Share

A 10/21-10/24/2025 FDA inspection at the Yangzhou H&R Plastic Daily Chemical Company drug manufacturing facility in Hangji, Guangling, Yangzhou, Jiangsu, China, found significant violations of current good manufacturing practice (CGMP) regulations for finished drugs. A 3/18 Warning Letter says the violations were:

  • failure to have for each batch of drug product an appropriate laboratory determination of satisfactory conformance to final specifications for the drug product, including the identity and strength of each active ingredient, before release;
  • failure to conduct at least one test to verify the identity of each component of a drug product, and failure to validate and establish the reliability of a component supplier’s test analyses at appropriate intervals;
  • failure to establish adequate written procedures for production and process control designed to assure that manufactured drug products have the identity, strength, quality, and purity they purport or are represented to possess; and
  • failure of the firm’s quality control unit to exercise its responsibility to ensure that manufactured drug products comply with CGMP and meet established specifications for identity, strength, quality, and purity.

FDA says the firm’s quality systems are inadequate and recommends that it engage a qualified consultant to evaluate its operations and assist it in meeting CGMP requirements.

All of Yangzhou’s products were placed on a 2/13 Import Alert. The company was told to correct the violations promptly and to respond with a list of specific steps it has taken to address the violations and prevent their recurrence, with a schedule for completing the corrections.
