Import Tips & Compliance
• Obtain a CDSA import permit from Health Canada, as butabarbital sodium is a controlled substance
• Verify the product is not formulated as a medicament in measured doses, which would shift classification to Chapter 30
• Provide a certificate of analysis to confirm the chemical identity and purity

5,5-Diethylbarbituric Acid Intermediate
Pure barbituric acid used as an intermediate for synthesizing 5,5-diethylbarbituric acid (barbital). It is a separate chemically defined organic compound with a pyrimidine ring, falling under tariff item 2933.52.00 as malonylurea (barbituric acid) and its salts.
Amobarbital Sodium
Amobarbital sodium is the sodium salt of amobarbital, a long-acting barbituric acid derivative with a pyrimidine ring structure. It is used medically as a sedative or hypnotic. As a salt of malonylurea (barbituric acid), it falls under tariff item 2933.52.00, which covers such compounds with a pyrimidine ring.
Barbituric Acid
Barbituric acid (malonylurea) is a heterocyclic compound with a pyrimidine ring, serving as the core scaffold for barbiturate pharmaceuticals. It is a separate chemically defined organic compound, classifiable under tariff item 2933.52.00.
Barbituric Acid Aqueous Solution
Barbituric acid dissolved in water, as permitted by Chapter 29 note (d). The aqueous solution is a normal method of putting up for safety or transport, and the solvent does not render it suitable for specific use, so it remains classifiable under tariff item 2933.52.00.
Barbituric Acid (pure)
Malonylurea, also known as barbituric acid, is the parent pyrimidine heterocyclic compound. It is directly classifiable under tariff item 2933.52.00 as the base compound and its salts, per the tariff description.
Barbituric Acid Technical Grade
Technical grade malonylurea (90-95% purity) for industrial synthesis of pharmaceutical intermediates and agrochemicals. Despite lower purity, it qualifies as a separate chemically defined compound under Chapter 29 note (a), classifiable under tariff item 2933.52.00.
