Extra Items on a Binding Estimate: What the Mover Signs Before Loading

When the crew finds goods a binding estimate never listed, the federal rule for interstate moves gives the mover three choices, and each one has to happen before loading: reaffirm the binding estimate, prepare a new binding estimate that the shipper signs, or agree with the shipper in writing to treat the original as non-binding. Load the truck without any of them and the original binding estimate is reaffirmed — the extra goods ride at the price already signed. Pages about binding estimates speak to the customer; this one is for the mover’s office and crew lead. It covers what 49 CFR 375.403 says, what changes after the bill of lading is issued, two state rules for moves within one state, a before-loading routine, a count to run on the last 20 interstate jobs, and when to hire no one. It is not legal advice: a transportation attorney can say how the rules apply to a specific move.

Answer it in the Self-Audit

The federal household-goods rules in 49 CFR Part 375 cover interstate moves for individual shippers: people who own the goods and pay their own charges. Under 375.401(b), a binding estimate is an agreement made in advance that fixes the total cost of the move based on the quantities and services it shows, and under 375.403(a)(4) its face must say that the charges apply only to the services it identifies. That clause is the opening for extra items, and the rule says exactly how to use it.

Section 375.403(a)(6) says that if the shipper has tendered additional goods or needs services the binding estimate did not identify, the mover is not required to honor the estimate, and if the two sides cannot agree on the price, the mover is not required to service the shipment. If the mover does service it, it must do one of three things before loading:

  • Reaffirm the binding estimate, and carry the extra goods at the signed price.
  • Prepare a new binding estimate before loading that lists the additional goods or services in detail, signed by the shipper. The rule adds that the mover should keep a record of the date, time and manner in which the new estimate was prepared.
  • Agree with the shipper, in writing, to treat the original binding estimate as a non-binding estimate under 375.405.

Then 375.403(a)(7): once the mover loads the shipment, failing to execute a new binding or non-binding estimate “signifies you have reaffirmed the original binding estimate,” and the mover may not collect more than the original amount, apart from the exceptions for services after the bill of lading. The general rule in 375.401(i) says the same in fewer words: an estimate may be amended before loading by mutual agreement, not after. The consumer booklet in Appendix A tells the shipper that the mover “may not change an estimate after loading the shipment.” Non-binding estimates follow a parallel rule with two choices instead of three — reaffirm, or prepare a new non-binding estimate the shipper signs (375.405(b)(7)) — and at delivery the mover may not require more than 110 percent of the non-binding estimate.

After the bill of lading: the one-hour rule and the 30-day bill

Some extras appear only after the bill of lading is issued — a shuttle at destination, a long carry nobody mentioned, a piece that will not fit the stairs. The rule splits those by who asks for them.

  • The mover believes added services are needed (375.403(a)(8)). The mover tells the shipper what they are before performing them and allows at least one hour for a decision. If the shipper agrees, a written attachment to the bill of lading is signed; it may travel by fax, e-mail, overnight courier or certified mail. The added services are billed after 30 days from delivery. If the shipper does not agree, the mover performs only what is required to complete delivery and bills that after 30 days, though impracticable-operations charges of up to 15 percent of all other charges due at delivery may be collected at delivery.
  • The shipper asks for added services (375.403(a)(9)). The mover states the added charges, the shipper agrees, and a new binding estimate is signed. The mover may then require full payment at destination for those services and for 100 percent of the original binding estimate, plus impracticable-operations charges up to the same 15 percent cap.

Two practical consequences follow. A crew that performs an extra without the one-hour notice and a signed attachment has turned a charge into an argument. And a charge the rule says is billed after 30 days from delivery is cash the office has to remember to invoice a month later — a separate hand-off with its own way of going missing.

Moves within one state: California and Florida

Intrastate moves follow state law, and two large states show how closely the logic tracks the federal rule. Other states differ; read the state’s own statute or tariff and take the question to an attorney who practices there.

  • California, Maximum Rate Tariff 4, Item 120. If the shipper asks for added services or adds articles not covered by the estimate or the Not to Exceed Price, the mover prepares a “Change Order for Services,” signed by the mover and the shipper before any of the specified service begins. It itemizes the added articles and services, the rates and the number of helpers and packers, carries a new not-to-exceed amount initialed by the shipper, and the mover keeps a copy for at least three years. Items 28 and 108 tie the maximum charge to the estimate or agreement plus charges on a change order completed under Item 120.
  • Florida, chapter 507. For moves that begin and end in Florida, section 507.05 requires a written estimate and contract, signed or electronically acknowledged and dated by the shipper and the mover, before any moving or accessorial services are provided, with an itemized breakdown of all costs and services. Section 507.11 makes it a third-degree felony to refuse a law enforcement order to release goods once the shipper has tendered the amount of the written estimate or contract and any signed amendments reflecting a price adjustment.

The common thread in all three: the price change is on paper, signed by the customer, before the work it covers.

