Norbornane
Norbornane is a bridged cyclic hydrocarbon (C7H12) classified as a cyclane under HTS 2902.19.0050 due to its saturated bicyclic structure with no aromatic characteristics. It serves as a key intermediate in organic synthesis and pharmaceutical production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from petroleum refining processes
Petroleum-derived cyclanes fall under Chapter 27 as liquefied natural gas products rather than separate organic chemicals.
If containing saturated acyclic components exceeding cyclic content
Acyclic saturated hydrocarbons take precedence under earlier Chapter 29 headings per classification note prioritizing numerical order.
If imported as mixture with >50% non-cyclane solvents
Chemical mixtures not meeting 'separate chemically defined compound' criteria shift to prepared chemical mixtures heading.

Import Tips & Compliance
• Verify purity levels and provide chemical analysis certificates to confirm classification as a separate chemically defined compound under Chapter 29
• Include Safety Data Sheets (SDS) documenting handling as flammable liquid; ensure DOT-compliant packaging for transport
• Avoid misclassification as petroleum derivative (Chapter 27) by proving synthetic origin through manufacturing documentation
