4901.99.00.50 - Technical, scientific and professional books

This HTS classification, 4901.99.00.50, specifically covers technical, scientific, and professional books. These are publications designed to impart specialized knowledge, skills, or information within a particular academic, industrial, or vocational field. Examples include textbooks for higher education, scientific journals, engineering manuals, medical treatises, legal digests, and professional development guides. The content is typically factual, instructional, and aimed at an audience with a specific background or interest in a specialized area.

This category is distinct from other "other" subcategories within 4901.99. It is differentiated from 4901.99.00.40, which exclusively covers religious texts such as Bibles and prayer books. Furthermore, it does not encompass art and pictorial books, which are characterized by a significant emphasis on visual content and artistic expression rather than textual instruction or technical information.

As a leaf node, this category has no further subdivisions. Therefore, the focus remains on clearly identifying the scope of technical, scientific, and professional books based on their content and intended use. Classification under this code should consider the primary purpose of the publication; if a book contains a substantial amount of technical or scientific content alongside other material, its classification will be determined by the predominant nature of its subject matter.
