Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mainly straw pulp with CMT crush resistance
Straw-based fluting paper under 4805.12 if mechanical/chemical pulped, not pure wood condenser tissue.
If kraftliner >115 g/m² with Mullen burst ≥393 kPa
High-strength kraft paper for packaging shifts to 4804 if meeting kraftliner specs.
If perforated for Jacquard machines
Chapter note specifies perforated cards go to 4823 as other paper articles.

Import Tips & Compliance
• Include dielectric test reports showing tan delta <0.005 at 1kHz to substantiate condenser classification during customs review
• Avoid common error of declaring in bulk packs as 'articles'—must be rolls/sheets per chapter note 3
• Label with exact grammage and confirm ≥80% wood fiber content if sulfate process to align with related notes
