🧪 Fatty Acid Esters / Fatty Substances (Ethanol Esters)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What Exactly Are "Fatty Acid Esters"?
"Fatty Acid Esters" (often referred to as Fatty Acid Alkyl Esters, e.g., Ethyl Oleate, Methyl Ester) are chemical compounds derived from the esterification reaction of fatty acids (from animal, vegetable, or microbial sources) and alcohols. In international trade, these products are strictly regulated based on their degree of chemical modification and intended use.
They are generally categorized into two main groups:
1. Chemically Modified Fats/Oils (Heading 1518): Fats or oils that have been chemically altered (boiled, oxidized, dehydrated, sulfurized, blown, polymerized, etc.) excluding those covered under Heading 1516 (partially hydrogenated, inter-esterified, etc.). If the esterification process results in a product that fits this description of "chemically modified fats and oils," it falls here.
2. Chemical Preparations/Binders (Heading 3824): If the fatty acid ester is used as a binder for foundry molds, or is a mixture/preparation not specified elsewhere (e.g., as a solvent, plasticizer, or industrial lubricant), it falls under Chapter 38. Specifically, "Fatty substances of animal or vegetable origin and mixtures thereof" under Heading 3824.
⚠️ Critical Distinction:
- If the product is a pure, chemically modified fat/oil (e.g., polymerized linseed oil) → HS 1518.
- If the product is a chemical preparation, mixture, or industrial binder containing fatty substances → HS 3824.
- Note: Pure biodiesel (FAME) usually falls under HS 1516 or 3824 depending on purity and use, but "Fatty Acid Esters" in a general chemical context often lean towards 3824 if used as intermediates or binders. The provided data highlights 3824 codes for "fatty substances... mixtures."

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
