To ensure market access and ethical sourcing, verify that suppliers comply with ISO 2451 standards for cocoa bean specification and quality. For premium markets, certifications such as Rainforest Alliance, UTZ, or Fairtrade are essential as they validate sustainable farming practices and labor conditions. Furthermore, ensure the product meets SPS (Sanitary and Phytosanitary) measures, specifically regarding heavy metal limits (like Cadmium) and pesticide residue levels, which are strictly regulated in the EU and North America.
