Industrial manufacturers directory 2026
Manufacturing Companies in Turkey
Erdemir (OYAK) is the first steel name BioNixus hears from Turkish and export buyers who want a coil rather than an import invoice. Tüpraş takes refining — a plant tour that a white-good questionnaire will not explain. Şişecam takes glass. Arçelik takes appliances. Ford Otosan takes vehicles and is the OEM offtaker many tier-one halls already live for. The Ministry of Industry and Technology is the licence desk. This directory maps those plants and the ministry. It is not a list of every KOSGEB workshop on the Gebze fence.

How the market is structured
How a Ministry of Industry licence becomes a coil, a glass tonne or a vehicle
Local
Erdemir, Tüpraş, Şişecam, Arçelik, Ford Otosan, İsdemir and the OSB tail — Turkish halls that still own coil, fuels, glass, appliances and vehicles.
- Erdemir (OYAK)
- Tüpraş
- Şişecam
- Arçelik
- Ford Otosan
- İsdemir (Iskenderun Erdemir affiliate)
- TOFAŞ / other Marmara OEMs
- Marmara OSB tenant tail
- Petkim / selected petrochemicals
- KOSGEB-adjacent mid-size manufacturers
Multinational
Bosch and other Marmara foreign halls. They are often offtakers’ suppliers, not a replacement for Erdemir on the coil conversation.
- Bosch / selected MNC Marmara halls
Regional
European OEMs and retailers buy Turkish tonnes and goods. Treat them as buyers sitting outside the mill gate.
Industrial cities, SOEs & suppliers
Ministry of Industry as the licence desk, OSB authorities as landlords, plus Gebze and Iskenderun as export gates.
- Ministry of Industry and Technology
- Organised industrial zone authorities (selected OSBs)
- Gebze and Iskenderun export communities
Market structure
Coil mill versus OEM park
Erdemir sells coil. Ford Otosan buys parts and sells vehicles. Arçelik sells to retailers. Tüpraş sells fuels. Do not run those four tours as one questionnaire. A blended “Turkey manufacturing quality” score will not survive a procurement review at an OEM or a fuel wholesaler.
Iskenderun and Marmara are different export systems. Naming “the port” without the gate is how a brief invents an offtake path the mill does not use.
What is moving
What is moving industrial manufacturing in Turkey
Two steel theatres
Zonguldak-belt Erdemir and Iskenderun İsdemir do not share a quay. A single “Turkish steel” sample will invent a geography buyers do not use.
OEM supplier parks as a second map
Ford Otosan and TOFAŞ already set the calendar for many Marmara halls. A champion-only slide will miss those offtakers.
Refining versus white goods
Tüpraş and Arçelik do not share a process. Mixing those tours invents a single “Turkish industry” buyer.
OSB stamp beside the ministry licence
Zone plots need both papers. Soft openings slip on the OSB letter as often as on the ministry file.
BioNixus fieldwork
How BioNixus studies industrial manufacturing companies in Turkey
- Paired Erdemir and İsdemir mill tours so the Black Sea and Iskenderun theatres stay distinct.
- Ford Otosan supplier-park interviews held apart from any Arçelik retailer conversation.
- Tüpraş unit walks with fuel-wholesaler offtake sitting on a different guide from Şişecam.
- MoIT versus OSB licence checks against the two papers the plant manager hangs.
Questions
Frequently Asked Questions
Who licences industrial plants in Turkey?
The Ministry of Industry and Technology issues the industrial registration. Organised industrial zones add a landlord stamp. Customs sits at the export gate.
Is İsdemir separate from Erdemir?
İsdemir is the southern OYAK steel theatre. Walk it when the offtaker is Iskenderun-adjacent. A Zonguldak-only tour will under-cover that belt.
Which plants should an auto-supplier brief tour first?
Ford Otosan and TOFAŞ as OEM offtakers, then the Marmara OSB tail and Bosch-type halls. Add Erdemir if coil is in scope. Skip Tüpraş.
Which plants should a materials brief tour first?
Erdemir / İsdemir for steel, Şişecam for glass, Tüpraş if fuels are in scope. Skip Arçelik unless appliances are in scope.
How does BioNixus research Turkish manufacturers?
Erdemir and İsdemir mill tours; Ford Otosan supplier-park interviews; Arçelik and Şişecam hall walks; and MoIT versus OSB licence checks.
Does the table rank plants by Turkish tonnes?
Rows mark halls we tour, OEM parks we walk, or the ministry desk. Rows exist because we walk the mill or the OEM park, not because of output rank.
