7312.10.10.50 - Other, stranded wire having a lay or twist of not more than 1 revolution for a length equal to the strand diameter multiplied by 8.5

This HTS category, 7312.10.10.50, specifically classifies stranded wire made from iron or steel that is not electrically insulated. The defining characteristic for inclusion in this subcategory is the physical configuration of the wire's twist. It covers stranded wire where the lay or twist is relatively loose, meaning it completes no more than one revolution over a length equivalent to 8.5 times the diameter of the individual strands. This specific twist characteristic differentiates it from other forms of stranded wire within the broader category.

Within the same hierarchical level, this classification is distinct from sibling category 7312.10.10.30, which is reserved for "Tire cord." Tire cord, while also stranded wire, is designed with specific properties and constructions intended for reinforcement within tires. This current category, 7312.10.10.50, encompasses stranded wire that does not meet the specific requirements for tire cord, and also differs from other "Other" stranded wire at the .70 designation which may have different lay or twist specifications or intended uses.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Therefore, the focus for accurate classification rests entirely on the material composition (iron or steel, specifically stainless steel as indicated by the parent context), the stranded wire construction, and the precise lay or twist measurement described. This makes the physical lay of the strand a critical determinant for proper entry under this code.
