Moving Weight Tickets: The Re-Weigh You Can Demand

A weight ticket carries three numbers, printed one under the other on a slip small enough to lose:

GROSS   34,180 lb
TARE    26,940 lb
NET      7,240 lb

Only the bottom number is your property, and it is the one a re-weigh can still change. The top two are a truck, and between them they decide what the move costs on a non-binding estimate. Push the tare up by 300 pounds and the net falls by 300; push it down by 300 and your bill grows by the same amount, without a single box changing hands. Nothing on the slip announces which of those things happened. The slip just prints subtraction.

What follows is how those two weighings are supposed to be taken, what has to be sitting on the truck when each one happens, the six things the ticket must say, and the exact window in which a re-weigh can still be demanded — which closes earlier than most people expect. All of it is interstate: a move crossing a state line, governed by 49 CFR Part 375. A move that starts and ends inside one state is a matter of state law and none of this reaches it. Quotations below are the Part 375 text as issued on the eCFR for 18 August 2026, pulled and read on 21 August 2026. One reading note before any of it makes sense: throughout Part 375, "you" means the mover. Section 375.103 says so — "You and your means a household goods motor carrier engaged in the interstate transportation of household goods and its household goods agents." Every "you must" quoted below is an obligation on the company.

Two weighings, one subtraction, and where the slack lives

First, whether any of this applies to your move. Section 375.507 ties weighing to the kind of estimate you signed: when a mover transports on a non-binding estimate "dependent upon the shipment weight," it must determine the weight of each shipment before assessing any charges, and it must weigh on a certified scale. The booklet is blunter about the other case — if your mover provided a binding estimate, "the weight of the shipment will not affect the charges you will pay, so there is no requirement to weigh shipments moving under binding estimates." Which kind you hold decides whether the rest of this page is about you at all, and that distinction is its own subject: binding, non-binding and not-to-exceed on delivery day.

Section 375.509 allows exactly two methods, and the difference between them matters later:

• Origin weigh (first method). Tare the vehicle before loading at origin, gross it after loading, subtract.
• Back weigh (second method). Gross the loaded vehicle at destination, tare the same vehicle after unloading, subtract.

Both are differences, not measurements. That is the structural point the whole page turns on. Anything sitting on the truck at both weighings cancels out — another family's shipment already loaded on a consolidated trailer does not distort your net weight, provided it is aboard for both. Anything that appears or disappears between the two does not cancel, and lands entirely on your number.

Two variations sit beside the main rule. Under 375.509(d), shipments moved in containers use net weight: the difference between the tare weight of the container "including all pads, blocking and bracing used in the transportation of the shipment" and the gross weight of the container with the shipment loaded. And 375.511 lets a shipment of 3,000 pounds or less (1,362 kilograms or less) be weighed on a platform or warehouse certified scale before loading or after unloading, instead of on a vehicle scale.

What must be aboard at tare, and who must be off it

Paragraph (b) of 375.509 lists three conditions that "must exist for both the tare and gross weighings." Read them as a list of the ways a net weight goes wrong.

All the equipment must be on the truck. Section 375.509(b)(1): the vehicle "must have installed or loaded all pads, dollies, hand trucks, ramps, and other equipment required in the transportation of the shipment." Blankets, straps, ramps, the two-wheelers — that gear belongs to the mover and it weighs something. Off the truck at tare and back on at gross, and its weight has been added to your shipment. A full set of moving pads on a long-haul trailer is not a rounding error.

No people. Section 375.509(b)(2): "The driver and other persons must be off the vehicle at the time of either weighing." A driver and a helper aboard for the tare and off for the gross would inflate your net weight by roughly their body weight, and nothing on the printed ticket would show it.

Fuel. Section 375.509(b)(3) requires full tanks at each weighing, with one alternative: on an origin weigh where the tare comes first, the mover "must refrain from adding fuel between the two weighings." Diesel runs about seven pounds per gallon, so a single 100-gallon top-up between an empty tare and a loaded gross drops roughly 700 pounds of fuel inside your net weight. No weight ticket records a fuel stop, and no arithmetic on the slip will surface one, which makes this the one condition of the three you cannot check from the paperwork alone. The checkable version is a written question to the mover: were the tanks full at both weighings, or was fuel withheld between them? Paragraph (b)(3) is where that obligation comes from, and it allows no third answer.

