Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made from kraftliner with >=80% sulfate wood fibers and Mullen strength meeting table specs
Qualifies as kraftliner paperboard if it meets the specific chemical pulp content and burst strength for heavier weights over 115 g/m².
If clay-coated on one or both sides for printing
Coated paperboard shifts to Chapter 48 heading 4810, regardless of tube/core end-use, as coating is further processing.
If imported pre-formed as finished tubes or cores
Completed tube or core articles are classified as 'other paper articles' in 4823, not as raw board stock.
