- High Unit Cost: Imported caps often carry a 20‑30% markup, squeezing your margin.
- Inconsistent Tolerances: Dimensional variance > 0.15 mm leads to leaks and re‑work.
- Long Lead Times: 4‑6 weeks from order to delivery disrupts JIT inventories.
- Limited Material Options: Few suppliers offer stainless‑steel or alloy variants for aggressive environments.
- Regulatory Gaps: Missing CE, FDA or RoHS certifications expose you to compliance risk.
Data point: A 2025 industry survey of 150 U.S. manufacturers shows 62% cite “cap quality” as the top cause of production downtime.
