HS 840910 For aircraft engines
Quick Answer: Parts and accessories for aircraft engines imported under HS 840910 enter the UK duty-free, the EU at 1.70% ad valorem, and the US at 35% ad valorem under the MFN rate. This classification specifically covers parts and accessories designed for use with aircraft engines, excluding complete engines themselves. Importers should be aware of potential variations in specific subheadings within each jurisdiction that may affect the final duty rate. According to CustomTariffs data, careful attention to the precise nature of the part or accessory is crucial for accurate classification and compliance.

How to Classify This HS Code?
What products does HS 840910 cover?
This subheading covers parts and accessories specifically designed for use with aircraft engines, as defined by the World Customs Organization (WCO) Harmonized System Nomenclature. According to the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this includes components such as pistons, cylinders, crankshafts, and fuel injection systems that are exclusively or principally intended for incorporation into or use with engines of heading 8803, which pertains to parts of aircraft. The key criterion is their specific application to aircraft propulsion systems.
What falls outside HS 840910?
The following products are excluded from HS 840910: general-purpose engine parts not specifically designed for aircraft, such as those used in automobiles or industrial machinery, even if they share similar design principles. Components that are not exclusively or principally for aircraft engines, like general fasteners or electrical wiring harnesses, are also excluded. For instance, a universal spark plug or a standard bearing would likely be classified under different headings based on their general application rather than their specific use in an aircraft engine.
What are common classification mistakes for HS 840910?
A common error is classifying general-purpose engine components that are not exclusively or principally intended for aircraft engines under this subheading. This often occurs when parts are interchangeable with those used in other types of engines. According to General Interpretative Rule 1 (GIR 1) of the Harmonized System, classification is determined by the terms of the headings and any relative section or chapter notes. Misinterpreting "for aircraft engines" to include any engine part that *could* be adapted for aircraft use, rather than parts *specifically designed* for that purpose, leads to incorrect classification.
How should importers classify products under HS 840910?
The correct procedure for classifying products under HS 840910 involves a thorough examination of the product's design, intended use, and the manufacturer's specifications. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and cross-reference with WCO Explanatory Notes. If a product is explicitly listed as a part for aircraft engines and cannot be readily used for other purposes, it should be classified here. If ambiguity exists, seeking a binding ruling from customs authorities is advisable.
How is the duty calculated for products under HS 840910?
A specific aircraft engine turbine blade, weighing 0.5 kg and declared at a customs value of $5,000 USD, would attract a US duty of $250.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, as published in the USITC Harmonized Tariff Schedule (HTS) for a similar component. The calculation is: 5.0% × $5,000 USD = $250.00. It is crucial to verify the exact rate for the specific part in the current HTS.
Which trade agreements reduce duties for HS 840910?
Several free trade agreements may reduce the applicable duty rate for HS 840910, including the United States-Mexico-Canada Agreement (USMCA) which can result in a Free duty rate for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for qualifying goods from certain developing countries. Documentation required typically includes a self-certified origin statement for USMCA, or a GSP Form A for GSP beneficiaries, to claim preferential treatment.

FAQ
What are the typical import duty rates for HS code 840910, 'Parts of engines of heading 8407 or 8408, for aircraft'?
The import duty rates for HS code 840910 vary significantly by country. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) rate is 0.00%. However, preferential rates under trade agreements may apply. The EU's TARIC system and the UK's Trade Tariff also provide specific rates, which can be found by consulting their respective databases. It is crucial to check the specific tariff schedule of the importing country at the time of importation.
How is HS code 840910 classified, and what criteria determine if a part falls under this code?
HS code 840910 specifically covers 'Parts of engines of heading 8407 or 8408, for aircraft'. This means the parts must be identifiable as being exclusively or principally used with aircraft engines falling under headings 8407 (spark-ignition internal combustion piston engines) or 8408 (compression-ignition internal combustion piston engines). The classification relies on the intended use and design of the part. For instance, specialized turbine blades, fuel injectors, or ignition systems designed solely for aircraft engines would fall under this code. General-purpose engine parts not specific to aircraft engines would be classified elsewhere.
What documentation is typically required for importing goods classified under HS code 840910?
When importing parts for aircraft engines under HS code 840910, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Additionally, a certificate of origin may be necessary, especially if preferential duty rates are claimed under a trade agreement. Depending on the importing country's regulations and the specific nature of the aircraft parts, additional certifications related to airworthiness, safety standards, or manufacturer's declarations might be requested by customs authorities to ensure compliance with aviation regulations.
Which common trade agreements might offer preferential duty rates for HS code 840910, and how can importers verify eligibility?
Several trade agreements can impact duty rates for HS code 840910. For instance, the United States has Free Trade Agreements (FTAs) with countries like Canada and Mexico (USMCA), and previously with South Korea (KORUS FTA), which may offer reduced or zero duty rates on eligible aircraft parts. The EU has numerous trade agreements with partner countries, and the UK has its own set of trade deals post-Brexit. To verify eligibility, importers and customs brokers must consult the specific text of the relevant trade agreement and the importing country's tariff schedule. Key requirements often include meeting rules of origin, providing a valid certificate of origin, and ensuring the goods are directly shipped from the beneficiary country.
How is the import duty for HS code 840910 calculated, and can you provide an example?
The calculation of import duty depends on the duty rate applied by the importing country's customs authority. Duties can be ad valorem (a percentage of the value of the goods) or specific (a fixed amount per unit). For HS code 840910, let's assume an importing country applies a 1.70% ad valorem duty rate. If an importer brings in aircraft engine parts valued at $100,000 USD, the duty calculation would be: Duty = Value of Goods × Duty Rate. Therefore, Duty = $100,000 × 1.70% = $1,700. Importers must ensure the declared value is accurate and compliant with customs valuation rules.
