Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported primarily as an amine without emphasizing sulfur function
Amines like dimethylamino derivatives classified by nitrogen function in 2921 occur later in numerical order per Chapter 29 note 3, potentially superseding organo-sulfur heading.
If for other organo-sulfur compounds not specifically listed
If not exactly matching the 2930.10.01.00 specification, it falls into the residual organo-sulfur category 2930.90.
If when diluted in solvents for safety/transport per Chapter note (e)
Solutions of Chapter 29 compounds in solvents for transport are excluded from Chapter 29 and classified as chemical preparations in 3824.
