Porters 5 Forces: Wettbewerbsdruck in der Glas-, Keramik- und Steinindustrie (WZ C23) der Metropolregion München

Introduction:

• Munich is a powerhouse (refer to context: ~6 Mio Einw., Top Branchen like Luftfahrt C30 ~52k, Bau F ~35k, Elektronik C26 ~28k, Automotive C29).
• WZ C23 (Glas/Keramik/Steine) is not in the Top 20 ranking by SV-Beschäftigte, but it is a critical supplier and enabler for Munich’s dominant clusters: Bauwirtschaft, Fahrzeugbau, Elektronik und High-Tech.
• Why Porters 5 Forces? Because “hidden champions” in this segment face brutal margin pressure from energy costs, logistics, and concentrated buyers.

Apply Porters 5 Forces to WZ C23 in Munich:

1. Rivalry among existing competitors (Wettbewerb unter den bestehenden Anbietern)

• Fragmented market of local manufacturers, but pressure from national players and imports.
• High fixed costs (Kiln/Ofen), energy intensity.
• Munich specific: High real estate and labor costs (compared to Eastern Bavaria or NRW).

2. Threat of New Entrants (Bedrohung durch neue Marktteilnehmer)

• High capital barriers (production facilities, environmental permits in Bavaria).
• But: 3D printing ceramics, new material science startups from TU Munich/LMU.
• Compare to other regions: In NRW or Sachsen, traditional glass clusters are denser (e.g., Thüringen for glass). Munich relies on innovation rather than volume.

3. Bargaining Power of Suppliers (Verhandlungsmacht der Lieferanten)

• Energy suppliers (Gas/Strom) – massive impact post-2022.
• Raw material suppliers (Quarzsand, Kaolin).
• Logistics providers in the congested Munich traffic area.

4. Bargaining Power of Buyers (Verhandlungsmacht der Abnehmer)

• Concentrated buyers: BMW (~35k MA, C29), MTU Aero Engines (~5k, C30), Siemens (~12k, C26), Baugewerbe (~35k, F).
• These OEMs and construction giants dictate prices, demand JIT, sustainability certs.

5. Threat of Substitute Products (Bedrohung durch Ersatzprodukte)

• Composites, recycled plastics, carbon fiber in automotive/aerospace.
• Prefabricated wood/steel in construction vs. traditional stone/ceramics.

Strategic Recommendations for SMEs (Mittelstand):

• Vertical integration or specialization (High-tech ceramics for MedTech/Electronics).
• Energy independence (PV on halls, heat recovery).
• Proximity to R&D (TU Munich, Fraunhofer).

Comparison to other regions:

• Thüringen (Glas): Volume/Consumer.
• NRW (Steine/Erden): Heavy industry proximity.
• Munich: High-cost, high-innovation, proximity to premium OEMs.
