How to Classify This HS Code?
What products does HS 841510 cover?
This subheading covers air conditioning machines, comprising a motor-driven fan and elements for altering the temperature and humidity, of a kind designed to be fixed to a window, wall, ceiling or floor, whether self-contained or "split-system." According to the WCO Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, this includes units where the cooling/heating components are integrated into a single casing or separated into indoor and outdoor units connected by refrigerant lines.
What falls outside HS 841510?
The following products are excluded from HS 841510: air conditioning machines not designed for fixed installation, such as portable units (typically classified under 8415.90), and machines that only ventilate or circulate air without altering temperature or humidity (classified under 8414.59). Additionally, central air conditioning systems with separate components not designed for direct window, wall, ceiling, or floor mounting, or those primarily for industrial process cooling, are generally classified elsewhere, often under 8415.80.
What are common classification mistakes for HS 841510?
A common error is misinterpreting the "self-contained" versus "split-system" distinction, leading to incorrect classification. For instance, classifying a portable air conditioner with a window exhaust kit under this subheading is incorrect, as it is not designed for fixed installation. Adherence to General Rule of Interpretation (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial. Misclassifying units that are primarily heaters with a secondary cooling function can also occur.
How should importers classify products under HS 841510?
The correct procedure for classifying products under HS 841510 involves a thorough examination of the product's design and intended installation method. Importers and customs brokers must verify if the unit is designed for fixed installation into a window, wall, ceiling, or floor. They should also confirm if it is a self-contained unit or a split-system with connected indoor and outdoor components. Consulting the specific product's technical specifications and the relevant tariff schedule's chapter and heading notes is essential for accurate classification.
How is the duty calculated for products under HS 841510?
A 10,000 BTU window air conditioner declared at a customs value of $300 USD would attract a US duty of $21.00. This is calculated using the Most Favored Nation (MFN) rate of 7.0% ad valorem, as published in the USITC Harmonized Tariff Schedule (HTSUS 8415.10.8000). The calculation is: 7.0% × $300 = $21.00. This rate applies to goods from countries not covered by preferential trade agreements or specific exclusions.
Which trade agreements reduce duties for HS 841510?
Several free trade agreements may reduce the applicable duty rate for HS 841510, 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 EU-UK Trade and Cooperation Agreement also offers preferential rates, potentially Free, for eligible goods originating from the UK into the EU, or vice versa. Documentation required typically includes a USMCA Certificate of Origin for North American trade or an EUR.1 movement certificate for EU/UK trade, or a self-certified origin statement depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 841510 (air conditioning machines, window/wall/ceiling/floor mounted, self-contained or split-system)?
The Most Favored Nation (MFN) duty rate for HS code 841510 generally falls around 2.00% to 3.5% ad valorem, depending on the specific importing country's tariff schedule. For example, under the US Harmonized Tariff Schedule (HTS), the general rate is 2.00% ad valorem. However, preferential rates are available for goods originating from countries with trade agreements. For instance, goods from Australia (AU), Canada (CA), Mexico (MX), or South Korea (KR) might benefit from reduced or free entry under specific trade pacts. Always consult the latest tariff schedule of the importing country for precise rates and applicable trade agreements.
How is the import duty for HS 841510 calculated? Can you provide an example?
The duty for HS code 841510 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if an air conditioning unit classified under 841510 has a customs value of $500 and the MFN duty rate is 2.00%, the import duty would be calculated as: $500 (customs value) × 0.02 (duty rate) = $10.00. Some countries may also apply specific duties based on quantity (e.g., per unit), so it's crucial to check the specific tariff line for any such additional charges.
What are the key classification criteria for HS code 841510?
HS code 841510 covers air conditioning machines designed for specific installation locations: fixed to a window, wall, ceiling, or floor. The machines can be either 'self-contained' (all components in a single unit) or 'split-system' (comprising an indoor and an outdoor unit connected by refrigerant lines). Crucially, the machine must be designed for cooling and, if applicable, heating air. Units not designed for fixed installation, or those that are primarily dehumidifiers or purifiers with incidental cooling functions, may fall under different HS codes.
What documentation is typically required when importing goods under HS code 841510?
Standard import documentation for HS code 841510 includes a commercial invoice detailing the value and description of the goods, a packing list, and a bill of lading or air waybill. Depending on the importing country and the origin of the goods, a Certificate of Origin may be required to claim preferential duty rates under trade agreements. Importers should also be prepared to provide product specifications or technical datasheets to substantiate the classification. Compliance with any applicable safety and energy efficiency standards (e.g., ETL, UL, CE markings) is also essential and may require specific declarations or certifications.
Which common trade agreements offer preferential duty rates for HS code 841510?
Several trade agreements can provide preferential duty rates for goods classified under HS 841510. For imports into the United States, the USMCA (United States-Mexico-Canada Agreement) may offer reduced or zero duties for qualifying goods from Canada and Mexico. The CARES Act also provides preferential treatment for goods from certain countries. For imports into the European Union, the EU's network of Free Trade Agreements (FTAs) with countries like South Korea, Japan, or Canada can reduce or eliminate duties. The UK also has its own set of FTAs post-Brexit. It is imperative for importers to verify the specific rules of origin and eligibility under the relevant trade agreement for the exporting country to benefit from these preferential rates.
