Overview & methodology
Understanding MPF and HMF Caps
The Merchandise Processing Fee (MPF) is calculated as 0.3464% ad valorem for formal entries, but it is subject to strict minimum and maximum caps (e.g., ~$32 to ~$635 per entry). The Harbor Maintenance Fee (HMF) is 0.125% of the cargo value with no maximum cap. The Section 321 de minimis exemption for shipments of $800 or less has been suspended for goods from all countries since 29 August 2025, so low-value commercial shipments now need an entry and pay the applicable duties; check current CBP guidance for the entry type and fees.

These fees are additive to any basic customs duty (MFN) or trade enforcement duties (Section 301/232) that may apply to the shipment.
