Alkylbenzene Degreaser

🧪 Alkylbenzene Degreaser / Desulfurization Agents

(Chemical Products & Preparations for Industrial Application)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What Exactly Is This Chemical?

Alkylbenzene Degreaser and related Desulfurization/De-greasing Agents are complex chemical mixtures used primarily in industrial cleaning, metal processing, and chemical synthesis. They fall under Chapter 38 (Miscellaneous Chemical Products) due to their nature as prepared substances rather than pure single-compound chemicals.

Depending on the specific formulation, primary function (degreasing vs. desulfurization), and chemical base (alkylbenzene vs. alkyl naphthalene), these products are classified into distinct HS Codes with varying tariff implications.

⚠️ Key Distinction Point:
- If the product is primarily an Alkylbenzene-based agent for Desulfurization → It is treated as a specific chemical preparation.
- If the product is a Mixed Alkyl Naphthalene agent for Degreasing → It is classified under "Other Chemical Products" or "Naphthenic/Naphthalene components."
- Critical Note: The specific HS code depends on whether the customs authority views the item as a "General Chemical Mixture" or a "Specific Functional Agent."

📦 II. HS Code Classification Details (2026 Latest Tariff Reference)

Based on the provided data, there are 4 unique HS Code scenarios for this product type, all originating from China (CN) and importing into the US (US).

🔍 Important Observation:
- Two different HS codes share the description "Alkylbenzene Desulfurization Agent" (...86 and ...97) but have different final digits, possibly reflecting minor procedural or sub-category differences in US Customs databases.
- "Degreaser" variants are split between Alkyl Naphthalene bases (...75.10 and ...97).
- All listed codes carry high additional tariffs due to US-China trade tensions.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: Current enforcement (Section 301 & IEEPA)

🎯 1. 3824.99.93.86 —— Alkylbenzene Desulfurization Agent

📌 Explanation:
- The 5% is the standard Most Favored Nation (MFN) duty for "Other Prepared Chemicals."
- The 25% is the Section 301 tariff targeting Chinese industrial chemicals.
- The 10% is a specific "122 Clause" surcharge, likely related to specific chemical safety or trade remediation measures.
- Total 40% significantly impacts cost structures.

🎯 2. 3824.99.93.97 —— Alkylbenzene Desulfurization Agent (Other Use) / Mixed Alkyl Naphthalene Degreaser

📌 Note:
- Despite potentially different sub-descriptions ("Other chemical products" vs "Industrial mixture"), the tariff structure is identical to ...86.
- This applies to both Alkylbenzene and Mixed Alkyl Naphthalene degreasers classified under this "Other" bucket.

🎯 3. 3824.99.75.10 —— Mixed Alkyl Naphthalene Degreaser (Specific Naphthalene Use)

📌 Key Difference:
- This code has a lower basic tariff (3.7%) compared to the others (5.0%), resulting in a slightly lower total rate (38.7% vs 40.0%).
- It specifically targets "Naphthenic acids and related chemical components," suggesting a more specific chemical definition.
- Savings: 1.3% difference on CIF value.

🛠️ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)

✅ 1. Required Documentation Checklist

✅ 2. Declaration Tips (Crucial Keywords)

🔥 Rule of Thumb: "Be Specific, Be Accurate, Avoid General Terms!"

📌 Warning:
- Do NOT use generic terms like "Cleaning Fluid" or "Solvent" without specifying the chemical base (Alkylbenzene/Naphthalene).
- Customs may reclassify under higher-duty "Hazardous Waste" or "General Chemicals" if description is vague.

✅ 3. Special Handling Cases

🌍 V. Global Market Comparison (2026 Update)

📌 Conclusion:
- USA is the most expensive market due to the 35-40% total tariff burden.
- EU and Japan are more cost-effective but require strict chemical registration (REACH in EU).
- Profit Margin Alert: With 40% tariffs, only high-value, high-margin industrial chemicals can absorb these costs.

📌 VI. Common Mistakes & Pitfall Guide (Lessons Learned)

❌ Mistake 1: Declaring "Alkylbenzene" as "General Solvent"
👉 Consequence: Misclassification → 20% penalty + back taxes

❌ Mistake 2: Ignoring the "122 Clause"
👉 Consequence: Under-declaration by 10% → Seizure or heavy fines

❌ Mistake 3: Combining Alkylbenzene and Naphthalene in one line item
👉 Consequence: Customs may apply the higher rate (40%) to the entire shipment instead of splitting them

❌ Mistake 4: Claiming "De Minimis" Exemption
👉 Consequence: Rejected → Full duty collection + storage fees

✅ Correct Practice:

"Alkylbenzene Desulfurization Agent, CAS No. [Insert], Chemical Preparation, HS 3824.99.93.86, CIF Value: $10,000"

🎯 VII. Conclusion: Professional Compliance Saves Money

🎯 Remember the Tariff Formula:

🔹 Base Duty (3.7-5%) + Section 301 (25%) + 122 Clause (10%) = 38.7% - 40%
🔹 Total Tax Rate is FIXED for China-Origin Chemicals in USA
🔹 HS Code Choice Only Affects Base Duty (1.3% Difference!)

📌 Pro Tip:

• If your product contains >50% Alkyl Naphthalene, try to qualify for 3824.99.75.10 to save 1.3% on the CIF value.
• For Alkylbenzene, the rate is fixed at 40%.
• Pre-clearance with a licensed customs broker is highly recommended to confirm the exact sub-heading before shipment.
