HS Codes for Container Houses and Light Steel Villas

The common HS code for container houses is 9406000090, and the HS code for light steel villas is usually 9406900090. Here are the specific details:

HS Code for Container Houses
The HS code for container houses should be determined based on a comprehensive assessment of their structure, purpose, and materials. If their design meets the criteria for "prefabricated temporary buildings" (e.g., movable, modular assembly, and suitable for living), they are typically classified under 9406000090. This code corresponds to "other prefabricated temporary buildings" and covers detachable and reusable temporary structures made of metal or non-metal materials. For example, a house converted from a standard shipping container that retains its original frame structure and is used for living or office purposes falls under this code. It should be noted that if the container house is used solely as a shipping container (without modification for living space), it may be classified under Chapter 86 as transportation equipment, but such cases do not fall within the category of houses.

HS Code for Light Steel Villas
The export declaration for light steel villas typically uses 9406900090 (a 10-digit code), which corresponds to "other prefabricated temporary buildings". Their key features are as follows:

1. Structural Materials: The main frame is made of light steel structures, combined with metal or non-metal panels (such as color-coated steel sheets, OSB panels, etc.).
2. Functional Positioning: As permanent or semi-permanent residential buildings, they are equipped with complete living facilities.
3. Assembly Method: They adopt a modular design and can be assembled on-site or lifted as a whole.
   This code belongs to the same Chapter 9406 as that for container houses, but light steel villas emphasize the "villa" attribute, meaning they have higher design complexity, living comfort, and structural stability. If light steel villas are exported as prefabricated components (e.g., only exporting steel frames or wall panels), further classification is required based on the specific materials (e.g., steel structural components under Chapter 7308).

Key Bases for Code Selection

1. Purpose Priority Principle: If the product is clearly intended for living or office use, prioritize Chapter 9406; if it is for transportation or storage, classify it under transportation equipment codes.
2. Material Proportion: When metal structures account for more than 50%, they are usually classified under metal pressure vessels or steel structure codes; if non-metal materials such as wood or plastic dominate, the code needs to be adjusted.
3. Processing Depth: Incompletely assembled building components (e.g., only exporting steel beams or wall panels) may be declared under codes such as "other metal pressure vessels" or "building metal components".

When declaring for customs clearance, it is recommended to confirm the code by referring to the product specification, design drawings, and the customs classification ruling (Binding Ruling) to avoid delays in customs clearance or fines due to incorrect classification.
