HS 731581 Other chain
Quick Answer: Other chain imported under HS 731581 enters the UK duty-free at 0.00%, the EU at 2.70% ad valorem, and the US at a rate of 4.4¢/kg or free, depending on specific product characteristics. This classification covers chains not specifically enumerated elsewhere in Chapter 73 of the Harmonized System, excluding welded link chain of iron or steel and roller chain. Importers should carefully review the specific subheadings within HS 731581 for each jurisdiction to determine the precise duty rate applicable to their goods. According to CustomTariffs data, understanding these nuances is crucial for accurate customs declarations and cost management.

How to Classify This HS Code?
What products does HS 731581 cover?
This subheading covers "other chain" not specified in preceding subheadings of HS 7315, which primarily deals with chains, chain wheels, and parts thereof, of iron or steel. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category encompasses chains made of iron or steel that do not fall under specific types like anchor chains, lifting chains, or conveyor chains. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this broad scope for chains of iron or steel not otherwise specified.
What falls outside HS 731581?
The following products are excluded from HS 731581: anchor chains and parts thereof (HS 7315.20), and other chains and parts thereof, specifically for lifting or mechanical handling (HS 7315.82). Chains made from materials other than iron or steel, such as plastic or aluminum, are also classified elsewhere. For instance, plastic chains would typically fall under Chapter 39, and aluminum chains under Chapter 76. Therefore, the material composition and specific intended use are critical for accurate exclusion.
What are common classification mistakes for HS 731581?
A common error is misclassifying specialized chains that have a specific function, such as those designed for snow chains or for use in specific industrial machinery, which might have their own more precise HS codes. For example, a chain specifically designed as a drive chain for a bicycle might be classified under a more specific heading if available, rather than the general "other chain" code. Adherence to General Interpretative Rule 3(a) and 3(b) of the Harmonized System is crucial to ensure the most specific and appropriate classification.
How should importers classify products under HS 731581?
The correct procedure for classifying products under HS 731581 involves a multi-step process. Importers and customs brokers must first identify the material composition of the chain (iron or steel). Next, they must determine its specific function and construction to ensure it is not covered by more specific subheadings within HS 7315 or other HS chapters. Consulting the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and reviewing explanatory notes from the WCO is essential for accurate classification.
How is the duty calculated for products under HS 731581?
A 100-meter coil of general-purpose steel chain, weighing 50 kilograms and declared at a customs value of $300 USD, would attract a US duty of $15.00. This is calculated using the USITC Harmonized Tariff Schedule's Most Favored Nation (MFN) rate of 5% ad valorem applied to the declared value ($300 USD × 0.05 = $15.00). If the chain were classified under a specific weight-based duty, the calculation would differ, but for this example, the ad valorem rate is applied.
Which trade agreements reduce duties for HS 731581?
Several free trade agreements may reduce the applicable duty rate for HS 731581, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer preferential rates, often Free, for eligible goods from designated developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and importing country's requirements.

FAQ
What are the typical import duty rates for HS code 731581, 'Other chain'?
The Most Favored Nation (MFN) duty rate for HS code 731581, 'Other chain', in the United States is 2.70% ad valorem. However, preferential rates may apply under various trade agreements. For instance, goods originating from Canada or Mexico under the United States-Mexico-Canada Agreement (USMCA) may be eligible for duty-free entry (0.00%). Always verify the specific origin of the goods and applicable trade agreements to determine the correct duty rate. Consult the US International Trade Commission (USITC) Harmonized Tariff Schedule for the most current rates.
How is the duty for HS code 731581 calculated, and can you provide an example?
The duty for HS code 731581 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared value of the imported goods. For example, if the MFN duty rate is 2.70% and you import 1,000 kilograms of chain valued at $5,000 USD, the duty would be calculated as follows: Duty = Value × Duty Rate = $5,000 × 2.70% = $135.00 USD. If a specific duty rate (e.g., per kilogram) is applicable, the calculation would be based on the quantity. Always ensure accurate valuation and classification to avoid discrepancies.
What are the key classification criteria for HS code 731581, 'Other chain'?
HS code 731581 falls under Chapter 73 of the Harmonized System, which covers articles of iron or steel. Specifically, heading 7315 covers ' . . . chain and parts thereof, of iron or steel'. Subheading 7315.81 is for 'Other chain'. This classification generally applies to chains made of iron or steel that are not specifically covered by other more precise subheadings within 7315, such as welded link chains (7315.11, 7315.12) or unlinked or unfinished chains (7315.82). The material composition (iron or steel) and construction (e.g., not specifically defined as block-link, stud-link, or other specialized types) are primary determinants. Refer to the WCO Harmonized System Explanatory Notes for detailed guidance.
What documentation is typically required for importing goods classified under HS code 731581?
Standard documentation for importing goods under HS code 731581 includes a commercial invoice detailing the value, quantity, and description of the chain; a packing list; and a bill of lading or air waybill. Depending on the origin and any claimed preferential duty rates, a Certificate of Origin may be required. Importers should also be prepared to provide product specifications or technical drawings if Customs requests further clarification on the chain's construction or material to verify its classification. Ensuring all documentation is accurate and complete is crucial for smooth customs clearance.
Which trade agreements commonly provide preferential duty rates for HS code 731581?
Several trade agreements can impact the duty rates for HS code 731581. In the United States, the United States-Mexico-Canada Agreement (USMCA) often provides duty-free entry (0.00%) for qualifying goods originating from Canada or Mexico. Other agreements, such as those with Australia or South Korea, might offer reduced rates. For importers in the European Union, the EU TARIC database would detail preferential rates under agreements with countries like Switzerland, Norway, or those in the European Economic Area (EEA). For the UK, the UK Trade Tariff provides similar information for its trade agreements. It is imperative for importers to verify the rules of origin for each specific trade agreement to claim preferential treatment.
