HS Code for Semiconductor Wafers (HS 3818)
Doped silicon (and germanium, gallium arsenide) wafers for semiconductor manufacture sit under HS 3818. Undoped polysilicon is 2804.61. The regulatory choke-point is US export controls on advanced-node fabrication equipment and finished chips to China, mirrored by the Netherlands and Japan (ASML, Tokyo Electron).
Sample 6-digit codes
| Code | Description |
|---|---|
| 3818.00 | Chemical elements doped for use in electronics, in the form of discs, wafers or similar forms |
| 2804.61 | Silicon containing >= 99.99% by weight of silicon |
| 8542.31 | Processors and controllers (finished chips) |
| 8486.20 | Machines and apparatus for the manufacture of semiconductor devices (equipment) |
Typical import duty by market
| Market | Duty |
|---|---|
| European Union | 0% ITA-covered; EU Chips Act subsidises fabs. |
| United States | 0% Plus 25% Section 301 on Chinese-origin semiconductor items from 2025. |
| China | 0-4% Plus 13% VAT; China Big Fund invests in domestic capacity. |
| India | 0-4% Semicon India Programme subsidies for OSAT / ATMP. |

- · EU Chips Act (Regulation 2023/1781) - EUR 43bn framework; support for pilot lines and fabs.
- · US CHIPS and Science Act - USD 52bn subsidy plus 25% ITC for fab construction.
- · Foreign Direct Product Rule (FDPR) extensions - most-controversial extraterritorial reach.
- · Taiwan (TSMC)
- · South Korea (Samsung, SK Hynix)
- · USA (Intel, Micron)
- · Netherlands (ASML equipment)
- · Japan (TEL, wafer materials)
Frequently asked questions
Polysilicon feedstock is 2804.61 (chemical). Once cast into ingots, sliced, polished and doped for electronic use, it becomes 3818. Solar-grade polysilicon that never enters semiconductor use often stays in 2804.61.
The Oct 2022, Oct 2023 and Dec 2024 rules restrict export to China of: (i) logic chips at advanced nodes, (ii) HBM memory above stipulated performance, (iii) EUV/DUV lithography, (iv) etch, deposition, and inspection tools, (v) US-person support to specified fabs. FDPR extends controls to foreign-made items using US technology.
