Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for phosphite esters rather than phosphate
Phosphorous acid esters classified differently from phosphoric acid esters in heading 2919.
If when supplied as anti-oxidant additive preparation
Antioxidant preparations containing TCP classified as Chapter 38 additive compositions.
If considered alcohol derivative rather than acid ester
Some customs interpret phenolic phosphate esters under Chapter 29 heading 2909 for ethers/alcohols.

Import Tips & Compliance
• Include ortho-cresyl content specification; high ortho-isomer versions face additional toxicity restrictions
• Declare exact isomer composition to avoid classification disputes with customs
