🏗️ Tower Rosin (Colophony)
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Tower Rosin"?
Tower Rosin, also known as Colophony, is the solid residue left after distilling off the volatile liquids (turpentine) from crude gum rosin or wood rosin. It is primarily composed of abietic acid and its isomers. In international trade, it is classified not just as a chemical, but specifically by its physical form and method of production.
⚠️ Critical Distinction:
- Tower Rosin: Produced via traditional distillation in a vertical tower. It is the standard industrial form.
- Wood Rosin: Extracted from tree stumps/logs via solvent extraction.
- Liquid Rosin: Not distilled; remains in liquid state.
- Chemical Rosin: Further chemically modified (hydrogenated, polymerized, etc.).📌 Key Differentiator:
If the product is pure, unmodified, solid rosin produced by distillation of gum or wood rosin, it falls under Chapter 13. If it is chemically modified (e.g., hydrogenated rosin), it moves to Chapter 35 or Chapter 38.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Chemical Modification? |
|---|---|---|---|
1302.19.95.00 |
Vegetable saps and extracts; Rosin (Colophony) and chemically modified natural resins; Rosin (Colophony) | Standard Tower Rosin, Gum Rosin, Wood Rosin (Unmodified) | ❌ No |
1302.19.98.00 |
Other vegetable saps and extracts | Other natural resins (e.g., shellac, dammar) not classified elsewhere | ❌ No |
3506.91.90.00 |
Prepared glues and other prepared adhesives; not elsewhere specified or included; Rosin-based adhesives | Pre-mixed adhesives containing rosin | ✅ Yes (Formulated) |
3824.99.92.00 |
Prepared binding agents for metallinding molds or cores; Rosin-based binding agents | Industrial binding agents where rosin is a component | ✅ Yes (Formulated) |
🔍 Key Reminder:
- Pure Tower Rosin MUST be classified under 1302.19.95.00.
- Do NOT classify modified rosins (hydrogenated, polymerized) under 1302; they belong to Chapter 35 or 38.
- If the rosin is part of a pre-made adhesive mixture, it is classified as an adhesive, not raw rosin.
💰 III. 2026 Latest Tariff Rate Details (Including Surcharge, Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: November 10, 2025 onwards (including subsequent imports)
🎯 1. 1302.19.95.00 —— Rosin (Colophony)
| Item | Content |
|---|---|
| Base Tariff Rate | 0% (ad valorem) |
| USITC Surcharge | +25% (from USITC Footnote 9903.88.01) |
| IEEPA Surcharge | +10% (targeting China/HK products, effective Nov 10, 2025) |
| Total Tariff Rate | 35% |
| Tax Calculation | CIF Value × 35% |
| De Minimis Eligibility | ❌ Not Eligible (deny_de_minimis) |
| Legal Basis Path | IEEPA:9903.01.25 → IEEPA:9903.01.24 → USITC:1302.19.95.00 → FOOTNOTE:9903.88.01 |
📌 Explanation:
- The "USITC Surcharge 25%" originates from the "Additional Duties" under Section 301 of the U.S. Trade Act.
- The "IEEPA 10%" is the对华加征关税 (China-specific surcharge) under the International Emergency Economic Powers Act.
- Total 35%, this is a high tariff burden. Must be factored into cost calculations immediately!
