More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing unlisted substituents beyond basic triazine
More complex triazine derivatives may fall under the broader 'other' subheading with different statistical suffixes.
If imported as disinfectant formulation with biocides
When mixed for specific pesticidal use, it becomes a goods of Chapter 38 rather than pure compound.
If classified primarily by cyclic alcohol function over triazine
Chapter notes prioritize oxygen-function headings last in numerical order if dual characteristics apply.

Import Tips & Compliance
• Provide CAS number (108-80-5) and spectroscopic data to distinguish from triazine salts or derivatives
• Ensure declaration specifies anhydrous form to avoid confusion with hydrated versions potentially seen as mixtures
• Label for pool stabilizer end-use carefully, as formulated products may require different classification
