The single most damaging consumer mistake in interstate moving is not paying too much. It is signing a contract that allows the carrier to charge whatever it wants, then arguing about it on delivery day with the trailer parked in your driveway. Federal regulation under 49 CFR Part 375 (the FMCSA's "Transportation of Household Goods in Interstate Commerce; Consumer Protection Regulations") gives consumers significant power, but only if they understand which type of estimate they have.
There are three estimate types under FMCSA rules:
Under 49 CFR 375.401, any written estimate for an interstate household-goods move must:
If your estimate document does not include all of the above, it does not comply with FMCSA rules. That alone is grounds to demand a corrected document or report the carrier to nccdb.fmcsa.dot.gov.
| Feature | Binding | Non-binding | Binding-not-to-exceed |
|---|---|---|---|
| Price at delivery | Fixed at binding amount | Actual tariff cost (capped at 110% collection) | Lower of binding amount or actual |
| Consumer pays more if shipment heavier | No | Yes | No |
| Consumer pays less if shipment lighter | No | Yes | Yes |
| Survey requirement | Strong best practice | Strong best practice | Required by major van lines |
| Carrier risk | Bears upside | Limited | Bears upside only |
| Consumer risk | Bears no upside | Bears full repricing risk | Bears no risk |
| Typical price (vs non-binding) | +2 to +6% | Baseline | +1 to +4% |
| Available from | Major van lines + reputable smaller carriers | All carriers | Major van lines (United, Allied, Mayflower, North American, Atlas) |
| Recommended for | Households that have over-estimated | Households where weight is hard to estimate | Almost all consumers |
This is the most misunderstood consumer-protection rule in the entire FMCSA framework. Under 49 CFR 375.405:
"The carrier may not require payment of more than 110 percent of the non-binding estimate plus charges for legitimate accessorial services not included in the original estimate to deliver the shipment to the destination."
This is NOT a price cap. It is a payment-timing rule. Here is how it works:
The 110 percent rule does not exempt you from owing the full tariff amount; it simply removes the carrier's leverage at delivery. You still owe the additional $3,000 unless you successfully dispute it. The rule's value is procedural: it gives you time and information.
For a binding estimate to be legally enforceable against the carrier under FMCSA rules:
Under 49 CFR 375.403(b), a carrier may amend a binding estimate at the time of pickup only if:
Critically, the carrier may not amend after loading begins. Once goods are on the truck, the binding price is locked. This is why disreputable carriers attempt to renegotiate at the curb just before loading and use the loaded trailer as leverage. Decline to sign any amendment after loading has started; that signature is not legally required.
| Scam | How it works | FMCSA protection |
|---|---|---|
| Low-ball telephone quote | Broker quotes far below market without survey; subcontracts to unscrupulous carrier who reprices at pickup or delivery. | Insist on binding estimate from licensed carrier (not broker) with in-home or virtual survey. Cross-check MC and DOT numbers at safer.fmcsa.dot.gov. |
| Hostage loading | Carrier refuses to deliver until consumer pays inflated amount. | 110% rule (49 CFR 375.405); file FMCSA complaint at 1-888-368-7238 if violated. |
| Inventory tampering | Carrier adds bogus items to inventory at pickup to justify weight increase. | Photograph and inventory your shipment yourself; refuse to sign inventory with items you did not present. |
| Phantom shuttle charge | Carrier claims shuttle was required when trailer could in fact access. | Photograph street access during survey; demand carrier document need for shuttle with photos and measured distance. |
| Estimate signed after loading | Carrier presents "amendment" to binding estimate after loading begins. | Loading-then-amendment is not legally enforceable under 49 CFR 375.403. |
| Subcontracted truck | Brand on truck differs from name on contract; goods go to unknown carrier. | Verify DOT number on truck matches the carrier on the bill of lading; refuse pickup if mismatch. |
When comparing quotes from multiple carriers, the headline binding amount tells you only part of the story. Normalize using this checklist:
The Order for Service is the document you sign that authorizes the move and converts the estimate into a contract. It must contain:
The Bill of Lading is the contract for transportation. It must include or reference all the Order for Service items plus:
Critical practice: at delivery, walk through every room with the inventory list. Note any damage or missing items on the bill of lading before signing. Signing a clean bill of lading at delivery makes claims much harder; carriers will argue any damage noted later happened post-delivery.
