2942.00.03.00 - [2,2'-Thiobis(4-(1,1,3,3-tetramethyl-n-butyl)- phenolato)(2,1)]-O,O',S-(1-butanamine), nickel II 🖩

This HTS category specifically classifies organic compounds of nickel that contain at least two phenol groups linked by a sulfur atom. The key identifying features are the presence of a nickel(II) ion and the unique structural arrangement involving two (1,1,3,3-tetramethyl-n-butyl)-phenol moieties, an amine substituent, and a sulfur bridge coordinating with the nickel. These compounds are typically used in industrial applications, often as antioxidants or stabilizers in materials such as polymers.

As a terminal node within the "Other organic compounds: Aromatic or modified aromatic" hierarchy, this classification is highly specific. It is distinguished from other "Other:" sibling categories by its precise chemical composition and its exclusion of simpler organic nickel compounds or those with different structural motifs. Unlike categories that might cover general organic nickel salts or complexes, this code targets a specific, complex organonickel structure.

Since this is a leaf node, there are no further subcategories. Classification under this code requires a definitive match to the chemical structure described, emphasizing the coordination of the phenolato groups and the sulfur atom to the nickel(II) ion. Importers and exporters should ensure that their goods precisely meet the chemical and structural requirements to avoid misclassification and potential delays.