One more from 375.509(c): a tractor-trailer may be uncoupled and the trailer weighed separately at each weighing, but only where the scale platform is long enough to accommodate and support the entire trailer at one time. Two weighings of the same trailer, tractor attached for one and detached for the other, are not the same subtraction.

Six things the ticket must say, and what each one catches

Section 375.519 requires a weight ticket for every weighing, each signed by the weigh master, each carrying six items. Held against your own paperwork, each item catches something specific.

1. Complete name and location of the scale. Look at where it is. A tare taken 90 miles from your origin, on a route that makes no sense for the day, is worth a question.
2. The date of each weighing. The tare should belong to the day of your load, not to whatever the truck last did. Two tickets dated four days apart describe a vehicle in two different states of fuel and gear.
3. Identification of each entry as tare, gross or net. An unlabelled column of figures does not satisfy this.
4. Company or carrier identification of the vehicle. This is the cross-check almost nobody runs. Section 375.505(b)(9) requires the bill of lading to carry "the company or carrier identification number of the vehicle(s) upon which you load the individual shipper's shipment." The same field, on two documents, required by two different rules. If the truck number on the weight ticket is not the truck number on your bill of lading, the tare was taken on something other than the vehicle your furniture rode in. Which document settles what, and when, is laid out in the four documents in an interstate move.
5. Your last name as it appears on the bill of lading.
6. The carrier's shipment registration or bill of lading number.

Then 375.519(d), the paragraph with teeth: all freight bills presented to an individual shipper "must include true copies of all weight tickets obtained in the determination of the shipment weight in order to collect any shipment charges dependent upon the weight transported." An invoice carrying a weight with no tickets behind it has not met the condition the rule attaches to collecting that charge.

"Certified scale" is defined in 375.103 as a scale "inspected and certified by an authorized scale inspection and licensing authority," designed for weighing motor vehicles, or a platform or warehouse type scale. In practice that authority is a state weights-and-measures programme applying NIST Handbook 44, whose current edition is 2026. Worth knowing: the scale operator keeps its own copies. The CAT Scale network common at truck stops states in its FAQ that it holds an electronic record of every ticket sold for seven years and will supply a copy on request, and that printed tickets are legal documents it will not alter. When a ticket is missing from your file, the scale is a second place to ask.

The notification that opens the window

Here is the interlock that makes the next section usable, and it works only if you ask for it in advance. Section 375.521 says that where a shipper on a collect-on-delivery basis "specifically requests notification of the actual weight or volume and charges on the shipment," the mover must comply, conditioned on your supplying an address or telephone number. Under (b), you must receive that notification at least one full 24-hour day before any tender of the shipment for delivery, excluding Saturdays, Sundays and Federal holidays.

Paragraph (c) lists three circumstances in which the 24 hours may be disregarded: the shipment will be back weighed at destination; pickup and delivery encompass two consecutive weekdays and you agree; or the shipment moves under a non-binding estimate with delivery-day payment capped at 110 percent of the estimated charges and you agree to waive the notification. The third is a waiver, and it tends to be presented as a formality on a form. It is the day of advance warning you would otherwise have had.

Demanding the re-weigh, and the minute it stops working

Section 375.517 is two sentences long:

After you inform the individual shipper of the billing weight and total charges and before actually beginning to unload a shipment weighed at origin (first method under 375.509(a)(1)), the individual shipper may demand a re-weigh. You must base your freight bill charges upon the re-weigh weight.

Three limits are packed in there. The right opens after you have been told the billing weight and total charges, which is what 375.521 exists to produce. It closes when unloading actually begins — not when the truck leaves, not when you sign, not when the invoice arrives. And it belongs to shipments weighed at origin. Once the tailgate is down and the first item is off, that particular argument is finished.

The booklet supplies the two commercial terms: the mover "is not permitted to charge you for the reweighing, but the final charges due will be based on the reweigh weight, even if it is more than the initial weight." Free, and binding in both directions. If your suspicion is wrong, the higher number becomes the billing weight.

