Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other cleaning agents exceeding 10% impurities
Chapter 29 excludes mixtures not meeting chemically defined compound criteria; classified as chemical preparations instead.
If imported as sodium gluconate salt
Salts of gluconic acid fall under the same subheading 2918.16 but separate statistical suffix from pure acid.
If formulated into retail oral hygiene preparations
End-use as consumer mouthwash shifts classification to Chapter 33 for prepared oral care products.
