1. Sky‑rocketing unit costs. 2025 industry survey shows a 22 % average price increase for low‑volume imports.
2. Inconsistent material quality. 37 % of U.S. OEMs reported premature cracks due to sub‑grade cast iron.
3. Long lead times. Typical overseas shipping adds 30‑45 days, jeopardizing just‑in‑time production.
4. Limited customization. One‑size‑fits‑all dies cannot meet unique exhaust geometry for hybrid powertrains.
5. Regulatory compliance headaches. CE, ISO 9001, and RoHS certifications are often missing, risking import delays.
