HS Code for Lignite coke

Lignite coke is classified under HS code 2704.00, which encompasses coke and semi-coke derived from coal, lignite, or peat. The classification is determined by the thermal treatment process known as carbonization or destructive distillation. Lignite, often referred to as brown coal, undergoes heating at high temperatures in the absence of oxygen to drive off volatile matter, leaving behind a carbon-rich solid residue. This product is distinct from raw lignite because its physical and chemical properties have been fundamentally altered through heat. Under the General Rules for the Interpretation (GRI) of the Harmonized System, specifically GRI 1, the product is classified based on the terms of the headings. Since heading 2704 explicitly mentions coke and semi-coke of lignite, it takes precedence over general mineral fuel categories. The material must be in a solid state and intended for use as a fuel or a reducing agent in metallurgical processes to meet the criteria of this heading.

Products Included

• Lignite coke produced by high-temperature carbonization
• Semi-coke of lignite produced at lower temperatures
• Agglomerated lignite coke in the form of briquettes
• Retort carbon obtained as a by-product in gas works
• Lignite char used for industrial filtration or heating

Common Misclassification

Lignite coke is frequently misclassified under HS code 2702, which covers lignite that has not been carbonized. While 2702 includes dehydrated or pulverized lignite, it does not cover products that have undergone the chemical change into coke. Another common error is using HS code 3802 for activated carbon. While both are carbonaceous, 3802 is reserved for carbon that has been chemically or physically treated to increase its porosity and surface area for adsorption. Finally, coke derived from bituminous coal is classified under the same heading 2704.00 but may be distinguished at the regional subheading level (e.g., 2704.00.19) depending on the specific national tariff schedule.

FAQ

What is the HS code for Lignite coke?

The primary HS code for lignite coke is 2704.00, which covers coke and semi-coke of coal, lignite, or peat.

Is semi-coke classified differently than fully carbonized coke?

No, both coke and semi-coke derived from lignite are grouped together under HS code 2704.00 as they are both products of the distillation of mineral fuels.
