Bis(o-tolyl)carbodiimide 98% Pure Technical Grade
This technical-grade Bis(o-tolyl)carbodiimide at 98% purity is supplied for industrial organic synthesis applications like amide coupling. It remains classified under HTS 2925.19.30.00 as the named aromatic imide, as minor impurities do not exclude it from Chapter 29's chemically defined compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If impurity levels exceed 5% creating a mixture
High impurity mixtures are treated as chemical preparations outside Chapter 29's pure compound scope.
If analyzed as carboxamide derivative rather than imide
Misinterpretation of functional group could shift to adjacent carboxyamide headings, but imide structure prevails per numerical order note.

Import Tips & Compliance
• Include batch-specific CoA showing impurity levels below 2% to avoid reclassification; declare as 'pure' compound not mixture; comply with DOT shipping for corrosive properties

Bis(o-tolyl)carbodiimide
Bis(o-tolyl)carbodiimide is a specific aromatic imide-function compound used primarily as a dehydrating agent and coupling reagent in organic synthesis, particularly for peptide bond formation. It falls under HTS 2925.19.30.00 as one of the explicitly named aromatic imides, meeting Chapter 29 requirements for separate chemically defined organic compounds with imide functionality.
2,2',6,6'-Tetraisopropyldiphenylcarbodiimide (TIPC)
2,2',6,6'-Tetraisopropyldiphenylcarbodiimide, commonly known as TIPC, is a sterically hindered aromatic carbodiimide used as a coupling agent in peptide synthesis and polymer chemistry due to its stability. It is explicitly named in HTS 2925.19.30.00 as an aromatic imide derivative, qualifying under Chapter 29 for pure, chemically defined imine-function compounds.
TIPC 2,2',6,6'-Tetraisopropyldiphenylcarbodiimide Lab Grade
Lab-grade TIPC is a high-purity version of 2,2',6,6'-Tetraisopropyldiphenylcarbodiimide for research peptide synthesis, explicitly covered by HTS 2925.19.30.00 as a named aromatic imide-function compound under Chapter 29.
Bis(o-tolyl)carbodiimide with Stabilizer Additive
This form includes a stabilizer for transport stability, as permitted by Chapter 29 note (f), and is still classified as Bis(o-tolyl)carbodiimide under HTS 2925.19.30.00 since the addition is solely for preservation without specific use adaptation.
