FDA Inspections at Ports of Entry: How to Prepare for a Smooth Release

Introduction

Importing FDA-regulated products into the United States requires more than clearing U.S. Customs. Foods, cosmetics, medical devices, drugs, dietary supplements, radiation-emitting products, and many other commodities must also pass a separate FDA compliance review at the port of entry.

A smooth FDA release depends on preparation, accuracy, and understanding how the agency evaluates shipments. This guide outlines what importers should know in 2025 to avoid delays, detentions, and refusals.

1. Why FDA Review Happens at Ports of Entry

When an importer files an entry with CBP through ACE, the data is simultaneously transmitted to the FDA through ITDS. FDA uses this information to determine:

• whether the product is FDA-regulated
• whether the manufacturer or facility is properly registered
• whether the product appears compliant with U.S. safety and labeling laws

If the submission is incomplete or the product is considered high-risk, FDA may hold the shipment for document review, physical examination, sampling, or testing.

2. Know Whether Your Product Is FDA-Regulated

Every importer must confirm whether the HTS code triggers an FDA requirement. The HTS often includes FDA “FD” flags:

• FD1, FD2, FD3, FD4 indicate FDA jurisdiction.
• FD4 generally covers foods.
• FD2 covers drugs, devices, cosmetics, etc.

However, intended use may also trigger FDA oversight, even without an FD flag.

Stile Associates always recommends verifying both HTS classifications and intended use early in the supply chain.port paperwork) with digital tools and logistics workflow to deliver speed, transparency and control.

3. Preparing Before Arrival: The Key to a Fast Release

Accurate Entry Filing

FDA relies heavily on data accuracy. Errors lead directly to holds.

Your entry must include:

• precise product description
• correct HTS classification
• manufacturer information
• FDA registration numbers (if applicable)
• country of origin
• Affirmation of Compliance (AofC) codes, when required
• Prior Notice for foods

FDA verifies the data through automated screening within ACE/ITDS.

Supplier and Facility Compliance

Many delays occur when the manufacturer is unregistered or has a history of violations.

Importers should confirm:

• facility registration (food, drug, device, etc.)
• that labels meet FDA requirements
• that certificates of analysis (when applicable) match the shipment

A preventive approach saves time and money.

4. Monitoring Status During the FDA Review

Once the entry is transmitted, importers must monitor the status through ITACS (FDA’s Import Trade Auxiliary Communications System).

Through ITACS, you can:

• upload requested documents
• check “Documents Required” status
• check “Hold for Examination” status
• review the updated release status

Physical Examination or Sampling

If FDA selects the shipment for physical exam or sampling:

• the cargo must be accessible
• the importer must provide support at the warehouse
• the product cannot enter commerce until FDA releases it

Sampling does not guarantee release; results must first show compliance.

5. Important Updates in 2025

Nationalized Entry Review (NER)

Since 2024–2025, FDA reviews entries nationally, not just locally. A high-risk manufacturer, product type, or country may trigger national review delays even if the local port is operating efficiently.

https://www.fda.gov/industry/fda-import-process/entry-review

SERIO+ Modernization (2026 Ready)

FDA is gradually transitioning to SERIO+, a new integrated system that centralizes risk assessment, sample management, and communication. Full implementation is expected March 2026.

This modernization increases scrutiny of:

• repeat violators
• high-risk food categories
• unregistered facilities
• incomplete documentation

Being compliant from the start is more important than ever.

6. What Not To Do While the Shipment Is Under Review

• Do not move goods into commerce until FDA issues a release.
• Do not recondition or relabel goods without FDA authorization.
• Do not ignore document requests; delays increase the chance of detention.

Premature distribution can lead to recalls, penalties, or refusal of future shipments.

7. If Your Shipment Is Detained or Refused

A refusal occurs when the FDA determines that the product appears to violate U.S. requirements. Common causes include:

• misbranding
• adulteration
• unregistered facility
• contamination concerns
• labeling deficiencies
• incorrect documentation

Importers may:

• submit a reconditioning proposal
• correct documentation
• relabel or test the product under FDA supervision
• or re-export the shipment

5. Respond quickly to any “Documents Required” notifications.
6. Monitor ITACS continuously during the clearance process.

Frequently Asked Questions (FAQ)

FDA Inspections at Ports of Entry – Stile Associates

1. Why does the FDA review shipments at U.S. ports of entry?

The FDA verifies that imported products comply with U.S. health, safety, and labeling requirements. When the importer files an entry with CBP, the data is automatically shared with the FDA, which screens it for accuracy, risk, and regulatory compliance.

2. What types of products require FDA review?

Foods, beverages, dietary supplements, cosmetics, over-the-counter drugs, prescription drugs, medical devices, biologics, radiation-emitting products, and some chemical substances may require FDA oversight.

FDA guidance: https://www.fda.gov/industry/fda-import-program

3. Does an HTS code automatically determine FDA jurisdiction?

Not always. HTS codes often carry FDA flags (FD1–FD4), but intended use can also trigger FDA regulation even if the HTS has no FD flag. This is one of the most common causes of import delays.

4. What is ITACS and why is it important?

ITACS (Import Trade Auxiliary Communications System) allows importers to:

• upload requested documents
• check FDA review status
• confirm whether documents or exams are required
• ITACS status updates help you avoid unnecessary delays.
• More information: https://www.fda.gov/industry/import-program/using-itacs

5. How long does an FDA review take?

Most compliant and low-risk shipments clear within hours.

Reviews take longer when:

• manufacturers are unregistered
• documents are missing or inaccurate
• goods are selected for sampling or physical inspection
• the product type is considered high risk
• Under the Nationalized Entry Review (NER), delays may occur due to national risk patterns, not only local port workloads.

6. Can my goods be distributed before FDA release?

No. Even if the goods clear CBP, the importer cannot distribute or sell FDA-regulated items until FDA formally releases the shipment. Premature distribution can result in recalls, penalties, or future refusals.

7. What happens if my shipment is selected for FDA examination?

FDA inspectors may request physical access to the goods, collect samples, or review labeling. The cargo must remain intact until the FDA completes its evaluation.

Sampling does not guarantee release; results must be reviewed and approved.

8. What should I do if FDA requests documents?

Respond immediately through ITACS. Delayed or incomplete responses significantly increase the chance of detention.

Typical documents include:

• labels
• certificates of analysis
• facility registration
• product formulas
• prior notice confirmations

9. What is the most common cause of FDA delays?

The top causes include:

• incorrect or incomplete entry data
• unregistered or unverified foreign manufacturers
• labeling errors
• missing Affirmation of Compliance codes
• prior notice issues for food products
• Stile Associates strongly recommends reviewing documentation before departure.

10. What if my shipment is detained or refused?

You may:

• submit a reconditioning proposal
• correct documentation
• relabel goods under supervision
• re-export the product
• A refusal generally means the product appears to violate FDA law.
• FDA refusal details: https://www.fda.gov/industry/import-program/refusals

11. Does the new SERIO+ system change the review process?

SERIO+ is FDA’s modernization effort, integrating data and risk analysis into a single platform. It increases consistency and strengthens risk-based targeting. Full rollout is expected in 2026.

Importers should expect more data-driven scrutiny.

12. How can Stile Associates help?
