Buying SIP panels directly from Suppliers in China.

[Raju Balakrishnan]

I am in planning phase for a cottage style small resorts in California. Planning to use OSB SIP building for small units of size 900 sq: ft, primarily for fast build and energy efficiency. Sourcing directly from China is cheaper, though more complex. But  effort is worth it as once the first unit is done it will be a copy-paste.  This will be like a normal site built home on foundation (not modular) going through regular inspections and permits, but using SIPs instead of sticks. 

1. Any experience/thought on buying directly from China, (The panes seems compliant with IRC, etc and probably can make sure that they are complient with Californa Residential Code  etc also)?

2. OSB vs Other type of SIP panels (fiber/steel), pros and cos?
