Pharmaceutical-Grade Carbazole Crystals (85% Purity)
Crystalline carbazole at 85% purity by weight, sourced from high-temperature coal tar oils with predominant aromatic content. It is specifically classified under HTS 2707.99.40.00 for carbazole meeting the purity criterion, distinguishing it from lower-grade tars. Used as an intermediate in drug synthesis like carbazole alkaloids.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Heterocyclic intermediates specifically for pharma fall under dedicated subheadings in Chapter 29.
If containing >50% benzol (benzene)
Products dominated by benzene are classified under the specific benzol subheading.
If derived from petroleum rather than coal tar
Petroleum-based residues and oils use Chapter 27 headings outside coal tar specifics.

Import Tips & Compliance
• Include GMP or USP-compliant certificates if destined for pharma; still classified here unless fully medicinal
• Document distillation origin to prevent Chapter 29 shift for perceived 'finished' chemicals

High-Purity Carbazole Powder (98%)
This is a refined carbazole powder with a purity exceeding 98% by weight, derived from high-temperature coal tar distillation where aromatic constituents predominate. It falls under HTS 2707.99.40.00 due to its carbazole content meeting or exceeding the 65% purity threshold and its classification as a coal tar distillation product. Primarily used in the production of dyes and pharmaceuticals.
Technical Grade Carbazole Flakes (70% Purity)
Technical grade carbazole in flake form with approximately 70% purity by weight, obtained from coal tar pitch distillation. Classified under HTS 2707.99.40.00 because it meets the minimum 65% purity requirement and qualifies as an aromatic-heavy coal tar product. Commonly used in pigment manufacturing and as a reagent.
Industrial Carbazole Granules (65% Purity Minimum)
Granular carbazole with a minimum purity of 65% by weight, produced from coal tar distillation featuring excess aromatic constituents. HTS 2707.99.40.00 applies directly to this purity-specified product from coal tar sources. Ideal for use in explosives, polymers, and UV stabilizers.
Refined Carbazole for Dye Production (92% Purity)
Refined carbazole at 92% weight purity, a key distillate from high-temperature coal tar with aromatics outweighing non-aromatics. Classified precisely under HTS 2707.99.40.00 for its ≥65% carbazole content. Essential raw material for azo dyes and optical brighteners.
