HS 580640 Fabrics consisting of warp without weft assembled by means of an adhesive (bolducs)
Quick Answer: Fabrics consisting of warp without weft assembled by means of an adhesive, commonly known as bolducs, enter the UK at 6.00%, the EU at 6.20%, and the US at a general rate of 8.35% ad valorem. This classification specifically covers fabrics where the warp threads are held together by an adhesive, without the presence of weft threads. Importers should note the significant duty rate difference for the US market compared to the EU and UK. CustomTariffs aggregates this information to aid in accurate declarations.

How to Classify This HS Code?
What products does HS 580640 cover?
This subheading covers fabrics consisting solely of warp threads, where the weft is absent and the warp threads are assembled and held together by means of an adhesive. These are commonly known as "bolducs" or non-woven fabrics formed by bonding warp yarns. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, these fabrics are characterized by their warp-predominant structure, with the warp yarns being parallel and held in place by a binder. For example, certain types of interlinings or decorative fabrics created through this bonding process fall under this classification.
What falls outside HS 580640?
The following products are excluded from HS 580640: fabrics with both warp and weft threads, even if they are loosely woven or have gaps, as these would typically be classified under other headings in Chapter 58 or Chapter 50-55. Also excluded are fabrics where the warp threads are assembled by knitting, crocheting, or stitching, as these methods create different textile structures. For instance, non-woven fabrics produced by needle-punching or spun-bonding, which do not rely on warp threads assembled by adhesive, are classified elsewhere, often under heading 5603.
What are common classification mistakes for HS 580640?
A common error is misinterpreting the "assembled by means of an adhesive" criterion. Importers may mistakenly classify fabrics where the warp threads are held together by mechanical entanglement (like needle-punching) or by stitching, rather than a chemical or adhesive binder. According to General Interpretative Rule 1 of the Harmonized System, classification is determined by the terms of the headings and any relative Section or Chapter Notes. If the fabric is not exclusively warp threads held by adhesive, it will not meet the definition of heading 5806.
How should importers classify products under HS 580640?
The correct procedure for classifying fabrics under HS 580640 involves a thorough examination of the fabric's construction. Importers and customs brokers must confirm that the fabric consists solely of warp threads and that these threads are held together by an adhesive substance. Reviewing technical specifications, product samples, and manufacturer declarations is crucial. Consulting the official tariff schedules of the importing country, such as the USITC Harmonized Tariff Schedule (HTS) or the EU's TARIC database, will provide detailed descriptions and any specific exclusions or inclusions for this subheading.
How is the duty calculated for products under HS 580640?
A shipment of 1,000 square meters of a decorative bolduc fabric, declared at a customs value of $5,000 USD, would attract a US duty of $250.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value. The calculation is: 5.0% × $5,000 USD = $250.00. This rate is published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) under subheading 5806.40.0000.
Which trade agreements reduce duties for HS 580640?
Several free trade agreements may reduce the applicable duty rate for HS 580640, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating fabrics from Canada or Mexico can enter the United States duty-free. To claim this preference, a valid USMCA Certificate of Origin is typically required. Additionally, the Generalized System of Preferences (GSP) may offer reduced or zero duties for eligible products from certain developing countries, requiring documentation like a GSP Form A.

FAQ
What are the typical import duty rates for HS code 580640 (bolducs)?
The Most Favored Nation (MFN) duty rate for HS code 580640, which covers fabrics consisting of warp without weft assembled by means of an adhesive (bolducs), is generally around 6.00% ad valorem in many major economies. For example, the U.S. tariff rate is 6.00% ad valorem. However, preferential rates under Free Trade Agreements (FTAs) can significantly reduce or eliminate these duties. For instance, under agreements 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, the duty rate is often Free. It is crucial to consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment, as rates can vary based on origin and specific trade agreements. Always refer to official sources like the USITC Tariff Schedule, EU TARIC, or UK Trade Tariff for the most accurate and up-to-date information.
How is the 'warp without weft assembled by means of an adhesive' criterion for HS 580640 determined?
HS code 580640 specifically covers 'bolducs,' which are fabrics characterized by the absence of weft yarns. Instead, the warp yarns are held together and assembled using an adhesive. This means the fabric's structure relies solely on warp threads, with an adhesive substance providing cohesion and form, rather than traditional weaving where warp and weft interlace. Importers must ensure that the product's construction meets this definition. Documentation from the manufacturer detailing the production process, including the absence of weft and the use of adhesive, is essential for customs classification. This distinguishes bolducs from woven fabrics (Chapter 50-55) or knitted fabrics (Chapter 60).
What documentation is typically required for importing goods classified under HS 580640?
When importing goods classified under HS code 580640, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill for transportation. Crucially, to claim preferential duty rates under trade agreements, a Certificate of Origin (COO) is usually mandatory, demonstrating that the goods meet the rules of origin for the specific agreement. Manufacturers' declarations or technical specifications confirming the construction of the fabric as 'warp without weft assembled by means of an adhesive' may also be requested by customs authorities to verify classification. It is advisable for importers and customs brokers to check the specific import regulations of the destination country.
Can you provide an example of how import duty is calculated for HS 580640?
Let's assume an importer is bringing 1,000 square meters of bolducs into the United States, where the MFN duty rate for HS 580640 is 6.00% ad valorem. If the declared value of the 1,000 square meters is $5,000 USD, the import duty would be calculated as follows: Duty = Value × Duty Rate. In this case, Duty = $5,000 USD × 6.00% = $300 USD. If the tariff were based on a unit of quantity (e.g., per square meter), the calculation would be Rate per Unit × Quantity. For example, if the rate was $0.50 per square meter, the duty would be $0.50/sqm × 1,000 sqm = $500 USD. It is important to note that some tariffs may have both ad valorem and specific duty components, or the importer may be subject to different rates based on origin or preferential trade agreements.
Which common trade agreements offer preferential duty rates for HS 580640?
Several common trade agreements provide preferential duty rates, often resulting in Free entry, for goods classified under HS code 580640. Examples include agreements between the United States 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). The European Union also has numerous Free Trade Agreements with various countries that may offer reduced or zero duties on such textiles. To benefit from these preferential rates, importers must ensure the goods meet the specific rules of origin stipulated in the relevant trade agreement and possess the required documentation, such as a valid Certificate of Origin. Always verify the specific terms and conditions of each trade agreement with the customs authority of the importing country.
