What is Merchandise Processing Fee?
The Merchandise Processing Fee (MPF) is a payment that needs to be made to the US Customs and Border Protection (CBP) for imports into the US. MPF is considered to be an ad valorem tax, meaning that it is a percentage of the estimated value of the imported goods. This fee is levied for imports made formally or informally.
The value of MPF is based on the assessed value of the imported goods, and it is calculated as proportionate to the estimated value of goods. MPF can be considered to be a tax that is paid in addition to the duties levied on any given shipment's entry summary.
How is Merchandise Processing Fee Calculated?

The value of MPF is 0.3464% of the cargo value that was declared on the commercial invoice for imports. This fee is based on the value of the imported merchandise, excluding freight expenses, insurance charges, and duty.
The MPF charge is fully covered by the importer of the goods. MPF for informal entries is assessed on goods transported to the US via air, ship, and international mail and is a fixed fee that ranges from US$2, US$6, and US$9 for every shipment.
Formal entries are required for the import of goods valued at US$2,500 or higher. On the other hand, informal entries are for imports involving personal use or for commercial imports valued under US$2,500 (On the basis of importation requests made by the port director).
