Customs Declaration Name for Container Houses

The customs declaration name for container houses can usually be declared as 'mobile house', and its corresponding customs code (HS code) is mostly 9406900090. Here is a detailed explanation of the customs declaration names for container houses:

• Classification and Characteristics of Container Houses
  Container houses are architectural forms transformed from containers, featuring mobility, reusability, and rapid assembly. Depending on their purpose and structural differences, they can be classified into types such as packing-box container houses, light-steel-frame houses, and functional sentry boxes. Their core structures typically employ steel frames, paired with fireproof and thermal insulation materials (such as polyurethane sandwich panels and rock wool boards), and pre-installed water and electricity pipelines to meet temporary or long-term living needs.

• Basis for Selecting Customs Declaration Names
  According to customs classification rules, the customs declaration name for container houses should be determined based on their functional attributes. If the house uses a container as its main structure and has complete living functions (such as interior decoration and water and electricity facilities), it should be declared as a 'mobile house' as a priority. This declaration method aligns with the customs definition of modular buildings and generally has a lower tariff rate than pure steel structure products. For example, specific categories such as 20-foot container houses and multifunctional container houses can all be uniformly classified as 'mobile houses'.

• Applicability of HS Codes
  Customs code 9406900090 corresponds to 'other mobile houses', covering categories such as prefabricated buildings and modular houses. If a container house adopts a non-standard container structure (such as a light-steel-frame house), further differentiation is required based on materials and processes:

  • Houses primarily made of steel and mobile are applicable to 9406900090;
  • Wooden or mixed-material houses require material descriptions and may apply to other codes (such as those in the 9403 category).

• Customs Declaration Precautions
  When declaring, the specific purpose, material composition, and size specifications of the house must be clearly stated on the customs declaration form. For example, label it as '20-foot container mobile house (steel frame + polyurethane sandwich panel)' to avoid inspection delays due to incomplete information. Additionally, if the house includes electrical equipment or special functional modules, additional certification documents (such as CE certification) are required.
