IBC totes for chemical blenders

Chemical blenders and distributors want a steady supply of rebottled or reconditioned 275 and 330 gallon totes for repeat fills, with retest dates current for hazardous liquids. The plate and its dates are the first thing a shipper reads.

The plate before the price

Under 49 CFR 180.352 a liquid IBC needs a leakproofness test every 2.5 years from manufacture or repair, and an inspection on the same schedule. The plate carries the dates. A tote with a lapsed date cannot go back into hazmat service until it is retested, however clean it looks.

The UN plate guide walks the fields, and the retest dates guide lays out the intervals.

Rebottled or reconditioned

A blender whose product reacts to carry-over wants a new bottle, which is a rebottled tote. A blender with a fixed product class and good records may prefer a reconditioned tote, with the wash record. The comparison guide is a one-page decision.

Corona and the West End

Chemical blending in this region clusters near Corona, with distribution in the West End. Neither page names a customer, and nothing here is a promise of stock. The request is how a blender says what size, how many and how often. The Corona page sets out the area.

A blender's week

A blender fills on Monday, ships on Tuesday and receives empties on Friday. The totes that come back vary: some are clean, some carry a skin of product, and some have lost a cap. The cost of a bad one is not the tote; it is the load that arrives with a leak.

Many blenders solve it by keeping two pools. One pool is rebottled totes for sensitive product. The other is reconditioned totes for tougher product classes. Describing your two pools in the request is a short way of saying what you need.

Compatibility is a chemistry question

Polyethylene resists many acids, bases and salts, and is attacked by some solvents and oxidizers. The safety data sheet for your product states compatibility, and the supplier's technical team can confirm it.

Questions people ask

How often is a retest needed?

Every 2.5 years for a liquid IBC, under 49 CFR 180.352.

Can a blender use a tote that held something else?

Only if the old product is compatible; check your SDS and your carrier.
