   Research specific regulatory requirements related to textiles, safety, and labeling in your target countries—such as CE marking in Europe or local import standards in Africa and South America. Request suppliers to provide relevant compliance certificates and product testing reports. Emphasize sustainability standards, such as organic certifications or eco-labels, especially if your market values environmentally friendly products. Incorporate sustainability clauses into contracts and consider working with suppliers committed to transparent supply chains. Regular audits and certifications help maintain compliance and support your market positioning as a responsible importer.
