A persistent assumption in tote buying is that freight is going to be the killer expense. It often is for empties, but for filled tanks the math is actually quite favorable, and the reason is the National Motor Freight Classification system.
Class 55 means dense
The NMFC classifies freight on a scale from 50 (densest, cheapest) to 500 (lightest, most expensive). A filled 275-gallon IBC weighing 2,440 lb on a 48"×40" pallet has a density of roughly 23.5 lb per cubic foot, which places it firmly in class 55.
Class 55 is the cheapest LTL class outside of class 50 (which is reserved for bricks and metal ingots). On a typical Midwest LTL lane, the per-pound rate at class 55 is about 35% of what the same lane would cost at class 100 (mid-density freight) and roughly 18% of what it would cost at class 200.
What this means in dollar terms
A full 275-gallon tote moving 350 miles within Tier 1 LTL typically costs $185–$245 to ship. The same pallet at class 100 would cost about $560. The same pallet at class 200 would cost roughly $1,030.
Why empties are harder
Empties ship at class 250 or 300 because density drops to about 1.2 lb per cubic foot — almost all air. That's why our buy-back offers consolidate pickups so aggressively: a single empty tote on a half-empty trailer is unprofitable to move, but eight empty totes consolidated onto a packed half-trailer get back into something rational.
The practical math for buyers
If you're buying reconditioned and the tote ships full of your product anyway, freight is rarely the deciding factor in your buying decision. If you're buying empty (most common for our customers), you should ask for outbound consolidation: do we have a route headed your direction in the next two weeks? Often we do, and you ride along at half the standalone freight cost.
The freight side of the IBC economy is opaque because nobody publishes their consolidation savings. Ask for it explicitly — you'll often get a better number than the first quote.
