Chongming Container House Production

There are container house production-related businesses in Chongming, but they mainly focus on the trading and modification of second-hand containers, as well as the sales of modular houses. There is no clear evidence indicating the presence of large-scale container house manufacturing enterprises. Here is a detailed analysis:

I. Second-hand Container Trading and Modification Business

Shanghai Shiqian Container Service Co., Ltd. is registered with the Chongming District Market Supervision and Administration Bureau. It mainly engages in the trading of second-hand containers, including wing containers, refrigerated containers, and special containers. It also provides container mobile homes and customized container services. This indicates that there are modification and reuse businesses based on second-hand containers in Chongming, but they mainly focus on the trading and functional upgrading of the containers themselves, rather than the overall production and manufacturing of container houses.

II. Modular House Sales Business

There are modular house sales businesses in Chongming District. For example, globally sold modular houses include a 72-square-meter modular house (a three-story duplex luxury residence) and a 168-square-meter modular house (steel-structure houses, business hotels, etc.), with price ranges of 1.06 million - 1.08 million yuan and 2.48 million - 2.52 million yuan respectively. Although these modular houses use containers as design elements, they belong to the category of prefabricated houses. Their production may involve the structural modification of containers, but they place more emphasis on the overall design and integration of the houses, which is different from traditional container house production (internal decoration based on standard containers).

III. Container House Rectification and Supervision

The Xianghua Town Comprehensive Administrative Law Enforcement Team in Chongming District has carried out multiple special rectification campaigns for container houses that have been modified into residential structures. It focuses on investigating hidden safety hazards such as unauthorized electrical wiring and the illegal use of liquefied petroleum gas cylinders, and takes measures such as relocation and separation for non-compliant locations. This indicates that there are container houses in use in Chongming, but they are mostly temporary or illegally modified, rather than being produced on a large scale.

IV. Business Scope Changes and Potential Production Capacity of Enterprises

Shanghai Huailin Construction Engineering Co., Ltd. added container sales, manufacturing, and maintenance services to its business scope on September 10, 2025. However, its core business is the comprehensive treatment and reuse of construction waste, and the container business may be a supporting service. It has not yet demonstrated large-scale production capacity.
