The practical answer
A Notice of FDA Action can mean FDA is examining or sampling a shipment, has detained it, or has refused it. Detained products may be defended with testimony and records, generally within 10 business days under FDA's procedures (the notice usually allows 20 calendar days). A refusal is final: the product must be exported or destroyed under supervision within 90 days, and FDA cannot extend that period. [3] [4] [5]
Evidence, method & source dates ↓Who this is for
Laboratories sometimes learn that an imported peptide order is "on FDA hold" from a supplier or courier. This guide explains, from FDA's own pages, what each stage means, what records can be provided and where refusal data is published. It is a records guide. It does not offer ways to avoid review, and it does not predict the outcome for any product.
FDA states that refused products may be those that appear adulterated, misbranded, or forbidden or restricted for sale, and that products must be held and may not be distributed until FDA decides admissibility. [1]
The stages in order
U.S. Customs and Border Protection refers FDA-regulated entries to FDA. FDA's electronic screening uses various sources of information to assess risk, such as a firm's previous compliance history, and entry submissions with incomplete or inaccurate information are flagged for manual review. [2] From there an entry can move through the stages below.
| Stage | What FDA says it means | What to record |
|---|---|---|
| Release | Product may enter commerce; release does not preclude later action [3] | Date and entry number |
| Documents required | FDA requests labels, certificates, ingredient lists, processing records or analytical information [3] | What was requested, what was sent, when |
| Examination or sampling | Physical inspection, label review, or lab sample; goods must be held [6] | Notice date and lines affected |
| Detention | Notice lists apparent violations (charges); owner or consignee may respond [4] | Each charge verbatim; response deadline |
| Reconditioning request | Importer of record may apply on Form FDA 766 to relabel or recondition [7] | Plan submitted and FDA decision |
| Refusal | Final decision; export or destroy within 90 days under supervision [5] | Refusal date and disposition evidence |
Detention: the window to respond
FDA issues a Notice of FDA Action marked "Detained," which serves as the notice of detention and hearing and lists the charges. FDA says its Regulatory Procedures Manual allows 10 business days from the date of detention, and that the notice generally allows 20 calendar days. The owner or consignee may submit oral or written testimony, including entry documentation; The owner, consignee or importer of record may respond; anyone else needs written authorization. Extensions can be requested within the timeframe with a reasonable basis. [4]
FDA notes that ITACS is its preferred channel for documents, that products under detention without physical examination may be sampled and tested by a private laboratory as evidence, and that if no response arrives in time the compliance officer can refuse admission. [4] If you are not the importer of record, your role is usually to give the importer accurate documents quickly.
Records a laboratory buyer can supply
FDA's entry review page lists product labels, certificates, ingredient lists, processing records and analytical information as typical entry documents. [3] For a research peptide order, the useful set is the purchase order and invoice showing the buyer, the product labels as shipped, the lot-specific certificate of analysis, any safety data sheet, and a short statement of the material's laboratory purpose that matches how it was actually ordered and labeled.
Accuracy matters more than volume. Documents that contradict the labels or the supplier's marketing create new questions. Do not move or use goods while they are held; FDA says it may ask CBP to order the return of held goods that are distributed without permission. [6]
Refusal and administrative destruction
FDA defines a refusal as its final decision that a detained shipment violates FDA laws and regulations, and says it generally will not rescind one unless issued in error. The shipment must be destroyed or exported under CBP and FDA supervision within 90 days of the notice; FDA cannot grant extensions, and CBP may assess liquidated damages against the bond if the deadline is missed. [5]
Separately, FDA implemented administrative destruction authority for drugs on April 4, 2016. It covers refused drugs valued at $2,500 or less offered for import through international mail and express couriers, after a Notice of FDA Action giving the owner an opportunity to appear and introduce testimony. [8] A small research order sent by mail or courier can therefore be destroyed rather than exported.
Searching refusal data before you order
FDA's Data Dashboard publishes import refusals for shipments refused on or after 10/01/2016, filterable by product category including Drugs and Biologics, by country of origin and fiscal year, with a downloadable reference list of refusal charges. FDA says the datasets are updated weekly, include only final actions, and may not reflect later changes. [9] Older records are in the Import Refusal Report. [5]
Use it as background, not a verdict: a refusal record shows a final action on a shipment, not a finding about every product from that origin. Record the search date, filters and what you found, in the same way as a warning-letter search.
A fictional notice
An invented lab is told its supplier's shipment is detained. The importer of record forwards the notice: one line, charge "appears to be a new drug without an approved application." The lab record reads: "Notice dated 3 March, detained; response window per notice 20 calendar days. Lab supplied PO, invoice, lot certificate and SDS to importer on 5 March. Outcome pending." The lab does not reorder the same material through a different route while the matter is open.
Questions before you decide
Can the 90-day export or destruction deadline be extended?
FDA says it cannot grant extensions after a refusal; questions about the period go to the local CBP office.
Does a release mean FDA has approved the product?
No. Release means the product can be distributed in the US, and FDA says a release does not preclude future action if a problem is found later. Admission at the border is not a drug approval.
