HS Code for Single Crystal Silicon Rods
TL;DR: The primary HS code for single crystal silicon rods is 3818.00 (doped) or 2804.61 (undoped). This 2025 guide covers classification rules, regional changes like GCC 12-digit codes, US HTS mandates, and tariff tips for semiconductors and solar imports to ensure compliance.
What Are Single Crystal Silicon Rods?
Single crystal silicon rods are high-purity materials with a uniform crystal structure essential for electronics.
These rods, grown via Czochralski or float-zone processes, reach 99.9999% purity.
They serve as the base for wafers used in chips and solar cells.
- Primary applications: Semiconductors, photovoltaic cells, microelectronics.
- Market growth: Driven
- Global trade value: Exceeds $10B yearly per UN Comtrade data.
Primary HS Code for Single Crystal Silicon Rods (3818.00)
HS code 3818.00 covers doped single crystal silicon rods for electronic use.
This 6-digit code from WCO applies to chemical elements doped for semiconductor production.
Undoped versions fall under 2804.61.
| HS Code | Description | Key Notes 2025 |
|---|
| 3818.00 | Doped silicon (rods, wafers) | Semiconductor-grade; purity >99.99% |
| 2804.61 | Silicon containing ≥99.99% silicon | Undoped pure forms |
| 8541.40 | Photosensitive semiconductor devices | Processed solar cells |
| 2804.69 | Other silicon | Lower purity variants |

Undoped vs Doped Single Crystal Silicon Rods HS Classification
Distinguishing doped from undoped determines the correct HS code for single crystal silicon rods.
Doping introduces impurities like boron or phosphorus for conductivity.
- Doped: HS 3818.00 – Electronics-focused.
- Undoped: HS 2804.61 – Raw material stage.
- Test method: Spectroscopic analysis for impurity levels.
- 2025 tip: Document doping status for customs.
2025 Regional HS Code Changes Affecting Silicon Rods
National updates in 2025 impact HS code classification for single crystal silicon rods imports.
No global WCO changes until 2027, but regions adapt.
- US: HTS mandatory for all parcels post-Aug 2025 de minimis end.
- GCC: 12-digit HS codes from Jan 1 for precision in electronics.
- EU: Combined Nomenclature updates to Chapter 38 subheadings.
- China: Enhanced verification for high-tech silicon imports.

How to Classify Single Crystal Silicon Rods HS Code Step-by-Step
Follow these steps for accurate HS code classification of single crystal silicon rods.
- Assess purity: ≥99.99% silicon qualifies for Chapter 28/38.
- Check doping: Doped → 3818.00; Undoped → 2804.61.
- Determine form: Rods vs. wafers or discs.
- Verify end-use: Electronics (3818) vs. general (2804).
- Consult regional extensions: Add digits for HTS/CN.
Reference official tools like USITC HTS search.
Common Classification Challenges for Silicon Rods
HS code errors for single crystal silicon rods lead to delays and penalties.
- Purity ambiguity: Borderline cases need lab certification.
- Doping levels: Trace impurities can shift codes.
- Form factors: Ingots vs. sliced rods.
- Regional variances: 12-digit GCC requires extra detail.
- Misdeclared end-use: Solar vs. semiconductor.
