A tariff is a document that must be published by every interstate household goods moving company.
Among other things, the tariff lists the prices, rules, policies, and types of services offered by the mover.

Penalties for violating tariff rules and regulations can be both civil and criminal in nature. An interstate moving company may lose its operating authority. Any moving company that charges rates that are not consistent with their published tariff shall be liable for a civil penalty of up to $100,000.00 per violation. In addition, criminal charges for charging rates not consistent with the tariff may include a fine and prison for up to two (2) years for each violation.

This site offers tariff publishing for moving companies. Alternatively, movers may create or have a competent professional create a tariff for them, so long as the tariff meets all legal requirements.

Beginning on January 1, 2008, the Surface Transportation Board (STB) ruled that moving companies are not immune from collective ratemaking. Continuing to use generic tariffs such as the 400N may therefore subject moving companies to anti-trust violations. By creating its own tariff, moving companies are able to create custom services and rates that apply to its business model.
