HS 520531 Multiple (folded) or cabled yarn, of uncombed fibres
Quick Answer: Cotton yarn of multiple (folded) or cabled construction, made from uncombed cotton fibres, enters the UK duty-free, the EU at 4.00% ad valorem, and the US with rates varying from Free to 11.9% ad valorem depending on the country of origin. This classification specifically applies to yarns where individual strands of uncombed cotton have been twisted together to form a thicker, more robust thread, or multiple such threads are further twisted together. Importers should verify specific US duty rates based on preferential trade agreements. CustomTariffs aggregates this data, highlighting the importance of origin for US imports.

How to Classify This HS Code?
What products does HS 520531 cover?
This subheading covers multiple (folded) or cabled yarn, spun from cotton fibres, which are not carded. According to the World Customs Organization's Harmonized System Nomenclature, this category specifically includes yarns where two or more single yarns have been twisted together to form a single strand, or where the fibres themselves have been processed in a way that results in a folded or cabled structure before spinning. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that the defining characteristic is the multiple or cabled structure of yarn derived from uncombed cotton fibres.
What falls outside HS 520531?
The following products are excluded from HS 520531: single yarns of uncombed cotton fibres (classified under HS 520511 or 520512), yarns of combed cotton fibres (classified under HS 520521 through 520529), and yarns of cotton mixed with other materials. Also excluded are sewing thread of cotton (HS 5206) and yarns of other textile materials, such as linen or synthetic fibres. For instance, a single strand of cotton yarn, even if it has a high twist, would not fall under this subheading if it is not a multiple or cabled construction.
What are common classification mistakes for HS 520531?
A common error is misinterpreting the "multiple (folded) or cabled" requirement. Importers may mistakenly classify single yarns that have been highly twisted as multiple or cabled yarns. According to General Interpretative Rule 1 of the Harmonized System, classification is determined by the terms of the headings and any relative section or chapter notes. If a yarn is composed of only one strand, regardless of its twist, it is a single yarn and should not be classified under this subheading. Another mistake is confusing cotton yarns with those made from other staple fibres.
How should importers classify products under HS 520531?
The correct procedure for classifying products under HS 520531 involves a detailed examination of the yarn's construction. Importers and customs brokers must verify that the yarn is indeed composed of two or more single yarns twisted together or has a cabled structure. They should consult the product's technical specifications and, if necessary, obtain laboratory analysis. Cross-referencing with official tariff databases like the USITC HTS or the EU TARIC is crucial to confirm the correct classification based on the fibre content and yarn structure, ensuring compliance with Chapter 52 notes.
How is the duty calculated for products under HS 520531?
A shipment of 1,000 kilograms of 3-ply cotton yarn, not carded, with a declared customs value of $5,000 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 520531, the duty would be $175.00 USD (3.5% × $5,000 USD). This calculation is based on the declared value of the goods, demonstrating the ad valorem nature of the duty for this specific classification in the United States.
Which trade agreements reduce duties for HS 520531?
Several free trade agreements may reduce the applicable duty rate for HS 520531, 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. The Generalized System of Preferences (GSP) may also offer reduced or Free rates for eligible goods from developing countries. To claim preference under USMCA, a valid Certificate of Origin or a self-certified origin statement is typically required. For GSP, a Form A (GSP) is generally needed, depending on the beneficiary country and the importing jurisdiction's specific requirements.

FAQ
What are the typical import duty rates for HS code 520531, 'Multiple (folded) or cabled yarn, of uncombed fibres'?
The Most Favored Nation (MFN) duty rate for HS code 520531 can vary. For example, under the US Harmonized Tariff Schedule (USHTS), the general rate can be 5.8% ad valorem. However, preferential rates are often available. For instance, under various Free Trade Agreements (FTAs) and trade programs, such as those with Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), Singapore (SG), and others, the duty rate may be Free (0.00%). It is crucial to consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment based on the origin of the goods and applicable trade agreements.
What specific criteria define 'multiple (folded) or cabled yarn' under HS code 520531?
HS code 520531 covers yarn spun from cotton fibres that are not combed. The key distinguishing factor for this code is that the yarn is either 'multiple' (two or more single yarns twisted together), 'folded' (similar to multiple, implying a twisting process), or 'cabled' (multiple folded yarns twisted together). This contrasts with single yarns. The fibres must remain 'uncombed,' meaning they have not undergone the combing process which aligns and removes shorter fibres to produce a finer, smoother yarn. The WCO's Explanatory Notes to Chapter 52 provide detailed guidance on yarn construction and the distinction between combed and uncombed fibres.
What documentation is typically required for importing goods classified under HS 520531?
When importing goods under HS code 520531, standard customs documentation is required. This includes a commercial invoice detailing the value, quantity, and description of the yarn; a packing list specifying the contents of each package; and a bill of lading or air waybill for transport. If claiming preferential duty rates under a trade agreement, a Certificate of Origin is usually mandatory, demonstrating that the goods meet the rules of origin for that specific agreement. Importers should also be prepared to provide technical specifications or samples if requested by customs authorities to verify the classification and fibre content.
How is the import duty calculated for HS 520531, and can you provide a numerical example?
The import duty for HS code 520531 is typically calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. For example, if the MFN duty rate is 5.8% ad valorem and you are importing 1,000 kilograms of yarn with a declared customs value of $3,000 USD, the duty calculation would be: Duty Amount = Customs Value × Duty Rate. In this case, Duty Amount = $3,000 USD × 5.8% = $174 USD. If a specific duty rate (e.g., per kilogram) were applicable, the calculation would be based on the quantity. Always confirm the applicable duty basis (ad valorem, specific, or compound) with the importing country's customs authority.
Which major trade agreements commonly offer duty-free entry for HS code 520531?
Several major trade agreements facilitate duty-free or reduced-duty entry for goods classified under HS code 520531, provided the goods meet the relevant rules of origin. Examples include agreements between the United States and countries like South Korea (US-Korea Free Trade Agreement), Colombia (US-Colombia Trade Promotion Agreement), and Chile (US-Chile Free Trade Agreement). The European Union's Generalized Scheme of Preferences (GSP) and its various Economic Partnership Agreements (EPAs) or Association Agreements with numerous countries can also grant preferential access. The UK also has a network of trade agreements that may offer reduced or zero duties. Importers must verify the specific terms and origin requirements of each agreement applicable to their trade lane.
