On 2 October 2026, Tanzania gave ARIPO trademark registrations designating the country the domestic legal force that most rights holders had assumed they carried since 1999. The Written Laws (Miscellaneous Amendments) Act, 2026, assented to on 19 September and gazetted on 2 October, inserts a new section 28A into the Trade and Service Marks Act and backdates recognition to 1 September 1999, the day the Banjul Protocol entered into force for Tanzania. This is a meaningful repair, but not yet a finished one. At the time of writing, ARIPO has not issued the notice that restores Tanzania as a state applicants can designate.

For those of us building legal infrastructure for cross-border commerce in Africa, the last thirteen months carry a lesson bigger than any single amendment. A regional registration is only as strong as the national law that recognises it, and most rights holders had no practical way to see that gap until a court exposed it.

How Tanzania got here

A confectionery dispute set this in motion. Kenafric Industries, a Kenyan manufacturer, sued its former Tanzanian distributor, Lakairo Industries, for infringing three marks it held through Kenyan and ARIPO registrations. Kenafric succeeded at first instance in the High Court's Commercial Division. On 26 September 2025, the Court of Appeal reversed that outcome in full (Civil Appeal No. 593 of 2022).

The reasoning rested on Tanzania's dualist constitutional design: a treaty binds domestic courts only once Parliament writes it into national law. Tanzania had acceded to the Banjul Protocol but never incorporated it into the Trade and Service Marks Act. ARIPO marks designating Tanzania therefore conferred no enforceable rights there, and Lakairo's national registrations stood.
Three administrative shocks followed:
•      ARIPO suspended Tanzania. On 23 October 2025, acting on instructions from the Business Registrations and Licensing Agency (BRELA), ARIPO declared Tanzania ineligible for designation under the Banjul Protocol until further notice (ARIPO notice).
•      Border enforcement tightened. From 1 December 2025, every trademark on goods imported into mainland Tanzania had to be recorded with the Fair Competition Commission (FCC) under section 11A of the Merchandise Marks Act and the Merchandise Marks (Recordation) Regulations, 2025. Unrecorded goods risk detention at the port.
•      The FCC narrowed, then widened, its door. In early 2026 the FCC limited recordation to fully registered national marks and refused ARIPO and foreign certificates. Later guidance, reported by practitioners between April and September 2026, allowed those certificates to support recordation, while making clear they do not themselves create enforceable rights.
The net effect was a squeeze. Brand owners who had relied on ARIPO could not sue on their registrations and, for a period, could not use them to clear goods at the border either.

The legislative fix took 53 weeks from judgment to commencement; most of that was the eight months between the Bill and assent.

What the 2026 Amendments change

The Act does two jobs at once: it repairs the ARIPO gap, and it modernises a trade mark statute that dates from 1986.
Change
What it does
Why it matters
ARIPO trademarks (new s28A)
Deems Banjul Protocol registrations designating Tanzania to be registered under domestic law, back to 1 September 1999, unless the Registrar told ARIPO a mark would have no effect
Historic ARIPO portfolios regain a statutory basis for enforcement
ARIPO patents and designs
Extends equivalent recognition to Harare Protocol rights designating Tanzania
Removes long-standing doubt over ARIPO design rights in particular
Definition of a mark
Drops the "visible sign" test; signs now include 3D shapes, colours, get-ups and holograms
Brand elements that were hard to register become protectable
Collective and certification marks
Introduced expressly for the first time
Gives cooperatives, industry bodies and standards organisations a dedicated route
Well-known marks
Statutory test for well-known status; injunctions available against confusing use even without local registration
Reputation-based protection for international brands, subject to evidence
Early advertisement
Registrar may advertise an application before acceptance in exceptional circumstances
Conflicts may surface earlier; "exceptional" is undefined
The ARIPO provision carries the most commercial weight. Without it, every ARIPO-only portfolio covering Tanzania would have needed rebuilding, mark by mark, through national filings.

