The Middle East may require conformity to local standards and import permits depending on the country. It’s essential to work with suppliers familiar with these regulations and ensure all documentation, including certificates of analysis and MSDS, are accurate and up-to-date. Collaborating with customs brokers experienced in these regions can streamline approvals and reduce the risk of shipment delays or penalties.
