USB-C hubs & docks classify under HTS 8471.80.00 — as of , the effective U.S. duty is 37.5% from China, 12.5% from Vietnam, and 0.0% from USMCA-qualifying Mexico.
USB-C hubs, docking stations, and port replicators classify under HTS 8471.80 ("other units of automatic data processing machines"), which enters Free at the MFN base rate — CBP treats them as ADP units, not cable assemblies, even when they ship with a captive cable.
| Origin | MFN base | §301 China | §301 forced-labor | Effective |
|---|---|---|---|---|
| China | Free | 25% | 12.5% | 37.5% |
| Vietnam | Free | — | 12.5% | 12.5% |
| Mexico USMCA | — | — | — | 0.0% |
The layers add on the same entered value — MFN base, plus the 25% Section 301 (Chinese origin only), plus the 12.5% Section 301 forced-labor duty (China and Vietnam; USMCA-compliant Mexico exempt). The classification matters at the margin: a hub misfiled under the cable line 8544.42.90 would pay a 2.6% base it does not owe. As an ADP unit the base is Free, so the effective duty is the Section 301 overlay alone.

A classification guide, not customs or legal advice. The code shown is where this product type commonly enters; the correct code for your part depends on its construction and end use. Confirm with a licensed customs broker before you file, and verify current rates against the duty stack.
Know the code, then hold the origin.
The code sets the rate; the origin decides whether you pay the China layer. Kestner builds power and connectivity hardware in its own plants in both China and Vietnam and documents the country of origin per unit — so the code you plan against and the origin you elect are the ones that clear customs.
