What Customs Inspectors Check in Perishable Shipments

What Customs Inspectors Check in Perishables

Understand what U.S. Customs, FDA, and USDA inspectors look for in perishable food shipments — and how to prepare your reefer cargo for fast clearance.

When your reefer container arrives at a U.S. port, it may be subject to inspection by CBP (Customs and Border Protection), FDA (Food and Drug Administration), or USDA (U.S. Department of Agriculture). For perishable goods — like seafood, meat, and produce — these inspections are designed to ensure food safety, accurate documentation, and compliance with import regulations. Knowing what inspectors look for helps you prepare in advance, reduce clearance delays, and protect your cold chain.

Documentation and Label Verification

Inspectors first check that all paperwork and labels match the declared shipment. Typical documents reviewed include:

Bill of Lading (BOL)

Commercial Invoice and Packing List

USDA or FDA Prior Notice

Health or Phytosanitary Certificates

Temperature Log and Data Recorder Report

They verify:

Product name, quantity, and origin country

Exporter and importer details

Consistency between documentation and physical cargo labels

Any mismatch may result in a Customs hold or FDA sampling.

Product Condition and Packaging Integrity

Next, inspectors check the physical state of the cargo:

Packaging should be intact, sealed, and properly labeled.

No signs of thawing, water damage, or contamination.

Pallets and cartons stacked to maintain airflow and temperature stability.

If product temperature is above the safe threshold, the load can be detained or refused entry.

Temperature Control Records

Temperature consistency is a key factor for perishable imports. Inspectors often request:

Reefer temperature log printouts

Data logger downloads

Proof of continuous power during transit (especially for long voyages).

A container showing temperature excursions or power loss may trigger a quality examination or lab testing.

Sanitation and Pest Control Compliance

Customs inspectors also ensure that containers are clean, pest-free, and sanitary. They check for:

Organic residue, foreign objects, or water pooling inside the container.

Evidence of pest infestation (flies, larvae, or insects).

Compliance with APHIS (Animal and Plant Health Inspection Service) import sanitation standards.

Containers failing these checks can be ordered for fumigation, reinspection, or re-export.

Labeling and Country of Origin Requirements

Every perishable food shipment must meet FDA and USDA labeling standards, which include:

Product name and scientific species name (for seafood/meat).

Net weight and lot number.

Exporter name and country of origin statement.

Handling/storage instructions (“Keep Frozen,” “Store Below –18°C”).

Accurate labeling prevents misbranding penalties and ensures traceability during recalls.

Random or Targeted Sampling

If the shipment is new, high-risk, or from a flagged exporter, inspectors may collect samples for lab testing. Testing may include:

Microbiological analysis (Listeria, Salmonella, E. coli).

Residue testing for antibiotics or chemicals.

Sensory inspection for odor, texture, or appearance.

Sampling delays typically range from 1 to 3 days, but can extend if the product category requires FDA laboratory confirmation.

Reefer Equipment Condition

Inspectors may check the reefer unit itself for:

Proper temperature display and operation.

Integrity of seals, plugs, and vents.

Evidence of leakage, rust, or contamination.

This ensures the container meets U.S. food-grade transport standards.

How to Prepare for a Smooth Inspection

Double-check all documentation before arrival.

Keep temperature logs and data logger downloads ready.

Inspect container cleanliness before loading.

Work with a USDA-approved cold storage to hold cargo if a customs exam is required.

Communicate with your customs broker immediately upon receiving an exam notice.

Conclusion

Customs inspections are an essential part of importing perishable food safely. By maintaining clear documentation, clean equipment, and accurate temperature records, importers can minimize delays, protect product integrity, and demonstrate compliance with U.S. food safety laws.
