Hello Carl, I am not sure what type of product you are dealing with, but I believe the following to be generally true. 1) Since the UL Mark will not appear on the product which is modified, you are most likely not violating any agreements with UL by modifying it.
2a) Yes you can build products prior to UL approval. Once approval is attained on a representative unit, then these products may be marked per UL's authorization. Please note: if a design change is required for UL approval of the representative sample, the instruments on the manufacturing floor will have to be modified prior to application of the UL Mark on the product. 2b) Yes a manufacturer can build and send a product without applying the UL mark if the customer is willing to accept it. Customer requirements and local legislation may prevent the customer from installing or operating the instrument, so the customer needs to decide whether or not he/she can accept the shipment. Compliance with UL standards is mostly a customer or market driven requirement. It is not legally mandated that producers apply the UL mark. Most legislation I have come across is more along the lines of a city ordinance that requires UL or other NRTL marks on items installed in public facilities. Many stores and businesses have their own internal requirements for equipment purchased.

A modification made to an approved product without notification to UL of the change; and with the intent of not applying the UL mark when shipping the product 2. A manufacturer certified to perform their own UL compliance subject to verification by UL, can the manufacturer build systems while waiting for final approvals; and would it be possible for the manufacturer to build and ship such a product without applying the UL mark? I hasten to add, this is a hypothetical and educational question!
