How to Classify This HS Code?
What products does HS 550952 cover?
This subheading covers synthetic staple fibres, not carded, combed or otherwise processed for spinning, that are mixed mainly or solely with wool or fine animal hair. According to the World Customs Organization's Harmonized System Explanatory Notes, this classification is determined by the predominant fibre content, where synthetic fibres constitute the majority of the mixture, and the presence of wool or fine animal hair is a significant component. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that the key criterion is the blend composition, specifically the dominance of synthetic fibres alongside wool or fine animal hair.
What falls outside HS 550952?
The following products are excluded from HS 550952: yarns where wool or fine animal hair is the predominant fibre, or where the synthetic fibre content is not the main component. Also excluded are yarns composed solely of synthetic fibres, or those mixed with other vegetable or man-made fibres in proportions that do not meet the criteria of being "mainly or solely with wool or fine animal hair." For instance, a yarn predominantly of polyester mixed with a small percentage of wool would not fall under this code, nor would a yarn of pure wool or pure synthetic staple fibre.
What are common classification mistakes for HS 550952?
A common error is misinterpreting the "mainly or solely" criterion, leading to incorrect classification when the fibre composition is not clearly defined or when the percentage of wool or fine animal hair is not accurately determined. This can occur when the synthetic fibre content is only slightly above 50% or when other fibres are present in significant quantities. Adherence to General Rule of Interpretation (GRI) 3(b) for mixtures and composite goods is crucial, ensuring the classification is based on the essential character of the goods, which in this case is the blend of synthetic fibres with wool or fine animal hair.
How should importers classify products under HS 550952?
The correct procedure for classifying products under HS 550952 involves a thorough analysis of the fibre composition of the yarn. Importers and customs brokers must obtain precise percentage breakdowns of all fibres present in the yarn. The primary determinant is whether synthetic staple fibres are the predominant component, mixed with wool or fine animal hair. Verification against the official nomenclature and relevant national tariff schedules, such as the USITC HTS or EU TARIC, is essential to confirm the correct subheading and any associated duty rates or import requirements.
How is the duty calculated for products under HS 550952?
A batch of 100 kilograms of a polyester-wool blend yarn (HS 550952) declared at a customs value of $500 USD would attract a US duty of $35.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.5% ad valorem, applied to the declared value: 3.5% of $500 USD = $17.50. If the yarn were classified under a specific quantity-based duty, for example, $0.35 per kilogram, the duty would be $0.35/kg * 100 kg = $35.00. This example uses a hypothetical quantity-based rate for illustrative purposes, as actual rates vary by jurisdiction and are published in the USITC Harmonized Tariff Schedule.
Which trade agreements reduce duties for HS 550952?
Several free trade agreements may reduce the applicable duty rate for HS 550952. For instance, under the United States-Mexico-Canada Agreement (USMCA), yarns originating from Canada or Mexico may be eligible for a duty rate of Free. Similarly, yarns originating from countries benefiting from the Generalized System of Preferences (GSP) may also receive preferential treatment, often resulting in a Free duty rate. To claim these preferences, importers typically require a self-certified origin statement or a GSP Form A, depending on the specific agreement and originating country, such as Mexico or a designated GSP beneficiary nation.

FAQ
What are the typical import duty rates for HS code 550952, 'Yarn of synthetic staple fibres, not put up for retail sale, containing 85% or more by weight of synthetic staple fibres, other yarn, single, not put up for retail sale, mixed mainly or solely with wool or fine animal hair'?
The Most Favored Nation (MFN) duty rate for HS code 550952 can vary. For example, under the US Harmonized Tariff Schedule (HTS), the general rate is 4.00% ad valorem. However, preferential rates apply under various Free Trade Agreements (FTAs) and trade programs. For instance, goods originating 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 benefit from duty-free entry (Free). It is crucial to consult the specific tariff schedule of the importing country and verify the country of origin to determine the applicable duty rate. The USITC HTS is a primary source for US import duties.
How is the 'mixed mainly or solely with wool or fine animal hair' criterion determined for HS code 550952?
For HS code 550952, the classification hinges on the composition of the yarn. The primary component must be synthetic staple fibers, making up 85% or more by weight. The 'mixed mainly or solely with wool or fine animal hair' specification means that the remaining percentage (up to 15%) of the yarn's weight consists of wool or fine animal hair (such as cashmere, alpaca, or mohair). If the non-synthetic component is predominantly wool or fine animal hair, and the synthetic content is at least 85%, the yarn falls under this classification. If the non-synthetic component is other than wool or fine animal hair, or if the synthetic content is less than 85%, a different HS code would apply.
What documentation is typically required for importing goods classified under HS code 550952?
When importing yarn classified under HS code 550952, 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 often mandatory. This document must be issued by the competent authority of the exporting country and certify that the goods meet the rules of origin stipulated in the relevant trade agreement. Importers and customs brokers should consult the specific requirements of the importing country's customs administration and the terms of any applicable trade agreement.
Can you provide a concrete example of how import duty is calculated for HS code 550952?
Certainly. Let's assume an importer is bringing 1,000 kilograms of yarn classified under HS code 550952 into the United States, and the applicable MFN duty rate is 4.00% ad valorem. The commercial invoice value for this shipment is $5,000 USD. The duty calculation would be as follows: Duty = Invoice Value × Duty Rate. Duty = $5,000 USD × 4.00% = $200 USD. In this scenario, the importer would owe $200 USD in customs duties. If the yarn originated from a country with a preferential duty rate of Free (e.g., South Korea under the KORUS FTA), the duty payable would be $0 USD, provided all origin requirements are met and documented.
Which major trade agreements commonly offer reduced or free duty rates for HS code 550952?
Several trade agreements provide preferential duty treatment for goods classified under HS code 550952. For imports into the United States, significant agreements include the US-Australia Free Trade Agreement (AU), US-Bahrain FTA (BH), US-Chile FTA (CL), US-Colombia Trade Promotion Agreement (CO), US-Israel FTA (IL), US-Jordan FTA (JO), US-Korea FTA (KR), US-Morocco FTA (MA), US-Oman FTA (OM), US-Panama Trade Promotion Agreement (PA), US-Peru Trade Promotion Agreement (PE), and US-Singapore FTA (SG). Each agreement has specific rules of origin that must be satisfied for the preferential treatment to apply. Importers should verify eligibility and compliance with the respective agreement's provisions.
