    Refrigerated Shipping: Best Practices for Temperature-Controlled Freight

    Why Reefer Shipping Is Different

    Temperature-controlled freight, whether it's produce, pharmaceuticals, or frozen foods, demands precision at every stage. A single temperature deviation can result in thousands of dollars of spoiled product and potential regulatory violations.

    Pre-Shipment Preparation

    Know Your Temperature Requirements

  1. Frozen goods: 0°F or below
  2. Refrigerated produce: 33–40°F (varies by commodity)
  3. Pharmaceuticals: Often 36–46°F with strict tolerances
  4. Chocolate/confections: 55–65°F

    5. Pre-Cool Your Trailer

    The reefer unit maintains temperature. It doesn't cool warm product down quickly. Ensure:

  5. The trailer is pre-cooled to the required temp before loading
  6. Product is at the correct temperature before it goes on the truck
  7. Loading is done quickly to minimize warm air exposure

    8. During Transit

    Continuous Monitoring

    Modern reefer units offer real-time temperature monitoring via GPS-enabled sensors. At Your Shipping Guy, we ensure your reefer loads are tracked continuously with alerts for any temperature deviations.

    Proper Airflow

  8. Stack pallets to allow air circulation
  9. Don't block the airflow channels in the trailer floor
  10. Use load bars to prevent shifting that could block air paths

    11. Choosing the Right Carrier

    Not every carrier with a reefer trailer is qualified. Look for:

  11. Experienced reefer drivers who understand pre-trip inspections
  12. Well-maintained equipment: a breakdown means spoiled product
  13. Proper insurance covering temperature-sensitive cargo
  14. Compliance history with food safety regulations (FSMA)

    15. Cost Considerations

    Reefer rates are typically 15–25% higher than dry van rates. Factors that affect pricing:

  15. Distance and lane availability
  16. Season (summer rates are higher due to produce demand)
  17. Temperature requirements (frozen costs more than refrigerated)
  18. Multi-stop vs. direct delivery

    19. Protect Your Investment

    Temperature-controlled shipping is an investment in product quality. Working with a broker who specializes in reefer freight, and has relationships with vetted reefer carriers, is the best protection for your cargo.
