HS 381519 Other
Quick Answer: Preparations for the manufacture of catalysts, not elsewhere specified, imported under HS 381519 enter the UK at 6.00%, the EU at 6.50%, and the US at 25% (MFN rate). This residual classification applies to catalyst preparations that do not fit into more specific subheadings within HS 3815. These preparations are typically mixtures containing one or more metallic compounds or oxides, designed to accelerate chemical reactions in industrial processes. Importers and customs brokers should exercise caution, as the "Other" designation necessitates careful review of product composition to ensure accurate classification and avoid potential penalties. According to CustomTariffs data, while the EU and UK maintain consistent rates, the US rate is significantly higher, presenting a key trade consideration for shipments to that market.

How to Classify This HS Code?
What products does HS 381519 cover?
This subheading covers "other" prepared binders used for the manufacture of refractory goods, not elsewhere specified or included within heading 3815. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, this category is residual for binders that do not fit the more specific descriptions of prepared binders for ceramics or for the manufacture of articles of heading 6901 to 6914. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm this residual nature, encompassing binders for refractory products that are not otherwise classified.
What falls outside HS 381519?
The following products are excluded from HS 381519: prepared binders for ceramics (classified under 3815.11 or 3815.12), and binders for the manufacture of articles of headings 6901 to 6914 (which are specifically covered by other subheadings of 3815). For instance, binders primarily intended for the production of refractory bricks or other refractory construction materials, if not fitting the specific criteria for prepared binders, might fall under different headings. Products that are not primarily binders, such as finished refractory articles themselves, are classified elsewhere.
What are common classification mistakes for HS 381519?
A common error is misinterpreting the scope of "refractory goods" or failing to distinguish between binders for refractory products and those for other ceramic articles. General Interpretive Rule 1 (GIR 1) dictates that classification shall be determined according to the terms of the headings and any relative section or chapter notes. Importers may incorrectly classify a product under 381519 when it more accurately fits a more specific subheading within 3815, or when it is not a binder at all, leading to incorrect duty assessments and potential penalties.
How should importers classify products under HS 381519?
The correct procedure for classifying products under HS 381519 involves a thorough examination of the product's composition, intended use, and how it functions as a binder for refractory goods. Importers and customs brokers must consult the WCO Harmonized System Explanatory Notes and the specific tariff schedules of the importing country, such as the USITC HTS or EU TARIC. If the product is a prepared binder for refractory materials and does not meet the criteria for more specific subheadings within 3815, then 381519 is the appropriate classification.
How is the duty calculated for products under HS 381519?
A shipment of 10,000 kilograms of a specialized refractory binder, declared at a customs value of $25,000 USD, would attract a US duty of $1,250.00. Assuming an applicable Most Favored Nation (MFN) duty rate of 5.0% ad valorem for this product under the USITC Harmonized Tariff Schedule (HTS 3815190000), the calculation is $25,000 (declared value) × 0.05 (duty rate) = $1,250.00. This calculation is based on the ad valorem rate applied to the declared customs value.
Which trade agreements reduce duties for HS 381519?
Several free trade agreements may reduce the applicable duty rate for HS 381519, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for originating goods from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for originating goods from member countries like Vietnam. To claim these preferences, a valid USMCA Certificate of Origin or a CPTPP Certificate of Origin (Form CPTPP) is typically required, depending on the specific agreement and origin country.

FAQ
What are the typical import duty rates for HS code 381519, and how do they vary by country?
HS code 381519, covering 'Other' preparations and charges for the manufacture or preparation of catalysts, falls under Chapter 38 of the Harmonized System. Duty rates can vary significantly by importing country and trade agreements. For example, the U.S. Most Favored Nation (MFN) rate is typically 6.5% ad valorem. The EU's TARIC system and the UK's Trade Tariff will show specific rates for member states and the UK, respectively, which may include preferential rates under trade agreements. Importers should consult the specific tariff schedule of the destination country for precise rates and any applicable preferential treatment.
How is the import duty for HS code 381519 calculated, and can you provide an example?
The duty for HS code 381519 is generally calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if a shipment of catalysts valued at $10,000 USD is imported into the U.S. and the MFN duty rate is 6.5%, the import duty would be $10,000 * 0.065 = $650.00. Some countries may also apply specific duties (per unit) or a combination of ad valorem and specific duties, so it is crucial to verify the exact duty calculation method in the importing country's tariff.
What specific documentation is required when importing goods classified under HS code 381519?
While the primary document is the customs declaration, importers of goods under HS code 381519 should be prepared to provide a commercial invoice detailing the value, quantity, and description of the catalyst preparations. A packing list is also essential. Depending on the specific nature of the 'other' catalyst preparations, additional documentation might be required, such as a Certificate of Origin to claim preferential duty rates, or specific safety data sheets (SDS) or technical specifications to demonstrate compliance with national regulations. Always confirm specific requirements with the customs authority of the importing country.
What are the classification criteria for 'Other' preparations and charges for the manufacture or preparation of catalysts under HS code 381519?
HS code 381519 is a residual category for catalyst preparations and charges not specifically covered by other subheadings within 3815. This typically includes mixtures or preparations containing metallic or non-metallic compounds, often supported on carriers, that are designed to facilitate chemical reactions. The key criterion is their intended use as catalysts or as components thereof in industrial processes. Classification relies on the specific composition and function of the preparation. If a preparation has a more specific use or composition that aligns with another subheading (e.g., 3815.11 for catalysts supported on charcoal, or 3815.12 for catalysts supported on precious metals), it would be classified there instead. Consult the Explanatory Notes to the Harmonized System for detailed guidance.
Which trade agreements commonly offer preferential duty rates for HS code 381519, and how can importers verify eligibility?
Many bilateral and multilateral trade agreements can provide preferential duty rates for goods classified under HS code 381519. Examples include the United States-Mexico-Canada Agreement (USMCA), agreements between the EU and various countries (e.g., CETA with Canada), and the UK's Global Tariff which incorporates rates from its independent trade deals. To verify eligibility, importers must ensure the goods meet the rules of origin stipulated in the relevant trade agreement. This typically involves obtaining a Certificate of Origin from the exporter, demonstrating that the goods are considered originating in the partner country. Importers and customs brokers should consult the specific text of the applicable trade agreement and the customs regulations of the importing country.
