This Week in Shipping: July 20, 2026

USPS just changed how it prices every box you ship, and Amazon is trying to poach your carrier relationship at the same time.

Between a major DIM weight recalculation, a freight visibility platform splitting in two, and Amazon going after FedEx and UPS customers directly, operators have a lot to digest. Here's what actually matters and what to do about it.

The Top 5 Shipping Stories This Week

1. USPS Lowers Its DIM Weight Divisor, Raising Costs on Larger Packages

Effective July 12, USPS dropped its dimensional weight divisor from 166 to 139. A 12x16x20 box that used to bill at 23 pounds now bills at 28. This brings USPS closer in line with how FedEx and UPS have been rating packages for years.

What It Means for Shippers

If you ship anything bulky but light, your USPS costs just went up, whether or not your actual product weight changed.

• Pull your shipment data and identify which SKUs are getting hit hardest by the new divisor
• Right-sizing packaging is no longer a nice-to-have, it's a direct cost lever
• Rate shop across carriers rather than defaulting to USPS out of habit
• Model the cost impact before your next pricing or margin review, not after

Anyone still packing on autopilot is going to find out the hard way what this costs them.

2. Project44 Splits Into Project44 and LSP44

Project44 has split into two companies. Project44 stays focused on visibility and decision intelligence for enterprise shippers. The new LSP44 targets logistics service providers with an AI-native infrastructure connecting over 5,000 APIs across 282,000 carrier points.

What It Means for Shippers

This is a sign of where the market is heading: platforms are specializing instead of trying to serve everyone with one tool.

• If you're an enterprise shipper, Project44's narrower focus should mean sharper visibility features going forward
• If you work with 3PLs, expect them to move faster once they're running on LSP44's infrastructure
• Evaluate any vendor relationship built on the old combined platform, since the split may change what you're actually getting
• Use this as a prompt to reassess whether your current visibility stack still fits your scale

The bigger lesson here is that generalist tools are giving way to purpose-built ones. Worth keeping in mind for your own stack.

3. Amazon Goes After FedEx and UPS Customers Directly

Amazon is now offering its shipping and storage services to any business, not just sellers on its marketplace. Rates are aggressive, some surcharges are waived, and early adopters like P&G and 3M are already on board. Reports put savings as high as $6 per package for switchers, and FedEx and UPS stock both dropped roughly 10 percent on the news.

What It Means for Shippers

Real competition just entered the carrier market, and that's good news for your negotiating position even if you never touch Amazon's service.

• Use this as leverage in your next FedEx or UPS rate conversation
• Evaluate Amazon Supply Chain Services as a supplement, not necessarily a replacement
• Read the fine print on service levels before committing volume anywhere
• Don't put all your eggs in one carrier basket just because the rate looks good today

More carrier competition means more room to negotiate. Don't let this news pass without picking up the phone.

4. Delaware Port Expansion Faces a Second Lawsuit

The Delaware Container Terminal at Edgemoor is facing another legal challenge, this time from a Philadelphia port operator citing navigation safety concerns. The project recently landed $110 million in state funding to close a cost gap, but the legal fight could still delay it further.

What It Means for Shippers

Port capacity on the East Coast is not expanding as fast as demand is, and legal delays like this push that timeline out further.

• Don't build long-term East Coast fulfillment plans around capacity that isn't live yet
• Keep an eye on congestion risk at existing ports as volume keeps growing into a fixed footprint
• Diversify port usage now rather than waiting for a bottleneck to force the decision
• Track this case if your business has any East Coast import exposure

Infrastructure delays are slow-moving, but they compound. Plan around today's capacity, not tomorrow's promise.

5. C.H. Robinson Flags a Tightening Freight Market

C.H. Robinson's July update points to tighter truckload capacity and rate increases arriving faster than expected. This builds on earlier signs of LTL embargoes in the Midwest and rising spot rates, with geopolitical disruption in the Strait of Hormuz adding further volatility.

What It Means for Shippers

Capacity is getting harder to secure, and waiting until you need a truck to go find one is a losing strategy right now.

• Lock in carrier relationships and capacity commitments before the market tightens further
• Build rate volatility into your freight budget for the second half of the year
• Diversify your carrier portfolio so a single disruption doesn't stall your operation
• Revisit contingency routing plans now, not when you're already stuck

Tight capacity rewards the operators who planned ahead. Everyone else pays the premium.

The Bottom Line

This week is a reminder that cost pressure is coming from every direction at once, pricing mechanics, new competition, infrastructure delays, and capacity constraints. None of these are one-off events. They're structural shifts operators will be dealing with for the rest of the year.

The businesses that come out ahead won't be the ones reacting fastest. They'll be the ones who already rate shopped, already diversified carriers, and already built slack into their fulfillment plans before these pressures hit.

Smart operators are running the numbers this week, not next month.
