MPF Exceptions, Refunds, and Disputes: Managing the Merchandise Processing Fee

Merchandise Processing Fee (MPF) A U.S. customs user fee assessed on many formal import entries, subject to applicable rules and exceptions. While MPF is routine, importers frequently encounter exemptions, refund opportunities, and disputes that require administrative action with CBP.

Knowing the common exceptions and the process for seeking refunds or disputing MPF assessments is essential for importers, customs brokers, and warehouse operators. Mistakes in entry classification, valuation, or entry type can inflate MPF charges; likewise, legitimate exemptions or corrections can recover previously paid fees if handled correctly.

Common MPF Exceptions

Certain imports are exempt from MPF by statute or regulation. Typical exemptions include informal entries under the de minimis threshold, certain government or diplomatic imports, some temporary imports under bond, and some returned U.S. goods. Exemption eligibility often depends on accurate claim codes and supporting documentation at the time of entry.

• Informal Entries: Low‑value shipments below the de minimis threshold generally avoid MPF.
• Returned Goods: Goods returning to the U.S. under qualifying conditions may be exempt.
• Government/Diplomatic Shipments: Specific governmental imports have statutory exemptions.

When Refunds Are Available

Refunds are possible when an entry is corrected or liquidated at a lower value, when an exemption was applicable but not claimed, or when CBP determines an entry was improperly charged. Refund requests require documentation and formal procedures — often filed via a broker or customs attorney — and must meet CBP timelines and evidence standards.

How To File A Protest Or Request An MPF Refund

If an importer disagrees with liquidation or MPF assessment, they may file a protest with CBP within regulatory timeframes. A protest challenges the legal or factual basis of the assessment (including classification or valuation). For refunds that do not require a protest (for example, administrative errors), importers work with CBP’s post‑liquidation procedures to request an adjustment or refund.

• Label: Protest Filing: Use the formal protest process for legal/valuation disputes; include evidence and follow CBP timelines.
• Label: Administrative Refunds: For clerical or entry type errors, submit requests with supporting docs to CBP’s designated teams.
• Label: Broker Assistance: Customs brokers commonly prepare and submit protests and refund requests on behalf of clients.

Common Dispute Triggers

Disputes often arise from incorrect declared values, wrong HTS codes, mistaken entry types, or failure to claim a valid exemption. Timely internal audits of entry records help detect issues early. For multi‑party supply chains, clear records about the importer of record and transaction terms reduce disputes about who is entitled to a refund or who is liable for MPF.

Practical Steps For Managing MPF Risk

• Label: Audit entries monthly in ACE to find mischarges; reconcile broker invoices to ACE entries.
• Label: Maintain complete documentation for valuations and exemptions — invoices, contracts, shipping docs, and proof of return shipments.
• Label: Train internal teams and brokers on entry selection: choosing formal vs. informal entries correctly matters for MPF exposure.
• Label: When in doubt, consult customs counsel or a licensed broker before filing protests; procedural errors can forfeit refund rights.

Case Example: Recovering MPF After Valuation Change

A retailer is assessed MPF on an imported shipment. After a post‑entry reconciliation, the declared value is reduced due to an invoicing correction. The importer files for a refund with CBP, supplying corrected invoices, entry summaries, and the broker’s payment records. CBP reviews the documentation and issues a refund under its administrative procedures once the claim is validated.

In short, the Merchandise Processing Fee (MPF) can be managed proactively: understand exceptions, keep accurate records, reconcile ACE entries, and use formal protest or refund channels when appropriate. These practices minimize unnecessary MPF costs and ensure proper recovery when errors occur.
