Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If already processed into acetate filament
Finished cellulose acetate tow is man-made filament yarn in Chapter 55, not raw pulp.
If chemical but not dissolving grade
Other chemical woodpulps without 4702 purity fall into 4704 for non-dissolving types.
