- High Purchase Price: Generic imports often carry a 20‑30 % markup due to fragmented supply chains.
- Inconsistent Quality: Dimensional tolerance > ±0.2 mm leads to leaks, product recalls, and warranty claims.
- Long Lead Times: Standard 4‑6 week shipping hampers just‑in‑time production schedules.
- Limited Customization: OEM/ODM options are rare, forcing you to redesign packaging.
- Regulatory Risks: Non‑certified caps may fail CE, FCC, or RoHS audits, delaying market entry.
