Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lightweight coated on both sides with mechanical pulp base
Light-weight coated paper has specific coating weight limits in 4810; uncoated kraft differs.
If kraft paper >150 g/m² not for condensers
Weight threshold separates subheadings; >150 g/m² kraft goes to 4804.19.
If textile-coated for capacitor reinforcement
Textile-impregnated papers classify in Chapter 59; plain kraft stays in 48.

Import Tips & Compliance
• Supply technical datasheets showing dielectric constant <3.5; generic thin paper may classify under 4802
• Use ISF filing early for electronics components; delays common due to dual-use scrutiny
• Confirm no subsidiary printing; primary electrical use must dominate per chapter notes