Running alongside it, 375.513 gives the shipper — or anyone else responsible for paying the freight charges — the right to observe all weighings, and obliges the mover to say where and when each will occur and to give a reasonable opportunity to be present. On waiving that right, the two halves of Part 375 do not read alike, and it is worth knowing before somebody tells you what your absence cost. Section 375.515 presumes waiver of an ordinary weighing if a shipper simply elects not to attend, and requires waiver in writing only for a re-weighing. Appendix A says instead: "You may waive your right to observe weighing; however, you must waive that right in writing." Same part, two formulations, and the regulation is the operative text. What settles the practical question is 375.515(c): waiver of the right to observe a weighing or re-weighing "does not affect any other rights of the individual shipper under this part or otherwise." Missing the origin weighing does not cost you the re-weigh.

Where the new number lands on your bill

A re-weigh changes the weight. It does not change the ceiling. Those are separate mechanisms, and running them together is how people talk themselves out of asking.

The ceiling comes from 375.405(b)(8): once a shipment is loaded, failure to execute a new non-binding estimate signifies the original has been reaffirmed, and the mover "may not collect more than 110 percent of the amount of the original non-binding estimate at destination," subject to the additional-services and impracticable-operations carve-outs. Section 375.703(b) states the same figure as the maximum collect-on-delivery amount, and 375.407(a) turns it into an obligation: pay up to 110 percent and the mover must relinquish possession at the time of delivery. That number is computed from the estimate. Weight has nothing to do with it.

What weight sets is the tariff charge sitting underneath the ceiling. Line-haul on a household goods tariff is normally quoted per hundredweight — 100 pounds, written cwt — against a distance. So a 400-pound correction is four hundredweight, the rate per cwt is on your estimate, and the multiplication tells you what is actually at stake before you decide whether to hold up a delivery. The rest of the sheet follows different rules, which is a separate exercise in reading a moving quote line by line.

Weight does two more jobs worth knowing about. Where a shipment is partially lost or destroyed, 375.707(a)(1)(i) holds the delivery-day demand to "the percentage of the weight of that portion of the shipment delivered relative to the total weight of the shipment," and 375.707(b) makes the mover establish that proportion "based on actual or constructive weight" at its own expense — not you, and not out of your charges. Section 375.407(c) applies the same weight ratio to an ordinary partial delivery. Either way the fraction is assembled out of weights, which is a second reason the tickets are worth keeping. And the booklet closes a gap at the bottom end: where a mover fails to advise you of its minimum charges and your shipment comes in under the minimum weight, "your mover must base your final charges upon the actual weight, not upon the minimum weight."

What to say at the truck, and what to have in your hand when you say it

The demand itself is short. Said at the door, before anything comes off:

I am demanding a re-weigh of this shipment under 49 CFR 375.517, before unloading begins. Please do not begin to unload. I also intend to observe the re-weighing under 375.513 — tell me the scale and the time.

Then send those same two sentences to the mover's office by email or text, timestamped, before the crew starts work. A demand that exists only as something said in a driveway is a demand two people will later remember differently.

Have four things reachable — on a phone is fine — before delivery day rather than during it:

• The bill of lading. Item (9) is the carrier identification number of the vehicle and item (11) is the maximum amount that may be demanded at delivery. Those are the two numbers you will end up reading aloud.
• Copies of every origin weight ticket, which 375.519(d) requires to accompany the freight bill. If none were supplied, asking for them is itself the first thing to put in writing.
• Whatever reached you as the 375.521 notification of actual weight and charges. Keep the date and time it arrived — the re-weigh right opens from that moment, not from the truck's.
• The signed non-binding estimate, for the rate per hundredweight and for the figure the 110 percent is calculated from.

If a mover refuses a re-weigh demanded inside that window, or refuses to release a shipment after you have offered up to 110 percent, the complaint route is the FMCSA National Consumer Complaint Database at nccdb.fmcsa.dot.gov or 1-888-368-7238, and 375.407(b) treats a refusal to relinquish as a failure to transport with reasonable dispatch, exposing the carrier to cargo delay claims under Part 370.

Part 375 text verified against the eCFR issue of 18 August 2026, read 21 August 2026 through the eCFR; the section links point at the current text, so where the two differ, the live page wins. Nothing here is legal advice — no licence to move, broker, advise or adjust, and no fee from any carrier. What is here is the section number printed beside the rule.
