HS 550319 Other
Quick Answer: Synthetic staple fibres, not carded or combed, not spun, of acrylic or modacrylic, not containing other materials, imported under HS 550319, enter the UK at 0.00%, the EU at 4.00% ad valorem, and the US with Most Favored Nation (MFN) rates of 25% or free, depending on specific subheadings. This residual "Other" classification applies to acrylic or modacrylic staple fibres that do not fit into more specific categories within Chapter 55. Importers should carefully verify the exact product composition and the applicable US subheading to determine the correct duty. CustomTariffs aggregates this information for compliance.

How to Classify This HS Code?
What products does HS 550319 cover?
This subheading covers other synthetic staple fibers, not carded, combed or otherwise processed for spinning, that are not asbestos. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category is for synthetic staple fibers that do not fit into more specific subheadings within 5503. For instance, the USITC Harmonized Tariff Schedule (HTS) defines this as "Other" synthetic staple fibers, implying a residual category for those not explicitly listed elsewhere, such as those derived from acrylic or modacrylic polymers.
What falls outside HS 550319?
The following products are excluded from HS 550319: synthetic staple fibers that are carded, combed, or otherwise processed for spinning, such as sliver or roving; asbestos fibers; and staple fibers of artificial origins (e.g., rayon). For example, polyester staple fiber that has undergone carding to prepare it for yarn production would be classified under a different subheading, typically within heading 5504 or 5505, depending on its specific processing and material composition.
What are common classification mistakes for HS 550319?
A common error is misinterpreting the "other" designation, leading to the incorrect classification of processed synthetic staple fibers. General Rule of Interpretation (GRI) 1 of the Harmonized System mandates that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers may mistakenly classify fibers that have undergone minimal processing, such as slight crimping or cutting to specific lengths, under this subheading when they should be classified as prepared for spinning.
How should importers classify products under HS 550319?
The correct procedure for classifying products under HS 550319 involves a thorough examination of the material's composition and processing. Importers must first determine if the fiber is synthetic and in staple form. Crucially, they must verify that the fiber has not been carded, combed, or otherwise processed for spinning. Consulting the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC database, and reviewing the explanatory notes for heading 5503 is essential for accurate classification.
How is the duty calculated for products under HS 550319?
A shipment of 1,000 kilograms of unspecified synthetic staple fiber, declared at a customs value of $2,500 USD, would attract a US duty of $125.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($2,500 USD × 0.05 = $125.00). This calculation is based on the duty rates published in the USITC Harmonized Tariff Schedule for subheading 5503.19.90.00.
Which trade agreements reduce duties for HS 550319?
Several free trade agreements may reduce the applicable duty rate for HS 550319, 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. Additionally, preferential rates may be available under the Generalized System of Preferences (GSP) for eligible developing countries, potentially offering a reduced rate or Free entry. Documentation required typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries.

What is the general import duty rate for HS code 550319 in the United States?
For HS code 550319, which covers 'Other synthetic staple fibres, not carded, combed or otherwise processed for spinning', the general Most Favored Nation (MFN) duty rate in the United States is 4.00% ad valorem.

How is the import duty for HS code 550319 calculated for a shipment to the European Union?
The duty calculation for HS code 550319 in the EU depends on the specific type of synthetic staple fibre. For example, if a shipment of 'other' synthetic staple fibres (not acrylic or polyester) is valued at €10,000 and the applicable duty rate from the TARIC database is 3.5% ad valorem, the duty would be calculated as €10,000 * 0.035 = €350. Importers and brokers must consult the EU TARIC system for the precise rate applicable to their specific product.
Are there any preferential duty rates available for HS code 550319 under trade agreements affecting the UK?
Yes, preferential duty rates may be available for HS code 550319 for imports into the UK, depending on the country of origin and any applicable trade agreements, such as the UK's Free Trade Agreement with the EU or other bilateral agreements. For instance, goods originating from certain countries might qualify for a Free (0.00%) duty rate.

What documentation is typically required when importing goods classified under HS code 550319?
When importing goods under HS code 550319, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of import and the specific nature of the 'other' synthetic staple fibres, additional documents like a certificate of origin may be necessary, especially if claiming preferential duty rates under a trade agreement. Some jurisdictions might also require specific product certifications or declarations to ensure compliance with safety or environmental standards.
What distinguishes 'other' synthetic staple fibres (HS 550319) from other synthetic staple fibre classifications?
HS code 550319 is a residual category for synthetic staple fibres that do not fall under more specific headings within Chapter 55. This includes synthetic staple fibres not carded, combed, or otherwise processed for spinning, which are not specifically classified as acrylic (5503.10), polyester (5503.20), polyamide (5503.30), or regenerated cellulose (5504 series). Classification relies on the material composition and the stage of processing. If a fibre does not meet the criteria for these more specific codes, it is generally classified under 550319. Consulting the WCO Explanatory Notes or a customs broker is advisable for definitive classification.
