🧪 Chloroacetic Acid (Monochloroacetic Acid - MCAA)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Hazardous Materials Logistics Strategy
📌 1. Product Definition & Classification: What is Chloroacetic Acid?

Chloroacetic Acid is a critical intermediate chemical primarily used in the production of herbicides, dyes, pharmaceuticals, and biodegradable plastics (e.g., PGA). In international trade, it is classified under Chapter 29 (Organic Chemicals). The classification depends strictly on purity and molecular structure:

Monochloroacetic Acid (MCAA): Cl-CH₂-COOH (Single chlorine substitution).
Dichloroacetic Acid (DCAA): Cl₂-CH-COOH (Two chlorine substitutions).
Trichloroacetic Acid (TCAA): Cl₃-C-COOH (Three chlorine substitutions).

⚠️ Key Distinction Point:
- MCAA is the most common form, often sold as a melt or solid crystal. It is classified under 2915.
- Impurities/Dichloro forms may shift classification to 2915.3 or 2915.4.
- State of Matter: Liquid (Melt) vs. Solid Crystals affects packaging requirements (Hazmat Class 8) but not the HS Code itself.

📦 2. HS Code Classification Details (2026 Authoritative Alignment)

🔍 Critical Reminder:
- Most common MCAA falls under 2915.31.
- 2915.31.10.00 vs 2915.31.90.00 is often determined by purity % or crude vs. refined status as defined by local customs. Check local notes.
- Do NOT confuse with Inorganic Chlorides (Chapter 28). This is an Organic Acid.

💰 3. 2026 Latest Tariff Rate Details (Including Surtaxes & Policy Surcharge)

✅ Target Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: Post-2025 Trade Rules (301 & IEEPA)

🎯 1. 2915.31.10.00 & 2915.31.90.00 —— Monochloroacetic Acid

📌 Explanation:
- Organic acids are considered high-risk chemical intermediates.
- The 301 surcharge (25%) applies because MCAA is listed in the USITC tariff schedules for Chinese goods.
- The IEEPA 10% adds further cost.
- Total: 40.7% is a significant cost driver. Many suppliers may adjust FOB prices to offset this.

✅ 1. Required Documentation Checklist (Non-negotiable)

✅ 2. Declaration Tips (Key Mantras)

🔥 "Corrosive Class 8, UN 2928, Purity Matters, Docs Must Match!"

✅ 3. Special Handling for Corrosives

🌍 5. Global Customs Comparison (2026 Latest)

📌 Conclusion:
- USA is the most expensive market due to layered surtaxes.
- EU/India focus on REACH/Compliance rather than high tariffs.
- China is the global supply hub; importing from China means facing the 40.7% US cost.

📌 6. Common Errors & Pitfalls (Lessons Learned)

❌ Error 1: Declaring as "Inorganic Chloride" (HS 2825)
👉 Consequence: Misclassification. HS 2915 is Organic. Fines + Retrospective Tax Adjustment.

❌ Error 2: Omitting UN 2928 on Dangerous Goods Declaration
👉 Consequence: Shipment held at carrier depot. Potential return of shipment or destruction by port authority.

❌ Error 3: Inconsistent Purity in COA vs. Invoice
👉 Consequence: Customs may dispute the HS subheading (e.g., 10 vs 90). Delays.

❌ Error 4: Ignoring Solid vs. Liquid State
👉 Consequence: If liquid, flash point matters. If not declared as Flammable (Class 3), safety violation.

✅ Correct Practice:

"Monochloroacetic Acid, 99.5% Purity, Solid Crystals, UN 2928, Class 8 Corrosive, HS 2915.31.10.00"

🎯 7. Conclusion: Professional Declaration for Safe Transit

🎯 Remember the Mantra:

🔹 "2915.31 is the key, UN 2928 is the shield."
🔹 "Solid melts at 60°C, Pack right or else."
🔹 "40.7% Tax in USA, Plan your cost."

📌 Pro Tip:
If you are importing Dichloroacetic Acid (DCAA), the HS Code shifts to 2915.39.00.00, which may have different surcharge applicability. Always verify the specific chlorine count.
For USA imports, consider Section 321 De Minimis ONLY if shipped via courier under $800 and if the specific HS code is exempt (rare for Hazmat). Generally, Hazmat is NOT eligible.

📣 Immediate Action:

📞 Contact your freight forwarder for Hazmat approval BEFORE booking.
📄 Ensure MSDS Section 15 explicitly states UN Number and Proper Shipping Name.
🚀 Smooth clearance starts with precise chemical documentation!
