How to Classify This HS Code?
What products does HS 381119 cover?
This subheading covers "Other" anti-knock preparations for gasoline, falling under Heading 3811. According to the WCO Harmonized System Nomenclature, Heading 3811 specifically addresses anti-knock preparations, oxidation inhibitors, and similar preparations used to treat mineral oils. Subheading 3811.19, as defined by official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, encompasses all such preparations not specifically enumerated in subheadings 3811.11 (containing lead compounds) or 3811.19.0000 (which is often the specific code for "Other" in many national tariffs, but the general description applies). This includes a broad range of additives designed to improve fuel performance, such as those that enhance octane rating or prevent engine knocking, provided they do not contain lead compounds. The key is that they are specifically intended for use in gasoline.
What falls outside HS 381119?
The following products are excluded from HS 381119: anti-knock preparations containing lead compounds, which are classified under subheading 3811.11. Additionally, preparations for treating mineral oils other than gasoline, such as lubricating oils or diesel fuels, are generally classified under other subheadings within Heading 3811 or even in different chapters of the HS, depending on their primary function and composition. For instance, oxidation inhibitors for lubricating oils might fall under 3811.90, while fuel additives for diesel engines would be classified elsewhere. Products not specifically designed as anti-knock preparations for gasoline, even if they offer some performance enhancement, would also be excluded.
What are common classification mistakes for HS 381119?
A common error is misclassifying preparations that are not exclusively intended for gasoline. For example, multi-purpose fuel additives that can be used in both gasoline and diesel engines might be incorrectly classified under 3811.19 if their primary function is not solely to act as an anti-knock agent for gasoline. Another mistake involves overlooking the exclusion of lead-containing preparations, which must be classified under 3811.11. Importers may also fail to consider General Rule of Interpretation (GRI) 3(b) for mixtures or composite goods, where the classification is determined by the essential character of the product, potentially leading to misclassification if the dominant component or function is not correctly identified.
How should importers classify products under HS 381119?
The correct procedure for classifying products under HS 381119 involves a thorough examination of the product's composition, intended use, and function. Importers and customs brokers must consult the official WCO HS Nomenclature and the specific tariff schedule of the importing country, such as the USITC HTS or the EU TARIC. Key questions to ask include: Is the preparation specifically designed as an anti-knock agent for gasoline? Does it contain lead compounds? If the product is a mixture, what is its essential character? Reviewing technical data sheets, Safety Data Sheets (SDS), and manufacturer declarations is crucial to ensure accurate classification, especially when dealing with complex chemical formulations.
How is the duty calculated for products under HS 381119?
A shipment of 10,000 liters of a non-lead anti-knock preparation for gasoline, declared at a customs value of $25,000 USD, would attract a US duty of $1,250. This is calculated using the Most Favored Nation (MFN) rate of 5% ad valorem, applied to the declared customs value ($25,000 USD × 0.05 = $1,250). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for subheading 3811.19.0000. If the product were sold by weight, the duty would be calculated based on the applicable rate per unit of weight multiplied by the net weight of the product.
Which trade agreements reduce duties for HS 381119?
Several free trade agreements may reduce the applicable duty rate for HS 381119, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods may benefit from a duty rate of Free. The top origin countries benefiting from such preferential rates for this product category would typically be Canada and Mexico. To claim this preference, a valid USMCA Certificate of Origin or a self-certified origin statement meeting specific requirements is generally required by US Customs and Border Protection (CBP). Other agreements may exist depending on the importing country and the origin of the goods.

FAQ
What are the typical import duty rates for HS code 381119, and how do preferential rates apply?
HS code 381119, covering 'Other' anti-knock preparations for gasoline, has varying duty rates depending on the importing country. For example, the United States applies a Most Favored Nation (MFN) rate of 3.7¢/kg + 60%. The European Union's TARIC system may show rates such as 4.00% ad valorem for non-preferential imports. Many trade agreements offer reduced or free entry. For instance, under certain agreements like the US-Australia Free Trade Agreement (AU), goods may enter duty-free (indicated as 'Free (A+)'). Importers should always verify the specific preferential rate applicable to their country of origin and the destination country's customs tariff schedule.
How is the duty calculated for HS code 381119 when a specific duty rate like 3.7¢/kg + 60% is applied?
When a compound duty rate like 3.7¢/kg + 60% ad valorem applies to HS code 381119, the total duty is the sum of a specific duty based on weight and an ad valorem duty based on value. For example, if 1000 kg of a product valued at $5,000 USD were imported into the US, the duty calculation would be: (1000 kg * $0.037/kg) + (0.60 * $5,000 USD) = $37 USD + $3,000 USD = $3,037 USD. This calculation assumes the specific rate is in USD and the value is in USD. Always confirm the currency and units for the specific tariff.
What documentation is typically required for importing goods classified under HS code 381119?
For imports under HS code 381119, standard customs documentation is usually required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the specific nature of the 'other' anti-knock preparation, additional documentation might be necessary. This could include a certificate of origin to claim preferential duty rates, safety data sheets (SDS) for chemical products, or specific import permits if the substance is regulated. Consulting the importing country's customs authority or a customs broker is recommended.
What are the classification criteria for 'Other' anti-knock preparations under HS code 381119?
HS code 381119 falls under Chapter 38, which covers 'Miscellaneous chemical products and preparations'. Specifically, heading 3811 pertains to 'Anti-knock preparations, oxidation inhibitors, gum inhibitors, viscosity improvers, anti-corrosive preparations and similar prepared additives, for mineral oils or for other liquids used for the same purpose'. HS code 381119 is for 'Other' preparations within this category that do not fit into more specific subheadings (like those for lead compounds). Classification relies on the product's function and composition, ensuring it is a prepared additive for mineral oils or similar liquids, and not specifically covered elsewhere in the tariff schedule.
Which common trade agreements significantly impact the duty rates for HS code 381119, and where can I find this information?
Several trade agreements can significantly reduce or eliminate duties for HS code 381119. For instance, the USMCA (United States-Mexico-Canada Agreement) may offer preferential rates between these countries. Agreements like the EU's Economic Partnership Agreements (EPAs) or Free Trade Agreements (FTAs) with countries such as South Korea (KR) or Australia (AU) often provide duty-free access. Importers can find this information by consulting the official customs tariff schedule of the importing country, which typically lists preferential rates alongside the general (MFN) rate, or by using online tariff databases like the US International Trade Commission (USITC) Harmonized Tariff Schedule, the EU's TARIC database, or the UK's Trade Tariff.
