π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π I. Product Definition & Classification: Do You Really Understand "Halogenated Hydrocarbon Mixtures"?
Trichloroethane (1,1,2-Trichloroethane or Isomers) is a halogenated organic solvent widely used in laboratories for cleaning, degreasing, and chemical synthesis. In international trade, it falls under the broader category of prepared binders for foundry molds or chemical products, specifically categorized by its halogenation status.
Key Distinction:
- Chlorinated but NOT otherwise halogenated: Contains only chlorine as the halogen. β HS 3824.99.50.00
- Other Halogenated Mixtures: Contains halogens other than just chlorine (e.g., bromine, fluorine) or mixed halogens not specified elsewhere. β HS 3824.99.55.00
β οΈ Critical Note:
For "Laboratory Grade" Trichloroethane, if the mixture consists only of chlorinated hydrocarbons (no fluorine, bromine, etc.), it falls under 3824.99.50.00. If it contains other halogens or is a complex mix not specified, it may fall under 3824.99.55.00.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Halogen Type | Tax Rate (US) |
|---|---|---|---|---|
3824.99.50.00 |
Mixtures of halogenated hydrocarbons: Chlorinated but not otherwise halogenated | Pure chlorinated solvents, lab-grade trichloroethane (chlorine-only) | β Chlorine Only | 0.0% |
3824.99.55.00 |
Mixtures of halogenated hydrocarbons: Other | Halogenated mixtures with fluorine, bromine, or unspecified halogens | β Multiple/Other | 28.7% |
π Key Reminder:
- 3824.99.50.00 is for pure chlorinated mixtures.
- 3824.99.55.00 is for other halogenated mixtures (e.g., fluorinated, brominated, or mixed).
- Laboratory Grade does not exempt you from tariff classification; it depends on chemical composition.

| β Commercial Invoice | βοΈ | Accurate description: "Trichloroethane Mixture, Lab Grade, Chlorinated" |
| β Packing List | βοΈ | Net weight, gross weight, container details. |
| β HS Code Pre-Ruling | βοΈ | Highly recommended to confirm 3824.99.50.00 vs 3824.99.55.00. |
β 2. Declaration Tips (Key Mantra)
π₯ "Halogen Type Determines Tariff, Chemistry is King!"
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| Pure Trichloroethane (Cl-only) | 3824.99.50.00 |
Misdeclare as 3824.99.55.00 β 28.7% tax |
| Mixed Halogen (e.g., Cl + F) | 3824.99.55.00 |
Declare as 3824.99.50.00 β 0% β Audit Risk |

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
