How do you dispute an LTL freight overcharge under 49 U.S.C. § 13710?
You dispute an LTL overcharge under 49 U.S.C. § 13710 by contesting the bill in writing within 180 days of receiving it, the deadline the statute sets for a shipper to preserve the right to challenge a charge. Miss that window and the carrier can treat the bill as final, regardless of whether the charge was actually correct.
Most shippers who catch a billing error know something is wrong with the invoice. Far fewer know that federal law gives them a specific, named right to contest it, under a specific statute. This guide covers what 49 U.S.C. § 13710 actually says, how it interacts with the separate 18-month deadline in 49 U.S.C. § 14705, and what your legal footing is once you decide to file. LanePilot is a shipper-side rate comparison and invoice audit tool, not a freight broker TMS. It identifies the discrepancy and drafts the dispute letter; you remain the party who files it.
What 49 U.S.C. § 13710 actually says
49 U.S.C. § 13710, titled "Additional billing and collecting practices," governs how a motor carrier of property, other than a household goods carrier or a carrier in noncontiguous domestic trade, is allowed to bill and collect charges from a shipper. It does two things that matter directly to an LTL overcharge dispute.
It declares certain billing practices unreasonable
The statute gives certain billing practices the legal status of an "unreasonable practice." When the applicability or reasonableness of the rates and charges billed by a motor carrier is challenged by the party paying the freight bill, the Surface Transportation Board has jurisdiction to determine whether those rates and provisions are reasonable. That is a real legal mechanism: a billing dispute under this statute is a dispute about whether the carrier's charge complies with the law, not a request for a favor.
It sets a mutual 180-day window
Subsection (a)(3) sets the clock that controls almost every LTL billing dispute in practice:
- Carrier side, § 13710(a)(3)(A): a carrier must issue any bill for charges in addition to those originally billed within 180 days of receiving the original bill, in order to have the right to collect those charges.
- Shipper side, § 13710(a)(3)(B): a shipper must contest the original bill or a subsequent bill within 180 days of receiving it, in order to have the right to contest the charges.
Read together, this is a symmetrical rule. A carrier that sits on a reweigh or reclassification for more than 180 days loses the right to collect the difference. A shipper who sits on a suspected overcharge for more than 180 days loses the right to contest it. The statute does not care which side was busy; it only cares whether the bill was contested inside the window.
Why the 180-day window is the deadline that matters
The 180-day period is a right-preserving deadline built directly into the billing statute itself, not a carrier courtesy policy. It is the mechanism by which the right to contest a bill exists at all under § 13710(a)(3)(B). Once it passes, a carrier's claims department has a straightforward, statute-backed basis to deny a late-filed dispute regardless of how clear the underlying error is. That makes an unreviewed invoice backlog expensive in a literal sense: every invoice sitting unaudited is a 180-day countdown against your own legal right to contest it. Our guide to auditing an LTL freight invoice covers how to catch the error itself; this post is about the legal clock once you have.
The separate, longer deadline: 49 U.S.C. § 14705
A second statute, 49 U.S.C. § 14705, sets an entirely different deadline that shippers sometimes mistake for their real filing window. It should not be treated that way.
What § 14705 covers
Section 14705(b) sets an 18-month statute of limitations for a person to begin a civil action to recover overcharges. Under § 14705(g), that claim accrues on delivery or tender of delivery by the carrier, not on the invoice date, so the 18-month clock and the 180-day clock in § 13710 do not start from the same event.
Section 14705(d) adds an important extension: if a written claim is submitted within the applicable limitations period and the carrier disallows all or part of it, the deadline to file suit extends 6 months from the carrier's written notice of disallowance. That extension only helps if you already filed a written claim, which is exactly why filing early and in writing matters regardless of which deadline you track.
