I Received an FDA Notice of Action. Now What?
Companies often learn their shipment has been flagged for detention without physical examination (DWPE) through an FDA Notice of Action (NOA). This notice provides critical details required to initiate the process of securing your product’s release, including…
How the shipment appears to be in violation
Notification of your right to hire a third-party lab to provide evidence that your products are not violative
The number of days you have to provide testimony to the FDA (typically 20 calendar days)
The contact information for the Consumer Safety Officer (CSO) with whom you should work to resolve the issue
Get Your Products Released From FDA Import Detention (DWPE) Now

The FDA can detain your products if they appear to be…
-
- Adulterated or contaminated
- Misbranded
- Forbidden or restricted for sale
Whatever the case, detained shipments waste time, harm your reputation, and cost money each day your products are sitting in a warehouse rather than in commerce. It’s important to act quickly and partner with a laboratory and consultants who can help get your products released from FDA detention as soon as possible.
Respond to the Notice of Action Immediately
If you receive a Notice of Action, read it immediately. Understand the “charges”, which are the reasons the shipment is detained. Find the “respond by” date so you can make a plan.
The FDA allows you to provide evidence to overcome the charges or request to recondition the product to resolve the issue.
DWPE – We Can Help Get Your Products Released Quickly
The FDA import process can quickly become confusing and even intimidating. The submission of evidence to the FDA must contain certain information, otherwise it can be rejected. If that happens, you may have to export or destroy the products, wasting time and money.
Contact us today so we can help ensure that doesn’t happen.
