🏭 Furan Casting Binder (Furan Resin)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand “Furan Casting Binder”?
Furan Casting Binders, primarily composed of Furan Resins, are critical chemical additives used in the foundry industry. They serve as the binding agent for sand molds and cores in metal casting. In international trade, these products are classified based on their chemical structure (amine-cured furan resins) and physical state (primary forms).
Furan Resins are a class of synthetic resins derived from furfural or furfuryl alcohol. They are thermosetting polymers known for high thermal resistance and chemical stability.
⚠️ Key Distinction Points:
- Chemical Nature: Classified under Chapter 39 (Plastics and Articles Thereof) or Chapter 38 (Miscellaneous Chemical Products) depending on whether they are considered "resins" or "chemical preparations." - Physical State: Usually supplied as viscous liquids or powders in "primary forms." - Application: Specifically for casting sands (foundry applications).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Material Attribute |
|---|---|---|---|
3909.39.00.00 |
Amino-resins, phenolic resins and polyurethanes; other | General synthetic resins, including furan resins as a subset of complex resin structures | ✅ Synthetic Resin |
3909.40.00.00 |
Epoxy resins; urea-resins; thioure-resins; polyesters | Furan resins categorized under "synthetic resins" in primary forms | ✅ Primary Form Resin |
3911.90.91.50 |
Phenolic resins; other resins, in primary forms; furan resins | Typical thermosetting resins, primary form, high thermal stability | ✅ Thermosetting Resin |
3824.50.00.10 |
Prepared binders for foundry molds and cores (wet type) | Chemical preparations specifically for wet sand casting applications | ✅ Chemical Preparation |
3911.90.45.00 |
Other organic polymers, in primary forms; specific chemical products | Organic synthetic resins, primary form, no material conflict with furan definition | ✅ Organic Synthetic Resin |
🔍 Key Reminder:
- Chapter 39 (3909/3911) is preferred if the product is sold as a raw material/resin (pure furan resin). - Chapter 38 (3824) is often used if it is a prepared mixture specifically labeled as a "foundry binder" with additives, especially for wet-type applications. - Misclassification between "Resin" and "Prepared Binder" can lead to significant duty differences and customs scrutiny.
💰 III. 2026 Latest Tariff Rate Details (Including Additional Duties, Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: From November 10, 2025 (for subsequent imports)
🎯 1. 3909.39.00.00 & 3909.40.00.00 & 3911.90.91.50 & 3911.90.45.00 —— Furan Resins (Raw Material Classification)
| Item | Content |
|---|---|
| Base Tariff | 6.5% |
| Section 301 Additional Duty | +25.0% |
| Section 122 Duty | +10.0% |
| Total Rate | 41.5% |
| Tax Calculation | CIF Value × 41.5% |
| De Minimis Exemption | ❌ Not Eligible (deny_de_minimis) |
| Legal Basis Path | USITC:3909.39.00.00 → FOOTNOTE:301 → IEEPA:122 |
📌 Explanation:
- These codes classify Furan Resin as a synthetic resin. - The 25% Section 301 duty applies to most Chinese-made chemicals and resins. - The 10% Section 122 duty is an additional safeguard measure. - Base tariff (6.5%) is relatively low, but the total burden (41.5%) is high.
🎯 2. 3824.50.00.10 —— Prepared Foundry Binders (Chemical Preparation Classification)
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 Additional Duty | +25.0% |
| Section 122 Duty | +10.0% |
| Total Rate | 35.0% |
| Tax Calculation | CIF Value × 35.0% |
| De Minimis Exemption | ❌ Not Eligible (deny_de_minimis) |
| Legal Basis Path | USITC:3824.50.00.10 → FOOTNOTE:301 → IEEPA:122 |
📌 Note:
- If the product is explicitly declared as a "Prepared Binder" (mixture/additives), it may fall under 3824. - Although the base tariff is 0%, the additional duties (35%) are still significant. - Comparison: 35% is 6.5% lower than the resin classification (41.5%). However, customs may challenge this if the product is pure resin.

| De Minimis Exemption | ❌ Not Eligible (deny_de_minimis) |
| Legal Basis Path | USITC:3911.90.45.00 → FOOTNOTE:301 → IEEPA:122 |
📌 Detail:
- This code is for specific organic polymers in primary forms. - It offers a slightly lower total rate (40.8%) compared to general resin codes (41.5%). - Requires strong technical documentation to prove it fits the "specific chemical product" definition.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (Must-Haves)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Technical Data Sheet (TDS) | ✔️ | Shows chemical composition, curing agent, and resin type. |
| ✅ Product Photo | ✔️ | Clear image of packaging, label, and product state (liquid/powder). |

| ✅ Bill of Lading / Invoice | ✔️ | Must match HS Code description exactly. |
| ✅ Foundry Application Proof | ✔️ | If claiming 3824.50.00.10, provide evidence it is a "prepared binder" for molds. |
| ✅ Safety Data Sheet (SDS) | ✔️ | Required for chemical imports. |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 “Pure Resin = 39xx, Prepared Binder = 38xx, Name Matters, Tax Changes Fast!”
| Scenario | Correct Declaration | Error Consequence |
|---|---|---|
| Pure Furan Resin | 3909.39.00.00 or 3911.90.91.50 |
Misdeclaring as binder → Potential penalty + higher tax (41.5% vs 35%) |
| Prepared Foundry Binder | 3824.50.00.10 |
Misdeclaring as resin → Lower base tax, but customs may reclassify → 41.5% |
| Specific Organic Polymer | 3911.90.45.00 |
Needs technical proof; otherwise, risk of rejection → 41.5% |
| Chemical Preparation | 3824.50.00.10 |
Must show it’s a mixture/preparation, not pure resin |
✅ 3. Special Situations Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Binders | Provide customer specs + formulation proof. Avoid vague names like "Chemical Mix." |
| Liquid vs. Powder | Both can be classified under Chapter 39, but ensure "primary form" is stated. |
| Foundry Use Only | If using 3824.50.00.10, explicitly state "Prepared Binder for Foundry Molds." |
| High-Value Shipments | Consider Advance Ruling to lock in HS Code and duty rate. |

📌 VI. Common Mistakes & Pitfall Avoidance (Blood & Tears Lessons)
❌ Mistake 1: Declaring "Furan Resin" as "Plastic Raw Material" without specifying "Primary Form"
👉 Consequence: Customs may reclassify to a higher duty code → 41.5% instead of 35%.
❌ Mistake 2: Using "Foundry Binder" for pure resin products
👉 Consequence: Discrepancy between label and declaration → Delay + Inspection.
❌ Mistake 3: Ignoring Section 122 Duties
👉 Consequence: Underpayment → Penalties + Back Taxes.
❌ Mistake 4: Vague Product Names ("Chemical A")
👉 Consequence: Customs rejection → Return or Destruction.
✅ Correct Practice:
“Furan Resin Binder for Foundry Molds, Primary Form, Chemical Preparation, Model XYZ, SDS Attached”
🎯 VII. Conclusion: Professional Declaration, Save Time, Save Money!
🎯 Remember the Mnemonic:
🔹 “Resin 39, Binder 38, Name it Right, Tax Rate Takes Flight!”
🔹 “HS Code Determines Duty, 6.5% Difference, Declare Wrong, Pay Extra!”
📌 Pro Tip:
If your Furan Casting Binder is originating from Vietnam, Mexico, or Thailand, you may qualify for IEEPA Exemptions or FTZ (Free Trade Zone) benefits, reducing duties to 0%~5%.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
