π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: What Exactly is "Inorganic Anti-Wear Agent"?
An Anti-Wear Agent is a chemical additive used in lubricants (oil/grease) to reduce friction and prevent metal-to-metal contact under heavy loads.
When the specification explicitly states "Inorganic" (ζ ζΊ), it implies the active ingredients are inorganic salts (such as carbonates, borates, phosphates, or zinc salts) rather than organic compounds (like ZDDP). This distinction is critical for HS Code classification because Organic additives often fall under Chapter 29 (Organic Chemicals) or 38.11 (Preparations for Lubricants), while Inorganic additives may fall under Chapter 28 (Inorganic Chemicals) or Chapter 38 (Miscellaneous Chemical Products) depending on their formulation.
β οΈ Key Classification Distinction:
- Pure Inorganic Salts (Single Substance): Likely classified under Chapter 28 (e.g., Carbonates, Borates).
- Mixture of Inorganic Compounds (Preparation): Likely classified under Chapter 38.24 (Prepared Binders for Foundry Molds... or Other Chemical Products).
- Lubricant Additive Preparation: If mixed with organic bases or sold as a ready-to-use additive package, it often falls under 38.24.99 regardless of being inorganic, due to the "preparation" nature.
π¦ II. HS Code Classification Details (2026 Latest Tariff Alignment)
Based on the provided data, there are five potential HS Code classifications depending on the specific chemical composition and regulatory interpretation of "Inorganic Anti-Wear Agent."
| HS Code | Product Description | Basis for Classification | Total Tax Rate |
|---|---|---|---|

Inorganic Salts (Carbonates/Borates) | Classified as "Other" inorganic salts (carbonates/borates). Fits the "Inorganic" material requirement. | +10.0% |
2842.90.90.10 |
Other Inorganic Salts (Acid/Peracid Salts) | Classified as "Other salts of inorganic acids." Fits the "Inorganic" chemical attribute. | +10.0% |
3824.99.39.90 |
Prepared Chemical Product (Mixture) | Classified as a "Mixture of two or more inorganic compounds." Considered a "Preparation" in Chapter 38. | 35.0% |
3824.99.31.00 |
Prepared Chemical Product (Specific) | Classified as a "Mixture of inorganic compounds" + Anti-wear agent. Specific subheading for preparations. | 41.5% |
2836.99.30.00 |
Carbonate-Based Anti-Wear Agent | Classified as "Other" carbonates. "Anti-wear" is seen as a function, "Inorganic" fits carbonate properties. | 36.7% |
π Critical Insight:
- Chapter 28 Codes (2836...,2842...) apply if the product is a single substance or a simple mixture of inorganic salts without complex organic binders.
- Chapter 38 Codes (3824...) apply if the product is a preparation (mixed with other substances, solvents, or stabilizers) or a complex mixture of inorganic compounds intended for industrial use.
- Tax Disparity: The tax rate ranges from 10% (simple salts) to 41.5% (complex preparations). Misclassification can lead to significant duty differences.

π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Essential Documentation Checklist
| Document | Required? | Purpose |
|---|---|---|
| β Certificate of Analysis (CoA) | YES | Must explicitly state the chemical composition. Prove if it is a single inorganic salt (Ch 28) or a mixture/preparation (Ch 38). |
| β Technical Data Sheet (TDS) | YES | Show that it is an "Anti-Wear Agent" and list all ingredients. |
| β Formula/Composition List | YES | Critical for distinguishing between Chapter 28 (Pure) and Chapter 38 (Mixture). |
| β Commercial Invoice | YES | Must describe the product accurately: "Inorganic Anti-Wear Agent, [Chemical Name], HS Code XXXX." |
| β Original & Clean Copy | YES | To prove origin and avoid delays. |
β 2. Declaration Strategy (Key Rules)
π₯ "Material Defines Code, Preparation Defines Tax!"
| Situation | Recommended HS Code | Risk if Misclassified |
|---|---|---|
| Pure Zinc Phosphate / Borates (No other additives) | 2836.99.50.50 or 2842.90.90.10 |
Declaring as Ch 38 β Overpay 25-31% in duties. |
| Mixture with Organic Binders/Solvents | 3824.99.39.90 or 3824.99.31.00 |
Declaring as Ch 28 β Customs Audit, Penalties, Back Taxes. |
| Carbonate-based Anti-wear | 2836.99.30.00 |
Declaring as 3824... β Overpay 5-8%. |
| Generic "Lubricant Additive" | UNCLEAR | HIGH RISK. Must provide CoA to determine if Organic (Ch 29/38.11) or Inorganic (Ch 28/38). |
β 3. Special Handling Tips
| Scenario | Action |
|---|---|
| Product is a Powder/Paste | Ensure CoA confirms it is not a "preparation" containing organic solvents. If it's dry powder of pure salts, fight for Chapter 28. |
| Product is a Liquid Solution | Likely a Preparation. Prepare for Chapter 38 tariffs (35-41.5%). |
| Name Ambiguity | Do NOT just write "Anti-Wear Agent." Use "Inorganic Anti-Wear Agent, Zinc Borate, [Grade]" to trigger Ch 28 consideration. |
| Origin China | Always factor in the 10% IEEPA tariff. Even Ch 28 codes are not tax-free for China-origin goods. |

π VI. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Assuming all "Lubricant Additives" are Chapter 38.
π Reality: If the active ingredient is a pure inorganic salt, it may belong in Chapter 28.
π Impact: Save 25-31% in duties.
β Mistake 2: Ignoring the IEEPA 10% surcharge for Chapter 28 goods.
π Reality: Even with 0% base duty, China-origin goods pay +10%.
π Impact: Underestimating landed cost by 10%.
β Mistake 3: Using generic names like "Anti-Wear Powder" without a CoA.
π Reality: Customs will likely classify under 3824.99.31.00 (highest tax) due to lack of proof of pure salt status.
π Impact: 41.5% Tax instead of 10%.
β Mistake 4: Confusing "Organic" (ZDDP) with "Inorganic" (Zinc Phosphate/Borates).
π Reality: Organic anti-wear agents are often Chapter 29 or 38.11, with different tax structures.
π Impact: Wrong HS Code β Customs Hold.
β Best Practice:
"Provide a Certificate of Analysis (CoA) specifying 'Inorganic Salts Only'. Declare as Chapter 28 to leverage 10% IEEPA-only rate."
π― VII. Conclusion: Maximize Profit via Precise Classification
π― Key Takeaway:
πΉ "Inorganic is Key."
πΉ "Pure Salt = Chapter 28 (10% Total)."
πΉ "Mixture/Prep = Chapter 38 (35-41.5% Total)."

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
