A4: For our standard products, usually it will take about 35-45 days for pressure boilers, and 25-30 days for atmospheric-pressure boilers. For non-standard products, time will be different and subject to the specifications of pressure, electricity, fuel, capacity, etc.

 Q5: What about your payment term?
A5: Our terms of payment is very flexible, we can discuss and meet your requirement. However, TT is the most welcome term and it has the priority to the price discount.

Q6: What kind of documents will be provided?

 Q7: What's your MOQ?
A7: Only 1 set, if you have more than that, you will get a more favorable price.

 Q8: How's the packaging & shipping
A8: For metal products like boiler body, steam header, tank, etc, they will be packed by stretch film; for accessories, they will be packed in wooden cases or carton boxes. We can handle all shipments including standard container, open top container, flat container, bulk carrier, etc. Because of big dimensions, not all boilers can be loaded into standard containers. For gas/oil boilers, bigger than 5 ton/hr or 3.5 MW can't be loaded into standard container. Frame rack (flat) container or bulk carrier will be applied.
