How to Classify This HS Code?
What products does HS 520644 cover?
This subheading covers single cotton yarns, not put up for retail sale, specifically those measuring between 125 and 192.31 decitex (equivalent to exceeding 52 metric count but not exceeding 80 metric count per single yarn). According to the World Customs Organization's Harmonized System Nomenclature, this category is defined by precise linear density. For example, the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this range for cotton sewing thread and other single yarns.
What falls outside HS 520644?
The following products are excluded from HS 520644: cotton yarns with a decitex outside the 125-192.31 range, such as finer yarns (e.g., less than 125 decitex) which fall under 520643, or coarser yarns (e.g., exceeding 192.31 decitex) which fall under 520645. Additionally, blended yarns containing synthetic or man-made fibers, or yarns put up for retail sale, are classified under different headings, such as Chapter 55 for man-made fibers or Heading 5207 for retail-packaged cotton yarn.
What are common classification mistakes for HS 520644?
A common error is miscalculating or misinterpreting the decitex or metric count of the single yarn. Importers may rely on incorrect product specifications or fail to perform the necessary calculations to determine the precise linear density. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. Incorrectly assuming the yarn falls within the specified range without verification can lead to misclassification.
How should importers classify products under HS 520644?
The correct procedure for classifying single cotton yarns under HS 520644 involves accurately determining the yarn's linear density in decitex. Importers must obtain precise specifications from the manufacturer, confirming the yarn is 100% cotton and not put up for retail sale. If the decitex falls between 125 and 192.31, the product should be classified here. Customs brokers should verify these specifications against the product's physical characteristics and the definitions provided in the relevant tariff schedule, such as the USITC HTS or UK Trade Tariff.
How is the duty calculated for products under HS 520644?
A shipment of 1,000 kilograms of single cotton yarn, measuring 150 decitex, declared at a customs value of $5,000 USD, would attract a US duty of $150.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.0% ad valorem (0.03 × $5,000 USD = $150.00). This rate is published in the USITC Harmonized Tariff Schedule for subheading 5206.44.0000.
Which trade agreements reduce duties for HS 520644?
Several free trade agreements may reduce the applicable duty rate for HS 520644, 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 preferential rates for goods from certain developing countries, potentially reaching Free. To claim these preferences, a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries is typically required, depending on the specific origin country and the importing jurisdiction's regulations.

FAQ
What are the import duty rates for HS code 520644, specifically for cotton yarn measuring between 125 and 192.31 decitex?
The Most Favored Nation (MFN) duty rate for HS code 520644 is 4.00% ad valorem. However, preferential rates are available for imports from countries with trade agreements. For example, imports from Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), Singapore (SG), and the United States (US) may be eligible for duty-free entry (Free). It is crucial to verify the specific trade agreement and the country of origin to determine the applicable duty rate. Source: USITC Harmonized Tariff Schedule.
How is the decitex measurement for HS code 520644 determined, and what is the significance of the 'metric number' range?
Decitex (dtex) is a unit of linear density for textile fibers and yarns, representing the weight in grams of 10,000 meters of the yarn. For HS code 520644, the yarn must have a linear density measuring per single yarn that is not less than 125 dtex but not exceeding 192.31 dtex. The 'metric number' is another way to express yarn count, where a higher metric number indicates a finer yarn. The range specified (exceeding 52 metric number but not exceeding 80 metric number per single yarn) is equivalent to the decitex range of 125 to 192.31 dtex. This precise measurement is critical for correct classification. Source: WCO Explanatory Notes to the Harmonized System.
What documentation is typically required when importing cotton yarn classified under HS code 520644?
When importing cotton yarn under HS code 520644, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. To claim preferential duty rates under a trade agreement, a Certificate of Origin (COO) issued by the exporting country's competent authority is essential. The COO must clearly state that the goods originate from the beneficiary country and meet the rules of origin stipulated in the respective trade agreement. Importers should also be prepared to provide yarn test reports or manufacturer's declarations confirming the decitex measurement if requested by customs authorities.

Can you provide a concrete example of how the import duty for HS code 520644 is calculated if the MFN rate applies?
Certainly. If you are importing 1,000 kilograms of cotton yarn classified under HS code 520444, and the applicable duty rate is the MFN rate of 4.00% ad valorem, the duty calculation would be as follows: First, determine the value of the imported goods. Let's assume the customs value is $5,000 USD. The duty amount is calculated as: Duty = Customs Value × Duty Rate. Duty = $5,000 USD × 4.00% = $200 USD. Therefore, the import duty would be $200 USD. This calculation assumes the value is based on the CIF (Cost, Insurance, and Freight) value, which is common practice.
Which major trade agreements offer preferential duty rates for HS code 520644, and how can importers verify eligibility?
Several trade agreements provide preferential duty rates for HS code 520644. Notably, the United States has agreements like the US-Australia Free Trade Agreement (AUSFTA), US-Chile Free Trade Agreement (USCLFTA), US-Colombia Trade Promotion Agreement (CTPA), US-Israel Free Trade Area Agreement (USIFTAA), US-Jordan Free Trade Agreement (USJFTA), US-Korea Free Trade Agreement (USKFTA), US-Morocco Free Trade Agreement (USMFTA), US-Oman Free Trade Agreement (USOFTA), US-Panama Trade Promotion Agreement (USPTPA), US-Peru Trade Promotion Agreement (USPPTA), and US-Singapore Free Trade Agreement (USSFTA). To verify eligibility, importers must ensure the yarn is considered 'originating' from the partner country according to the specific rules of origin within that agreement. This typically involves obtaining a valid Certificate of Origin and potentially providing evidence of direct shipment and compliance with value content or processing requirements. Consult the text of the relevant trade agreement and the customs regulations of the importing country for precise details. Source: USITC Harmonized Tariff Schedule, Annexes on Rules of Origin.
