The safety of imported shortening is still a key content in port supervision and inspection. For port scientific regulation, accurate inspection, safe and fast clearance, food safety assurance and trade development promotion, 94 laboratory analysis certificates, health certificates and plant quarantine certificates that must attached in 47 batch of shortenings imported from Indonesia from May 2019 to June 2020 were studied comparatively with ISO/IEC17025, shortening and their relevant Chinese national food safety standards. The results showed that 4 laboratories’ certificate of shortening analysis had 12~20 testing items, the components of the sample test date were incomplete or different, and 3 of them did not indicate the test date. 2 laboratories’ test certificates did not indicate the testing and conformity assessment which were obtained based on Chinese national food safety standards; 1 laboratory issued two kinds of analysis certificates (5 copies of which cited or 10 copies of which did not cited Chinese national food safety testing and conformity assessment standards); Invalidation standard citation or cited standards were too many and inaccurate. The solvent residue conformity assessment was carried out according to GB2716:2005, and there was a risk of exceeding the standard. The antioxidant application conformity assessment method did not specify the requirements of GB2760A, A.2, and there was a risk of exceeding GB2760 limits. The core content of the health certificate was expressed in a variety of ways, which was not standardized and unified. The plant quarantine certificate did not indicate the scientific name, Latin scientific name of plant varieties and the shortening production (press) time.
