Bulk Piperonal Flakes
Bulk piperonal flakes are large-quantity supplies of the chemical compound piperonal, presented in flake form for efficient melting and compounding in flavour manufacturing. Piperonal is a separate chemically defined heterocyclic compound with an oxygen hetero-atom, specifically named in tariff item 2932.93.00.
2932.93.00Colored Piperonal for Safety Identification
Colored piperonal is piperonal lightly tinted blue for safety identification in bulk chemical handling. Under Chapter 29 Note 1(g), the addition of a colouring substance to facilitate identification is permitted without changing classification, provided it does not make the product suitable for a specific use rather than general use.
2932.93.00Emetic-Added Piperonal for Safety
Emetic-added piperonal contains a trace amount of denatonium benzoate or similar emetic to prevent accidental ingestion in industrial settings. Chapter 29 Note 1(g) allows the addition of an emetic for safety reasons without affecting classification, as long as the product remains suitable for general use.
2932.93.00Perfumery Grade Heliotropin Crystals
Perfumery grade heliotropin crystals are refined piperonal optimized for fine fragrance compounding, offering superior stability and scent profile. As a separate chemically defined compound named in tariff item 2932.93.00, it qualifies under Chapter 29 Note 1(a).
2932.93.00Pharmaceutical Grade Piperonal
Pharmaceutical grade piperonal is high-purity piperonal meeting USP/EP standards for use as an intermediate in synthesizing pharmaceuticals. This separate chemically defined heterocyclic compound is specifically named in tariff item 2932.93.00 and qualifies under Chapter 29 Note 1(a).
2932.93.00Piperonal 10% in DEP Solution
Piperonal 10% in DEP solution is piperonal diluted in diethyl phthalate strictly for safe transport of this volatile compound. Under Chapter 29 Note 1(e), solutions in other solvents are classifiable in this chapter if the solvent is a normal and necessary method of putting up the product for safety or transport and does not make it suitable for a specific use.
2932.93.00Piperonal Anti-Dusting Granules
Piperonal anti-dusting granules are granulated piperonal with a minimal anti-dusting agent to prevent airborne particles during packaging and transport. Chapter 29 Note 1(g) permits the addition of an anti-dusting agent for safety without changing classification, provided it does not make the product suitable for a specific use.
2932.93.00Piperonal for Flavor Manufacturing
Piperonal for flavour manufacturing is technical grade piperonal crystals used in food flavourings to impart heliotrope notes. As a separate chemically defined compound under Chapter 29 Note 1(a), it is classified in tariff item 2932.93.00.
2932.93.00Piperonal for Organic Synthesis
Piperonal for organic synthesis is industrial piperonal used as a key building block in multi-step synthesis of pharmaceuticals and agrochemicals. Its specific classification under tariff item 2932.93.00 reflects its named status as a heterocyclic compound with an oxygen hetero-atom.
2932.93.00Piperonal (Heliotropin) Powder
Piperonal (heliotropin) powder is pure piperonal, a heterocyclic compound with an oxygen hetero-atom in a benzodioxole ring structure. It is specifically named in tariff item 2932.93.00 and qualifies as a separate chemically defined compound under Chapter 29 Note 1(a).
2932.93.00Piperonal in DPG for Fragrance Transport
Piperonal in DPG for fragrance transport is a 30% solution of piperonal in dipropylene glycol for safe bulk shipment to fragrance houses. This qualifies under Chapter 29 Note 1(e) as a transport solution where the solvent does not adapt the product for a specific use.
2932.93.00Piperonal USP Reference Standard
Piperonal USP reference standard is an official USP piperonal reference standard for assaying pharmaceutical intermediates, packaged in amber vials. As a pure chemically defined heterocyclic compound, it fits tariff item 2932.93.00 under Chapter 29 Note 1(a).
2932.93.00Research Grade Piperonal
Research grade piperonal is ultra-pure piperonal (99.9%) packaged in small quantities for laboratory synthesis of organic compounds. As a separate chemically defined heterocyclic compound under Chapter 29 Note 1(a), it is classified in tariff item 2932.93.00.
2932.93.00Stabilized Piperonal with Antioxidant
Stabilized piperonal with antioxidant is piperonal powder with BHT stabilizer added solely for preservation during long-term storage and transport. Under Chapter 29 Note 1(f), added stabilizers necessary for preservation or transport do not affect classification, provided they do not make the product suitable for a specific use.
2932.93.00Vanillin Impurity Standard Piperonal
Vanillin impurity standard piperonal is a certified reference material with piperonal at 0.1% concentration in acetonitrile for HPLC calibration in vanillin purity testing. Under Chapter 29 Note 1(d) and (e), diluted chemically defined compounds for analytical use remain classifiable in this chapter.
