How to Classify This HS Code?

What products does HS 551030 cover?

This subheading covers yarns of synthetic staple fibres, mixed mainly or solely with cotton, which are not put up for retail sale. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes yarns where synthetic staple fibres constitute the predominant component by weight, blended with cotton. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that the key determinant is the predominance of synthetic staple fibres, with cotton being the secondary or sole other fibre component.

What falls outside HS 551030?

The following products are excluded from HS 551030: yarns composed primarily of cotton with synthetic fibres as the secondary component, which would fall under Chapter 52; 100% synthetic staple fibre yarns, classified under HS 5509; and yarns of artificial staple fibres mixed with cotton, which are classified elsewhere in Chapter 55. Additionally, yarns put up for retail sale, regardless of their fibre composition, are excluded and typically classified under HS 5510.90.

What are common classification mistakes for HS 551030?

A common error is misinterpreting the "mainly or solely with cotton" clause, leading to the misclassification of yarns where cotton is the predominant fibre. General Interpretative Rule 3(b) of the Harmonized System, concerning mixtures, is often overlooked; the classification should be based on the essential character of the goods, which in this case is determined by the predominant fibre. Importers may also incorrectly classify blended yarns with a significant percentage of other fibres, such as wool or silk, under this subheading.

How should importers classify products under HS 551030?

The correct procedure for classifying yarns under HS 551030 involves a two-step process: first, determine the fibre composition by weight. If synthetic staple fibres are the predominant component (more than 50% by weight) and cotton is the only other significant fibre, then the yarn likely falls within this subheading. Secondly, confirm that the yarn is not put up for retail sale. Importers and customs brokers should consult the specific national tariff schedule, such as the USITC HTS or the UK Trade Tariff, for detailed notes and definitions.

How is the duty calculated for products under HS 551030?

A 100% polyester staple fibre yarn, mixed with 30% cotton, weighing 10 kilograms and declared at a customs value of $500 USD, would attract a US duty of $150.00. This is calculated using the Most Favored Nation (MFN) duty rate of 15% ad valorem, applied to the declared customs value: 15% × $500 USD = $75.00. This calculation is based on the USITC Harmonized Tariff Schedule, which often uses ad valorem rates for such textile yarns.

Which trade agreements reduce duties for HS 551030?

Several free trade agreements may reduce the applicable duty rate for HS 551030, including the United States-Mexico-Canada Agreement (USMCA), which can provide for duty-free entry for qualifying yarns originating from Canada or Mexico. The EU's Generalized Scheme of Preferences (GSP) may offer reduced rates for yarns from certain developing countries. Documentation required to claim preference under USMCA typically involves a self-certified origin statement, while EU preferences might necessitate an EUR.1 movement certificate.

FAQ

What are the import duty rates for HS code 551030 (Other yarn, mixed mainly or solely with cotton)?

The Most Favored Nation (MFN) duty rate for HS code 551030 is 7.5% ad valorem. However, preferential duty rates are available for goods originating from countries with trade agreements with the importing country. For example, under certain agreements, duty rates can be as low as Free (0.00%) for 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). It is crucial to consult the specific tariff schedule of the importing country and verify the preferential status of the goods based on the Certificate of Origin.

How is the import duty for HS code 551030 calculated, and can you provide an example?

The duty for HS code 551030 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if the MFN duty rate is 7.5% and the declared customs value of a shipment of yarn is $10,000 USD, the import duty would be $10,000 USD * 7.5% = $750 USD. If the yarn is subject to a specific duty (per unit), the calculation would be rate per unit × quantity. Always confirm the applicable duty basis (ad valorem, specific, or compound) in the importing country's tariff schedule.

What are the key classification criteria for HS code 551030?

HS code 551030 covers 'Other yarn, mixed mainly or solely with cotton'. The primary classification criteria are: 1. The material composition: The yarn must be predominantly cotton, meaning cotton constitutes the highest percentage by weight of the fiber mixture. 2. The type of yarn: This code applies to yarns other than those specifically classified elsewhere in Chapter 55, such as single, multiple (folded) or cabled yarn. If the yarn is not specifically covered by other headings in Chapter 55 (e.g., 5508, 5509), and is predominantly cotton, it falls under 551030. Verification with the World Customs Organization (WCO) Harmonized System Explanatory Notes or national customs rulings is recommended for complex mixtures.

What documentation is typically required for importing goods under HS code 551030?

Standard import documentation for HS code 551030 typically includes a commercial invoice, packing list, and bill of lading or air waybill. Crucially, for claiming preferential duty rates under trade agreements, a valid Certificate of Origin is mandatory. This document must certify that the yarn originates from a country that is a party to the applicable trade agreement. Importers should also be prepared to provide technical specifications or fiber analysis reports if customs authorities require verification of the material composition to confirm correct classification.

Which common trade agreements offer preferential duty rates for HS code 551030, and how can importers leverage them?

Several trade agreements offer preferential duty rates for HS code 551030. Examples include agreements between the US and countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), and Singapore (SG), where the duty can be Free (0.00%). To leverage these agreements, importers must ensure the yarn qualifies as 'originating' from the partner country according to the rules of origin stipulated in the specific trade agreement. This requires obtaining a compliant Certificate of Origin from the exporter and maintaining proper records to substantiate the claim. Consulting the tariff database of the importing country (e.g., USITC for the US, EU TARIC for the EU, UK Trade Tariff for the UK) will provide specific details on applicable agreements and their requirements.
