Section X has no Section Notes. Classification rules are governed by the Chapter Notes of Chapters 47 (Pulp), 48 (Paper and paperboard) and 49 (Printed books, newspapers, pictures and other products of the printing industry; manuscripts, typescripts and plans). Key rules: Chapter 48 Note 2 defines the scope of 'paper' and 'paperboard' by weight thresholds and provides for classification of coated and laminated products. Chapter 49 covers printed matter but excludes products where printing is merely incidental to the primary use. The term 'paper' throughout the Nomenclature extends to all fibrous webs of cellulosic material.
