When you source a 25 mm end cap, the most common setbacks are:
- High Unit Price: Imported caps often carry a 30‑40 % premium due to middle‑man mark‑ups.
- Inconsistent Quality: Dimensional tolerance exceeds ±0.15 mm, leading to assembly re‑work.
- Long Lead Times: Typical shipping from China exceeds 45 days, disrupting production schedules.
- Regulatory Uncertainty: Missing CE or RoHS certification can halt EU shipments.
According to a 2025 B2B procurement survey, 57 % of U.S. manufacturers cite “price‑quality mismatch” as the top blocker for metal components.
