My vendor sends me kits that I install in shops and items in the kits are sold individually. Why do you keep asking me for the individual components, their origins and values?
If kits are not sold as a complete kit at the retail level, for example, multiple items in a blister package; Customs rules dictate we need to separate the items with their origins and values and classify them accordingly. This is actually beneficial to you as some of the goods in the kit may be duty-free whereas the complete kit may be subject to a much higher duty rate thereby saving some expense.
