Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

4805.24Lower: 10% vs 35%

If mainly from recovered waste paper with Mullen burst ≥2 kPa·m²/g

Recycled pulp papers classify in 4805.24/25; virgin kraft stays in 4804.

4804.21.00Same rate: 35%

If for sack kraft specs in 60-115 g/m² range

Sack kraft meets specific stretch/tear indices for bags; condensers do not.

4823.20Lower: 10% vs 35%

If filter paper variant with honeycomb weave

Perforated or filter paper articles fall in 4823; plain condenser sheets remain paper.

Import Tips & Compliance

Document compliance with ASTM dielectric standards; customs may request proof it's not generic writing paper

Declare in rolls/sheets only; punched/perforated versions risk Chapter 4823 Jacquard card classification

Monitor for printing; motif-printed paper shifts to Chapter 49 per chapter notes
