How to Classify This HS Code?

What products does HS 520624 cover?

This subheading covers single, unbleached or bleached cotton sewing thread, measuring less than 192.31 decitex but not less than 125 decitex, which corresponds to a metric number exceeding 52 but not exceeding 80. As per the World Customs Organization (WCO) Harmonized System Explanatory Notes and the US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS), this classification is based on the specific linear density of the yarn, ensuring precise identification of fine cotton sewing threads used in various textile applications.

What falls outside HS 520624?

The following products are excluded from HS 520624: cotton sewing thread with a linear density outside the specified range (e.g., finer than 125 decitex or coarser than 192.31 decitex), sewing thread made from materials other than cotton, or sewing thread that has been dyed or otherwise treated beyond simple bleaching. For instance, sewing thread measuring 100 decitex would fall under a different subheading within 5206, and dyed cotton sewing thread would typically be classified under heading 5207.

What are common classification mistakes for HS 520624?

A common error is miscalculating or misinterpreting the linear density (decitex) of the sewing thread. Importers may confuse metric number with decitex or fail to account for the "unbleached or bleached" condition. 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 a thread falls within the specified decitex range without precise measurement can lead to misclassification.

How should importers classify products under HS 520624?

The correct procedure for classifying sewing thread under HS 520624 involves first confirming the material is 100% cotton and then accurately determining its linear density in decitex. This requires consulting the product's technical specifications or performing laboratory testing. If the thread is unbleached or bleached and its decitex falls between 125 and 192.31, it meets the criteria for this subheading.

How is the duty calculated for products under HS 520624?

A spool of unbleached cotton sewing thread weighing 100 grams (approximately 100,000 decitex, which is roughly 100 metric number, thus outside this range, let's adjust for accuracy) – let's consider a spool of unbleached cotton sewing thread weighing 50 grams, with a linear density of 150 decitex (approximately 67 metric number). If declared at a customs value of $100 USD, and assuming a Most Favored Nation (MFN) duty rate of 2.5% ad valorem as per the USITC HTS, the US duty would be $2.50 (2.5% × $100). This is calculated using the MFN rate published in the USITC Harmonized Tariff Schedule.

Which trade agreements reduce duties for HS 520624?

Several free trade agreements may reduce the applicable duty rate for HS 520624. For instance, under the United States-Mexico-Canada Agreement (USMCA), originating cotton sewing thread from Canada or Mexico can enter the US duty-free. Similarly, the Generalized System of Preferences (GSP) may offer reduced or free entry for qualifying goods from designated developing countries. Documentation required typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries.

FAQ

What are the import duty rates for HS code 5206.24?

For HS code 5206.24, which covers cotton sewing thread, not put up for retail sale, measuring less than 192.31 decitex but not less than 125 decitex (exceeding 52 metric number but not exceeding 80 metric number), the Most Favored Nation (MFN) duty rate is typically 4.00% ad valorem. 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 duty-free entry (Free). It is crucial to verify the specific preferential rate applicable to the country of origin and the terms of the relevant trade agreement. Consult the USITC Harmonized Tariff Schedule or the EU TARIC database for the most current and precise rates.

How is the duty for HS 5206.24 calculated, and can you provide an example?

The duty for HS code 5206.24 is generally calculated on an ad valorem basis, meaning it's a percentage of the declared value of the imported goods. For instance, if the MFN duty rate is 4.00% and you import 1,000 kilograms of sewing thread valued at $5,000 USD, the duty calculation would be: Duty = Value × Duty Rate = $5,000 USD × 4.00% = $200 USD. If a specific duty or a combination of specific and ad valorem duties applies, the calculation would be adjusted accordingly. Always refer to the official tariff schedule for the exact duty basis and rate.

What are the key classification criteria for HS code 5206.24?

The primary classification criteria for HS code 5206.24 are: 1. Material: The thread must be made of cotton. 2. Type: It must be sewing thread. 3. Presentation: It must not be put up for retail sale. 4. Linear Density: It must measure less than 192.31 decitex but not less than 125 decitex. This is equivalent to exceeding 52 metric number (Nm) but not exceeding 80 metric number (Nm). The metric number (Nm) is defined as the number of 1-gram skeins of yarn that are 1 meter in length. A higher Nm indicates a finer yarn. Importers must ensure their product meets all these criteria to be correctly classified under this code.

What documentation is typically required for importing goods under HS code 5206.24?

When importing goods classified under HS code 5206.24, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill for transport. Crucially, to claim preferential duty rates under trade agreements, a Certificate of Origin (COO) issued by the exporting country's competent authority or a declaration of origin from the exporter, compliant with the specific agreement's rules, will be necessary. For cotton products, documentation verifying the origin of the cotton itself might also be requested to ensure compliance with rules of origin. Customs brokers should verify the exact requirements with the importing country's customs authority.

Which common trade agreements offer preferential duty rates for HS code 5206.24?

Several trade agreements can provide preferential duty rates, often including duty-free entry, for goods classified under HS code 5206.24, depending on the country of origin. Examples of agreements that may offer such benefits include the US Free Trade Agreements with countries like South Korea (KORUS FTA), Australia (AUSFTA), Chile (CLTCL), and Colombia (CTPA). The European Union's network of Association Agreements and Free Trade Agreements also provides preferential access for many countries. The UK also has its own set of trade agreements post-Brexit. Importers should consult the specific tariff schedule of the importing country (e.g., USITC, EU TARIC, UK Trade Tariff) and the text of the relevant trade agreement to confirm eligibility and any specific conditions or rules of origin that must be met to benefit from reduced or eliminated duties.
