HS Code for Plastic coated paperboard

HS code 4811.51 is a specific classification for bleached paper and paperboard, weighing more than 150g/m2, that has been coated, impregnated, or covered with plastics. This material is a staple in the high-end packaging industry, particularly for liquids and perishable goods. The classification falls under Chapter 48 (Paper and Paperboard). The "bleached" requirement means the fibers have been chemically treated to increase whiteness, and the weight threshold of 150g/m2 ensures the material is sturdy enough to be considered paperboard rather than thin paper. The plastic coating (typically Polyethylene) serves as a functional barrier against liquids and gases. This code is distinct because it combines specific physical properties (bleaching and weight) with a specific treatment (plastic coating). It excludes any paperboard that is not bleached or does not meet the weight requirement, as well as products where the plastic is the primary structural element.

Products Included

• Liquid packaging board for milk and juice cartons
• Bleached sulfate board (SBS) with PE coating
• High-quality plastic-coated folding boxboard
• Poly-coated bleached boards for frozen food packaging
• Plastic-laminated bleached paperboard for pharmaceutical boxes

Common Misclassification

This code is frequently confused with 4811.59, which covers unbleached plastic-coated paper or bleached paper weighing 150g/m2 or less. Another common error is classifying these items under 3921 if the plastic layer is perceived as the most important part; however, if the paperboard provides the structural integrity, 4811.51 remains the correct heading. It is also distinct from 4811.90, which is a catch-all for other coated papers not involving plastics.
