1. High rejection rates – Poor‑fit end caps cause corrosion and leakage, leading to up to 12 % re‑work cost per batch.
2. Inconsistent quality – Low‑grade Chinese imports often miss ASTM A240 specifications, triggering costly QC holds.
3. Lengthy lead times – Traditional suppliers require 45‑60 days, delaying plant start‑ups and inventory turnover.
4. Compliance risk – Missing CE, RoHS, or ISO certifications can halt shipments in the EU and NA markets.
