**TRE Dictionary**

## Accessorial Service

An **accessorial service** is a service beyond the basic transportation or core move that is required or requested because of the shipment, property, or customer needs.

### In plain English

Examples can include packing, unpacking, stairs, shuttle service, long carries, crating, storage, appliance servicing, and other additional work.

### Why it matters

Accessorial services can change labor, equipment, time, and charges, so they should be identified and authorized clearly. FMCSA requires covered interstate estimates to include known accessorial and advance charges when the estimate is prepared.

### TRE common-language definition

> **Accessorial Service:** An additional moving service required beyond the base transportation or labor scope.

### Check the service and the charge separately

An accessorial service may already be included in the agreed price. Ask for the [tariff](https://relocationecosystem.com/tariff/) item or applicable service terms, what triggers the charge, included allowances, units, minimums and discounts. Match these to the [estimate](https://relocationecosystem.com/estimate/) and the actual work; the service name alone does not establish an extra fee.

For covered interstate moves, [49 CFR 375.401(f)](https://www.ecfr.gov/current/title-49/section-375.401?ref=relocationecosystem.com) requires accessorial charges such as elevators and long carries to be determined before the bill of lading. A later addition needs the appropriate [change record](https://relocationecosystem.com/change-of-scope/). Who requested it and when matters: mover-identified necessary services and customer-requested additions after the bill of lading have different notice and collection rules under [375.403(a)(8)–(9)](https://www.ecfr.gov/current/title-49/section-375.403?ref=relocationecosystem.com) and [375.405(b)(9)–(10)](https://www.ecfr.gov/current/title-49/section-375.405?ref=relocationecosystem.com). Use the [Unexpected Moving Costs guide](https://relocationecosystem.com/unexpected-moving-costs-guide/) to distinguish the final bill from the amount collectible at delivery. Other jurisdictions and service models may follow different rules.
