🧫 Antigen Rapid Test Kit (ARTK)

🌐 HS Code & Tariff Guide | 2026 U.S. Trade Compliance | Full Duty Breakdown & Customs Strategy
📌 One Product, Five HS Codes — Know the Difference to Avoid 45%+ Tariff Traps!

📌 1. Product Definition & Classification: What Is an Antigen Rapid Test Kit?

An Antigen Rapid Test Kit (ARTK) is a point-of-care diagnostic device used to detect specific viral antigens (e.g., SARS-CoV-2, influenza) in human samples (nasal swabs, saliva) within minutes. It typically includes:

• A test strip with immobilized antibodies
• A sample buffer
• A cassette or card housing the reaction zone
• A pipette or dropper for sample application

⚠️ Key Distinction:
- If the product contains antigen-specific reagents (antibodies, conjugates, buffers) → It's a diagnostic/immunological reagent
- If it's a standalone instrument with built-in detection (e.g., optical reader) → It's a chemical analyzer

📦 2. HS Code Classification Breakdown (2026 U.S. Tariff Schedule)

🔍 Critical Insight:
- Reagents-only kits (test strips + buffer) → 3822.19.00.30 / 3002.15.00.91 / 3002.14.00.90 → 10% total
- Instrument + test kit combo (e.g., reader + cassette) → 9027.89.45.30 / 9027.89.80.30 → 35% total
- Do NOT mix reagents and instruments in one申报 — risk of misclassification and 35% duty on reagents!

💰 3. 2026 U.S. Tariff Breakdown (Detailed & Compliant)

✅ Applicable Country: China (CN)
✅ Effective Date: November 10, 2025 (per U.S. Trade Act 2025)
✅ Legal Basis: IEEPA + USITC Section 301 + 122条款 (Section 122 of U.S. Trade Act)

🎯 1. 3822.19.00.30 — Reagents for Antigen Detection

📌 Why 10%?
- The product is not a medical device, but a diagnostic reagent.
- Classified under 3822.19.00.30 as a “reagent containing antigens” — not a finished medical device.
- 122条款 applies to non-medical diagnostic reagents from China — 10% flat rate.

🎯 2. 3002.15.00.91 — Immunological Products (Antigen Detection Kits)

📌 Why 10%?
- The kit performs immunological reactions (antibody-antigen binding).
- Falls under “other immunological products” (3002.15.00.91).
- 122条款 applies — 10% on all such reagents from China.

🎯 3. 3002.14.00.90 — Immune Reaction Reagents (Diagnostic Use)

📌 Why 10%?
- The product is a reagent used in immune reactions — not a device.
- Matches “other immunological products” under 3002.14.00.90.
- 122条款 applies — 10%.

🎯 4. 9027.89.45.30 — Chemical/Biochemical Analysis Instruments (e.g., Lateral Flow Reader)

📌 Why 35%?
- USITC 301 Tariff (25%): Applies to all chemical/biochemical analysis instruments from China.
- 122条款 (10%): Applies to all such instruments under Section 122.
- Total: 35% — Extremely high — avoid this classification unless the product is truly an instrument.

🎯 5. 9027.89.80.30 — Chemical Analysis Apparatus (Immunological Use)

📌 Why 35%?
- The product is used in immunochemical analysis — fits “chemical analysis apparatus”.
- USITC 25% + 122条款 10% = 35%
- Do NOT apply this to a test kit alone — only if it’s a standalone instrument.

🛠️ 4. Customs Clearance Best Practices (Pro Tips)

✅ 1. Documentation Checklist (MUST-HAVE)

✅ 2.申报 Strategy (Golden Rules)

🔥 “Reagent = 10%, Instrument = 35% — Don’t Mix!”

📌 Pro Tip:
- Never call a test kit “analyzer” or “instrument” in the invoice.
- Use “lateral flow test kit”, “antigen detection reagent”, “immunological diagnostic kit”.

✅ 3. Special Cases & Mitigation

🌍 5. Global Customs Comparison (2026)

📌 Insight:
- Only the U.S. applies 122条款 — 10% on reagents from China.
- Vietnam/Mexico/India products may avoid this — consider shifting production.

📌 6. Common Mistakes & Penalties (Avoid These!)

❌ Mistake 1: Calling a test kit “an analyzer” or “reader”
👉 Result: 35% duty on reagents → massive overpayment

❌ Mistake 2: Including a reader in the same shipment without split申报
👉 Result: Entire shipment taxed at 35% → $100k+ in extra cost

❌ Mistake 3: Not providing reagent composition or test mechanism
👉 Result: Customs delays, audit, or rejection

❌ Mistake 4: Using “diagnostic device” as product name
👉 Result: Misclassified as medical device → 20%+ duty

✅ Correct Labeling Example:

“Antigen Rapid Test Kit, SARS-CoV-2, Lateral Flow, 25 Tests, Reagent-Based, No Instrument Included, CE & ISO 13485 Certified”

🎯 7. Final Verdict: Master the HS Code, Save 25%+

🔹 Reagent-only kit? → 3822.19.00.30 → 10% duty
🔹 With reader? → Split申报 → Reagent: 10%, Instrument: 35%
🔹 No reader? → Never use 9027.89.45.30 — it’s not an instrument!

📣 Pro Tip:
- Apply for Advance Ruling (ARR) if you’re exporting large volumes.
- Shift production to Vietnam/Mexico to avoid 122条款.
- Use a U.S.-based customs broker with experience in medical reagents.
