HOW IS YOUR PRICE COMPARED WITH MANUFACTURERS OR OTHER USED EQUIPMENT SUPPLIERS?

Our second-hand machines are sourced from offical and legal channels, such as local dealers and construction companies all over China with low working hours. We have a professional team of Chinese and foreign engineers for repairs and maintenance, they are fully tested before sale. So our well-maintained machines are in excellent condition with reliable performance and ready to work. From numerous comparison and feedbacks from clients, our price is more competitive than others.

HOW IS YOUR DELIVERY TIME?

In general circumstance, we can have an immediate delivery of regular machines for our clients within 7 days, because we have a variety of resources to check machines in stock, locally and nation widely, and to receive machines in timely manner. But for manufacturers/factories, it will take more than 30 days to produce the ordered machine.

HOW SOON CAN YOU RESPOND CLIENT INQUIRIES?

Our team is consisted of a group of diligent and dynamic people, working 24/7 to respond client inquiries and questions all the time.

Most problems can be solved within 8 hours, while manufacturers/factories will take much longer to give response.

WHICH PAYMENT TERMS CAN YOU ACCEPT?

Normally we can work on T/T term or L/C term, sometime DP term.

1. On T/T term, 30% down payment is required in advance, and 70% balance shall be settled before shipment, or against the copy of original B/L for long-term cooperating client.

We are a professional and sophisticated international player, can handle all INCOTERMS 2010 terms, and we normally work on regular terms such as FOB, CFR, CIF, CIP, DAP HOW LONG WILL YOUR PRICE BE VALID?

We are a tender and friendly supplier, never greedy on windfall profit. Basically, our price remains stable through the year. We only adjust our price based on two situations: (1) The rate of USD: RMB varies significantly according to the international currency exchange rates; (2) Manufacturers/factories adjusted the machine price, because of the increasing labor cost and transportation cost.
