๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
๐ I. Product Definition & Classification: What Exactly is a "Refrigerant Mixing Tank"?
In international trade, a "Refrigerant Mixing Tank" typically refers to containers or vessels holding Refrigerant Mixtures (blends of hydrocarbons, halocarbons, or inorganic compounds). The customs classification depends heavily on the chemical composition and state of the substance inside.
โ ๏ธ Key Distinction:
- Is it a Halogenated Hydrocarbon (Organic)? โ Look at Chapter 29.
- Is it a Chemical Preparation/Compound? โ Look at Chapter 38.
- Is it an Inorganic Compound? โ Look at Chapter 28.
- Is it a Tank/Vessel itself (empty)? โ Not covered in , but usually Chapter 73 or 39. Note: The provided focuses on the content (the refrigerant mixture) being imported.
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided , the refrigerant mixtures fall into five specific HS Codes. Below is the detailed breakdown.
| HS Code | Product Description (Summary from Data) | Chemical Nature | Total Tax Rate |
|---|---|---|---|
3824.99.55.00 |
Refers to halogenated hydrocarbon mixtures, classified under chemical preparations. | Organic Chemical Preparation | 38.7% |
3824.99.50.00 |
Meets characteristics of chemical products/preparations containing halogenated hydrocarbons. | Halogenated Hydrocarbon Preparation | 41.5% |
2903.79.90.70 |
Non-cyclic hydrocarbon halogenated derivatives containing multiple halogens. | Organic Halogenated Compound | 38.7% |
2903.49.00.00 |
Halogenated hydrocarbon derivatives containing fluorine or chlorine. | Fluorine/Chlorine Derivative | 13.7% |
2853.90.90.90 |
Classified under other inorganic compounds. | Inorganic Compound | 37.8% |
๐ Key Insight:
-2903.49.00.00offers the lowest tax burden (13.7%) if the mixture is strictly defined as a fluorine/chlorine derivative.
-3824.99.50.00carries the highest burden (41.5%) due to higher base tariffs when classified broadly as a chemical preparation.
- The distinction between Chapter 28 (Inorganic) and Chapter 29 (Organic) is critical for chemical composition proof.

๐ ๏ธ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
โ 1. Documentation Checklist (Non-Negotiable)
| Document | Required? | Purpose |
|---|---|---|
| โ Chemical Structure Formula | โ๏ธ | Proves organic/inorganic nature. Critical for 2903 vs 3824. |
| โ Safety Data Sheet (SDS) | โ๏ธ | Shows composition, CAS numbers, and physical state. |
| โ Certificate of Analysis (COA) | โ๏ธ | Confirms purity and mixture ratios. |
| โ Commercial Invoice | โ๏ธ | Must clearly state "Refrigerant Mixture" + HS Code. |
| โ Declaration of Content | โ๏ธ | Explicitly state "Contains Fluorine/Chlorine derivatives" if aiming for 2903.49.00.00. |
| โ Packaging Details | โ๏ธ | Ensure tanks/vessels are rated for pressure and compliant with DOT/UN standards. |
โ 2. Declaration Strategy (Key Formulas)
๐ฅ "Prove the Chemistry, Not the Container!"
If you import the mixture, declare based on chemistry. If you import the empty tank, declare as metal/plastic vessel.
| Scenario | Recommended HS Code | Tax Rate | Why? |
|---|---|---|---|
| Mixture is primarily F/Cl derivative | 2903.49.00.00 |
13.7% | Lowest tax. Requires strong chemical proof. |
| Mixture is complex organic prep | 3824.99.55.00 |
38.7% | Safe fallback for complex blends. |
| Mixture is inorganic (e.g., Ammonia mix) | 2853.90.90.90 |
37.8% | For non-carbon based mixtures. |
| Mixture is vague/unspecified prep | 3824.99.50.00 |
41.5% | Avoid! Highest tax. |
โ 3. Special Handling Notes
| Situation | Advice |
|---|---|
| Customs Audit on Chemistry | Be ready to provide CAS numbers for each component. If itโs a blend, list all components. |
| Empty Refrigerant Tanks | Do not declare as 3824 or 2903. These are for the content. Empty tanks are usually Chapter 73 (Steel) or 39 (Plastic). |
| Section 122 Impact | Even if you save on Section 301 (like in 2903.49.00.00), the 10% Section 122 still applies. Do not assume full exemption. |
| Misclassification Risk | Declaring 2903.49.00.00 without proof can lead to re-classification to 3824.99.50.00 (41.5%) + penalties. |
๐ V. Global Market Comparison (2026 Overview)
| Country/Region | Recommended HS Code | Approx. Duty | Notes |

๐ VI. Common Errors & Pitfalls (Lessons Learned)
โ Error 1: Declaring refrigerant as "Chemical Mixture" (Vague)
๐ Result: Customs defaults to 3824.99.50.00 (41.5%).
โ
Fix: Provide exact chemical names (e.g., "Chlorotrifluoroethane derivative").
โ Error 2: Confusing "Empty Tank" with "Refrigerant"
๐ Result: Wrong HS code, shipment delay.
โ
Fix: Separate invoices for empty tanks and full refrigerant.
โ Error 3: Ignoring Section 122
๐ Result: Underestimating costs. Even 2903.49.00.00 has 10% surcharge.
โ
Fix: Budget for 13.7% total for the best-case scenario.
๐ฏ VII. Conclusion: Smart Classification, Lower Costs
๐ฏ Remember:
๐น "Chemistry is King": Prove it's a
2903derivative to save 28% in taxes.
๐น "Section 122 is Persistent": The 10% surcharge applies almost everywhere now.
๐น "Documentation is Defense": SDS, COA, and CAS numbers are your best friends.

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) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ 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 โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
