Common structures are a deposit by T/T with the balance before loading, or a letter of credit through banks. The deposit should follow a written offer that lists the machine, attachments, Incoterm and inspection terms.
Pay to the company account named on the contract and invoice, never to a personal account, and keep the bank details verified through a second channel. If a seller pushes for full payment before any inspection or video, treat that as a warning sign.
Ask us for the model, tonnage or destination you have in mind — we reply with matching units and an FOB or CIF quotation.
