Overall Import for Textile Products

We usually buy 5-10 tons of each item per month. But there is a very volatile demand right now. If we agree, we will conclude a contract for the supply of a trial batch of goods and if the quality suits us, we will regularly buy the specified quantity. What exactly needs to be clarified?

We only need 100% regular cotton that is use for work or polyester cotton mix which weighs 260gsm/m2 and 350gsm/m2.
