HS 550630 Acrylic or modacrylic

Quick Answer: Acrylic or modacrylic staple fibres, not carded or combed, imported under HS 550630 enter the UK at 0.00%, the EU at 4.00% ad valorem, and the US at 5.00% ad valorem under the Most Favoured Nation (MFN) rate, with preferential rates available for certain trading partners. This HS code specifically covers synthetic staple fibres made from acrylic or modacrylic polymers, which are processed into short, discrete lengths suitable for spinning into yarn. Importers should be aware of the varying MFN duty rates across major markets and investigate potential free trade agreement benefits. According to CustomTariffs data, understanding these tariff differences is crucial for optimizing landed costs.

How to Classify This HS Code?

```html

What products does HS 550630 cover?

This subheading covers acrylic or modacrylic staple fibres, carded, combed or otherwise processed for spinning, but not spun. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes fibres that have undergone mechanical processing such as carding and combing to align them for spinning into yarn. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC system align with this definition, specifying that these are prepared fibres of acrylic or modacrylic polymers, ready for the next stage of textile production.

What falls outside HS 550630?

The following products are excluded from HS 550630: spun acrylic or modacrylic fibres, which have already been twisted into yarn, and continuous filament tow of acrylic or modacrylic. Also excluded are acrylic or modacrylic fibres that have not been carded, combed, or otherwise processed for spinning, as well as waste and garnettings of these materials. For instance, acrylic yarn (HS 5509) or acrylic staple fibres in their raw, unprocessed state would be classified elsewhere.

What are common classification mistakes for HS 550630?

A common error is misclassifying acrylic or modacrylic fibres that have undergone further processing beyond carding or combing but have not yet been spun into yarn. For example, if the fibres are felted or bonded, they may fall under different headings. Additionally, confusion can arise with synthetic staple fibres of other materials, such as polyester or nylon, which are classified under different HS codes within Chapter 55, requiring careful examination of the polymer composition as per General Rule of Interpretation (GRI) 1.

How should importers classify products under HS 550630?

The correct procedure for classifying products under HS 550630 involves confirming that the material is indeed acrylic or modacrylic staple fibre. Importers and customs brokers must verify that the fibres have been carded, combed, or otherwise processed for spinning but are not yet spun. Reviewing the manufacturer's specifications, technical data sheets, and product samples is crucial. Cross-referencing with the official tariff schedules of the importing country, such as the USITC HTS or the UK Trade Tariff, will confirm the correct classification.

How is the duty calculated for products under HS 550630?

A shipment of 1,000 kilograms of carded acrylic staple fibre, declared at a customs value of $2,500 USD, would attract a US duty of $125.00. This is calculated using the Most Favoured Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value. The calculation is $2,500 USD × 0.05 = $125.00. This rate is published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) under subheading 5506.30.0000.

Which trade agreements reduce duties for HS 550630?

Several free trade agreements may reduce the applicable duty rate for HS 550630. For goods originating in Canada or Mexico, the United States-Mexico-Canada Agreement (USMCA) may provide for duty-free entry. For goods originating in the United Kingdom, the UK-US Free Trade Agreement (if enacted and applicable to this product) or similar bilateral agreements could offer preferential rates, potentially "Free." Documentation required typically includes a USMCA Certificate of Origin or a self-certified origin statement, depending on the specific agreement and jurisdiction.

FAQ

What are the standard import duty rates for HS code 550630 (Acrylic or modacrylic staple fibres, not carded or combed)?

The standard Most Favored Nation (MFN) duty rate for HS code 550630 is 5.00% ad valorem. However, specific preferential duty rates apply under various Free Trade Agreements (FTAs). For example, goods originating from Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), Singapore (SG), and the United States (US) may benefit from duty-free entry (0.00%). It is crucial to consult the relevant tariff schedule for the importing country and provide proof of origin to claim preferential treatment. The UK Trade Tariff, for instance, lists a 0.00% duty for goods from various partner countries under specific conditions.

How is the import duty for HS code 550630 calculated, and can you provide an example?

The import duty for HS code 550630 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 5.00% and you import 1,000 kilograms of acrylic staple fibers with a declared customs value of $2,000 USD, the duty calculation would be: 5.00% of $2,000 USD = $100 USD. This amount would be payable to customs authorities. If a specific duty or a compound duty (combination of ad valorem and specific) applies, the calculation would differ accordingly. Always verify the exact duty calculation method with the importing country's customs authority.

What are the classification criteria for HS code 550630, and what distinguishes acrylic or modacrylic staple fibers?

HS code 550630 specifically covers 'Acrylic or modacrylic staple fibres, not carded or combed'. The key criteria for classification under this code are: 1. Material Composition: The fibers must be predominantly composed of acrylic polymers (polyacrylonitrile) or modacrylic polymers (copolymers where the polymer contains at least 35% acrylonitrile units, but less than 85%). 2. Form: The fibers must be in 'staple fiber' form, meaning they are cut to a specific length, typically ranging from a few centimeters to several decimeters. 3. Condition: The fibers must not be carded or combed. Carding and combing are processes that align and further refine staple fibers, preparing them for spinning. If the fibers have undergone these processes, they would be classified under a different HS code (e.g., 5507.00 for carded or combed staple fibers).

What documentation is typically required for importing goods under HS code 550630?

To import goods classified under HS code 550630, standard customs documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list specifying the contents of each package; and a bill of lading or air waybill for transportation. If claiming preferential duty rates under an FTA, a Certificate of Origin or a declaration of origin compliant with the specific trade agreement is mandatory. Depending on the importing country and the nature of the goods, additional certifications related to safety, quality, or environmental standards might be necessary. Importers and customs brokers should consult the specific import regulations of the destination country.

Which major trade agreements offer preferential duty rates for HS code 550630, and what are the general requirements to benefit?

Several major trade agreements provide preferential duty rates, often resulting in duty-free entry (0.00%) for goods under HS code 550630. Examples include agreements like the USMCA (United States-Mexico-Canada Agreement), CAFTA-DR (Dominican Republic-Central America Free Trade Agreement), and various bilateral agreements such as those between the EU and its partner countries, or the UK and its trade partners. To benefit from these preferential rates, the acrylic or modacrylic staple fibers must meet the 'rules of origin' stipulated in the specific trade agreement. This usually means the goods must be considered originating from the partner country, often demonstrated by a certain percentage of local content or specific manufacturing processes performed within the originating country. A valid Certificate of Origin is typically required as proof.
