- For the major container ports such as Los Angeles / Long Beach, Seattle, Vancouver, Houston, Savannah and New York, the number of reefer slots is proportional to the amount of container traffic. This implies that the reefer business is a part of their function as commercial gateways to the North American market.
- There are a number of smaller ports that are offering a larger number of reefer slots in relation to their total containerized traffic. This implies a level of specialization in the reefer business, either for exports (Oakland, Jacksonville, Halifax) of for imports (Wilmington, Port Everglades, Philadelphia, Hueneme).
