How to Classify This HS Code?
What products does HS 521143 cover?
This subheading covers woven fabrics of cotton, containing less than 85% cotton by weight, predominantly or solely of synthetic staple fibres, and weighing more than 200 g/m², specifically those constructed in a 3-thread or 4-thread twill weave, including cross twill. According to the World Customs Organization's Harmonized System Nomenclature, this classification is determined by the fibre content, weight, and the specific weave structure, ensuring precise identification of these cotton-synthetic blends. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope for imported goods.
What falls outside HS 521143?
The following products are excluded from HS 521143: fabrics primarily of cotton (which would fall under heading 5208 or 5209), fabrics weighing 200 g/m² or less, and fabrics with weave structures other than 3-thread or 4-thread twill, such as plain weave or satin. For instance, a 100% cotton denim fabric weighing 300 g/m² would be classified under heading 5209, and a polyester-cotton blend in a plain weave weighing 150 g/m² would be classified elsewhere, typically in Chapter 55.
What are common classification mistakes for HS 521143?
A common error is misinterpreting the fibre content percentage or the weave structure. Importers may incorrectly assume a fabric is predominantly synthetic when it is not, or fail to accurately identify the twill weave. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. For example, confusing a 2/2 twill with a 3-thread or 4-thread twill can lead to misclassification, potentially resulting in incorrect duty payments.
How should importers classify products under HS 521143?
The correct procedure for classifying products under HS 521143 involves a multi-step process. Importers and customs brokers must first determine the exact fibre composition by weight, ensuring it meets the criteria of less than 85% cotton. Secondly, they must verify the fabric's weight per square meter, confirming it exceeds 200 g/m². Finally, the weave structure must be meticulously examined to confirm it is a 3-thread or 4-thread twill, including cross twill, referencing technical textile specifications and visual inspection.
How is the duty calculated for products under HS 521143?
A bolt of "Cotton-Polyester Blend Twill Fabric" weighing 500 kg and declared at a customs value of $2,500 USD would attract a US duty. Assuming an MFN duty rate of 8.5% ad valorem for this specific fabric type under the USITC Harmonized Tariff Schedule, the duty calculation would be 8.5% of $2,500, resulting in a duty amount of $212.50. This is calculated using the ad valorem rate applied to the declared customs value.
Which trade agreements reduce duties for HS 521143?
Several free trade agreements may reduce the applicable duty rate for HS 521143, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, qualifying fabrics originating from Mexico or Canada can achieve a duty rate of Free. For example, a fabric manufactured in Canada meeting the yarn-forward rule of origin would be eligible. Documentation required to claim this preference typically includes a valid USMCA certification of origin, which must be provided to customs authorities.

FAQ
What are the typical import duty rates for HS code 521143, 'Other fabrics of 3-thread or 4-thread twill, including cross twill'?
The Most Favored Nation (MFN) duty rate for HS code 521143 is typically 8.00% ad valorem in many major trading economies. However, preferential rates can significantly reduce or eliminate duties under various trade agreements. For example, goods originating from countries like 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 receive duty-free treatment or substantially lower rates. It is crucial to consult the specific tariff schedule of the importing country and verify the rules of origin for any applicable preferential treatment. Always refer to official sources such as the USITC Harmonized Tariff Schedule, the EU TARIC database, or the UK Trade Tariff for precise and up-to-date duty rates.
How is the import duty for HS 521143 calculated, and can you provide an example?
The duty for HS code 521143 is generally calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. For instance, if the MFN duty rate is 8.00% ad valorem, and the declared customs value of a shipment of these fabrics is $10,000 USD, the duty would be calculated as: $10,000 (Value) × 0.08 (Duty Rate) = $800 USD. This is the basic ad valorem calculation. Some countries may also apply other duties or taxes, such as excise duties or VAT, which are calculated separately.
What are the key classification criteria for HS code 521143?
HS code 521143 specifically covers 'Other fabrics of 3-thread or 4-thread twill, including cross twill', made from cotton. The primary classification criteria are: 1. Material: The fabric must be predominantly of cotton. 2. Weave: The fabric must exhibit a 3-thread or 4-thread twill weave, or a cross twill weave. This refers to the specific interlacing pattern of the warp and weft yarns. A twill weave is characterized by its diagonal lines on the fabric surface. 'Other' in this context means fabrics not specifically listed under more precise subheadings within heading 5211, which covers cotton fabrics of a weight exceeding 200 g/m².
What documentation is typically required for importing goods classified under HS 521143?
Standard import documentation for HS code 521143 generally includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; a bill of lading or air waybill for transportation; and potentially a certificate of origin if preferential duty rates are claimed. For cotton fabrics, specific documentation might be required by certain importing countries to verify compliance with import regulations or to confirm the origin of the cotton, especially if there are specific trade agreements or quotas in place. Importers and customs brokers should always verify the exact requirements with the customs authority of the destination country.
Which common trade agreements offer preferential duty rates for HS code 521143, and how can importers benefit?
Several trade agreements can provide preferential duty rates for HS code 521143. Examples include agreements between the US and countries like Chile, Singapore, and Australia; the EU's Economic Partnership Agreements (EPAs) with African, Caribbean, and Pacific (ACP) countries; and the UK's various trade deals post-Brexit. To benefit, importers must ensure the fabrics are 'originating' from a country party to the agreement and that they can provide a valid proof of origin, such as a certificate of origin or an origin declaration on the invoice, as stipulated by the agreement. This often requires close collaboration with the foreign supplier to obtain the necessary documentation and verify compliance with the rules of origin. Consulting the specific trade agreement text and the importing country's customs regulations is essential.
