Biological Safety Evaluation Requirements for Belarus Medical Device Registration

1. Key takeaways

In the preliminary technical work of Belarus, biological safety evaluation is an item triggered by the contact conditions, and the scope of testing is determined jointly by the contact site and the duration of contact. It is an assessment of a nature different from the technical tests, and the two cannot substitute for each other; a full set of technical tests does not remove the biological evaluation requirement.

Because the test scope follows the contact conditions, the same product family can carry very different biological programs across its variants: a surface-contacting configuration and an implantable configuration of one platform rarely share more than the material list. Planning the biological evaluation per configuration, rather than per product family, avoids the most common form of under-scoping found in this kind of file.

3. Expert insights

Insight one: the nature of contact determines the test items; this is the basic logic of biological evaluation. Devices and their accessories that contact the body surface, mucous membranes or the internal environment of the body fall within the scope of biological effect assessment. The longer the contact and the deeper the contact site, the more biological endpoints must be assessed. Before commissioning any test, an enterprise should fix in writing the two parameters of what is contacted and for how long, because every subsequent decision about the test program depends on them.

Insight two: sterility, implantation and long-term contact are three risk amplifiers. The criteria for the risk classification of 1, 2a, 2b and 3 also include invasiveness and contact duration, so the strictness of the biological evaluation usually correlates positively with the risk class. Once the classification is fixed, an enterprise can use it to anticipate the test scope and to plan laboratory capacity ahead of time instead of discovering the requirements after submission.

Insight three: biological evaluation can be completed by a combination of justification and testing; not everything requires a test. Where a material already has a sufficient history of use, material characterization, literature data and existing biological data can be used to reduce or waive part of the testing. This route, however, requires a complete justification file; it is not a simple declaration of exemption, and a thin justification will be treated as no justification at all.

Insight four: testing must be carried out in a qualified laboratory, and the total time limit of 90 calendar days must be taken into account. Biological testing cycles are usually longer than document review, making biological evaluation the item most likely to drag the total time limit in the preliminary technical work. Enterprises should start the tests in parallel with document preparation rather than sending samples only after the dossier is finalized.

Insight five: the evaluation file should record the route taken and the reason for it. Where testing was performed, the file points to the reports; where an endpoint was waived through material characterization and existing data, the file points to the justification. A reviewer who can see, in one summary table, why each endpoint is covered by a test or by an argument, spends less time reconstructing the logic and raises fewer questions. The same table also serves later changes: when a material supplier changes, the table shows in one line which endpoints must be re-examined.

4. Practical recommendations

1. Fix the contact parameters first. Produce a written document stating the contact sites and the maximum contact duration, as the input for the test protocol.
2. Run testing in parallel with document preparation. Do not wait for the registration dossier to be finalized before sending samples, or the tests become the bottleneck of the 90-day total time limit.
3. Make the justification route complete. If relying on material characterization and existing data to reduce testing, provide the full justification file, not a single sentence that the material is widely used.
4. Book laboratory capacity in advance. Qualified laboratories are scheduled tightly, so their availability belongs in the project master plan.

5. Verification checklist

• □ Contact sites and maximum contact duration are stated in writing
• □ Testing has been started in parallel with document preparation
• □ If the justification route is taken, the complete justification file is ready
• □ Laboratory capacity has been included in the project master plan
• □ The test items have been pre-estimated against the list of No. 55

Regulatory information verified as of October 30, 2026.

In the Eurasian Economic Union market, the core capabilities of GRZAN concentrate on three points. First, distinguishing between the two channels of Union-wide registration and national registration in each member state, including their applicable conditions and remaining time windows. The national registration procedure of Belarus has been fully restructured by Council of Ministers Resolution No. 211 of April 28, 2026 (state register number 6-1/55925, effective May 1, 2026), which compressed the total time limit for preliminary technical work to 90 calendar days, applied a closed list that the implementing organization is prohibited from expanding, while applications under the national procedure face the key deadline of December 31, 2027, so pathway selection must be decided in sync with the time window. Second, local authorized representative services, acting as the legal representative of the manufacturer in Belarus, handling registration submission, responses to technical queries, changes to the registration dossier, and post-market reporting obligations; GRZAN has updated its coordination mechanisms after Council of Ministers Resolution No. 378 of July 27, 2026 (effective July 30, 2026) transferred adverse event functions to the state institution Gosfarmnadzor. Third, quality system and testing support, assisting in establishing a quality management system compliant with ISO 13485 and organizing the technical documentation according to the target pathway: for the national pathway, the annex to Ministry of Health Resolution No. 55; for the Union pathway, Decision No. 46 of the Council of the Eurasian Economic Commission.
