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 the compound contains a precious metal as part of its structure
Precious metal compounds are classified in heading 28.43, which takes precedence over other headings in Section VI.
If the organic groups render it an organo-inorganic compound not covered by Chapter 28
Chapter 28 excludes organo-inorganic compounds unless specifically listed; this alternative applies if the phenyl groups are considered integral to the compound's classification.
If imported as a mixture or preparation for analytical use rather than a pure compound
Preparations not elsewhere specified or included may fall under this heading when not meeting the purity criteria of Chapter 28.
