Tanzania Medical Device Assessment Timeline: Stage by Stage Working Day Limits

1. Key takeaways

Tanzania is one of the few African markets that writes assessment timelines into official guidance stage by stage and class by class. Part I §3.4.4 through §3.4.8 of the June 2024 Compendium gives the complete numbers:

2. Legal basis

3. Expert insights

Insight 1: The official numbers contain one typographical error, which must be corrected when citing.

The original text of Part I §3.4.5 reads: “The assessment stage is expected to take 23 working days for class A and B devices and 40 working days for class A and B devices”. The second “class A and B” is evidently meant to be class C and D — otherwise the two halves contradict each other. GRZAN reads the C/D figure as 40 working days in external documents, while noting that the figure comes from the official text with a typographical slip, and recommends obtaining written confirmation from TMDA. This is an official text defect, not something an applicant can correct on TMDA’s behalf, but it must be explained clearly to clients so no one later accuses the file of misquoting the guidance.

Insight 2: The authority states expressly that the timelines exclude site inspections.

The note to §3.4.5 reads: “Quality Audit of the manufacturing facilities is also incorporated into the assessment process however, the timelines reflected above do not include the time for conducting site inspections.” This is the single most important practical message in this article: for Classes C and D that trigger a site audit, the 93 working days cover only the document review; the scheduling and execution of the site audit run as an independent period layered on top. Treating 93 working days as a delivery date is the most common planning error in Tanzanian projects. Companies should request the audit availability early, align travel and interpretation resources, and treat any auditor rescheduling as a formal milestone change in the project plan rather than a minor administrative slip.

Insight 3: Notification undergoes first assessment only, with 5 working days of processing.

§3.4.8: “Applications for notification shall only undergo first assessment. The time frame for processing of notification is 5 working days.” This stands in sharp contrast to the dual assessment for registration, and it is the most tangible value of the notification route — not saving dossier work, but saving review layers. For qualifying Class A products, that difference in review depth is what makes the channel commercially meaningful, particularly for consumables with short commercial windows or tender-driven demand cycles where every week of delay carries a direct revenue cost.

Insight 4: 43 and 93 working days are baselines only; a query halts the clock indefinitely.

§3.4.6 provides that once a query is raised, the processing shall halt until the response is received. The official numbers therefore contain no query round-trips at all. The industry claim that Tanzanian registration takes 4–6 months, extending to 9 months for high-risk devices, has not been verified against any official source; handle it as a practical estimate and do not present it as an authority figure.

Insight 5: The scheduling stage itself carries elasticity.

Before giving its numeric caps, §3.4.4 states that the time taken to schedule assessment depends on the complexity of the device and the availability of assessors. The 10 and 20 working days are ceilings, not commitments. Projects with unusual device technologies or assessor scarcity should expect scheduling to consume the full allowance, and should not promise clients the average of the range.

4. Practical recommendations

1. Quote and schedule externally using the document-review baseline: approximately 43 working days for Classes A/B and approximately 93 working days for Classes C/D, expressly excluding query round-trips and site inspections.
2. Schedule site audits for C/D projects as a standalone sub-project, never folded into the 93 working days.
3. Turn query response speed into an internal SLA. The 60-working-day deemed withdrawal rule in §3.4.6 is a hard constraint (see article 09).
4. Plan notification projects on 5 working days plus 1–2 working days of screening, but remember that samples and payment still sit in front of the clock.

5. Verification checklist

• □ The review baselines have been confirmed by risk class: 43 working days for A/B, 93 working days for C/D, 5 working days for notification.
• □ The baseline has been confirmed to exclude query round-trips and site inspections.
• □ The typographical error in official §3.4.5 has been explained to the client or internally (C/D is 40 working days).
• □ A separate site-audit schedule has been set for C/D projects.
• □ The scheduling caps of 10 / 20 working days have been treated as ceilings, not commitments.
