Classification Overview

The Four-Class System

Malaysia uses a risk-based classification system with four classes, aligned with the GHTF/IMDRF framework:

Class	Risk Level	Examples	Registration Route
Class A	Lowest	Tongue depressors, elastic bandages, non-sterile gloves	Notification (self-declaration)
Class B	Low–Medium	Hypodermic needles, suction catheters, blood pressure monitors	Full registration — standard dossier
Class C	Medium–High	Lung ventilators, bone fixation plates, haemodialysis systems	Full registration — enhanced dossier
Class D	Highest	Implantable pacemakers, HIV blood screening kits, spinal implants	Full registration — full design dossier

Classification Rules

Device class is determined by applying the classification rules in the Schedule to the Medical Device Regulations 2012. The rules are based on:

1. Duration of contact — transient (< 60 min), short-term (60 min–30 days), long-term (>30 days)
2. Degree of invasiveness — non-invasive, invasive, implantable
3. Body site — skin, orifice, blood pathway, central circulatory/nervous system
4. Active vs non-active — whether the device uses electrical or other energy sources
5. Special rules — for IVDs, software, combination products

If more than one rule applies to a device, the highest class takes precedence.

General Classification Principles

• Classification is based on intended purpose — the same physical device may be classified differently depending on what the manufacturer claims
• Accessories to a device are classified independently of the device itself
• Systems and procedure packs require each component to be individually classified
• A software that drives or influences a higher-class hardware device may be classified at that higher class

GHTF / IMDRF Alignment

Malaysia's classification rules are directly based on GHTF SG1/N045:2008 — Principles of Medical Device Classification. This alignment means that for many devices, the Malaysian class will be the same as or very close to the EU (MDR), Australian (TGA), Canadian (Health Canada), and Singaporean (HSA) class.

Use the ASEAN CSDT

If you are already registered in another ASEAN country using the Common Submission Dossier Template (CSDT), this dossier can be adapted for Malaysian submission with minimal additional effort. See ASEAN Harmonisation.

Classification Disputes

If there is uncertainty about the correct class for your device, you may:

1. Submit a classification enquiry to MDA via the MyMDA portal
2. Request a pre-submission meeting with MDA for complex or novel devices
3. Reference the classification rules in the Regulations 2012 and relevant IMDRF guidance

MDA's formal determination of class is binding for registration purposes.
