Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for retail-packed solvents with added anti-dusting agents
Chapter 29 note (g) excludes additions rendering it suitable for specific retail use, moving to Chapter 38.
If erroneously declared with hydrocarbon impurities
Petroleum-derived solvents fall under Chapter 27, but pure DMF remains in Chapter 29 per exclusion notes.
