Can you appeal if you disagree with the CN code recommendation issued by the Customs Laboratory?

You can ask the Customs Laboratory to classify your goods to double-check the commodity code you use or plan to use. However, the recommended product code might differ from yours, and you may disagree with it. What should be done in such a case? Should you ignore the recommendation of the Customs Laboratory? Or is it better to appeal against it? And, in general, is it possible to appeal against such non-binding conclusions? The Supreme Administrative Court of Lithuania (SACL) clarified the latter issue.
