🧯 Carbon Dioxide Fire Extinguishing Agent (CO₂)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "CO₂ Fire Extinguisher"?
Carbon Dioxide (CO₂) Fire Extinguishing Agent is a clean, non-conductive, gas-based extinguishing medium used primarily in electrical, electronic, and flammable liquid fire suppression systems. In international trade, its classification hinges on two critical factors: 1. Form: Is it pure chemical gas or a prepared mixture? 2. Usage: Is it intended for general chemical use or specifically packaged/identified as fire suppressant?
⚠️ Key Distinction Point:
- Pure CO₂ Gas: Classified under Chapter 28 (Inorganic Chemicals).
- Prepared Fire Extinguishants: Classified under Chapter 38 (Miscellaneous Chemical Products), specifically for fire extinguishers.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Alignment)
Based on the provided data, here are the valid HS Code options with detailed tax implications:
| HS Code | Product Description | Application Scenario | Reason for Classification |
|---|---|---|---|
2811.21.00.00 |
Carbon Dioxide (Inorganic Non-Metallic Oxide) | Bulk industrial CO₂, pure gas cylinders | Direct Match: The name explicitly contains "Carbon Dioxide," fitting the inorganic oxide category perfectly. |
2811.19.61.90 |
Other Inorganic Oxides of Non-Metals | Industrial grade CO₂ not specifically listed elsewhere | Broad Category: Falls under "Other inorganic acids & non-metallic oxides." No material conflict. |
3813.00.10.00 |
Fire Extinguishant Charges | Pre-filled cylinders, specific fire suppression formulations | Usage-Based: Matches usage (fire extinguishing) and inferred composition (CO₂ as inorganic chemical). Zero base duty makes this attractive for pure CO₂ charges. |
3813.00.50.00 |
Other Fire Extinguishants | Mixed agents or specific branded fire suppressants | Usage-Based: Matches usage & material. Higher base duty (3.7%) but same added tariffs. |
3813.00.10.00 |
Fire Extinguisher Charges | Rechargeable CO₂ cylinders, specific agent forms | Usage + Form: Matches usage (fire extinguishing) and common sense inference (charged agent form). Consistent with Chapter 38 definitions. |
🔍 Critical Reminder:
- If the product is pure CO₂ sold as a chemical raw material,2811.21.00.00is the most direct legal fit.
- If the product is packaged for firefighting (e.g., extinguisher cartridges, portable tanks),3813.00.10.00is often preferred for its 0% base tariff, despite the added taxes.
- Do not misdeclare a pure chemical gas as a "fire extinguishant" unless it is legally defined as such in its packaging and intended use.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes & Policy Add-ons)
✅ Applicable Country: USA (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (for subsequent imports)
🎯 1. 2811.21.00.00 — Carbon Dioxide (Pure Chemical)
| Item | Detail |
|---|---|
| Base Duty | 3.7% |
| Section 301 Surcharge | +25.0% |
| Section 122 Clause Tax | +10.0% |

📌 Explanation:
- This is the standard classification for pure CO₂.
- While the base duty is low, the added tariffs (35% total added) make it expensive.
- Suitable for bulk industrial supply where fire-fighting packaging is not the primary intent.
🎯 2. 2811.19.61.90 — Other Inorganic Non-Metallic Oxides
| Item | Detail |
|---|---|
| Base Duty | 4.2% |
| Section 301 Surcharge | +25.0% |
| Section 122 Clause Tax | +10.0% |
| Total Effective Rate | 39.2% |
| Calculation | CIF Value × 39.2% |
| De Minimis Eligibility | ❌ Not Eligible |

