Your container arrives at Port Miami. The bill of lading is clean. Everything looks normal. Then you get a call: "Your cargo's on hold for a customs exam."
Now what? How long will it take? Who pays? Can you avoid this in the future?
If you've imported through Miami, you've probably been there. Let's break down exactly what happens when CBP (Customs and Border Protection) flags your container, why they do it, and what it costs your timeline and wallet.
What Is a Customs Exam (or "Physical Exam")?
A customs exam is when CBP physically inspects your container's contents to verify:
- The cargo matches the entry paperwork (commodity codes, quantities, descriptions)
- Prohibited items aren't hidden inside
- Tariff classifications are correct
- You're not illegally importing restricted goods
- No health/safety violations (FDA, EPA, etc.)
CBP has authority to examine any container, anytime. But they don't examine everything—they use risk assessment algorithms to target high-risk shipments.
Why Does CBP Flag Containers?
CBP's automated system flags containers based on:
Entry Factors
- Commodity codes — Restricted items (textiles, footwear, ceramics, certain chemicals)
- Country of origin — High-risk jurisdictions get extra scrutiny
- Value anomalies — Price too low? Possible duty evasion
- Repeat issues — Your company has prior violations? You're on the list
Shipper/Importer History
- Previous customs violations or penalties
- Trade compliance issues (late filings, incorrect docs)
- FDA import alerts on your products
- Prior seizures or detentions
Port/Terminal Factors
- Random selection (CBP samples containers for baseline audits)
- Intelligence tips (law enforcement referrals)
- Inspection quotas (yes, this happens)
Pro tip: The dirtier your history, the higher your future risk scores. Clean up violations early.
The Exam Process at Port Miami
Here's what actually happens:
1. Hold Status (1–4 hours after arrival)
Your container is flagged in the CBP system. Terminal holds it in the yard. You get a notification from your freight forwarder/broker.
2. Scheduling (Same day or next business day)
CBP sets an exam appointment. Port Miami has dedicated exam piers where containers are moved for inspection.
3. Physical Exam (2–8 hours)
CBP officers open the container, inspect the cargo, verify against the entry, and document findings. If you hired a customs broker, they usually attend to answer questions.
4. Release or Action
If everything checks out: Release in hours. If CBP finds discrepancies: violations, re-entry required, penalties, or seizure (worst case).
Timeline: How Long Does a Hold Take?
This depends on the type of exam:
Exam-Only Hold (Most Common)
- Schedule: 1–3 business days
- Inspect: 2–4 hours
- Total: 3–5 business days
FDA Food Exam (If Applicable)
- Additional wait: +2–7 business days
- Reason: FDA runs its own inspection at a separate facility
- Total: 1–2 weeks
Antidumping/Countervailing Duty (AD/CVD) Review
- Wait: +14–30 days
- Reason: CBP verifies tariff classification; if challenged, goods stay held while ITC investigates
Who Pays? The Real Costs
Drayage Costs
- Extra container movements: $200–$400 (from dock to exam pier, back to dock)
- Chassis rental (if extended): +$150–$300/day for detention
Port Fees
- Free exam fee: Usually included (CBP covers it)
- Extended storage: $50–$150/day if the hold goes beyond free time
Customs Brokerage
- Extra filing: $150–$500 (amended entries, re-exports, etc.)
Lost Time & Disruption
- Delayed delivery to destination
- Warehouse rescheduling
- Customer dissatisfaction
A typical hold might cost $500–$1,500 in direct fees, plus operational delays.
Types of Holds: Know the Difference
Customs Hold (CBP)
Your issue. CBP is concerned. Usually resolves once exam is done.
FDA Import Alert
Food & beverage. FDA has safety concerns about a supplier. Your entire shipment gets held indefinitely until FDA clears the facility.
ICE Seizure
Intellectual property (counterfeit goods). Commerce enforcement. Worst-case scenario—container seized, goods destroyed, fines assessed.
DEA Hold
Chemical precursors or drugs detected (or suspected). Investigate separately; extreme delays.
Know which agency has your cargo. Different agencies = different timelines and procedures.
How to Avoid or Minimize Holds
Preventative Measures
- Accurate filings: Double-check commodity codes and descriptions. Wrong HS code = red flag.
- Clean history: Resolve violations quickly. Previous seizures follow you for years.
- Licensed broker: A good customs broker knows CBP's risk patterns and files defensively.
- Pre-clearance: For food/pharma, coordinate with FDA/CBP pre-arrival inspections if possible.
At the Terminal
- Transparent labeling: Clear product labeling inside makes exams faster.
- Documentation packet: Supplier invoices, test certificates, origin docs—keep everything accessible.
- Broker attendance: Have your broker present during the exam to answer questions on the spot.
After Release
- Review CBP findings: If CBP noted something, fix it on future shipments.
- Re-file if needed: If the exam revealed classification errors, amend the entry proactively.
What If Your Container Gets Seized?
Worst case: CBP finds violations and seizes the container.
- Counterfeit goods: ICE destroys them. You get nothing back.
- Health/safety violations: FDA destroys. No recovery.
- Documentation errors: Entry gets denied; you can re-export (if it's re-exportable) or abandon to CBP.
- Tariff undervaluation: CBP assesses penalties (20% of invoice value, sometimes more). You pay to release.
Don't let it get this far. Fix compliance issues early.
The Bottom Line
Customs holds are part of Miami import operations. A basic exam? 3–5 days, $500–$1,000. A complex exam with FDA or tariff issues? 2–4 weeks, $2,000+.
The best strategy:
- File accurately from day one
- Work with a licensed customs broker
- Keep your compliance record clean
- Be transparent with CBP
