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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity drops below 65% during processing
Sub-65% purity shifts to general 'other' coal tar products without specific purity designation.
If further purified and considered a cyclic hydrocarbon
Highly refined versions may be seen as aromatic hydrocarbons rather than crude distillates.
If sold as a formulated mixture for industrial use
Mixtures containing carbazole as a component are classified as chemical preparations, not pure substances.

Import Tips & Compliance
• Submit detailed purity assay reports; flakes may settle, so specify sampling method per ISO standards
• Declare exact weight percentage of carbazole to Customs; minor impurities don't affect if ≥65%

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.
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.
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.
