How to Classify This HS Code?
What products does HS 901790 cover?
This subheading covers parts and accessories specifically designed for instruments and appliances of heading 9017, which includes drawing, marking-out, mathematical-calculating, and measuring instruments. According to the WCO Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this includes components such as rulers, protractors, compasses, dividers, and styluses when they are solely intended for use with instruments of heading 9017, and not as standalone general-purpose tools. For instance, a replacement lead for a technical drawing pen or a specialized measuring head for a coordinate measuring machine would fall here.
What falls outside HS 901790?
The following products are excluded from HS 901790: general-purpose tools that may be used in drafting or measuring but are not specifically designed as parts of instruments under heading 9017, such as standard pencils, erasers, or basic rulers not intended for technical drawing instruments. Additionally, complete measuring instruments, even if small or simple, are classified under their respective headings within Chapter 90, not as parts. For example, a standalone digital caliper, while a measuring device, is classified under 9017.20 or similar, not as a part of 9017.90.
What are common classification mistakes for HS 901790?
A common error is misclassifying general-purpose stationery items or tools as parts of instruments under HS 901790. This often occurs when the item, while potentially useful in drafting or technical work, is not exclusively designed or intended for integration into a specific instrument of heading 9017. For example, a standard mechanical pencil used for general writing might be incorrectly classified here if it lacks the specific features or intended use for technical drawing instruments. 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.
How should importers classify products under HS 901790?
The correct procedure for classifying products under HS 901790 involves a thorough examination of the item's intended use and design. Importers and customs brokers must determine if the part or accessory is specifically manufactured for use with instruments falling under heading 9017. Consulting the WCO Explanatory Notes and the specific tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, is essential. If the item is a component of a drawing, mathematical-calculating, or measuring instrument of heading 9017, and not a standalone product, then HS 901790 is likely applicable.
How is the duty calculated for products under HS 901790?
A set of 10 replacement styluses for a digital plotter, with a declared customs value of $150 USD, would attract a US duty of $15.00. This is calculated using the Most Favored Nation (MFN) duty rate of 10% ad valorem, as published in the USITC Harmonized Tariff Schedule. The calculation is: $150 USD (declared value) × 10% (MFN duty rate) = $15.00 (duty amount). This example assumes no preferential trade agreements apply and the goods are not subject to any other duties or taxes.
Which trade agreements reduce duties for HS 901790?
Several free trade agreements may reduce the applicable duty rate for HS 901790, 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 reduced or Free duties for eligible goods from 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 requirements of the importing jurisdiction.

FAQ
What are the typical import duty rates for HS code 901790 (Parts and accessories for drawing, marking-out, calculating and other instruments)?
The import duty rates for HS code 901790 can vary significantly depending on the importing country and any applicable trade agreements. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is often 2.00% ad valorem. However, preferential rates under various Free Trade Agreements (FTAs) can be lower, including Free (0.00%) for countries like Australia (AU), Canada (CA), Mexico (MX), and others under the USMCA, or specific rates like 2.70% ad valorem for certain origins. It is crucial to consult the specific tariff schedule of the importing country, such as the USITC HTS or the EU TARIC database, for the definitive rate applicable to your specific import.
How is the duty calculated for parts and accessories classified under HS 901790?
The duty for parts and accessories under HS 901790 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if parts for a calculating instrument are valued at $10,000 USD and the applicable duty rate is 2.00% ad valorem, the import duty would be $10,000 USD * 0.02 = $200 USD. In some cases, the duty rate applicable to the complete article of which the part or accessory forms an integral part may apply, but this is less common for this specific subheading. Always verify the basis of duty calculation with the official tariff schedule.
What documentation is typically required when importing parts and accessories under HS code 901790?
When importing parts and accessories classified under HS 901790, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list specifying the contents of each package; and a bill of lading or air waybill as the transport document. Depending on the importing country and the specific nature of the parts, additional documentation such as a certificate of origin may be necessary to claim preferential duty rates under trade agreements. Importers and customs brokers should consult the customs authority of the destination country for a comprehensive list of required documents.
Are there preferential duty rates available for HS 901790 under major trade agreements?
Yes, preferential duty rates are often available for parts and accessories under HS 901790 through various trade agreements. For example, under the USMCA (United States-Mexico-Canada Agreement), many goods, including parts and accessories, may qualify for duty-free treatment (0.00%) if they meet the rules of origin. Similarly, agreements with countries like South Korea (KR), Chile (CL), and others often provide reduced or zero duty rates. Importers must ensure they have the necessary proof of origin, such as a certificate of origin, to claim these preferential rates. The specific list of countries offering preferential rates and the applicable conditions can be found in the tariff schedule of the importing country, often indicated by special codes (e.g., 'A' for Australia, 'AU' for Australia in the US HTS).
What are the criteria for classifying an item as a 'part or accessory' under HS 901790?
To be classified under HS 901790 as a part or accessory for drawing, marking-out, calculating, and other instruments, the item must be specifically designed or adapted for use with such instruments and not be readily capable of use for any other purpose. It should contribute to the function of the main instrument. For instance, a specialized stylus for a digital drafting table or a replacement gear for a mechanical calculator would likely fall under this code. However, general-purpose items like screws, nuts, or basic electrical components that are not specifically designed for these instruments would typically be classified elsewhere based on their own material or function. Consulting the Explanatory Notes to the Harmonized System (WCO) and national customs rulings can provide further guidance on classification.
