Detention and demurrage

Shipping containers belong to the shipping lines. After a container is discharged (unloaded) from a ship, it starts accruing demurrage charges.

DIM factor

The DIM factor is the number that a shipping company uses to calculate dimensional weight charges. The higher the DIM factor, the lower the dimensional weight charges. See dimensional weight for a full explanation of this pricing method for oversized packages.

Dimensional weight/DIM weight

The resulting number is the DIM weight and packages are charged the greater of dimensional or actual weight. DIM Weight = Length x Width x Height then dividing by a DIM factor.

A distribution center is a warehouse that’s used as a waystation for transferring goods from one mode of transport to another.

Long-term storage in a fulfillment warehouse refers to inventory held in the warehouse for more than six months or more than 12 months. Long term storage may incur extra storage fees, so savvy inventory management should ensure that stock turns over at least once every six months or year.
