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 ($34.58 minimum and $670.86 maximum per formal entry from 1 October 2026, FY2027, CBP Dec. 26-14, 91 FR 48398; FY2026 was $33.58 to $651.50). 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.

Frequently asked questions
What is Merchandise Processing Fee (MPF)?
MPF is a 0.3464% duty-like fee levied on the dutiable value of all imports into the US, with a minimum of $34 and maximum of $510 per entry. It funds CBP operations and is separate from tariff duties. MPF applies to almost all imports unless specifically exempted.
What is Harbor Maintenance Fee (HMF)?
HMF is a 0.125% fee on cargo imported by sea (commercial invoiced value, CIF). It funds harbor maintenance and dredging. Only sea-imported cargo is subject to HMF; air, rail, and overland imports are exempt. HMF has no minimum or maximum cap.
Are there exemptions from MPF?
Yes. Goods from most free-trade agreement partners (NAFTA, KORUS, etc.) are exempt. Some categories (humanitarian aid, certain chemicals, metals) are also exempt. The August 2025 de minimis import exemption suspension means all entries, even low-value, now incur fees.
