17It should be noted, at the outset, that, when the Court is requested to give a preliminary ruling on a matter of classification for customs purposes, its task is to provide the national courts with guidance on the criteria which will enable the latter to classify the products at issue correctly in the CN, rather than to effect that classification itself. The description, for classification purposes, of the goods at issue is the result of a purely factual finding which it is not for the Court to make in the context of a reference for a preliminary ruling (judgment of 28 April 2022, PRODEX, C‑72/21, EU:C:2022:312, paragraph 27 and the case-law cited).
