Assumptions and caveats

Classification depends on upper material, sole material, construction, and use.
Section 301 and product-specific exclusions can change the result. Verify Chapter 99 and entry-date treatment.
AD/CVD is not resolved by HTS alone and should be reviewed separately when risk exists.
