Newsprint is defined primarily by its mechanical or groundwood fiber content (typically over 50% mechanical pulp) and its low basis weight, generally in the 40–52 g/m² range. Higher-quality uncoated papers made from chemical pulp at higher grammages fall into separate paper and paperboard categories. Fiber composition and grammage are the key classification determinants.

Some North American mills have converted newsprint capacity to other paper grades or packaging products. Importers should monitor mill conversion announcements as they can affect supply availability and lead times.