🛠️ IV. Clearance Practical Advice (Combat Pitfall Guide)
✅ 1. Required Documents List (None Missing)
| Document | Mandatory | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must include: Grade (e.g., WLBL, XB, N), APHA color, Acid value, Moisture content, Source (Gum/Wood) |
| ✅ Certificate of Origin (CO) | ✔️ | Essential for determining origin. If not China, may qualify for exemptions |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | Rosin is flammable solid. Customs requires safety info for transport compliance |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Tower Rosin" or "Colophony", not vague terms like "Natural Resin" |
| ✅ Packing List | ✔️ | Detail net/gross weight, packaging type (bags, boxes, pallets) |
| ✅ Proof of Unmodified Status | ✔️ | Lab test report proving no chemical modification (hydrogenation/polymerization) occurred |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Be Specific on Grade, Declare Source, Avoid 'Glue'!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Pure Tower Rosin | 1302.19.95.00 - "Tower Rosin, Unmodified" |
Declaring as "Natural Resin" → May trigger inspection |
| Hydrogenated Rosin | 3506.91.90.00 or 3824.99.92.00 |
Declaring as "Tower Rosin" → Misclassification penalty |
| Rosin-based Adhesive | 3506.91.90.00 |
Declaring as "Raw Rosin" → Incorrect Chapter |
| Wood Rosin vs. Gum Rosin | Specify source | Generic "Rosin" → Delays for origin verification |
✅ 3. Special Case Handling
| Scenario | Handling Advice |
|---|---|
| Different Grades (e.g., WLBL, XB, N) | Declare specific grade. Higher grades (WLBL) may face different quality scrutiny |
| Bulk Shipments | Provide detailed packing list. Customs may check for mixed containers |
| Re-exported from Vietnam/Malaysia | Must prove substantial transformation. Simple transshipment doesn't exempt China origin |
| Chemical Modification Claims | Provide lab test reports. If modified, use Chapter 35/38 codes |
🌍 V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 United States | 1302.19.95.00 |
35% (China Origin) | MSDS + CO | High tariff burden |
| 🇨🇳 China | 1302.19.95.00 |
0% | - | Duty-free import for raw materials |
| 🇪🇺 European Union | 1302.19.95 |
0% | REACH Compliant | No surcharge if REACH registered |
| 🇯🇵 Japan | 1302.19.90 |
5-10% | JIS Standard | Varies by grade |
| 🇮🇳 India | 1302.19.99 |
7.5% | BIS Certification | Check current basic customs duty |
📌 Conclusion:
- The US imposes the highest effective tariff (35%) on Chinese-origin Tower Rosin.
- EU and China are the most favorable markets for clearance, provided REACH/Environmental compliance is met.
- Supply Chain Strategy: Consider sourcing from non-China origins (e.g., Vietnam, Malaysia, or South America) to mitigate US surcharges.
📌 VI. Common Errors & Pitfall Guide (Blood and Tears Lessons)
❌ Error 1: Declaring "Rosin" without specifying "Tower" or "Wood"
👉 Consequence: Customs may detain shipment for origin verification → Delay + Storage Fees
❌ Error 2: Misclassifying Hydrogenated Rosin as "Tower Rosin" (1302)
👉 Consequence: Incorrect HS code → Penalty + Back Tax + Interest
❌ Error 3: Not providing MSDS for Rosin
👉 Consequence: Rosin is flammable. Missing MSDS → Rejection by Carrier or Customs
❌ Error 4: Using vague terms like "Natural Extract" or "Plant Resin"
👉 Consequence: High suspicion of misdeclaration → 100% Inspection + Fine
✅ Correct Practice:
"Tower Rosin, Unmodified, Grade WLBL, APHA Color <40, Acid Value 170-175, Produced by Distillation, Origin: China, MSDS Attached"
🎯 VII. Conclusion: Precise Classification, Cost Efficiency!
🎯 Remember the Mantra:
🔹 "Pure Rosin is 1302, Modified is 35/38, US Tariff is 35%, Be Specific!"
🔹 "HS Code Defines Duty, Misclassification Costs Thousands, Declare Accurately!"
📌 Pro Tip:
If your Tower Rosin is originally from Vietnam, Malaysia, or South America, you may qualify for IEEPA exemption, reducing the tariff to 0%~5%.
Recommendation: Apply for an Advance Ruling from US Customs (CBP) before shipment to confirm classification and tariff liability.
📣 Immediate Action:
📞 Contact a licensed customs broker + Provide Lab Test Report + Apply for HS Code Advance Ruling
🚀 Ensure your Tower Rosin clears smoothly, escapes high tariffs, and maximizes profit!

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
