AI Analysis
🧪 Glue & Desiccant 4-in-1 (Composite Adhesive Kits)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "4-in-1 Glue"?
"4-in-1 Glue with Desiccant" typically refers to a composite kit containing various types of adhesives (often including super glue, primer, and perhaps tools or desiccants for moisture control) packaged together. In international trade, the classification hinges on whether the item is considered a "prepared adhesive" or a "mixed set" where the essential character is the adhesive.
Key Classification Logic: 1. Material Attribute: The term "Glue" (胶/胶水) directly aligns with "Prepared Adhesives" under Chapter 35. 2. Composite Nature: The "4-in-1" description implies a compounded or prepared form, fitting the category of "other prepared adhesives." 3. Desiccant Role: If the desiccant is minor and essential for the glue's performance (preventing curing), it does not change the primary classification of the glue. If it's a separate, major component, it might complicate things, but海关 (Customs) often defaults to the main functional item (the adhesive).
⚠️ Critical Distinction:
- If sold as a single unit where the glue is the primary value/function → Classified under 3506.
- If sold as separate retail packages not packed together → Might be split classified, but "4-in-1" implies a kit.
- Deduction Principle: In the absence of specific polymer details, "Other" subheadings are used as the catch-all.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, there are two primary HS Code candidates. Both carry the same high tariff burden due to trade policies.
| HS Code | Product Description | Applicability Logic | Key Characteristic |
|---|---|---|---|
3506.99.00.00 |
Other prepared adhesives (Main Recommendation) | The term "Glue" fits "Prepared Adhesive." "4-in-1" indicates a compounded form. Matches "Other Prepared Adhesives." | ✅ Best Fit: Explicitly mentions "Prepared Adhesives" and "Compounded Form." |
3506.91.50.00 |
Other adhesives (Based on "Glue" inference) | Inferred as adhesive material under 3506. Since specific polymer/weight isn't stated, "Other" is used as a fallback. | ⚠️ Fallback: Used if specific polymer type is unknown, but less precise than 3506.99 for kits. |
🔍 Important Note:
- Both codes result in the same total tax rate due to current trade policies.
- The description "4-in-1" (四合一) strongly supports 3506.99.00.00 because it describes a composite/prepared product, not just a raw chemical.
- The presence of Desiccant does not shift the code to Chapter 38 (Chemical Products) if the desiccant is merely accessory to the glue's storage.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Time: 2025/2026 (Current Trade Policy)
🎯 1. 3506.99.00.00 —— Other Prepared Adhesives (Recommended)
| Item | Detail |
|---|---|
| Base Tariff | 2.1% (Ad valorem) |
| Section 301 Surcharge | +25.0% (Added tariff for Chinese goods) |
| 122 Clause Surcharge | +10.0% (Specific provision for certain chemicals/adhesives) |
| Total Tax Rate | 37.1% |
| Tax Calculation | CIF Value × 37.1% |
| De Minimis Exemption | ❌ Not Eligible (High-risk category for low-value shipments) |
| Legal Basis Path | USITC:3506.99.00.00 → Section 301: Footnote 9903.88.01 → 122 Clause Provision |
📌 Explanation:
- Base 2.1%: Standard Most Favored Nation (MFN) rate for prepared adhesives.
- 25% Surcharge: Part of the Section 301 trade war tariffs affecting Chinese goods.
- 10% Surcharge: Specific "122 Clause" tariff, often applied to certain chemical preparations or adhesives to protect domestic manufacturing.
- Total 37.1%: This is a significant cost. Importers must factor this into pricing.
🎯 2. 3506.91.50.00 —— Other Adhesives (Alternative)
| Item | Detail |
|---|---|
| Base Tariff | 2.1% |
| Section 301 Surcharge | +25.0% |
| 122 Clause Surcharge | +10.0% |
| Total Tax Rate | 37.1% |
| Tax Calculation | CIF Value × 37.1% |
| De Minimis Exemption | ❌ Not Eligible |
📌 Note:
- The tax rate is identical.
-3506.99.00.00is preferred because "4-in-1" implies a preparation/mixing process, which fits "Prepared Adhesives" (3506.99) better than generic "Other Adhesives" (3506.91).
🛠️ IV. Customs Clearance Practical Advice (Avoiding Pitfalls)
✅ 1. Required Documentation Checklist
| Document | Mandatory? | Purpose |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must list ingredients, weight of glue vs. desiccant, and "4-in-1" composition. |
| ✅ Commercial Invoice | ✔️ | Clearly state "Glue Kit" or "Prepared Adhesives." Avoid vague terms like "Household Supplies." |
| ✅ Packing List | ✔️ | Show that items are packed together as a single retail unit. |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Crucial for adhesives. Must confirm flammability, chemical composition, and desiccant type. |
| ✅ Brand Authorization | ✔️ | If branded, to avoid IP issues. |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 "Glue is Prepared, Kit is Combined, Name it Right, Avoid Delight!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| "4-in-1 Glue Kit" | 3506.99.00.00 - "Prepared Adhesives, 4-in-1 Kit" |
Calling it "Cleaning Supplies" → Risk of misclassification. |
| Glue + Separate Desiccant Packet | Still 3506.99.00.00 |
If desiccant is large, might need Chapter 38 → Higher complexity. |
| Bulk Glue (No Kit) | 3506.91.50.00 or 3506.99.00.00 |
Don't use kit terminology. |
✅ 3. Special Handling Notes
| Situation | Handling Advice |
|---|---|
| Desiccant Content | If desiccant is >10% by weight, customs may question if it's a "chemical preparation." Keep it minimal and clearly labeled as "Moisture Absorber for Glue." |
| Flammability | Many adhesives are flammable. Ensure UN38.3 testing if shipped by air. Misdeclaration can lead to severe fines. |
| Labeling | Must include English safety warnings, ingredient list, and country of origin (China). |

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
