Dear Mr. Zheng:
On May 7, 12, & 14, 2026 the Food and Drug Administration (FDA) conducted a remote Foreign Supplier Verification Program (FSVP) inspection of Win Woo Trading, LLC located at 31056 Genstar Rd, Hayward, CA 94544.

This letter notifies you of our concerns and provides you an opportunity to address them. If you do not adequately address this matter, we may take further action. For instance, we may take action under section 801(a)(3) of the FD&C Act (21 U.S.C. 381(a)(3)) to refuse admission of the food you import for which you appear to be in violation of section 805. We may place the foods you import into the United States on detention without physical examination (DWPE) when you import the foods. You can find DWPE information relating to FSVP in Import Alert # 99-41 at http://www.accessdata.fda.gov/cms_ia/ialist.html. In addition, the importation or offering for importation into the United States of an article of food without the importer having an FSVP that meets the requirements of section 805 of the FD&C Act or the FSVP regulation is prohibited under section 301(zz) of the FD&C Act (21 U.S.C. 331(zz)).
You should respond in writing within fifteen (15) working days from your receipt of this letter. Your response should address the specific things you are doing to correct any violations.

If you believe that you are not in violation of the FD&C Act, include your reasoning and any supporting information for our consideration. If you cannot complete all corrections within 15 working days, you should explain the reason for your delay and state when you will correct any remaining violations.
