- High Unit Cost: Generic imports often carry a 15‑20% markup due to middle‑man fees.
- Inconsistent Quality: Sub‑par caps lead to corrosion, leakage, and costly downtime.
- Long Lead Times: Overseas suppliers average 45‑60 days, delaying plant commissioning.
- Limited Customization: Standard sizes rarely match the 600 mm‑1200 mm diameters required in heavy‑industry projects.
- Regulatory Risks: Missing certifications (CE, ISO 9001, RoHS) can halt export shipments.
Result: Project overruns, higher OPEX, and strained supplier relationships.
