Import Alerts: How the FDA Blocks Drugs from Non-Compliant Manufacturers

What Are FDA Import Alerts and Why Do They Matter?

Every day, millions of drug shipments cross into the United States. But not all of them are safe. The FDA doesn’t inspect every single package-that’s impossible. Instead, it uses something called Import Alerts to stop bad drugs before they even reach pharmacy shelves. These aren’t random checks. They’re automated blocks based on history. If a manufacturer has been caught cutting corners before, the FDA flags them. Future shipments? Automatically detained. No inspection needed.

This system, powered by the FDA’s PREDICT algorithm, tracks over 150 data points: past inspection failures, refusal rates, facility conditions, even the quality of paperwork. Since September 2025, the most aggressive use of this tool has been against GLP-1 weight-loss drug ingredients like semaglutide and tirzepatide. The agency issued Import Alert 66-80 to target these APIs after finding widespread contamination, incorrect dosing, and fake certificates of analysis.

The Green, Yellow, and Red List System

The FDA doesn’t just say ‘block everything.’ It uses a color-coded system to show where a manufacturer stands:

• Green List: Manufacturers with proven compliance. Their shipments clear customs within hours. Around 99.2% of Green List shipments are released without delay.
• Yellow List: Manufacturers under watch. Shipments are held for review. They can still get in-but only if they prove they’ve fixed the issues.
• Red List: Repeated violators. Shipments are automatically detained and held at the port. No exceptions. Nearly 98.7% of shipments from non-Green List GLP-1 API makers were refused in October 2025.

There’s no gray area. If you’re not on the Green List, your product is at risk. And getting on it isn’t easy. It takes a full facility audit by an FDA-recognized third party, stability testing under three different temperature conditions, and proof your supply chain goes all the way back to raw material sources.

How a Shipment Gets Blocked-And What Happens After

Here’s how it works in practice. A shipment of semaglutide API arrives at the Port of Los Angeles. The FDA’s system instantly checks the manufacturer’s name against its database. If the facility isn’t on the Green List, the system triggers a detention without physical examination (DWPE). The shipment sits at the port. The importer gets a notice: “Provide corrective action plan within 5 days.”

What does that mean? They need to submit:

• A Certificate of Analysis (CoA) that meets FDA formatting rules
• Third-party audit reports from FDA-approved auditors
• Full facility master production records
• Traceability of every raw material to Tier 3 suppliers

Most companies fail. One manufacturer on Reddit reported losing $1.2 million in 72 hours because their auditor wasn’t FDA-recognized-even though they had ISO 9001 certification. That’s not a mistake. It’s the rule. The FDA doesn’t accept just any audit. It has to be from their list.

If they can’t fix it? The shipment must be destroyed or shipped out of the U.S. within 90 days. And if they don’t? Penalties can hit up to three times the value of the goods. For a $900,000 shipment, that’s $2.7 million in fines.

Who’s Getting Hit the Hardest?

The impact isn’t spread evenly. Of the 89 facilities caught under the GLP-1 Import Alert, 73 are in India. Nine are in China. Seven are in Europe. That’s not because Indian manufacturers are worse-it’s because they supply most of the world’s generic APIs. The U.S. imports over 80% of its active ingredients from abroad, and India is the biggest source.

But here’s the twist: 22.1% of the shipments that got refused actually met pharmacopeial standards. They were safe. But their paperwork was wrong. A missing signature. A typo in the batch number. A CoA that didn’t include all required impurity limits. The FDA doesn’t care if the drug works. If the paper trail isn’t perfect, it gets blocked.

Some companies are trying to game the system. ProPublica found 157 products have received enforcement exemptions since 2013-including ones from companies with ongoing violations. One Singaporean intermediary was warned for falsifying export documents to avoid destruction penalties. It’s a risky move. The FDA is watching.

What It Costs to Get Back in Good Standing

Getting off the Red List isn’t just about fixing one batch. It’s about proving your whole operation changed. The FDA requires four steps:

1. A full, unannounced facility inspection (minimum five days)
2. A root cause analysis with a detailed corrective action plan (CAPA)
3. Three consecutive shipments that pass inspection without issues
4. Executive certification signed by the company’s top quality officer

On average, it takes 11.7 months to get removed from an Import Alert. Some take over two years. The most successful petitions? Those that include video evidence of their fixes-like showing new equipment being installed or staff being trained. Companies that only submit documents have a 42% approval rate. Those with video? 87%.

Many are spending $200,000 to $500,000 on blockchain traceability systems to meet the new batch-level transparency rules. Pfizer, for example, used the MediLedger network across 17 suppliers and boosted its Green List acceptance rate to 99.8%.

The Bigger Picture: Global Changes and Future Rules

This isn’t just an American issue anymore. The European Medicines Agency (EMA) is moving toward a similar system, planning to adopt FDA-style API screening by mid-2026. China’s NMPA just announced that starting January 1, 2026, all API exporters must meet FDA-equivalent certification standards to sell into the U.S. market.

Market changes are happening fast. Novo Nordisk’s manufacturing partners gained 18.7% market share in six weeks. Viatris reported a $417 million revenue hit. Prices for compounded GLP-1 drugs in the U.S. jumped 14.3% in November 2025. And big players are buying up capacity: Catalent paid $980 million for Novasep’s peptide business to secure supply.

The FDA isn’t done. Commissioner Dr. Robert Califf said in November 2025 that the GLP-1 alert model will be extended to all high-risk biologics-starting with monoclonal antibodies in Q1 2026. That means companies making cancer drugs, autoimmune treatments, and gene therapies will soon face the same scrutiny.

What This Means for Patients and Pharmacies

Some worry this will cause drug shortages. And yes, there’s been disruption. But the FDA’s point is this: a shortage of safe drugs is better than a flood of dangerous ones. The 2023 semaglutide shortage was caused by high demand. The current crisis is caused by unsafe supply. The FDA is trying to stop the latter.

For patients, this means fewer risky online purchases. More drugs will come from trusted manufacturers. But it also means higher prices and longer waits. Pharmacies are seeing fewer generic options. Compounded versions are getting more expensive. Insurance companies are adjusting formularies.

For manufacturers, the message is clear: if you want to sell to the U.S., you must invest in compliance-not just in equipment, but in people, training, documentation, and transparency. There’s no shortcut. The Green List isn’t a reward. It’s the new baseline.

What Comes Next?

By 2027, McKinsey estimates 65-75% of global API manufacturers will need to spend $500,000 to $2 million to meet U.S. standards. That’s a massive shift. Smaller suppliers may not survive. The industry will consolidate. And the FDA will keep tightening the rules.

For now, the Green List is the only way forward. If you’re a manufacturer, get on it. If you’re a pharmacy or distributor, verify your suppliers are on it. If you’re a patient, know that the drug you’re taking is being held to a higher standard than ever before. The system isn’t perfect. But it’s working.
