1. Sesame seeds are primarily imported via sea freight. Taking Africa as an example: transit times typically take around 45 days. Due to the extended shipping duration, thorough dehumidification must be conducted before shipment to prevent mold growth

2. Moisture damage and mold contamination fall under insurance coverage. It is advisable to purchase relevant cargo insurance. Should port inspections reveal aflatoxin levels exceeding standards or quality deterioration due to moisture during transit, claims can be filed based on the inspection report.

3. Qingdao Port is China's largest sesame import hub, handling approximately 90% of the nation's imports, primarily sourced from African countries.

4. At major ports like Qingdao, customs clearance can be completed within 2 days if documentation is complete and the shipment is not selected for testing. However, clearance times will extend if laboratory testing is required.
