Why US Buyers Struggle with Transformer Procurement

Pain Point 1 – Escalating Unit Costs

According to the 2025 International Magnetics Survey, average transformer prices in North America rose 12 % YoY, driven by limited local supply and high raw‑material tariffs.

Pain Point 2 – Inconsistent Quality & Reliability

30 % of procurement managers report failures within the first 12 months of operation, often caused by non‑CE‑certified components and inadequate testing.

Pain Point 3 – Lengthy Lead Times & Uncertain Logistics

Typical lead times exceed 45 days, with freight delays adding another 10‑15 days—costly for time‑sensitive projects such as medical equipment or renewable‑energy installations.
