Newsprint is defined by its composition (predominantly mechanical or semi-chemical pulp), its low basis weight, and its suitability for newspaper printing. Papers with a higher chemical-pulp content, higher brightness, or surface treatment for higher-quality printing generally fall under 4802. The Chapter 48 notes and heading texts provide the controlling criteria; a binding ruling from CBP can resolve borderline cases.

Newsprint has been subject to antidumping and countervailing duty proceedings in the past, and the status of any orders can change. Importers should check the current CBP and Commerce Department records for active orders or suspension agreements applicable to the specific country of origin before shipment.
