🖥️ PFC Refrigerant Compounds (Perfluorocarbons)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Strategy 📌 I. Product Definition & Classification: Do You Truly Understand "PFCs"?
Perfluorocarbons (PFCs) are synthetic fluorinated gases composed entirely of carbon and fluorine. In international trade, they are primarily classified based on their end-use: whether they are used as refrigerants/propellants (Chapter 84/85/90 logic) or as raw chemical materials (Chapter 29 logic).
⚠️ Critical Distinction for Classification: - PFC Gases (Raw/Industrial Grade): If sold as a bulk chemical or raw material, regardless of its cooling properties, it typically falls under Chapter 29 (Organic Chemicals). Specifically, 2903.49 (Halogenated derivatives of hydrocarbons). - PFC Blends/Compositions for Refrigeration: If explicitly marketed and formulated as "Refrigerants" or "Propellants," they may be classified under Chapter 84 (Machinery parts) or Chapter 38 (Miscellaneous chemical products), but 2903.49 is the most common and defensible classification for pure PFC compounds unless they are specific blends with trade names that dictate a different heading (e.g., 3824 for prepared binders, though rare for pure PFCs). - Pre-charged Cylinders/Units: If the PFC is contained in a cylinder for retail sale as a complete refrigerant product, it might fall under 8415.90 (Parts of air conditioners) or 3824.99 depending on national interpretation, but 2903.49 remains the standard for the substance itself.
Key Differentiator: - Pure PFC chemical (R-14, R-23, R-116, etc.) → 2903.49 - Pre-mixed refrigerant blends (often HFCs, but if PFC-based) → Check specific formulation; often 3824 or 2903.49 - For this guide, we focus on Pure PFC Compounds as the primary input for refrigeration systems.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Application Scenario | Contains PFC? |
|---|---|---|---|
2903.49.00.00 |
Other halogenated derivatives of acyclic hydrocarbons | Pure PFC gases (e.g., Tetrafluoromethane R-14, Trifluoromethane R-23, Hexafluoroethane R-116), industrial refrigerants, semiconductor etching gases | ✅ Yes (Pure Chemical) |
3824.99.99.00 |
Prepared binders for foundry molds; chemical products and preparations | Mixed refrigerant formulations, propellant blends containing PFCs, where the composition makes it a "prepared" chemical rather than a pure substance | ✅ Yes (Mixed) |
8415.90.00.00 |
Parts of air conditioning machines | Pre-charged cylinders of refrigerant sold as accessories to specific AC units (Rare for pure PFCs, more common for R-410A/R-32 blends) | ✅ Yes (as part of assembly) |
2903.39.00.00 |
Halogenated derivatives of cyclic hydrocarbons | Cyclic PFCs (e.g., Perfluorocyclobutane R-1276) – less common than linear PFCs | ✅ Yes (Cyclic) |
🔍 Key Reminder: - PFCs are potent Greenhouse Gases (GHGs). Many jurisdictions require special permits for import/export due to climate regulations (Kigali Amendment to Montreal Protocol). - Do not misclassify PFC refrigerants as general "chemicals" without mentioning their environmental impact. Customs may flag them for environmental compliance. - If the product is a blended refrigerant (e.g., a proprietary mix for cryogenic cooling), check if it fits 3824.99 as a "preparation."

