Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pressed into sponge or semi-manufactured shapes
Ruthenium sponge or worked forms are semi-manufactured under 7110.49, not unwrought powder.
If already supported on catalyst carriers
Supported catalysts with precious metals classify as prepared catalysts in Chapter 38.
If palladium-dominant alloy powder
Powder alloys classified by predominant platinum group metal per classification note 4.

Import Tips & Compliance
• Certify particle size distribution to meet powder form definition in subheading notes
• Declare intended end-use if for industrial catalysis to facilitate any applicable duty relief programs
• Ensure no precious stone or jewelry classification confusion; purely metallic powder stays in 7110
