Our company has an old customer from Peru. He has purchased chemical products from our company many times. Because he is very satisfied with our product quality, delivery time and service every time. We have established a long-term and stable cooperative relationship. This time, the product that the client purchased from our company was sodium tripolyphosphate stpp. After the customer sent his requirements, we gave him quotation quickly. “Your price is very competitive in our local area”, said by the customer. Then, we communicated about the specific packaging and packing volume, and the customer quickly placed an order of a container(27MT) of stpp powder.
