Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is hydrogen fluoride rather than sulfur dioxide
Hydrogen fluoride is a separate inorganic acid classified under its own subheading in Chapter 28.
If imported as part of a finished wine product
Wine containing sulfur dioxide as an additive is classified under beverages, not as a chemical compound.
