Engineered quartz & block yield
What it is
Engineered quartz surfaces are manufactured slabs of crushed quartz and resin, sold largely to export markets for countertops. Natural stone processing depends on block yield - how much saleable slab comes from a quarried block - with wastage a major cost
US anti-dumping duties apply to Indian quartz surface exports
Impact on industries
- Engineered quartz is a manufactured product with consistent quality and design control, unlike natural stone where the block dictates the outcome
- US anti-dumping exposure is material given export concentration, and duty determinations can reset economics without warning
- Block yield risk is unavoidable in natural stone - a block that fractures or shows unexpected variation destroys the margin on that purchase
- Quarry leases and mining clearances carry the same tenure and approval risk as other mineral concessions
- Vitrified tiles substitute for natural stone at the value end, and sawing and polishing energy cost sits between the two
