π§ͺ Methyl Chloroform (Chlorobromomethane) Laboratory Reagent
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
π I. Product Definition & Classification: Do You Really Understand "Methyl Chloroform"?
Methyl Chloroform, chemically known as Chlorobromomethane (CHβClBr), is a simple halogenated organic compound. In international trade, it is classified based on its chemical structure: - It contains both Chlorine and Bromine atoms attached to a single carbon atom. - It is an organic compound (haloalkane) but also exhibits properties of inorganic halides in certain chemical contexts.
β οΈ Key Distinction Point:
- If classified as an inorganic halide β It falls under Chapter 28 (Inorganic Chemicals).
- If classified as an organic halide β It falls under Chapter 29 (Organic Chemicals).
- If classified as a mixture/preparation β It falls under Chapter 38.

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
