Products classified under HTS 2903.93.00.00
Pentachlorobenzene (PCBZ)
Pentachlorobenzene (ISO), a chlorinated aromatic hydrocarbon with the formula C6HCl5, is a white crystalline solid used primarily as an intermediate in chemical synthesis. It falls under HTS 2903.93.00.00 as a specifically named halogenated derivative of aromatic hydrocarbons per Chapter 29 notes (a). Purity typically exceeds 98% for industrial applications.
99% Pure Pentachlorobenzene Flakes
High-purity pentachlorobenzene supplied in flake form for use in organic synthesis and as a reference standard. Classified under HTS 2903.93.00.00 as the pure, separate chemically defined compound per Chapter 29 note (a), distinct from formulations or mixtures.
Pentachlorobenzene Technical Grade Powder
Technical grade pentachlorobenzene powder (95-98% purity) used in laboratory research and as a synthetic precursor for pharmaceuticals. HTS 2903.93.00.00 covers this as the named compound, allowing minor impurities per Chapter 29 note (a).
Stabilized Pentachlorobenzene Crystals
Pentachlorobenzene crystals with added stabilizer for transport stability, used in dye intermediate production. Falls under HTS 2903.93.00.00 per Chapter note (f) allowing stabilizers necessary for preservation.
Pentachlorobenzene Lab Reference Standard
Certified reference material of pentachlorobenzene for analytical calibration in environmental testing labs. Classified in HTS 2903.93.00.00 as the pure compound, not as a preparation despite small packaging.
