Commercial Phosphorus Trisulfide
Commercial phosphorus trisulfide (P4S3) is a yellow-gray crystalline powder used primarily in the manufacture of safety match heads and as a lubricant additive. It falls under HTS 2813.90.20.00 as a sulfide of phosphorus, specifically the 'other' category for commercial phosphorus trisulfide within the sulfides of nonmetals heading. This classification applies to chemically defined inorganic compounds of nonmetals per Chapter 28 notes.
Technical Grade P4S3 Powder
Technical grade phosphorus trisulfide (P4S3) powder is an industrial chemical for producing organic phosphorus compounds and as a reducing agent in metallurgy. Classified under HTS 2813.90.20.00 as 'of phosphorus' in the commercial phosphorus trisulfide subheading, it qualifies as a nonmetal sulfide per Chapter 28 exclusions and notes.
Phosphorus Sesquisulfide Flakes
Phosphorus sesquisulfide flakes, synonymous with P4S3, are supplied in flake form for match manufacturing and pyrotechnics. This product is specifically 'of phosphorus' under HTS 2813.90.20.00, distinguishing it from carbon disulfide (2813.10) as a nonmetal sulfide.
