🌟 Modacrylic Staple Fiber Blend – HS Code & Tariff Guide 2026 | Full Customs Clearance Strategy

📌 I. Product Definition & Classification: What Is "Modacrylic Staple Fiber Blend"?

Modacrylic Staple Fiber Blend refers to a short-length synthetic fiber (staple fiber) made from modified acrylic (modacrylic), typically blended with other fibers such as wool, fine animal hair, or other synthetic fibers. These blends are widely used in textiles for apparel, upholstery, and industrial applications due to their softness, warmth, flame resistance, and dyeability.

⚠️ Key Classification Clues: - "Staple fiber" → short, discontinuous fibers (not yarn or filament) - "Modacrylic" → chemically modified acrylic fiber, often with vinyl chloride content - "Blend" → mixed with other fibers (e.g., wool, cotton, polyester), especially with wool or fine animal hair - "Short fiber" → fits the definition of "staple" in textile classification

🔍 Critical Insight:
The exact HS code depends on material composition, fiber length, and whether it's blended with wool or fine animal hair. Misclassification leads to severe penalties, delays, or rejections.

📦 II. HS Code Classification Breakdown (2026 Updated Tariff Schedule)

✅ Summary of Matching Logic: - If blended with wool or fine animal hair → 5509.61.00.00 (highest tax: 48.2%) - If blended with non-wool fibers (e.g., polyester, cotton) → 5509.62.00.00 (47.0%) or 5516.93.00.90 (43.5%) - If pure modacrylic staple fiber (no blend) → 5503.30.00.00 or 5503.90.90.00 (39.3%) - If uncertain or no specific match → 5503.90.90.00 (fallback under "other synthetic staple fibers")

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (inclusive)
✅ Legal Basis: U.S. Trade Act 301, IEEPA, and Section 122 of the Trade Act

🎯 1. 5516.93.00.90 – Mixed Modacrylic Staple Fiber (Non-Wool Blend)

📌 Why This Applies:
- The fiber is modacrylic, short (staple), and blended with other fibers, but not wool → fits 5516.93.00.90
- No wool blend → cannot use 5509.61.00.00
- Not pure modacrylic → cannot use 5503.30.00.00

🎯 2. 5509.62.00.00 – Modacrylic Staple Fiber (Blended, Not Wool)

📌 Why This Applies:
- Modacrylic + staple fiber + mixed with other fibers → fits 5509.62.00.00
- Not blended with wool → not 5509.61.00.00
- Higher base rate than 5516.93.00.90 due to material specificity

🎯 3. 5509.61.00.00 – Modacrylic Staple Fiber Blended with Wool or Fine Animal Hair

📌 Why This Applies:
- Modacrylic staple fiber + blended with wool or fine animal hair → exactly matches this code
- No alternative – this is the most precise match
- Highest tax rate due to wool blend + modacrylic + Chinese origin

🎯 4. 5503.30.00.00 – Modified Acrylic (Modacrylic) Staple Fiber (No Blend)

📌 Why This Applies:
- Pure modacrylic staple fiber, no blend → fits 5503.30.00.00
- Lower base rate → most favorable if no blending occurs
- Best for cost control if fiber is not blended

🎯 5. 5503.90.90.00 – Other Synthetic Staple Fibers (Fallback)

📌 Why This Applies:
- Used when no more specific code fits
- "Other" category – applies if fiber is synthetic, staple, but not specifically modacrylic
- Use only when uncertain – not ideal for precise classification
