How to Classify This HS Code?
What products does HS 731815 cover?
This subheading covers screws and bolts, made of iron or steel, that are not specifically covered by other subheadings within heading 7318. This includes threaded fasteners with external screw threads, whether or not they are supplied with washers or nuts. The World Customs Organization's Explanatory Notes to the Harmonized System (WCO HS Explanatory Notes) clarify that this category encompasses a wide variety of common threaded fasteners, excluding those with specific features like self-tapping threads or those designed for particular applications like wood screws or machine screws with specific heads. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database provide further detail on the scope, generally including standard machine screws and bolts.
What falls outside HS 731815?
The following products are excluded from HS 731815: screws and bolts specifically designed for wood (HS 731812), self-tapping screws and bolts (HS 731814), and screws and bolts with heads of precious metal or metal clad with precious metal (HS 731816). Also excluded are threaded articles of plastics or other non-metallic materials, as well as nuts and washers when imported separately, which are classified under other subheadings within 7318 or in different chapters depending on their material. For example, nuts for screws and bolts of iron or steel are typically found under HS 731816.
What are common classification mistakes for HS 731815?
A common error is misclassifying specialized screws or bolts that have specific features, such as those designed for particular industries or applications, under this general subheading. For instance, screws with unique thread forms or those intended for use in specialized machinery might warrant a more specific classification. General Rule of Interpretation (GRI) 3(a) of the Harmonized System, which states that the heading providing the most specific description shall be preferred, is often overlooked. Importers may also incorrectly classify items that are not primarily threaded fasteners, such as rivets or pins.
How should importers classify products under HS 731815?
The correct procedure for classifying products under HS 731815 involves a thorough examination of the product's physical characteristics and intended use, referencing the WCO HS Explanatory Notes and national tariff schedules like the USITC HTS or EU TARIC. Importers and customs brokers must determine if the item is a screw or bolt made of iron or steel, if it possesses external screw threads, and if it is not specifically provided for in more precise subheadings. Verification of the presence or absence of nuts or washers, and their relation to the primary fastener, is also crucial for accurate classification.
How is the duty calculated for products under HS 731815?
A shipment of 1,000 kg of M8 steel bolts, declared at a customs value of $5,000 USD, would attract a US duty of $500.00. This is calculated using the Most Favored Nation (MFN) duty rate of 10% ad valorem, applied to the declared customs value. The calculation is: 10% × $5,000 USD = $500.00. This rate is published in the USITC Harmonized Tariff Schedule (HTS) under subheading 731815.2000 for bolts other than those of stainless steel.
Which trade agreements reduce duties for HS 731815?
Several free trade agreements may reduce the applicable duty rate for HS 731815, including the United States-Mexico-Canada Agreement (USMCA), which can provide for duty-free entry for qualifying goods originating from Canada or Mexico. The EU's Generalized Scheme of Preferences (GSP) may offer reduced or free duties for goods from certain developing countries. Documentation required to claim preference under USMCA typically involves a certification of origin, while for GSP, a GSP Form A may be necessary, depending on the specific origin country and the importing jurisdiction's requirements.

FAQ
What are the typical import duty rates for HS code 731815 in major markets like the US, EU, and UK?
For HS code 731815, 'Other screws and bolts, whether or not with their nuts or washers', duty rates vary by country. In the United States, the Most Favored Nation (MFN) duty rate is typically 3.70% ad valorem. In the European Union, under the TARIC system, the rate is often 2.7% ad valorem, though specific origin and trade agreements can modify this. The UK Trade Tariff also generally lists a rate of 3.70% ad valorem for goods from non-preferential sources. It is crucial to consult the specific tariff schedule of the importing country for the most accurate and up-to-date rates, as well as any applicable trade agreement preferences.
How is the duty calculated for HS code 731815, and can you provide an example?
The duty for HS code 731815 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if screws classified under 731815 are imported into the United States with a declared customs value of $10,000 USD, and the MFN duty rate is 3.70%, the import duty would be calculated as: $10,000 (Customs Value) × 0.0370 (Duty Rate) = $370.00 USD. Some countries may also apply specific duties based on weight (e.g., per kilogram), which would be calculated differently. Always verify the duty basis (ad valorem, specific, or a combination) with the relevant customs authority.
What criteria distinguish HS code 731815 from other fastener classifications, and what documentation is needed?
HS code 731815 covers screws and bolts made of iron or steel that do not fall under more specific subheadings within 7318. Key distinguishing factors include the material (iron or steel), the presence or absence of nuts or washers, and whether they are specifically designed for particular uses (e.g., wood screws, self-tapping screws, or those with specialized heads or threads that might warrant a different classification). Documentation typically required for import includes a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin if preferential duty rates are claimed. For fasteners, detailed specifications (material grade, dimensions, thread type, head type) on the commercial invoice or a technical datasheet can be essential for customs verification.
Which common trade agreements might offer preferential duty rates for HS code 731815, and how can importers benefit?
Importers can benefit from preferential duty rates under various trade agreements. For instance, goods originating from countries that are part of the USMCA (United States-Mexico-Canada Agreement) may have reduced or zero duty rates for certain fasteners, provided they meet the rules of origin. Similarly, the EU has numerous Free Trade Agreements (FTAs) with countries worldwide, which can significantly lower or eliminate duties on goods like screws and bolts from those partner nations. To benefit, importers must obtain a valid Certificate of Origin from the exporter, demonstrating that the goods meet the preferential rules of origin stipulated in the relevant trade agreement. This documentation is critical for claiming reduced duties at the time of import.
