π I. Product Definition & Classification: What Exactly Is "Thermoplastic Petroleum Resin"?
Thermoplastic Petroleum Resin is a critical industrial raw material used extensively in adhesives, sealants, coatings, and rubber compounding. In international trade, it is generally classified under Chapter 39 (Plastics and Articles Thereof), specifically within Heading 3907β3911.
The key to correct classification lies in the chemical structure and state of material: * Thermoplastic vs. Thermosetting: Your product is explicitly Thermoplastic. This excludes Heading 3911 (which primarily covers polyurethanes and certain thermosetting resins like phenolics or epoxy resins in specific forms), unless the specific resin type falls under the residual categories of 3911.90. * Primary Shape: The input data suggests forms like "moldable materials" or "primary shapes," which guides us toward Headings 3907 (Polyacetals, other polyethers, epoxies, polyphenylene oxides, polycarbonates, alkyd resins, polyallyl esters, and petroleum resins unless classified elsewhere) or 3909 (Amino-resins, phenolic resins, polyurethanes, petroleum resins).
β οΈ Critical Distinction:
- If the resin is a simple hydrocarbon resin derived from petroleum fractions (C5/C9 cuts) and is not further chemically modified into a complex polymer like an epoxy or polyester, it often falls under 3907 or 3909.
- However, if it is a specific thermoplastic phenolic or urea-formaldehyde based petroleum resin, it may fall under 3911.
- Data Insight: The provided data lists both 3911 (Thermosetting/Moldable) and 3907/3909 (Resin class). Note that "Thermoplastic" in the prompt might be a user descriptor for "re-meltable," but HS codes often classify based on the chemical family (e.g., Phenolic resins are thermosetting, but if labeled "thermoplastic phenolic," it gets tricky). Let's look at the specific codes provided.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided <DATA>, here are the specific HS Codes and their detailed explanations. Note that while the user input says "Thermoplastic," the HS codes provided in the data include 3911 (often Thermosetting) and 3907/3909 (General Resins). We must map the user's "Adhesive Base Material" to these specific entries.
| HS Code | Product Description | Applicability Scenario | Why This Code? |
|---|---|---|---|
3911.90.45.00 |
Petroleum Resin, Thermosetting Moldable Material, Original Shape | Moldable blocks/powders of petroleum-based resins, specifically classified under "Other" in 3911. | Despite "Thermoplastic" in user query, if the resin is a modified phenolic or specific thermosetting type used in adhesives, this code is used for moldable forms. The data explicitly links this code to "Petroleum Resin, Thermosetting Moldable Material." |
3907.99.50.50 |
Petroleum Resin Moldable Material, Resin Class, Primary Shape | General petroleum resins (non-polyacetal/polyether/epoxy/PC/PPO/Alkyd/Polyallyl) in primary forms. | If the resin is a simple hydrocarbon petroleum resin (e.g., C5/C9 hydrocarbon resin) not fitting 3907.10-89 exclusions, it falls here. It is a catch-all for other resins. |
3909.40.00.00 |
Petroleum Resin Moldable Material, Resin Class, Primary/Semi-Finished | Specifically for Amino-resins or Phenolic resins if classified under 3909. Note: 3909.40 is typically for Amino-resins. If the petroleum resin is an urea-formaldehyde type, it goes here. | Petroleum resins that are amino-based or phenolic-based (if 3909.39 is not more specific) fall here. The data links this to "Petroleum Resin... Resin Class." |
3909.39.00.00 |
Petroleum Resin Moldable Material, Primary Shape/Semi-Finished | Phenolic resins and resins based on them. | If the adhesive base is a phenolic resin (common in adhesives), it falls under 3909.39. This is distinct from simple hydrocarbon resins (3907). |
π Key Observation from Data:
- 3911.90.45.00 and 3907.99.50.50 / 3909.40.00.00 / 3909.39.00.00 all share similar tax rates (40.8% - 41.5%).
- The distinction is chemical.
- Simple Hydrocarbon Resin β Likely 3907.99.50.50 (or 3901-3906 if polymeric, but "petroleum resin" usually implies the tackifier type, which is often 3907.99 if not specified).
- Phenolic Resin (Petroleum-derived) β 3909.39.00.00.
- Thermosetting Moldable Petroleum Resin (General) β 3911.90.45.00.

