How to Classify This HS Code?
What products does HS 731590 cover?
This subheading covers "Other parts" of chains and parts thereof, not elsewhere specified or included within heading 7315. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category is for components that are not specifically enumerated in the preceding subheadings of 7315, which detail various types of chains and their specific parts. For instance, the US International Trade Administration (USITA) and the EU's TARIC database confirm that this residual category applies to miscellaneous iron or steel parts that are integral to the functioning of chains but do not fit into more specific classifications.
What falls outside HS 731590?
The following products are excluded from HS 731590: complete chains of iron or steel (classified under 7315.11 to 7315.19 for roller and conveyor chains, and 7315.81 to 7315.89 for other chains), and specific parts of chains that are explicitly covered in other subheadings of 7315, such as pins, rollers, and side plates for roller chains. Additionally, finished articles incorporating chain parts, like lifting equipment or machinery components, would be classified according to their primary function or material, not as mere parts under this subheading.
What are common classification mistakes for HS 731590?
A common error is misclassifying components that, while appearing to be simple "other parts," are actually specific to a particular type of chain and therefore belong to a more precise subheading within 7315. For example, a specialized link designed exclusively for a conveyor chain might be mistakenly entered here. Adherence to General Interpretative Rule 3(b) of the Harmonized System, which addresses goods consisting of different materials or components, is crucial to ensure the correct classification based on essential character.
How should importers classify products under HS 731590?
The correct procedure for classifying products under HS 731590 involves a thorough examination of the product's specific characteristics and its intended use in relation to the broader scope of heading 7315. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC Harmonized Tariff Schedule (HTS) or the EU's TARIC database, and compare the product's description and function against the notes and subheadings of 7315. If the part is not specifically described elsewhere in 7315, and it is indeed a part of an iron or steel chain, then 7315.90 is the appropriate classification.
How is the duty calculated for products under HS 731590?
A shipment of 500 kilograms of specialized steel connecting links for industrial chains, declared at a customs value of $2,500 USD, would attract a US duty. Assuming a Most Favored Nation (MFN) duty rate of 3.5% ad valorem, the duty would be $87.50 USD ($2,500 USD × 0.035). This calculation is based on the ad valorem rate applied to the declared customs value, as published in the USITC Harmonized Tariff Schedule for subheading 7315.90.0000.
Which trade agreements reduce duties for HS 731590?
Several free trade agreements may reduce the applicable duty rate for HS 731590, including the United States-Mexico-Canada Agreement (USMCA), which can provide for a duty rate of Free for qualifying originating goods from Canada and Mexico. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for qualifying goods from certain developing countries. To claim preference under USMCA, a valid Certificate of Origin or a self-certified origin statement is typically required, while GSP often necessitates a Form A.

FAQ
What are the typical import duty rates for HS code 731590, 'Other parts' of iron or steel chain, etc.?
The Most Favored Nation (MFN) duty rate for HS code 731590 can vary. For example, under the US tariff schedule, the MFN rate is 2.70%. However, preferential rates are available for certain trading partners. For instance, goods from Australia (AU), Canada (CA), Mexico (MX), or South Korea (KR) may enter duty-free under specific trade agreements. Always consult the latest tariff schedule for the importing country to confirm applicable rates.
How is the import duty for HS 731590 calculated, and can you provide an example?
The duty calculation depends on whether the rate is ad valorem (a percentage of the value) or specific (a fixed amount per unit). For HS 731590, the US MFN rate is 2.70% ad valorem. If an importer brings in parts valued at $10,000, the duty would be calculated as: $10,000 (value) × 0.0270 (duty rate) = $270.00. If the duty were specific, for example, $0.50 per kilogram, and the shipment weighed 500 kg, the duty would be 500 kg × $0.50/kg = $250.00. Always verify the basis of duty calculation (ad valorem, specific, or compound) from the official tariff.
What are the classification criteria for classifying goods under HS code 731590 ('Other parts')?
HS code 731590 is a residual category for parts of articles within heading 73.15, which covers 'Iron or steel chain and parts thereof'. To classify under 731590, the item must be identifiable as a component part of an article described in heading 73.15 (e.g., parts of anchor chains, parts of conveyor or traction chains, parts of roller or caterpillar chains) and not specifically classified under a more precise subheading within 73.15. The WCO's Explanatory Notes to the Harmonized System provide further guidance on the scope of heading 73.15 and its subheadings.
Which common trade agreements offer preferential duty rates for HS code 731590, and what documentation is typically required?
Several trade agreements can provide preferential duty rates for HS code 731590. For example, the United States has agreements with countries like South Korea (KORUS FTA), Australia (AUSFTA), and Chile (USCFTA) that may offer reduced or zero duty rates. To claim these preferences, importers typically need to provide a Certificate of Origin or a declaration of origin from the exporter, demonstrating that the goods meet the rules of origin stipulated in the respective trade agreement. Always check the specific requirements of the relevant trade agreement and the importing country's customs regulations.
Are there any specific documentation requirements beyond a commercial invoice and packing list for importing goods classified under HS 731590?
While a commercial invoice, packing list, and bill of lading are standard import documents, additional requirements for HS 731590 may arise depending on the importing country and the specific nature of the 'parts'. For instance, if the parts are for use in machinery subject to specific safety or technical standards, compliance certificates or declarations might be necessary. If claiming preferential duty rates under a Free Trade Agreement (FTA), a valid Certificate of Origin is crucial. It is advisable for importers and customs brokers to consult the importing country's customs authority or the relevant trade agreement for a comprehensive list of required documentation.
