What Happens During Customs Inspection of My Goods?

Your container has arrived and your agent tells you it has been selected for examination. What does that mean? Will your goods be damaged? How long will it take, and will it cost more?

Customs inspection is a normal part of international trade. Understanding what happens during customs inspection helps you prepare, reduce delays and avoid problems.

Key takeaways

• Nigeria Customs uses risk management to select shipments for scanning or physical examination.
• A physical examination often takes 1–5 days, mostly waiting for container positioning.
• Accurate declarations, neat packing and clear labels make inspections faster.
• AEO status reduces the likelihood of inspection.

Why Customs inspects goods

Nigeria Customs Service inspects cargo to:

• Confirm goods match the declaration, description, quantity, value and origin.
• Check the HS classification is correct.
• Detect prohibited or restricted items.
• Prevent smuggling, fraud and security threats.
• Protect revenue by identifying undervaluation.
• Enforce standards and health rules with partner agencies.

How shipments are selected for inspection

Not every shipment is physically examined. Nigeria Customs uses risk management to decide. Factors can include:

• Importer history, compliance record and past offences.
• Type of goods, high-risk or high-duty items attract more attention.
• Country of origin and route.
• Declared value compared with reference prices.
• Document quality and consistency.
• Intelligence alerts.
• Random selection to keep the system fair.

Trusted traders under the Authorised Economic Operator (AEO) programme generally face fewer inspections. See the NCS AEO portal.

Types of customs inspection

1. Documentary check

Officers review your declaration, invoice, packing list, Form M, PAAR, bill of lading and permits. Many shipments are cleared at this stage.

2. Non-intrusive inspection (scanning)

Containers pass through X-ray or gamma-ray scanners. Officers compare the image with the declared goods. If the scan matches, the container may be released without being opened.

3. Physical examination

The container is opened and goods are checked. This can be:

• Partial examination, a sample of packages is opened.
• Full examination (100% check), all goods are unloaded and checked.

4. Laboratory testing

For some products, chemicals, food, pharmaceuticals, petroleum products, samples may be tested to confirm composition or quality.

What happens during a physical examination, step by step

1. Selection notice, your agent is informed the shipment is marked for examination.

2. Container positioning, the terminal moves the container to the examination bay. This alone can take time on busy days.

3. Joint examination, Customs officers examine goods with your agent present. Other agencies may attend where relevant, such as SON, NAFDAC, NAQS or security agencies.

4. Unstuffing, goods are unloaded fully or partially.

5. Verification, officers check descriptions, quantities, markings, origin labels and condition.

6. Findings recorded, the examination report is prepared on the Customs system.

7. Outcome: - Goods match: examination is closed and clearance continues. - Minor discrepancy: reassessment and possible additional duty (debit note). - Serious discrepancy or prohibited goods: goods may be detained or seized.

8. Restuffing and release, goods are loaded back and the container proceeds to release.

How long does customs inspection take?

• Scanning: often same day to one day, depending on queues.
• Physical examination: often 1–5 days, including positioning, examination and reporting.
• Laboratory testing: days to weeks.

The examination itself may take only hours. Most of the time is spent waiting for container positioning, officer availability and follow-up processes.

Does inspection cost extra?

Usually yes. Common costs include:

• Terminal charges for moving and positioning the container.
• Labour for unstuffing and restuffing.
• Additional storage while waiting.
• Possible demurrage if the delay runs beyond free days.
• Laboratory fees, if testing is required.

How to prepare for customs inspection

• Declare accurately, the best preparation is a declaration that matches the goods exactly.
• Pack neatly and consistently, similar items together, not mixed cartons.
• Label every carton with product name, quantity and country of origin.
• Provide a detailed packing list showing contents of each carton.
• Load for easy access, ask your supplier to load product types in blocks.
• Keep product specifications and catalogues ready for technical goods.
• Have permits ready for partner agency checks.
• Ensure your agent attends and understands the goods.

Partner agency checks during inspection

Depending on the goods, other agencies may take part in examination or require separate checks:

• SON, for regulated products needing SONCAP conformity.
• NAFDAC, for food, drugs, cosmetics, medical devices and chemicals.
• NAQS, for plants, animals and agricultural products.
• Security agencies, for sensitive or suspicious cargo.

The National Single Window, live since March 2026, is designed to coordinate these agencies' processes and reduce duplicated checks. In practice, having every permit ready before arrival is still the best way to avoid repeat inspections.

What happens if there is a discrepancy?

Not every discrepancy is fraud. Common findings include:

• More or fewer cartons than declared.
• Products of a different model or specification.
• Undeclared accessories or samples in the container.
• Goods that should be under a different HS code.

Minor honest errors usually lead to amendment and reassessment, often with a debit note for extra duty. Serious or deliberate misdeclaration can lead to detention, seizure and penalties under the Nigeria Customs Service Act 2023. Respond quickly, provide supporting evidence, and work with an experienced agent.

Can goods be damaged during inspection?

It can happen, particularly with fragile goods or poor repacking. Reduce the risk by using strong packaging, clear "fragile" markings and ensuring your representative supervises unstuffing and restuffing. Take photographs before and after. If damage occurs, see how to handle damaged goods.

Frequently asked questions

Why was my container selected for physical examination?

Selection is based on risk factors such as goods type, value, history and document consistency, and sometimes random selection.

Can I be present during customs examination?

Your licensed customs agent usually represents you. Importers can often arrange to attend or send a representative.

What if Customs finds goods not declared?

Expect reassessment, possible penalties and, for serious cases, seizure.

Does AEO status stop inspections?

It reduces the likelihood but does not eliminate inspections entirely.
