1️⃣ High purchase price. Many suppliers charge premium rates for low‑volume orders, inflating project budgets.
2️⃣ Inconsistent quality. Cracks, dimensional drift, and corrosion lead to costly downtime and re‑work.
3️⃣ Long lead‑times. Overseas factories often need 4‑6 weeks, delaying plant commissioning.
4️⃣ Limited customization. Standard caps rarely match unique flange‑to‑pipe tolerances, forcing engineering compromises.
5️⃣ Regulatory uncertainty. Missing CE, RoHS, or ISO certifications can stall procurement approval.
According to a 2025 industry survey, 62 % of purchasing managers cite “delivery reliability” as the top‑ranked risk factor.
