Can my [company removed] export industrial valves to a sanctioned country via Dubai without penalties?

It is not possible to determine the implications of this matter definitively without first reviewing the full detailed information, such as the destination country for the sale, the authority that imposed the sanctions, whether this product is in fact subject to those sanctions, and the exact nature of the goods involved. Based on that, we can identify the most appropriate course of action to ensure that your business is conducted in a lawful and compliant manner.
