## Common ground
Both options refer to electrodes used in electric furnaces, specifically those made from carbon or graphite materials.
## Options at a glance
**8514.90 – Furnace electrodes (general)**
- **Defining trait:** Covers electrodes designed primarily for industrial or laboratory electric furnaces, regardless of material.
- **Typical examples:** Graphite electrodes, carbon electrodes, metal-coated electrodes used in arc furnaces.
- **Best fit when:** The product is specified by function (furnace use) rather than material, or if it’s a specialized electrode not made from standard carbon/graphite.
**8545.11 – Carbon/graphite furnace electrodes**
- **Defining trait:** Specifically for electrodes made of carbon or graphite, emphasizing the material composition.
- **Typical examples:** Standard graphite electrodes used in steelmaking arc furnaces; pre-baked carbon electrodes.
- **Best fit when:** The electrode is explicitly made from carbon or graphite, especially if it’s a standard industrial product used in high-temperature processes.
## Key differences
| Feature | 8514.90 – General Furnace Electrodes | 8545.11 – Carbon/Graphite Electrodes |
|-----------------------|--------------------------------------|----------------------------------------|
| Primary focus | Function (furnace use) | Material (carbon/graphite) |
| Material specificity | Not required | Required |
| Scope | Broader (includes non-carbon types) | Narrower (only carbon/graphite) |
## How to choose
- Is the electrode made of carbon or graphite? → 8545.11
- Does it serve a furnace but not necessarily use carbon/graphite? → 8514.90
## Overlaps & pitfalls
A carbon or graphite electrode for a furnace fits **both** codes. The key is priority: if the product’s **main feature** is its material (carbon/graphite), use 8545.11. If it’s defined by function (furnace use) and material isn’t specified, use 8514.90. When in doubt, choose based on the **primary distinguishing trait**—material vs. application
