Medium Density Polyethylene Granules

🧪 MDPE Granules (Medium Density Polyethylene)

🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 I. Product Definition & Classification: Do You Really Understand "MDPE Granules"?

Medium Density Polyethylene (MDPE) Granules are a type of thermoplastic polymer. In international trade, they are primarily classified based on their density, molecular structure, and physical form (primary shape).

Key Distinctions:
Polyethylene (PE): The base material. If it’s PE, it falls under Chapter 39 (Plastics and Articles Thereof). * Medium Density (MDPE): Density typically ranges between 0.926 and 0.940 g/cm³. This distinguishes it from LDPE (Low Density) and HDPE (High Density). * Form: "Granules," "Pellets," or "Beads" in their initial form are considered "Primary Forms" (raw materials), not finished plastic articles. * Processing Grade: If specified as "Injection Molding Grade" (注塑级), it implies specific viscosity/flow properties but does not* change the basic HS code structure for raw materials, though it may affect the specific sub-heading selection within the code.

⚠️ Critical Classification Point:
- If it is PE with Medium Density → Generally falls under 3901.20 or 3901.10 depending on the specific statutory definition of "Medium Density" in the destination country's tariff schedule.
- If it is PE in Primary Form (Granules/Powder) → It is not a finished article (like pipes or sheets), which would fall under 3917, 3925, etc.

📦 II. HS Code Classification Details (Based on Provided Data)

According to the provided, the following HS Codes are relevant for MDPE Granules (Injection Molding Grade/Primary Form). Note that the US HTSUS structure often places PE based on density and copolymer type.

🔍 Important Data Integrity Note:
The provided contains technical inconsistencies in standard HS Code definitions: 1. HS 3901 is for Polyethylene (PE).
2. HS 3902 is for Polypropylene (PP) and other olefin polymers.
3. HS 3916 is for Rod, Bar, and Sheet of plastics, shaped during molding, not granules/powders (which are Chapter 3901/3902).

However, per instructions, we must use the provided exactly as is. The classification logic below follows the provided mapping, but you should verify with a customs broker because 3902.90.00.50 and 3916.10.00.00 are likely incorrect for "Granules" of Polyethylene in real-world US HTSUS. The most accurate codes for PE Granules are usually in 3901.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Duties & Policy Surcharges)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025/2026 Tariff Schedule

🎯 1. Codes 3901.90.90.00, 3901.10.50.30, 3902.90.00.50 — MDPE Granules (Primary Form)

📌 Explanation:
- Base 6.5%: Standard Most Favored Nation (MFN) rate for certain polyethylene articles.
- 25% Section 301: Imposed on Chinese goods under the "China Trade Remedy" program. Applies to plastics/polymer granules from China.
- 10% Section 122: A specific additional tariff mentioned in the data (likely related to specific trade remedy actions or emergency powers).
- Total 41.5%: This is a very high cost. Importers must budget for this significantly.

🎯 2. Code 3916.10.00.00 — MDPE Injection Molding Grade (Primary Form)

📌 Note:
- The base rate is slightly lower (5.8% vs 6.5%), resulting in a total of 40.8%.
- Critical Warning: As noted in Section II, HS 3916 is typically for "Rods, Bars, and Sheets." If your product is Granules, declaring it under 3916 may trigger a Customs Audit or Rejection because the form (granules) does not match the heading (shaped rods/bars). Only use this if your granules are specifically shaped into pre-formed rods/bars.

🌍 V. Global Market Comparison (2026)

📌 Conclusion:
- The USA is the most expensive market for Chinese MDPE granules due to political tariffs.
- Europe and China have significantly lower duties. Consider supply chain diversification if targeting the US market.

📌 VI. Common Mistakes & Pitfall Guide (Lessons Learned)

❌ Mistake 1: Declaring PE Granules under 3902 (PP Code)
👉 Consequence: Customs rejects the entry, demands re-classification, delays shipment, and may impose penalties.
👉 Fix: Always use 3901 for Polyethylene.

❌ Mistake 2: Declaring Granules under 3916 (Rods/Bars)
👉 Consequence: Customs audit for misdescription of form. Granules are "primary forms," rods are "shaped articles."
👉 Fix: Use 3901 for granules/powders/pellets.

❌ Mistake 3: Ignoring Section 122 tariff
👉 Consequence: Underpayment of duties. The 10% surcharge is significant.
👉 Fix: Include 10% in cost calculations.

✅ Correct Action:

"Medium Density Polyethylene (MDPE) Granules, Injection Molding Grade, CAS No. [Insert CAS], Origin: China, HS Code: 3901.90.90.00, Value: $X, Tax: 41.5%"

🎯 VII. Conclusion: Precision Saves Money!

🎯 Remember the Mantra:

🔹 "PE goes to 3901, PP goes to 3902. Granules are Primary Form. China Origin Means 41.5% Tax."
🔹 "Check the Form, Check the Material, Check the Tariff. Don't get caught in a Misdeclaration Trap!"

📌 Pro Tip:

If you are importing large volumes, apply for a Section 301 Exclusion if applicable. It can save you 25% on duties.
Consult a licensed customs broker to verify the exact HTSUS code for your specific MDPE product, as the provided data contains some non-standard mappings (e.g., 3902 for PE).
