Tell the supplier what will happen to the hair after purchase. Loose hair intended for ventilation may need a different handling and preparation discussion from hair intended for braiding or another product-making process. The application helps identify which characteristics are critical, but it does not justify assuming an unprovided technical result.
Describe any further processing you expect to perform and ask whether the proposed material is appropriate. Do not label the hair unprocessed or suitable for every chemical service simply because it is sold without an attachment. Bulk describes the form of supply, not a guarantee of processing history or geographic origin.
