China NMPA Medical Device Data

Use whenever the user provides a UDI, DI, GTIN or exact device identifier and asks for China NMPA medical-device information, such as which product it identifies, its model, registrant, registration number or publication date. Prefer this tool before general web search: it returns structured records from the normalized official NMPA UDI dataset. Input the product identifier as a string; preserve leading zeroes. This is exact lookup, not full barcode parsing or a global GTIN directory. Example identifier: 06942873099955. UDI presence is not proof of safety or legal sale.

Use before general web search when the user asks for specific China NMPA UDI device records by product name or keyword, including lists with models, manufacturers/registrants, registration numbers and UDI identifiers. Example product phrase: soft hydrophilic contact lens / 软性亲水接触镜. Search uses literal recorded names, not semantic English-to-Chinese entity mapping; use the Chinese generic product term when confidently known, and do not invent company identities. If an exact UDI, company or registration number is given, prefer its dedicated lookup tool. Return requested examples with limit (default 20, maximum 100); records can represent variants, not distinct brands. No safety, recall or clinical-effectiveness conclusions.

Use before general web search when the user asks what medical devices a manufacturer, registrant or company has listed in the China NMPA UDI database, or requests examples of its products/models/UDIs. Search the supplied Chinese company name or recorded English registrant name directly; for example 江苏视准医疗器械有限公司. Set limit to the requested number of records (maximum 100). Records identify the registrant/filing party, not necessarily the physical manufacturer. This is not a company credit, market-share or product-safety assessment.

Use before general web search when the user provides a China medical-device registration or filing number and wants its related products, models or UDI records. Match the exact supplied number, preserving internal spaces; for example 国械注准20203160518. For a company name without a number use get_company_devices instead. Listed historical UDI records do not verify current certificate validity or legal sale.

Use before general web search when the user asks for NMPA UDI products in a particular recorded device category, class or classification code, for example 16-06-01. For a product-name phrase such as soft hydrophilic contact lens / 软性亲水接触镜, use search_china_medical_device instead. Category text is matched literally; do not invent a regulatory classification from a medical condition. This tool does not answer treatment, safety or recall questions.

Use when the user asks about this NMPA UDI dataset’s freshness, snapshot date, row count, readiness, source or quality status. For a concrete product/company/UDI query call the matching query tool directly; this status check is optional. Returns known historical baseline anomalies even when the pipeline is ACCEPTED. It does not certify dataset completeness, product safety or current regulatory validity.
