Our suppliers generally require prepayments from us before delivery of goods or service. It usually takes 3 to 6 months for the suppliers to deliver raw material for our equipment production and takes up to 6 to 12 months for the suppliers to deliver the construction materials. The prepayment is necessary to secure the supply in the market or secure a favorable price.
