HS 690310 Containing, by weight, more than 50 % of free carbon
Quick Answer: Articles of refractory ceramic materials, containing, by weight, more than 50% of free carbon, enter the UK at 4.00%, the EU at 5.00%, and the US at a rate of Free or 45% depending on specific product details. This classification covers items like graphite crucibles, furnace linings, and other heat-resistant components where carbon is the predominant constituent. Importers should be aware of potential anti-dumping duties or specific trade agreements that may influence the final duty payable in the US. According to CustomTariffs data, precise classification and origin are crucial for determining the applicable tariff.

How to Classify This HS Code?
What products does HS 690310 cover?
This subheading covers refractory ceramic goods containing, by weight, more than 50% of free carbon. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this includes products like graphite crucibles, stoppers, and other articles used in high-temperature industrial processes where resistance to heat and chemical attack is paramount. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, focusing on the carbon content as the primary defining characteristic for classification under heading 6903.
What falls outside HS 690310?
The following products are excluded from HS 690310: refractory ceramic goods that contain 50% or less free carbon by weight, or those that do not meet the definition of refractory ceramic goods. For instance, carbon-based materials not intended for high-temperature refractory applications, such as graphite electrodes for electric arc furnaces (typically classified under heading 8545), or carbon blocks used for structural purposes, would be classified elsewhere. The key differentiator remains the intended use as a refractory material and the specified carbon content threshold.
What are common classification mistakes for HS 690310?
A common error is misinterpreting the "free carbon" content or failing to consider the overall composition of the refractory ceramic article. General Interpretative Rule 1 (GIR 1) of the Harmonized System states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers may incorrectly classify items based on a general understanding of carbon rather than the specific definition of "free carbon" in the context of refractory materials, or overlook other components that might necessitate classification under a different heading if they exceed the 50% carbon threshold or alter the primary character of the good.
How should importers classify products under HS 690310?
The correct procedure for classifying products under HS 690310 involves a detailed analysis of the product's composition and intended use. Importers and customs brokers must obtain precise technical specifications from the manufacturer, specifically detailing the percentage by weight of free carbon. This should be cross-referenced with the definitions provided in the WCO HS Nomenclature and relevant national tariff schedules, such as the USITC HTS or EU TARIC. If the free carbon content exceeds 50% and the article is designed for refractory applications, then classification under 690310 is appropriate.
How is the duty calculated for products under HS 690310?
A graphite crucible weighing 5 kg and declared at a customs value of $500 USD would attract a US duty of $25.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value. The calculation is: 5.0% × $500 USD = $25.00. This rate is published in the USITC Harmonized Tariff Schedule (HTS) for subheading 6903.10.0000. Note that specific weight-based duties or other factors could apply depending on the exact product and jurisdiction.
Which trade agreements reduce duties for HS 690310?
Several free trade agreements may reduce the applicable duty rate for HS 690310, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico may enter the United States duty-free. To claim this preference, a self-certified origin statement is typically required. For goods originating from countries benefiting from the Generalized System of Preferences (GSP) program in the EU, a EUR.1 movement certificate might be necessary to achieve a preferential rate, often resulting in a reduced duty or duty-free status, depending on the specific agreement and country of origin.

FAQ
What are the typical import duty rates for HS code 690310, which covers refractory ceramic goods containing more than 50% free carbon by weight?
The duty rates for HS code 690310 vary significantly by importing country. For example, under the United States Harmonized Tariff Schedule (US HTS), the Most Favored Nation (MFN) duty rate is 3.5% ad valorem. Under the EU's Combined Nomenclature (TARIC), the autonomous rate is 2.5% ad valorem. The UK Global Tariff lists a rate of 4.0% ad valorem. It is crucial to consult the specific tariff schedule of the destination country for the most accurate and up-to-date rates, including any preferential rates that may apply under trade agreements.
What specific criteria define goods under HS code 690310, particularly the 'more than 50% free carbon' requirement?
HS code 690310 specifically applies to refractory ceramic goods that contain, by weight, more than 50% of free carbon. 'Free carbon' refers to carbon in its elemental form, not chemically combined within other compounds. This typically includes materials like graphite or carbon black that are integral to the ceramic composition. Importers must ensure that laboratory analysis or manufacturer's declarations confirm this carbon content threshold is met to ensure correct classification. Goods not meeting this specific carbon content would likely fall under other subheadings within Chapter 69.
How is the import duty for HS code 690310 calculated, and can you provide an example?
The duty for HS code 690310 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if the MFN duty rate in the US is 3.5% and an importer declares goods under HS 690310 with a customs value of $10,000, the duty payable would be $10,000 × 3.5% = $350. Some countries may also apply specific duties based on weight or other units, or a combination of ad valorem and specific duties. Always verify the duty calculation basis in the destination country's tariff.
What documentation is typically required for importing goods classified under HS code 690310?
Standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. For HS code 690310, it is highly recommended to have a manufacturer's declaration or a certificate of analysis that specifies the composition of the ceramic goods, particularly confirming the percentage of free carbon by weight. This documentation is crucial for customs authorities to verify the HS classification and ensure compliance with any specific import regulations or standards for refractory materials.
Are there common trade agreements that offer preferential duty rates for HS code 690310, and how can importers benefit?
Preferential duty rates for HS code 690310 may be available under various free trade agreements (FTAs) or preferential trade schemes, depending on the origin of the goods and the importing country. For example, goods originating from countries with an FTA with the United States or the European Union might qualify for reduced or zero duty rates. To benefit, importers must obtain a Certificate of Origin from the exporter, demonstrating that the goods meet the rules of origin stipulated in the relevant trade agreement. This requires careful review of the specific FTA provisions and ensuring compliance with all origin requirements.
