I'm looking to get a proforma invoice for an FCL (40HQ) shipment to CIF Iquique, Chile. Specifically, I need a total of six units, divided equally between two different models. It's essential that the invoice covers all shipping costs to ensure a smooth transaction. Could you please provide the detailed pricing, including unit costs and any additional fees? Also, let me know about the estimated shipping timeline and any documentation required on my end. Your prompt response would be greatly appreciated, as I'm keen to move forward with this order soon. Thanks!
