7229.20.00.15 - Other

This HTS classification, 7229.20.00.15, covers wire made from other alloy steel, specifically silico-manganese steel. To fall under this category, the wire must be round, have a diameter less than or equal to 1.6 mm, and possess a precise chemical composition. This composition requires the wire to contain by weight less than 0.20 percent of carbon, more than 0.9 percent of manganese, and more than 0.6 percent of silicon. Furthermore, the wire must be suitable for electric arc welding.

This specific classification distinguishes itself from its sibling category, 7229.20.00.10, which covers wire of the same silico-manganese steel composition but is explicitly plated or coated with copper. Therefore, 7229.20.00.15 applies only to silico-manganese steel wire that is *not* copper-plated or coated, while still meeting all other stipulated physical and chemical characteristics and suitability for electric arc welding.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is determined by the precise adherence to the defined material composition, diameter, form, and intended use for electric arc welding. For practical classification, verification of the chemical analysis, diameter measurement, and confirmation of its welding suitability are critical.
