7319.40 - Safety pins and other pins:

This HTS category, 7319.40, encompasses a range of pins made from iron or steel that are not specifically classified elsewhere. It includes items commonly used for fastening or holding materials together, distinct from sewing or knitting needles. The scope extends beyond simple utility pins to include those with specific designs or purposes.

Within Section XV, Chapter 73, this category sits alongside other articles of iron or steel. The sibling category, 7319.90, specifically denotes "Other" pins, implying that 7319.40 is intended for a more defined subset of pins that do not fit into the more general "Other" designation. The parent category's description clearly indicates a grouping for pins that are not elsewhere specified or included, and 7319.40 serves to further delineate specific types within that broader classification.

To provide more granular classification, this category is subdivided into specific types of pins. Subcategory 7319.40.20 covers safety pins, characterized by their bent construction and a clasp to secure the sharp point. Subcategory 7319.40.30.00 addresses dressmakers' or common pins, typically straight pins used for temporary fastening of fabrics. Finally, subcategory 7319.40.50, also designated as "Other," captures any remaining iron or steel pins that meet the general criteria of 7319.40 but do not fall under the more specific definitions of safety pins or dressmakers'/common pins.
