FDA Detained Your Supplement Shipment for Missing FSVP? How a $10,000 Amazon FBA Shipment Was Released in 2 Weeks (2026)

Last Updated: October 2026
In January 2024, FDA detained a Vietnamese supplement brand’s first Amazon FBA shipment, worth $10,000 in invoice value, because no FSVP importer had been named for it. We stepped in as FSVP agent, verified the manufacturer in 2 working weeks, and FDA released the shipment about 2 weeks after the client first contacted us; it went on to Amazon FBA and sold.
This case study explains what an FDA detention for missing FSVP means, what we checked to clear it, and what to set up before your own first shipment so it never sits at the port.
| Client type and origin | Dietary supplement brand from Vietnam, selling on Amazon US through FBA |
| Product | Dietary supplement pills, first trial shipment |
| Problem | FDA detained the shipment in January 2024 because no FSVP importer had been named. The client did not know about the FSVP rule. |
| What GOL did | Urgent FSVP agent service: verification of the manufacturer (GMP certificates, COAs, production process and a hazard review), then a Letter of Consent confirming we act as FSVP agent for the shipment. |
| Timeline | Verification completed in 2 working weeks. Shipment released about 2 weeks after the client contacted us. |
| Loss avoided | $10,000 invoice value protected. The shipment reached Amazon FBA and sold, instead of building up storage fees and losing shelf life at the port. |
What happened to the shipment?
FDA detained the shipment at the US port because nobody had been named as its FSVP importer. It was the brand’s first trial shipment of supplement pills, bound for Amazon FBA.
The client was getting ready to sell on Amazon, but did not know about the Foreign Supplier Verification Program (FSVP), so the shipment arrived with no FSVP importer behind it.
Why does FDA hold a shipment when no FSVP importer is named?
Every food entry, including dietary supplements, must name an FSVP importer when the entry is filed with US Customs and Border Protection: its name, email address and an FDA-recognized unique facility identifier, for each line entry (21 CFR 1.509). FDA recognizes the DUNS number as that identifier (FDA FSVP at a glance).
The FSVP importer is the US owner or consignee of the food at entry. If there is none, it is the US agent or representative of the foreign owner or consignee, “as confirmed in a signed statement of consent to serve as the importer” (21 CFR 1.500). A brand with no US owner or consignee at entry therefore needs someone in the US to sign that consent.
Selling through Amazon does not change this. Amazon’s food and beverages policy requires products to “comply with all applicable import requirements”, and its dietary supplements policy requires compliance with FDA rules, but neither names an FSVP importer for you.
For finished dietary supplements, the FSVP rule generally expects the importer to approve the foreign supplier and verify it before importing, through onsite audits, sampling and testing, a review of the supplier’s food safety records, or other suitable checks (21 CFR 1.511(c)).
What was at risk while the shipment waited at the port?
The whole $10,000 shipment was at risk, plus the time it was losing. A detained shipment is given time to supply the missing documents, but three costs grow while it waits.
- Storage fees at the port build up for every day the cargo sits there.
- Shelf life runs down. Supplements carry expiration dates, and every week at the port is a week less to sell them.
- The launch stalls. A first trial shipment is meant to test the market. Every week at the port is a week with no sales data.
If the documents had taken much longer, the products might no longer have been sellable at all.
What did GOL do to get the shipment released in 2 weeks?
We became the FSVP agent for the shipment, which meant verifying the manufacturer first and then signing our consent to serve as FSVP importer. We did both within 2 working weeks.
Step 1: Verify the manufacturer
Under the strict timeline, we reviewed the Vietnamese manufacturer’s:
- GMP certificates
- Certificates of analysis (COAs) for the product
- Production process
- Hazards for the product, in a hazard review
The request list is a case by case list based on the product type, its risk profile and company profile.
Step 2: Issue the Letter of Consent
Once the verification was complete, we issued our Letter of Consent, which confirms that we agree to act as FSVP agent for the shipment. This is the signed statement of consent that 21 CFR 1.500 describes.
Step 3: Release and on to Amazon FBA
With an FSVP importer in place, FDA released the shipment about 2 weeks after the client first contacted us. The shipment went on to Amazon FBA and sold.
