🧪 Petroleum Resin Bars (Polymer-Based Adhesives)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What Exactly Are "Petroleum Resin Bars"?
Petroleum Resin Bars are solid forms of synthetic resins derived from petroleum cracking by-products (such as C5, C9, or mixed aromatics). They are primarily used as ** tackifiers, binders, or plasticizers in the manufacturing of adhesives, sealants, inks, and coatings**.
In the context of international trade and customs classification, these bars are not classified as simple chemical raw materials (Chapter 39) if they are prepared for specific adhesive applications. Instead, they fall under Chapter 35 (Albuminoidal Substances; Modified Starches; Glues; Enzymes) because they are "Prepared Glues" or products suitable for use as glues.
⚠️ Key Distinction:
- If the resin is a raw, unmodified chemical substance intended for further polymerization → It may fall under Chapter 39 (Plastics).
- If the resin is processed, mixed, or packaged for immediate use as an adhesive (or is a key component of an adhesive system) → It falls under Chapter 35 (Glues/Adhesives).
- Note on Packaging: The classification often changes drastically if the product is packaged for retail sale under 1kg vs. industrial bulk.
📦 II. HS Code Classification Details (Based on Provided Data)
The provided data specifically highlights two HS Codes under Heading 3506 ("Prepared glues and other prepared adhesives..."). Both codes relate to adhesives based on polymers of headings 3901 to 3913 (which includes petroleum resins) or rubber.
| HS Code | Product Description | Tax Details (Base + Additional) | Total Tax Rate | Key Condition |
|---|---|---|---|---|
| 3506.91.50.00 | Adhesives based on polymers of headings 3901 to 3913 or on rubber; Other | Base: 0.0% Additional: 0.0% |
0.0% | Specific sub-category for certain polymer-based adhesives. |
| 3506.99.00.00 | Other prepared glues and adhesives; Other | Base: 2.1% Additional: 25.0% |
27.1% | General category for "Other" adhesives not specified in 3506.91. |
🔍 Critical Analysis:
- Code3506.91.50.00appears to be a specific duty-free entry for certain types of polymer-based adhesives (likely those meeting specific technical criteria under "Other" within the 3901-3913 polymer scope).
- Code3506.99.00.00is the catch-all for other prepared adhesives. It incurs a 25% additional tariff (likely Section 301 tariffs for China-origin goods) on top of the 2.1% base duty.

🛠️ IV. Customs Clearance Practical Advice (Avoiding Pitfalls)
✅ 1. Documentation Checklist (Must-Have)
| Document | Required? | Purpose |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must explicitly state: "Petroleum Resin, Solid Form, Used as Adhesive/Tackifier." |
| ✅ Ingredient Composition | ✔️ | Proof of polymer type (e.g., C5/C9 petroleum resin) to justify Chapter 35 vs. 39. |
| ✅ Intended Use Statement | ✔️ | Declare as "Prepared Adhesive" or "Component of Adhesive System" to support HS 3506. |
| ✅ Certificate of Origin (CO) | ✔️ | Essential for determining origin-based tariffs (China vs. Non-China). |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Required for chemical shipments; confirms non-hazardous status (if applicable). |
| ✅ Commercial Invoice | ✔️ | Must describe goods accurately: "Solid Petroleum Resin Bars for Adhesive Manufacturing." |
✅ 2. Classification Strategy & Declaration Tips
🔥 "Resin Bars Are Adhesives: Classify for 0%, Not 27.1%"
| Scenario | Recommended HS Code | Risk if Misclassified |
|---|---|---|
| Petroleum Resin Bars (Bulk/Industrial) | 3506.91.50.00 | If declared as "Plastic Raw Materials" (Ch 39), you may face scrutiny and potential reclassification to 3506.99.00.00 (27.1%). |
| Retail-Size Adhesive Blocks (<1kg) | 3506.91.50.00 or 3506.99.00.00 | Ensure packaging matches the "retail sale" definition if claiming specific retail codes. |
| Raw Unmodified Resin Powder | 3907.xxxx (Not in Data) | Warning: If not "prepared" for adhesive use, it might fall under Ch 39. But the provided data focuses on Ch 35. |
| Rubber-Based Adhesives | 3506.91.50.00 | Only if based on rubber or polymers 3901-3913. |
📌 Key Insight:
- The difference between 0% and 27.1% is massive.
- You must prove that the petroleum resin bars are "prepared glues" or products suitable for use as glues.
- If the bars are just raw resin blocks without any binding/adhesive formulation, customs may challenge the Chapter 35 classification. However, if they are marketed as adhesive components, 3506.91.50.00 is the most beneficial code provided.
✅ 3. Special Handling for De Minimis (Section 321)
| Condition | Outcome |

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) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — 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 — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
