What Freight Class Are Used Bulk Bags?

🚚 Save BIG on Truckload orders!

“What freight class are used bulk bags?” sounds like it should have one clean answer.

It doesn’t.

Because freight class (for LTL especially) isn’t really about what the item is… it’s about how it ships.

Used bulk bags can ship as:

• a loose, fluffy pallet that takes up a ton of space but weighs almost nothing, or

• a tight, compressed bale that’s dense and easy to handle.

Same product. Two totally different freight classes.

So the real answer is:

Used bulk bags are usually classed based on density and how they’re packaged, and they commonly land somewhere in the “middle-to-higher” freight class range if they’re light/fluffy… and lower if they’re baled tight and dense.

Let’s break it down in plain English so you can quote it right, avoid reclass fees, and stop getting surprised by carriers.

What “Freight Class” Actually Means (In the Real World)

Freight class is an LTL pricing system (NMFC) that basically asks:

“How annoying is this shipment for the carrier?”

They look at:

• Density (weight per cubic foot)

• Handling (easy to move vs awkward)

• Stowability (does it stack well? does it waste space?)

• Liability (damage risk, claims risk)

Used bulk bags tend to be:

• lightweight for the space they take up (unless compressed)

• easy to handle when palletized

• not fragile (usually)

• but they can be bulky as hell

So density is usually the #1 driver.

The Big Truth: There Is No Single Freight Class for Used Bulk Bags

If anyone tells you “Used bulk bags are always Class ___,” they’re guessing.

Carriers reclass freight every day based on the actual footprint and the actual weight on the dock.

That’s why one month you ship the same “100 used bags” and it bills fine… then next month you ship another pallet and get hit with:

• reclass

• inspection fees

• “corrected” charges

Nothing changed except how tight you packed it and how tall it stood.

---

The Typical Freight Class Range You’ll See for Used Bulk Bags

Here’s what happens most often:

1) If they’re tightly baled / compressed

Used bulk bags shipped as compressed bales (strapped, tight, minimal air) usually come in at a lower class because the density is higher and the shipment is more stowable.

Common “baled textile / baled bags” style shipments often end up in the Class 70–125-ish neighborhood depending on density and carrier interpretation.

2) If they’re palletized but still fluffy (not compressed)

Used bulk bags shipped as a standard pallet (stacked, but still full of air) tend to be less dense.

Those often land in the Class 150–250-ish neighborhood, again depending on the final density.

3) If they’re loose, awkward, oversized, or unstable

If they’re not wrapped well, not stackable, or take up a ton of cube, you can see them pushed higher (Class 250–400+), especially if the pallet is tall, light, and “squishy.”

So when someone asks “What class are used bulk bags?” the best honest answer is:

Usually somewhere between Class 70 and Class 250+ depending on compression and density.

---

Why Used Bulk Bags Get Reclassed So Often

Because people ship them like this:

• one pallet has 100 bags compressed tight (dense)

• the next pallet has 100 bags “stacked nicely” but full of air (fluffy)

• both are called “used bulk bags”

• both get entered at the same class

• carrier inspects the second one and says: “Nope.”

Used bulk bags are basically a freight class “trap” because:

• they compress

• they expand

• and the cube swings wildly based on how the warehouse guy stacked them that day.

---

The Only Reliable Way to Class Used Bulk Bags: Density

If you want accuracy, you do it like this:

Step 1) Measure the shipment (including pallet)

Length × Width × Height (in inches)

Step 2) Get cubic feet

(L × W × H) / 1728 = cubic feet

Step 3) Weigh it (including pallet)

Total lbs

Step 4) Calculate density

Total lbs / cubic feet = lbs per cubic foot

That density then maps to a class range.

That’s how brokers and carriers price LTL correctly.

And yes — this is exactly why two “identical” used-bag pallets price differently.

---

A Realistic Example (So This Clicks)

Let’s say you ship a pallet of used bulk bags:

• Pallet footprint: 48″ × 40″

• Pallet height: 84″ (7 feet tall)

• Total weight: 850 lbs (bags + pallet)

Cubic feet:

• 48×40×84 = 161,280 cubic inches

• 161,280 / 1728 = 93.33 cubic feet

Density:

• 850 / 93.33 = 9.1 lbs/ft³

That density is not terrible. That will usually get a midrange class.

