ポータブルタイニーハウスの需要が2026年に急増している理由（そしてそれが購入者にとって何を意味するか）

Importing a Portable Tiny House: Customs, Shipping, and Certification

Importing a portable tiny house internationally is more straightforward than most buyers expect — but getting the details right upfront avoids significant delays and costs.

Shipping and Logistics

• Container sizing: Most portable tiny house components ship in 20ft or 40ft HC (high cube) containers. A 40ft HC fits roughly 400-600 sq ft of components depending on complexity.
• Shipping time: China to USA West Coast — 14-21 days. China to Europe — 25-35 days. China to Australia — 18-25 days.
• Freight cost: $2,500-$5,500 per 40ft container, depending on origin and destination port (2026 rates). Fuel surcharges vary.
• Port to site: Inland transport from port to site must be planned. Oversize loads may require special permits.

Import Duties and Taxes

• USA: Prefab wooden structures typically fall under HS code 9406. Current duties range from 0-7.5%. Consult a customs broker for China-origin goods given tariff changes.
• EU: 2.7% standard duty plus VAT at destination country rate.
• Australia: 5% general tariff rate plus 10% GST. Free trade agreement rates may apply.

Documentation Required

1. Commercial invoice with HS code classification
2. Packing list (detailed, component by component)
3. Bill of lading or airway bill
4. Certificate of origin
5. Phytosanitary certificate (for timber products — confirms treatment for pests)
6. Technical specifications and structural drawings (for building permit application)

Work with a freight forwarder experienced in timber structure imports. The $1,000-$2,500 fee typically saves multiples of that in avoided documentation errors and delays.
