usability – Whole product page, how to increase trust and interaction?

This is a set of thousands of products.

This information is not entered manually, but it is only one product out of 100,000. Adding more descriptive details to these products is not really an option.

The problem I see: I'm not sure I can trust this site myself.

  1. How will they collect the payment?
  2. Is it trustworthy?
  3. Is this really the material I need?
  4. Is it really in stock?
  5. How much does it cost me to deliver?

How could you improve this design for UX?

Or what is the thinking process that should be done to improve this design?

subjective thoughts and recommendations more than welcomed
