Questions Overseas Buyers Ask Before Inquiry
To provide an accurate FOB or CIF quote, please share the target delivery port, intended quantity, model preferences (Foldable Office, Expandable Home, or Flat Pack), required insulation thickness, and any regional building code requirements (e.g., wind speed rating or snow load limits).
Standard models (such as Foldable Container Offices) usually ship within 10 to 15 business days. Customized expandable homes or bulk project orders typically require 20 to 30 days depending on component specs and custom interior finishes.
Yes. As a direct manufacturer, we offer complete OEM/ODM options including structural steel color customization, window and door placement alterations, pre-installed electrical standards (US/EU/AU specs), and interior room partitioning.
Every module is engineered with integrated ISO container corner castings and transport locking pins. Folded units are fully enclosed and corner-braced so they can be handled, stacked, and secured using standard container crane equipment without damaging internal pre-installed fixtures.
