Last updated: July 2026 dataSynthetic fiber construction — typically polyester or polyester-wool blends — drives the mid-market and performance tailoring segments for men's knitted blazers. The US schedule subdivides this heading into three 10-digit lines: 6103330000 (general), 6103331000 (containing 23% or more wool by weight), and 6103332000 (other synthetic fibers), making fiber-content testing essential to correct line selection. Vietnam leads supply, followed by China; China-origin entries carry Section 301 exposure, while Vietnam-origin goods do not face that measure.

The 23% wool content threshold triggers a separate 10-digit tariff line (6103331000) with potentially different duty rates than the 'other synthetic fibers' line (6103332000). Importers must obtain accurate fiber-content test results — typically via AATCC or ISO laboratory analysis — before filing entry, since misclassification between these lines can result in underpayment or overpayment of duties and potential CBP penalties.
Classification follows the chief weight rule: if synthetic fiber (e.g., polyester) predominates by weight, the garment falls under heading 6103.33. The secondary question is then whether the wool component reaches 23% or more, directing the entry to 6103331000 rather than 6103332000. Fiber-content documentation from the manufacturer and, where borderline, independent lab testing are the standard tools for resolving this.
