Grouping Multiple Change Applications in Tanzania

1. Key takeaways

Tanzania permits several changes to be combined into one application, but the rules tighten layer by layer. TMDA/DMD/MDA/G/003 §6.1 organises the possibilities as follows.

The 4 categories of §6.1.3: a) a change of the product applicant/marketing authorisation holder; b) a change of manufacturing and/or sterilisation site; c) a change involving only the update of the validity of the QMS certificate; d) the addition of an identical Class A accessory.

The architecture is deliberately restrictive: consolidation is a cost-saving tool for administrative content, not a general bundling mechanism. Anything that touches the technical substance of the product is expected to stand on its own application, and misjudging this boundary can cost an entire submission rather than just a fee surcharge.

3. Expert insights

Insight 1: The highest-category charging rule of §6.1.1 is a cost-control rule.

Where one submission contains a major change together with minor and notifiable changes, fees and assessment are charged at the highest category present, namely major. This means that bundling several minor or notifiable changes with one major change prices the cheap changes at the major rate as well. Conversely, separating the major change into its own application and submitting the remainder as minor or notifiable changes is more cost-efficient. GRZAN’s practice is to calculate the classification first and only then decide whether consolidation pays.

Insight 2: The rule that non-identical changes cause the entire application to be unaccepted is the harshest provision in the section.

The original text reads: “Non-identical changes in any one listing may result in the entire application for changes being unaccepted.” Note the word entire. Stuffing twenty products with twenty different changes into one application in the name of efficiency means that a single non-identical item can sink the whole submission. This is a high-penalty rule, and the identical nature of each change must be verified line by line before filing.

Insight 3: §6.1.2 opens only two doors: identical administrative changes and adding the same new product to several registrations.

Beyond these, §6.1.2(c) provides that non-identical changes not falling into the listed categories must be submitted as separate applications for each change. The consolidation space in Tanzania is therefore genuinely narrow – what can be combined is essentially administrative content, such as contact details or certificate updates, and technical changes must be filed individually even where they are conceptually similar.

Insight 4: §6.1.3 compresses cross-risk-class consolidation to 4 categories, two of which concern system documentation.

Of the 4 categories, holder changes (a) and site changes (b) belong to the certificate-information type, while the QMS certificate validity update (c) and the addition of an identical Class A accessory (d) belong to the low-risk supplementation type. What the four share is that none of them changes the technical content of the product. Any change involving technical content cannot be consolidated across risk classes, whatever its apparent similarity.

Insight 5: Consolidated applications and recall-triggered changes follow different procedures.

§6.2 requires recall-triggered changes to be brought to TMDA’s attention before submission, while the consolidation rules of §6.1 carry no such pre-step. Where both apply to the same submission – for example a consolidated application that includes a recall-triggered change – the stricter procedure prevails, so the pre-submission contact must be made even though the application as a whole was filed under §6.1.

4. Practical recommendations

1. Calculate the classification before deciding to consolidate – under §6.1.1 the highest category governs the fee, so bundling does not always save money.
2. Define identical administrative changes strictly: changes across products must be literally identical; one mixed item endangers the whole application (§6.1.2(a)).
3. Submit technical changes per product; do not force them into a consolidated application (§6.1.2(c)).
4. Use only the 4 consolidation channels across risk classes (§6.1.3): holder change, site change, QMS validity update, addition of an identical Class A accessory.
5. For changes to the same device within a family/system/group/kit, confirm that the selected implementation products are identical (§6.1.2(b)).
6. Where a consolidated application contains a recall-triggered change, contact TMDA first (§6.2).

5. Verification checklist

• □ The fee category of the consolidated application has been calculated under §6.1.1 (highest category governs).
• □ Multi-product consolidation has been confirmed as an identical administrative change or an addition of the same new product (§6.1.2(a)).
• □ No non-identical change has been mixed into any listing (avoiding the entire application being unaccepted).
• □ For changes within a family/system/group/kit, the implementation products have been confirmed as identical (§6.1.2(b)).
• □ Cross-risk-class consolidation falls within one of the 4 categories (§6.1.3).
• □ Where recall-triggered changes are included, TMDA was contacted before submission (§6.2).
