To provide an accurate quotation, please share the wire dimensions, insulation type, thermal class, required quantity, packaging requirements, and destination country.

If the order quantity does not meet the MOQ requirement, we can also produce it for you, but the price will be higher than the MOQ price. Generally, it is calculated based on 3-5 times the MOQ unit price multiplied by the order quantity that you need, and plus a startup/module fee of 1,500 RMB. (If the total price of samples is higher than the MOQ price, then we will follow the total price of MOQ)
