Last updated: July 2026 dataWeight-based classification governs this heading: unbleached, uncoated kraft paper and paperboard at or below 150 g/m² spans a wide range of end uses, from electrical condenser paper at the lightest basis weights to bag, sack, and general wrapping grades at heavier weights. The US schedule subdivides the heading into six 10-digit lines — including dedicated lines for condenser paper (4804311000 and 4804312000), bag and sack paper (4804314020), wrapping paper (4804314040), and broader kraft paper/paperboard categories (4804315000 and 4804316000) — making precise basis weight and end-use documentation essential at entry. Canada dominates supply, with Sweden and Ukraine also notable sources. Condenser paper lines serve the electrical insulation industry and may require additional technical specifications to support classification.

Condenser paper is a highly specialized electrical insulation substrate manufactured to tight dielectric and thickness tolerances, distinct from packaging-grade kraft paper. The two condenser lines are split by basis weight (over 15 but not over 30 g/m², and 30–150 g/m²). Importers of condenser paper should provide technical data sheets confirming dielectric properties and intended electrical end-use to support classification on those specific lines rather than the general wrapping or bag paper lines.
Classification between 4804314020 (bag/sack paper) and 4804314040 (wrapping paper) turns on the paper's construction and intended use. Bag and sack paper is engineered for extensibility and strength under filling conditions; wrapping paper is not. Mill certificates, product specifications, and purchase order descriptions indicating end-use are the primary evidence. When the distinction is genuinely ambiguous, consulting a licensed customs broker and potentially seeking a binding ruling from CBP is advisable.
