How to Classify This HS Code?

```html

What products does HS 520634 cover?

This subheading covers single cotton yarns, not put up for retail sale, specifically those measuring less than 192.31 decitex but not less than 125 decitex. This corresponds to a metric number exceeding 52 but not exceeding 80 per single yarn, as defined by the World Customs Organization's Harmonized System Nomenclature. Official USITC and EU TARIC databases confirm this precise decitex range for classification under Heading 5206.

What falls outside HS 520634?

The following products are excluded from HS 520634: cotton yarns that are finer or coarser than the specified decitex range (e.g., less than 125 decitex or exceeding 192.31 decitex), cotton yarns put up for retail sale (which fall under other subheadings), and yarns made from other fibers or blends where cotton is not the predominant component. For instance, single yarns of linen or synthetic fibers, even within the same decitex range, would be classified elsewhere.

What are common classification mistakes for HS 520634?

A common error is misinterpreting the decitex measurement or its equivalent metric number. Importers may incorrectly calculate or convert the yarn count, leading to classification in a neighboring subheading. 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. Failure to accurately determine the yarn's decitex is the primary pitfall.

How should importers classify products under HS 520634?

The correct procedure for classifying products under HS 520634 involves first identifying the material as single cotton yarn not put up for retail sale. Subsequently, the importer or customs broker must accurately determine the yarn's decitex. This measurement should be verified against the product's technical specifications or through laboratory testing if necessary, ensuring it falls within the 125 to 192.31 decitex range.

How is the duty calculated for products under HS 520634?

A shipment of 1,000 kilograms of single cotton yarn, measuring 150 decitex and declared at a customs value of $5,000 USD, would attract a US Most Favored Nation (MFN) duty of $175.00. This is calculated using the MFN rate of 3.5% ad valorem applied to the declared customs value ($5,000 USD × 0.035 = $175.00), as published in the USITC Harmonized Tariff Schedule.

Which trade agreements reduce duties for HS 520634?

Several free trade agreements may reduce the applicable duty rate for HS 520634, 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. For goods originating from certain developing countries, the Generalized System of Preferences (GSP) may offer a reduced or Free duty rate. Documentation required typically includes a USMCA Certificate of Origin or a GSP Form A, depending on the specific agreement and origin country.

FAQ

What are the import duty rates for HS code 520634, specifically for cotton yarn measuring between 125 and 192.31 decitex?

For HS code 520634, which covers cotton yarn of carded staple fibres, measuring less than 192.31 decitex but not less than 125 decitex (equivalent to exceeding 52 metric count but not exceeding 80 metric count per single yarn), the Most Favored Nation (MFN) duty rate is typically 4.00%. However, preferential duty rates may apply under various 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 others may be eligible for free entry (0.00% duty). 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 any applicable trade agreements.

How is the decitex measurement for HS code 520634 determined, and what is the significance of the 'metric number' range?

The decitex (dtex) is a unit of linear density for textile fibres and yarns, representing the mass in grams per 10,000 meters of yarn. For HS code 520634, the yarn's linear density must fall within the range of 125 dtex (inclusive) to 192.31 dtex (exclusive). The metric number (Nm) is another measure of yarn count, calculated as the number of 1,000-meter lengths per kilogram. The specified decitex range corresponds to a metric number range exceeding 52 Nm (exclusive) and not exceeding 80 Nm (inclusive) per single yarn. Accurate measurement and declaration of this parameter are critical for correct classification under 520634.

What documentation is typically required when importing cotton yarn classified under HS 520634?

When importing cotton yarn under HS code 520634, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Crucially, to claim preferential duty rates under trade agreements, a Certificate of Origin (COO) is generally mandatory. This document must be issued by the competent authority of the exporting country and attest that the goods meet the rules of origin stipulated in the relevant trade agreement. Importers should also be prepared to provide yarn testing reports or manufacturer declarations to substantiate the decitex or metric count if requested by customs authorities for verification purposes.

Can you provide an example of how import duty for HS 520634 is calculated if the MFN rate applies?

Certainly. If you are importing 1,000 kilograms of cotton yarn classified under HS 520634 and the applicable Most Favored Nation (MFN) duty rate is 4.00%, the duty calculation would be as follows:

First, convert the weight to the value basis, assuming a value of $5,000 USD for the 1,000 kg shipment.

Duty Amount = Value of Goods × Duty Rate Duty Amount = $5,000 USD × 4.00% Duty Amount = $5,000 USD × 0.04 Duty Amount = $200 USD

In this scenario, the import duty would be $200 USD. If the duty were based on a specific rate per weight (e.g., per kg), the calculation would use that specific rate multiplied by the net weight of the imported goods.

Which common trade agreements offer preferential duty rates for HS code 520634, and how can importers verify eligibility?

Several trade agreements provide preferential duty rates, often resulting in free entry (0.00% duty) for goods classified under HS code 520634. Common examples include agreements with 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). To verify eligibility, importers must ensure that the cotton yarn originates from a country that is a party to a preferential trade agreement with the importing country. This requires obtaining a valid Certificate of Origin (COO) from the exporter, which confirms compliance with the agreement's rules of origin. Importers and customs brokers should consult the specific text of the relevant trade agreement and the customs regulations of the importing country for precise requirements and eligible countries.
