How to Classify This HS Code?
What products does HS 550941 cover?
This subheading covers other yarn, specifically those containing 85% or more by weight of synthetic staple fibres, not put up for retail sale. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes yarns spun from man-made staple fibres such as polyester, nylon, or acrylic, provided the synthetic fibre content meets the 85% threshold. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, focusing on the material composition and the absence of retail packaging.
What falls outside HS 550941?
The following products are excluded from HS 550941: yarns containing less than 85% synthetic staple fibres, yarns made from regenerated cellulosic staple fibres (like viscose or rayon) unless they also meet the 85% synthetic staple fibre rule, and yarns put up for retail sale, which are typically classified under HS 5509.51 or other relevant subheadings depending on their specific presentation and composition. Additionally, continuous filament yarns of synthetic fibres are classified under HS 5501, not heading 5509.
What are common classification mistakes for HS 550941?
A common error is misinterpreting the "85% or more by weight" requirement for synthetic staple fibres. Importers may incorrectly assume that any yarn with a significant synthetic component falls into this category without verifying the exact percentage. Another mistake involves confusing staple fibres with continuous filament yarns, which are classified separately. Adherence to General Interpretative Rule 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial.
How should importers classify products under HS 550941?
The correct procedure for classifying products under HS 550941 involves first determining the fibre composition by weight. A laboratory analysis or manufacturer's declaration is essential to confirm that synthetic staple fibres constitute 85% or more of the total weight. Next, verify that the yarn is not put up for retail sale. Finally, consult the relevant national tariff schedule, such as the USITC HTS or the UK Trade Tariff, to confirm the specific subheading and any associated notes or exclusions.
How is the duty calculated for products under HS 550941?
A shipment of 1,000 kilograms of 100% polyester staple fibre yarn, declared at a customs value of $5,000 USD, would attract a US duty of $150.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.0% ad valorem, applied to the declared customs value ($5,000 USD × 0.03 = $150.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 550941.
Which trade agreements reduce duties for HS 550941?
Several free trade agreements may reduce the applicable duty rate for HS 550941, 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. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for eligible goods from developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ
What is the standard Most Favored Nation (MFN) duty rate for HS code 550941 (Other yarn, containing 85% or more by weight of synthetic staple fibres)?
The standard Most Favored Nation (MFN) duty rate for HS code 550941, as per the Harmonized Tariff Schedule of the United States (HTSUS), is 4.00% ad valorem. This means the duty is calculated as a percentage of the declared value of the imported goods. For example, if 100 kg of yarn valued at $500 is imported, the duty would be 4.00% of $500, resulting in a duty of $20.00.
Are there preferential duty rates available for HS code 550941 under trade agreements?
Yes, preferential duty rates are available for HS code 550941 under various trade agreements. For instance, under the USMCA (United States-Mexico-Canada Agreement), goods originating from Canada or Mexico may be eligible for duty-free entry (0%). Other agreements, such as those with 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, also offer preferential rates, often Free (0%) or significantly reduced. Importers must ensure they have the necessary proof of origin documentation to claim these benefits.
What are the key classification criteria for HS code 550941?
The primary classification criterion for HS code 550941 is that the yarn must contain 85% or more by weight of synthetic staple fibres. Synthetic staple fibres are short lengths of synthetic material, such as polyester or nylon, cut to resemble natural fibres. The yarn can be single or multiple, and it can be put up for retail sale. If the yarn contains less than 85% synthetic staple fibres but is mixed with other materials, it would be classified under a different subheading, typically within Chapter 55, based on the predominant fibre content.
What documentation is typically required for importing goods under HS code 550941?
Standard documentation for importing goods under HS code 550941 includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill. To claim preferential duty rates under trade agreements, a Certificate of Origin or a declaration of origin compliant with the specific agreement's requirements is mandatory. For certain countries, additional import permits or certificates related to textile content or safety standards might be necessary. Always consult the specific import regulations of the destination country.
How is the duty calculated if HS code 550941 is subject to an ad valorem rate and a specific duty?
While HS code 550941 in the US typically has an ad valorem rate (e.g., 4.00%), some countries might apply a combination of ad valorem and specific duties, or have different rates. For example, if a hypothetical scenario involved a 4.00% ad valorem duty and a specific duty of $0.50 per kilogram, and you imported 100 kg of yarn valued at $500: The ad valorem duty would be 4.00% of $500 = $20.00. The specific duty would be 100 kg × $0.50/kg = $50.00. The total duty would be $20.00 + $50.00 = $70.00. It is crucial to verify the exact duty structure for the importing country and the specific HS code.