| USITC Surtax | +25% (from USITC Footnote 9903.88.01 – Section 301 tariffs on Chinese goods) |
| IEEPA Surcharge | +10% (China/HK products under IEEPA, effective Nov 10, 2025) |
| Total Duty Rate | 35% |
| Tax Calculation | CIF Value × 35% |
| De Minimis Eligibility | ❌ Denied (deny_de_minimis) – PFCs are regulated chemicals |
| Legal Pathway | IEEPA:9903.01.25 → IEEPA:9903.01.24 → USITC:2903.49.00.00 → FOOTNOTE:9903.88.01 |
📌 Explanation: - The 25% USITC surcharge applies because PFCs from China are subject to Section 301 tariffs. - The 10% IEEPA surcharge is a new layer for Chinese-origin goods starting Nov 10, 2025. - Total 35% is significant for high-value refrigerants. - Environmental Fees: Additional EPA fees or recycling taxes may apply depending on the volume and GHG intensity.
🎯 2. 3824.99.99.00 – Prepared Chemical Products (Refrigerant Blends)
| Item | Details |
|---|---|
| Base Duty Rate | 5.3% (standard MFN rate for misc. chemical preparations) |
| USITC Surtax | +25% (if from China, subject to Section 301) |
| IEEPA Surcharge | +10% (if from China, IEEPA 2025 rules) |
| Total Duty Rate | 40.3% |
| Tax Calculation | CIF Value × 40.3% |
| De Minimis Eligibility | ❌ Denied |
| Legal Pathway | IEEPA:9901.25 → IEEPA:9903.01.24 → USITC:3824.99.99.00 → FOOTNOTE:9903.88.01 |
📌 Note: - If your PFC is part of a blended refrigerant (e.g., mixed with HFCs or hydrocarbons), it may be classified here. - The base rate is higher (5.3% vs 0%), but the surcharges are the same, resulting in a higher total duty (40.3%). - Strategy: If you can prove the product is a pure chemical (
2903.49), the total duty is 35%, which is 5.3% cheaper than classifying it as a blend.

| Document | Must Provide | Description |
|---|---|---|
| ✅ Safety Data Sheet (SDS) | ✔️ | Must explicitly state chemical composition, CAS numbers, and GHG properties |
| ✅ Certificate of Analysis (CoA) | ✔️ | Purity levels, confirming if it's pure PFC or a blend |
| ✅ Product Specification Sheet | ✔️ | CAS numbers (e.g., 75-73-0 for R-14), molecular formula |
| ✅ Environmental Compliance Permit | ✔️ | EPA registration or import permit for fluorinated gases (if required by destination) |
| ✅ Commercial Invoice | ✔️ | Clearly state "PFC Refrigerant Gas" + HS Code + CAS Number |
| ✅ Packing List | ✔️ | Weight, volume, cylinder pressure (if pressurized) |
| ✅ Dangerous Goods Declaration | ✔️ | PFCs are often classified as Class 2.2 (Non-flammable, Non-toxic Gas) under IMDG/IATA |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Pure PFC is 2903, Blend is 3824, Cylinder is 8415. Name it right, save thousands!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Pure R-14 Gas | 2903.49.00.00 "Perfluoromethane (R-14)" |
"Refrigerant Gas" → Risk of audit |
| R-14 in Cylinder | 2903.49.00.00 "Refrigerant Gas, not for retail" |
8415.90 "AC Part" → Misclassification penalty |
| Custom Blend | 3824.99.99.00 "Prepared Refrigerant Mixture" |
2903.49 "Pure Chemical" → If impurities exist |
| Bulk Liquid | 2903.49.00.00 "Liquid PFC, Industrial Grade" |
"Chemical Solvent" → Incorrect end-use |
✅ 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| Pre-charged Cylinders | Declare as Refrigerant (2903.49), not as a part. If sold with AC unit, value apportionment may be required. |
| EPA/EU Environmental Taxes | PFCs have high Global Warming Potential (GWP). Expect additional environmental levies in EU/US beyond customs duty. |
| Transshipment via Vietnam/Malaysia | High Risk. US Customs scrutinizes transshipped chemicals for origin fraud. Ensure proper Substantial Transformation proof or Non-Originating Material disclosure. |
| Small Sample Shipments | Even samples require full documentation. De Minimis does not apply to regulated chemicals. |

📌 VI. Common Errors & Pitfall Guide (Blood-Teaching Lessons)
❌ Error 1: Declaring PFCs as "Chemical Solvent" (2905.99)
👉 Consequence: Misclassification → 35%+ duty + fines + seizure.
❌ Error 2: Splitting a pre-charged cylinder into "Gas + Cylinder"
👉 Consequence: Cylinder declared as metal (low duty) → Fraud alert → Total seizure.
❌ Error 3: Ignoring EPA/Environmental Permits
👉 Consequence: Customs holds shipment for EPA review → Delay of 30-60 days.
❌ Error 4: Using "Refrigerant" without CAS Number
👉 Consequence: Customs cannot verify HS Code → Red Box Inspection → High chance of penalty.
✅ Correct Practice:
"PFC Refrigerant Gas, Pure Perfluoromethane (R-14), CAS 75-73-0, HS 2903.49.00.00, EPA Reg. No. XXXXX, Net Weight 50kg, Non-Flammable Gas"

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
