What is the Merchandise Processing Fee (MPF)?

Tariffs and customs glossary · 2 primary sources

A CBP user fee of 0.3464% of the customs value on formal entries, with a minimum and maximum per entry that CBP adjusts each fiscal year.

MPF is charged in addition to duty on most formal entries. Because of the yearly minimum and maximum, small entries pay the minimum and very large entries pay the cap. Goods qualifying under some trade agreements, such as USMCA, are exempt.

Ocean shipments also pay the Harbor Maintenance Fee, 0.125% of the value of commercial cargo loaded or unloaded at US ports (19 CFR 24.24).

Example: A $40,000 formal entry: $40,000 × 0.3464% = $138.56 MPF (then checked against that year's minimum and maximum).
