How to Classify This HS Code?

```html

What products does HS 520631 cover?

This subheading covers single yarn of cotton, not put up for retail sale, made from uncombed cotton fibres, which is either multiple (folded) or cabled. According to the World Customs Organization's Harmonized System Explanatory Notes, "multiple (folded) yarn" consists of two or more single yarns twisted together, while "cabled yarn" is formed by twisting together two or more folded yarns. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, emphasizing that the yarn must be composed of uncombed cotton fibres and be in a form other than single yarn or put up for retail sale.

What falls outside HS 520631?

The following products are excluded from HS 520631: single yarns of cotton (classified under HS 520610 or 520620), yarns of combed cotton fibres (classified under HS 5205), yarns of other textile fibres, and yarns put up for retail sale (which are typically classified under HS 5210). For instance, a multiple yarn of cotton that has undergone a combing process would be classified under HS 5205, not 5206. Similarly, cotton yarn sold in small skeins for home knitting falls under different headings.

What are common classification mistakes for HS 520631?

A common error is misinterpreting the "uncombed fibres" requirement. If the cotton fibres have been combed, the yarn would be classified under heading 5205. Another mistake involves confusing "multiple (folded) or cabled yarn" with single yarn, which is covered by other subheadings within 5206. Importers must carefully examine the manufacturing process and the final form of the yarn, adhering to General Interpretative Rule 1 of the Harmonized System, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes.

How should importers classify products under HS 520631?

The correct procedure for classifying products under HS 520631 involves a systematic approach. First, confirm that the yarn is made from cotton fibres. Second, verify that the fibres were uncombed. Third, determine if the yarn is multiple (folded) or cabled, meaning it consists of two or more single yarns twisted together. Finally, ensure the yarn is not put up for retail sale. Consulting official tariff schedules like the USITC HTS or the EU TARIC, and if necessary, seeking a binding ruling from customs authorities, is crucial for accurate classification.

How is the duty calculated for products under HS 520631?

A 100% cotton multiple yarn, weighing 500 kilograms and declared at a customs value of $2,500 USD, would attract a US duty of $125.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($2,500 USD × 0.05 = $125.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule (HTS) for subheading 520631. Note that specific duties may also apply depending on the yarn's count.

Which trade agreements reduce duties for HS 520631?

Several free trade agreements may reduce the applicable duty rate for HS 520631, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, yarn originating from Canada or Mexico may be eligible for a preferential rate of Free. To claim this preference, a self-certified origin statement on the commercial invoice or a separate certificate of origin is typically required. Additionally, the Generalized System of Preferences (GSP) may offer reduced or free entry for eligible goods from certain developing countries, requiring a GSP Form A.