| β Product Photos (Bulk & Label) | βοΈ | Show state (pellets, powder, block). Label must match HS description. |
| β Commercial Invoice | βοΈ | Must clearly state: "Petroleum Resin, [Type], for Adhesive Use." Avoid vague terms like "Chemical Glue Base." |
| β Supply Chain Documentation | βοΈ | Proof of origin. If re-packaged, ensure no Chinese content is hidden. |
| β Third-Party Lab Report | βοΈ | Recommended to prove it is Petroleum-Based and not synthetic polymer (like PP/PE which have different rates). |
β 2. Declaration Tips (Key Mnemonics)
π₯ βName Specific, State Clear, Avoid βGlueβ Trap, Tax Cut Half!β
| Situation | Correct Declaration | Wrong Practice |
|---|---|---|
| Simple Hydrocarbon Resin | "C5/C9 Hydrocarbon Petroleum Resin, Pellets, Primary Shape" β 3907.99.50.50 | Calling it "Adhesive Glue" β Could be misclassified as 3506 (10%+taxes) or rejected. |
| Phenolic Resin | "Phenolic Resin, Powder, Thermosetting, Primary Shape" β 3909.39.00.00 | Calling it "Thermoplastic" β Causes customs confusion and delay. |
| Moldable Block | "Petroleum Resin, Thermosetting Moldable, Block" β 3911.90.45.00 | Calling it "Plastic Pellets" β Wrong form factor, potential penalty. |
| Adhesive Product (Final) | "Liquid Adhesive, Contains 30% Resin" β 3506.91.00.00 | Declaring pure resin when it's a finished adhesive β Severe Penalty. |
β 3. Special Cases
| Scenario | Handling Advice |
|---|---|
| "Thermoplastic" vs. "Thermosetting" | If the product softens when heated but does not cure chemically, it is thermoplastic (likely 3907 or 3911 residual). If it cures irreversibly, it is thermosetting (likely 3909 or 3911). Be precise! |
| Blended Resins | If mixed with solvents or other polymers, it may no longer be "Primary Shape Resin" and could fall under 3215 (Ink/Primer) or 3506 (Adhesive). Check if it's a "mixture" vs. "pure resin." |
| Section 122 (10%) | This applies to most chemical imports from China. Ensure your HS code is correctly classified to avoid double counting or missing exemptions. |
π V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Base Tariff | Surcharge (China) | Total Est. | Notes |
|---|---|---|---|---|---|
| πΊπΈ USA | 3907.99.50.50 |
6.5% | +35% (301+122) | 41.5% | High barrier. Verify "Petroleum" origin. |
| πΊπΈ USA | 3911.90.45.00 |
5.8% | +35% (301+122) | 40.8% | Slightly lower base, same surcharge. |
| π¨π³ China | 3907.99.50.50 |
6.5% | 0% | 6.5% | No surcharge. |
| πͺπΊ EU | 3907.99 |
6.5% | 0% (if MFN) | 6.5% | Check for anti-dumping on specific resins. |
| π¬π§ UK | 3907.99 |
6.5% | 0% | 6.5% | Post-Brexit rules apply. |
π Conclusion:
- The US imposes high effective tariffs (40-41.5%) on these materials.
- Classification is critical: A slight difference between 3907, 3909, and 3911 can change the base rate (5.8% vs. 6.5%), but the surcharge (35%) dominates.
- Strategy: If you can prove the material is not subject to Section 301 (e.g., certain exemptions or non-China origin), costs drop dramatically. Otherwise, factor in ~41% duty.
π VI. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Calling it "Plastic Pellets" without specifying Petroleum Resin
π Result: Customs may classify under general plastics (3901-3914) with different tax rates, leading to back taxes if deemed incorrect.
β Error 2: Mislabeling Thermosetting as Thermoplastic
π Result: Wrong HS code (3907 vs. 3909/3911). Penalties for misdeclaration.
β Error 3: Ignoring Section 122
π Result: Under-declaring tax by 10%. Audits and fines.
β Error 4: Declaring "Adhesive" when it's a "Resin Base"
π Result: Adhesives (3506) have different rules. If it's a pure resin, use 3907/3909/3911. If it's a pre-mixed adhesive, use 3506.
β Correct Practice:
"Petroleum Hydrocarbon Resin, C5/C9 Type, Thermoplastic, White Pellets, Primary Shape, For Adhesive Manufacturing, Made in China"
π― VII. Conclusion: Professional Declaration, Cost Control, Efficiency!
π― Remember the Mnemonic:
πΉ "Resin State, Code Changes, 3907/09/11, Tax is High, Declare Right, Save Time!"
πΉ "Thermoplastic vs. Thermosetting, Choose HS Wisely, 41% Tax is Real, Don't Guess!"
π Tips:
- If your petroleum resin is derived from bio-sources or non-Chinese origin, it may qualify for lower or zero tariffs under IEEPA exemptions.
- Apply for a Binding Tariff Information (BTI) or Advance Ruling from US CBP before shipping to lock in the HS code.
- Ensure your Technical Data Sheet explicitly states the chemical family (e.g., "Hydrocarbon," "Phenolic," "Amino") to support your HS code choice.

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