π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π 1. Product Definition & Classification: Do You Really Understand "Antigen Antibody Reagents"?
In international trade, "Food Safety Antigen Antibody Reagents" are biological products primarily used for diagnostic or laboratory testing purposes. Their core function is to detect specific antigens or antibodies related to food safety issues (e.g., pesticide residues, veterinary drugs, pathogens).
According to the provided data, these reagents are classified into three specific HS Codes based on their material characteristics and specific application scope. It is crucial to distinguish between general immunological products and those specifically tailored for food safety or containing specific antiserum/antigen compositions.
β οΈ Key Distinction Point:
- If the product is a general immunological product (excluding monoclonal antibodies), it may fall under 3002.13.00.90.
- If the product is specifically designed for food safety detection and contains antigens or antiserum, it must be classified under 3822.19.00.10 or 3822.19.00.30.
- Misclassification can lead to significant tax discrepancies or customs delays.
π¦ 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Key Characteristics |
|---|---|---|---|
3822.19.00.10 |
Antigen-antibody reagents for food safety fields | Food safety testing, lab diagnostics | Contains antigen or antiserum; specific to food safety |
3822.19.00.30 |
Antigen-antibody reagents for food safety detection | Food safety detection, lab diagnostics | Contains antigen or antiserum; diagnostic/lab reagent scope |
3002.13.00.90 |
Antigen reagents in the field of immunology | Immunology testing, non-monoclonal | Immunological product; excludes monoclonal antibodies |
π Important Reminder:
- All reagents explicitly mentioned as "Food Safety Antigen Antibody Reagents" should primarily be evaluated under 3822.19.00.10 or 3822.19.00.30.
- The distinction between.10and.30often lies in specific material features or sub-category definitions within the food safety diagnostic scope.
-3002.13.00.90is a broader category for immunological products but does not specifically highlight "food safety" or "antiserum/antigen" material features in the same way as the 3822 codes.

π Note:
- Identical tariff structure to3822.19.00.10.
- Both codes fall under the diagnostic or laboratory reagent scope with antigen or antiserum material features.
- The key is to ensure the product documentation explicitly states "Food Safety" application to justify these codes.
π― 3. 3002.13.00.90 ββ Antigen Reagents in the Field of Immunology
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 Surtax | 0.0% |

π 6. Common Errors & Pitfall Guide (Blood and Tears Lessons)
β Error 1: Declaring "Antigen Antibody Reagents" as generic "Laboratory Chemicals"
π Consequence: Risk of misclassification, potential audits, or delays.
β Error 2: Using 3002.13.00.90 for products explicitly labeled "Food Safety"
π Consequence: Customs may question the accuracy, though the tax rate is the same. Best to use specific food safety codes.
β Error 3: Including Monoclonal Antibodies under 3002.13.00.90
π Consequence: Rejection. The data explicitly states "excluding monoclonal antibodies."
β Error 4: Not specifying "Antigen/Antiserum" content in documentation
π Consequence: Customs may classify under general diagnostic reagents with different tax rates.
β Correct Approach:
"Food Safety Diagnostic Kit: Antigen-Antibody Reagents (Antiserum), for Pesticide Residue Detection, Model XYZ, Contains Antigens"
π― 7. Conclusion: Professional Declaration, Time-Saving, Cost-Effective!
π― Remember the Mantra:
πΉ "Food Safety + Antigen/Antiserum = 3822.19 (10%)"
πΉ "General Immunology (No Mono) = 3002.13 (10%)"
πΉ "Monoclonal = Exclude from 3002.13!"
π Tips:
- Ensure all product labels and documentation explicitly mention "Food Safety" to support the use of 3822.19.00.10 or .30.

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
