Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-alloy maraging base
Base composition determines alloy status; non-qualifying goes to basic steel headings.
If machined into space vehicle parts
Further worked into spacecraft components moves to Chapter 88.
If hot-rolled condition
All hot-rolled alloy bars precede cold-finished sequences in tariff.

Import Tips & Compliance
• Maraging steels need ultra-high strength (200+ ksi) documentation matching note (a) criteria
• Defense/aerospace end-use may trigger BIS export controls even on imports
• Age-hardening potential must be declared as-received solution-annealed condition only
