There are several reasons why Moroccan customers require a Certificate of Origin (COC):

Tariff preferences: Morocco may have signed trade agreements or free trade agreements with other countries or regions. These agreements may include provisions for tariff preferences on specific goods. By providing a Certificate of Origin, Moroccan customers can benefit from the tariff reductions or preferential treatment stipulated in these agreements.

Non-tariff trade barriers: Some countries impose non-tariff trade barriers on imported goods, such as quota restrictions or import license requirements. The Certificate of Origin can provide clear proof of the goods' origin and help avoid these non-tariff trade barriers that could restrict or delay the goods.

Assurance of quality and credibility: The Certificate of Origin serves as an official document certifying the origin and production process of the goods. Moroccan customers may want to ensure that the purchased goods meet specific quality standards and come from reliable suppliers or producing countries. The Certificate of Origin provides an additional guarantee of the goods' quality and credibility.

Import procedural requirements: Moroccan customs authorities may require a Certificate of Origin as one of the necessary documents for importing goods. This is to ensure the legality of the goods and compliance with the country's import requirements. The absence of a Certificate of Origin may result in the goods being refused entry or delays in the import process.

Therefore, providing a Certificate of Origin is crucial to meet the needs of Moroccan customers and ensure smooth international trade. It will facilitate Moroccan customers' access to trade benefits and help them avoid restrictions from non-tariff trade barriers.
