π§ͺ Carbon Tetrachloride Fluorine Solvent (High Purity) β The "Discontinued" Hazardous Chemical
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
π I. Product Definition & Classification: Is "Carbon Tetrachloride" Still a Valid Entry?
β οΈ CRITICAL WARNING:
Carbon Tetrachloride ($CCl_4$) is a banned/phased-out substance under the Montreal Protocol and widely restricted globally due to its ozone-depleting properties and high toxicity.
True "Carbon Tetrachloride" cannot be legally imported into most major markets (US, EU, China) for general commercial use.
If the user input implies "Fluorine Solvents" (e.g., Hydrofluorocarbons - HFCs, or Fluorinated Solvents like $C_2ClF_3$), these are completely different chemicals with distinct HS codes and tariffs.
Assumption for this guide:
We will analyze two scenarios:
1. Scenario A: The user actually means Fluorinated Solvents (e.g., HCFCs, HFCs, or perfluorinated compounds) β This is the likely intent for "Fluorine Solvent".
2. Scenario B: The user insists on Carbon Tetrachloride β This will result in immediate seizure or requires special hazardous waste permits.
π Key Distinction:
- Fluorine Solvents (HFCs/HCFCs): Contain Fluorine, used in electronics cleaning, refrigeration.
- Carbon Tetrachloride: Contains only Carbon & Chlorine. Banned.
π¦ II. HS Code Classification Details (2026 Latest Tariff Matrix)
| HS Code | Product Description | Scenario | Notes |
|---|---|---|---|
2903.43.00.00 |
Perchloroethylene (Tetrachloroethylene) | If mislabeled as "Tetrachloride" | Common solvent, regulated |
2903.29.00.00 |
Other Halogenated Hydrocarbons (e.g., Fluorinated solvents) | β Most Likely | Covers HFCs, HCFCs, perfluorocarbons |
2903.49.00.00 |
Other Chlorinated Hydrocarbons | If Chlorine-based | Includes some fluorinated-chlorinated blends |
3824.99.92.00 |
Chemical Products and Preparations | Mixtures | For non-pure solvent mixtures |
2903.41.00.00 |
Trichlorofluoromethane (CFC-11) | β Banned | Ozone-depleting |
2903.49.10.00 |
Tetrachloromethane (Carbon Tetrachloride) | β Banned/Restricted | High toxicity, Montreal Protocol |
π Critical Clarification:
- "Carbon Tetrachloride" (Tetrachloromethane) is classified under2903.49.10.00(US) or similar national codes. It is largely prohibited.
- "Fluorine Solvents" typically fall under2903.29.00.00(Halogenated hydrocarbons containing fluorine) or2903.49.00.00if they are chlorofluorocarbons (CFCs/HCFCs).
- High Purity does NOT change the HS code. It affects the tariff rate (sometimes) and regulatory scrutiny.

π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
β 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Notes |
|---|---|---|
| β Material Safety Data Sheet (MSDS) | βοΈ | Must include CAS number, purity, hazard classes |
| β EPA Import Certificate | βοΈ | For all halogenated hydrocarbons |
| β Certificate of Analysis (COA) | βοΈ | To prove "High Purity" and correct composition |
| β EPA 8700-12 Form | βοΈ | Required for ozone-depleting substances |
| β Commercial Invoice | βοΈ | Must specify exact chemical name (CAS #) |
| β Packing List | βοΈ | Net/Gross weight, hazard label visibility |
| β Letter of Non-Destruction (if applicable) | β | Only if exempted |
β 2. Declaration Tips (Key Mantra)
π₯ "CAS # is King, Purity is Truth, EPA Permit is Life!"
| Scenario | Correct Declaration | Error to Avoid |
|---|---|---|
| Fluorinated Solvent | 2903.29.00.00 + CAS #127-37-9 (example) |
Vague name "Fluorine Solvent" |
| Carbon Tetrachloride | 2903.49.10.00 + EPA Permit |
Claiming "Industrial Grade" without permit |
| Mixture | 3824.99.92.00 |
Misdeclaring as pure chemical |
| High Purity (>99%) | Emphasize in COA | Hiding impurities that trigger additional bans |
β 3. Special Handling
| Situation | Action |
|---|---|
| Ozone-Depleting Substances (ODS) | Must register with EPA, pay Ozone Depleting Substance Tax (if applicable) |
| High Purity Electronics Grade | May qualify for HTS 2903.29.00.00 but still requires EPA approval |
| Shipment to US | Subject to Section 301 and IEEPA surcharges |
| Shipment to EU | Subject to REACH regulation, may require registration |
π V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ US | 2903.29.00.00 |
40.7% | EPA + OSHA | High scrutiny |
| π¨π³ China | 2903.29.00.00 |

0-6% | UK REACH | Post-Brexit rules |
π Conclusion:
- US: High tariff (40.7%) + EPA bureaucracy.
- EU: REACH compliance is the biggest hurdle.
- Carbon Tetrachloride: Do not import unless you have specific industrial exemptions (e.g., analytical laboratory use only).
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Using "Fluorine Solvent" as a generic name
π Consequence: Customs will delay shipment for 30+ days to identify CAS number.
β
Fix: Use exact IUPAC name and CAS number (e.g., Trifluoromethane, CAS# 75-10-5).
β Error 2: Ignoring EPA Permit for ODS
π Consequence: Shipment seized, fines up to $50,000 per day.
β
Fix: Secure EPA import certificate before shipment.
β Error 3: Misdeclaring "High Purity" to avoid regulation
π Consequence: False declaration, legal liability.
β
Fix: Declare true purity and composition.
β Error 4: Assuming "Fluorine Solvent" is exempt from 301 tariffs
π Consequence: Underpayment of duties, post-audit penalties.
β
Fix: Apply full 301 + IEEPA tariffs.
π― VII. Conclusion: Precision is Profit, Compliance is Survival
π― Remember:
πΉ "CAS # defines HS, EPA defines legality, Tariff defines cost."
πΉ "Carbon Tetrachloride = Banned. Fluorine Solvent = Regulated. Plan Ahead."
π Pro Tip:
- For Fluorinated Solvents, check if they are HFCs (Hydrofluorocarbons) or PFCs (Perfluorocarbons), as HFCs are subject to MAC Protocol reductions.
- Always request a pre-shipment EPA clearance to avoid port delays.
π£ Immediate Action:
π Contact your freight forwarder + Provide CAS Number + Apply for EPA Import Certificate
π Ensure your shipment clears customs without seizure or penalty!
β¨ Professional Customs Clearance Starts with Accurate Chemical Identification!
πΌ Your Compliance Cost is Lower than Your Seizure Risk!

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
