🧪 Raw Materials in Cubic Centimeters (cm³)

🌐 HS Code & Tariff Guide | 2026 Customs Classification & Duty Breakdown | Professional Import Strategy
📌 One, Product Definition & Classification: What Are You Really Importing?

Raw materials in cubic centimeters (cm³) refer to liquid or semi-liquid chemical substances measured by volume, commonly used in industrial applications such as:

• Foundry binders (for molds and cores)
• Chemical mixtures (especially acyclic, monohydric, unsubstituted alcohols)
• Industrial adhesives, coatings, and specialty formulations

⚠️ Key Distinction:
- If the material is a liquid mixture used in foundry processes or chemical manufacturing → HS Code 3824.99.93.97 or 3824.99.93.30
- If it's a solid, powder, or non-measurable form, it may fall under different HS codes (e.g., 3811, 3912)
- Volume (cm³) is NOT the primary classification factor — chemical composition and intended use are.

📦 Two, HS Code Classification Details (2026 Official Tariff Reference)

🔍 Critical Insight:
- Both codes are volume-measured in cubic centimeters (cm³) — this is standard for liquid chemicals in customs declarations.
- The exact chemical composition must be declared to avoid misclassification.
- "Other" in both codes means: not specifically listed elsewhere in the tariff schedule, so full technical data is required.

💰 Three, 2026 Latest Tariff Breakdown (With附加 Taxes Explained)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (with ongoing enforcement)

🎯 1. 3824.99.93.97 — Prepared Binders for Foundry Molds/Cores (Other)

📌 Explanation:
- 5% base tariff applies to all chemical preparations under this subheading.
- +25% USITC tariff is from Section 301 of the U.S. Trade Act — targeting Chinese-origin chemicals deemed to have unfair trade practices.
- No IEEPA 10% added here (only applies to specific categories like electronics, textiles, etc.).
- Total: 30% — high but not the highest in the chemical category.

🎯 2. 3824.99.93.30 — Mixtures of Acyclic, Monohydric, Unsubstituted Alcohols (Other)

📌 Important Note:
- This includes ethanol, propanol, butanol mixtures, and similar pure alcohol-based formulations.
- Even if labeled as "solvent" or "chemical blend", if it's acyclic, monohydric, unsubstituted, it falls under this code.
- No distinction between industrial vs. lab use — all are subject to 30% duty.

🌍 Five, Global Market Comparison (2026 Update)

📌 Key Takeaway:
- The U.S. is the only market imposing 30% duty on these chemical liquids from China.
- Vietnam, Mexico, and Thailand can avoid this via trade agreements.

📌 Six, Common Mistakes & How to Avoid Them (Real-World Pitfalls)

❌ Mistake 1: Declaring "chemical" without specifying HS Code 3824.99.93.97 or 3824.99.93.30
👉 Result: Customs delays, classification audit, potential seizure

❌ Mistake 2: Failing to declare volume in cm³ on invoice or packing list
👉 Result: Rejection — volume is mandatory for liquid chemicals

❌ Mistake 3: Using generic name like "industrial binder" without chemical details
👉 Result: Misclassification → 30% duty applied incorrectly

❌ Mistake 4: Not providing CAS number or chemical structure
👉 Result: Request for additional info → 2–4 week delay

✅ Correct Declaration Example:

"Prepared binder for foundry cores, 3824.99.93.97, 5000 cm³, CAS 12345-67-8, non-hazardous, SDS attached"

🎯 Seven, Conclusion: Precision in Classification = Profit Protection

🎯 Remember the Rule of 30%:

🔹 30% duty applies to all Chinese-origin chemical liquids in these two HS codes
🔹 No de minimis exemption — even 1 cm³ is taxed
🔹 Volume (cm³) is key — declare it clearly on every document

🔹 "Volume is the measure, composition is the key, origin is the cost!"

📌 Pro Tip:
If your raw material is from Vietnam, Mexico, or Thailand, apply for USMCA or RCEP certification → 0% duty on these HS codes.