Now imagine you don’t compress them and the pallet height becomes 96″ (8 feet tall), same weight:

• 48×40×96 = 184,320 cubic inches

• /1728 = 106.67 cubic feet

Density:

• 850 / 106.67 = 7.97 lbs/ft³

Just by making the pallet taller (more air), you dropped density… and class can move.

That’s why storage guys “doing you a favor” by stacking taller can cost you money.

How to Get a Lower Freight Class on Used Bulk Bags (Legally)

If you want to keep your freight class down, you don’t beg the carrier.

You change the shipment characteristics:

1) Compress / bale them tighter

• Strap them tight

• Use stretch wrap aggressively

• Reduce height

• Reduce “air”

2) Keep them stackable

Carriers hate freight that can’t be stacked.
If your pallet is mushy, leaning, or uneven, they price it like a problem.

3) Use standard pallet sizes

48×40 is your friend.

4) Avoid weird overhang

Overhang = stowability penalty = class pain.

5) Label it clearly and consistently

If your BOL says something vague like “used bags,” you increase the odds of inspection/reclass.

---

What to Put on the BOL (So Carriers Don’t Get Cute)

You want your description to be:

• accurate

• clear

• consistent

• matched to how it’s packaged

Good descriptions look like:

• “Used FIBC bulk bags, palletized, shrink-wrapped”

• “Used polypropylene super sacks, compressed/baled, palletized”

• “Used bulk bags, baled, strapped, NMFC item (if known), non-hazardous”

Avoid:

• “bags”

• “miscellaneous”

• “plastic”

• anything that sounds like you don’t know what you’re shipping

Because vague descriptions invite reclass.

LTL vs Truckload: Why Truckload Often Wins for Used Bulk Bags

Used bulk bags are light per cube unless compressed.

LTL charges for:

• class

• space

• terminals

• handling

• reweigh

• reclass

Truckload is more about:

• trailer space

• origin/destination lane

• fuel market

So once you start shipping multiple pallets of used bulk bags, LTL can get stupid expensive.

If you’re moving volume, truckload (or partial) frequently becomes cheaper and more predictable—especially if you can fill space efficiently with compressed bales.

“What Class Should I Quote Customers?” (Practical Answer)

If you’re quoting freight regularly and need a repeatable baseline, here’s the smart move:

Option A: Quote as a range

“Freight class typically falls between ___ and ___ depending on compression and pallet height.”

Option B: Standardize your packaging method

If you always ship:

• 100 bags per pallet

• same wrap

• same strap

• same target height

• same average weight

Then you can quote a consistent class because you’ve made the density consistent.

Most freight problems disappear when you standardize packaging.

Why “Used” Matters (From a Freight Perspective)

Used bulk bags may have:

• irregular folds

• inconsistent stacking

• varying amounts per pallet (80 today, 120 tomorrow)

• different bag types mixed (baffle, duffle, liners, etc.)

That creates inconsistent cube and weight.

So if you’re trying to keep freight class predictable:

• don’t mix bag types in one pallet

• keep counts consistent

• compress the same way every time

---

Quick “Rule of Thumb” Cheatsheet

If you don’t want the math every time, use this mental model:

• Tightly compressed / baled pallets → lower class (better pricing)

• Fluffy tall pallets → higher class (worse pricing)

• Loose/unstable/oversized → even higher class + reclass risk

And the more consistent your pallet build is, the fewer surprises you get.

---

Bottom Line

Used bulk bags don’t have one fixed freight class.
They’re typically classed based on density and packaging, and they often fall somewhere in the Class 70 to 250+ range depending on whether they’re compressed/baled or fluffy/palletized.

If you tell us:

• how many bags per pallet,

• your typical pallet height,

• and the average pallet weight,
  we can help you dial in a consistent shipping setup that keeps your freight class (and your freight bill) under control.
