FDA Customs Holds on Medical Devices

Import Enforcement

Why FDA Detains Imported Medical Devices

FDA detains imported medical devices under Section 801(a) of the FD&C Act when they appear to be adulterated, misbranded, or in violation of the pre-market notification (510(k)) or approval requirements. The most common triggers for medical device detention are: the device appears to require FDA clearance or approval and no clearance or approval record can be confirmed, the foreign manufacturer is not registered with FDA as required, the device label does not meet 21 CFR Part 801 requirements, the device is subject to an import alert that places it on automatic detention (Detention Without Physical Examination, or DWPE), or there are quality issues identified in prior FDA inspections of the manufacturer.

Import alerts are the most serious category of import enforcement. When a device or manufacturer is subject to an import alert, all incoming entries from that manufacturer are automatically detained without physical examination — meaning FDA will detain every shipment until the import alert is lifted. Getting off an import alert requires submitting evidence to FDA that the conditions that prompted the alert have been corrected, and that the specific shipment being detained satisfies the applicable requirements.

Responding to FDA Import Detention Notices

When FDA issues a notice of detention and hearing, the importer or owner has a limited window to present testimony and evidence to FDA explaining why the shipment should be admitted. The response strategy depends on the detention reason: for apparent 510(k) violations, the response should demonstrate clearance status or provide a basis for 510(k) exemption. For labeling issues, the response must demonstrate how the labeling will be brought into compliance. For quality-based detentions or import alert coverage, the response must address the underlying compliance concern with documented corrective actions.

A detention response that doesn't address FDA's stated basis for detention, or that makes claims without documentation, will result in refusal of admission. A refused shipment must be either re-exported or destroyed. We prepare detention responses that directly address the regulatory basis for detention with supporting evidence, and we coordinate with FDA district offices where clarification or supplemental submissions are needed to facilitate release.

Reconditioning and Admission Conditions

In some cases, FDA will permit a detained shipment to be admitted conditionally — subject to reconditioning that brings the product into compliance before distribution. Reconditioning may involve relabeling, additional testing, or other corrective actions depending on the nature of the violation. The reconditioning process requires FDA oversight and documentation of the corrective actions taken. We prepare reconditioning proposals and supervise reconditioning programs to ensure the process satisfies FDA's requirements for conditional admission.
