Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If isopropyl (branched) isomer rather than n-propyl
While 2931.52 specifies propylphosphonic dichloride, branched variants may fall to 'other' organo-phosphorus per statistical suffixes
If hydrolyzed to phosphonic acid form
Phosphonic acids are oxygen-function compounds classified later in 2919 per Chapter Note 3 priority
If for bulk industrial mixtures diluted for safety transport
Exceeds pure compound criteria if solvent renders it suitable for specific use, per Chapter Note (e)

Import Tips & Compliance
• Label shipments with GHS corrosive pictograms and 'RQ' if exceeding reportable quantities
• Obtain end-user statements for anti-proliferation compliance due to dual-use potential
• Test for stabilizer content to ensure Chapter 29 note (f) applicability
