- Non-Approved Vendor Lists (AVL): Procuring from suppliers not listed on the customer’s AVL or OEM approval list can void warranties and lead to rejection during audits or quality inspections.
- Lack of Traceability: Failure to ensure lot traceability and documentation of IP rights (e.g., patent numbers, licensing agreements) can expose the buyer to legal risks and compliance issues, especially in regulated environments.
Overlooking Environmental and Regulatory Compliance
While not always directly related to IP, regulatory compliance affects quality and sourcing legality.
- Unverified VOC or REACH Compliance: Some low-cost suppliers may not comply with environmental regulations (e.g., EU REACH, VOC directives), leading to shipment rejections or project delays.
- Improper Labelling of Hazardous Components: Misrepresentation of hazardous ingredients (e.g., hexavalent chromium content) can result in safety and regulatory violations.
Mitigation Strategies
To avoid these pitfalls:
– Source only from OEM-licensed or AVL-approved suppliers.
– Require full traceability, CoC, and third-party test data.
– Audit supplier quality systems and verify IP rights.
– Conduct incoming inspections and performance testing (adhesion, corrosion resistance).
By addressing both quality and IP concerns proactively, organizations can ensure reliable performance and compliance when sourcing etch primers for aluminium.
