Freight math should be checkable.

Why this site exists

Freight class is a pricing input that a shipper has to defend. A calculator that returns a number without the formula, the scale, or the boundary is not much better than a guess. A calculator that returns Class 110 for a 2025 density lookup is worse, because it looks precise while using the wrong table.

We built FreightClassHub around a simple standard: the math should be visible, the scale should be current, and the limits should be stated on the same page as the result. That is why the calculator shows the per-line class, the combined class, the next-tier weight or cube, and a plain-language disclaimer.

How the site is run

• Primary sources first. The density scale and effective date come from the NMFTA. Carrier references are used for measurement and reclass context. Every guide lists its sources.
• No invented credentials. Content is published under the “FreightClassHub editorial team” byline. We do not publish fictional author bios or claim credentials the team does not have.
• No pay-to-play. There are no sponsored calculators, carrier rankings, or affiliate links that change a result. The same inputs produce the same output for everyone.
• Limits are part of the product. Density is one of four classification factors. The NMFC item and the carrier tariff control the final rating. We say so next to the result, not only in a legal footer.
• Corrections are welcome. If a page is wrong, send the URL and the source. Calculation changes are reviewed against the NMFC and carrier references before publishing.

What the site covers

The site includes a pallet weight and cube planner, an LTL linear feet calculator, a freight class and density calculator on the 2025 NMFC scale, and a parcel dimensional weight calculator for UPS, FedEx, and USPS. The reference pages add a printable 2025 class chart and an NMFC commodity lookup, and the guides cover the formulas, the 2025 changes, NMFC codes, and reclass disputes.

Each tool gets its own page, formula, examples, and limits. The homepage is a hub, not a single page holding every calculator.

What the site is not

• Not the NMFTA, and not an official NMFC classification service.
• Not a carrier, broker, or freight forwarder. We do not quote, book, or arrange shipments.
• Not a rate engine. Class is one input to a rate; accessorials, fuel, lane, and tariff rules are outside the calculator.
• Not a substitute for the NMFC item when a commodity-specific class or subprovision applies.

The editorial team

FreightClassHub is written and maintained by an independent editorial team. We keep the byline collective because the work is reviewed as a whole and because we would rather be judged on the cited sources than on a headshot. We do not claim carrier employment or formal NMFC classification credentials.

The site does not publish individual author pages or invented qualifications. If you need to know who reviewed a specific claim, ask and we will tell you what the review was based on.

Contact

Corrections, source suggestions, and calculator feedback go to hello@freightclasshub.com. For shipment-specific classification questions, contact your carrier or the NMFTA — we cannot classify an individual shipment from an email.
