It would be wrong to tell you a structured product is free. The issuer builds its margin, its hedging costs and its distribution costs into the terms of the note itself, which shows up as a slightly lower participation rate, a slightly tighter cap, or a slightly lower coupon than a cost-free version of the same structure would offer.
You will not see this as a line item, because it is not charged as one. It is expressed in the terms you are quoted. That is how these instruments work, at every issuer.
