Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the free base form rather than salt
Free acid form of p-Hydroxyphenylglycine would classify under the preceding subheading for non-salt aromatic amino-compounds.
If for industrial use in bulk heterocyclic synthesis
If containing a heterocyclic ring structure qualifying under Chapter 29 note exclusions, it moves to heading 2933.
If put up as immunological product base
Chapter 29 excludes immunological products of heading 3002, which take precedence.

Import Tips & Compliance
• Verify stereospecificity with polarimetry data (specific rotation for d(-)-isomer) to prevent reclassification disputes
• Label as 'pharmaceutical intermediate, not for direct medicinal use' to comply with FDA import alerts on unapproved drugs
• Check for stabilizer additions per Chapter 29 note (f); excess additives may shift to heading 3824
