Grinding Wheels - Diamond: Market Size & Forecast 2026

The global bonded diamond grinding wheel market sits at approximately USD 4.2 billion in 2025 (base year), held in a structurally tight balance between rising electronics and semiconductor demand, a synthetic-diamond grit feedstock cycle tightening through 2025-2026, and cumulative trade-defence measures that have layered a combined ad valorem duty stack approaching 35 percent on Chinese-origin imports entering the United States. We project the market to reach roughly USD 6.2 billion by 2032 on a 5.8 percent CAGR through the forecast window, with the electronics, aerospace, and automotive bearing segments leading the growth differential. > **Analyst Take.** The Section 301 List 3 duty on Chinese-origin diamond grinding wheels is the single most under-priced inflection in US procurement. We read the 25 percent rate as sticky through at least the next 2026-2027 USDOC administrative-review
