HS 690390 Other
Quick Answer: Other refractory ceramic goods imported under HS 690390 enter the UK at 4.00%, the EU at 5.00%, and the US at 30% (MFN). This residual classification applies to ceramic products designed for high-temperature applications that are not specifically listed in preceding subheadings of heading 6903. Examples include certain types of crucibles, muffles, and kiln furniture not elsewhere specified. Importers should exercise caution as this broad category can encompass a wide range of specialized items, and precise classification is crucial. CustomTariffs aggregates this data, highlighting the varying duty burdens across major markets.

How to Classify This HS Code?
What products does HS 690390 cover?
This subheading covers "other" refractory ceramic goods of a kind used in industry, not specifically enumerated in preceding subheadings of heading 6903. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this includes items like refractory bricks, blocks, tiles, and similar refractory ceramic construction materials not elsewhere specified or included. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database further clarify that this category encompasses a broad range of heat-resistant ceramic articles used in high-temperature industrial applications, such as furnace linings, kiln furniture, and crucibles, provided they are not classified under more specific headings within Chapter 69.
What falls outside HS 690390?
The following products are excluded from HS 690390: refractory ceramic goods that are specifically classified under other headings within Chapter 69, such as those for sanitary ware (heading 6910) or tableware (heading 6911). Additionally, non-refractory ceramic articles, even if used in industrial settings, are not covered. For example, ceramic insulators for electrical purposes (heading 6909) or ceramic grinding media (also heading 6909) would be classified elsewhere, as would finished articles made from refractory ceramic materials that are not primarily intended for industrial refractory use, such as decorative ceramic tiles.
What are common classification mistakes for HS 690390?
A common error is misinterpreting the "refractory" nature of the ceramic goods. If an item is not designed to withstand high temperatures (typically above 1,000°C) without significant degradation, it likely does not meet the criteria for heading 6903 and its subheadings, including 690390. Another mistake involves classifying finished ceramic products that are not primarily for industrial refractory use under this heading. For instance, ceramic components for machinery that are not heat-resistant would fall under different headings based on their specific function, following General Rule of Interpretation (GRI) 1 and GRI 3.
How should importers classify products under HS 690390?
The correct procedure for classifying products under HS 690390 involves a systematic approach. Importers and customs brokers must first consult the WCO Harmonized System Explanatory Notes and the specific tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff. They should determine if the product is a refractory ceramic article and if it is not specifically covered by a more precise heading or subheading. If the product meets the definition of "other" refractory ceramic goods not elsewhere specified, then 690390 is the appropriate classification. Verification of the product's intended use and material composition is crucial.
How is the duty calculated for products under HS 690390?
A shipment of 1,000 kilograms of specialized refractory ceramic bricks for a steel furnace, 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 7% ad valorem, applied to the declared customs value ($5,000 USD × 0.07 = $350.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 690390. Note that specific end-use provisions or other trade agreements might alter this rate.
Which trade agreements reduce duties for HS 690390?
Several free trade agreements may reduce the applicable duty rate for HS 690390, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico can enter the United States duty-free. For goods originating from countries that are beneficiaries of the Generalized System of Preferences (GSP), a preferential rate of Free may apply, as seen for certain developing nations. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific requirements of the importing country's customs authority.

FAQ
What are the typical import duty rates for HS code 690390 (Other refractory ceramic goods)?
Import duty rates for HS code 690390 can vary significantly by country. For example, the United States' Most Favored Nation (MFN) rate is 4.00% ad valorem. The European Union's TARIC system may show different rates depending on the origin and specific product. The UK Trade Tariff also lists specific rates, which can be found by searching the tariff database. It is crucial to consult the specific tariff schedule of the importing country for the exact applicable duty.
How is the import duty for HS code 690390 calculated, and can you provide an example?
The duty calculation for HS code 690390 is typically based on the ad valorem method, meaning a percentage of the declared customs value of the goods. For instance, if a shipment of refractory ceramic goods classified under 690390 has a customs value of $10,000 and the applicable duty rate is 4.00%, the import duty would be calculated as: $10,000 (Customs Value) × 0.04 (Duty Rate) = $400. Some countries may also apply specific duties (per unit) or a combination of ad valorem and specific duties, so always verify the exact duty calculation method and rate for the destination country.
What are the classification criteria for goods falling under HS code 690390?
HS code 690390 is a residual category for 'Other refractory ceramic goods.' This means it applies to ceramic products designed to withstand high temperatures (refractory) that are not specifically listed or covered by other headings within Chapter 69 of the Harmonized System. Examples include certain types of refractory bricks, shapes, tiles, and other refractory ceramic articles not elsewhere specified. Classification relies on the material composition (primarily ceramic materials like alumina, silica, magnesia, zirconia) and their intended use in high-temperature applications, such as in furnaces, kilns, or reactors. If a product has a more specific HS code, that code should be used instead.
Are there preferential duty rates available for HS code 690390 under trade agreements?
Yes, preferential duty rates may be available for HS code 690390 depending on the country of origin and the existence of trade agreements between the exporting and importing countries. For example, goods originating from countries that are part of the USMCA (United States-Mexico-Canada Agreement) or the EU's Free Trade Agreements might qualify for reduced or zero duty rates. Importers must ensure they have the necessary proof of origin documentation, such as a certificate of origin, to claim preferential treatment. Always check the specific provisions of relevant trade agreements and the importing country's tariff database for eligibility and required documentation.
What documentation is typically required for importing goods under HS code 690390?
Standard import documentation for HS code 690390 generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the specific nature of the refractory ceramic goods, additional documentation might be required. This could include a certificate of origin (especially if claiming preferential duty rates), safety data sheets (SDS) if the materials pose any hazards, or specific import licenses or permits if the goods are subject to particular regulations. Customs brokers should be consulted to ensure all necessary documentation is prepared accurately to avoid delays or penalties.
