FDA warning letter: Harbin Jixianglong Biotech Co., Ltd.
What the FDA told Harbin Jixianglong Biotech Co., Ltd. in May 2026 about semaglutide and tirzepatide — and whether it has been resolved.
“In addition, we reviewed your firm’s drug listing submissions in FDA’s electronic Drug Registration and Listing System (eDRLS) and found that you failed to provide drug listing information for your relabeled semaglutide as required under section 510(j) of the FD&C Act, 21 U.S.C. 360(j), and 21 CFR Part 207.”
What an FDA warning letter is
It is a letter. The FDA writes to a company to say which of its practices the agency believes break the law, and asks it to fix them. That is the whole mechanism: a written notice, published so anyone can read it.
It is the FDA’s position, not a court’s finding. The company can reply, and can disagree. The agency states in these letters that failing to address the problems may lead to further action such as seizure or an injunction — which tells you the letter itself is not yet either of those things.
A warning letter does not recall a product, suspend a licence or close a business. It does not mean that medicine already dispensed was unsafe. When the FDA is satisfied the problems are fixed, it publishes a closeout letter.
What it does tell you is that a regulator looked at this company and wanted something changed. The useful question is what — and the quoted passage above answers it more precisely than any summary can.
