Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel bars/sections
Aluminum diffusion creating alloy layer may exceed nonalloy limits.
If parts of mufflers or exhaust silencers
Vehicle-specific parts classify in Chapter 87.
If painted over metal coating
Additional nonmetallic coating constitutes further working.

Import Tips & Compliance
• High-temperature coating specs must match declared performance claims
• Separate from muffler assemblies to maintain Chapter 72 classification
• Aluminizing process documentation prevents alloy steel misclassification
