Foundry Coke
Foundry coke is a porous, low-ash coke derived from coal, ideal for cupola furnaces in metal casting operations. Classified under HTS 2704.00.00.50 as 'other' coal coke, whether or not agglomerated, due to its production process and fuel application.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If agglomerated into specific forms like briquettes
Agglomerated coke has distinct sub-provisions within 2704 for shaped products.
If for anthracite-based with low volatiles if not fully converted
Anthracite coal variants not exceeding 14% volatiles remain in 2701 if coking is incomplete.
If containing significant metal slag impurities
Slag or dross from coke processing with metals shifts to Chapter 26 as mineral residues.

Import Tips & Compliance
• Provide end-use declarations specifying foundry applications to support 'coke of coal' status
• Check for agglomeration (e.g
• briquettes) as it may require separate documentation under the heading
• Avoid common pitfalls by testing for sulfur content, which could trigger environmental import restrictions

Metallurgical Coke
Metallurgical coke is a high-carbon fuel produced by heating coking coal in the absence of air, used primarily in blast furnaces for iron production. It falls under HTS 2704.00.00.50 as coke of coal, not agglomerated, and classified as 'other' since it is not specified elsewhere in the heading.
Lignite Coke
Lignite coke, or brown coal coke, is produced by carbonizing lignite, used as a low-cost fuel in power generation and industrial heating. It is covered by HTS 2704.00.00.50 as coke or semicoke of lignite, in the 'other' category.
Peat Coke
Peat coke is obtained by heating peat in retorts, serving as an eco-fuel for heating and gasification plants. HTS 2704.00.00.50 includes it as coke or semicoke of peat, categorized under 'other'.
Retort Carbon
Retort carbon is a high-purity carbon produced in retorts from coal or peat, used in electrode manufacturing and chemical processes. It qualifies under HTS 2704.00.00.50 as 'retort carbon' in the 'other' category.
Coal Semicoke
Coal semicoke is a partially carbonized coal product with higher volatiles than full coke, used in cement kilns and boilers. It is included in HTS 2704.00.00.50 as semicoke of coal, under 'other'.
Briquetted Metallurgical Coke
Briquetted metallurgical coke is agglomerated coal coke formed into uniform lumps for consistent blast furnace feed. HTS 2704.00.00.50 covers it as agglomerated coke of coal in the 'other' subcategory.
