📦 2026 HS Code Breakdown (U.S. Tariff Schedule – China-Origin Products)

🔍 Why So Many Options?
The product sits at the intersection of diagnostics, chemistry, and biotechnology.
The correct code depends on how you declare it – is it a chemical reagent, biological product, or analytical device?

💰 2026 U.S. Tariff Detail (China-Origin Goods – Effective Nov 10, 2025)

🎯 1. 9027.89.80.30 – Chemical/Immunoanalysis Device (35.0% Total Duty)

📌 Why This Code Applies:
- The card is not just a reagent – it’s a functional analytical device that performs immune reactions and generates results.
- Matches the "chemical analysis" logic in 9027.89.80.

🎯 2. 3822.19.00.30 – Chemicals Containing Antigen (10.0% Total Duty)

📌 Why This Code Applies:
- "Antigen" is explicitly in the product name → key feature.
- Classified under "chemicals containing antigen" – a high-priority category for diagnostics.

🎯 3. 3002.15.00.91 – Immunological Preparations (10.0% Total Duty)

📌 Why This Code Applies:
- The card is based on immunological principles (antigen-antibody binding).
- Falls under "immunological preparations" – a key category for diagnostic kits.

🎯 4. 3002.14.00.90 – Biologicals for Diagnosis (10.0% Total Duty)

📌 Why This Code Applies:
- The product is biological in nature, used for diagnostic purposes.
- Matches "biologicals for diagnosis" – a common classification for rapid antigen tests.

🎯 5. 9027.89.45.30 – Analytical Instruments (35.0% Total Duty)

📌 Why This Code Applies:
- The card is used for chemical/biochemical analysis.
- Its form and function align with analytical devices used in labs.

🌍 Global Market Comparison (2026)

📌 Key Insight:
Only the U.S. imposes 10%+ IEEPA tariffs on antigen-based diagnostics.
China-origin products are hit hardest – 35% is possible.

📌 Common Mistakes & Real-World Consequences

❌ Mistake 1: Using 9027.89.80.30 for a reagent-only card
👉 Result: 35% duty instead of 10% → $25,000+ overpayment on a $100K shipment

❌ Mistake 2: Calling it “test strip” or “diagnostic kit” without mentioning “antigen”
👉 Result: Customs may reclassify as higher-duty item

❌ Mistake 3: Splitting shipment into “card” + “buffer” + “cassette”
👉 Result: Each item taxed at 89.5% → total tax > 268%

✅ Correct Way:

“Antigen Complex Detection Card – Immunological Reagent for Rapid Diagnostic Testing, Contains Antigen, CE & FDA-Registered”

🎯 Final Verdict: Choose Wisely, Save Big

🔹 Best HS Code for Cost Efficiency (U.S.):
✅ 3822.19.00.30 or 3002.14.00.90 → only 10% duty
