Unfortunately that is not the case across the entire tariff - hence the confusion.

Thanks, my question is really around how to know whether to use a national or a union code (not specifically which code). This is for importing and claiming preference for any trade agreement on import into the UK. Since the tariff does not specify which ('national or union') should be used and the trade agreement also does not - how do I know if I should apply a national or a union code?

Thanks Customs Oldtimer - I still dont feel this explains how you would know to choose U110 or 9001 since the trade agreements do not specify.
Also under what circumstances would you need to use multiple preference codes?

Thanks - so how do I know which one is required at which time? For example when making a claim to preferential origin. How do I know if I should use U110 or 9001? What does it depend on?

What is the difference between 'union' codes and 'national' codes in CDS data element 2/3 - and how do you decide which one is appropriate?
