Products classified under HTS 2932.93.00.00
Piperonal (Heliotropin) Powder
Pure piperonal, also known as heliotropin, is a heterocyclic compound with an oxygen hetero-atom in a benzodioxole ring structure, classified under HTS 2932.93.00.00 as a specific aromatic aldehyde. It appears as a white to pale yellow crystalline powder with a strong vanilla-like cherry blossom fragrance, used primarily in perfumery and flavorings.
Pharmaceutical Grade Piperonal
High-purity piperonal meeting USP/EP standards for use as an intermediate in synthesizing pharmaceuticals like antipsychotics and antidepressants. This chemically defined heterocyclic oxygen compound is specifically named under HTS 2932.93.00.00, distinguishing it from general aromatic aldehydes.
Piperonal for Flavor Manufacturing
Technical grade piperonal crystals used in food flavorings to impart heliotrope notes in bakery and confectionery products. As a separate chemically defined compound under Chapter 29 note 1(a), it fits HTS 2932.93.00.00 for heterocyclic oxygen compounds.
Perfumery Grade Heliotropin Crystals
Refined heliotropin (piperonal) crystals optimized for fine fragrance compounding, offering superior stability and scent profile. Classified under HTS 2932.93.00.00 due to its status as a named heterocyclic compound with oxygen hetero-atom only.
Piperonal 10% in DEP Solution
Piperonal diluted to 10% in diethyl phthalate (DEP) solvent strictly for safe transport of this volatile compound. Qualifies under HTS 2932.93.00.00 per Chapter note 1(e) as a normal transport solution not rendered for specific use.
Stabilized Piperonal with Antioxidant
Piperonal powder with BHT stabilizer added solely for preservation during long-term storage and transport. Remains under HTS 2932.93.00.00 per Chapter note 1(f) for added stabilizers not altering general use.
Colored Piperonal for Safety Identification
Piperonal lightly tinted blue for easy visual identification in bulk chemical handling, with dye added per safety regulations. Classified HTS 2932.93.00.00 under note 1(g) as the addition facilitates identification without specific use adaptation.
Piperonal Anti-Dusting Granules
Granulated piperonal with minimal anti-dusting agent to prevent airborne particles during packaging and transport. Fits HTS 2932.93.00.00 via Chapter note 1(g) for safety additions not changing general purpose.
Research Grade Piperonal
Ultra-pure piperonal (99.9%) packaged in small quantities for laboratory synthesis of organic compounds. As a separate chemically defined heterocyclic under note 1(a), it is classified in HTS 2932.93.00.00.
Piperonal for Organic Synthesis
Industrial piperonal used as a key building block in multi-step synthesis of pharmaceuticals and agrochemicals. Specific classification under HTS 2932.93.00.00 reflects its named status in heterocyclic oxygen compounds.
Vanillin Impurity Standard Piperonal
Certified reference piperonal at 0.1% concentration in acetonitrile for HPLC calibration in vanillin purity testing. Remains Chapter 29 under note 1(d)/(e) as diluted chemically defined compound for analytical use.
Piperonal in DPG for Fragrance Transport
30% piperonal in dipropylene glycol (DPG) for safe bulk shipment to fragrance houses, qualifying under transport exception note 1(e). HTS 2932.93.00.00 applies as solvent does not adapt for specific use.
Emetic-Added Piperonal for Safety
Piperonal with trace emetic (e.g., denatonium benzoate) to prevent accidental ingestion in industrial settings. Covered by HTS 2932.93.00.00 per note 1(g) for safety odoriferous additions.
Piperonal USP Reference Standard
Official USP piperonal reference standard for assaying pharmaceutical intermediates, packaged in amber vials. Precise fit for HTS 2932.93.00.00 as pure chemically defined heterocyclic.
Bulk Piperonal Flakes
Large-quantity piperonal produced in flake form for efficient melting and compounding in flavor factories. As the named compound under heterocyclic oxygen hetero-atoms, classified HTS 2932.93.00.00.
