𧬠Diagnostic Reagents & Laboratory Kits (USzymes without Pancreatic Extract)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π Part I: Product Definition & Classification: What are "USzymes"?
"USzymes without pancreatic extract" refers to Diagnostic or laboratory reagents that are prepared on a backing, or put up in kits, but explicitly exclude those containing pancreatic enzymes (such as trypsin or pancreatin) and those classified under Heading 3006 (e.g., blood grouping reagents, pregnancy test kits).
In international trade, these are primarily used for: * In vitro diagnostics (IVD): Such as immunoassays, enzyme-linked immunosorbent assays (ELISA), or other biochemical tests. * Laboratory research: Reagents mounted on strips, cards, or kits for specific chemical or biological detection.
β οΈ Key Distinction:
- If the product contains methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride β It falls under 3822.19.00.40.
- If the product does not contain the above solvents but is still a diagnostic/reagent backing or kit (excluding Heading 3006) β It falls under 3822.19.00.80.
π¦ Part II: HS Code Classification Details (2026 Official Tariff)
| HS Code | Product Description | Applicable Scenario | Solvent Content |
|---|---|---|---|
3822.19.00.40 |
Diagnostic/Laboratory Reagents on Backing or Kits: Containing Methyl Chloroform or Carbon Tetrachloride | Reagents prepared with specific chlorinated solvents (often for cleaning or as part of the reaction medium) | β Yes |
3822.19.00.80 |
Diagnostic/Laboratory Reagents on Backing or Kits: Other | Standard diagnostic strips, test cards, or kits not containing the above chlorinated solvents | β No |
π Important Note:
- Both codes fall under Heading 3822: 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.
- Exclude Heading 3006: Do not classify blood grouping, pregnancy tests, or fertility test kits here; those belong to 3006.

π οΈ Part IV: Customs Clearance Practical Advice (Risk Avoidance Guide)
β 1. Documentation Checklist (Essential for Smooth Clearance)
| Document | Required | Notes |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must clearly state: "Diagnostic Reagent," "On Backing," or "Kit." Must specify absence of pancreatic extract if required by buyer. |
| β Composition Analysis | βοΈ | List all active ingredients. Must explicitly state whether methyl chloroform or carbon tetrachloride is present. |
| β Commercial Invoice | βοΈ | Description must match HS Code: e.g., "Diagnostic Reagent Kits, Not Containing Pancreatic Extract, Not Classified in 3006." |
| β Certificate of Origin | βοΈ | To prove origin and apply for 0% tariff. |
| β Safety Data Sheet (SDS) | βοΈ | Critical if containing chemicals (especially for 3822.19.00.40). Must comply with OSHA/GHS standards. |
| β FDA Prior Notice (if applicable) | βοΈ | If classified as a medical device or drug-related reagent, FDA registration may be required. |
β 2. Declaration Tips (Key Mnemonics)
π₯ "No Pancreas, No 3006, Check Solvents, 0% Duty!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Standard Diagnostic Kit | 3822.19.00.80 β "Diagnostic Reagent Kit, No Pancreatic Extract" |
Misclassifying as 3006 (Medical Device) β Higher scrutiny |
| Reagent with Chlorinated Solvent | 3822.19.00.40 β "Diagnostic Reagent, Contains Methyl Chloroform" |
Omitting solvent info β Customs delay or seizure |
| Pancreatic Enzyme Kit | NOT 3822 β Likely 3006 or 2937 | Using 3822 for pancreatic products β Incorrect Classification |
| Certified Reference Material | 3822.90 (Other) |
Using 3822.19 for CRM β Wrong subheading |
β 3. Special Cases & Handling
| Situation | Handling Advice |
|---|---|
| Contains Methyl Chloroform | Ensure SDS is provided. Some states/countries have environmental restrictions. Verify US EPA compliance. |
| Contains Carbon Tetrachloride | Highly Regulated. Verify if import is allowed under Montreal Protocol amendments. Ensure proper licensing if required. |
| Pancreatic Extract Present | Re-classify! If pancreatic extract is used, it may fall under Heading 3006 (if for diagnostics) or Heading 2937 (hormonal preparations). Do NOT use 3822. |
| Heading 3006 Items | If itβs a pregnancy test, HIV test, or blood grouping reagent, it belongs to 3006, not 3822. Check Chapter 30 notes. |
| Raw Reagents (Not on Backing) | If not on a backing or in a kit, it may fall under Chapter 29 (Chemical Products) or Chapter 30 (Pharmaceuticals). |
π Part V: Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 3822.19.00.40 / .80 |
0.0% | FDA (if medical), OSHA/GHS | Zero duty for Chinese origin |
| π¨π³ China | 3822.19.00 |
~0%~5% | CCC (if applicable) | Generally low tariff |
| πͺπΊ EU | 3822.00 |
0%~2.5% | CE, REACH | REACH registration may be needed for chemicals |
| π¬π§ UK | 3822.00 |
0%~2.5% | UKCA, REACH-UK | Post-Brexit rules apply |
| π―π΅ Japan | 3822.00 |
0%~5% | PSE (if electrical component) | Check FSC law for chemicals |
π Conclusion:
- The USA offers 0% duty for these reagents, regardless of origin (including China).
- The EU and Japan also offer low to zero tariffs.
- Key Risk: Not the duty, but regulatory compliance (FDA, REACH, EPA) for chemical and medical reagents.
π Part VI: Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Classifying pregnancy tests or HIV kits under 3822.19.00.80
π Consequence: These belong to Heading 3006. Misclassification leads to higher scrutiny, delays, and potential penalties.
β Mistake 2: Failing to declare methyl chloroform or carbon tetrachloride
π Consequence: Customs may detain the shipment for environmental/chemical safety review. SDS is mandatory.
β Mistake 3: Including pancreatic extracts in a "3822" declaration
π Consequence: Incorrect classification. Pancreatic enzymes may fall under 2937 (hormonal/chemical) or 3006 (diagnostic). This leads to wrong duty rates and legal issues.
β Mistake 4: Assuming all diagnostic reagents are medical devices
π Consequence: Some reagents are laboratory chemicals (Chapter 38), not medical devices (Chapter 90 or 30). Check FDA classification.
β Correct Practice:
"Diagnostic Reagent Kit, Mounted on Card, Containing Enzyme Substrates, NO Pancreatic Extract, NO Methyl Chloroform β For Laboratory Use Only"
π― Part VII: Conclusion: Professional Declaration, Save Time & Money!
π― Remember the Mnemonic:
πΉ "No Pancreas, No 3006, Check Solvents, 0% Duty!"
πΉ "SDS for Solvents, FDA for Medical, 3822 for Labs!"
π Pro Tip:
- If your reagents do not contain pancreatic extract and do not fall under Heading 3006, you are likely in Chapter 38.
- Verify if any chlorinated solvents are present to distinguish between .40 and .80.
- Both codes enjoy 0% US duty, making them competitive for import.
- Always consult with a customs broker or legal expert to confirm FDA/EPA requirements for specific chemical compositions.
π£ Immediate Action:
π Contact a licensed customs broker.
π Provide detailed product composition and SDS.
π Ensure accurate HS Code declaration to avoid delays and penalties.

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
