Phenobarbital Sodium
Phenobarbital sodium is the sodium salt of phenobarbital, a barbituric acid derivative containing a pyrimidine ring structure. It is classified under HTS 2933.52.9000 as 'other' malonylurea (barbituric acid) and its salts, distinct from specific barbiturates like those in 2933.52.10. This chemically defined heterocyclic compound fits chapter 29 note (a) for separate organic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as finished tablets or capsules
Medicaments in dosage form containing barbiturates shift to Chapter 30, excluding bulk chemicals.
If specifically 5-ethyl-5-phenylbarbituric acid
Phenobarbital (base form) has its own specific subheading; salts classified as 'other'.
If containing antibiotics or polypeptides
Chapter note excludes certain derivatives; moves to antibiotics if applicable.

Import Tips & Compliance
• Verify chemical purity certificates and CoA to confirm classification as barbituric acid salt under Chapter 29
• Include DEA import permit documentation due to controlled substance status; ensure proper labeling
• Avoid misclassification as finished dosage forms (Chapter 30); ship as bulk API only
