The 30-second dashboard
- Shipper demand: Falling. Cass shipments 0.983 in July, minus 2.58 percent from June's 1.009, not seasonally adjusted.
- Inventory pressure: Rising. Inventories-to-sales ratio 1.30 in June, plus 0.02 from May's 1.28, exactly on the band's inclusive edge. Rising is a caution signal, not strength: sales fell 1.1 percent while inventories held.
- Freight cost pressure: Falling. Producer price index for long-distance LTL trucking 293.695 in July, minus 4.63 percent from June's 307.961.
- Supply chain friction: Falling. New York Fed Global Supply Chain Pressure Index 0.805 in July, down 0.380 from June's 1.185. Rising would mean more friction.
- Warehouse labor: Falling. Warehousing and storage employment 1,834.6 thousand in July, minus 0.52 percent from June's 1,844.1 thousand, 9,500 fewer jobs.
The signal
That 0.983 is the weakest July in the Cass shipments series' available FRED history, which begins January 2016, below July 2020's 1.018. It is not an all-time low; January 2026 printed 0.886. Year over year it is minus 4.84 percent.
Fuel moved the other way. EIA put on-highway retail diesel at $5.652 a gallon for the week of 24 August, after $5.454 on 17 August and $5.257 on 10 August: a second straight weekly rise, up $1.07 or about 23 percent from its early-July low of $4.578, and $1.944 above the same week a year ago.
Why it matters to shippers
The freshest measured freight price is a July print and it fell, while the biggest input cost rose in the last two published weeks. The index in a reviewer's head is a month behind the invoice, and surcharges bill off a weekly table. If diesel holds, September lines may reflect it, a forecast not a measurement.
The playbook
- Shipping: check the fuel surcharge on four weeks of freight bills against the table your contract names, and against the week of pickup. At about 20 cents of weekly movement, the wrong week is money.
- Warehouse: warehousing employment fell 9,500 jobs in July, so crews are thinner. No driver leaves before every delivery receipt line is counted and every over, short or damaged quantity noted with a reason.
- Finance and procurement: with volume this soft, confirm open inbound purchase orders still match the demand you expect, and split vendor shortfalls from carrier losses before either becomes a receivable.
One question answered
When is a receiving discrepancy a vendor chargeback, and when is it a carrier claim?
Where the discrepancy was caused decides the counterparty, not who is easier to invoice. Freight that left the vendor correct and arrived short, damaged or delayed is a carrier matter, against the bill of lading and delivery receipt. Freight the vendor never shipped, shipped short, shipped wrong, or shipped non-compliant with the purchase order is a vendor matter, against the PO line and packing slip.
Under 49 CFR Part 370, section 370.3(c) says notations of shortage or damage on delivery receipts, and carrier inspection reports, "shall, standing alone, not be considered by carriers as sufficient" to meet the minimum filing requirements. Writing "2 short" is necessary evidence. It is not a claim.
The vendor side has no equivalent federal regime: a chargeback runs on the buyer-supplier purchase agreement. On timing, 49 U.S.C. 14706(e)(1) bars a carrier from allowing under 9 months to file or 2 years to sue, a floor on a carrier's own terms, not a universal deadline. Timing varies by carrier and by contract or bill of lading, so check the terms governing your shipment. Full breakdown: OS&D Receiving for LTL Freight.
LanePilot field note: detention documentation
Detention is contested on the dock record, not on memory. LanePilot's own read: the log that holds up carries the appointment time, the driver's arrival, the release time, a name against each, and the reason for any delay that was yours, under the receipt's pro and trailer numbers. Timing varies by carrier and contract, so check the terms governing your shipment.
LanePilot's part is the record: over, short and damaged captured line by line against the purchase order at check-in, each with a required reason, and damaged units posted in that status, out of available stock. From a vendor discrepancy it drafts the chargeback letter showing the PO, the expected quantity and what arrived, for the shipper to review and send. LanePilot does not draft or file a carrier claim, and never sends, files or negotiates anything with a carrier or vendor.
