Synthetic Rubber Sheet

🛢️ Synthetic Rubber Sheet (Clay/Powder Forms in Data)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 I. Product Definition & Classification: Understanding "Synthetic Rubber Powder"

The data provided specifically identifies "Synthetic Rubber Powder" (not sheets) as the subject of classification. In international trade, synthetic rubber is categorized based on its chemical composition (polymer type) and physical state. The data highlights two main chemical groups for powdered forms: 1. General Synthetic Rubber: Unspecified generic synthetic rubber in powder form. 2. Ethylene Polymers: Synthetic rubber derived specifically from ethylene polymers.

⚠️ Critical Distinction:
- The data explicitly lists "Powder" (粉末) forms. If you are importing Sheets, these HS codes may NOT apply directly, as sheet forms typically fall under different subheadings (e.g., 4002.99). However, based strictly on the provided , we analyze the "Powder" classifications provided.
- If your product is indeed a Sheet, please verify if it matches the description of "Ethylene Polymer" or "General Synthetic Rubber" in powder form, or if a re-evaluation of the HS code is required for sheet goods.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority对照)

| HS Code | Product Description | Applicable Scenario | Chemical Nature | |--------|----------|--------------------------| | 4002.19.00.19 | Synthetic Rubber Powder (General) | Generic synthetic rubber in powder form, not specified as ethylene-based | General Synthetic Rubber | | 4002.19.00.14 | Synthetic Rubber Powder (General) | Generic synthetic rubber in powder form, not specified as ethylene-based | General Synthetic Rubber | | 3901.90.10.00 | Synthetic Rubber Powder (Ethylene Polymer) | Specifically derived from ethylene polymers, powder form | Ethylene Polymer | | 3901.90.90.00 | Synthetic Rubber Powder (Ethylene Polymer) | Specifically derived from ethylene polymers, powder form | Ethylene Polymer |

🔍 Key Insight:
- HS Codes 4002... generally cover general synthetic rubbers. - HS Codes 3901... cover ethylene polymers (often classified under plastics/chapter 39 if not meeting the definition of rubber in Chapter 40, or depending on specific regulatory interpretations). - ⚠️ Warning: The prompt asks for "Synthetic Rubber Sheet," but the data only contains "Powder" descriptions. Do not use these codes for actual sheets without verifying the physical form.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025/2026 Period (as per data)

🎯 1. 4002.19.00.19 & 4002.19.00.14 —— General Synthetic Rubber Powder

📌 Explanation:
- These codes attract a 0% base duty, but the 35% total rate is driven entirely by punitive tariffs (Section 301 and Section 122). - Section 301 (25%): Standard US trade remedy tariff on many Chinese goods. - Section 122 (10%): Additional surcharge targeting specific categories. - Result: A high-cost entry into the US market.

🎯 2. 3901.90.10.00 —— Ethylene Polymer Powder

📌 Explanation:
- Despite being classified under Chapter 39 (Ethylene Polymers), this item is treated similarly to synthetic rubber in terms of tariffs if identified as a polymer rubber compound. - Total Rate: 35%.

🎯 3. 3901.90.90.00 —— Ethylene Polymer Powder (Other)

📌 Explanation:
- This is the most expensive category in the dataset. - It incurs a 6.5% base duty plus the 35% in surcharges. - Total Rate: 41.5%. High impact on profit margins.

🛠️ IV. Customs Clearance Practical Advice (实战避坑指南)

✅ 1. Preparation Checklist (All Required)

✅ 2. Declaration Tips (Key Mantra)

🔥 "Form Matters: Powder vs. Sheet"
- If your product is Sheet, do NOT use these HS Codes (4002.19.00.19/14, 3901.90.10/90) unless the customs authority confirms they apply to your specific sheet composition.
- Correct Description: "Synthetic Rubber Powder" or "Ethylene Polymer Powder."
- Incorrect Description: "Synthetic Rubber Sheet" (Mismatch leads to detention).

✅ 3. Special Handling

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- USA imposes 35%-41.5% tariffs on these powdered synthetic rubber/ethylene polymer goods.
- Non-US Markets typically have significantly lower base tariffs but may have other regulatory barriers (e.g., REACH in EU).

📌 VI. Common Errors & Pitfalls (Blood Lessons)

❌ Error 1: Declaring "Synthetic Rubber Sheet" but using Powder HS Codes
👉 Consequence: Customs may detain the shipment for misdescription. Risk of penalty and re-classification.
👉 Fix: Verify physical form. If Sheet, find the correct HS Code for Sheets (e.g., 4002.99 or 4008).

❌ Error 2: Ignoring Section 122 (10%)
👉 Consequence: Underpayment of duties. Audits may reveal unpaid 10% surcharge + interest.
👉 Fix: Ensure total rate calculation includes Base + 301 + 122.

❌ Error 3: Confusing Ethylene Polymer (3901) with General Rubber (4002)
👉 Consequence: 3901.90.90.00 has a 6.5% base duty, while 4002 codes have 0%. Misclassification leads to under/over payment.
👉 Fix: Conduct chemical analysis to confirm polymer type.

✅ Correct Practice:

"Synthetic Rubber Powder, 90% Ethylene Polymer, CAS No. XXXXX, Packaged in 25kg Bags, For Use in [Specific Application]."

🎯 VII. Conclusion: Precise Declaration Saves Money

🎯 Remember:

🔹 "Powder vs. Sheet: Know Your Form!"
🔹 "35-41.5% Total Duty: Plan Your Budget!"
🔹 "Ethylene Polymer? Check 3901. General Rubber? Check 4002."

📌 Tip:

If your product is truly a Sheet, these HS codes are likely incorrect. Please consult a customs broker to identify the correct HS Code for Synthetic Rubber Sheets (e.g., 4002.99.xxxx). Using powder codes for sheets can lead to severe penalties.

📣 Immediate Action:

📞 Contact a Licensed Customs Broker to verify if your "Sheet" product can legally be classified under these powder codes or if a re-evaluation is needed.
