If one or more of your products is not covered by the Waste Electrical and Electronic Equipment (WEEE) Regulations, it is recommended that you keep documentation which explains your reasons for this decision. If this is difficult, it may be because your product is covered by the regulations. You should go back and check that your product really is outside the scope of the WEEE Regulations - see how to check whether WEEE producer responsibilities apply to you.
You should also remember that if the intended use of your product changes, you will need to review whether this change will bring it within the scope of the WEEE Regulations.
It's also a good idea to make sure that your sales staff understand and can explain why your business doesn't have to comply with marking or financing responsibilities for any product that you have decided is outside the scope of the WEEE Regulations.
