Alternative Classifications

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

2942.00Lower: 16.2% vs 137.5%

If diluted in solvents for safety/transport without rendering specific-use suitable

Chapter note (e) allows solutions under Chapter 29 only if solely for safety/transport; otherwise, heading 2942 for other organic compounds.

2929.90.20.00Same rate: 137.5%

If for cyclic nitrogen-function compounds with similar P-N structure

Cyclic variants classify earlier in 2929; linear N,N-dimethyl specifically in 2929.90.50.15.

Import Tips & Compliance

• Label as 'for research use only' to avoid pesticide registration requirements; mislabeling causes CBP holds

• Verify no solvents present per chapter note (e); solvated forms may classify under 2942 for organic compounds in solution

• Maintain chain-of-custody documentation to prevent dual-use concerns under Chemical Weapons Convention
