Customs Code for Prefabricated Houses

The customs code for prefabricated houses needs to be determined based on the specific type. Common classifications and codes are as follows:

1. Movable Panel Houses
   Movable panel houses are typically classified under 9406.00.90, falling under the category of 'Other prefabricated buildings'. These houses often use light steel structures or metal frames, combined with materials such as color-coated steel sheets and sandwich panels. They are characterized by their detachability and ease of assembly, widely used in temporary construction scenarios (e.g., construction site dormitories, post-disaster resettlement). The coding is based on the internationally recognized Harmonized System (HS) of Commodity Naming and Coding, which covers non-fixed, movable prefabricated structures.

2. Saudi Customs Codes (HS9406 Products)
   Saudi Arabia has a more detailed classification for prefabricated buildings, primarily divided into three major categories:

   • HS940620000000: Steel modular building units. These products use steel as the main structural material and achieve rapid assembly through modular design, commonly found in industrial plants, commercial exhibition halls, etc. The '20000000' in the code specifically refers to steel materials, emphasizing the industrial nature of the structure.
   • HS940610: Prefabricated wooden building-related products. This includes wooden-structured houses, wooden wall components, etc., often used in villas, vacation homes, and other scenarios with special material requirements. The '10' in the code represents the wooden category, and it is important to note that the wood must comply with relevant quarantine standards (e.g., Saudi Arabia's requirements for insect treatment of imported wood).
   • HS940690: Covers prefabricated buildings made of materials such as plastic, metal, aluminum, and fiberglass. This code serves as a 'catch-all' clause, applicable to non-steel, non-wooden prefabricated structures (e.g., aluminum alloy houses, fiberglass-reinforced plastic houses). Further confirmation is needed based on the specific material to ensure compliance with the category definition.

Notes:

• The accuracy of the customs code directly affects customs clearance efficiency and tax calculation. It is recommended to make a comprehensive judgment based on the structural material (steel, wood, plastic, etc.), purpose (permanent/temporary), and assembly method (modular/integral transportation) of the house.
• Some countries may have additional certification requirements for prefabricated houses (e.g., Saudi Arabia requires compliance with SASO standards). It is necessary to confirm the technical regulations of the target market in advance.
• If the house includes electrical equipment or furniture, the corresponding codes must be declared separately to avoid misclassification.
