You Cannot Trademark Your Perfume. Here Is What Tanzania’s Scent Businesses Can Protect Instead

The Play-Doh Problem

In 2018, Hasbro registered the smell of Play-Doh as a trademark in the United States. The USPTO description says: “a sweet, slightly musky, vanilla fragrance, with slight overtones of cherry, combined with the smell of a salted, wheat-based dough.” After years of consumer association, one company now legally owns a scent.

There are fewer than twenty active scent trademarks worldwide. This is not because the law forbids them, but because getting one is extremely difficult, especially in Tanzania.

Tanzania’s Fragrance Market Is Worth Protecting

Tanzania’s perfume market grew by 37 per cent in 2023, reaching USD 2.3 million. It is expected to reach USD 540 million by 2028. From Dar es Salaam’s boutique perfumeries to Arusha’s candle makers and the East African trade routes carrying Tanzanian attar and bakhoor, the industry is expanding quickly. As the market grows, so does competition. Unique fragrances can be copied, and signature scents can be replicated. Competitors who did not create the original scent can undermine brands built around smell.

The obvious question is: can you protect it? Under Tanzanian law, the answer is yes in theory, but almost never in practice.

What the Law Actually Says

Tanzania’s Trade and Service Marks Act, administered by BRELA, recognizes non-conventional marks including sounds and scents. Zanzibar’s trademark regulations go further, naming scents explicitly as a registrable category. On paper, this is real progress. Tanzania’s legal framework has formally acknowledged that a smell can function as a brand identifier.

However, recognizing the possibility and making registration possible are not the same. Since January 2026, the Fair Competition Commission has strengthened BRELA’s authority. Now, trademarks must be registered nationally through BRELA. International and ARIPO registrations are no longer enough for local enforcement. It is more important than ever to know your rights.

The Functionality Doctrine and Why It Kills Most Applications

Trademark law follows the functionality doctrine. This rule means that if a product’s scent is its main feature, or if fragrance is the reason the product exists, no company can claim it as a trademark. Perfume is meant to smell good, so its scent cannot be owned. Allowing a single business to trademark it would grant them a permanent monopoly on a basic product feature, which is not what trademark law is for.

This is not a loophole in the law. It is intentional.

What it means for Tanzania’s scent businesses:

• Perfumers and cologne brands. The fragrance is the product. Registration is almost certainly unavailable.
• Scented candles and room diffusers. The scent is the point. The same barrier applies.
• Bakhoor and incense producers. Inherently scented goods face the highest resistance.
• Body oils and attars. Unless the scent is entirely unrelated to the oil’s function, expect a refusal.

The Exception: When Scent Trademarks Work

The few registered scent marks worldwide, like a rose scent on vehicle tyres in the UK, a bitter beer scent on dart flights until 2034, Play-Doh’s vanilla-musk in the USA, and fresh-cut grass on tennis balls in the EU, all share one thing: the scent is unrelated to the product’s function. It is simply a brand signal.

This creates a small but real opportunity for some Tanzanian businesses:

• A fashion boutique running the same signature diffuser scent across all its outlets
• A hotel group with a consistent, custom-blended lobby fragrance across properties
• A gym or wellness brand with a proprietary scent environment
• A vehicle dealership with a branded showroom scent

In these examples, the scent is not the product’s function. Instead, it shapes how people experience the brand. This difference can determine whether an application is accepted or rejected.

The Tanzania-Specific Obstacles

Even for businesses that pass the functionality test, registration in Tanzania carries specific challenges.

So far, there are no scent trademark registrations through BRELA on mainland Tanzania. Any new application will be breaking new ground, with no local examples or established process to follow. Applicants must provide a written description of the scent that is sufficiently precise for legal purposes, along with a physical sample. Describing a fragrance in a way that meets legal standards is much harder than it seems.

Besides registration, applicants must show that consumers already connect the scent to their brand, not just that they use it. Building this evidence takes time, careful documentation, and planning. For most small and medium businesses, this is a big investment before applying.

What This Means Depending on Where You Sit

If your business sells fragrance as the main product, trademarking the scent is not the right approach. Instead, trademark your brand name, logo, and packaging through BRELA, where protection is clear and enforceable. Keep your formulas as trade secrets and use confidentiality agreements with suppliers, partners, and distributors. Build your brand’s value through your name and visual identity. These are what you can register and what will protect your business.

If your business uses scent as part of the customer experience, you might have a valid case, but you will need evidence you may not have started gathering yet. Record your scent’s consistent use across locations and over time. Run consumer surveys to test brand association. Make your scent a planned, documented part of your brand strategy, not just an extra detail. Gather evidence before you apply, because applications without proof will be rejected.

The Deeper Lesson

The Play-Doh trademark worked because of years of consistent use, strong consumer association, and solid evidence. Hasbro did not just decide one day to register a smell. They built up the asset over time and then protected it.

Tanzania’s most successful brands will handle intellectual property in the same way. Treat registration as the final step, not the first. Build and document your scent, name, logo, and visual identity as a consistent brand asset from the start. This is what will be best protected.

Tanzania’s scent market is expanding. The businesses that succeed will be those that know what they can legally protect and build everything else on that foundation.

One Final Thought

The functionality doctrine is not a problem for Tanzania’s scent industry. It helps clarify what can and cannot be owned. A fragrance that cannot be trademarked can still support a brand that is trademarked, like a name, logo, or visual identity that is registered and protected. The scent creates the experience, while the trademark protects the brand.
