Advertisement Claims and Comparisons under S.I. No. 42 of 2024

1. Key takeaways

Nigeria is one of the few markets that has written advertising vocabulary into legal definitions. Regulation 51 of the interpretation section sets explicit thresholds:

• “Fast” = the claimed effect is observed within 30 minutes;
• “Immediate”/“Instant” = the claimed effect is observed within 10 seconds.

Three companion rules apply: Regulation 41 (claims must be substantiated; absolute statements prohibited), Regulation 42 (false or misleading statements, incomplete truths, vague superiority claims, and “magic”/“miracle” style wording prohibited), and Regulation 43 (factual comparison is permitted but identifiable brands must not be named, and charts must be accurate and show sources).

3. Expert insights

Insight 1: quantifying sensory words is the hardest-edged design in Nigerian advertising regulation.

Most markets rely on general language such as no exaggeration, leaving the judgment to discretion. Nigeria instead gives two numbers — 30 minutes and 10 seconds — turning words like fast and immediate from adjectives into measurable claims. The practical consequence: if you use these words, you must produce performance studies that can prove the stated time threshold. A claim that cannot be tied to a study measuring the effect within the defined window is simply indefensible before the authority, however common the wording may be in other markets.

Insight 2: the four restricted categories in Regulation 41 carry different evidentiary burdens.

Regulation 41 addresses in turn: statements such as safest and guaranteed effectiveness; superlatives must have empirical support; best-selling must not imply product superiority; and fast/immediate/instant/rapid must be supported by performance studies. The strictness differs across the four: the first two are effectively prohibitions, while the latter two can be used once the evidence is supplied. Marketing teams therefore need to know which column a proposed claim falls into before copy is drafted, not after the permit application has been filed and returned.

Insight 3: Regulation 42 prohibits the incomplete truth — which is broader than falsehood.

The scope of Regulation 42 covers false or misleading statements, incomplete truths, vague claims of superiority, and “magic” or “miracle” style wording. An incomplete truth means that presenting only the advantages while hiding material limitations is itself a violation — for example, stressing detection rates without mentioning the false positive rate. The same analysis catches selective quotations of study results, or performance figures quoted without the conditions under which they were obtained.

Insight 4: Regulation 43 gives comparative advertising two workable rules.

Rule one: a factual comparison is allowed, but identifiable brand names must not be indicated. Rule two: where charts or graphs are used for comparison, they must be accurate and must indicate the source. Taken together, the clauses mark out one clearly workable path: speak with data, name no brand, cite the source.

Insight 5: Regulation 35 is the clause foreign companies most easily trip over.

Regulation 35 provides that advertisements must not claim endorsement by a national or international body. Chinese companies often cite a CE certificate or WHO prequalification as a selling point — in Nigeria, if such wording is read as a claim of institutional endorsement, it is a violation. The correct approach is to state facts (for example, that a CE certificate has been obtained) without any implication of endorsement, and to obtain the advertisement permit in advance. The distinction is one of framing: the certificate may be described, but it must not be presented as the institution vouching for the product.

4. Practical recommendations

1. Build a banned-word list for advertising covering fast/immediate/instant/rapid, safest, guaranteed, best-selling, magic and miracle, and run machine screening on all copy.
2. Whenever a quantified time word is used, prepare the supporting performance study in advance and submit it with the advertisement permit application.
3. In comparative advertising, use factual data only, name no brand, and cite chart sources (Regulation 43).
4. Rewrite endorsement-style statements into neutral factual statements (Regulation 35).
5. Review bilingual materials in parallel, so restricted wording is not introduced during translation.
6. Obtain the advertisement permit before any publication, and never substitute the registration certificate (§11.3/§12.3; see article 30).

5. Verification checklist

• □ Advertising copy has passed banned-word screening (Regulations 41 and 42).
• □ Fast/immediate/instant/rapid claims are supported by performance studies (Regulation 51: 30 minutes / 10 seconds).
• □ Comparative advertising names no identifiable brand, and charts are accurate with sources cited (Regulation 43).
• □ No implied claim of endorsement by an institution (Regulation 35).
• □ Bilingual materials have both been reviewed.
• □ The advertisement permit has been obtained and is not substituted by the registration certificate (§11.3/§12.3).
