Why Tanzania in 2026
Government building, data centres, hospitals, stadiums and hotels are the main sources of sheet metal ductwork in Tanzania in 2026. Some of these projects are finished or well advanced and some are still plans, so each one below says where it stands.
Dodoma: Mtumba Government City
Phase 2 of Mtumba Government City, about 17 km from central Dodoma, covers 26 ministry office buildings and 11 government institution offices for roughly 18,510 staff, at a reported cost of about TSh 698 billion. An inauguration set for 8 September 2026 was postponed, and later reports say President Samia Suluhu Hassan officially opened the buildings and roads on 30 October 2026. Government offices need ventilation and air conditioning, and the work is concentrated in one city, which suits a Dodoma-based shop. A health project in the same city is the cancer treatment centre at Benjamin Mkapa Hospital, reported on 28 August 2026 as costing about TSh 28.9 billion and 80% complete, with completion expected by January 2027. Earlier reports give a slightly different cost, so treat the figure as approximate. The centre is being developed with the Government of Japan.
Dar es Salaam: data centres and commercial building
Raxio has said it plans to open TZ1 on the edge of Dar es Salaam in 2026, described as Tanzania's first carrier-neutral Tier III data centre, with 800 racks, 4,000 m² and 6 MW of IT capacity. As of July 2026 it was still a plan. White space is often cooled by room or in-row units with little ductwork, but electrical rooms, offices and smoke extract need sheet metal; see our data centre duct manufacturing guide. Beyond data centres, Dar es Salaam's everyday work is offices, malls, hotels, warehouses and hospital fit-outs.
Hospitals
Beyond Mkapa, the government presented a TSh 1.2 trillion plan for a new super-specialised Muhimbili national hospital, to be built over five years, with the health ministry's 2026/27 estimates in May 2026. We found no start date, so treat it as a lead to follow. Operating theatres, isolation rooms and laboratories need tightly sealed, sometimes stainless ductwork; see our cleanroom duct guide and galvanised vs stainless comparison.
Stadiums, hotels and industrial projects
- AFCON 2027: Tanzania, Kenya and Uganda co-host the tournament, due 19 June to 18 July 2027. In September 2026 The Citizen reported the new Arusha stadium (about 30,000 seats) at 88% by government figures, the Benjamin Mkapa Stadium in Dar es Salaam at about 95% for its wider refurbishment, and the Fumba Stadium in Zanzibar (about 36,500 seats) at about 81%, due December 2026. CAF has flagged items such as lighting, backup power and hospitality areas at Mkapa. Fit-out and building services are the late stage of this work.
- Zanzibar hotels: reports cover resort openings such as Iberostar Selection Muyuni Beach, planned for 2026, and planned 2027 openings including Anantara Zanzibar at Nungwi (181 keys) and Four Seasons Resort Zanzibar. Opening dates can slip, so check each one. Resort kitchens, laundries, plant rooms and back-of-house areas use ducted ventilation, though guest rooms usually use split or VRF units with little duct.
- EACOP: the 1,443 km heated crude oil pipeline from Uganda to the Chongoleani terminal near Tanga was reported 82% complete in April 2026, and Tanzania's energy minister put it at 86% in late June 2026. Terminal and camp buildings are a small, one-off source of ductwork.
- SGR railway: the Dar es Salaam to Dodoma line has carried passengers since July 2024 and freight since June 2025, and the foundation stone for the Tabora to Kigoma section was laid on 20 July 2026. Stations, depots and workshops all need ventilation.
- Lindi LNG: the host government agreement was still unsigned as of late August 2026, with no final investment decision found. Do not plan around it yet, and check the current status.
Standards and codes for ductwork in Tanzania
We could not find a Tanzanian national standard for sheet metal duct construction. In practice a duct shop builds to what the consulting engineer's specification names.
- TBS: the Tanzania Bureau of Standards is the national standards body and a member of ISO. It publishes Tanzania Standards (TZS), many of them adoptions of ISO documents, and runs the import conformity programme described below. Check whether your client names a TZS or an international standard for galvanised coil before you order; see our gauge chart.
- SMACNA: the draft Energy Efficient Building Code (May 2025) hosted by the National Construction Council says ductwork and plenums are to be sealed in line with SMACNA guidelines, and its reference list includes ANSI/SMACNA HVAC Duct Construction Standards, the ANSI/SMACNA HVAC Air Duct Leakage Test Manual and SMACNA HVAC Systems Duct Design. The draft covers buildings of at least 1,000 m² with at least 200 kW demand and at least 150 kW of cooling load, and has duct insulation tables. It is a draft, so ask the project consultant whether it is being applied. Our air leakage classes guide explains what sealing class means for seams.
