🐄 Animal Fat for Casting (Animal Oils/Fats for Mould Preforms)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition and Classification: Do You Understand "Animal Fat for Casting"?
Animal fat for casting refers to processed animal-derived fats or greases specifically formulated and used as pre-formed binders or moulding agents in metal casting, foundry, and molding processes. In international trade, these products are classified based on their chemical origin (animal fat) and functional application (binder/adhesive for molds).
The core distinction lies in whether the product is defined primarily by its biological material (Chapter 38) or its chemical adhesive properties (Chapter 35).
⚠️ Key Distinction Point: - If the product is primarily recognized as a modified animal fat substance used as a binder → Classify under Chapter 38 (Miscellaneous Chemical Products). - If the product is primarily recognized as a prepared adhesive based on animal glues/proteins → Classify under Chapter 35 (Albuminoidal Substances; Modified Starches; Glues).

📌 Explanation: - Both
3824.99.41.90and3824.99.41.40share the same tax structure. - The 39.6% rate is a composite of the base tariff and two significant additional tariffs. - Section 122 (10%) specifically targets certain binding agents and adhesives, adding a substantial burden. - Section 301 (25%) is the standard USITC surcharge for Chinese-origin goods in this category.
🎯 2. 3506.10.50.00 —— Prepared Adhesives (Glue/Protein Based)
| Item | Content |
|---|---|
| Base Duty Rate | 2.1% (ad valorem) |
| USITC Additional Duty | +25.0% (Under USITC Footnote for Section 301) |
| Section 122 Duty | +10.0% (Specific provision for certain chemical/adhesive products) |

📌 Note: - Although the base rate is lower (2.1% vs 4.6%), the additional taxes remain the same. - This code is suitable if the product is primarily sold and used as a glue/adhesive rather than a bulk material binder. - Total 37.1% is slightly lower than the 3824 codes, but classification must be justified by the product's primary nature.
🛠️ IV. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Preparation Checklist (Indispensable)
| Material | Must Provide | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Detailed composition: % animal fat, % binder additives, melting point, viscosity. |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Crucial for chemical products; confirms flammability and hazard class. |
| ✅ Usage Statement | ✔️ | Explicitly state: "Used as a pre-formed binder for metal casting moulds." |
| ✅ Photos (Label & Container) | ✔️ | Show packaging, batch numbers, and any hazard labels. |
| ✅ Commercial Invoice | ✔️ | Describe as "Prepared Binding Agent for Foundries, Animal Fat Based" (for 3824) or "Prepared Adhesive" (for 3506). |
| ✅ Certificate of Origin | ✔️ | Required for Section 301 duty determination. |
✅ 2. Declaration Techniques (Key Mantras)
🔥 "Material Matters, Purpose Defines, Don't Split, Don't Guess!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Animal fat based binder for molds | 3824.99.41.90 / 3824.99.41.40 |
Misdeclare as generic chemical → Risk of audit |
| Glue-based adhesive for molds | 3506.10.50.00 |
Misdeclare as "food grade fat" → Severe Penalty |
| Bulk animal fat (unprocessed) | Other Chapter (e.g., 15) | Do Not declare as prepared binder if unprocessed |
| Mixed bag (Fat + Adhesive) | Declare primary function | Split declaration → Complexity & Delay |
✅ 3. Special Case Handling
| Scenario | Handling Advice |
|---|---|
| OEM Custom Binders | Provide client contracts and technical datasheets to prove "prepared binding agent" status. |
| Mixed Ingredients | If >50% by weight is animal fat, prefer 3824 codes; if glue/protein is dominant, use 3506. |

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
