Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diazo- or azo-compounds derived from malononitrile intermediates
Functional group transformation to diazo/azo moves to subsequent diazoamino heading 2927 per numerical order rule.
If organo-sulfur derivatives like thiomalononitrile
Sulfur directly linked to carbon qualifies as organo-sulfur compound under heading 2930.

Import Tips & Compliance
• Include ACS certificate of analysis; lab-grade status helps distinguish from industrial grades under same HTS
• For research imports <25kg, leverage HTS 9810.00.6000 duty-free but still requires 2926.90.50.10 declaration
• Avoid glass ampoules >100ml; may be viewed as retail packing shifting to Chapter 38

Malononitrile
Malononitrile (NC-CH2-CN) is a dicyano-substituted organic compound classified under HTS 2926.90.50.10 as a nitrile-function compound due to its two cyano groups directly attached to carbon. It is a colorless liquid used primarily as a chemical intermediate in organic synthesis.
Malononitrile 99% Technical Grade
High-purity malononitrile (99% NC-CH2-CN) specifically identified under HTS 2926.90.50.10 as the named nitrile-function compound. Used in pharmaceutical intermediate synthesis and polymer production, meeting Chapter 29 requirements for separate chemically defined compounds.
Malononitrile with 0.1% Stabilizer
Malononitrile containing minimal stabilizer (0.1%) for preservation during transport, explicitly permitted under Chapter 29 note (f) and classified as HTS 2926.90.50.10. The added stabilizer does not alter its primary identity as the named dicyano compound.
