Last updated: April 2026 dataPaper and paperboard cores—including bobbins, spools, and cops—are essential industrial components used to wind textiles, films, foils, tapes, and other flexible materials during manufacturing and distribution. Their classification under SITC 64291 reflects their paper-pulp or paperboard construction, distinguishing them from plastic or metal winding supports. Wall thickness, core diameter, and crush strength are the primary engineering specifications that determine suitability for high-speed winding applications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
SITC 64291 applies specifically to supports constructed of paper pulp, paper, or paperboard. Cores made primarily of plastic are classified under plastics headings, and composite cores—combining paper and plastic or metal—are classified according to the material that imparts their essential character. Importers of composite cores should have a customs broker assess the construction before entry.
Key specifications include inside diameter (ID), outside diameter (OD), wall thickness, length, and radial crush strength (RCS). For high-speed textile or film winding, dynamic balance and moisture resistance are also specified. Buyers in the film and foil industries often require cores certified to tighter dimensional tolerances than those used in general packaging applications.
