Every medical device legally sold in China carries an NMPA registration number — a standardized string that encodes the device’s regulatory status, approval year, and classification. Knowing how to read this number takes seconds once you understand the format, and it tells you more about a device’s regulatory standing than any marketing claim.
The Basic Format
The standard format for a Chinese medical device registration certificate number is:
国械注准YYYYNNNNNNN
国械注进YYYYNNNNNNN
Breaking this down:
| Component | Meaning |
|---|---|
国械注准 | Domestic registration — device manufactured in China |
国械注进 | Import registration — device manufactured outside China |
YYYY | Four-digit approval year |
NNN | Three-digit category/classification code |
NNNN | Four-digit sequential number within the year and category |
The seven digits after the year form a structured number, not a random sequence. The first two or three digits encode the device classification and product category from the NMPA’s Medical Device Classification Catalog; the remaining digits are the sequential registration index for that category within the approval year.
What the Category Prefix Tells You
The NMPA Classification Catalog assigns each device type a two-digit major category code. For medical robotics, the most relevant categories are:
- 01 — Active Surgical Instruments (surgical robots with active motion)
- 03 — Auxiliary Surgical Equipment (navigation and positioning systems)
- 21 — Orthopedic surgical instruments and related equipment (some orthopedic systems)
- 32 — Software as a Medical Device (SaMD — standalone software and AI-based systems)
In the full registration number, these appear after the year digits. A number beginning 2023301... points to a 2023 approval in category 30 (broadly: active implantable and active therapeutic devices including surgical robots).
Real Examples from the Chinese Robotics Market
国械注准20233010800 — Da Vinci Xi (China-manufactured)
The Da Vinci Xi Surgical System (China-Manufactured) made by Intuitive Fosun carries registration number 国械注准20233010800.
国械注准— domestic registration, manufactured in China2023— approved in 2023301— Category 30, subcategory 1 (active surgical instruments, Class III)0800— sequential number 800 in this category for 2023
国械注准20233010311 — VAS HERO Vascular Interventional Robot
The VAS HERO Neurovascular Interventional Robot carries registration number 国械注准20233010311.
2023— approved in 2023301— active surgical instruments at Class III0311— lower sequence number in the same year and category
The lower sequence number reflects an earlier approval date within 2023 compared to number 0800 — VAS HERO received its certificate in March 2023.
国械注准20253010500 — Carina Laparoscopic Surgical Robot
The Carina Laparoscopic Surgical Robot carries registration number 国械注准20253010500.
2025— approved in 2025301— active surgical instruments at Class III0500— sequential number within 2025’s active surgical instrument approvals
国械注进20243010155 — Ion Bronchoscopy System
The Ion Bronchoscopy System imported by Intuitive Fosun carries 国械注进20243010155.
国械注进— import registration (manufactured outside China, imported for the Chinese market)2024— approved in 2024301— active surgical instruments, Class III0155— sequential number
The 进 (import) designation means the device was not manufactured in a China-based facility, distinguishing it from domestically produced systems with the same parent brand.
国械注准20233211543 — AIJOINT Surgical Planning Software
The AIJOINT Surgical Planning Software carries 国械注准20233211543.
2023— approved in 2023321— Category 32, subcategory 1 — this is the Software as a Medical Device (SaMD) category1543— sequential number
The 32 prefix immediately identifies this as a software product rather than a hardware device. Standalone AI diagnostic and surgical planning software falls here regardless of whether it outputs to a robotic system or a screen.
How to Use the Registration Number
Verify authenticity. The NMPA publishes a searchable registration disclosure database at nmpa.gov.cn/zwfw/sdxx/sdxxylqx/. Entering the registration number returns the approved device name, manufacturer, indication, and certificate validity period. This is the definitive check on whether a device is actually registered.
Identify the approved indication. The registration certificate includes a specific intended use statement. This is the only clinical indication for which the device can be commercially promoted. Companies that reference clinical use outside their approved indication are in regulatory violation.
Check validity. Registration certificates are valid for five years from the approval year encoded in the number. A 2020 prefix indicates a certificate issued in 2020, valid until 2025 unless renewed. Renewal requires a fresh submission.
Distinguish domestic from import. 国械注准 and 国械注进 indicate different supply chains, pricing mechanisms, and post-market surveillance obligations. Import-registered devices must have a Designated China Agent responsible for post-market activities.
Provincial and Municipal Formats
Class I devices are filed at the municipal level and Class II at the provincial level. These carry different formats:
- Provincial (Class II):
[Province abbreviation]械注准YYYYNNNNNNN— for example,沪械注准for Shanghai - Municipal (Class I):
[City code]NNNNNNN— varies by city
This primer focuses on Class III national-level certificates (国械), which cover all surgical robots, Class III diagnostic devices, and implantables. For the regulatory process that produces these numbers, see How NMPA Class III Medical Device Approval Works in China.
Frequently Asked Questions
Are registration numbers recycled or reused?
No. Each registration number is unique and permanent. If a device’s registration expires and is renewed, the renewed certificate carries a new number with the renewal year. The old number becomes inactive.
Does the sequence number within a year indicate anything about device quality?
No. The sequence number reflects only the order in which registrations were finalized within a year and category. A lower number means earlier approval within that calendar year; it carries no quality implication.
How do I find the approved indication for a registered device?
The NMPA registration disclosure database returns the full registration certificate details by number, including the product name in Chinese, the legal manufacturer, the approved intended use (适用范围), and validity dates.
What does it mean when a company says a product is “NMPA pending”?
“Pending” indicates the manufacturer has submitted a registration application but has not yet received approval. A pending device cannot be commercially sold for clinical use in China. The expected approval timeline depends on whether the device qualifies for the NMPA Innovation Green Channel or is proceeding through standard review.
Is the CE Mark or FDA clearance number in a similar format?
No. Each regulatory jurisdiction has its own registration format. CE Marking uses a Notified Body number (a four-digit code identifying the certifying body), not a sequential device registration number. FDA 510(k) clearances use a format like K240123 (letter prefix plus six digits). For comparison of these regulatory pathways, see CE MDR vs MDD for Medical Robots and FDA 510(k) vs PMA vs De Novo Pathways Compared.
