Traceable bird's nest is a high-end grade. Traceable bird's nest refers to bird's nest with the origin of bird's nest and legally and legally exported with the approval of China Quality Inspection Bureau. It's a double-protected bird's nest, high-end grade. The authentic traceability code of bird's nest is beige or beige. Because it is picked by hand, there is a little bit of swallow hair residue, which will be different at different times due to different colors in different places of origin. Traceable bird's nest refers to the bird's nest products that have been legally imported and exported after the origin of China bird's nest and the quarantine examination and approval of China Academy of Inspection and Quarantine. Every small package of traceable bird's nest is labeled with CAIQ traceability label, which realizes the "special factory number" and "one product and one yard" of imported bird's nest products. This label represents the safety of bird's nest products, not the quality. In order to obtain traceability labels, Yanwu and processing plants that produce bird's nest must register with the government of origin and relevant departments in China, and pass inspection and supervision. At the same time, each batch of bird's nest has to go through a series of sampling, inspection and quarantine, sample preparation procedures when it is sent out and arrived, and the samples can only be labeled and sold in the market after passing the inspection.
