4902.90.20.40 - Other business and professional journals and periodicals (including single issues tied together for shipping purposes)

This HTS code, 4902.90.20.40, specifically classifies "Other business and professional journals and periodicals." This category encompasses a wide range of publications intended for a specialized audience in business or professional fields, including but not limited to trade magazines, industry-specific newsletters, academic journals, and trade association publications. The inclusion of "single issues tied together for shipping purposes" indicates that bulk shipments of these types of periodicals are also covered here.

It is important to distinguish this category from its sibling, 4902.90.20.20, which covers newspapers appearing less than four times per week. While both fall under periodicals, this code is for publications with a frequency of four or more times per week and a focus on business or professional content, rather than general news. It also differs from 4902.90.20.60, which is a broader "Other" category for periodicals that do not fit into more specific subcategories.

As a leaf node, this classification does not have further subdivisions. Therefore, classification within 4902.90.20.40 relies on the primary nature of the publication. Key determinative factors include its regular publication schedule (typically weekly or more frequent), its targeted readership (business or professional circles), and its content, which is primarily focused on specific industries, trades, professions, or academic disciplines, rather than general news or entertainment.
