HS 270400 Coke and semi-coke of coal
Quick Answer: HS Code 270400 covers coke and semi-coke derived from coal, which are solid carbonaceous residues produced by heating coal in the absence of air. This includes retort carbon and similar products. For importers and exporters, the primary consideration is the generally duty-free status across major jurisdictions. The UK Trade Tariff and EU TARIC both show a 0.00% ad valorem duty rate for all subheadings under 270400. Similarly, the United States Harmonized Tariff Schedule (HTSUS) lists "Free" duty rates for all corresponding tariff lines. While duty rates are minimal, compliance with environmental regulations, origin rules, and any specific import/export licensing requirements for coal-derived products remains crucial for smooth customs clearance.

How to Classify This HS Code?
What products does HS 270400 cover?
This subheading covers coke and semi-coke of coal, which are solid carbonaceous residues derived from the destructive distillation of coal in the absence of air. The WCO Harmonized System Explanatory Notes for Heading 2704 specify that these products result from the carbonization of coal, typically at high temperatures for coke and lower temperatures for semi-coke, leading to a porous, high-carbon material. The USITC Harmonized Tariff Schedule and the EU TARIC system align with this definition, encompassing all forms of coke and semi-coke obtained from coal, regardless of their specific end-use, such as metallurgical coke, foundry coke, or gas coke.
What falls outside HS 270400?
The following products are excluded from HS 270400: retort carbon (a dense, non-porous form of carbon deposited on the walls of retorts during coal gasification), which is classified under Heading 3801 as artificial graphite; petroleum coke, which is a residue from petroleum refining and is classified under Heading 2713; and pitch coke, derived from coal tar pitch, which is also classified under Heading 2713. Additionally, activated carbon, even if derived from coal, is specifically excluded and classified under Heading 3802 due to its enhanced adsorptive properties, distinguishing it from basic coke and semi-coke.
What are common classification mistakes for HS 270400?
A common error is misclassifying petroleum coke or pitch coke as coal coke, leading to incorrect duty rates and potential penalties. Importers sometimes confuse the origin material, failing to distinguish between coal-derived products and those originating from petroleum or coal tar pitch. Another mistake involves classifying retort carbon under this heading, despite its distinct physical properties and specific classification under Heading 3801. Proper application of General Interpretative Rule (GRI) 1, which states that classification is determined according to the terms of the headings and any relative section or chapter notes, is crucial to avoid these errors and ensure accurate classification based on the precise nature and origin of the carbonaceous material.
How should importers classify products under HS 270400?
The correct procedure for classifying products under HS 270400 involves first verifying that the product is indeed coke or semi-coke derived exclusively from coal, not petroleum or coal tar pitch. Importers and customs brokers should obtain detailed product specifications, including the raw material source and the manufacturing process (e.g., carbonization of coal). Consulting the WCO Explanatory Notes for Chapter 27 and Heading 2704 is essential to confirm the scope. If there is any ambiguity regarding the origin or processing, a binding ruling request from the relevant customs authority (e.g., CBP in the US, national customs authorities in the EU) is recommended to ensure legal certainty and avoid classification disputes.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS code 270400 (Coke and semi-coke of coal) in major trading blocs?
For HS code 270400, the Most Favored Nation (MFN) import duty rate is generally 0.00% ad valorem in several major trading economies. Specifically:
- United States (HTSUS 2704.00.00.00): Free (0.00%) as per the U.S. International Trade Commission (USITC) Harmonized Tariff Schedule.
- European Union (TARIC 2704000000): 0.00% ad valorem, as per the EU TARIC database.
- United Kingdom (Trade Tariff 2704000000): 0.00% ad valorem, as per the UK Trade Tariff.
This indicates that coke and semi-coke of coal typically face no MFN tariffs upon importation into these regions.
What are the key classification criteria for distinguishing 'coke and semi-coke of coal' under HS 270400 from other coal products?
The primary classification criterion for HS 270400, 'Coke and semi-coke of coal,' revolves around the manufacturing process and the resulting physical properties. Coke and semi-coke are solid products obtained from the carbonization (destructive distillation in the absence of air) of coal. Key characteristics include:
- Coke: A hard, porous, high-carbon product, typically used as a fuel and reducing agent in blast furnaces. It results from high-temperature carbonization (above 900°C).
- Semi-coke: A less dense, more volatile product than coke, resulting from low-temperature carbonization (around 500-700°C). It retains more volatile matter than true coke.
This distinguishes them from raw coal (Chapter 2701) or briquettes, ovoids, and similar solid fuels manufactured from coal (Chapter 2706), which are agglomerated but not carbonized in the same manner. The WCO Explanatory Notes for Chapter 27 provide further guidance on these distinctions, emphasizing the carbonization process.
Are there any preferential duty rates or free trade agreements that specifically impact imports of HS 270400?
Given that the MFN duty rate for HS 270400 is already 0.00% (Free) in many major economies like the United States, European Union, and United Kingdom, there is generally no further reduction possible under preferential trade agreements for the duty rate itself. Products classified under HS 270400 would typically enter these markets duty-free regardless of origin, provided they meet all other import requirements.
However, importers should still be aware of:
- Rules of Origin: Even with a 0% duty rate, goods must still comply with the Rules of Origin of any applicable Free Trade Agreement (FTA) if the importer wishes to claim FTA benefits (e.g., for statistical purposes or to avoid potential future non-tariff barriers).
- Documentation: While duty may be zero, proper documentation (e.g., commercial invoice, bill of lading, origin declarations) is always required for customs clearance, regardless of FTA status or duty rate. For example, a Certificate of Origin might still be requested by customs authorities even for duty-free goods.
What specific documentation is required for the importation of coke and semi-coke of coal under HS 270400?
For the importation of coke and semi-coke of coal under HS 270400, standard customs documentation is required. While the duty rate is often 0.00%, accurate and complete documentation is crucial for smooth customs clearance. Key documents typically include:
- Commercial Invoice: Detailing the buyer, seller, description of goods (including HS code), quantity, unit price, total value, and terms of sale (Incoterms).
- Bill of Lading (for sea freight) or Air Waybill (for air freight): Proof of shipment and contract of carriage.
- Packing List: Itemizing the contents of each package, weight, and dimensions.
- Certificate of Origin: While not always strictly required for duty-free goods, it may be requested by customs to verify the country of origin for statistical purposes, trade compliance, or to confirm eligibility for any specific trade programs.
- Import License/Permit: Generally not required for coke and semi-coke in major markets, but importers should verify with the specific importing country's regulations, as some countries may have controls on certain energy products.
- Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS): May be required by environmental or health authorities, especially for industrial materials, to ensure safe handling and transportation.
