HS code 2704 covers coke and semi-coke derived from coal, lignite, or peat, alongside retort carbon for industrial and metallurgical applications.
HS Code 2704 — Coke, Semi-Coke and Retort Carbon
Coke is produced by heating coal or peat in the absence of air to remove volatile components. It is essential for smelting iron ore in blast furnaces and for manufacturing electrode-grade retort carbon.

- Metallurgical coke
- Petroleum-free retort carbon
- Foundry coke
- Lignite semi-coke
What's excluded
- Petroleum coke → use
