🧪 Oleic Acid Deacidification and Purification Product
🌐 HS Code Classification & Customs Clearance Guide | 2026 Updated Tariff Analysis | Professional Import Strategy
📌 One, Product Definition & Classification: What Exactly Is "Oleic Acid Deacidification and Purification Product"?
Oleic acid is a monounsaturated fatty acid widely used in cosmetics, pharmaceuticals, lubricants, and industrial chemicals. The "deacidification and purification product" refers to high-purity oleic acid obtained through distillation, chemical refining, or physical purification of crude plant or microbial oils (e.g., from olive oil, sunflower oil, or microbial fermentation).
⚠️ Key Distinction:
- If the product is pure oleic acid after chemical modification or fractional distillation, it is not a crude oil — it is a refined fatty acid derivative.
- It must be classified under fatty acid or purified oil fractions, not under raw oils or fats.
📦 Two, HS Code Classification Details (2026 Latest Tariff Authority Match)
| HS Code | Product Description | Applicable Scenario | Classification Basis |
|---|---|---|---|
1515.90.81.90 |
Purified oleic acid, a distillation product of fixed vegetable or microbial oils (refined/purified), meets the definition of "other oils and fats, not elsewhere specified" | High-purity oleic acid from natural sources, chemically refined or distilled | ✅ Matches: 1515.90.81.90 – "Purified oleic acid" |
1518.00.40.00 |
Oleic acid, purified or chemically modified, falls under "fatty acids, whether or not chemically modified" | Oleic acid with purification or minor chemical treatment (e.g., esterification) | ✅ Matches: 1518.00.40.00 – "Fatty acids, not elsewhere specified" |
1515.90.21.00 |
Oleic acid, purified form, classified as "refined or fractionated fixed vegetable or microbial oils" | Oleic acid derived from fractionation of natural oils, not chemically altered | ✅ Matches: 1515.90.21.00 – "Purified oils, fractionated" |
1518.00.20.00 |
Oleic acid, purified, as "other fatty acids" with a per-kilogram duty | Oleic acid in bulk form, with specific duty rate per kg | ✅ Matches: 1518.00.20.00 – "Fatty acids, with specific duty" |
🔍 Critical Insight:
- All four HS codes apply depending on the purification process and chemical state.
- No single code fits all cases — the exact manufacturing process determines the correct classification.
💰 Three, 2026 Latest Tariff Breakdown (With Full Duty Clause Explanation)
✅ Applicable Country: United States (US)
✅ Origin: China (CN), or other countries under U.S. trade policy
✅ Effective Date: November 10, 2025 (and onward)
🎯 1. 1515.90.81.90 — Purified Oleic Acid (Distillation Product)
| Item | Detail |
|---|---|
| Base Duty | 3.2% (ad valorem) |
| Additional Duty (Section 301) | +7.5% (from USITC, under Section 301 of Trade Act) |
| IEEPA Duty (Section 122) | +10% (under International Emergency Economic Powers Act) |
| Total Effective Duty | 20.7% |
| Duty Calculation | CIF Value × 20.7% |
| De Minimis Exemption? | ❌ No (denied under U.S. de minimis rule for China-origin goods) |
| Legal Basis Path | IEEPA:9903.01.25 → Section 122:9903.01.24 → USITC:1515.90.81.90 → FOOTNOTE:9903.88.01 |
📌 Explanation:
- This code applies to oleic acid purified via distillation or physical refining of plant oils.
- The 10% IEEPA duty is triggered by China-origin goods under national security concerns.
- No de minimis relief — even small shipments face full duty.
🎯 2. 1518.00.40.00 — Oleic Acid (Chemically Modified or Purified)
| Item | Detail |
|---|---|
| Base Duty | 8.0% (ad valorem) |

📌 Explanation:
- Applies when the product is sold by weight (e.g., bulk liquid oleic acid).
- Dual duty structure: specific + ad valorem → higher cost for large-volume shipments.
