βοΈ R125 Refrigerant (1,1,1,2,2-Pentafluoroethane)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professionalιε ³ Strategy π I. Product Definition & Classification: What is R125?
R125 (Chemical Name: 1,1,1,2,2-Pentafluoroethane, CAS No. 811-97-2) is a hydrofluorocarbon (HFC) widely used as a component in refrigerant blends (such as R410A and R507). In international trade, its classification depends heavily on whether it is imported as a pure chemical compound or as a mixture/blended refrigerant.
Two Main Categories: 1. Pure Chemical Substance (R125 Single Component): Classified under Chapter 29 (Organic Chemicals). This is the most precise classification for pure R125. 2. Mixture/Gas (Blends or Pressurized Gases): Classified under Chapter 27 (Mineral Fuels) or Chapter 38 (Miscellaneous Chemical Products), depending on packaging and formulation.
β οΈ Key Distinction Point: - If imported as a pure, specific chemical compound (1,1,1,2,2-Pentafluoroethane) βε½ε ₯ 2903.44.10.10 (Lowest Duty). - If imported as liquefied gas or petroleum gas derivatives βε½ε ₯ 2711.29.00.60 / 2711.19.00.20 (High Duty). - If imported as a refrigerant mixture (not pure R125) βε½ε ₯ 3824.99.55.00 / 3824.99.93.97 (Highest Duty).
π¦ II. HS Code Classification Details (2026 Latest Tariff Authorityε―Ήη §)
| HS Code | Product Description | Application Scenario | Chemical Nature |
|---|---|---|---|
2903.44.10.10 |
1,1,1,2,2-Pentafluoroethane (Pure R125) | Pure refrigerant gas, halogenated ethane derivative | β Pure Organic Chemical |
2711.29.00.60 |
Liquefied Petroleum Gases (LPG) / Other Gaseous Hydrocarbons | R125 treated as a gaseous hydrocarbon mixture | β Petroleum Gas Derivative |
2711.19.00.20 |
Liquefied Natural Gas & Other Gaseous Hydrocarbons | R125 treated as other gaseous hydrocarbon material | β Gaseous Hydrocarbon |
3824.99.55.00 |
Halogenated Hydrocarbon Mixtures | Refrigerant blends (e.g., R410A components) | β οΈ Mixture |
3824.99.93.97 |
Other Chemical Mixtures | Generic refrigerant mixtures not specified elsewhere | β οΈ Generic Mixture |
π Critical Reminder: - Pure R125 is an organic fluorinated compound, strictly belonging to Chapter 29. Misclassifying it as a gas (Ch 27) or mixture (Ch 38) leads to significant duty differences (13.7% vs 35-40%). - If the product is a blend (e.g., R410A), it cannot be classified under
2903.44.10.10even if it contains R125. It must go to Ch 38.

|---|---|
| Base Duty Rate | 3.7% (Ad Valorem) |
| Section 301 Surtax | 0.0% (No additional 25% tariff for this specific pure chemical code) |
| IEEPA Add-on | +10% (ιε―ΉδΈε½/ι¦ζΈ―δΊ§εοΌθͺ2025εΉ΄11ζ10ζ₯θ΅·) |

| Legal Basis Path | IEEPA:9903.01.25 β IEEPA:9903.01.24 β USITC:2903.44.10.10 |
π Explanation: - This is the most favorable classification for pure R125. - The 0% Section 301 surtax is crucial here. Many hydrofluorocarbons are subject to 25%, but pure R125 under
2903.44.10.10currently enjoys a 0% surtax rate, though it is still subject to the 10% IEEPA tariff. - Total 13.7% is significantly lower than other categories.

