π§ͺ Perfluorocarbon/Argon Mixed Gas
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Industrial Gas Compliance Strategy
π I. Product Definition & Classification: What Exactly Is "Mixed Gas"?
Perfluorocarbon/Argon Mixed Gas is a specialized industrial gas mixture widely used in high-tech manufacturing, particularly in semiconductor fabrication, plasma etching, and cleaning processes. Unlike simple elemental gases, this mixture combines the inert properties of Argon with the reactive etching capabilities of Perfluorocarbons (PFCs).
Key Distinction:
- It is not a simple mechanical mixture of air or standard welding gases; it is a chemically formulated compound designed for precise material removal (etching) in microelectronics.
- Due to the presence of fluorinated compounds, it falls under stricter environmental and safety regulations compared to inert gases like pure Argon.
β οΈ Critical Classification Logic:
- If the mixture is primarily defined by its PFC content and used for its chemical reactivity in etching, it is classified under Chemical Compounds (Chapter 28).
- If it were purely inert Argon, it would fall under 2804.29. However, the Perfluorocarbon component drives the classification toward 2843.90 (Other fluorinated compounds) or 2804.10 (Hydrogen, Helium, etc., though PFCs are not typically here unless specified as "other gases").
- Note: The provided data indicates two potential classifications based on regulatory nuance: 2804.10 (if considered a specified mixed gas) and 2843.90 (if considered a specialized fluorinated compound).
π¦ II. HS Code Classification Details (2026 Latest Tariff Alignment)
| HS Code | Product Description | Application Scenario | Key Component |
|---|---|---|---|
2804.10 |
Mixed gases, not elsewhere specified, containing perfluorocarbons and argon | Semiconductor manufacturing, plasma etching where inert/reactive balance is key | PFCs + Argon |
2843.90 |
Other fluorinated compounds, including perfluorocarbon/argon mixtures, not elsewhere specified | Specialized electronic applications requiring precise gas composition and inert characteristics | PFCs (as compound) |
π Important Note:
- The choice between 2804.10 and 2843.90 depends on the primary function and regulatory interpretation in the destination country.
- 2804.10 focuses on the mixture aspect (mixed gases).
- 2843.90 focuses on the chemical nature (fluorinated compounds).
- Both codes indicate "Failed to retrieve tax information" in the provided dataset, meaning tariff rates must be verified locally.

β 2. Declaration Tips (Key Mantras)
π₯ βGas is Hazardous, PFC is Special, HS Code Must Be Precise!β
| Situation | Correct Declaration | Wrong Practice |
|---|---|---|
| Mixed Gas (PFC+Argon) | 2804.10 or 2843.90 with SDS attached |
Misdeclare as "Argon Gas" β 2804.29 β Penalty! |
| Small Sample (De Minimis) | β Do Not Use | PFCs are often excluded from de minimis thresholds. |
| Bulk Shipment | Full customs entry with HS Code | Partial declaration β Seizure! |
β 3. Special Cases
| Situation | Handling Advice |
|---|---|
| PFC Content > 50% | Strongly recommend 2843.90 as it emphasizes the fluorinated nature. |
| PFC Content < 50% | 2804.10 may be more appropriate as a "mixed gas." |
| Hazardous Materials | Must comply with DOT/PHMSA regulations for transport. |

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
