Industry: Semiconductor Manufacturing & Microelectronics (B2B)
Jurisdiction: Germany
Primary Regulator: General Commercial Law (HGB)
Important Safety Warning: Beware of fake customer service numbers on search engines. Scammers frequently target corporate engineering and IT departments with “support portal” phishing emails, claiming your Infineon Developer account has been suspended. Infineon staff will never demand you pay a supply invoice to a new, unverified bank account via a generic email link, nor will they ask for your internal portal passwords.
Level 1: Customer Support (Kundenservice)
- How to complain:
- For Broken Consumer Electronics (e.g., Laptops, Cars, Chargers): Stop! If a product containing an Infineon microchip fails, you must complain directly to the retailer or the manufacturer of the final product. Infineon is not your legal contractual partner.
- For Corporate Engineers & Developers: Log into the myInfineon portal to submit a direct ticket via “myCases,” or ask technical questions on the Infineon Developer Community.
- For B2B Clients & Direct Support: Contact the Infineon Technologies AG central corporate switchboard at +49 89 234 0 or use the official online contact form.
- Source Verification: Impressum - Infineon Technologies
- Availability: The central corporate hotline operates Monday to Friday during standard business hours (CET).
- Timeline: B2B commercial disputes and supply chain issues are dictated by complex international contracts and SLAs, not standard consumer 14-day timelines.
Level 2: Formal Written Complaint & Mahnung
- Who to contact: Formally escalate a direct commercial or supplier dispute by sending a registered letter with return receipt (Einschreiben mit Rückschein) to their legally registered headquarters. Address it to the Management Board, Infineon Technologies AG, Am Campeon 1-15, 85579 Neubiberg, Germany. (Ensure you use the correct 1-15 building number).
- Source Verification: Impressum - Infineon Technologies
- Timeline: A legally binding deadline of 14 days (set via your Mahnung) provides the company a strict timeframe to resolve a standard financial B2B dispute before they legally default (in Verzug geraten).
Level 3: Regulatory Authority / ADR
- Authority: The correct escalation path depends entirely on the nature of your report:
- Commercial/Consumer Disputes: Infineon Technologies AG explicitly refuses to participate in voluntary consumer arbitration boards like the Universalschlichtungsstelle.
- Corporate Compliance/Whistleblowing: To report severe supply chain violations, corruption, or export control breaches, use Infineon’s official corporate compliance reporting channels.
- Source Verification: Compliance - Infineon
Level 4: Legal Action
- Pre-Litigation: Before initiating formal court proceedings, commercial entities should seek case-specific legal assistance from a specialized corporate or contract lawyer.
- Court/Arbitration: Critical Legal Trap: Private consumers attempting to sue Infineon AG directly for a consumer electronics failure will have their lawsuit dismissed by German civil courts due to a lack of privity of contract (Vertragsrelativität). Consumers must sue their seller/dealership. Commercial B2B disputes against Infineon are typically handled via private commercial arbitration or the competent Regional Court (Landgericht München).