π οΈ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
β 1. Documentation Checklist (Essential)
| Document | Required | Explanation |
|---|---|---|
| β Chemical Certificate of Analysis (COA) | βοΈ | Must prove purity >99% and chemical name: 1,1,1,2,2-Pentafluoroethane. Crucial for Ch 29 classification. |
| β Safety Data Sheet (SDS) | βοΈ | Show UN Number (UN 3374 for refrigerants), Flash Point, and Hazard Class (2.2). |
| β Product Photos (Label & Cylinder) | βοΈ | Clear view of "R125" and "Pure Chemical" markings. |
| β Commercial Invoice | βοΈ | Declare as "R125 Refrigerant Gas, 1,1,1,2,2-Pentafluoroethane, Pure Chemical" β NOT "Refrigerant Mixture". |
| β Packing List | βοΈ | Detail net/gross weight, cylinder count. |
| β Manufacturer Declaration | βοΈ | Confirm origin and that it is not a pre-mixed blend. |
β 2. Declaration Strategy (Key Mantras)
π₯ βPure R125 = 2903, Not 2711/3824! Purity is King!β
| Scenario | Correct HS Code | Wrong Action | Consequence |
|---|---|---|---|
| Pure R125 Cylinder | 2903.44.10.10 |
Declare as "Refrigerant Gas" | Audited β Back taxes to 35-40% + Penalties |
| R410A Blend | 3824.99.55.00 |
Declare as "R125" | Customs rejects β Delay/Return |
| Unclear Origin | N/A | No COA | Treated as generic mixture β 40% Duty |
| Small Samples | N/A | Try De Minimis | Denied β Full duty applies |
π Critical Tip: - Always specify "1,1,1,2,2-Pentafluoroethane" in the description. - Do NOT use vague terms like "Refrigerant Gas" without chemical specification.
β 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| R125 in Blends (e.g., R410A) | Must use Ch 38 codes (3824.99.55.00). Pure R125 code is illegal for blends. |
| Cylinders vs. Bulk | Classification remains the same, but bulk shipments require additional UN 3374 packaging compliance. |
| Recycled R125 | If recycled, may still qualify under 2903.44.10.10 if purity meets standards, but SDS must reflect "Reclaimed". |
| EU Import | Note: EU has F-Gas regulations. R125 is a high-GWP gas. Import quotas may apply regardless of HS Code. |
π V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Duty Rate (China Origin) | Key Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 2903.44.10.10 |
13.7% | UN3374 Packaging | 10% IEEPA + 3.7% Base. Avoid Ch 27/38. |
| π¨π³ China | 2903.44.10.10 |
3.7% | No extra surtax | Low duty, but requires F-Gas permit for domestic use. |
| πͺπΊ EU | 2903.44.10.10 |
0% (if eligible) | REACH Registration | High-GWP restrictions apply. |
| π¬π§ UK | 2903.44.10.10 |
3.5% | REACH UK | Similar to EU post-Brexit. |
| π¦πΊ Australia | 2903.44.10.10 |
5% | Ozone Protection | Strict environmental controls. |
π Conclusion: - The USA has the most complex tariff structure due to IEEPA and Section 301. - Correct classification as
2903.44.10.10saves ~21-26% compared to misclassification. - China and EU have lower base rates but stricter environmental regulations on HFCs.
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Declaring R125 as "Refrigerant Mixture" (3824.99.55.00)
π Consequence: 38.7% Duty instead of 13.7%. Loss of ~25% in cost.
β Error 2: Declaring R125 as "LPG/Gas" (2711.29.00.60)
π Consequence: 35% Duty. Customs audit reveals pure chemical nature β Back taxes + Interest.
β Error 3: No Chemical Certificate of Analysis (COA)
π Consequence: Customs cannot verify purity β Default to highest duty code (3824.99.93.97 β 40%).
β Error 4: Using "R125" without chemical name π Consequence: Ambiguous declaration β Delay at border for inspection.
β Correct Declaration Example:
"R125 Refrigerant Gas, Pure Chemical: 1,1,1,2,2-Pentafluoroethane, CAS 811-97-2, Purity β₯99.9%, UN3374, Net Weight 15kg per Cylinder."
π― VII. Conclusion: Precise Classification Saves Money!
π― Remember the Mantra:
πΉ βPure R125 is Ch 29, Not Ch 27 or 38! 13.7% vs 40%, Choose Wisely!β πΉ βProvide COA, Specify Chemical Name, Avoid Mixture Codes!β
π Pro Tip:
- If importing blends (R410A, R404A), ensure the SDS explicitly states it is a mixture, not a pure compound.
- For USA imports, consider applying for a Pre-Ruling (CBP Ruling) if importing large volumes regularly, to lock in the 2903.44.10.10 classification and mitigate audit risks.
π£ Immediate Action:
π Consult your customs broker with the SDS and COA. π Declare as
2903.44.10.10for pure R125 to maximize profit margins.

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
