Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as molybdenum powder rather than a fabricated gauze
Powders of molybdenum are classified under this heading, while the gauze is an article.
If the precious metal content exceeds the base metal by weight
Articles of precious metals fall under Chapter 71, not Chapter 81.

Import Tips & Compliance
• Ensure the gauze is described as an industrial article, not a precious metal product, to avoid Chapter 71 classification
• Provide a lab analysis showing molybdenum predominates by weight
• Verify if the gauze qualifies for duty-free treatment under a free trade agreement
