π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
π I. Product Definition and Classification: Do You Really Understand "Anti-Explosion Cleaning Disersant"?
An Anti-Explosion Cleaning Dispersant is a specialized chemical mixture designed for cleaning industrial equipment, machinery, or facilities in hazardous environments (e.g., oil & gas refineries, chemical plants, mining operations, aerospace manufacturing).
Key characteristics:
- Low Flammability / Non-Explosive: Formulated with non-flammable solvents (e.g., water-based, fluorinated hydrocarbons, or specialized esters) to prevent ignition in explosive atmospheres.
- Dispersion Function: Emulsifies, disperses, or dissolves grease, oil, carbon deposits, and particulate matter.
- Certifications: Typically requires certifications such as ATEX (Europe), UL Class I Div 1/2 (USA), or IECEx for use in explosive zones.
β οΈ Critical Classification Distinction:
- If the product is primarily a cleaning agent (chemical composition >70% active ingredients for cleaning) β Classified under Chapter 38 (Miscellaneous Chemical Products).
- If it is primarily a solvent (for industrial degreasing, not labeled as "cleaner") β May fall under Chapter 29 (Organic Chemicals) or Chapter 38 depending on function.
- Never classify under "Explosives" (Chapter 36) unless it is an explosive material (which it is notβit prevents explosions).

| HS Code | Product Description | Applicable Scenario | Primary Function |
|---|---|---|---|
| 3820.00.00.00 | Prepared rust preventives; prepared oils and greases for internal combustion engines or lubricating oils | Not applicable β This is for lubricants, not cleaners. | Lubrication |
| 3824.99.95.00 | Other chemical products and preparations (including those for cleaning, degreasing, etc., not elsewhere specified) | Most likely β General-purpose industrial cleaning agents with anti-static/explosion-proof formulations. | Cleaning/Degreasing |
| 3402.90.90.00 | Organic surface-active agents (including those as components or preparations), washing preparations including auxiliary washing preparations and cleaning preparations, whether or not containing soap | Possible β If the product is a surfactant-based detergent/cleaning formulation. | Cleaning/Detergent |
| 3808.94.00.00 | Insecticides, rodenticides, fungicides, herbicides, antiseptics and similar products | Not applicable β Not a pesticide or disinfectant. | Pest Control |
| 2905.16.00.00 | 2-Methyl-2-propanol (tert-Butyl alcohol) | Not applicable β Only if the product is pure solvent, not a mixture. | Solvent |
| 3824.60.00.00 | Halogenated (including fluorinated) organic products | Possible β If based on fluorinated solvents (e.g., HFCs, PFCs) for precision cleaning. | Solvent/Cleaner |
π Key Reminder:
- Most "Anti-Explosion Cleaning Dispersants" fall under3824.99.95.00or3402.90.90.00, depending on whether they are surfactant-based (3402) or chemical mixtures (3824).
- Do NOT classify under Chapter 36 (Explosives) β This is a preventive agent, not an explosive.
- Do NOT classify under Chapter 29 unless it is a pure organic chemical (unlikely for a commercial cleaning product).

π οΈ IV. Customs Clearance Practical Suggestions (Battle-Tested Pitfall Avoidance Guide)
β 1. Required Documentation Checklist (None Can Be Omitted)
| Document | Required | Description |
|---|---|---|
| β Product Safety Data Sheet (SDS/MSDS) | βοΈ | Must comply with GHS (Globally Harmonized System) and highlight flammability class (e.g., Class 9 or non-flammable). |
| β Certificate of Analysis (COA) | βοΈ | Confirms chemical composition, active ingredients, and absence of hazardous/explosive properties. |
| β Certification for Explosive Atmospheres | βοΈ | ATEX, UL Class I Div 1/2, or IECEx certificates proving the product is safe for use in explosive zones. |
| β Commercial Invoice | βοΈ | Clearly state: "Anti-Explosion Cleaning Dispersant, Non-Flammable, For Industrial Degreasing" |
| β Packing List | βοΈ | Detail net/gross weight, number of containers, and hazard class (if any). |
| β FDA/ EPA Registration (If Applicable) | βοΈ | If used in food-grade environments, EPA registration may be required. |
β 2. Declaration Strategy (Key Mantra)
π₯ "Declare by Function, Not by Name; Highlight Non-Flammability; Avoid 'Explosive' Misclassification!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Industrial cleaner for hazardous zones | 3824.99.95.00 - "Chemical Cleaning Preparation, Non-Flammable" |
Calling it "Explosive Cleaner" β Triggers Chapter 36 investigation |
| Solvent-based degreaser | 3824.60.00.00 - "Halogenated Cleaning Agent" |
Mislabeling as "Lubricant" β Wrong HS Code, penalties |
| Water-based anti-static cleaner | 3402.90.90.00 - "Surfactant Cleaning Preparation" |
Under-declaring as "Water" β Fraud risk |
| Bulk chemical shipment | 3824.99.95.00 |
Mixing with flammable solvents in same container β Safety violation |
β 3. Special Handling Cases
| Case | Handling Suggestion |
|---|---|
| UN Number Assignment | If non-flammable, may be UN3082 (Environmentally Hazardous Substance, Solid) or UN3077 (Environmentally Hazardous Substance, Liquid). If truly non-hazardous, no UN number. |
| Flammability Labeling | Must display GHS Label with "Non-Flammable" or "Low Flammability" symbol. |
| Food-Grade vs. Industrial | If food-grade, EPA/FDA documentation is mandatory; otherwise, industrial use only. |
| Ocean Freight Hazmat Declaration | If classified as Class 9 (Miscellaneous Dangerous Goods), must file DGD (Dangerous Goods Declaration) with carrier. |
π V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification Requirements | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 3824.99.95.00 or 3402.90.90.00 |

π VI. Common Mistakes & Pitfall Avoidance Guide (Lessons from Blood)
β Mistake 1: Classifying under Chapter 36 (Explosives) because of the word "Explosion" in the name
π Consequence: 100% inspection, seizure, or fines!
π Solution: Emphasize "Prevention" and "Non-Flammable" in declaration.
β Mistake 2: Omitting SDS/MSDS or providing outdated GHS version
π Consequence: Delay at customs, return of shipment
π Solution: Update SDS to latest GHS Rev. 9 (2025) standard.
β Mistake 3: Mislabeling flammable solvents as "Non-Explosive"
π Consequence: Safety violation, criminal liability
π Solution: Accurate flammability classification based on flash point testing.
β Mistake 4: Ignoring REACH (EU) or TSCA (US) chemical registration requirements
π Consequence: Import blocked, fines up to $50,000/day
π Solution: Verify chemical substances are registered under respective regulations.
β Correct Declaration Example:
"Anti-Explosion Industrial Cleaning Dispersant, Water-Based, Non-Flammable, For Use in Hazardous Zones, SDS Provided, HS Code 3824.99.95.00"
π― VII. Conclusion: Professional Declaration, Save Time and Cost!
π― Remember Mantra:
πΉ "Non-Flammable is Key, SDS is Mandatory, Avoid Chapter 36, Declare as Chemical Cleaner!"
πΉ "HS Code determines duty, Tariff varies by composition, Declaration accuracy saves thousands!"
π Pro Tip:
If your cleaning dispersant contains fluorinated compounds (e.g., PFAS), it may be subject to additional environmental regulations in the EU, US, and Australia. Test for PFAS content and declare accurately.
π£ Immediate Action:
π Contact a licensed customs broker + Provide SDS + Verify IEEPA Applicability
π Ensure smooth clearance, avoid delays, and maximize efficiency!
β¨ Professional Clearance Starts with Accurate Classification!

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
