July 2025 quietly delivered one of the biggest freight shake-ups in modern memory. The National Motor Freight Classification system went through a sweeping reform that pulled the rug out from under shippers of light, bulky, non-hazardous goods. The old weight-based structure gave way to a density-first model, and if you move items like empty bottles or foam packaging, you’ve probably already seen the damage.

Case in Point: 16 oz PET Bottles

A pallet weighs about 120 pounds but eats up 40 cubic feet of space.

• Old class: 100 before July
• New class: 300 after July

That’s not a minor adjustment. That’s a jump from about $150 to nearly $600 per shipment. A 300–400% spike. The same bottles, the same space, just a radically different bill. That’s not a price adjustment, that’s a mugging, complete with a freight bill as the calling card.

This isn’t just a packaging supplier problem. Every manufacturer, lab, and distributor who relies on lightweight containers is paying more, and those costs don’t evaporate—they roll right down the supply chain. Which means consumers, too, are now paying more for the simple privilege of having their products arrive in something that won’t spill, break, or disintegrate. Add to that the looming tariffs waiting in the wings, and you’ve got the perfect recipe for sticker shock. Freight reform plus trade duties could more than tip the scales, pushing everyday items into price ranges no one expected.

So what now? If you haven’t already called your freight provider, stop waiting for divine intervention. Carriers and 3PLs knew this reform was coming, and many are open to negotiating rates for the higher classes if you get in front of it. Those who wait for the invoice will get no sympathy, only a higher bill. On top of that, audit your freight programs, look at cube utilization, and ask the hard question: is there any way to pack denser? Because the NMFC doesn’t care how cheap your product is. If it floats like a balloon, you’re paying like it’s gold.

This isn’t fearmongering; it’s reality. The freight world changed in July, and the costs are already hitting balance sheets. Combine that with global tariff pressure, and we’re staring at one of the steepest upward cost curves our industry has seen in decades. Companies that plan, negotiate, and adapt will survive it. Those that don’t will be left explaining to customers why an empty bottle suddenly costs as much to ship as a pallet of lead weights.
