How Do UDI and Product Classification Codes Affect Overseas Registration?

Answer: UDI and product classification codes affect overseas medical device registration by influencing registration dossiers, labeling, database submissions, post-market traceability, and change management. When registering in multiple countries, companies must confirm whether the target market mandates UDI, the applicable timelines, issuing agencies, packaging levels, Basic UDI-DI or UDI-DI maintenance rules, and whether the product classification code is consistent with the scope of application, models and specifications, and certificate information.

Scope of Application

Key Summary

UDI and product classification codes affect medical device registration dossiers, labeling, database submissions, post-market traceability, and product change management. When registering in multiple countries, companies must confirm whether the target market mandates UDI, the applicable timelines, issuing agencies, packaging levels, Basic UDI-DI or UDI-DI maintenance rules, and whether the product classification code is consistent with the scope of application, models and specifications, and certificate information.

Who Should Read This

This content is suitable for manufacturers, regulatory affairs personnel, overseas business leaders, and CRO teams that are planning overseas medical device registration, preparing to enter GHWP member states and key markets, or need to assess documentation gaps and registration pathways.

Assessment Logic

Companies should first clarify the target country, product risk class, intended use, existing registration basis, and commercial launch plan, and then determine the applicable regulatory pathway, depth of documentation, local authorized representative requirements, and post-market maintenance responsibilities. The same product may have different classifications and evidence requirements in different countries, and domestic registration conclusions cannot be applied mechanically.

Documentation Priorities

• Confirm the scope and implementation timeline of UDI in the target market.
• Organize packaging levels, models and specifications, and UDI master data.
• Verify whether the product classification code is consistent with the registration pathway.
• Include UDI changes in labeling and post-market maintenance processes.

Common Misconceptions

Common misconceptions include mechanically preparing documents based only on a checklist, failing to conduct product classification first, ignoring local authorized representative and labeling requirements, underestimating supplementary testing and translation workload, and treating the registration certificate as a one-time task while neglecting post-market maintenance.

AIMEILI Viewpoint

AIMEILI recommends that companies not treat UDI as a simple labeling task, but instead establish a correspondence among product master data, packaging levels, and certificate maintenance.
