Japan is a premier source of high-value electronic components — MLCCs (Murata, TDK), oscillators (Epson, NDK), and semiconductors (Renesas, Rohm, Toshiba). Japanese-made components face only the 10% Section 122 global surcharge. For high-reliability applications where Japanese-origin components are specified, the 50-point tariff advantage over Chinese alternatives is an important landed cost factor.
On a $100,000 BOM, China incurs $60,000 in duty vs $10,000 from Japan — a difference of $50,000 per order.
| Source | Duty Rate | Duty Amount | Landed Cost |
|---|---|---|---|
| 🇨🇳 China | 60% | $60,000 | $160,000 |
| 🇯🇵 Japan | 10% | $10,000 | $110,000 |
| Savings from Japan | $50,000 | $50,000 | |

Murata manufactures high-specification MLCCs (small case sizes, high capacitance, high-voltage) primarily in Japan. Commodity MLCCs are also manufactured at Murata's China facilities. The COO on your specific Murata part number depends on which manufacturing site produced it — verify with your distributor. Japan-origin Murata MLCCs face 10% duty; China-origin Murata MLCCs face 35% (25% Section 301 + 10% Section 122).
Renesas Electronics (RA, RX, RZ microcontrollers — fabs in Naka, Tsuruoka, Takasaki), Rohm Semiconductor (SiC power devices — Kyoto and Chikugo fabs), Toshiba Electronic Devices (power semiconductors, optocouplers — Kitakyushu), and Mitsubishi Electric (power modules — Fukuoka) are major Japanese IDMs with significant domestic fab output.
The US-Japan Trade Agreement (implemented 2020) covers some agricultural goods but not electronics broadly. Japanese electronics face the standard MFN rate (typically 0% for ICs) plus the 10% Section 122 surcharge. There is no USMCA-equivalent 0% duty for Japanese electronics.
It depends on the specific part. Renesas wafer fabs are in Japan, but back-end assembly (which determines US customs COO) occurs primarily in Malaysia and the Philippines. Some Renesas parts assembled and tested entirely in Japan have Japan COO. Either way, both Malaysia and Japan face only the 10% Section 122 rate — the important point is that neither is subject to Section 301.
