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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not kaolin coated
Uncoated sack kraft paper 60-115 g/m² with required burst/stretch specs stays in 4804.
If coated with plastics
Kaolin is inorganic; plastic coatings move to Chapter 48 coated paper headings.
If cut to size sheets ≤15cm sides
Small format sheets excluded from 4810, classified as printed/cut paper articles.

Import Tips & Compliance
• Test and document tear/tensile strength per subheading note table for sack kraft validation
• Confirm coating doesn't alter primary sack kraft characteristics for classification
• Avoid common pitfall of classifying as writing paper if graphic content exceeds subsidiary use

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.
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.
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.
Impregnated Kaolin Kraft Paperboard
Kraft paperboard sheets coated with kaolin and lightly impregnated with starch binder, 250 g/m² with kraftliner Mullen strength. Impregnation permitted under 'whether or not impregnated, but not otherwise treated' wording. Used for high-performance box liner applications.
White Top Coated Kraft Linerboard
Kraft linerboard with white kaolin top coating on print side, brown kraft reverse, 175 g/m² sheets >36x15 cm. Meets kraftliner strength, white top for improved printing on boxes. Single-side coating qualifies under both-sides possible subheading.
Wet Strength Coated Kraft Paper Roll
