π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π I. Product Definition & Classification: What is a "Carbon Tetrachloride Matrix Standard"?
A Carbon Tetrachloride Matrix Standard is a certified reference material or prepared diagnostic/laboratory reagent used primarily for calibrating analytical instruments (such as GC-MS, HPLC, or spectrometers) in chemical, environmental, and pharmaceutical testing.
It is not a raw chemical for industrial use, but a precise mixture on a backing or in a specific formulation used for quality control and calibration. In international trade, it falls under Chapter 38 (Miscellaneous Chemical Products), specifically under heading 3822 (Diagnostic or Laboratory Reagents on a Backing; Certified Reference Materials).
β οΈ Key Distinction Point:
- If the product is a Certified Reference Material (CRM) or a Prepared Diagnostic/Laboratory Reagent (whether on a backing, in kits, or in liquid/solid form for lab use), it belongs to 3822.90 or 3822.19.
- Note on Carbon Tetrachloride: Although Carbon Tetrachloride ($CCl_4$) is a controlled substance under the Montreal Protocol due to ozone depletion, small quantities used in certified reference standards for laboratory calibration are still classified under 3822, provided they are not being imported for industrial synthesis or broad commercial use. However, specific sub-headings may exist for reagents containing Carbon Tetrachloride.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
Based on the provided data, there are two primary HS Codes relevant to this product, depending on its specific form and intended use:
| HS Code | Product Description | Application Scenario | Contains Carbon Tetrachloride? |
|---|---|---|---|
3822.19.00.40 |
Diagnostic or laboratory reagents on a backing; prepared diagnostic or laboratory reagents whether or not on a backing, whether or not put up in the form of kits, other than those of heading 3006; certified reference materials: Other: Containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride | Calibration standards, lab kits for chemical analysis, certified reference materials containing $CCl_4$ | β Yes |
3822.90.00.00 |
Diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents whether or not on a backing, whether or not put up in the form of kits, other than those of heading 3006; certified reference materials: Certified reference materials | General certified reference materials (not specifically containing the controlled solvents listed above, or general CRM) | β Depends (If it does contain $CCl_4$, 3822.19.00.40 is more specific) |
π Critical Note:
- If your Carbon Tetrachloride Matrix Standard explicitly contains Carbon Tetrachloride ($CCl_4$) as part of the matrix or solvent system for calibration,3822.19.00.40is the most accurate classification according to the description: "Other: Containing... carbon tetrachloride".
- If it is a general Certified Reference Material (CRM) that does not contain methyl chloroform or carbon tetrachloride, then3822.90.00.00applies.
- Recommendation: For a product explicitly named "Carbon Tetrachloride Matrix Standard,"3822.19.00.40is likely the correct code due to the specific mention of Carbon Tetrachloride in the sub-heading description.

π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
β 1. Required Documentation Checklist (Essential)
| Document | Must Provide | Explanation |
|---|---|---|
| β Certificate of Analysis (CoA) | βοΈ | Must explicitly state the concentration of Carbon Tetrachloride and certify it as a "Reference Standard" or "Calibration Material." |
| β EPA TSCA Certification | βοΈ | CRITICAL. Since Carbon Tetrachloride is a TSCA-regulated chemical, you must prove it is for laboratory analysis/reference only, not for industrial use. |
| β Safety Data Sheet (SDS) | βοΈ | Must comply with GHS standards, highlighting flammability (if applicable) and environmental hazards. |
| β Commercial Invoice | βοΈ | Clearly describe as "Certified Reference Standard for Laboratory Calibration," NOT "Solvent" or "Chemical." |

| β Product Photos | βοΈ | Show labeling, vial type, and batch numbers. |
β 2. Declaration Tips (Key Mnemonics)
π₯ "Declare as CRM, Not Solvent; EPA Check is Must; 0% Tax but High Compliance!"
| Scenario | Correct Declaration Method | Incorrect Method |
|---|---|---|
| Lab Calibration Standard | 3822.19.00.40 - "Certified Reference Material containing Carbon Tetrachloride for Lab Calibration" |
"Carbon Tetrachloride Solvent" β High Risk of EPA Violation & Seizure |
| Kit with Reagents | 3822.19.00.40 - "Diagnostic Kit containing Carbon Tetrachloride" |
"Laboratory Chemical" (Too vague) |
| General CRM (No CCl4) | 3822.90.00.00 - "Certified Reference Material" |
Misclassifying as 3822.19.00.40 if no CCl4 is present |
β 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| EPA Regulation | Carbon Tetrachloride is banned for most commercial uses. Import for laboratory analysis is permitted but requires strict documentation proving it is a Reference Standard. |
| Quantity Limits | Small quantities for lab use are easier to clear. Large volumes may trigger EPA scrutiny for potential diversion to industrial use. |
| Misclassification Risk | If you declare it as a generic chemical, you may face Section 301 tariffs (if not reclassified correctly) and EPA penalties. Always use the specific CRM codes. |
| Origin Declaration | Even with 0% tariff, accurate origin declaration is critical for any future policy changes or trade disputes. |

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
