Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as other aromatic imides not specifically named
Products not explicitly listed like Bis(o-tolyl)carbodiimide fall into the residual 'other' category within the same aromatic imides subheading.
If imported as a formulated mixture or solution for lab use
Solutions or mixtures exceeding Chapter 29 purity criteria are classified as prepared chemical preparations rather than pure compounds.
If containing organo-inorganic metal impurities affecting classification
Organo-inorganic compounds with metal atoms linked to carbon shift to heading 2931, per chapter notes excluding certain derivatives.

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.
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.
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.
