π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π 1. Product Definition & Classification: What is "Solid Glue"?
"Solid glue" in international trade typically refers to prepared adhesives, specifically those suitable for retail sale in containers weighing 1 kg or less. The classification hinges on the chemical composition (Animal vs. Other) and the packaging (Retail-ready).
Key Distinction: * Animal Glue (3506.10.10.00): Includes casein glue, gelatin glue, etc., but excludes fish glue. This category is subject to high punitive tariffs due to its origin (China). * Other Adhesives (3506.10.50.00): Synthetic glues, plastic adhesives, or other prepared glues not specified elsewhere. These currently enjoy 0% duty.
β οΈ Critical Classification Point: * If the product is Animal-based (e.g., glue sticks, casein powder, gelatin blocks) β 3506.10.10.00 * If the product is Non-Animal/Synthetic (e.g., PVC glue, acrylic, hot melt sticks not made from animal protein) β 3506.10.50.00 * Retail Packaging Limit: Must be β€ 1 kg net weight. Larger industrial drums fall under different codes (e.g., 3506.10.90).
π¦ 2. HS Code Classification Details (2026 Latest Harmonized System)
| HS Code | Product Description | Applicable Scenario | Origin/Restriction |
|---|---|---|---|
3506.10.10.00 |
Animal Glue (Casein, Gelatin, etc.) | Retail glue sticks, animal-based craft glues, casein powders (β€1kg) | π¨π³ China Origin: High Tariff |
3506.10.50.00 |
Other Prepared Adhesives | Synthetic glues, PVC cement, acrylic adhesives, hot melt sticks (β€1kg) | π¨π³ China Origin: 0% Duty |
π Key Reminder: * Do not misclassify synthetic glue as "Animal Glue" to avoid penalties, nor "Animal Glue" as "Other" to evade taxes (customs will check ingredient lists). * "Not exceeding 1 kg" is a strict condition. If you ship a 2kg block, it may be reclassified under 3506.10.90, changing the tax logic.
π° 3. 2026 Latest Tariff Rate Breakdown (Including Additional Duties)
β Applicable Country: United States (US)
β Country of Origin: China (CN)
β Effective Date: Post-2025 Trade Policies
π― 1. 3506.10.10.00 ββ Animal Glue & Casein Glue
| Item | Content |
|---|---|
| Base Tariff Rate | 6.5% (Ad Valorem) |
| Section 301 Additional Tariff | +25.0% (Retained punitive tariff on HS 3506) |
| Total Effective Tax Rate | 31.5% |
| Tax Calculation | CIF Value Γ 31.5% |
| De Minimis Exemption | β Not Applicable (Section 301 goods are generally excluded from $800 de minimis if flagged as restricted, though specific CBP rulings vary; assume NO exemption for risk management). |
| Legal Basis Path | HTSUS:3506.10.10.00 β Section 301 List 4 β USITC Footnotes |
π Explanation: * The 6.5% is the standard MFN (Most Favored Nation) rate for prepared glues. * The 25.0% is the Section 301 retaliatory tariff applicable to many chemical products from China. * Total 31.5% is a significant cost driver. You must factor this into your landed cost.

| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% |
| Additional Tariffs | 0.0% |
| Total Effective Tax Rate | 0.0% |
| Tax Calculation | $0 |
| De Minimis Exemption | β Potentially Applicable (If value <$800 and not subject to other restrictions like anti-dumping). |
| Legal Basis Path | HTSUS:3506.10.50.00 |
π Note: * This is the zero-tariff pathway for synthetic adhesives. * Ensure your product specification sheets clearly state non-animal origin (e.g., "Polyvinyl Acetate," "Acrylic") to justify this code.
