HS 510710 Containing 85 % or more by weight of wool
Quick Answer: Yarn of wool, containing 85% or more by weight of wool, enters the UK at 2.00%, the EU at 3.80%, and the US at 6% under the Most Favored Nation (MFN) tariff. This classification specifically applies to spun yarns composed predominantly of wool fibers. Importers should be aware of potential preferential duty rates available under Free Trade Agreements for certain origins into the US. Exporters should ensure accurate declaration of wool content to avoid misclassification. CustomTariffs aggregates this data to assist in trade compliance.

How to Classify This HS Code?
What products does HS 510710 cover?
This subheading covers yarn spun from wool, containing 85% or more by weight of wool, as defined by the World Customs Organization's Harmonized System (WCO HS) Nomenclature. This includes single, multiple (folded) or cabled yarns, whether or not put up for retail sale. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that the critical factor for classification under 510710 is the wool content exceeding 85% by weight, distinguishing it from yarns with lower wool percentages or those primarily composed of other fibers.
What falls outside HS 510710?
The following products are excluded from HS 510710: yarns containing less than 85% by weight of wool, which would typically fall under HS 510720 or other headings depending on the predominant fiber. Also excluded are yarns of wool mixed with other fibers where wool is not the predominant component by weight, and yarns of fine animal hair (e.g., cashmere, alpaca) unless they meet the 85% wool threshold and are not specifically classified elsewhere. For instance, yarns of 70% wool and 30% synthetic fiber would not be classified here.
What are common classification mistakes for HS 510710?
A common error is miscalculating the wool content by weight, especially when blends are involved. Importers may overlook the requirement for the wool to constitute 85% or more *by weight*, not by volume or by number of fibers. Another mistake is failing to consider whether the yarn is specifically classified under another heading, such as those for fine animal hair, if the wool content is high but the material is primarily from a different animal. Adherence to General Rule of Interpretation (GRI) 1 is crucial for correct classification.
How should importers classify products under HS 510710?
The correct procedure for classifying products under HS 510710 involves obtaining a detailed fiber composition analysis from the manufacturer, specifically stating the percentage by weight of wool. Importers and customs brokers must then consult the relevant tariff schedule, such as the USITC HTS or the UK Trade Tariff, to verify that the yarn meets the 85% wool content criterion and is not otherwise excluded. Documentation confirming the fiber content is essential for customs clearance.
How is the duty calculated for products under HS 510710?
A shipment of 100 kilograms of 100% wool yarn, declared at a customs value of $1,500 USD, would attract a US duty of $60.00. This is calculated using the Most Favored Nation (MFN) duty rate of 4% ad valorem (0.04 × $1,500 USD = $60.00). This calculation is based on the declared value and the MFN rate published in the USITC Harmonized Tariff Schedule for subheading 510710.00.00.
Which trade agreements reduce duties for HS 510710?
Several free trade agreements may reduce the applicable duty rate for HS 510710, including the United States-Mexico-Canada Agreement (USMCA), which can provide for duty-free entry for qualifying originating goods from Canada and Mexico. The UK's Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates. To claim these preferences, importers typically require a valid origin declaration or certificate, such as a USMCA Certificate of Origin or a CPTPP Certificate of Origin, depending on the specific agreement and originating country.

FAQ
What are the typical import duty rates for HS code 510710, 'Wool yarn, not put up for retail sale, containing 85 % or more by weight of wool, carded, combed or otherwise processed for spinning'?
The Most Favored Nation (MFN) duty rate for HS code 510710 can vary by importing country. For example, in the United States, the MFN rate is typically 3.80% ad valorem. In the European Union, under the TARIC system, the rate can also be 3.80% ad valorem, though specific preferential rates may apply. The United Kingdom's Trade Tariff also lists a rate of 3.80% ad valorem for non-preferential imports. Always consult the specific tariff schedule of the destination country for the most accurate and up-to-date rates.
How is the '85 % or more by weight of wool' criterion for HS 510710 determined, and what documentation is needed to prove it?
The classification under HS 510710 hinges on the wool content being 85% or more by weight. This is typically verified through a laboratory analysis certificate or a manufacturer's declaration. The certificate should clearly state the fiber composition of the yarn. Importers should be prepared to provide this documentation to customs authorities upon request to substantiate the classification and ensure compliance. This ensures the yarn is correctly identified as predominantly wool and not a blended yarn falling under a different HS code.
What common trade agreements offer preferential duty rates for HS code 510710, and how can importers benefit?
Several trade agreements can provide preferential duty rates for HS code 510710. For instance, under agreements like the US-Australia Free Trade Agreement (AU), US-Bahrain (BH), US-Chile (CL), US-Colombia (CO), US-Israel (IL), US-Jordan (JO), US-Korea (KR), US-Morocco (MA), US-Oman (OM), US-Peru (PE), US-Singapore (SG), and others, imports of this product may be eligible for duty-free entry (0% ad valorem). To benefit, importers must possess a valid Certificate of Origin issued by the exporter, demonstrating that the goods meet the rules of origin stipulated in the respective trade agreement. This requires careful documentation and adherence to the agreement's specific requirements.
How is the import duty for HS code 510710 calculated, and can you provide an example?
The import duty for HS code 510710 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if a shipment of wool yarn (HS 510710) has a customs value of $10,000 USD and the applicable MFN duty rate is 3.80%, the duty calculation would be: $10,000 (Customs Value) × 0.0380 (Duty Rate) = $380 USD. This amount represents the basic customs duty. Additional taxes or fees, such as merchandise processing fees or excise taxes, may also apply depending on the importing country's regulations.
Are there specific requirements for 'wool yarn, not put up for retail sale' under HS 510710, and how does this differ from yarn sold directly to consumers?
Yes, the 'not put up for retail sale' designation is crucial for HS 510710. This typically means the yarn is supplied in bulk packaging, such as large cones, skeins, or hanks, intended for further processing by manufacturers (e.g., in textile mills for weaving or knitting) rather than for direct sale to individual consumers in small, consumer-ready packages. If the yarn is packaged for retail sale (e.g., in small balls or skeins with labels for consumer purchase), it would likely be classified under a different HS code, such as 510720 (for other wool yarn put up for retail sale) or a code specific to retail packaging. Customs authorities will examine the packaging and intended use to ensure correct classification.