🛠️ Four, Customs Clearance Best Practices (Pro Tips to Avoid Penalties)
✅ 1. Required Documentation (Must-Have List)
| Document | Required? | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Include purity (≥98%), source (e.g., olive, sunflower), process (distillation/refining) |
| ✅ Certificate of Analysis (COA) | ✔️ | Prove oleic acid content, free fatty acid level, moisture |
| ✅ Process Flow Diagram | ✔️ | Show if chemical modification occurred (critical for code choice) |
| ✅ Commercial Invoice | ✔️ | Clearly state: "Purified Oleic Acid, 98%+ purity, from vegetable oil distillation" |
| ✅ Origin Certificate (CO) | ✔️ | If from non-China origin (e.g., EU, Brazil), may qualify for lower duty |
| ✅ Packing List | ✔️ | Show net weight, container ID, batch number |
| ✅ MSDS / Safety Data Sheet | ✔️ | Required for chemical imports |
✅ 2.申报技巧 (申报口诀)
🔥 “Process Defines Code, Purity Matters, China Origin = 17.5%+!”
| Scenario | Correct HS Code | Wrong Approach |
|---|---|---|
| Oleic acid from distillation only, no chemical change | 1515.90.21.00 |
Misclassified as 1518.00.40.00 → higher duty |
| Oleic acid chemically modified (e.g., esterified) | 1518.00.40.00 |
Misclassified as 1515.90.81.90 → risk of audit |
| Bulk liquid, sold by kg | 1518.00.20.00 |
Misclassified as ad valorem → underpaid duty |
| High-purity (>98%) from natural source | 1515.90.81.90 |
Misclassified as 1518.00.40.00 → overpay |
✅ 3. Special Cases & Risk Mitigation
| Case | Recommendation |
|---|---|
| Oleic acid from non-China origin | Apply for IEEPA exemption → duty drops to 0%–5% |
| Oleic acid used in pharmaceuticals | Apply for "medical use" exemption (requires FDA documentation) |
| Oleic acid for industrial lubricants | May qualify for "non-commercial" use — requires pre-approval |
| Oleic acid from microbial fermentation | Still falls under 1515.90.81.90 or 1518.00.40.00 — no special code |
🌍 Five, Global Customs Comparison (2026)
| Country | Recommended HS Code | Base Duty | Additional Duties | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 1515.90.21.00 or 1518.00.40.00 |
0%–8% | +7.5% +10% | Total: 17.5%–25.5% |
| 🇨🇳 China | 1515.90.81.90 |
5% | None | No IEEPA/301 |
| 🇪🇺 EU | 1518.00.40.00 |
0% | None | No additional duties |
| 🇦🇺 Australia | 1518.00.40.00 |
5% | None | No IEEPA |
| 🇯🇵 Japan | 1518.00.40.00 |
0% | None | No additional duties |
📌 Conclusion:
- U.S. is the only market with 17.5%–25.5% total duty on Chinese-origin oleic acid.
- Non-China origin goods can avoid IEEPA + 301 duties.
📌 Six, Common Mistakes & How to Avoid Them
❌ Mistake 1: Using 1518.00.40.00 for distilled-only oleic acid
👉 Result: Pay 25.5% instead of 17.5% → overpay by 8%
❌ Mistake 2: Not disclosing process method in invoice
👉 Result: Customs may classify as chemically modified → higher duty
❌ Mistake 3: Using “oleic acid” without specifying purity or process
👉 Result: Risk of misclassification, audit, penalties
❌ Mistake 4: Shipping in small batches from China → still no de minimis relief
👉 Result: Pay full 17.5%–25.5% duty
✅ Correct Declaration Example:
"Purified Oleic Acid, 98.5% purity, obtained via vacuum distillation of olive oil, no chemical modification, 50 kg in drums, Origin: Spain"
🎯 Seven, Final Verdict: Precision Pays Off
🎯 Remember the Rule:
🔹 "Process determines code, purity determines duty, China origin = 17.5%+!"
🔹 "One wrong HS code = 8% extra cost, audit risk, or seizure!"
📌 Pro Tip:
📞 Apply for an Advance Ruling (Pre-Clearance) before shipment — especially for high-volume or high-value shipments.
🚀 Use a U.S.-based customs broker with experience in fatty acids and agrochemicals.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
