Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2921.59.80Lower: 31.5% vs 35%

If imported with primary amine functionality emphasized

Amine-function compounds precede imines numerically, but specific enumeration controls.

3824.99.39Same rate: 35%

If in formulated rubber accelerator pastes

Preparations with this as active ingredient <50% classify as industrial chemical mixtures.

2902.30.00.00Same rate: 35%

If for the corresponding toluidine precursor

Unsubstituted aromatic amines used as intermediates classify in earlier oxygen-function headings.
