How to Classify This HS Code?
What products does HS 732510 cover?
This subheading covers articles of iron or steel, cast, of non-malleable cast iron, not elsewhere specified or included. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this includes cast iron articles that are brittle and cannot be deformed without breaking, such as certain types of pump casings, machine parts, and decorative items. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database further define this category by excluding malleable cast iron products and those specifically covered in other headings within Chapter 73.
What falls outside HS 732510?
The following products are excluded from HS 732510: articles of malleable cast iron, which are classified under HS 732599; finished articles of cast iron that are specifically enumerated in other headings, such as cast iron pipes and fittings (HS 7303); cast iron radiators and parts thereof (HS 7322); and cast iron cooking appliances (HS 7321). Additionally, articles of wrought iron or steel are not included, as they are classified under different chapters or headings.
What are common classification mistakes for HS 732510?
A common error is misinterpreting "non-malleable cast iron" and incorrectly classifying malleable cast iron products under this subheading. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the heading and any relative section or chapter notes. Importers may also mistakenly classify finished goods made from cast iron, such as machinery components, if they are specifically covered by a more precise heading, overlooking the principle of specific heading precedence.
How should importers classify products under HS 732510?
The correct procedure for classifying products under HS 732510 involves a thorough examination of the product's material composition and manufacturing process. Importers and customs brokers must verify that the article is indeed made of non-malleable cast iron and is not specifically listed in a more precise heading. Consulting the official tariff schedules of the importing country, such as the USITC HTS or the EU TARIC, and referencing the WCO HS Explanatory Notes are crucial steps to ensure accurate classification.
How is the duty calculated for products under HS 732510?
A cast iron pump housing weighing 15 kg and declared at a customs value of $100 USD would attract a US duty of $7.50. This is calculated using the Most Favored Nation (MFN) duty rate of 5% ad valorem applied to the declared value ($100 USD × 0.05 = $5.00), plus a specific duty of $0.17 per kg ($0.17/kg × 15 kg = $2.50), totaling $7.50. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule for HS code 732510.
Which trade agreements reduce duties for HS 732510?
Several free trade agreements may reduce the applicable duty rate for HS 732510, 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. The Generalized System of Preferences (GSP) may also offer reduced or Free duty rates for eligible products 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 jurisdiction and agreement.

FAQ
What are the typical import duty rates for HS code 732510 (Of non-malleable cast iron) into the United States, European Union, and the United Kingdom?
For imports into the United States, the Most Favored Nation (MFN) duty rate for HS code 732510 is typically 0.00% ad valorem. In the European Union, the TARIC system often shows a 1.70% ad valorem duty rate for goods originating from countries without a preferential trade agreement. The UK Trade Tariff also indicates a 1.70% ad valorem duty rate for goods not covered by preferential agreements. It is crucial for importers to verify the specific rate based on the country of origin and any applicable trade agreements, as these rates can change. Always consult the latest official tariff schedules of the importing country.
How is 'non-malleable cast iron' defined for HS classification under 732510, and what distinguishes it from malleable cast iron?
For HS classification purposes under 732510, 'non-malleable cast iron' refers to cast iron that cannot be readily deformed or worked without fracturing. This is primarily determined by its microstructure and mechanical properties. Unlike malleable cast iron, which undergoes a specific heat treatment process to increase its ductility and toughness, non-malleable cast iron (such as grey cast iron or white cast iron) is generally more brittle. Importers should ensure their product specifications and any accompanying technical documentation clearly indicate the type of cast iron and its properties to support the classification.
What documentation is typically required when importing goods classified under HS code 732510?
When importing goods under HS code 732510, standard customs documentation is required. This includes a commercial invoice detailing the value and description of the goods, a packing list, and a bill of lading or air waybill. Crucially, importers should be prepared to provide evidence supporting the classification, such as technical specifications, material test reports, or manufacturer declarations that confirm the item is made of non-malleable cast iron. For goods claiming preferential duty rates under a trade agreement, a certificate of origin is usually mandatory.
How is the import duty calculated for HS 732510 if the duty rate is 1.70% ad valorem and the declared value of the shipment is $10,000 USD?
The duty calculation for HS code 732510, when subject to an ad valorem rate, is based on the customs value of the imported goods. If the duty rate is 1.70% ad valorem and the declared value of the shipment is $10,000 USD, the import duty would be calculated as follows: Duty = Declared Value × Duty Rate. In this example: Duty = $10,000 USD × 1.70% = $10,000 USD × 0.0170 = $170 USD. Importers and customs brokers must ensure the declared value is accurate and in compliance with the importing country's valuation rules.
Do trade agreements like the USMCA or EU Free Trade Agreements offer preferential duty rates for HS code 732510?
Preferential duty rates for HS code 732510 may be available under various trade agreements, depending on the country of origin and the importing country. For instance, goods originating from Canada or Mexico and meeting the rules of origin under the United States-Mexico-Canada Agreement (USMCA) may qualify for duty-free entry into the United States. Similarly, the European Union has numerous Free Trade Agreements (FTAs) with third countries that could reduce or eliminate duties on non-malleable cast iron products if they originate from a partner country and meet the relevant rules of origin. Importers must consult the specific provisions of applicable trade agreements and obtain the necessary proof of origin to claim preferential treatment.
