Starting an Import/Export Business involves understanding key regulations and processes for both importing and exporting. For importing, businesses must understand regulations from Customs and Border Protection around documentation, duties, and tariffs. Key import documentation includes commercial invoices, certificates of origin, and letters of credit. For exporting, businesses must understand regulations from the Department of Commerce around export licensing, the shipper's export declaration, and the automated export system. Both importing and exporting require understanding pricing, marketing, distribution networks, and cultural considerations for foreign markets.
