Key Takeaways
- Flat Rack (20' FR / 40' FR): Ideal for over-width and over-height industrial machinery, boilers, and vehicles requiring heavy-duty lashing.
- Breakbulk Clearance Thailand: Used for heavy project cargo lifted directly onto lowbed trailers at the port quay under customs supervision.
- Machinery Customs Compliance: Importing CNC machines (HS 8457–8459) or drilling rigs (HS 8430) requires technical catalogs, serial number verification, BOI e-MT releases (if promoted), or Temporary Import bonds for short-term project equipment.
1. Flat Rack (FR) vs. Open Top vs. Breakbulk Shipping
- Open Top Container (OT): Has four walls and a removable tarpaulin roof for over-height cargo loaded vertically by crane.
- Flat Rack Container (FR): Has only end bulkheads and a reinforced floor, accommodating over-width and over-height Out-of-Gauge (OOG) machinery.
- Breakbulk Cargo: Non-containerized project cargo stowed in the vessel hold or on deck, requiring direct port-side handling and customs inspection.
2. Customs Clearance of CNC Machines & Drill Rigs in Thailand
- CNC Machine Customs Clearance (HS 8457 / 8458): Importers must provide engineering catalogs showing machine functions, model numbers, and serial plates. BOI-promoted factories must secure an e-MT machinery release before filing the customs entry.
- Customs Entry and Clearance of Drill Rigs (HS 8430): Rotary drilling rigs and construction equipment imported temporarily for specific engineering projects can utilize Thai Customs Temporary Import procedures (with a bank guarantee or duty deposit) and re-export upon project completion.