π οΈ 4. Customs Clearance Practical Advice (Risk Mitigation Guide)
β 1. Required Documentation Checklist
| Document | Mandatory? | Purpose |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must list chemical composition (e.g., "Contains 50% Gelatin" vs. "100% Acrylic"). |
| β Ingredient List | βοΈ | Critical for proving whether it is "Animal Glue" (3506.10.10) or "Other" (3506.10.50). |
| β Net Weight Declaration | βοΈ | Must explicitly state β€ 1 kg per container. |
| β Commercial Invoice | βοΈ | Description should be precise: e.g., "Synthetic PVC Adhesive, Retail Pack, 500g". |
| β Safety Data Sheet (SDS) | βοΈ | Helps customs verify non-hazardous/non-restricted status. |
β 2. Classification Strategy (Key Rules)
π₯ βAnimal vs. Other is the Tax Dividing Line!β
| Scenario | Correct HS Code | Tax Rate | Risk |
|---|---|---|---|
| Glue Stick (Made from Gelatin) | 3506.10.10.00 |
31.5% | β οΈ High Cost. Must pay 31.5%. |
| Glue Stick (Made from PVA/Acrylic) | 3506.10.50.00 |
0.0% | β Low Cost. Best for import. |
| Large Tub (>1kg) | 3506.10.90 |
Varies | β οΈ Check for different Section 301 applicability. |
| Fish Glue | NOT 3506.10.10 | Different | β Fish glue is explicitly excluded from 3506.10.10. Misclassification here leads to fraud charges. |
β 3. Special Considerations
| Issue | Handling Advice |
|---|---|
| Blended Glues | If a glue contains both animal and synthetic components, customs may classify it as Animal Glue if animal content is dominant or determines essential character. Provide full formula. |
| Packaging | If sold in bulk (e.g., 5kg bag) but intended for retail, it may still be rejected as "Retail Pack" if the outer packaging isn't consumer-ready. Stick to β€1kg retail units for these codes. |
| Anti-Dumping | Some specific adhesives (e.g., certain PVC cements) may have separate Anti-Dumping (AD) duties. Check the specific chemical CAS numbers. |
π 5. Global Market Comparison (2026)
| Market | Recommended HS Code | Tariff (China Origin) | Notes |
|---|---|---|---|
| πΊπΈ USA | 3506.10.10.00 (Animal) / 3506.10.50.00 (Synthetic) |
31.5% (Animal) / 0% (Synthetic) | Section 301 applies heavily to Animal Glue. Synthetic is duty-free. |
| π¨π³ China | 3506.10 | 6.5% (Animal) / 0% (Other) | Import duties into China. |
| πͺπΊ EU | 3506 10 | 6.5% | Generally no punitive tariffs for adhesives. |
| π¬π§ UK | 3506 10 | 6.5% | Post-Brexit tariffs apply. |
π Conclusion: * The US market is the most critical due to the 31.5% tax on Animal Glue. * Strategy: If possible, reformulate or source synthetic-based solid glues (3506.10.50.00) to enjoy 0% duty.
π 6. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Calling all "Glue Sticks" "Animal Glue" indiscriminately.
π Consequence: Paying 31.5% when you could have paid 0% by using synthetic.
π Fix: Verify ingredients. If itβs PVA (White Glue base) or Acrylic, use 3506.10.50.00.
β Error 2: Ignoring the "1 kg" limit. π Consequence: Misclassification. Large containers might be scrutinized differently or rejected as "not retail." π Fix: Clearly declare net weight on the invoice and packaging.
β Error 3: Including Fish Glue in Animal Glue code. π Consequence: Customs may flag for fraud or misclassification, as fish glue has a different historical classification nuance. π Fix: Fish glue is explicitly excluded from 3506.10.10. Consult customs broker for specific fish glue codes.
β Error 4: Assuming "De Minimis" applies to Section 301 goods. π Consequence: Shipments under $800 from China for 3506.10.10.00 may still be subject to duty and scrutiny. π Fix: Plan for 31.5% cost even for small parcels if they are classified as 3506.10.10.00.
π― 7. Conclusion: Smart Classification, Smart Savings
π― Remember the Golden Rule:
πΉ βAnimal is Expensive (31.5%), Synthetic is Free (0%)!β
πΉ βCheck Ingredients First, Then Choose HS Code!β
β
Correct Action Plan:
1. Identify Composition: Is it animal (gelatin/casein) or synthetic (acrylic/PVA)?
2. Check Weight: Is it β€ 1 kg?
3. Select Code:
* Animal + β€1kg β 3506.10.10.00 (31.5% Tax)
* Synthetic + β€1kg β 3506.10.50.00 (0% Tax)
4. Document: Provide SDS and Ingredient Lists to prove classification.
π£ Immediate Action:
π Consult a Customs Broker: Before shipping, send your product formula to a licensed US customs broker for a Pre-Ruling (Advance Ruling). This protects you from back-taxes if the government later disputes your classification. π Optimize Supply Chain: Consider switching to synthetic formulations for the US market to save 31.5% in duties.

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