What remains unresolved

The statute is in force, but six practical questions will decide how much certainty it actually delivers.
1.     Designation is not yet restored. In early October, ARIPO advised it was consulting with the Tanzanian registry and would issue an official notice once those talks concluded. We have found no such notice published as at 26 October 2026. Until it appears, new ARIPO filings cannot cover Tanzania.
2.     Collisions with rights acquired in the gap. The Act does not say how backdated ARIPO rights rank against national registrations obtained while ARIPO marks were unenforceable. Lakairo itself is the template: a local party holding national registrations for marks a foreign owner held through ARIPO. Expect these conflicts to be litigated.
3.     The refusal carve-out. Recognition does not extend to marks where the Registrar notified ARIPO that the mark would have no effect in Tanzania. Every rights holder now needs the file history of each designation, not just the registration certificate.
4.     Which date counts. There is an open question of whether priority runs from the ARIPO filing date, the ARIPO registration date or commencement of the amendment. That choice could decide contested cases.
5.     Border recordation. Whether the FCC will now treat ARIPO registrations as equivalent to national ones for recordation and enforcement is not yet settled.
6.     Zanzibar. The amendment touches the mainland statute only. Zanzibar runs its own system under the Zanzibar Industrial Property Act, 2008, administered by its Business and Property Registration Agency, and the FCC recordation regime also applies to the mainland only.

The continental lesson: ratification is not enforcement

Tanzania is the clearest case of a wider African pattern, regional rights can be valid on a regional register yet unenforceable before a national court. The Banjul Protocol lists 13 contracting states in ARIPO's 2026 edition, and ARIPO itself has acknowledged user concerns about enforceability in states that have not expressly domesticated it. Tanzania was not unique in its legal structure; it was unique in having that structure tested at its highest court.
The same test is coming at continental scale. The AfCFTA Protocol on Intellectual Property Rights was adopted in February 2023, and AU heads of state adopted its eight Annexes in February 2026. It enters into force only after 22 ratifications. After that, each dualist state party will still need national legislation before its courts apply the Protocol's standards.
The encouraging signal is speed. Tanzania moved from adverse judgment to gazetted fix in just over a year. When governments see the commercial cost of a gap, they can close it. The harder task is spotting gaps before a court does.

Why this is a legal infrastructure problem

The Tanzania episode was an information failure as much as a legal one. For more than two decades, portfolio records could show a mark as "registered" in Tanzania while saying nothing about whether a Tanzanian court would enforce it.
In African IP, "protected" is not one status. It is at least four layers that move independently:
•      Registry status: is the right on the regional or national register?
•      Domestic recognition: has the national statute given that right legal effect?
•      Border status: is the mark recorded with the customs or competition authority where recordation is mandatory?
•      Territorial reach: does the right extend to semi-autonomous territories such as Zanzibar?

In Tanzania, all four layers shifted within thirteen months, and the FCC's position alone moved more than once. No spreadsheet maintained by a brand owner in Dubai, Johannesburg or Shanghai reliably tracks that. Neither does a single law firm acting in one jurisdiction.

This is the gap AfricanLaw is built to close. Cross-border legal work in Africa needs a coordination layer that maps rights to enforceability, watches gazettes and registry notices for change, and routes action to verified local practitioners who can act on the ground. Technology will not replace the Tanzanian practitioner who reads the gazetted text. It should ensure that the practitioner's reading reaches every affected portfolio within days, not after a court case.

What rights holders should do now

Treat the next quarter as an audit window, not a reason to relax.
1.     Inventory every ARIPO designation of Tanzania across trademarks, patents and designs, including lapsed and pending files.
2.     Pull the file history for each one to confirm the Registrar did not notify ARIPO of a refusal, which would exclude it from section 28A.
3.     Search the national register for conflicts filed while ARIPO marks were unenforceable, and assess whether to oppose, negotiate or prepare for litigation.
4.     Keep filing nationally for new marks in mainland Tanzania until ARIPO publishes its notice restoring designation.
5.     Confirm FCC recordation for every mark on imported goods and keep national certificates on file where they exist.
6.     File separately in Zanzibar wherever goods or services reach the islands.
7.     Revisit what is now registrable: shapes, colours, get-ups and holograms, plus collective or certification marks for associations and standards bodies.
8.     Build a well-known mark evidence file covering recognition, duration and reach of use, promotion, registrations and enforcement history.
