Common Causes of Registration Refusal and How to Prevent Them

1. Key takeaways

Nigeria writes the grounds for refusal of registration into Regulation 4(10), with four items:

• (a) the methods, facilities or controls used for the manufacture, processing or packing of the device are inadequate to preserve its quality and characteristics;
• (b) the laboratory report is unsatisfactory;
• (c) the GMP inspection report is unsatisfactory;
• (d) the labelling contravenes the provisions of the Regulations.

In addition, Regulation 4(11) points to other requirements. Three of the four grounds (a, b, c) are controllable before submission, and (d) is purely a documentation matter — which means the overwhelming majority of refusals are preventable.

3. Expert insights

Insight 1: the four grounds map exactly onto four stages of the registration process.

The four items of Regulation 4(10) correspond one to one to the process: (a) manufacturing controls to the GMP stage; (b) laboratory report to the testing stage; (c) GMP inspection report to the site stage; (d) labelling to the documentation stage. Treat them as four internal gates in a pre-submission review, and the refusal rate will fall markedly.

Insight 2: dossier quality is itself a hidden rejection point.

VBM-R&RA-GDL-005-01 states expressly that a non-compliant dossier may be rejected without review, and that submitted dossiers are destroyed and not returned. This differs from Regulation 4(10): it is not a rejection after review but a rejection before anyone looks, and the originals cannot be recovered. A complete copy set must therefore be archived before submission.

Insight 3: ground (d), labelling violations, is the most regrettable and the most common cause of refusal.

Labelling problems involve no technical capability; they are pure cross-checking work. The labelling elements listed across articles 23–25 and 26–27 (product identification, expiry date, batch number not pre-printed, manufacturer and holder name and address, ingredients, storage conditions, NAFDAC registration number, instructions for use, warnings, net content) can be avoided by item-by-item comparison alone. Make the compliance review of label proofs a standalone process step, never merged into document drafting.

Insight 4: an unsatisfactory laboratory report often stems from the sample, not the testing.

The common failure points in the laboratory stage are not testing capability but sample condition: NAFDAC laboratory rejection situations include broken cold chain, insufficient quantity, missing documents, unclear labelling, product-document mismatch, and remaining shelf life of less than 6 months. All of these can be eliminated before shipment, and none of them requires technical input beyond a disciplined dispatch checklist.

Insight 5: refusal and compliance queries are two different tracks with different consequences.

Regulation 4(10) is a refusal; at the guideline level there are also compliance queries (query/compliances) — the latter stop the clock (§11.8/§12.8), and if unanswered for 90 days / 90 working days the application closes automatically (§11.6/§12.6). A compliance query is remediable; a refusal is final for the current application round. The speed of your response to compliance queries therefore decides the project. A query answered quickly converts into review progress; a query answered late converts into a closed file and a fresh application, with all fees and effort repeated.

4. Practical recommendations

1. Use the four items of Regulation 4(10) as a checklist for internal pre-review, issuing a pass or rework conclusion for each item.
2. Archive a complete copy of the dossier, because a non-compliant dossier may be destroyed and not returned.
3. Set up a standalone compliance review step for label proofs, never merged with document drafting.
4. Self-check the six laboratory rejection situations before shipping samples, especially remaining shelf life of at least 6 months and cold chain integrity.
5. Set an internal response deadline of 30 days for compliance queries, far ahead of the official 90 days / 90 working days red line.
6. Rehearse the GMP site inspection against DER-GDL-025-00 clause by clause, focusing on nonconforming product control, CAPA, and recall and complaint records.

5. Verification checklist

• □ Internal pre-review completed against the four grounds of Regulation 4(10) (manufacturing controls / laboratory report / GMP report / labelling).
• □ A complete dossier copy has been archived (originals may be destroyed and not returned).
• □ Label proofs have passed the standalone compliance review step.
• □ The six laboratory rejection situations have been eliminated before sample shipment (including remaining shelf life of at least 6 months).
• □ The internal response deadline for compliance queries is set at 30 days (ahead of the 90 days / 90 working days red line).
• □ The GMP site inspection has been rehearsed against DER-GDL-025-00.
