December 18th, 2025 the Medical Device Authority (MDA) released for consultation the Second Edition of the Definition of Medical Device Guidance Document (MDA/GD/0006). This document provides critical clarifications on the definitions of medical devices, accessories, components, and spare parts under the Medical Device Act 2012 (Act 737).The feedback period runs from 4 December 2025 to 18 December 2025. The guidance aims to harmonize Malaysian regulations with Global Harmonization Task Force (GHTF) recommendations and resolve long-standing ambiguity regarding the regulatory status of replacement parts and auxiliary products.
KEY ELEMENTS OF THE DEFINITION OF MDA MEDICAL DEVICE GUIDANCE DRAFT INCLUDE:
Clarification on “Accessories” An accessory is now explicitly defined as an article intended to be used with a “parent” device to enable or extend its capabilities. Crucially, the guidance states that an accessory is regulated as a medical device in its own right. It requires separate registration, labeling, and conformity assessment, potentially carrying a different risk classification than the parent device.
Exemption for “Spare Parts” A spare part is defined strictly as a replacement for an identical or functionally equivalent part used for repair or maintenance after the device has been placed on the market. These items are not classified as medical devices and do not require approval under Act 737 for importation or placement in the market, provided they do not modify the device’s original specifications.
Definition of “Components” Components are defined as parts integrated during the pre-market manufacturing phase to enable the device’s function. They are not considered medical devices and are controlled through the manufacturer’s quality management system (QMS) rather than individual registration.
The “Battery Rule” (Component vs. Spare Part) The guidance clarifies that items like rechargeable batteries or chargers are considered components when packaged with the main device. However, if the same items are supplied subsequently as replacements, they are treated as spare parts, meaning they do not require separate registration if they are identical to the approved components.
WHAT MDA MEDICAL DEVICE GUIDANCE DOES THIS MEAN FOR YOU?
For manufacturers of medical devices, the Second Edition of the Guidance Document signals a shift towards stricter categorization but greater logistical flexibility for after-sales support.
- Audit Your Inventory: You must verify if items currently sold as “parts” meet the new definition of Accessories. If so, they must be registered individually to ensure compliance.
- Streamline Repair Logistics: The clear exemption of Spare Parts from registration requirements means you can fast-track the importation of repair parts without the regulatory burden previously associated with “device components.”
- Update Labeling: Ensure that accessories are labeled according to their specific classification and that your parent device’s instructions for use (IFU) clearly list supported accessories to avoid off-label risks.
While the guidance is still a draft open for consultation until 18 December 2025, manufacturers should prepare for these definitions to become the standard for regulatory control in Malaysia.
