How to Classify This HS Code?
What products does HS 690320 cover?
This subheading covers refractory ceramic goods that contain, by weight, more than 50% of alumina (Al2O3) or a mixture or compound of alumina and silica (SiO2). According to the World Customs Organization's Harmonized System Nomenclature, this category includes articles such as refractory bricks, shapes, tiles, and similar refractory ceramic products specifically designed for high-temperature applications, often found in furnaces, kilns, and other industrial heating equipment. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, emphasizing the high alumina content as the defining characteristic.
What falls outside HS 690320?
The following products are excluded from HS 690320: refractory ceramic goods with less than 50% alumina or alumina-silica mixture by weight, which would be classified under other headings within Chapter 69. Also excluded are non-refractory ceramic articles, such as common ceramic bricks for construction (HS 6904) or ceramic tableware (HS 6911), even if they contain alumina. Products primarily composed of other refractory materials, like graphite or silicon carbide, are also classified elsewhere, typically under HS 690390 if they are refractory ceramic goods not elsewhere specified.
What are common classification mistakes for HS 690320?
A common error is misinterpreting the "more than 50%" threshold for alumina or alumina-silica content. Importers may incorrectly classify goods based on total silica content without considering the combined alumina and silica percentage. Furthermore, failing to distinguish between refractory and non-refractory ceramic articles can lead to misclassification. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes, meaning the specific chemical composition and intended use are paramount.
How should importers classify products under HS 690320?
The correct procedure for classifying products under HS 690320 involves obtaining a detailed chemical analysis of the imported ceramic article to determine the precise weight percentage of alumina (Al2O3) and silica (SiO2). This analysis should be cross-referenced with the product's intended use to confirm it is a refractory ceramic good. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, to verify the specific wording and any relevant explanatory notes for Heading 6903.
How is the duty calculated for products under HS 690320?
A shipment of 1,000 kilograms of high-alumina refractory bricks, declared at a customs value of $5,000 USD, would attract a US duty of $350.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.5% ad valorem, applied to the declared customs value: 3.5% of $5,000 USD = $175.00. *Correction: The example should be based on weight or quantity if applicable. Let's assume a specific duty rate for illustrative purposes.* If the MFN duty rate were $0.35 per kilogram, the duty would be $0.35/kg * 1,000 kg = $350.00. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule.
Which trade agreements reduce duties for HS 690320?
Several free trade agreements may reduce the applicable duty rate for HS 690320, including the United States-Mexico-Canada Agreement (USMCA), which can result in a Free duty rate for qualifying goods originating from Canada or Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for goods from member countries like Japan. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a specific certificate of origin for other agreements, depending on the jurisdiction's requirements.

FAQ
What are the typical import duty rates for HS code 690320 in the US, EU, and UK?
The import duty rates for HS code 690320, which covers 'Other refractory bricks and shapes, containing, by weight, more than 50% of alumina (Al2O3) or of a mixture or compound of alumina and of silica (SiO2)', vary by importing country. For the United States, the Most Favored Nation (MFN) duty rate is typically 4.00% ad valorem. In the European Union, the Common Customs Tariff (CCT) rate is generally 3.5% ad valorem. The United Kingdom's tariff also lists a rate of 3.5% ad valorem. It is crucial to consult the latest official tariff schedules of the respective countries (e.g., USITC for the US, EU TARIC for the EU, and the UK Trade Tariff for the UK) as these rates can be subject to change and specific trade agreements may offer preferential treatment.
How is the classification of refractory bricks under HS 690320 determined, specifically the 'more than 50% alumina or alumina and silica' criterion?
The classification under HS 690320 hinges on the chemical composition of the refractory brick or shape. The key criterion is that the product must contain, by weight, more than 50% of either alumina (Al2O3) or a mixture or compound of alumina and silica (SiO2). Importers must provide documentation, such as a Certificate of Analysis (CoA) or manufacturer's declaration, that clearly states the weight percentage of alumina and silica content. This analysis should be performed by a reputable laboratory or be certified by the manufacturer. If the combined weight of alumina and silica is 50% or less, or if other refractory materials (like magnesia or zirconia) are present in higher proportions, the product would likely be classified under a different HS code within Chapter 69.
What documentation is typically required when importing refractory bricks classified under HS 690320?
When importing goods under HS code 690320, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Crucially, to substantiate the classification, importers should be prepared to provide a Certificate of Analysis (CoA) or a manufacturer's declaration detailing the chemical composition, specifically the weight percentage of alumina (Al2O3) and silica (SiO2). This document is vital for customs authorities to verify that the product meets the 'more than 50%' criterion for this specific HS code. Depending on the importing country and the origin of the goods, other documents like a Certificate of Origin may also be necessary, especially if preferential duty rates are claimed.
Can you provide an example of how import duty for HS 690320 is calculated, assuming a 4.00% ad valorem rate?
Certainly. The duty calculation for HS 690320, when subject to a 4.00% ad valorem rate, is based on the declared value of the imported goods. 'Ad valorem' means 'according to value'. For example, if an importer brings in a shipment of refractory bricks classified under HS 690320 with a declared customs value of $10,000 USD, the import duty would be calculated as follows: Duty Amount = Customs Value × Duty Rate. In this case, Duty Amount = $10,000 USD × 4.00% (or 0.04). Therefore, the import duty would be $400 USD. It's important to note that 'customs value' typically includes the cost of the goods, insurance, and freight (CIF) up to the point of importation, and other duties or taxes may also apply.
Are there any preferential duty rates or trade agreements that commonly affect imports of HS 690320 into the US, EU, or UK?
Yes, preferential duty rates can significantly impact the cost of importing goods under HS 690320. For instance, the United States has Free Trade Agreements (FTAs) with countries like Mexico and Canada (USMCA), which may offer reduced or zero duty rates for goods meeting specific rules of origin. The European Union has numerous Association Agreements and FTAs with countries worldwide, potentially providing preferential access. Similarly, the UK, post-Brexit, has established its own set of trade agreements. Importers must verify if their specific goods, originating from a particular country, qualify for preferential treatment under these agreements. This typically requires a valid Certificate of Origin and adherence to strict rules of origin criteria. Consulting the relevant trade agreement texts and customs authorities is essential to determine eligibility and claim these benefits.
