How to Classify This HS Code?
What products does HS 550610 cover?
This subheading covers staple fibres of nylon or other polyamides, not carded or combed. According to the World Customs Organization's Harmonized System Nomenclature, this includes synthetic fibres that have been cut to a specific length, suitable for spinning into yarn. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these fibres are processed to a point where they are ready for further manufacturing into textiles, excluding those in a more raw or unprocessed state.
What falls outside HS 550610?
The following products are excluded from HS 550610: staple fibres of nylon or other polyamides that are carded or combed, as these fall under HS 5507. Additionally, continuous filament tow of nylon or other polyamides is classified under HS 5501. Fabrics, knitted or woven, made from these staple fibres are also excluded and would be classified under Chapters 50-63, depending on their construction and composition.
What are common classification mistakes for HS 550610?
A common error is misclassifying carded or combed staple fibres of nylon or other polyamides under this subheading. According to General Rule of Interpretation (GRI) 3(b), mixtures are often classified by the material giving them their essential character, but in this case, the physical state of processing (carded/combed) dictates a different heading. Importers may also mistakenly classify filament tow, which is a continuous strand, as staple fibre.
How should importers classify products under HS 550610?
The correct procedure for classifying products under HS 550610 involves verifying that the goods are indeed staple fibres of nylon or other polyamides and that they have not undergone carding or combing. Importers and customs brokers should consult the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, and review the explanatory notes for Chapter 55. Confirmation of the fibre's length and processing stage is crucial for accurate classification.
How is the duty calculated for products under HS 550610?
A shipment of 1,000 kilograms of undyed nylon staple fibre, declared at a customs value of $3,000 USD, would attract a US duty of $150.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared value ($3,000 USD × 0.05 = $150.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule for HS code 5506.10.0000.
Which trade agreements reduce duties for HS 550610?
Several free trade agreements may reduce the applicable duty rate for HS 550610, 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. The Generalized System of Preferences (GSP) may also offer reduced or Free duty rates for eligible goods from certain developing countries. Documentation required typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries.

FAQ
What are the typical import duty rates for HS code 550610, specifically for 'Discontinuous synthetic staple fibres, not carded, not combed and not otherwise processed for spinning, of nylon or other polyamides'?
The Most Favored Nation (MFN) duty rate for HS code 550610 can vary. For example, under the US Harmonized Tariff Schedule (HTS), the general rate is 3.7% ad valorem. However, preferential duty rates are available for goods originating from countries with which the US has Free Trade Agreements (FTAs) or other preferential trade programs. For instance, goods from Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), Singapore (SG) may be eligible for free entry (0.00%). It is crucial to consult the latest HTS for the specific country of origin and any applicable trade agreements. For EU imports, consult the TARIC database, and for UK imports, the UK Trade Tariff.
What are the classification criteria for HS code 550610? What makes staple fibres fall under 'nylon or other polyamides'?
HS code 550610 specifically covers discontinuous synthetic staple fibres made from nylon or other polyamides. The key classification criteria are: 1. Material Composition: The fibres must be made of synthetic polyamides, which are polymers containing repeating amide groups (-CONH-) in their main chain. This includes common types like Nylon 6 and Nylon 6,6, as well as other polyamide variants. 2. Form: The fibres must be 'discontinuous', meaning they are cut into specific lengths suitable for spinning into yarn, as opposed to continuous filaments. 3. Processing Stage: They must not be carded, combed, or otherwise processed for spinning. This means they are typically in a relatively raw, cut state, ready for the initial stages of yarn production. If fibres are carded or combed, they would likely fall under a different HS code, such as 5507.00.00 (carded, combed and otherwise processed for spinning).
How is the import duty for HS code 550610 calculated, and can you provide a numerical example?
The import duty for HS code 550610 is typically calculated on an 'ad valorem' basis, meaning it's a percentage of the declared customs value of the goods. For example, if the MFN duty rate is 3.7% ad valorem and you import 1,000 kilograms of nylon staple fibres with a declared customs value of $5,000 USD, the duty calculation would be: Duty Amount = Customs Value × Duty Rate. Duty Amount = $5,000 USD × 3.7% = $185 USD. In some cases, duties can be based on a combination of value and quantity (e.g., specific duties or compound duties), but for this code, ad valorem is common. Always verify the specific duty calculation method and rate applicable to your shipment's origin and destination.
What documentation is typically required when importing goods classified under HS code 550610?
When importing goods under HS code 550610, standard customs documentation is required, which generally includes: 1. Commercial Invoice: Detailing the seller, buyer, description of goods, quantity, unit price, total value, and currency. 2. Packing List: Providing details of the packaging, weight, and dimensions of the shipment. 3. Bill of Lading (for ocean freight) or Air Waybill (for air freight): Serving as a contract of carriage and receipt of goods. 4. Certificate of Origin (COO): This is crucial for claiming preferential duty rates under Free Trade Agreements. The COO must be issued by the competent authority of the exporting country and attest that the goods meet the rules of origin. 5. Import Declaration: Filed with customs authorities. Depending on the importing country, additional certificates related to material composition or quality may be requested. Always consult the customs regulations of the importing country and your customs broker for specific requirements.
Which common trade agreements offer preferential duty rates for HS code 550610, and how can importers leverage these?
Several trade agreements can provide preferential duty rates for HS code 550610. For example, the United States has FTAs with countries like South Korea (US-Korea Free Trade Agreement), Colombia (US-Colombia Trade Promotion Agreement), and Chile (US-Chile Free Trade Agreement), which often grant duty-free or reduced-duty access for qualifying nylon staple fibres. The European Union has numerous Association Agreements and Free Trade Agreements with countries worldwide, which can also impact duties. To leverage these agreements, importers must ensure: 1. Proof of Origin: The goods must originate from a country that is a party to the relevant trade agreement. This is typically proven by a valid Certificate of Origin (COO) or a declaration of origin on the invoice, compliant with the agreement's rules of origin. 2. Compliance with Rules of Origin: The goods must meet the specific rules of origin stipulated in the trade agreement. These rules often involve a certain percentage of regional value content or specific manufacturing processes. 3. Proper Declaration: The importer or their broker must correctly declare the preferential claim to customs authorities at the time of import. Consulting the text of the specific trade agreement and the customs regulations of the importing country is essential.
