Product variations and continuation
We have a product A and have successfully applied for registration. Later, we added new models, changing A to A1, and adding A2 and A3. Can we still sell A?
According to the "Medical Device Registration and Filing Management Measures," adding a model (A2, A3) or changing the existing model (A to A1) constitutes a "permitted matter change" in the registration certificate. [^1] Once you submit your change application and it is approved, the newly issued registration certificate or change document will clearly list all currently approved models. Please check the latest registration documents immediately. If the model numbers listed on this new document are A1, A2, or A3, then the original model "A" is no longer an approved product in the legal sense. From the date of the change approval, you lose the legal right to continue selling model "A."
We must clarify a common misconception. Many companies believe that as long as a product is manufactured within the validity period of the original registration certificate, it can be sold until the end of the product's shelf life. This understanding is incorrect when a "registration change" occurs. When a model (A) is replaced by a new model (A1) on the registration certificate, the registration status of the old model (A) is immediately terminated. Continuing to sell "A" will be considered selling an unregistered medical device, which is strictly prohibited by the "Medical Device Supervision and Administration Regulations." The legal risks include heavy fines, confiscation of illegal gains, and even suspension of production and business. [^2]
So, can you still continue to sell "A"? The only possibility is that when you initially applied for the change, you clearly indicated to the NMPA that "A" would remain a separate model number, while "A1" was a new, parallel model number, and the NMPA approved this. In this case, your new registration certificate should list A, A1, A2, and A3. If "A" is missing from the registration certificate, then the answer is absolutely no—you can no longer sell "A."
As a CEO, the best practices for mitigating this legal risk are: First, before submitting any registration change application, the RA team must thoroughly coordinate with the marketing and inventory teams to clearly define the disposition plan for the old models. Second, once the registration change is approved, the RA department must promptly and accurately disseminate the latest registration certificate information (especially the list of approved models) to quality, production, warehousing, and sales departments. Third, the quality system (in accordance with GB/T 42061-2022, Good Manufacturing Practice for Medical Devices) must have a clear process for immediately identifying and isolating inventory of the discontinued model (A) as "defective" or "to be disposed of," strictly prohibiting it from entering circulation. [^3] Ignoring the internal management of this handover point is the root cause of many companies being caught with serious violations during unannounced inspections.

How to present Variant Certificates to clients
The details you mentioned (a "registration certificate" and two "change documents") are crucial. This is exactly the standard "license change" process in China's medical device regulatory practice. Your description of the nature of the documents is completely correct. My previous answer was based on the assumption of "renewal of the certificate." Now, based on your accurate description, I will give you the most accurate operational guidance. The core of this issue is still the "document control" principle in the "Good Manufacturing Practice for Medical Devices." [^1]
First, we must clarify the legal relationship between these three documents. The "Medical Device Registration Certificate of the People's Republic of China" (we call it the "main certificate") is the most fundamental "identity card" of your product. It stipulates the product's registration number, basic information, and validity period. The two "Medical Device Change Registration Documents" (we call them "Change Document 1" and "Change Document 2") are attachments and amendments attached to the "main certificate." The key point is that "Change Document 2" (approving A1-A4) replaces "Change Document 1" (approving A1 and A2) in terms of legal effect.
Therefore, "Change Document 1" is now an "obsolete document." It is no longer legally valid because the product model list it describes (A1, A2) has been updated by "Change Document 2" (A1-A4). According to the document control requirements of GMP and GB/T 42061-2022 (ISO 13485), you must "prevent the unintended use of obsolete documents." [^1] Presenting an obsolete change document to a customer is a serious compliance defect that misleads the customer and exposes your internal management chaos to the regulatory authorities.
So, how should you present it to the customer? You must provide a "document package" (Registration Package), which must contain only two documents:
- "Medical Device Registration Certificate of the People's Republic of China" (Main Certificate): This document is used to prove the legitimacy of your product registration number, basic product information, and (most importantly) that it is still valid.
2. "Medical Device Change Registration Document" (the latest change document, which approves A1-A4): This document is used to prove that the specific model (e.g., A3 or A4) purchased by your customer is the model legally approved under the "Main Certificate".
This "document package" (main certificate + latest change document) together constitutes the current, unique, complete, and legal registration certificate for your product. When your customers (hospitals or distributors) perform the "purchase inspection" obligations required by the "Medical Device Operation Supervision and Management Measures", they need to check these two documents simultaneously to ensure that the product is within the validity period and its model and specifications are consistent with the registration approval. [^2]
Your RA department must take immediate action: First, recall "Change Document 1" (the one that approves A1 and A2) from all distribution channels (sales, marketing, and quality departments); Second, stamp the recalled "Change Document 1" with an "invalid" stamp and archive it, and it must not be used for external display; Third, the standard operating procedures (SOPs) should stipulate that all registration materials provided to customers must be a combination of controlled copies of the "main certificate" and the "latest change document".
