Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If shorter chain aliphatic mono-isocyanates
2929.10.2700 specifically enumerates certain aliphatics; others separate by chemical structure.
If technical grade with >5% impurities
Chapter 29 requires 'separate chemically defined' compounds; impure mixtures shift to Chapter 38.
If fully formulated as lubricant additive
Mixtures containing lubricants classified by principal function in Chapter 34, not as pure isocyanates.

Import Tips & Compliance
• 1
• Low melting point requires heated transport documentation; 2
• Provide flash point and autoignition data for hazmat declarations; 3
• Confirm chain length via GC-MS to match exact specification
