How to Ship Container Houses by Sea

Shipping container houses by sea involves steps such as selecting full container load (FCL) transportation, clarifying cargo information, completing packing and customs declaration, arranging sea transportation and transshipment, and customs clearance and pickup. Details are as follows:

I. Select Full Container Load (FCL) Transportation
Container houses are relatively large in volume, so FCL transportation is usually required, which means a single container is loaded with goods from only one shipper. Common specifications include 20-foot (about 28 cubic meters) and 40-foot (about 58 cubic meters) standard containers. The container type should be selected according to the size, weight, and packaging method of the house. For example, a 20-foot container has a weight limit of about 22 tons, and a 40-foot container has a weight limit of about 26 tons. Overweight cargo requires additional fees or may be refused for loading.

II. Clarify Cargo Information and Packaging
It is necessary to confirm the attributes of the house (such as whether it contains dangerous goods like lithium batteries or chemicals), its size, weight, and protection requirements. For fragile items, pallets and stretch wrap should be used for reinforcement. For oversized items, it should be confirmed whether open-top containers or flat-rack containers are required. Packaging should comply with international maritime standards. For example, wooden packaging should be fumigated and marked with an IPPC logo to prevent the spread of pests and diseases.

III. Packing and Customs Declaration
During packing, the cargo should be fixed and cushioned to prevent displacement due to ship摇晃 (shaking) during sea transportation. The shipper or customs broker should submit documents such as an export customs declaration form, invoice, packing list, and contract to the customs. After customs clearance, the container can enter the terminal yard to wait for loading onto the ship. For example, containers from Dongguan usually depart from Shekou Port in Shenzhen or Nansha Port and arrive at the destination port after transshipment at Yantian Port or Hong Kong.

IV. Sea Transportation and Transshipment
Shipping container houses by sea requires multimodal transportation. For example, containers shipped to Toronto first arrive at eastern coastal ports such as Halifax or Montreal and are then transshipped to the inland port of Toronto by rail or inland barge, adding about 5 to 7 days. During winter when Lake Ontario freezes, the unloading port may be changed to Quebec City, extending the overall time by 7 to 10 days.

V. Customs Clearance and Pickup
After the container arrives at the destination port, customs clearance procedures should be completed. Canadian customs will conduct risk screening based on the electronic customs declaration form submitted by the shipper, focusing on checking the cargo name, value, origin, and whether it involves anti-dumping duties. After customs clearance, the consignee can pick up the cargo and arrange for subsequent assembly or use.
