## Common ground
All options refer to carbon electrodes—graphite or carbon-based materials used in industrial electrical applications.
## Options at a glance
**3801.90 – Semimanufactures**
- **Defining trait:** Unfinished or partially processed electrode forms (e.g., green, baked, or re-baked) not yet ready for final use.
- **Typical examples:** Green electrodes, pre-baked electrode blanks.
- **Best fit when:** The product is in an intermediate manufacturing stage, not yet fully processed for operation.
**8545.11 – Furnace electrodes**
- **Defining trait:** Carbon electrodes specifically designed for use in electric arc furnaces (EAFs) for metal smelting.
- **Typical examples:** Large-diameter electrodes used in steelmaking furnaces.
- **Best fit when:** The electrode is intended for high-current, high-temperature furnace applications like steel production.
**8545.19 – General electrical electrodes**
- **Defining trait:** Carbon electrodes used for non-furnace electrical purposes (e.g., batteries, electrolysis, or lab equipment).
- **Typical examples:** Electrodes in aluminum electrolysis cells, battery terminals, or scientific instruments.
- **Best fit when:** The electrode serves a specialized electrical function outside of industrial furnace use.
## Key differences
| Feature | 3801.90 (Semimanufactures) | 8545.11 (Furnace) | 8545.19 (General Electrical) |
|-----------------------|----------------------------|-------------------|-------------------------------|
| Processing stage | Raw/intermediate | Finished product | Finished product |
| Primary use | Manufacturing input | Electric arc furnaces | Batteries, electrolysis, labs |
| Current/temperature | Not specified | Very high | Varies |
## How to choose
- Is the electrode still in an unprocessed or semi-finished state (e.g., green or baked)? → 3801.90
- Is it used in a large electric arc furnace for metal production? → 8545.11
- Is it used in batteries, electrolysis, or lab equipment, not in furnaces? → 8545.19
## Overlaps & pitfalls
A product may qualify under both 8545.11 and 8545.19 if it’s a furnace electrode used in a non-furnace context (e.g., repurposed for research), but the **main function** determines the correct code. If unclear, prioritize the primary use. Option 3801.90 is distinct as it refers to unfinished material—no overlap with finished electrodes
