📌 I. Product Definition and Classification: What is a "Degreaser" in Trade?

Metal Casting Degreasers are industrial chemical agents used to remove oil, grease, cutting fluids, and particulate contaminants from metal surfaces during the casting, machining, or pre-treatment processes. In international trade, their classification is highly sensitive to chemical composition. They are not a single homogeneous product but fall into different chapters based on whether they are viewed as cleaning preparations, chemical mixtures, halogenated hydrocarbons, or organic solvents.

⚠️ Critical Distinction Point:
- If the product is primarily a surfactant-based detergent for cleaning → Chapter 34
- If it is a mixed chemical product without specific surfactant focus → Chapter 38
- If it contains halogenated hydrocarbons (e.g., TCE, PCE) → Chapter 38 (Halogenated)
- If it is primarily an organic solvent mixture (e.g., mineral spirits, alcohols) → Chapter 38 (Solvents)

📦 II. HS Code Classification Details (2026 Authoritative Mapping)

Based on the provided data, here are the four primary classification paths for Metal Casting Degreasers, along with their total tax liabilities.

🔍 Key Insight:
- The lowest total tax rate is 38.7% (3824.99.55.00) or 38.8% (3402.90.10.00).
- The highest total tax rate is 41.5% (3824.99.49.00) and 41.0% (for solvent codes).
- Why the difference? It depends entirely on the Safety Data Sheet (SDS) and MSDS. If the main active ingredient is a surfactant, go Chapter 34. If it's a hydrocarbon mix, go Chapter 38. If it has halogens, go Chapter 38 (Halogenated).

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

✅ Applicable Country: USA (US)
✅ Country of Origin: China (CN)
✅ Effective Time: Post-2025 (Current Trade Environment)

🎯 1. 3402.90.10.00 – Synthetic Detergent Preparation (Surfactant-Based)

📌 Explanation:
- This is the most favorable classification if the product is truly a surfactant-based cleaner.
- Base Tariff (3.8%) is significantly lower than other options.
- The 25% Section 301 and 10% Section 122 are fixed policy burdens for Chinese-origin goods in this category.

🎯 2. 3824.99.49.00 – Prepared Chemical Products (Hydrocarbon Mix)

📌 Warning:
- This classification applies if the product is a generic hydrocarbon mixture without specific surfactant identity.
- The higher base tariff (6.5%) pushes the total cost above the detergent classification. Avoid this if you can justify the surfactant claim.

🎯 3. 3824.99.55.00 – Halogenated Hydrocarbon Mixtures

📌 Note:
- This is the absolute lowest tariff (38.7%).
- ONLY applicable if the degreaser contains halogenated hydrocarbons (e.g., Trichloroethylene, Perchloroethylene).
- Regulatory Risk: Halogenated solvents face strict environmental and health regulations (EPA, TSCA). Ensure compliance before importing.

🎯 4. 3814.00.50.10 & 3814.00.50.90 – Organic Composite Solvents

📌 Note:
- Applies if the product is primarily a liquid solvent blend (e.g., mineral spirits, alcohols) rather than a detergent or halogenated mix.
- Higher base tariff (6.0%) than detergent/halogenated options.

🛠️ IV. Customs Clearance Practical Advice (Risk Mitigation)

✅ 1. Documentation Checklist (Non-Negotiable)

✅ 2. Classification Strategy (Key to Cost Saving)

🔥 "Chemical Identity Dictates Tariff!"

📌 Pro Tip:
- If your product is 90% water + surfactants, fight for 3402.90.10.00.
- If your product is organic solvent-based, ensure the SDS emphasizes "solvent" properties, not "detergent."
- Never misrepresent halogenated content. Customs can test samples. If they find halogens but you declared non-halogenated, you face penalties.

✅ 3. Special Considerations

🌍 V. Global Market Comparison (2026 Context)

📌 Conclusion:
- The US is the most expensive market due to Section 301 (25%) and Section 122 (10%) surcharges.
- EU and China have significantly lower total duties but strict environmental/chemical regulations (REACH, etc.).
- For US imports, optimizing the HS Code to the lowest possible base tariff (3.7% or 3.8%) is critical.

📌 VI. Common Errors & Pitfalls (Learn from Others' Mistakes)

❌ Mistake 1: Declaring as "Chemical" or "Solvent" generally.
👉 Result: Customs assigns a random higher tariff code (e.g., 3824.99.99) or demands further examination → Delays & Penalties.

❌ Mistake 2: Ignoring the "Section 122" tariff.
👉 Result: Underestimating landed cost by 10%. Budget error!

❌ Mistake 3: Mislabeling Halogenated Solvents as Non-Halogenated.
👉 Result: Severe penalties from CBP and EPA. Potential criminal liability.

❌ Mistake 4: Not providing a clear SDS.
👉 Result: Customs cannot determine the chemical nature → Hold or Return.

✅ Correct Approach:

"Aqueous-based metal degreaser, containing anionic and non-ionic surfactants, surfactant content >50%, pH 9.5, Non-Flammable."
(Supports HS Code 3402.90.10.00)

🎯 VII. Conclusion: Smart Classification Saves Money

🎯 Remember This:

🔹 "SDS is King." Your Safety Data Sheet determines your HS Code.
🔹 "Surfactant = Cheaper." 3402 (3.8% base) is better than 3824 (6.5% base).
🔹 "Halogen = Cheapest but Risky." 3824.99.55 (3.7% base) is lowest but has high regulatory burden.
🔹 "Total Cost = Base + 25% + 10%." Always calculate the full 38.7-41.5% impact.

📌 Action Item:
1. Review your SDS immediately. Identify the primary active ingredient.
2. Consult a customs broker for a Pre-Ruling if you are importing large volumes.
3. Budget for 38.7-41.5% total duty if importing from China to the US.
4. Ensure EPA/DG compliance based on chemical composition.
