How to Classify This HS Code?
What products does HS 731813 cover?
This subheading covers screw hooks and screw rings, which are threaded fasteners designed for attachment to surfaces to provide a point for hanging or securing items. According to the World Customs Organization (WCO) Harmonized System Nomenclature, these items are typically made of iron or steel and feature a threaded shank that is screwed into a material, with a hook or loop at the other end. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, generally including items like eye screws and hook screws used in construction, DIY, and general hardware applications.
What falls outside HS 731813?
The following products are excluded from HS 731813: plain screw eyes or screw rings that do not have a hook or loop formation, and threaded bolts or screws without a hook or ring. Also excluded are items that are welded or otherwise permanently attached to other articles, or those with specialized functions not related to simple hanging or securing. For instance, machine screws, wood screws, and lag screws without the characteristic hook or ring are classified under other subheadings within heading 7318, and items like carabiner clips, which are not screwed in, fall under different headings entirely.
What are common classification mistakes for HS 731813?
A common error is misclassifying items that resemble screw hooks or rings but have a different primary function or construction. For example, a simple threaded stud without a hook or ring, or a screw with a closed loop that is intended for structural fastening rather than hanging, might be incorrectly entered under 731813. This often stems from not adhering to the General Rules for the Interpretation of the Harmonized System (GRI), particularly GRI 1, which prioritizes the Section and Chapter Notes and the headings' terms for classification. The specific shape and intended use are critical differentiators.
How should importers classify products under HS 731813?
The correct procedure for classifying products under HS 731813 involves a detailed examination of the product's physical characteristics and intended use. Importers and customs brokers must first consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and cross-reference with the WCO HS Nomenclature. Key considerations include verifying that the item is a screw with a hook or ring formation, made of iron or steel, and intended for hanging or securing. Comparing the product against descriptive notes and examples within the tariff schedule is crucial.
How is the duty calculated for products under HS 731813?
A shipment of 1,000 steel screw hooks, each weighing approximately 0.05 kg, with a total declared customs value of $200 USD, would attract a US duty. Assuming a Most Favored Nation (MFN) duty rate of 3.5% ad valorem as published in the USITC Harmonized Tariff Schedule for HS 731813, the duty would be calculated as 3.5% of $200 USD, resulting in a duty amount of $7.00 USD. This calculation demonstrates the application of the ad valorem rate based on the declared value of the goods.
Which trade agreements reduce duties for HS 731813?
Several free trade agreements may reduce the applicable duty rate for HS 731813, 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) also offers reduced or free duties for originating goods from certain developing countries. To claim these preferential rates, importers typically need to provide a self-certified origin statement for USMCA or a EUR.1 movement certificate for EU preferences, depending on the specific agreement and origin country.

FAQ
What are the import duty rates for HS code 731813 (screw hooks and screw rings) into the United States?
For imports into the United States, HS code 731813.0000 generally carries a Most Favored Nation (MFN) duty rate of 3.70% ad valorem. However, preferential duty rates may apply under various Free Trade Agreements (FTAs) and trade programs. For instance, goods originating from Canada or Mexico under the USMCA may be eligible for duty-free entry (0.00%). It is crucial to consult the Harmonized Tariff Schedule of the United States (HTSUS) maintained by the US International Trade Commission (USITC) for the most current and specific rates applicable to your country of origin. Documentation verifying the origin of the goods is essential to claim preferential treatment.
How is the duty calculated for HS 731813 if imported into the US at the MFN rate?
The duty for HS code 731813 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared value of the imported goods. For example, if you import 1,000 screw hooks valued at $2.00 each, the total declared value is $2,000.00. Applying the MFN duty rate of 3.70%, the calculated duty would be $2,000.00 \u00d7 0.0370 = $74.00. Importers and customs brokers must ensure accurate valuation and proper classification to avoid penalties.
What are the key classification criteria for HS code 731813?
HS code 731813 specifically covers 'Screw hooks and screw rings'. The primary classification criteria are that the item must be a fastener, made of iron or steel (as per Chapter 73 heading), and designed to be screwed into a surface. 'Screw hooks' are typically characterized by a threaded shank and a hook-shaped end for hanging items. 'Screw rings' have a threaded shank and a loop or ring at the end. Items that are welded, bent without a distinct screw thread, or designed for other fastening methods (e.g., nails, bolts) would not fall under this code. Always refer to the Explanatory Notes of the Harmonized System (WCO) for detailed classification guidance.
Which common trade agreements offer preferential duty rates for HS code 731813 into the US?
Several trade agreements can provide preferential duty rates for HS code 731813 into the United States. These include the United States-Mexico-Canada Agreement (USMCA), which often grants duty-free entry (0.00%) for qualifying goods. Other agreements, such as those with Australia (AU), South Korea (KR), and various Central and South American countries (e.g., CL, CO, PE, PA), may also offer reduced or zero duty rates. To claim these benefits, importers must possess a valid Certificate of Origin or other acceptable proof of origin documentation demonstrating that the goods qualify under the terms of the specific trade agreement.
Are there specific documentation requirements for importing goods under HS code 731813?
Yes, standard documentation is required for importing goods under HS code 731813. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill. Crucially, if claiming preferential duty rates under a trade agreement, a valid Certificate of Origin (COO) or other acceptable proof of origin is mandatory. Importers should also be prepared for potential requests for product specifications or samples to verify classification. Customs brokers play a vital role in ensuring all necessary documentation is accurate and submitted correctly to U.S. Customs and Border Protection (CBP).
