WITHDRAWAL OF 675 OF THE FORMULATED PRODUCTS WHOSE REGISTRATION HAVE NOT BEEN RENEWED OVER THE PAST TEN YEARS

The Tanzania Plant Health and Pesticides Authority (TPHPA) has announced the withdrawal of 675 formulated pesticide products whose registrations have not been renewed for over ten years. This significant regulatory action, effective January 8, 2026, is part of a broader initiative to enhance plant health, safeguard human health, and protect the environment by removing unauthorized and potentially hazardous agricultural inputs from the market. The move underscores Tanzania's commitment to strengthening its pesticide regulatory framework, aligning with international standards, and addressing historical lapses in compliance, with implications for manufacturers, distributors, and agricultural practitioners across the country.

The agricultural sector in Tanzania is currently undergoing a significant regulatory overhaul following a directive from the Tanzania Plant Health and Pesticides Authority (TPHPA). On January 8, 2026, the TPHPA issued a public notice announcing the withdrawal of 675 formulated pesticide products from the market. This decisive action targets products whose registrations have not been renewed over the past decade, effectively deeming them obsolete and unauthorized for use.

This withdrawal is not an isolated event but forms a critical component of a larger regulatory push by the TPHPA to enhance the safety and integrity of agricultural inputs. Coupled with the simultaneous withdrawal of 130 Highly Hazardous Pesticides (HHPs), the Authority has removed over 800 pesticide products, signaling a robust commitment to aligning Tanzania's plant health and pesticide control measures with international best practices. For legal practitioners, particularly those advising agricultural businesses, importers, and manufacturers, understanding the legal basis, implications, and compliance requirements of this directive is paramount to navigating the evolving regulatory landscape and mitigating potential liabilities.

The regulatory framework governing plant health and pesticides in Tanzania is primarily enshrined in the Plant Health Act No. 4 of 2020 (Cap. 133). This Act established the Tanzania Plant Health and Pesticides Authority (TPHPA) as the national plant protection organization, consolidating previous functions of the Plant Health Services and the Tropical Pesticides Research Institute. The TPHPA is mandated to prevent the introduction, establishment, and spread of pests, facilitate safe trade, and regulate pesticides to safeguard agricultural productivity, human health, and the environment.

Under the Plant Health Act and its accompanying regulations, including the Plant Health Regulations of 2023 (with amendments of 2024), all pesticides intended for commercial purposes, importation, manufacture, or formulation must be registered with the TPHPA. A full pesticide registration typically expires after five years, necessitating a timely renewal process to maintain legal authorization for market circulation. The failure to renew a product's registration for an extended period, such as ten years, signifies a lapse in regulatory compliance and raises concerns about the product's continued relevance, safety, and efficacy, leading to its classification as obsolete.

The TPHPA's decision to withdraw 675 formulated products due to non-renewal of registration for over a decade highlights a critical enforcement of existing regulatory provisions. The Director General of TPHPA, Prof. Joseph Ndunguru, explained that such products are considered obsolete, as the prolonged lapse in renewal suggests that their owners no longer possess a legitimate commercial or agricultural justification for their presence in the market. This action is a direct consequence of the TPHPA's comprehensive review of all registered pesticides, which also identified 130 products as Highly Hazardous Pesticides (HHPs) based on FAO/WHO criteria.

The legal basis for this withdrawal is firmly rooted in the TPHPA's mandate under the Plant Health Act, 2020, which prohibits the use of unregistered pesticides and empowers the Authority to regulate and control these substances. While the Act and its regulations outline procedures for registration and renewal, the widespread circulation of products without valid registration points to historical challenges in market surveillance and enforcement capacity within Tanzania. The current withdrawal aims to close this 'shadow market' by removing the legal justification for these products.

Practitioners should note the grace period of up to two years granted to dealers with existing stocks of the withdrawn products, allowing them to exhaust their supplies under close regulatory supervision. This provision aims to mitigate abrupt disruptions in the agricultural sector while ensuring a phased transition to compliant products. The TPHPA's proactive stance is also influencing neighboring countries, with Uganda, Rwanda, and Zambia reportedly reviewing their pesticide registration standards in response to Tanzania's stricter approach, indicating a potential regional shift towards enhanced pesticide regulation.

The withdrawal of 675 formulated pesticide products by the TPHPA marks a pivotal moment in Tanzania's commitment to robust agricultural regulation and public health protection. For legal professionals, this action necessitates a thorough review of clients' pesticide portfolios to ensure full compliance with the Plant Health Act, 2020, and its subsidiary regulations. Companies involved in the importation, manufacture, distribution, or sale of pesticides must verify the current registration status of all their products and initiate renewal processes promptly where applicable.

Looking ahead, practitioners should advise clients to proactively engage with the TPHPA and monitor official announcements for updated lists of approved pesticides and any further guidance on compliance. The Authority's ongoing inspections of fumigation service providers and its broader efforts to align with international standards suggest a sustained period of heightened regulatory scrutiny. Ensuring adherence to these evolving standards is crucial not only for legal compliance but also for maintaining market access and contributing to a safer, more sustainable agricultural sector in Tanzania.
