0405.10.05.00 - Described in general note 15 of the tariff schedule and entered pursuant to its provisions

This HTS category, 0405.10.05.00, specifically covers butter that meets the criteria outlined in general note 15 of the Harmonized Tariff Schedule. General note 15 provides specific definitions and conditions for classifying certain dairy products, and when butter falls under these provisions, it is classified here. This designation is crucial for determining applicable duties, quotas, and other trade regulations.

It is important to differentiate this classification from its siblings. HTS code 0405.10.10.00 applies to butter that is entered pursuant to additional U.S. note 6 to chapter 4, which likely outlines specific import requirements or preferential treatment for certain types of butter. The "Other" category, 0405.10.20.00, serves as a residual classification for any butter that does not qualify for the specific provisions of 0405.10.05.00 or 0405.10.10.00. Therefore, classification under 0405.10.05.00 hinges on strict adherence to the requirements stipulated in general note 15.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Products classified here represent a distinct category of butter defined by the specific legal and regulatory framework of general note 15, distinguishing it from other butter entries based on differing criteria.