Client Experience
The brand came to us after FDA had already detained its first Amazon shipment. They had not known that an FSVP importer was needed, so no one had been named.
We ran the verification on an urgent timeline, covering GMP certificates, COAs, the production process and a hazard review, and completed it within 2 working weeks. We then issued our Letter of Consent and became the FSVP agent for the shipment.
FDA released the shipment about 2 weeks after the client contacted us. It reached Amazon FBA and sold. The matter is fully closed, and the brand is still our client.
How did the 2 weeks unfold?
| When | What happened |
|---|---|
| January 2024 | The first trial shipment of supplement pills arrives in the US. FDA detains it because no FSVP importer has been named. |
| Day 0 | The client contacts GOL. |
| Within 2 working weeks | GOL verifies the manufacturer (GMP certificates, COAs, production process, hazard review) and issues its Letter of Consent as FSVP agent for the shipment. |
| About 2 weeks after Day 0 | FDA releases the shipment. |
| After release | The shipment moves to Amazon FBA and sells. |
| Today | Matter fully closed. The brand remains a GOL client. |
What should you set up before your first shipment?
Name your FSVP importer and finish the supplier verification before the goods leave the factory, because the requirement applies to every food entry, including a small trial shipment.
- Decide who the FSVP importer is. If no US owner or consignee will receive the goods at entry, line up a US agent or representative who will sign the consent.
- Give the FSVP importer’s details to the US broker who files the entry: name, email address and DUNS number.
- Prepare the manufacturer’s documents: GMP certificates, COAs, a description of the production process and the information needed for a hazard review.
- Keep the other FDA filings separate in your plan. FSVP does not replace food facility registration or Prior Notice for each shipment.
GOL Insight
A $10,000 trial order is easy to treat as too small for a compliance program. The rule does not scale with order size: each food entry must name an FSVP importer.
Doing the verification after a detention is possible, as this case shows, but it is done against the clock, with storage fees and expiry dates running. Doing it before shipping costs the same verification work without the port risk.
When does this not apply?
This fix works for a detention caused by a missing FSVP importer. It does not fit every hold.
- FDA held the shipment for a different reason, such as labeling, contamination or a missing facility registration. Naming an FSVP agent will not fix those on its own.
- A US owner or consignee already receives the goods at entry. That company is the FSVP importer and must run the program itself, or hand the work to a provider while keeping the responsibility.
- The manufacturer cannot supply verification documents. Without GMP certificates, COAs and process information, no FSVP agent can verify the supplier, and the timeline in this case would not be possible.
Frequently asked questions
Can a foreign brand be its own FSVP importer?
The FSVP importer is the US owner or consignee of the food at entry. If there is none, it is a US agent or representative of the foreign owner or consignee who signs a statement of consent. A brand with no US owner or consignee at entry needs someone in the US to take that role.
Does selling through Amazon FBA change who the FSVP importer is?
No. Amazon’s food and supplement policies require compliance with import and FDA rules, but they do not name an FSVP importer for you. FDA’s definition in 21 CFR 1.500 decides who it is.
What documents does an FSVP agent need from the manufacturer?
In this case we reviewed GMP certificates, COAs, the production process and a hazard review. For dietary supplements, the FSVP rule expects the importer to approve the supplier and verify it through audits, testing, record review or other suitable checks.
How long does it take to clear an FDA detention for missing FSVP?
In this case, about 2 weeks from the client contacting us to release, with the verification itself completed in 2 working weeks. It depends on how fast the manufacturer can supply its documents.
What does FSVP agent service cost?
It varies case by case, depending on the product, the supplier and whether you need it for one shipment or a full year. Send us your details and we will quote your exact cost.
What should you send GOL if your shipment is detained?
Send us the items below on the day you receive the notice, and we will tell you whether we can act as your FSVP agent, how long verification will take, and your exact cost. You can also start from our FSVP service page.
- The FDA notice for the shipment, the entry number and the arrival date.
- Your product list and the manufacturer’s name and address.
- The manufacturer’s GMP certificates and COAs.
- A description of the production process, and any hazard analysis the manufacturer already has.
- The commercial invoice and the bill of lading or air waybill.
