Sri Lanka STED Summary Technical Documentation Explained

1. Key takeaways

The STED (Summary Technical Documentation) is the technical core of the Sri Lankan PRD dossier, and the authorities explicitly require it to be prepared according to the GHTF specification. Accompanying it is the Essential Principles Checklist, which is likewise marked as following the GHTF specification. Together, the two documents answer two questions: what the product is, and on what basis it is considered safe and effective. The STED carries the technical description — design, manufacturing, verification and validation evidence in summary form — while the Essential Principles Checklist demonstrates compliance point by point against the applicable general safety and performance requirements. Neither document can substitute for the other, and both must be present in the PRD section of the dossier. For manufacturers with experience in GHTF-aligned markets, this pairing will be immediately recognisable, and the good news is that the structural work largely transfers from those markets. For manufacturers encountering this framework for the first time, the pairing defines the two deliverables that deserve the earliest and most careful attention during dossier planning.

• The STED is explicitly required to follow the GHTF specification and sits at the technical centre of the PRD.
• The Essential Principles Checklist follows the same GHTF specification and operates in tandem with the STED.
• The two documents together answer two questions: what the product is, and why it is safe and effective.
• General devices are classified under the classification principles and rules of the European Union Medical Device Regulation.
• Technical evaluation is performed by MDEC, which meets monthly.

2. Legal basis

The table below consolidates the regulatory anchors for the STED and its companion documents. The dossier-level requirements derive from GL-034, which took effect on 2025-07-23, while the classification principles for general devices derive from GL-037, which took effect on 2026-05-13. The assessment body reference comes from the NMRA website. Three points in this table deserve attention. First, the STED and the Essential Principles Checklist share the same specification basis, which is why they should be drafted together rather than by separate teams working in isolation. Second, the distinction between general devices and IVDs matters here: the STED requirement discussed in this article applies to products that fall within the device definition but outside the IVD category, and IVD dossiers follow their own supplementary requirements. Third, because general devices follow the classification principles and rules of the European Union Medical Device Regulation, the risk class determined under those rules drives how much technical depth the STED is expected to carry.

3. Expert insights

Insight one: the STED is a summary, not the full set of raw data. Its role is to present the technical documentation in summary form, and this reduces the volume of documents submitted at first filing. The flip side is that the demands on the accuracy and internal consistency of the summary are higher. Every statement in the STED should be traceable to underlying records held by the manufacturer, because assessors may ask for justification of any summary-level claim. A summary that contradicts the underlying test reports or the Essential Principles Checklist creates more problems than a longer but coherent submission would have, since the reviewer will treat the contradiction as a signal of weak document control overall.

Insight two: the STED and the Essential Principles Checklist are a paired set. The former describes how the product is designed, manufactured, and verified; the latter reconciles, item by item, which essential principles are met and by which evidence. The consistency between the two documents is where assessment most easily uncovers problems. If the checklist cites a section that does not exist in the STED, or if the STED describes a verification activity that the checklist never references, the reviewer will flag the mismatch. Cross-checking the two documents before submission should therefore be treated as a mandatory internal step, not a formality. A practical way to enforce this is to have one person own both documents and to freeze the section numbering of the STED before the checklist is drafted, so that citations remain stable.

Insight three: the GHTF framework creates room for cross-market reuse. For companies that have already prepared submissions under GHTF or IMDRF templates for other countries, the main sections of the STED can be reused directly, with adaptation only for the Sri Lankan localisation requirements (language, labels, and MAH information). This materially shortens preparation time compared with building the documentation from zero, and it also reduces the risk of internal inconsistencies, because the reused sections have typically already survived review in another market.

4. Practical recommendations

• GRZAN’s approach to compiling the STED is one base, multiple versions: establish a single underlying technical documentation set organised by the GHTF section structure, then generate market-specific versions from it according to each market’s requirements.
• For Sri Lanka, the adaptation list includes: main text in English, trilingual labels and patient information leaflet, the MAH name and address, and evidence of approval by reference countries.
• Maintain version numbers and dates uniformly across the base documentation and the Sri Lankan version, so that every derived document points back to the same controlled source.
• Before submission, cross-check every Essential Principles Checklist entry against the corresponding STED section to confirm that citations resolve correctly.

5. Verification checklist

• □ STED compiled according to the GHTF section structure
• □ STED content consistent with the Essential Principles Checklist
• □ Localisation adaptation completed to Sri Lankan requirements
• □ Reference country approval evidence attached
• □ Version numbers and dates unified across the dossier
