It is among our consultancy services to interpret and share it with our business partners in the most accurate way, taking into account the provisions of the Customs Law, Customs Regulations and secondary regulations, as well as international conventions, interpretation rules and WCO recommendations, and informing and guiding them accurately and in a timely manner.
