants, non-food brewing ingredients, agricultural fluids, surfactants. ~80% of our resale volume. ~90 in stock.

Grade C (rinsed). Single cold-water flood and drain. Appropriate for non-contact uses: rainwater harvesting, secondary spill containment, gravel ballast, raised garden beds, repurposing. Cheapest and most plentiful.

Every tote leaves with a tag: internal ID, manufacture year, grade, previous contents, wash protocol, wash date, technician initials, and (for Grade A) discharge pH from final rinse.

Bottles with unknown previous contents go to Grade C only — never Grade B or A regardless of how clean they look. We've turned away truckloads of "untraceable" inventory and we don't apologize for it.

Bottles with cracks in the wall, cracks at the outlet boss, or cage welds that have failed are scrap. We don't field-patch these and we don't sell them with a "use at your own risk" disclaimer. They go to the HDPE pellet stream and the cage to scrap steel.

Bottles that previously held aromatic solvents (xylene, toluene), chlorinated compounds (TCE, methylene chloride), or strong oxidizers do not return to fluid service in our yard. Even with hot washing, residual permeation is detectable. They go to controlled HDPE recycling streams that don't include food or potable end-use.

Composite IBC bottles are typically rated by manufacturers for 8–10 years of refurbishable life from date of manufacture. We retire bottles from active service at 12 years regardless of condition — the HDPE has accumulated enough thermal and UV cycles that mechanical properties drift below where we're comfortable selling. The cage usually outlives the bottle by 2–3× and gets re-paired with newer bottles.

You can find the manufacture year stamped or molded inside the top hatch ring on most bottles. Schutz, Mauser, and Werit all use a standard ISO format. Snyder uses an internal sequential number that requires our reference binder to decode.
