☣️ Carbon Tetrachloride Toxicology Research Reagent (CCl₄)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Understanding "Carbon Tetrachloride"
Carbon Tetrachloride (CCl₄) is a dense, non-flammable liquid historically used as a solvent, cleaning agent, and chemical intermediate. In modern trade, it is primarily categorized based on its purity and intended use:
- Pure Chemical (Solvent/Intermediate): High-purity CCl₄ used as a raw material or industrial solvent.
- Laboratory/Toxicology Reagent: CCl₄ formulated or sold specifically for diagnostic, analytical, or biological research purposes.
⚠️ Key Distinction Point:
- If the product is bulk chemical grade or industrial solvent → It falls under Chapter 29 (Organic Chemicals).
- If the product is explicitly labeled for laboratory testing, diagnostic, or toxicology research (even if pure), it may qualify for Chapter 38 (Miscellaneous Chemical Products).

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