Why 180 days, not 18 months, is your real target
The 18-month period in § 14705 is the outer legal boundary for going to court, not a practical filing target. A carrier's claims department will apply the 180-day rule from § 13710 to a shipper-initiated dispute long before an 18-month litigation deadline is ever relevant. File within 180 days of the invoice; treat 18 months only as the backstop you should never need.
Filing a claim: what the regulations require
Once you have identified the overcharge, 49 CFR § 378.4 sets the baseline documentation requirement: an overcharge claim must be accompanied by the freight bill, plus enough detail, such as the applicable rate, classification, weight, or tariff authority, for the carrier to investigate it. In practice, your written dispute should include:
- The freight bill (invoice) showing the disputed charge
- Your original quote or contracted rate, to show what should have been billed
- The specific rate, classification, or weight figure you are disputing, stated as a number, not a general objection
- The dollar amount of the refund you are seeking
If you have not yet written the letter itself, our LTL freight dispute letter template covers the exact structure and language to use once your documentation is together; this post exists to make sure you understand the legal basis and deadline behind that letter before you send it.
What your legal footing actually is as a shipper
49 U.S.C. § 13710 makes certain carrier billing practices legally unreasonable and gives the Surface Transportation Board jurisdiction to rule on rate disputes. Filing a timely, documented dispute is exercising a right written into the U.S. Code, not asking for a favor. The villain here is never a carrier acting in bad faith; reweighs happen, classification shifts happen, and accessorial codes get applied by whoever is on the dock that day. The real cost comes from errors nobody checks and disputes nobody files before the clock runs out.
What LanePilot does and does not do
LanePilot compares your LTL invoices against your original quotes to identify discrepancies in class, weight, accessorials, and fuel surcharge, and drafts a dispute letter that cites the relevant statute and includes the documentation a carrier's claims department needs to investigate the charge. LanePilot does not hold a freight brokerage license, and does not send, file, or negotiate the dispute with the carrier on your behalf. You remain the party of record under § 13710, and file the claim yourself. If you want to see whether your own invoices carry a disputable overcharge, you can run a free audit or read more about how LanePilot works.
Frequently Asked Questions
What does 49 U.S.C. 13710 actually say?
49 U.S.C. 13710 is titled "Additional billing and collecting practices." It makes certain motor carrier billing practices legally unreasonable, gives the Surface Transportation Board jurisdiction to decide rate-reasonableness disputes, and sets a mutual 180-day window: a carrier must issue additional charges within 180 days of its original bill, and a shipper must contest a bill within 180 days of receiving it, or lose the right to do either.
Does 49 U.S.C. 13710 apply to LTL freight specifically?
Yes. The statute applies to motor carriers of property, which includes LTL carriers, and its billing-dispute provisions carve out household goods carriers and carriers in noncontiguous domestic trade (e.g., Alaska, Hawaii, Puerto Rico). Domestic LTL invoice disputes over freight class, weight, accessorials, and fuel surcharges fall squarely within the billing practices the statute governs.
What is the actual deadline to dispute an LTL overcharge?
Two different deadlines apply. Under 49 U.S.C. 13710(a)(3)(B), you have 180 days from receipt of the bill to contest it, which is the practical deadline carriers hold shippers to. Separately, 49 U.S.C. 14705(b) sets an 18-month statute of limitations to file a civil action to recover an overcharge, running from delivery or tender of delivery. Treat 180 days as your real deadline; the 18-month period is a legal backstop, not a filing target.
What happens if I file a claim and the carrier denies it?
Under 49 U.S.C. 14705(d), if you submit a written claim within the applicable limitations period and the carrier disallows part or all of it, your deadline to file a civil action extends 6 months from the date of the carrier's written notice of disallowance. Keep the disallowance letter; it is what triggers the extension.
Can LanePilot file my dispute with the carrier for me under this statute?
No. LanePilot is a shipper-side rate comparison and invoice audit tool, not a freight broker TMS, and it holds no brokerage license. It identifies the overcharge and drafts the dispute letter citing the relevant statute, but the shipper remains the party of record and files the claim themselves.