What the driveway decision costs when nobody writes it down

Illustrative example: an interstate move booked on a binding estimate of $6,000 for a three-bedroom house. On loading day the crew lead opens a garage packed to the door and a shed the video survey never showed. The added goods take two extra hours to pack and load and fill more of the truck. The crew lead decides on the driveway, calls nobody, and the truck is loaded. Under 375.403(a)(7), loading without a new estimate reaffirms the original: the extra hours, the extra space and the extra materials ride at $6,000. If the added work would have priced at $900, that is $900 the company carried for a decision made in a minute. The numbers are hypothetical; the mechanism is not.

The opposite mistake costs too. A crew that loads first and adds a charge to the bill at delivery is charging against a rule that says the original estimate stands, and the customer who disputes it can point to the regulation. The money is gone either way; the second way adds a complaint.

The before-loading routine: crew lead, office, signature

The rule fits on one line: no extra goods go on the truck until the paper matches them. Four steps make it hold.

  • The crew lead walks the home against the estimate’s inventory before the first box moves, room by room, and photographs anything not on it — the garage, the shed, the second storage closet.
  • The office prepares a new binding estimate listing the added goods and services in detail, or a written agreement to treat the original as non-binding, and sends it for the shipper’s signature. A short price list for common additions, drawn from the company’s own tariff, lets the office price a garage or an appliance in minutes.
  • The shipper signs before loading. The office records the date, time and manner in which the new estimate was prepared, as 375.403(a)(6)(ii) says it should, and files it with the bill of lading.
  • If the shipper declines, the crew lead calls the office before anything loads. The company then decides — reaffirm the original on purpose, or decline to service the shipment as the rule permits — and writes down which.

Reaffirming is a legitimate choice: a few boxes may not be worth the conversation. The point is that it is a decision, made by someone with the authority to make it and written down, not the default that happens when the truck is loaded.

Count it on the last 20 interstate jobs

Before changing anything, measure the gap on finished moves. Take the last 20 interstate jobs on binding estimates and lay four records side by side: the signed estimate and any new estimate, the bill of lading and its attachments, the inventory, and the crew sheet with hours.

  • List every item or service on the inventory or crew sheet that the original estimate did not include.
  • For each, mark how it was handled: a new estimate or written conversion before loading, a signed attachment after the bill of lading, or nothing.
  • Note the crew hours and materials the extras took, at the company’s own rates.
  • Total the extras carried at the original price with no recorded decision, and the post-delivery charges that were due after 30 days but never invoiced.

Illustrative example: across 20 binding-estimate moves, the inventories show added goods on 7. Two have a new signed binding estimate, one a written conversion, and four have nothing. At an illustrative $700 of labor, space and materials each, the four unrecorded extras put about $2,800 of work inside prices already signed. The count also shows which crew leads call the office and which do not — the fix is a routine, not a reprimand.

When not to hire anyone for this

Skip outside help if every interstate job among the last 20 has an inventory that matches its estimate, or a signed change before loading where it does not. That company already runs the routine. Skip it if the company only does local moves within one state — read that state’s rule instead. And anything that has already become a dispute, an arbitration or a complaint belongs with a transportation attorney and the company’s own dispute program, not an operations review.

For a moving and storage company at about $1M a year and up, where estimators, crew leads and the office are different people and nobody can say how many extras went on trucks last season without a signature, the Revenue Review takes two weeks: read-only access to estimates, bills of lading, inventories, crew timesheets and the books, ending in a written report that puts a monthly dollar figure on each leak the records support. It is not a compliance audit and gives no legal advice, and we do not run a moving company. Implementation is scoped and priced separately. A free 20-minute call is enough to tell whether it fits, including when it does not.

Asked right after

Can a mover charge more than a binding estimate?
On an interstate move, only within the rule. Before loading, the mover and shipper can sign a new binding estimate or convert the original to non-binding in writing. Loading without either reaffirms the original. After the bill of lading, added services need notice and a signed attachment and are billed after 30 days from delivery, and impracticable-operations charges at delivery are capped at 15 percent of other charges due. A transportation attorney can speak to a specific move.
What happens if the customer adds items on moving day?
Under 49 CFR 375.403(a)(6), the mover need not honor the binding estimate for goods it did not identify, and need not service the shipment if no price is agreed. If it does service the shipment, before loading it must reaffirm the estimate, prepare a new signed binding estimate listing the additions, or agree in writing to treat the original as non-binding.
Can a binding estimate be changed after the truck is loaded?
Not under the federal rule for interstate moves. Section 375.401(i) allows an amendment before loading by mutual agreement and says the estimate may not be amended after loading, and 375.403(a)(7) treats loading without a new estimate as reaffirming the original. Services found necessary after the bill of lading follow a separate notice-and-attachment rule.
Do binding estimate rules apply to local moves?
The federal rules in 49 CFR Part 375 cover interstate moves for individual shippers, not moves within one state. Intrastate moves follow state law: in California, a Change Order for Services signed before the added service begins under Maximum Rate Tariff 4, Item 120; in Florida, a signed estimate and contract before any service under section 507.05. Other states differ.
Can a moving company charge for a binding estimate?
Under 49 CFR 375.401(b), a mover may charge for providing a written binding estimate on an interstate move, and may not charge for a non-binding estimate. Under 375.403(a), a binding estimate must also be provided for in the mover’s tariff.