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
✅ 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify chemical composition (100% CO₂?), purity, and phase (gas/liquid). |
| ✅ Certificate of Analysis (COA) | ✔️ | Lab report confirming CO₂ purity and absence of hazardous contaminants. |
| ✅ Safety Data Sheet (SDS) | ✔️ | Section 14 must indicate UN1044 (Carbon Dioxide, compressed or refrigerated liquid). |
| ✅ Commercial Invoice | ✔️ | Clearly state: "Carbon Dioxide, Fire Extinguishing Agent" OR "Industrial Carbon Dioxide Gas." |
| ✅ Packing List | ✔️ | Detail cylinder weight, gas weight, and pressure ratings. |
| ✅ UN Packaging Certification | ✔️ | Crucial for gases. Must show compliant pressurized containers. |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Form Determines Chapter, Usage Determines Subheading!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Pure CO₂ in bulk tanks | 2811.21.00.00Desc: "Carbon Dioxide, Inorganic Gas" |
Calling it "Fire Extinguisher" → Misclassification penalty. |
| CO₂ in extinguisher cartridges | 3813.00.10.00Desc: "Fire Extinguishing Agent, CO₂ Based" |
Using 2811 → Higher tax (38.7% vs 35.0%). |
| Mixed chemical fire suppressant | 3813.00.50.00Desc: "Other Fire Extinguishing Agent" |
Claiming it's pure CO₂ → Fraud risk. |
| CO₂ for beverage carbonation | 2811.21.00.00Desc: "Food Grade Carbon Dioxide" |
Declaring as fire agent → Inspection delay. |
✅ 3. Special Case Handling
| Case | Handling Suggestion |
|---|---|
| Rechargeable CO₂ Cylinders | If sold empty, declare as "Parts of Fire Extinguishers" (often lower duty). If filled, declare as 3813.00.10.00. |
| Mixed Gases (e.g., CO₂ + Nitrogen) | Cannot use 2811.21.00.00. Must use 3813.00.50.00 or other chemical mixtures. |
| Liquid CO₂ (Refrigerated) | Ensure SDS indicates UN1044. Customs may request additional pressure vessel certification. |
| Small Quantity Samples | Even small quantities of Class 2.2 Gases are subject to strict customs inspection. No de minimis exemption. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Remarks |

📌 Conclusion:
- USA is the most tax-sensitive market for CO₂ due to Section 301 and 122 clauses.
- Choosing3813.00.10.00saves 3.7% compared to2811.21.00.00, provided the product is legitimately a fire extinguishing agent.
- Misclassification is high-risk: Claiming industrial gas as fire agent without proper packaging/use proof can lead to seizure.
📌 VI. Common Mistakes & Pitfall Guide (Blood & Tears Lessons)
❌ Mistake 1: Declaring "Carbon Dioxide" (Chemical) when it's actually "Fire Extinguisher Charges"
👉 Consequence: Overpaying 3.7% on CIF value. Missed savings!
❌ Mistake 2: Declaring "Fire Extinguishing Agent" when it's pure industrial CO₂
👉 Consequence: Customs may reject the declaration if UN packaging or fire-specific labeling is absent. Delay + Penalty!
❌ Mistake 3: Omitting UN1044 in description
👉 Consequence: Immediate hold by CPB (Customs and Border Protection) for dangerous goods verification.
❌ Mistake 4: Using "CO₂ Gas" for mixed agents
👉 Consequence: Fraud. Must declare actual composition.
✅ Correct Practice:
For USA Import:
"Fire Extinguishing Agent, Carbon Dioxide Based, Filled in Compressed Cylinders, UN1044, HS Code 3813.00.10.00"
🎯 VII. Conclusion: Precise Classification, Maximize Savings!
🎯 Remember the Mantra:
🔹 "Pure Gas = 2811 (38.7%); Fire Agent = 3813 (35.0%). Save 3.7% if valid!"
🔹 "HS Code decides cost, Tariff adds stress. Get it right, sleep well!"
📌 Pro Tip:
If your CO₂ is originating from Vietnam, Mexico, or Thailand, check for USMCA/FTA exemptions or reduced Section 301 rates. Always apply for a Binding Ruling (Pre-Clearance) before shipping high-volume CO₂ consignments to the US.

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