You have nine months from delivery to file a claim for loss or damage under 49 CFR 370. Steps:
If you do nothing else from this guide, do this: insist on a binding-not-to-exceed estimate from a regulated van line whose salaried estimator has performed an in-home or live video survey of every room you intend to ship from, with the inventory attached to the estimate and a delivery spread written into the Order for Service. Refuse to sign any amendment after loading begins. Photograph every item before pickup and walk the inventory at delivery before signing the bill of lading. Decline to pay any amount above the binding figure at delivery; demand that disputed amounts be billed under the 110 percent rule. This single paragraph would eliminate the vast majority of consumer complaints in the FMCSA database.
A binding estimate is a fixed-price contract: you pay the quoted amount regardless of actual weight or cube. A non-binding estimate is an opinion of cost based on the carrier's tariff: you pay the actual tariff cost calculated after the shipment is weighed. Federal regulation (49 CFR 375.401) requires interstate carriers to clearly mark which type of estimate they are providing on the document itself.
Binding-not-to-exceed is the strongest consumer-protection estimate type. The carrier guarantees a maximum price (the binding figure) but charges less if the actual weight or cube turns out to be lower than estimated. It combines price certainty with the upside of paying less if you over-prepared. As of 2026, all major van lines (United, Allied, Mayflower, North American, Atlas) offer binding-not-to-exceed estimates when a salaried estimator surveys the shipment.
Under 49 CFR 375.405, on a non-binding estimate the carrier may not require payment at delivery of more than 110 percent of the non-binding estimate plus charges for legitimate accessorial services not included in the original estimate. Any amount above 110 percent must be billed and collected within 30 days. This is not a price cap; it is a payment-timing rule that limits leverage at delivery.
In limited circumstances, yes. If you add items to the shipment, change services requested, or the access at origin or destination differs from what was surveyed (e.g., long carry, shuttle), the carrier is permitted under 49 CFR 375.403 to amend the binding estimate. The amendment must be in writing, signed before loading begins, and must specify the new amount. A carrier cannot unilaterally reprice a binding estimate without your written agreement.
Under FMCSA rules: written estimate (binding or non-binding) before signing; Order for Service (49 CFR 375.501); Bill of Lading (49 CFR 375.505); inventory of items (high-value declaration if applicable); FMCSA pamphlet 'Your Rights and Responsibilities When You Move' and 'Ready to Move' brochure (49 CFR 375.213). Refusal to provide these or providing them after pickup is a federal violation reportable to nccdb.fmcsa.dot.gov.
Not technically. Federal rules allow a virtual or live-video survey to qualify as the basis for a binding estimate. They also allow a phone or email-only estimate, but only the major reputable van lines will offer a binding estimate without some form of visual survey. If a salesperson offers a binding quote without seeing your goods in any form, expect a renegotiation attempt at pickup or destination.
You pay only the binding amount, regardless of actual weight. The carrier absorbs the difference. This is why some unethical carriers refuse to give binding estimates, or give a low-ball binding estimate then attempt to charge an amended price at pickup. Always read the estimate document; the word BINDING or NON-BINDING must appear prominently.
You pay the binding amount. The carrier keeps the difference. This is why a binding-not-to-exceed estimate is superior: it caps the maximum at the binding figure but reduces the price if actual weight is lower. Some carriers offer 'binding-not-to-exceed' only when a salaried estimator performs the survey, since it shifts pricing risk to the carrier.
No. Under 49 CFR 375.405, on a non-binding estimate the carrier may collect only 110 percent of the estimate at delivery; the balance is billed within 30 days. On a binding estimate they may collect the full binding amount. If a carrier refuses to deliver until you pay more than 110 percent of a non-binding estimate or more than the binding amount, that is hostage-loading, a federal violation reportable to FMCSA at 1-888-368-7238.