- Consultant specifications: projects led by UK, European, South African or Gulf consultants may name DW/144 or EN documents instead of SMACNA. We could not verify which is most common in Tanzania, so read the specification for each job. Our international duct standards comparison sets them side by side, and the hangers and supports guide covers the support side.
Importing duct machinery into Tanzania
- Customs duty: Tanzania applies the EAC Common External Tariff. Since 1 July 2022 it has four bands of 0, 10, 25 and 35 percent, with raw materials and capital goods generally in the 0% band. Duct forming and folding machines usually fall under HS heading 8462, but ask your clearing agent to confirm the exact line. Galvanised coil is steel and may sit in a higher band, so have it classified separately.
- VAT: 18% on imports into Mainland Tanzania, per the Tanzania Revenue Authority. Zanzibar has its own tax regime, so check it with your agent if the machine is going there.
- TBS PVoC: TBS runs Pre-shipment Verification of Conformity, with inspection in the country of export, and machinery is generally within scope. TBS also publishes an exemption guide that lists machinery and spare parts, through routes such as a Confederation of Tanzania Industries letter, or a TISEZA letter and licence with a TRA approval. Exempted goods are inspected on arrival instead. Which route fits your company is a question for your clearing agent. We supply specifications, photos and the Declaration of Conformity for the inspector.
Containers for most buyers arrive through the Port of Dar es Salaam. Tell us where your workshop is when you request a quotation, since Dodoma, Arusha and Zanzibar each need a different last leg. Rates and exemptions change with each budget, so confirm landed cost with your agent. Our importing guide covers the general paperwork.
Power supply: 400 V three phase, 50 Hz
Tanzania's standard supply is 230/400 V at 50 Hz, with a tolerance of plus or minus 10% cited in Tanzanian draft standards. Confirm the figure for your connection with TANESCO. Our standard machines are built for 380 V, 50 Hz, three phase, and we wire the motors, drives and control transformer to your measured site voltage. An auto duct line, a plasma table and a spiral tubeformer running together need a properly sized connection, so have your electrician confirm capacity with TANESCO before the machines arrive, and plan for a generator or protection if supply interruptions are common in your area.
Altitude matters upcountry. Dodoma sits at roughly 1,100 m and Arusha at about 1,400 m, and standard motor ratings assume installation up to 1,000 m, so tell us your altitude and we check motor, drive and hydraulic cooling margins. Dar es Salaam and Zanzibar are at the coast. See also duct machine voltage and frequency by country.
Typical Tanzanian shop set-ups and the machines that fit
Contractor shop, rectangular duct for offices, hotels and fit-outs
Most HVAC duct in Tanzanian commercial buildings is rectangular, and many installers make their own in a small workshop. A practical set starts with the Rectangular Duct Line II SBAL-II (0.5 to 2.0 mm sheet, 1,250 or 1,550 mm widths, feeding up to 18 m/min) or the Auto Duct Line SBAL-III, which has the same sheet range with two electrical feeding units and hydraulic notching and shearing. Add a Pittsburgh lockformer (SBLC series), which forms Pittsburgh seams in 0.4 to 1.2 mm and snap lock in 0.7 to 1.5 mm, a TDF flange forming machine (SBTDF, 35 mm flange height) for transverse joints, and a pneumatic folder (up to 1.5 mm on the 1,500 mm model) for fittings. That covers straight duct, TDF joints and most fittings with a small crew.
Volume shop for data centres, hospitals and large projects
A shop bidding for hospital, government and stadium packages needs output and consistent quality over thousands of square metres. The Auto Duct Line SBAL-V is a U-shape line for 0.5 to 1.5 mm sheet at 18 m/min, and is about 14.5 m long, so check your building length first. Pair it with the Duct Zipper SBHF-1.5×1500TDF to close seams on 0.8 to 1.5 mm duct up to 1,500 mm long, an auto corner making machine and the pneumatic corner inserting machine SBCC for TDF corners, a Plasma Cutter SBPC1550 (0.4 to 4 mm, 12 kW) for fittings from nested drawings, and a hydraulic folder for heavier gauges, up to 2.0 mm on the 1500 mm model. Hospital work to tight leakage classes rewards this consistency, because machine-formed seams and flanges seal more reliably than hand work.
