๐ HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
๐ 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.
โ ๏ธ 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.).๐ 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.
๐ฆ 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) | โ No |
1302.19.98.00 |
Other vegetable saps and extracts | Other natural resins (e.g., shellac, dammar) not classified elsewhere | โ No |
3506.91.90.00 |
Prepared glues and other prepared adhesives; not elsewhere specified or included; Rosin-based adhesives | Pre-mixed adhesives containing rosin | โ 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 | โ Yes (Formulated) |
๐ 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.
๐ฐ III. 2026 Latest Tariff Rate Details (Including Surcharge, Policy Add-ons)
โ Applicable Country: United States (US)
โ Country of Origin: China (CN)
โ Effective Date: November 10, 2025 onwards (including subsequent imports)
๐ฏ 1. 1302.19.95.00 โโ 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% |

๐ Explanation:
- The "USITC Surcharge 25%" originates from the "Additional Duties" under Section 301 of the U.S. Trade Act.
- The "IEEPA 10%" is theๅฏนๅๅ ๅพๅ ณ็จ (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!
๐ ๏ธ IV. Clearance Practical Advice (Combat Pitfall Guide)
โ 1. Required Documents List (None Missing)
| Document | Mandatory | Description |
|---|---|---|
| โ Product Specification Sheet | โ๏ธ | Must include: Grade (e.g., WLBL, XB, N), APHA color, Acid value, Moisture content, Source (Gum/Wood) |
| โ Certificate of Origin (CO) | โ๏ธ | Essential for determining origin. If not China, may qualify for exemptions |
| โ Material Safety Data Sheet (MSDS) | โ๏ธ | Rosin is flammable solid. Customs requires safety info for transport compliance |
| โ Commercial Invoice | โ๏ธ | Must clearly state "Tower Rosin" or "Colophony", not vague terms like "Natural Resin" |
| โ Packing List | โ๏ธ | Detail net/gross weight, packaging type (bags, boxes, pallets) |
| โ Proof of Unmodified Status | โ๏ธ | Lab test report proving no chemical modification (hydrogenation/polymerization) occurred |
โ 2. Declaration Tips (Key Mantras)
๐ฅ "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" โ May trigger inspection |
| Hydrogenated Rosin | 3506.91.90.00 or 3824.99.92.00 |
Declaring as "Tower Rosin" โ Misclassification penalty |
| Rosin-based Adhesive | 3506.91.90.00 |
Declaring as "Raw Rosin" โ Incorrect Chapter |
| Wood Rosin vs. Gum Rosin | Specify source | Generic "Rosin" โ Delays for origin verification |
โ 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 |
๐ V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| ๐บ๐ธ United States | 1302.19.95.00 |
35% (China Origin) | MSDS + CO | High tariff burden |
| ๐จ๐ณ China | 1302.19.95.00 |
0% | - | Duty-free import for raw materials |
| ๐ช๐บ European Union | 1302.19.95 |
0% | REACH Compliant | No surcharge if REACH registered |
| ๐ฏ๐ต Japan | 1302.19.90 |
5-10% | JIS Standard | Varies by grade |
| ๐ฎ๐ณ India | 1302.19.99 |
7.5% | BIS Certification | Check current basic customs duty |
๐ 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.
๐ VI. Common Errors & Pitfall Guide (Blood and Tears Lessons)
โ Error 1: Declaring "Rosin" without specifying "Tower" or "Wood"
๐ Consequence: Customs may detain shipment for origin verification โ Delay + Storage Fees
โ Error 2: Misclassifying Hydrogenated Rosin as "Tower Rosin" (1302)
๐ Consequence: Incorrect HS code โ Penalty + Back Tax + Interest
โ Error 3: Not providing MSDS for Rosin
๐ Consequence: Rosin is flammable. Missing MSDS โ Rejection by Carrier or Customs
โ Error 4: Using vague terms like "Natural Extract" or "Plant Resin"
๐ Consequence: High suspicion of misdeclaration โ 100% Inspection + Fine
โ Correct Practice:
"Tower Rosin, Unmodified, Grade WLBL, APHA Color <40, Acid Value 170-175, Produced by Distillation, Origin: China, MSDS Attached"
๐ฏ VII. Conclusion: Precise Classification, Cost Efficiency!
๐ฏ Remember the Mantra:
๐น "Pure Rosin is 1302, Modified is 35/38, US Tariff is 35%, Be Specific!"

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
