An agreement has been reached for 8.5 tons of dried shiitake mushrooms and dried black fungus, manufactured by Liangdang County Green Enriching People Industry Development Co., Ltd. in Longnan City, Gansu Province, to be exported to Bulgaria. This marks a milestone in the export history of these fungal products from Longnan to Bulgaria. The success is attributed to the supportive guidance and efficient customs clearance by Tianshui Customs under Lanzhou Customs. The customs has provided comprehensive assistance, including on-site services, quality management advice, and detailed explanations of Bulgarian market access conditions, to ensure compliance with Bulgarian standards and facilitate smooth export. This initiative is part of Lanzhou Customs' ongoing strategy to facilitate the export of more Gansu specialty agricultural products into the international market.
