HS 280110 Chlorine

Quick Answer: HS Code 280110 specifically covers "Chlorine," a chemical element primarily used in water purification, disinfectants, and the manufacture of various organic and inorganic compounds. Importers and exporters should note the significant variation in duty rates across major jurisdictions. In the UK, the applied tariff rate is 0.00% ad valorem. The European Union (EU TARIC) applies a 5.50% ad valorem duty. For the United States (USITC), the duty rate is 25% ad valorem, though certain preferential trade agreements or specific circumstances may allow for duty-free entry. Accurate classification is crucial to avoid penalties and ensure compliance with national customs regulations, particularly given the hazardous nature and diverse applications of chlorine.

How to Classify This HS Code?

What products does HS 280110 cover?

This subheading covers chlorine in its elemental form, as defined by the Harmonized System Nomenclature (HSN) Explanatory Notes for Heading 2801, specifically referring to the chemical element with atomic number 17. It encompasses chlorine whether in gaseous, liquid, or solidified form, provided it is chemically pure or commercially pure. This includes chlorine gas (Cl2) typically transported under pressure in cylinders or tanks, and liquid chlorine, which is chlorine gas cooled and compressed into a liquid state for easier handling and storage. The USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC system both align with this definition, classifying elemental chlorine under this specific eight-digit code.

What falls outside HS 280110?

The following products are excluded from HS 280110: compounds containing chlorine, such as hydrochloric acid (HS 2806.10), sodium hypochlorite (HS 2828.90), or other chlorates and perchlorates, which are classified under their respective chemical compound headings. Furthermore, mixtures where chlorine is not the predominant or essential character, or where it is merely a component of a larger chemical preparation, would also be excluded. For instance, certain disinfectant solutions containing chlorine compounds, rather than elemental chlorine itself, would fall under different headings, often in Chapter 38, depending on their specific composition and use. Chlorine isotopes, if separated, would also typically fall outside this heading, often under Chapter 28 or 29 depending on their specific nature and purity.

What are common classification mistakes for HS 280110?

A common error is misclassifying chlorine compounds or mixtures containing chlorine under HS 280110 instead of their specific chemical headings. Importers sometimes incorrectly assume that any product with "chlorine" in its name belongs here, overlooking the critical distinction between the elemental form and its derivatives. For example, calcium hypochlorite (bleaching powder) is often mistakenly classified as elemental chlorine, when it correctly falls under HS 2828.10. This error often stems from a failure to apply General Interpretative Rule (GRI) 1, which dictates that classification is determined according to the terms of the headings and any relative section or chapter notes, and GRI 6, which extends this principle to subheadings, ensuring that only elemental chlorine is placed here.

How should importers classify products under HS 280110?

The correct procedure for classifying products under HS 280110 involves first verifying that the product is indeed elemental chlorine (Cl2) and not a chlorine-containing compound or mixture. Importers and customs brokers should obtain a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, clearly indicating the chemical name "Chlorine" and its CAS number (7782-50-5) and purity level. This documentation is crucial for demonstrating compliance with the WCO HSN Explanatory Notes for Heading 2801. If there is any doubt regarding the elemental nature or purity, a binding ruling from the relevant customs authority (e.g., CBP in the US, HMRC in the UK, or national customs authorities in the EU) should be sought to ensure accurate and legally compliant classification, mitigating potential penalties or delays.

FAQ

What is the import duty rate for Chlorine (HS 2801.10) into the United States, and are there any preferential rates available?

For imports into the United States, the Most Favored Nation (MFN) duty rate for Harmonized System (HS) subheading 2801.10.00.00, covering 'Chlorine,' is 0.00% ad valorem as per the U.S. International Trade Commission (USITC) Harmonized Tariff Schedule (HTS). This means it is duty-free for most countries. Preferential duty rates may also apply under various Free Trade Agreements (FTAs) or special programs, often resulting in a 'Free' rate. For example, imports from countries party to agreements like USMCA (Canada and Mexico), CAFTA-DR, or other FTAs would typically enter duty-free, provided all rules of origin requirements are met. Importers should verify the specific country of origin and applicable trade agreement provisions.

What are the typical EU import duty rates for Chlorine (HS 2801.10) and how can I check for specific country preferences?

For imports into the European Union, the Common Customs Tariff (CCT) duty rate for HS code 2801.10.00, covering 'Chlorine,' is typically 5.50% ad valorem. However, the actual duty rate can be significantly lower or 'Free' under various preferential trade agreements the EU has with numerous countries. For instance, imports from countries with EU FTAs (e.g., Korea, Japan, Canada under CETA, or GSP beneficiaries) may qualify for reduced or zero duties, provided the goods meet the relevant rules of origin. Importers and customs brokers should consult the EU TARIC database (Integrated Tariff of the European Union) for the most current and country-specific duty rates, including any anti-dumping duties or quotas that might apply.

What documentation is typically required for importing Chlorine (HS 2801.10), considering its nature as a chemical?

Given that Chlorine (HS 2801.10) is a chemical, importers should be prepared to provide standard customs documentation, including a commercial invoice, packing list, and bill of lading or air waybill. Additionally, due to its hazardous nature, specific regulatory documentation is often required. This may include a Safety Data Sheet (SDS), which provides crucial information on hazards, handling, and emergency procedures. Depending on the importing country's regulations, permits or licenses from environmental or chemical control agencies may also be necessary. For example, in the U.S., the Environmental Protection Agency (EPA) or other agencies might have specific requirements. Importers should verify all national and local regulations prior to shipment.

What are the key classification criteria for ensuring a correct HS classification of Chlorine under 2801.10?

The classification of 'Chlorine' under HS 2801.10 is generally straightforward as it specifically covers the element itself. The primary criterion is the chemical identity of the product: it must be elemental chlorine (Cl2). This subheading is part of Chapter 28, which covers 'Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes.' Specifically, 2801 covers 'Halogens.' Subheading 2801.10 is dedicated solely to 'Chlorine.' Classification issues typically arise only if the product is a mixture, a compound containing chlorine, or an isotope, in which case other subheadings within Chapter 28 or 29 might be more appropriate. The World Customs Organization (WCO) Explanatory Notes for Chapter 28 confirm this direct classification for elemental chlorine.

Are there any specific trade agreements that offer preferential duty treatment for Chlorine (HS 2801.10) when importing into the UK?

Yes, for imports of Chlorine (HS 2801.10) into the United Kingdom, preferential duty treatment is available under various trade agreements. While the UK Global Tariff (UKGT) MFN rate for 2801.10.00.00 is typically 0.00% ad valorem, ensuring it is duty-free for most origins, specific agreements can still be relevant for rules of origin or other trade facilitation aspects. For instance, the UK has Free Trade Agreements (FTAs) with numerous countries (e.g., EU under the Trade and Cooperation Agreement, Japan, Canada, Australia, New Zealand). Imports from these partner countries would generally enter duty-free, provided they meet the specific rules of origin outlined in the respective agreements. Importers should consult the UK Trade Tariff for the most up-to-date and specific information, including any origin declaration requirements.
