Hexachlorobenzene EPA Method 608 Calibration Standard
Hexachlorobenzene EPA Method 608 Calibration Standard is a certified reference material of hexachlorobenzene dissolved in methanol, used for wastewater analysis. The solution is a normal and necessary method of putting up the product for transport and safety, as allowed under Chapter 29 Note 1(e). The hexachlorobenzene itself is explicitly named under tariff item 2903.92.00, and the methanol solvent does not render it suitable for a specific use beyond general analytical purposes.
p,p'-DDT Isomeric Standard 98% Purity
p,p'-DDT Isomeric Standard 98% Purity is the pure p,p'-DDT isomer (1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane) used for environmental monitoring and GC-MS calibration. It is a separate chemically defined organic compound, explicitly named under tariff item 2903.92.00. The product is a single isomer, which is covered by Chapter 29 Note 1(a) as a chemically defined compound.
Technical DDT 75% Wettable Powder Reference
Technical DDT 75% Wettable Powder Reference is a standardized formulation of DDT containing specified impurities, used for historical pesticide residue studies. The product is a mixture of DDT with other substances, but it is presented as a reference material for research. While DDT is explicitly named under tariff item 2903.92.00, the formulation may not meet the purity requirements of Chapter 29 Note 1(a) unless the impurities are incidental to the DDT compound itself.
