What is it?
Rock blasted and broken to size — limestone, granite, trap rock — and, with sand, the largest tonnage humans move.
Why does it matter?
Every road base, railway ballast and concrete mix is mostly this. It is low-value per tonne, so it is quarried close to where it is used and its economics are entirely about haulage distance.

“Withheld” means the USGS suppressed the figure to avoid disclosing an individual company's data — it does not mean zero. Country rows do not always sum to the world total because the source rounds each figure independently and does not always break out an “other countries” line.
