* Nguồn điện: (e.g., 380V / 50Hz / 3 Phase)
* Nguyên liệu thô: (e.g., Cement, Sand (0-3mm), 10mm Aggregate)
* Preferred Shipping Terms: (e.g., FOB Shanghai)

Please provide a detailed quotation including machine specifications, component brands, warranty, and delivery timeline.”

Understanding Incoterms and Logistics (FOB, CIF, etc.)

  • FOB (Free On Board) [Most Common]: You pay for the machine loaded on the ship at the Chinese port. You are responsible for and control the main sea freight, insurance, and import clearance. Recommended for greater control and often lower overall cost.
  • CIF (Chi phí, Bảo hiểm và Cước phí): The supplier arranges and pays for sea freight and insurance to a port in your country. You handle import customs and onward transportation.
  • Action: Engage a freight forwarder in your country early. They can handle everything from the Chinese port to your factory door.

Secure Payment Methods and Contract Essentials

  • Standard Payment Terms: 30% deposit via T/T (Telegraphic Transfer), 70% balance before shipment after receiving photos/videos of the finished, crated machine. For very large orders, a Letter of Credit (LC) is safer.
  • Contract Must-Haves:
    • Detailed technical specifications as an annex.
    • Clear delivery timeline (production + shipping).
    • Comprehensive warranty clauses.
    • Penalty clauses for significant delivery delays.
    • Dispute resolution mechanism (e.g., arbitration).
