Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported for general chemical use rather than specific photographic manufacturing
Would be classified as general aromatic sulfonamides without the specific end-use for photographic couplers
If already formulated as finished photographic color coupler
Finished photographic chemicals fall under chapter 37 rather than chapter 29 intermediates
