🏭 Mold Release Agent (外壳脱模剂)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 Part 1: Product Definition & Classification: Do You Truly Understand "Mold Release Agent"?
Mold Release Agent (外壳脱模剂) is a critical chemical auxiliary agent used in the manufacturing of plastic shells, automotive parts, and industrial components. Its primary function is to prevent the molded product (plastic shell) from sticking to the mold during the injection molding or casting process.
In international trade, the classification is tricky because it depends on chemical composition and primary function:
Type A: Polishing/Cleaning/Based Agents
If the agent functions primarily as a cleaner, polish, or contains glycerol/lipids for surface treatment, it falls under Chapter 34.
Type B: Industrial Chemical Preparation
If it is a specialized industrial chemical mixture (silicone, fluorocarbon, or other organic compounds) designed specifically for release properties with no other specific heading, it falls under Chapter 38.
⚠️ Key Distinction Point:
- If the product is marketed as a "cleaner/polish" or has a glycerol base →归入 3405.10
- If it is a specialized "industrial chemical preparation" (e.g., silicone spray, fluoropolymer emulsion) used strictly for release → 归入 3824.90 or 3824.10 (if it acts as a binder).
📦 Part 2: Detailed HS Code Classification (2026 Latest Tariff Authority)
Based on the provided <DATA>, here are the relevant HS Codes and their descriptions:
| HS Code | Product Description | Applicable Scenario | Key Characteristics |
|---|---|---|---|
3405.10 |

Base: Glycerol/Cream. |
3824.90 |
Prepared binders for foundry molds or cores; chemical products and preparations... not elsewhere specified or included... applicable to "Mold Release Agent" as a specialized industrial chemical preparation. | General industrial chemical release agents (e.g., silicone, wax blends) not fitting Chapter 34. | Function: Industrial Release. Type: Unspecified Chemical Mixture. |
3824.10.00.00 |
Prepared binders for foundry molds or cores. | Specific Use Case: If the release agent is primarily used as a binder for foundry molds (sand molds) rather than plastic shells. | Specificity: High. Use: Foundry/Metal Casting. |
3824.99.29.00 |
Chemical products... Other: Other: Other: Mixtures containing 5% or more by weight of aromatic or modified aromatic substances. | Release agents containing significant aromatic components (e.g., certain solvent-based sprays). | Composition: ≥5% Aromatic substances. |
🔍 Crucial Reminder:
- Plastic Shell Release Agents are most commonly classified under 3405.10 (if creamy/glycerol-based) or 3824.90 (if specialized chemical sprays).
- Foundry/Metal Mold Binders go to 3824.10.
- Do not confuse "Release Agent" with "Cleaning Agent". If it cleans the mold and releases, check the primary function.

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
