π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Compliance Strategy
π Part I: Product Definition and Classification: Do You Really Understand "Carbon Tetrachloride"?
Carbon Tetrachloride (CClβ) is a dense, non-flammable liquid halocarbon once widely used in fire extinguishers and as a solvent. In modern science, it is primarily utilized as a laboratory reagent for cell biology, histology (tissue clearing), and organic synthesis.
Key Distinction for Customs:
It is NOT classified as a general "chemical mixture" or "industrial solvent" if declared specifically for analytical, laboratory, or biological research use. However, due to its high toxicity and ozone-depleting properties, it falls under strict environmental and chemical control regulations.
β οΈ Critical Classification Point:
- If declared as a pure chemical reagent for laboratory analysis β Chapter 29 (Organic Chemicals).
- If declared as a mixture/formulation (e.g., pre-diluted) β Chapter 38 (Miscellaneous Chemical Products).
- Must be declared with CAS number: 56-23-5.
π¦ Part II: HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Purity/State |
|---|---|---|---|
2903.41.10.00 |
Carbon Tetrachloride (Pure), not mixed with other halogenated derivatives | Lab reagent, histology clearing, analytical standard | β High Purity (>99%) |
2903.41.80.00 |
Other Halogenated Derivatives of Acyclic Hydrocarbons (if not strictly CClβ pure) | Less common; usually for impure grades or mixtures | β Impure/Mixed |
3824.99.92.00 |
Preparations not elsewhere specified or included (e.g., diluted formulations) | Pre-diluted lab solutions, specialized cleaning agents | β Formulated |
π Key Reminder:
- Pure Carbon Tetrachloride for lab use is strictly classified under 2903.41.10.00.
- Do not misdeclare as "Industrial Solvent" (e.g., 3814.00) to avoid higher scrutiny, as CClβ is heavily regulated under international environmental treaties (Montreal Protocol).
- Documentation is Key: Customs requires explicit declaration of "Laboratory Reagent" and CAS number 56-23-5.

- IEEPA 10% Surcharge: International Emergency Economic Powers Act additional tariff for China.
- Total 40.7%: This is a high-cost item. Importers must factor this into landed cost calculations.
- Environmental Note: CClβ is an ozone-depleting substance. Importers may need EPA registration or Toxic Substances Control Act (TSCA) compliance documentation.
π οΈ Part IV: Practical Customs Clearance Advice (Real-World Pitfall Avoidance Guide)
β 1. Required Documentation Checklist (Mandatory)
| Document | Must Provide | Notes |
|---|---|---|
| β Certificate of Analysis (COA) | βοΈ | Must state purity β₯99% and CAS number 56-23-5 |
| β Safety Data Sheet (SDS) | βοΈ | Section 14: Transport Information; Section 15: Regulatory Info |
| β Bill of Lading / Air Waybill | βοΈ | Correctly marked "UN 1846, Class 6.1, PG II" |
| β Commercial Invoice | βοΈ | Explicitly state "Carbon Tetrachloride, CAS 56-23-5, Lab Reagent" |
| β EPA/TSCA Compliance Certificate | βοΈ | Required for chemical imports into the US |
| β Import License (if applicable) | βοΈ | Some states/cases may require prior approval due to hazardous nature |
β 2. Declaration Best Practices (Key Mnemonic)
π₯ "Pure CClβ, Class 6.1, EPA TSCA, Label Clear!"
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Pure CClβ for Lab | 2903.41.10.00 + "Lab Reagent" |
Declare as "Solvent" β Higher scrutiny/penalty |
| Mixed/Diluted CClβ | 3824.99.92.00 |
Declare as pure β Misclassification |
| No SDS Provided | β | Will be rejected at customs |
| Missing CAS Number | β | Customs cannot verify chemical identity |
β 3. Special Handling Requirements
| Situation | Recommendation |
|---|---|
| Hazardous Material Transport | Must be shipped as UN 1846, Class 6.1 (Toxic), Packing Group II. Ensure proper packaging and labeling. |
| EPA Regulations | CClβ is restricted under the Montreal Protocol. Verify if the shipment complies with TSCA Section 5 or existing inventory rules. |
| Small Quantity Samples | Still subject to full HS classification and tariffs. Do not assume de minimis applies for hazardous chemicals. |
| Re-export from Third Country | If shipped via Singapore or Malaysia, ensure origin is still declared as China if produced there. Transshipment does not erase country of origin. |
π Part V: Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate | Certification Required | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 2903.41.10.00 |
40.7% | TSCA + EPA | High regulatory barrier |
| π¨π³ China | 2903.41.10.00 |
6.5% | None (Import) | Export-controlled; export license may be needed |
| πͺπΊ EU | 2903.41.10.00 |
6.5% | REACH Registration | Strict environmental limits |
| π¦πΊ Australia | 2903.41.10.00 |
5.0% | AICIS Compliance | Hazardous chemical registry required |
| π―π΅ Japan | 2903.41.10.00 |
1.5% | PRTR Law Notification | Environmental reporting mandatory |
π Conclusion:
- USA has the highest tariff burden (40.7%) due to trade wars and surcharges.
- EU and Japan have lower base tariffs but strict REACH/PRTR environmental compliance requirements.
- Global Trend: Increasing restrictions on CClβ imports due to ozone depletion concerns. Always verify local environmental regulations.
π Part VI: Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Declaring CClβ as "General Solvent" (HS 3814)
π Consequence: Misclassification β Fine + Delay + Possible Seizure
β Mistake 2: Omitting CAS Number 56-23-5 on Invoice
π Consequence: Customs unable to verify chemical β Hold for inspection
β Mistake 3: Not labeling as Hazardous (Class 6.1)
π Consequence: Transportation violation β Rejection by carrier + Customs penalty
β Mistake 4: Assuming De Minimis applies for small samples
π Consequence: Hazardous chemicals are excluded from de minimis in most jurisdictions (especially US)
β Correct Approach:
"Carbon Tetrachloride, CAS 56-23-5, Purity 99%, Laboratory Reagent, UN 1846, Class 6.1, PG II, For Research Use Only"
π― Part VII: Conclusion: Professional Declaration Saves Costs and Time
π― Remember the Mnemonic:
πΉ "Pure CClβ, 2903, 40.7% in US, EPA TSCA is key!"
πΉ "HS Code determines fate, tariff difference is huge, declare correctly, avoid fines!"
π Tips:
- If your CClβ is produced in Vietnam or Mexico, you may avoid IEEPA/301 surcharges, reducing total tariff to 5.7% (US).
- Always request pre-clearance rulings from customs brokers if importing large volumes.
- Ensure SDS and COA match exactly.

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
