Sri Lanka Device Classification: Dual-Track Class I–III and IVD A–D

1. Key takeaways

Sri Lanka operates two parallel risk classification systems: general medical devices are classified as Class I, Class IIa, Class IIb and Class III under the classification principles and rules of the European Union medical device legislation, while in vitro diagnostic devices (IVDs) are classified separately as Class A, Class B, Class C and Class D. The classification outcome determines the content requirements of the dossier and the registration route that can be used. This dual-track design is unique in the region and has direct consequences for route selection: the low-risk pathway is open only to listed devices, Class I general devices and Class A IVDs that are also non-sterile, non-active and non-measuring, and the reliance pathway does not extend to Class III. Getting the classification right at the outset is therefore the single decision on which the whole project plan depends.

• General devices are classified Class I, IIa, IIb and III under EU-based classification principles and rules.
• IVDs are classified separately as Class A, B, C and D.
• Classification determines dossier content requirements and the available registration route.
• The low-risk pathway is limited to listed devices, Class I general devices and Class A IVDs, subject to non-sterile, non-active and non-measuring conditions.
• Borderline products can be clarified in advance through the Product Categorization Letter (PCL) procedure.

2. Legal basis

The table below gathers the sources that establish the two classification systems, the factors that determine a device class, the consequences of the class, and the procedure available for confirming classification before a dossier is prepared.

3. Expert insights

Insight 1: this is the only dual-track classification among the ten markets in the series. Malaysia, Indonesia, Vietnam, Thailand, Singapore, the Philippines, India, Bangladesh and Pakistan all use a single letter system, either A to D or I to IV; Sri Lanka is the only market that maintains two separate naming standards, one for general devices and one for IVDs. Chinese-language materials commonly and incorrectly state that Sri Lanka uses four classes A/B/C/D, which is a systematic error. Companies that carry that mistaken assumption into project planning will assign the wrong class names in dossiers and correspondence, which is exactly the kind of inconsistency that generates deficiency questions, so the dual-track structure should be confirmed and communicated to every member of the project team at kickoff.

Insight 2: the class and the route are directly linked. Under GL-037, the low-risk pathway is open only to listed devices, Class I general devices and Class A IVDs, and only when they are at the same time non-sterile, non-active and without a measuring function; Class IIa, IIb and III general devices and Class B, C and D IVDs are entirely excluded from that pathway. In addition, the reliance pathway does not apply to Class III. The practical meaning is that classification is not a labelling exercise: the class decides whether the faster, lighter routes exist at all for the product, and a one-class error at the start of the project either forfeits an available shortcut or claims one that the rules do not permit.

Insight 3: classification can be asked before it is done. NMRA operates a Product Classification Letter (PCL) procedure and also publishes a list of products that NMRA considers not to fall under medical device jurisdiction. Borderline products should have their classification clarified before any dossier preparation investment is made, because the answer determines whether the device track applies, which class applies, and which documents the file will need. Using the PCL procedure converts an internal guess into an official determination and removes the largest single source of rework in borderline projects.

4. Practical recommendations

• Require the project team to answer the three classification questions before work starts: first, whether the product is a general device or an IVD, which decides which of the two classification systems applies.
• Second, if the product is a general device, determine whether it is Class I, Class IIa, Class IIb or Class III under the EU-based principles and rules.
• Third, determine whether the product is sterile, active or has a measuring function, because those three characteristics decide whether the low-risk pathway can be used at all.
• Once the three questions are answered, the route, the dossier and the timeline can all be locked, and the project plan can be built on fixed assumptions instead of provisional ones.
• For any product near the boundary between categories, submit a PCL application before dossier preparation begins, and file the response with the project record.

5. Verification checklist

• □ The two classification systems, general devices and IVDs, have been distinguished.
• □ General devices have been assigned to Class I / IIa / IIb / III.
• □ IVDs have been assigned to Class A / B / C / D.
• □ It has been checked whether the product is sterile, active or has a measuring function.
• □ For borderline products, application for a PCL confirmation has been considered.
