Container House Transshipment Regulations

Container house transshipment regulations mainly cover aspects such as size suitability, structural stability, installation procedures, packaging compliance, and transportation mode selection:

I. Size Suitability Requirements Folding container houses must meet the loading specifications of sea freight containers. After folding, their dimensions must fully conform to the internal dimensions of standard sea freight containers (e.g., the internal dimensions of a 20-foot container are approximately 5.89m×2.35m×2.39m, and those of a 40-foot container are approximately 12.03m×2.35m×2.39m), eliminating the need for additional custom transportation carriers. For example, container houses with a double-wing folding and expansion design are of standard size after folding. When expanded bilaterally through hydraulic or mechanical means, the space can be increased by 2-3 times, meeting both transportation requirements and usage efficiency.

II. Structural Stability Requirements Container houses must possess resistance to jolts and salt spray corrosion to adapt to the maritime environment. In terms of material selection, fire-resistant and heat-insulating materials such as fireproof rock wool boards should be used, and the overall structure must be able to withstand the dynamic loads during transportation. For example, Shaanxi Huateng container houses ensure safety during transshipment through designs that can withstand an earthquake intensity of eight degrees and winds of up to 11 levels.

III. Simplified Installation Procedure Requirements Container houses should support rapid deployment and retrieval, with the ability to complete hoisting and expansion within 1 hour of arrival at the destination without wet operations. For example, the integrated pre-assembly technology for the entire house allows all aspects such as structure, insulation, and water and electricity systems to be completed in the factory, enabling immediate use upon arrival and significantly improving transshipment efficiency.

IV. Packaging and Labeling Compliance Goods packaging must comply with international maritime standards: cardboard boxes must have sufficient load-bearing capacity, and wooden packaging must be fumigated and marked with the IPPC logo. Special goods (e.g., fragile items) should be labeled with transportation marks such as 'Fragile' and 'This Side Up'. Refrigerated goods must specify temperature requirements (e.g., -18°C for frozen food), and oversized items must confirm whether they exceed the internal dimensions of containers or require the use of open-top or flat-rack containers.

V. Transportation Mode Selection Depending on the destination distance and on-site installation conditions, options include full-container transportation, flattened and compressed transportation, or container cargo transportation. For example, after flattening and compression, each house is equivalent in size to a standard 20-foot container, saving one-fourth of the freight cost. A 40-foot high-cube container can transport six houses, significantly reducing logistics costs.
