Understanding the Merchandise Processing Fee (MPF) in 2026: Rates, Exemptions, and Importer Strategies

Imagine your shipment arriving smoothly at a U.S. port after weeks of careful planning, only to face an unexpected bill that chips away at your profit margins. As logistics professionals at FreightAmigo Services Limited, we see this scenario play out too often with the Merchandise Processing Fee—or MPF fee—a mandatory charge from U.S. Customs and Border Protection (CBP) that catches many importers off guard. This fee, often confused with duties, can add up quickly if not anticipated, turning a cost-effective import into a financial headache. In this comprehensive guide, we break down everything you need to know about the merchandise processing fee in 2026, empowering you to navigate it with confidence and precision.

What is the Merchandise Processing Fee (MPF)?

The merchandise processing fee, commonly referred to as the MPF fee or MPF charges, is a user fee imposed by CBP to cover the costs of processing import entries into the United States. Established under 19 U.S.C. § 58c and detailed in 19 CFR 24.23, it applies to most formal and informal entries of goods, regardless of value or origin—unless specifically exempt. Unlike import duties or tariffs, which are taxes on the value or quantity of goods, MPF is purely a processing charge calculated ad valorem (as a percentage of the shipment's appraised value under 19 U.S.C. § 1401a, typically the transaction value excluding freight, insurance, and duties).

Paid by the importer of record at the time of entry summary filing via the Automated Commercial Environment (ACE) system, MPF ensures CBP can maintain efficient border operations. We at FreightAmigo have assisted countless clients in demystifying this fee, preventing underpayments that could lead to retroactive billing and penalties. Note that 'MPF duty' is a common misnomer—MPF is not a duty but a distinct fee, and clarifying this distinction is crucial for accurate budgeting.

For international businesses shipping to the U.S., especially from hubs like Hong Kong, MPF represents a predictable yet often overlooked cost in the total landed price. Overlooking it can inflate your effective freight rates by 0.3% or more on larger shipments, eroding competitiveness in tight markets.

Current MPF Rates for FY2026

FY2026 rates, effective from October 1, 2025, reflect a 2.67% inflation adjustment based on the Consumer Price Index for All Urban Consumers (CPI-U), as mandated by the FAST Act and 19 CFR 24.22(k). The ad valorem rate remains steady at 0.3464% since 2011, but minimums and maximums have increased, alongside flat fees for informal entries.

For express consignment or centralized hub facilities, the fee is approximately $1.34 per air waybill or bill of lading, with a minimum of $0.35 and quarterly payments. These rates apply to shipments processed through ACE, and aggregated entries (e.g., multiple invoices) are treated as a single entry for fee calculation, which can help minimize costs on consolidated loads.

In our experience supporting clients with sea freight and air freight to the U.S., formal entries dominate for commercial volumes over $2,500, where the ad valorem structure scales with value. For instance, a $50,000 shipment incurs about $173.20 in MPF (before caps), a figure we help clients forecast precisely.

How to Calculate MPF Charges

Calculating MPF is straightforward for formal entries: multiply the appraised value by 0.3464%, then apply the minimum ($33.58) if below threshold or cap at $651.50 if exceeding. The threshold for minimum is roughly $9,694 (33.58 / 0.003464), and maximum kicks in above $188,077. Informal entries use flat fees based on processing method—automated is cheapest at $2.69 for values ≤$2,500.

Appraised value excludes inland freight, insurance, and duties, focusing on the customs value at import. For mixed entries, prorate exemptions. CBP publishes tools and guidance, but real-world variables like entry type and exemptions require expertise. That's where our Duties & Taxes Calculator shines, providing instant estimates of MPF alongside duties and taxes for U.S. imports, helping you budget accurately from day one.

This interactive tool integrates seamlessly with our platform, factoring in current MPF rates for routes like Hong Kong to the U.S., ensuring no hidden costs surprise your operations.

Key Exemptions from MPF

Not all shipments incur MPF. Exemptions under 19 CFR 24.23(c) cover a wide range, from de minimis (≤$800) to U.S.-origin goods and specific programs. Ad valorem MPF is waived for HTSUS Chapters 98/99 (e.g., U.S. returns, personal effects), insular possessions, and beneficiaries under CBI or least-developed programs.

FTA-qualifying goods enjoy full or partial exemptions if documented properly. Unconditionally free goods under preferences are also exempt, even without 'Free' in the HTSUS Special column. For mixed entries, prorate the fee to the non-exempt portion. Our Customs Clearance service leverages AI-driven HS code validation and compliance checks to identify these exemptions automatically, saving clients thousands annually on MPF charges alone.

Non-EMS mail, §1321(a)(2) releases, and U.S. ag products in FTZs (fee only on containers) further reduce exposure. We guide clients through documentation to maximize these benefits, particularly for eCommerce and relocation shipments.

Recent Updates and Compliance Considerations

The July 23, 2025, Federal Register notice (90 FR 34665, CSMS #65741993) confirmed FY2026 adjustments, with no ad valorem change. CBP's User Fee Table, updated January 22, 2026, remains the authoritative source. As of April 2026, no further tweaks are announced, but annual CPI reviews continue.

Compliance is key: Underpayments trigger audits and interest. Use ACE for filings, aggregate entries wisely, and verify exemptions via certificates of origin. For Turkish importers querying 'MPF nedir' (what is MPF?), it's this U.S.-specific fee—critical for any exporter targeting America. We support global clients, including those from Asia, with proactive strategies to stay ahead of CBP changes.

Challenges include misclassification leading to higher fees or penalties. Our platform's real-time tracking and PO-to-POD tools complement customs prep, ensuring seamless U.S. entry.
