Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not the specific d(-)-p-Hydroxyphenylglycine salt
Other aromatic amino-compounds with oxygen function fall under the residual subheading in the same heading.
If classified as a sugar-derived amino-acid derivative
Products of heading 2941 (antibiotics) may take precedence if the compound is primarily used in antibiotic synthesis per chapter notes.
If imported as a chemical mixture or solution exceeding chapter limits
Solutions or mixtures not qualifying under Chapter 29 note (d) or (e) shift to prepared chemical mixtures in Chapter 38.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming chemical identity, purity (>98%), and optical rotation to match d(-)-isomer specification
• Include Safety Data Sheet (SDS) and comply with TSCA registration for chemical imports; declare as research/pharma intermediate
• Avoid misclassification as finished drug by ensuring no therapeutic claims or retail packaging; common pitfall is incorrect Chapter 30 entry
