Osmium-Iridium Bimetal Strip
Diffusion-bonded osmium-iridium strip for wear-resistant coatings. Composite treated as alloy of predominant metal in HTS 7110.49.0050.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If brazed, not diffused bond
Note 7 mechanical cladding follows base metal tariff treatment.
If electroplated on substrate
Plating <0.5 micron classifies as millstone/磨料 under Chapter 68.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Bonding method docs distinguish mechanical clad (excluded) from diffused alloy
• Layer thickness analysis for predominant metal determination
• Not note 7 'metal clad'; metallurgical bond creates true alloy
