Marvell Technology is a fabless US semiconductor company whose chips are fabricated at TSMC (Taiwan) and Samsung (South Korea), both facing 0% MFN + 10% Section 122 = 10% total. No Section 301 applies to Taiwan or Korea origin.
Marvell Technology is headquartered in United States, but most components are manufactured in Taiwan, South Korea. For US customs purposes, the COO is where the component is manufactured — not where the company is based. Declaring United States as COO when parts ship from Taiwan is a customs violation.
