Clay-Coated Kraft Linerboard Sheets
Rectangular sheets of kraft linerboard (150 g/m²) coated both sides with china clay, one side >36 cm and other >15 cm unfolded. Base has ≥80% sulfate fibers and Mullen strength meeting 115+ g/m² kraftliner specs. The inorganic coating qualifies it for this subheading over uncoated linerboard.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other kraft paperboard uncoated
Kraft paperboard not meeting exact kraftliner strength table but ≥80% sulfate fibers.
If non-kraft base paper
Same kaolin coating specs but base not kraft (different than sulfate process).
If corrugated medium base
Kaolin-coated corrugated paper/paperboard uses different base material heading.

Import Tips & Compliance
• Measure sheet dimensions unfolded to confirm >36cm x >15cm for this subheading
• Obtain fiber analysis certificate proving ≥80% chemical sulfate wood fibers
• Beware reclassification if printing dominates use (moves to Chapter 49)

Kraftliner Coated Paperboard Roll
Machine-finished kraftliner paperboard coated on both sides with kaolin, weighing 200 g/m² with a Mullen bursting strength of 637 kPa, supplied in rolls over 15 cm wide. It meets subheading 4804.11 kraftliner specs but is classified here due to the kaolin coating applied without other treatments. Used primarily for corrugated box manufacturing.
Coated Sack Kraft Paper Roll
Kaolin-coated sack kraft paper in rolls exceeding 15 cm width, weighing 100 g/m² with Mullen burst index >3.7 kPa·m²/g and required stretch factors. The base meets 4804.21 sack kraft specifications but kaolin coating on one side places it in this HTS. Used for multi-wall bag production.
Surface-Printed Coated Kraft Paper Roll
Kraft paper roll >15 cm wide, kaolin coated with minimal brand printing that remains subsidiary to packaging use. Weighs 90 g/m², meets sack kraft tensile/tear specs. Allowed surface decoration doesn't trigger Chapter 49 classification.
