π§ͺ Halogenated Methane Derivative Mixture
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
π I. Product Definition & Classification: Do You Really Understand "Halogenated Methane Mixture"?
Halogenated methane mixtures (including chloromethanes, fluoromethanes, etc.) are organic chemical compounds where one or more hydrogen atoms in methane are replaced by halogen atoms (F, Cl, Br, I). In international trade, these substances are primarily used as: 1. Refrigerants & Propellants: In HVAC systems and aerosols. 2. Chemical Intermediates: For synthesizing other organic compounds. 3. Solvents & Cleaning Agents: Industrial degreasing and precision cleaning.
β οΈ Key Classification Distinction:
- Pure Halogenated Hydrocarbons: Single-component specific halogenated compounds β Generally fall under Chapter 29 (Organic Chemicals).
- Mixtures/Preparations: Mixture of halogenated methanes, or mixtures with other non-chemical carriers β May fall under Chapter 38 (Miscellaneous Chemical Products) if they do not meet the definition of a specific single chemical entity in Chapter 29.
- "Catch-all" Nature: Since specific HS codes for "Methane Derivative Mixtures" are rare, classification often relies on "Other" subheadings based on material attributes (organic vs. industrial preparation).

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
