Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the paper is self-adhesive
Self-adhesive tarred paper would fall under the more specific heading for self-adhesive paper, rather than the general tarred paper item.
If the paper is coated or covered with a layer of plastics
If the tarred paper also has a plastic coating that constitutes more than half the total thickness, it may be excluded from Chapter 48 and classified in Chapter 39.
If the paper has additional surface decoration or printing not merely subsidiary
If the paper is printed with motifs or pictorial representations that are not subsidiary to its primary use, it may fall under Chapter 49 instead.
