Lead times beyond three months are common for capital equipment, long-lead electronic components, transformers and switchgear, custom industrial machinery, and construction materials during supply crunches. At this range, most planners add a safety buffer of 1–2 weeks or more on top of the quoted lead time, and re-confirm dates with the supplier at least once mid-way.
Real-world lead times, record builds, and famous waits — every fact sourced.
