Alternative Classifications

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

2929.90Same rate: 137.5%

If simpler nitrogen function without full phosphoramidofluoridate structure

Other nitrogen function compounds without specific P-F alkylidene configuration use different 10-digit code.

2812.90.00Lower: 41.2% vs 137.5%

If considered primarily a halide of phosphorus

Halides of nonmetals may classify under inorganic Chapter 28 if organic functions secondary.

2933.99.22Lower: 19% vs 137.5%

If heterocyclic ring structure present

If molecule forms heterocyclic system with nitrogen-phosphorus, moves to heading 2933.

Import Tips & Compliance

• Verify CWC Schedule 2* chemical status requiring end-user certificates and import notifications

• Classify based on principal nitrogen-phosphorus function per Chapter 29 classification rules

• Avoid misclassification as pesticide intermediates under Chapter 38 by confirming lab-grade purity
