HTS US: 2704.00.00.XXXX
Description
This heading covers coke and semicoke derived from coal, lignite, or peat, whether or not agglomerated, as well as retort carbon. These materials are primarily used as fuels and in metallurgical processes, especially in the production of iron and steel.
The products classified here include:
- Coke: A porous, hard, and carbon-rich fuel obtained by destructive distillation of coal or lignite, often used in foundries and blast furnaces.
- Semicoke: A form of coke produced by low-temperature carbonization, containing some volatile matter.
- Retort Carbon: Carbon residues from retort processes, typically by-products of coke production.
These materials may be agglomerated or in loose form and vary in particle size and quality depending on their industrial use.
Code Hierarchy
- Section V: Mineral Products (Chapters 25-27)
- Chapter 27: Mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes
- Heading 2704: Coke and semicoke of coal, of lignite or of peat, whether or not agglomerated; retort carbon
- US HTS Code (10-digit):
2704.00.00.XX– Specifies detailed product types based on size and usage.
Detailed Breakdown of Subheadings
The 6-digit HS heading 2704 is further subdivided into more specific 10-digit subheadings to distinguish types of coke by size and application.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2704.00.00 | Coke and semicoke of coal, of lignite or of peat, whether or not agglomerated; retort carbon | General classification for all coke and semicoke types including retort carbon. |
2704.00.00.11 |
Coke larger than 100 mm (4 inches) in maximum diameter and at least 50 percent of which is retained on a 100-mm (4-inch) sieve after drop shatter testing pursuant to ASTM D 3038, of a kind used in foundries | Specialized coke used predominantly in foundries due to its large size and durability. |
2704.00.00.25 |
Other coke and semicoke | Includes coke products not meeting the specifications for foundry coke but still used industrially. |
2704.00.00.50 |
Other coke and semicoke | Catch-all category for remaining coke types, including smaller sizes or different processing levels. |
What is NOT Classified Here?
To avoid misclassification, note these exclusions:
- Coal and lignite in raw form are classified in other headings within Chapter 27, such as 2701 and 2702.
- Charcoal made by carbonization of wood or other biomasses is classified under heading 4402.
- Petroleum coke obtained from petroleum refining processes falls under different codes in Chapter 27.
Notes
- ASTM D 3038 Standard: This test determines the drop shatter resistance of foundry coke, a quality indicator for blast furnace and foundry use.
- Usage: Foundry coke (2704.00.00.11) is valued for its size and mechanical strength, critical for metallurgical processes.
- Duty Rates: Vary depending on the subheading and country of import; consult the latest USHTS for applicable tariffs.
- Environmental Regulations: Import and use of these materials may be subject to environmental regulations due to emissions during combustion.
