- High Unit Cost: Imported caps often carry 30‑45% markup due to middle‑man fees.
- Inconsistent Quality: Surface roughness > 1.6 µm leads to leaks and costly re‑work.
- Long Lead Times: 4‑6 weeks from order to delivery can stall production lines.
- Limited Customization: Standard sizes don’t fit specialized HVAC or petrochemical rigs.
- Regulatory Risks: Non‑compliant caps may fail CE, RoHS, or ISO‑9001 audits.
Result: Increased OPEX, project delays, and reduced ROI.
