How to Classify This HS Code?
What products does HS 731811 cover?
This subheading covers screws and bolts, with or without their nuts or washers, made of iron or steel, specifically those that are threaded. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes items like machine screws, wood screws, and coach screws, provided they possess external screw threads. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system align with this definition, emphasizing the threaded nature of the article as the primary classification criterion.
What falls outside HS 731811?
The following products are excluded from HS 731811: threaded articles made of materials other than iron or steel, such as brass or aluminum, which would be classified under different headings. Also excluded are unthreaded fasteners, like nails or rivets, and articles that, while threaded, are primarily considered parts of machinery or vehicles and are specifically provided for elsewhere in the tariff schedule. For instance, specialized threaded components for engines are typically classified under machinery headings.
What are common classification mistakes for HS 731811?
A common error is misclassifying threaded articles based solely on their intended use rather than their material and construction. For example, a threaded bolt made of stainless steel, while functionally similar to one made of carbon steel, would be classified under a different heading (e.g., 731819 if not otherwise specified). Adherence to General Rule of Interpretation (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes, is crucial to avoid such mistakes.
How should importers classify products under HS 731811?
The correct procedure for classifying products under HS 731811 involves a systematic approach. Importers and customs brokers should first identify the material composition (iron or steel) and confirm the presence of external screw threads. Next, they must consult the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, to verify that the product meets the specific description of subheading 731811. Cross-referencing with WCO Explanatory Notes can provide further clarity on the scope of the subheading.
How is the duty calculated for products under HS 731811?
A shipment of 1,000 carbon steel wood screws weighing 5 kilograms and declared at a customs value of $50 USD would attract a US duty of $0.25. This is calculated using the USITC Harmonized Tariff Schedule's Most Favored Nation (MFN) rate of 4.9% ad valorem applied to the declared value ($50 USD × 0.049 = $2.45). Note: For fasteners, duty can also be assessed on weight. If the duty on weight were higher, that would apply. For example, if the rate was $0.05 per kg, the duty would be $0.25 (5 kg × $0.05/kg).
Which trade agreements reduce duties for HS 731811?
Several free trade agreements may reduce the applicable duty rate for HS 731811, 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. To claim this preference, a valid USMCA certification of origin is required. Additionally, goods originating from countries benefiting from the EU's Generalized Scheme of Preferences (GSP) may also receive reduced or Free duty rates, often requiring a EUR.1 movement certificate or a self-certified origin declaration.

How is the duty calculated for HS code 731811?
The duty for HS code 731811 is typically calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. For example, if you import 10,000 units of screws valued at $0.50 each, the total value is $5,000. With an MFN duty rate of 3.70%, the duty would be calculated as: $5,000 (value) × 0.0370 (duty rate) = $185.00. This calculation assumes no other duties or taxes apply.
What are the classification criteria for HS code 731811?
HS code 731811 specifically covers screws and bolts, with or without their nuts or washers, made of iron or steel, which are threaded or tapped. Crucially, these fasteners must be of a kind used in motor vehicles. This excludes common wood screws and machine screws/bolts unless they meet the specific 'used in motor vehicles' criterion. The presence or absence of nuts or washers, or if they are pre-assembled, does not change the classification as long as the item is threaded or tapped and intended for automotive use. Refer to Chapter 73, Section XV of the Harmonized System Nomenclature for detailed interpretive notes.
Which trade agreements offer preferential duty rates for HS code 731811?
Several trade agreements can provide preferential duty rates for goods classified under HS code 731811. For instance, under the Australia-United States Free Trade Agreement (AUSFTA), goods originating from Australia may enter the U.S. duty-free. Other agreements, such as those with South Korea (KOR-US FTA) or Chile (CL), may also offer reduced or zero duty rates. Importers must ensure they have a valid Certificate of Origin to claim these preferential treatments. Consult the specific trade agreement texts and the USITC Harmonized Tariff Schedule for the most current information.
Are there specific documentation requirements for importing goods under HS code 731811?
While standard import documentation such as a commercial invoice, packing list, and bill of lading are always required, specific documentation for HS code 731811 may depend on the country of import and any claimed preferential duty rates. For imports into the United States, if claiming preferential treatment under a Free Trade Agreement (e.g., from Australia or South Korea), a Certificate of Origin is mandatory. Furthermore, if the goods are specifically designated for automotive use, the importer may need to provide documentation or declarations to substantiate this intended use, especially if specific automotive-related regulations or standards are in place. Always consult the customs regulations of the importing country and your customs broker for precise requirements.
