Liquids and slurries need a closed tote with a valve: the SaniTainer has a round inner tank with no corners, ribs or seams to clean, and the Wide Mouth tote has a large lid for mixing and washing. Dry ingredients, produce and meat trim go in open MonsterCombo bins.
Ask for the resin compliance letter for 21 CFR 177.1520 with the quote. That letter, not the word "food grade" on a listing, is what your auditor will request.
Cleaning: a round inner tank drains and rinses faster than a square tote with corners. If you clean in place, tell us your CIP spray device so we match the lid opening.
Stacking and freight: the SaniTainer uses a 46 x 46 in footprint; Wide Mouth totes use 45 x 45 in. Check that against your racks and trailer before ordering.
Volume programs: returnable tote fleets for co-packers and ingredient suppliers are quoted by annual trips, not just units. Tell us your loop and we size the fleet.
