In asp with a sql db

I have a form I am creating. The purpose is to allow a user to create new part numbers in our item master databse. In the form there are "part number, class, description, and size." Rather than having them do this one at a time I would like to allow them to fill out a form with lines for upto 25 new parts. How can get the form to upload all the data even though some of it is repeating?
