Tiny house caravan

When sourcing a Tiny House Caravan, the chassis and frame are the most critical components. Ensure the chassis is made of hot-dip galvanized steel to prevent rust and corrosion, especially for coastal use. For the wall structure, light gauge steel framing is preferred over wood for its strength-to-weight ratio and resistance to pests. Insulation is vital for livability; look for polyurethane (PU) sandwich panels or rock wool insulation with a thickness of at least 50mm to 100mm to ensure thermal efficiency in various climates.

Compliance varies by destination. For the US market, ensure the unit meets RVIA (Recreational Vehicle Industry Association) or NFPA 1192 standards. For Europe, look for CE marking and compliance with EU Whole Vehicle Type Approval (ECWVTA). Additionally, all electrical components must be certified (e.g., UL for USA, CE/TUV for Europe, SAA for Australia) and the plumbing system must adhere to local pressure and sanitation codes to pass customs and insurance requirements.

B2B buyers should verify the integration of solar power systems (inverters, controllers, and lithium batteries) and fresh/grey water tank capacities. For high-end models, check for incinerating toilets or composting systems which increase marketability. Ensure the supplier provides standardized external hookups (shore power and city water inlets) that match the voltage and plug types of your target country (e.g., 110V for North America vs. 220-240V for most other regions).

Confirm the Gross Vehicle Weight Rating (GVWR) and ensure it aligns with standard towing capacities. The caravan should be equipped with an AL-KO or equivalent braking system (mechanical or electric) and a heavy-duty jockey wheel. For international shipping, verify that the external dimensions (height and width) fit within a 40ft HQ container or are suitable for Flat Rack/Ro-Ro shipping to avoid exorbitant logistics surcharges.

The biggest risks include structural damage during transit and non-compliance with local road legality. Tiny houses are heavy and tall; if not secured properly in a container, internal fixtures can shift. Always mandate pre-shipment inspections (PSI) by third parties like SGS or Intertek to verify that the build matches the approved CAD drawings and that all waterproofing tests (rain tests) have been passed before the balance payment is made.

Focus on long-term scalability rather than just the initial unit price. Request a detailed Bill of Materials (BOM) to see exactly what brands of appliances and materials are being used. Negotiate for spare parts kits (extra glass panels, specialized hinges, or touch-up paint) to be included in the first shipment. For bulk orders, aim for a staged payment structure (e.g., 30% deposit, 40% after framing, 30% after final inspection) to maintain leverage over quality.

Due to the size, Ocean Freight is the only viable option. If the house is wider than 2.3 meters, it may require a Flat Rack container, which is more expensive. Ensure the supplier uses marine-grade protective film to wrap the entire unit to prevent salt-air corrosion. For the interior, all furniture must be bolted down or braced with foam blocks. It is highly recommended to purchase All-Risk Marine Insurance covering 110% of the CIF value.

Classify the product correctly under the HS Code (typically 871610 for trailers/caravans). You will need a Certificate of Origin, a VIN (Vehicle Identification Number), and a Manufacturer’s Statement of Origin (MSO). Consult a local customs broker to confirm if the unit will be taxed as a 'vehicle' or 'prefabricated building,' as this significantly impacts the import duty rates and VAT.
