Current 13-sub NMFC density scale

Know your class before the carrier reweighs it

Since July 2025, density sets the class for most LTL freight. Measure the pallet, enter it below, and see where it lands on the scale carriers actually rate from.

Density & class worksheet Awaiting input

Measure the pallet as it ships — including the pallet itself (add about 5.5 in to your height) and any overhang. Weight is the total for all handling units.

← Light & bulky · costs more Dense & compact · costs less →
This is the density class only. Density decides the class for most general freight, but stowability, handling, and liability can override it — hazmat, fragile goods, high-value items, and anything awkward to stack often rate higher than density alone suggests. Verify the NMFC item on your bill of lading before you book. We'll check yours at no charge.
What a wrong class actually costs

Carriers run pallets across dimensioners at the terminal. When the measured class doesn't match the bill of lading, the correction isn't a conversation — it's a rebill.

Immediate The rebill

You pay the corrected class rate plus a reclassification fee, weeks after the freight already delivered and after you've likely invoiced your own customer.

Ongoing Your discount

Repeat corrections signal an unreliable shipper profile. Negotiated discounts get trimmed at renewal, and the increase applies to every lane you run.

Hidden Stale item numbers

The 2025 docket consolidated roughly 2,000 listings. If your system still pulls class from an old commodity table, you may be quoting against an item that no longer exists.

The full density scale

Subprovisions 12 and 13 are new — they reward genuinely dense freight with classes that didn't exist on the old 11-sub scale.
