Customs at various ports in China have increased inspection of durians, with the process expected to take 2-14 working days. The inspection aims to detect heavy metals and alkaline yellow, with the latter being recently mandated by Kunming Customs. The Thai Ministry of Agriculture has also clamped down on the use of non-compliant chemical substances in Thai durians exported to China. This has led to concerns among exporters and buyers about potential suspension for non-compliance and uncertainty in export procedures. The laboratory detection time for Basic Yellow 2 residue standard is also a concern, as it could lead to fruit quality deterioration and increased storage costs. The high price of durians, especially with the approaching Chinese New Year, and the low southern region production compared to the eastern region, especially Chumphon Province, further complicate the situation.
