Linolenic Acid

🧪 Linolenic Acid (亚麻酸) & Fatty Acid Alcohols

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

"Linolenic Acid" is a broad term that often leads to classification errors because it can refer to two chemically distinct categories: Essential Fatty Acids (Chemicals) and Industrial Single Carboxylic Acids (Mixtures). The key to accurate HS Code classification lies in the purity, chemical structure, and intended use.

⚠️ Critical Distinction:
- If the product is pure chemical Linolenic Acid (C18:3) intended for pharmaceutical, food, or fine chemical use → It falls under Chapter 29 (Organic Chemicals).
- If the product is a mixture or derivative (e.g., industrial-grade fatty acid mixtures containing linolenic acid) → It may fall under Chapter 38 (Miscellaneous Chemical Products).
- If the product is Linolenic Alcohol (the reduced alcohol form) → It is classified as an Alcohol under Chapter 29 or a Chemical Mixture under Chapter 38 depending on substitution status.

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

🔍 Key Alert:
- Chemical vs. Mixture: If your product is pure Linolenic Acid, use 2916.15.xxxx. Do NOT use 3823 unless it is explicitly an industrial mixture.
- Alcohol Derivative: If you are importing Linolenic Alcohol (reduced form), it is not Linolenic Acid. Use 3824.99.93.10 for mixtures or check specific alcohol codes if pure.
- Tax Variance: The difference between 2916.15.51.00 (39.4%) and 2916.15.10.00 (41.5%) depends on specific subheading interpretations. Consistency in chemical naming is critical.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes & Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (inclusive of subsequent imports)

🎯 1. 3823.19.40.00 – Industrial Single Carboxylic Acids

📌 Explanation:
- This code is used when Linolenic Acid is classified as an industrial single carboxylic acid.
- The 7.5% Section 301 surcharge applies to most chemical imports from China.
- The 10% Section 122 tariff is a specific add-on for certain chemical products.
- Total 20.7% is significantly lower than the pure chemical codes, BUT only if your product truly qualifies as "Industrial Single Carboxylic Acid" (not pure pharmaceutical/food-grade Linolenic Acid).

🎯 2. 2916.15.51.00 – Other Unsaturated Acids (Linolenic Acid)

📌 Explanation:
- This code is for pure Linolenic Acid where the material name matches the classification exactly.
- The 25% Section 301 surcharge is the highest tier, applying to most organic chemicals.
- The 10% Section 122 tariff is also applied.
- Total 39.4% is high. Ensure your product is not misclassified here if it can legally qualify as an industrial mixture (20.7%).

🎯 3. 2916.15.10.00 – Other Unsaturated Acids (Linolenic Acid)

📌 Explanation:
- Similar to 2916.15.51.00, but with a higher base rate (6.5% vs 4.4%).
- Total 41.5% is the highest among Linolenic Acid classifications.
- Use this only if your product strictly matches the subheading explanation for "Other Unsaturated Acids" under this specific code. Avoid if possible due to higher cost.

🎯 4. 3824.99.93.10 – Linolenic Alcohol (Chemical Mixture)

📌 Explanation:
- This code applies to Linolenic Alcohol (not Linolenic Acid), classified as a chemical mixture.
- It fits the "catch-all" principle for non-cyclic, mono-hydroxy, unsubstituted alcohols.
- Total 40.0% is high. Ensure you are importing the alcohol, not the acid. If you import "Linolenic Acid" but declare it as "Alcohol," it will be seized and penalized.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)

✅ 1. Documentation Checklist (Mandatory)

✅ 2. Declaration Tips (Key Mantra)

🔥 "Acid vs. Alcohol, Purity is Key! Industrial vs. Pure, Choose Wisely!"

✅ 3. Special Case Handling

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- USA has the highest tariff burden due to Section 301 and Section 122 surcharges.
- EU and Australia offer significantly lower tariffs for the same product.
- Classify correctly: Misclassifying pure Linolenic Acid as industrial can lead to heavy fines for fraud.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring Linolenic Alcohol as Linolenic Acid
👉 Consequence: Seizure, fine, and potential legal action.
✅ Fix: Use exact chemical names. Alcohol ≠ Acid.

❌ Mistake 2: Using 3823.19.40.00 for Pure Linolenic Acid to save tax
👉 Consequence: Customs will reject, demand reclassification, and issue penalties.
✅ Fix: Only use 3823 for industrial mixtures. Pure acid goes to 2916.

❌ Mistake 3: Vague description "Fatty Acid"
👉 Consequence: Customs will guess the code, likely applying the highest rate or holding shipment.
✅ Fix: Use CAS Number and IUPAC Name.

🎯 VII. Conclusion: Professional Declaration Saves Money!

🎯 Remember Mantra:

🔹 "Pure Acid = 2916 (39-41%) / Industrial Mixture = 3823 (20.7%)"
🔹 "Alcohol ≠ Acid. Check the functional group!"
🔹 "CAS Number is your best friend for chemical clearance."

📌 Pro Tip:
If your Linolenic Acid is originally from Vietnam, Mexico, Thailand, or Malaysia, you may qualify for IEEPA exemptions or reduced tariffs.
