How to Classify This HS Code?
What products does HS 840690 cover?
This subheading covers "Parts" for internal combustion piston engines, as defined by the World Customs Organization's Harmonized System (WCO HS) nomenclature. Specifically, it encompasses components designed exclusively for use with engines of heading 8406, which includes spark-ignition internal combustion piston engines. According to the US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this includes items such as pistons, piston rings, connecting rods, crankshafts, camshafts, valves, and cylinder liners, provided they are not parts of engines of other headings. The UK Trade Tariff also aligns with this definition for parts specific to spark-ignition engines.
What falls outside HS 840690?
The following products are excluded from HS 840690: complete engines of heading 8406, parts for diesel or semi-diesel engines (classified under heading 8407 or 8408), and general-purpose parts that could be used with engines of various types or other machinery, such as fasteners, bearings, or electrical components not specifically designed for 8406 engines. For instance, a universal bolt or a standard ball bearing would not be classified here, even if it could be fitted to an 8406 engine. Parts for gas turbines (heading 8406) are also excluded.
What are common classification mistakes for HS 840690?
A common error is misclassifying parts that are not exclusively designed for spark-ignition internal combustion piston engines. General Rule of Interpretation (GRI) 1 of the Harmonized System mandates that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers may mistakenly classify parts for diesel engines (heading 8408) under 840690, or parts that are common to multiple types of machinery. Another mistake is classifying complete engines or sub-assemblies that constitute a significant portion of an engine as mere parts.
How should importers classify products under HS 840690?
The correct procedure for classifying products under HS 840690 involves a thorough examination of the item's design, function, and intended use. Importers and customs brokers must confirm that the part is specifically manufactured for an internal combustion piston engine of the spark-ignition type (heading 8406). Consulting the official WCO HS Explanatory Notes, the USITC HTS, EU TARIC, or the UK Trade Tariff is crucial. If the part is a component of a diesel engine or a general-purpose item, it should be classified elsewhere. Verification of any accompanying technical specifications or manufacturer declarations is also recommended.
How is the duty calculated for products under HS 840690?
A specific piston ring set for a gasoline engine, weighing 0.5 kg and declared at a customs value of $50 USD, would attract a US duty of $3.50. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared value: 7.0% × $50 USD = $3.50. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8406.90.0000. Note that specific parts might have different rates, and the ad valorem rate is applied to the customs value.
Which trade agreements reduce duties for HS 840690?
Several free trade agreements may reduce the applicable duty rate for HS 840690, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, qualifying parts originating from Canada or Mexico can enter the United States duty-free. For example, a piston ring set manufactured in Mexico and meeting the rules of origin would be eligible for a 0% duty rate. To claim this preference, a self-certified origin statement on the invoice or a separate declaration is typically required. Other agreements may offer reduced rates for specific countries, but USMCA is a prominent example for North American trade.

FAQ
What are the typical import duty rates for HS code 840690 (Parts of compression-ignition internal combustion piston engines)?
The Most Favored Nation (MFN) duty rate for HS code 840690 is generally 2.70% ad valorem. However, preferential duty rates can significantly reduce or eliminate this. For example, under the Free Trade Agreement between the United States and Australia (AU), the duty rate is Free. Importers should always verify the specific rate applicable based on the country of origin and any relevant trade agreements. Refer to the USITC Harmonized Tariff Schedule for the most current MFN and preferential rates.
How is the import duty for HS code 840690 calculated, and can you provide an example?
The duty for HS code 840690 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the imported goods. For instance, if a shipment of engine parts classified under 840690 has a declared customs value of $10,000 and the applicable MFN duty rate is 2.70%, the calculated duty would be $10,000 * 0.0270 = $270.00. It's crucial to ensure the customs value is correctly determined according to WTO valuation rules.
What documentation is typically required when importing parts under HS code 840690?
When importing parts classified under HS code 840690, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the origin and specific nature of the parts, a Certificate of Origin may be necessary to claim preferential duty rates under trade agreements. Manufacturers' specifications or technical data sheets might also be requested by customs authorities to verify the classification and intended use of the parts.
Which common trade agreements offer preferential duty rates for HS code 840690?
Several trade agreements can provide preferential duty rates for parts of compression-ignition internal combustion piston engines (HS 840690). Examples include agreements with countries like Australia (AU), Chile (CL), South Korea (KR), and Singapore (SG), which often grant Free (0.00%) duty rates under specific conditions and rules of origin. Importers should consult the relevant trade agreement text and the official tariff database (e.g., USITC HTS) to confirm eligibility and any specific requirements for claiming these benefits.
What are the classification criteria for determining if a part falls under HS code 840690?
HS code 840690 covers 'Parts' specifically for compression-ignition internal combustion piston engines (engines of heading 8407 or 8408, but excluding those of heading 8407). This means the parts must be identifiable as solely or principally used with such engines, which are typically diesel engines. Examples include engine blocks, pistons, crankshafts, cylinder heads, fuel injectors, and gaskets specifically designed for these engines. Parts for spark-ignition engines (like gasoline engines) would fall under a different HS code. Always refer to the Chapter and Heading notes of Section XVI of the Harmonized System for definitive classification guidance.
