Bolts & nuts in Tanzania
What actually moves in this market.
Tanzanian mining maintenance is the demanding end of this market. Teams order against a shutdown bill of materials, not a drawing, and the date is fixed — a bolt that arrives the week after the shutdown is worth nothing. We schedule production and freight backwards from the shutdown window.
Steel fabricators around Dar es Salaam and Arusha buy grade 8.8 in volume, and increasingly ask for hot-dip galvanised rather than plated because coastal humidity eats plating within a season.
Landed into Tanzania
Routing, lead time and specification.
Corridor
Dar es Salaam is the Central Corridor gateway, feeding Tanzania inland as well as Zambia, Burundi, Rwanda and western DRC.
Lead time
6–9 weeks door to door for a container, with a further 3–7 days road transit for up-country and Copperbelt destinations.
Duty and conformity
EAC common external tariff on HS 7318 plus VAT and clearing charges. Tanzania Bureau of Standards conformity requirements apply to imported fasteners, handled through pre-shipment documentation.
Coating for Tanzanian exposure
Dar es Salaam and the coast are aggressively corrosive — hot-dip galvanised as a minimum. Inland mining sites need coatings that survive dust abrasion, so hot-dip galvanised or Dacromet over plating.

Questions from Tanzanian buyers
Bolts & nuts into Tanzania — asked and answered.
- Can you deliver against a shutdown date?
- Yes, and it is how most Tanzanian mining orders run. Give us the shutdown window and we work production and freight back from it, allowing for the inland road leg from Dar es Salaam.
- What does TBS require on imported fasteners?
- Tanzania Bureau of Standards conformity requirements apply to HS 7318 imports and are handled through pre-shipment documentation prepared with the consignment.
- Plated or galvanised for Dar es Salaam?
- Galvanised. The coast is aggressively corrosive and zinc plating is a false economy on anything exposed or semi-exposed there.
