How HMM counts free time

HMM publishes its basic US free time and tariff in a search on its DEM/DET Tariff (Basic) page , by location, container type and demurrage or detention. The filed rules it cites are HDMU-040 Rules 101 and 101-1 for demurrage at destination and HDMU-038 Rule 21-2 for detention. What the page and Rule 21-2 say about counting:

A service contract can give different free time.

Before you pay

Compare the invoice with the tariff and with the contract. If the free time or the daily rate does not match, or the invoice leaves out what the FMC requires, see what a US invoice must show and how to dispute it . Other tools: last free day, any carrier .
