Prefabricated House Export Process
The prefabricated house export process mainly includes four core stages: factory prefabrication, packaging and numbering, transportation and export, and on-site assembly, with customs providing full-process support.
I. Factory Prefabrication Stage
House production adopts a highly standardized model, with 90% of the processes completed on intelligent factory assembly lines. Through synchronized integrated assembly technology, modules such as walls, floors, doors and windows, waterproof layers, electrical systems, and bathroom cabinets are assembled with millimeter-level precision. This production method not only shortens the construction period but also reduces manual errors through centralized production, ensuring the uniformity of specifications for each module and laying the foundation for subsequent transportation and assembly.
II. Packaging and Numbering Stage
After the completion of individual modules, systematic packaging is required. Operations include loading the modules into large cargo containers and planning the entire chain of "packaging-numbering-inventory-installation logic" in advance. The numbering system must clearly indicate the module type, installation sequence, and corresponding position, while the inventory records the specifications and quantities of accessories in detail. This stage achieves visualization of the delivery system through digital management tools, preventing module misalignment or missing accessories during overseas assembly.
III. Transportation and Export Stage
A multimodal transportation model of "land + sea" is adopted: first, the cargo containers are transported to the port by special transport vehicles, and then exported to the target country via container liner ships. Customs departments provide crucial support at this stage: opening green channels through the "advance declaration + appointment inspection" mechanism, coordinating with the port to prioritize berth arrangements; employing a "field inspection + video surveillance + data comparison" three-in-one supervision method to achieve "non-intrusive" customs clearance during the loading process; guiding the port to adopt specialized lifting techniques and moisture-proof and shock-proof measures according to the characteristics of modular houses to ensure cargo safety.
IV. On-site Assembly Stage
Overseas on-site assembly offers significant advantages: it does not require bulk materials such as cement and sand required for traditional construction, and only a small number of construction personnel are needed to operate lifting equipment to splice the modules according to the numbering sequence. During assembly, the focus is on completing pipeline connections (including electrical and water supply and drainage systems) and structural fixation. Typically, the entire house can be assembled within a few days, achieving a "ready-to-live" delivery standard.
Customs Support System runs through the entire process: it grasps export plans in advance through the "customs-enterprise对接 (docking)" mechanism, optimizing the衔接 (connection) of customs declaration, inspection, and exit procedures; utilizing intelligent supervision systems to achieve real-time tracking of cargo status; formulating special safety plans according to the characteristics of modular houses, including ship stowage optimization and moisture-proof packaging standards, ensuring an over 30% increase in export logistics turnover efficiency.
