How to Classify This HS Code?
What products does HS 520643 cover?
This subheading covers single cotton yarns, not put up for retail sale, specifically those measuring less than 232.56 decitex but not less than 192.31 decitex. This corresponds to a metric count exceeding 43 but not exceeding 52 per single yarn. According to the WCO Harmonized System Explanatory Notes and the USITC Harmonized Tariff Schedule (HTS), this classification is for fine-count single yarns of cotton, suitable for weaving or knitting fine fabrics, where the decitex measurement is the primary determinant of classification within this specific range.
What falls outside HS 520643?
The following products are excluded from HS 520643: single cotton yarns with a decitex measurement outside the specified range of 192.31 to 232.56, or those that are put up for retail sale. Also excluded are multiple or cabled yarns of cotton, as well as yarns of other textile materials like linen, wool, or synthetic fibers, even if their decitex falls within the numerical range. For instance, a single cotton yarn of 250 decitex would be classified under a different subheading within heading 5206.
What are common classification mistakes for HS 520643?
A common error is miscalculating or misinterpreting the decitex value or its equivalent metric count. Importers may confuse single yarn with multiple or cabled yarns, which fall under different HS codes. Furthermore, failing to verify if the yarn is intended for retail sale can lead to misclassification, as such yarns are typically classified elsewhere. 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 520643?
The correct procedure for classifying products under HS 520643 involves first confirming that the yarn is made of cotton and is a single yarn, not put up for retail sale. Next, the decitex of the single yarn must be accurately measured or obtained from the manufacturer's specifications, ensuring it falls precisely between 192.31 and 232.56 decitex. This range corresponds to a metric count of 43 to 52. Verification against official tariff schedules like the USITC HTS or EU TARIC is essential for final confirmation.
How is the duty calculated for products under HS 520643?
A shipment of 1,000 kilograms of single cotton yarn, measuring 200 decitex (equivalent to approximately 49 metric count), declared at a customs value of $5,000 USD, would attract a US duty of $175.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.5% ad valorem, applied to the declared customs value ($5,000 USD × 0.035 = $175.00). This rate is published in the USITC Harmonized Tariff Schedule, specifically under HTS subheading 5206.43.0000.
Which trade agreements reduce duties for HS 520643?
Several free trade agreements may reduce the applicable duty rate for HS 520643, including the United States-Mexico-Canada Agreement (USMCA), where originating goods from Canada and Mexico can enter the US duty-free. For goods originating from countries benefiting from the US Generalized System of Preferences (GSP), such as Bangladesh, the duty rate can be reduced to Free. Documentation required typically includes a USMCA Certificate of Origin for USMCA trade or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ
What are the import duty rates for HS code 520643, specifically for single yarn of cotton, measuring between 192.31 and 232.56 decitex?
The Most Favored Nation (MFN) duty rate for HS code 520643 is 9.2% ad valorem. However, preferential duty rates are available for imports from certain countries. For example, under various Free Trade Agreements (FTAs), countries such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), and Singapore (SG) may benefit from a Free (0.00%) duty rate. It is crucial to verify the specific origin of the goods and the applicable preferential agreement to determine the correct duty. Always consult the latest official tariff schedules, such as the USITC Harmonized Tariff Schedule or the EU's TARIC database, for definitive rates.
How is the classification of single cotton yarn under HS 520643 determined, given the decitex range?
The classification under HS 520643 hinges on the linear density of the single yarn, measured in decitex (dtex). This specific code applies to single yarns of cotton where the linear density is not less than 192.31 dtex but not exceeding 232.56 dtex. This range corresponds to a metric number exceeding 43 but not exceeding 52 per single yarn. Importers must ensure their commercial documentation, such as the invoice and packing list, accurately states the yarn's linear density. Laboratory testing may be required if there is doubt about the stated decitex value. The WCO's Explanatory Notes to Chapter 52 provide further guidance on yarn measurement and classification.
What documentation is essential when importing cotton yarn classified under HS 520643 to ensure compliance?
To ensure smooth customs clearance for imports under HS 520643, importers and customs brokers should prepare the following key documents: a commercial invoice detailing the yarn's fiber content, linear density (decitex), quantity, and value; a packing list specifying the contents of each package; a bill of lading or air waybill for transport; and a certificate of origin if preferential duty rates are being claimed. For cotton products, a declaration of origin or specific certifications may be required by some importing countries to verify the source of the cotton, especially if specific trade agreements or regulations apply. Always check the specific import requirements of the destination country.
Can you provide an example of how import duty for HS 520643 is calculated for a shipment valued at $10,000 USD, assuming the MFN rate?
Certainly. If a shipment of cotton yarn classified under HS 520643 has a customs value of $10,000 USD and is subject to the standard Most Favored Nation (MFN) duty rate of 9.2% ad valorem, the duty calculation would be as follows: Duty Amount = Customs Value × Duty Rate. In this case, Duty Amount = $10,000 USD × 9.2% (or 0.092). Therefore, the import duty would be $920 USD. This calculation assumes no other duties, taxes, or fees apply. If a preferential rate, such as Free (0.00%) from a partner country, were applicable, the duty would be $0 USD.
Which common trade agreements might offer reduced or zero duty rates for HS code 520643, and how can importers verify eligibility?
Several trade agreements can provide preferential duty treatment for HS code 520643. For instance, the United States has FTAs with countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), and Singapore (SG) that often grant duty-free access for qualifying goods. The European Union also has numerous trade agreements. To verify eligibility, importers must: 1. Confirm the yarn originates from a country that is a party to an applicable trade agreement. 2. Ensure the yarn meets the rules of origin stipulated in that specific agreement (e.g., substantial transformation, regional value content). 3. Obtain a valid Certificate of Origin or proof of origin as required by the agreement. Importers should consult the official text of the relevant trade agreement and the customs authority of the importing country for precise requirements.