Round duct
Spiral duct suits exposed ceilings, car parks, warehouses and industrial extract. The Spiral Tubeformer SBTF-1500 forms Φ80 to Φ1500 mm duct in galvanised steel from 0.4 to 1.2 mm. The SBTF-1602 extends this to Φ1600 mm and 1.3 mm, and handles aluminium as well. The Spiral Duct Flanging Machine SBFB-1600 turns flanges on round duct ends. For a real example, see Kavanagh Industries in Sydney, which added an SBTF-1602 in October 2026.
Space and logistics
The auto duct line is the longest item, with coil racks at one end and a run-out table at the other. Ask us for a layout drawing based on your building before you sign a lease, and leave room for coil deliveries, finished duct storage and truck loading. Dar es Salaam is the natural base for importing coil and shipping finished duct, while a Dodoma or Arusha shop is closer to its own projects but further from the port. SGR freight has run between Dar es Salaam and Dodoma since June 2025, so ask your agent whether rail suits your machines and coil. Our factory layout guide has worked examples. We have not quoted labour costs here because we could not verify a current figure for skilled sheet metal workers.

FAQ
Which ductwork standards are used in Tanzania?
We could not find a Tanzanian national standard for sheet metal duct construction. The Tanzania Bureau of Standards (TBS) is the national standards body and publishes Tanzania Standards, many of them national adoptions of ISO documents, but duct work is normally built to whatever the consulting engineer names in the specification. The draft Energy Efficient Building Code of May 2025, published on the National Construction Council website, refers to SMACNA for duct sealing and lists ANSI/SMACNA HVAC Duct Construction Standards and the ANSI/SMACNA HVAC Air Duct Leakage Test Manual among its references. It is a draft and applies to larger buildings, so confirm its status with the project consultant. Specifications from UK, European or South African consultants may name other documents, so always build to the specification for the job.
What voltage and frequency do duct machines need in Tanzania?
Tanzania's standard supply is 230/400 V at 50 Hz, with a tolerance of plus or minus 10% cited in Tanzanian draft standards. Confirm the figure for your connection with TANESCO. Industrial three phase machines are therefore wired for about 400 V, 50 Hz. Tell us the three phase voltage measured at your workshop and your altitude, since Dodoma sits at roughly 1,100 m and Arusha at about 1,400 m, and we wire and size the motors, drives and control transformer to suit.
What taxes apply when importing duct machinery into Tanzania?
Tanzania applies the East African Community Common External Tariff. Since 1 July 2022 it has four bands, 0, 10, 25 and 35 percent, and capital goods are generally in the 0% band. Duct forming and folding machines usually fall under HS heading 8462, but ask your clearing agent to confirm the exact tariff line before you budget. Imports into Mainland Tanzania also pay VAT at 18% according to the Tanzania Revenue Authority. Zanzibar runs its own tax regime, so check it with your agent if the machine is going to the islands. Rates and exemptions change, so confirm landed cost before you order.
Does a duct machine need TBS PVoC verification for Tanzania?
TBS runs a Pre-shipment Verification of Conformity programme, with inspection done in the country of export by appointed agents. Machinery is generally within the scope of regulated goods. TBS also publishes an exemption guide that lists machinery and spare parts among the goods that can be exempted, through routes such as a letter from the Confederation of Tanzania Industries or a TISEZA letter and licence with a TRA approval. Exempted goods are inspected on arrival instead. Ask your clearing agent which route applies to your company and your machine before it ships. We supply specifications, photos and the Declaration of Conformity for the inspector.
Where is ductwork demand in Tanzania coming from in 2026?
Demand is spread across several centres. Dodoma has the new Mtumba Government City and hospital projects such as the Benjamin Mkapa Hospital cancer centre. Dar es Salaam has commercial building and new data centre capacity such as the planned Raxio TZ1. Zanzibar is adding resort hotels. Stadium works in Dar es Salaam, Arusha and Zanzibar are tied to the 2027 Africa Cup of Nations. EACOP and the SGR railway create industrial and station building work, while the Lindi LNG project had no signed host government agreement as of late August 2026, so do not plan around it.
Which machines should a new Tanzanian duct shop start with?
A contractor shop making rectangular duct for offices, hotels and fit-outs usually starts with a rectangular duct line or auto duct line, a Pittsburgh lockformer, a TDF flange former and a folder. Add a duct zipper, corner machines and a plasma table as volume grows, and a spiral tubeformer when round duct becomes regular work. Send your duct sizes, gauges and monthly output and a Taokron engineer will propose a machine set within 12 hours.
