- High unit cost – average price 15‑20% above market benchmarks.
- Inconsistent tolerance – up to ±0.15 mm deviation, causing re‑work.
- Long lead‑times – 4‑6 weeks for standard batches, delaying production lines.
- Limited material options – most suppliers only offer C110 or C260, restricting design flexibility.
- Regulatory gaps – missing RoHS, ISO 9001, or FCC certifications can block import.
Data point: 62% of US manufacturers report project delays due to supplier quality issues (2025 Industry Survey).
