Seed Dealers in Tanzania: TOSCI Certification, Not a Fertiliser Licence
Is a fertiliser dealer licence enough to sell certified seed in Tanzania? No. Dealing in certified seed is a Tanzania Official Seed Certification Institute file under the Seeds Act, Cap. 308: certification of the seed itself, and dealer or agro-dealer registration as the live TOSCI and district rules name. Variety release, seed-class (breeder, foundation, certified), and a shop licence are different papers. TMDA does not cover seed. TFRA does not cover seed. Confirm tosci.go.tz.
This page is the TOSCI seed-dealer file. It is not a TFRA fertiliser walkthrough, not a TMDA registration, and not a crop-buying licence.
- Fertiliser dealers: TFRA, not TOSCI
- Cashew crop board: a different crop, a different board
As at 10 September 2026. Confirm tosci.go.tz. Zanzibar seed is a different administration.
Certification of the lot, then the dealer
| Instrument | What it is | What it is not |
|---|---|---|
| Variety release / national list | This variety may be sold as seed | Permission for you to retail it |
| Seed class (breeder / foundation / certified as live-named) | The generation and the standard the lot met | A shop licence |
| TOSCI dealer / producer / importer registration | You may deal in certified seed from named premises | A TFRA fertiliser class |
| District agro-dealer overlays | As local rules still name them | A substitute for TOSCI |
Uncertified grain sold as “seed” is how farmers lose a season and how TOSCI inspections start. Keep lot identity, labels, and the certification documents that travelled with the bags. Rebagging certified seed into unmarked sacks is the failure mode, not a margin strategy.
Importers still need the live TOSCI import and quarantine path, plus plant-health instruments the Tanzania Plant Health and Pesticides Authority (or the live successor name) administers. TOSCI certification is not a phytosanitary certificate. Do not collapse those desks because both sit in agriculture.
Sequence
- Name the crop, the variety, and whether you produce, import, or only retail.
- Confirm the variety is on the live list. Do not import a variety that is not releasable.
- Form the company. Take TOSCI dealer (and producer, if you produce) registration.
- If you import, take the import and plant-health instruments consignment by consignment as required.
- Keep lot documents with the bags. Sell only labelled certified seed.
- If you also sell fertiliser, open TFRA. If you also buy crop at the farm gate, screen GN 487A.
Worked path: the agro-dealer who poured seed into smaller bags
A licensed dealer splits 50 kg certified bags into 2 kg unlabelled piles because smallholders ask for “just a little.” The certification travelled with the original bag. The piles are now uncertified. Stop, or pack only in labelled units the live rules allow. A different stall: a seed company treats TFRA product registration as covering a maize hybrid. Fertiliser and seed are different statutes.
Germination printed on the label is a claim TOSCI can test
Certified seed carries a labelled germination and purity the lot met at certification. Selling last season’s bags without checking remaining life is how a district complaint starts. Keep lot numbers. Keep the certificates. If the live rules require retesting after a period, confirm that period. This page will not freeze it. Counterfeit hybrid maize is a known East African failure mode. Buy from the person TOSCI actually registered, not from a pickup at the roadside.
Producer versus dealer
Producing certified seed (isolation distances, inspections, processing plant) is a heavier TOSCI file than retailing sealed bags. Do not file as a dealer and then run a production farm. Importers who relabel foreign bags as “certified in Tanzania” without the live TOSCI path are not importers. They are a seizure. Plant-health (TPHPA) still sits on the consignment. Two desks, two stamps.

Frequently asked questions
Does TFRA cover seed?
No. TOSCI certifies seed.
Is grain the same as seed?
Not if you sell it as seed. Certified lots carry documents.
Can I rebag certified seed?
Not into unlabelled piles. Confirm the live packing rules.
Import?
TOSCI plus plant-health instruments. A dealer class is not an import permit.
Fees?
Not published here. Confirm TOSCI. Zatra’s fee is only on /pricing/.
