So maybe Jens, when a company claims that a product qualifies for this preferential rate or preferential origin, what are the key things to consider for them?

Yeah, and explaining the different systems to prove origin will already answer the utilization concern.

Because as I said, okay, in the beginning you have a clear framework, but as Maira said also, it's negotiated between trading partners, so you have different rules in different trade agreements itself.

Maybe first focusing on the claim for preferential origin itself and your proof that you need to submit to do the claim.

You have two different systems.

You have an importer-based system or an exporter-based system.

The importer-based system is quite new.

And I see Jens nodding a lot meanwhile, but maybe you also still want to add on.
