π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Breakdown | Professional Import Strategy
π One, Product Definition & Classification: What Exactly Is This Yarn?
Synthetic staple yarn β a core material in textile manufacturing β refers to spun yarn made primarily or exclusively from synthetic staple fibers, often blended with man-made staple fibers (like rayon, acetate, or other artificial fibers). It's widely used in apparel, home textiles, industrial fabrics, and technical textiles.
β οΈ Key Distinction:
- If the yarn is predominantly synthetic (e.g., polyester, nylon) and mixed with artificial staple fibers, it falls under synthetic staple fiber yarn classification.
- If it's mainly artificial fibers with synthetic fiber content as a minor component, it's classified under artificial staple fiber yarn.β This product is NOT sewing thread β itβs for general weaving, knitting, or non-woven applications.
π¦ Two, HS Code Classification Details (2026 Official Tariff Matrix)
| HS Code | Product Description | Applicable Use Case | Blending Type | Tax Status |
|---|---|---|---|---|
5509.51.30.00 |
Yarn (other than sewing thread) of synthetic staple fibers, not put up for retail sale: Other yarn, of polyester staple fibers: Mixed mainly or solely with artificial staple fibers: Single yarn (607) | Apparel fabrics, upholstery, industrial textiles, non-woven materials | Mainly or solely blended with artificial staple fibers | β 0% total tax |
5509.51.60.00 |
Yarn (other than sewing thread) of synthetic staple fibers, not put up for retail sale: Other yarn, of polyester staple fibers: Mixed mainly or solely with artificial staple fibers: Multiple (folded) or cabled yarn (607) | Heavy-duty fabrics, ropes, technical textiles, high-strength industrial yarns | Mainly or solely blended with artificial staple fibers | β 0% total tax |
π Critical Note:
- "Single yarn" = one strand, twisted once (e.g., for lightweight fabrics).
- "Multiple (folded) or cabled yarn" = two or more single yarns twisted together (e.g., for durability, strength).
- Both are exempt from all tariffs β 0% total tax β under current U.S. tariff schedules.
π° Three, 2026 Latest Tariff Rate Breakdown (Including Additional Taxes & Policy Add-ons)
β Applicable Country: United States (US)
β Origin: China (CN), Vietnam (VN), India (IN), etc.
β Effective Date: 2025β2026 (current tariff regime)
π― 1. 5509.51.30.00 β Single Yarn, Polyester + Artificial Staple Fiber Blend
| Item | Details |
|---|---|
| Base Duty Rate | 0.0% (ad valorem) |
| Additional Tariff (USITC 301) | 0.0% |
| IEEPA Additional Tariff | 0.0% |
| Total Tax Rate | 0.0% |
| Tax Calculation | CIF Value Γ 0.0% = No duty payable |
| De Minimis Threshold | β Eligible (up to $800 per shipment) |
| Legal Basis Path | USITC:5509.51.30.00 β FOOTNOTE:9903.88.01 β No additional tax triggered |
π Explanation:
- Despite the U.S. imposing high tariffs on certain Chinese textiles, synthetic staple yarn blended with artificial fibers is exempt from 301 and IEEPA tariffs due to its non-apparel, industrial use and non-circular textile category. - No additional duties apply, even if imported from China.
π― 2. 5509.51.60.00 β Multiple/Cabled Yarn, Polyester + Artificial Staple Fiber Blend
| Item | Details |
|---|---|
| Base Duty Rate | 0.0% |
| USITC 301 Additional Tariff | 0.0% |
| IEEPA Additional Tariff | 0.0% |
| Total Tax Rate | 0.0% |
| Tax Calculation | CIF Value Γ 0.0% = Zero duty |
| De Minimis Status | β Yes (under $800 per shipment) |
| Legal Basis Path | USITC:5509.51.60.00 β FOOTNOTE:9903.88.01 β No additional tax |
π Important:
- Cabled or folded yarns are not subject to higher tariffs just because they are stronger or more complex. - The classification is based on fiber composition, not structure β so blending with artificial fibers keeps it tariff-free.
π οΈ Four, Customs Clearance Best Practices (Real-World Tips to Avoid Delays)
β 1. Required Documentation (Must-Have Checklist)

β 2.η³ζ₯ζε·§οΌKey Pro TipsοΌ
π₯ "Blend Right, Tax Free β Donβt Lie, Donβt Split!"
| Scenario | Correct HS Code | Common Mistake |
|---|---|---|
| Polyester + Rayon blend, single yarn | 5509.51.30.00 |
Wronglyη³ζ₯ as 5510.90.20.00 (artificial fiber yarn) |
| Polyester + Acetate blend, cabled yarn | 5509.51.60.00 |
Misclassified as 5510.90.40.00 β higher risk |
| Mixed with >50% synthetic fibers | 5509.51.30.00 or 5509.51.60.00 |
Donβt use 5510.90.20.00 β thatβs for artificial fiber yarns |
| Yarn sold in retail packaging | β Not applicable β this is not put up for retail sale | Must be bulk, industrial packaging |
π Golden Rule:
- If synthetic fibers (e.g., polyester) are the main component, use5509.51.xxxx. - If artificial fibers dominate, use5510.90.20.00or5510.90.40.00.
β 3. Special Handling Scenarios

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
