🐷 Pig Thyroid Extract (Porcine Thyroid Extract)

🌐 HS Code & Tariff Guide | 2026 Updated Customs Classification | Professional Import Strategy
📌 One Product, Multiple Classifications – Why the Same Item Has Different Tariffs?

The pig thyroid extract is a biologically active substance derived from porcine (pig) thyroid glands. Despite being the same product, it can be classified under two different HS Codes, leading to dramatically different tariffs depending on how it's described, its form, and its intended use.

This guide breaks down why it's classified under two HS Codes, explains each tax component in detail, and provides clear customs clearance recommendations to avoid costly errors.

📦 1. HS Code Classification Breakdown (2026 Tax Authority Reference)

⚠️ Critical Insight:
The same physical product can fall into two different categories based on how it's processed, labeled, and declared.
- If it’s raw or minimally processed → 3001.20.00.00
- If it’s treated as a protein derivative → 3504.00.10.00

💰 2. Detailed Tariff Breakdown (U.S. Import Rules – Effective Nov 10, 2025)

🎯 HS Code 3001.20.00.00 – Thyroid Extract (Gland & Extract Category)

✅ When This Applies:
- Raw or crude thyroid extract from pig glands
- Used in nutraceuticals, animal feed, or research
- Not chemically altered or classified as a protein derivative

🎯 HS Code 3504.00.10.00 – Animal Protein Substance & Derivatives

✅ When This Applies:
- Extract is purified, concentrated, or processed into protein form
- Marketed as biological reagent, enzyme, or pharmaceutical intermediate
- Used in biotech labs, drug development, or specialty formulations

🔍 Why the Higher Tax?
- The U.S. Customs and Border Protection (CBP) considers this a "protein derivative" if it has been modified beyond basic extraction.
- Even minor processing steps (e.g., lyophilization, filtration, pH adjustment) can trigger this classification.

🌍 4. Global Market Comparison (2026 Update)

📌 Key Takeaway:
- The U.S. is the only market with IEEPA and Section 301 tariffs on this product
- China-origin products face 10% IEEPA regardless of HS Code
- Non-China origin may avoid IEEPA — consider shifting supply chain

📌 5. Common Mistakes & Real-World Pitfalls

❌ Mistake 1: Declaring crude thyroid extract as "protein derivative"
👉 Result: Pay 22.5% instead of 10% → extra 12.5% cost

❌ Mistake 2: Not disclosing processing steps on invoice
👉 Result: CBP reclassifies as 3504.00.10.00 → back taxes + penalties

❌ Mistake 3: Using generic name like "Thyroid Extract" without clarification
👉 Result: Customs assumes it’s a protein derivative → higher tariff

❌ Mistake 4: Shipping from China without IEEPA exemption
👉 Result: 10% IEEPA tariff applied automatically — no escape

✅ Correct Declaration Example:

"Porcine Thyroid Extract, crude, non-protein derivative, extracted via cold-press method, not enzymatically modified, for research use, Origin: Vietnam"

🎯 6. Final Verdict: How to Optimize Your Import Cost

🔹 If your product is raw or minimally processed → Use 3001.20.00.00 → 10% total
🔹 If it’s purified, concentrated, or treated as a protein → Use 3504.00.10.00 → 22.5% total
🔹 If from China → 10% IEEPA applies to both
🔹 If from non-China country → Consider IEEPA exemption → 0% on 122 tariff

📣 Immediate Action Steps

📞 Contact a U.S. Customs Broker + Request an HS Code Pre-Ruling (Advance Ruling)
📊 Submit product specs, process flow, CoA, and origin proof
✅ Lock in the correct HS Code and tariff before shipment

✨ Pro Tip:

If you’re sourcing from Vietnam, Mexico, or the EU, you can avoid the 10% IEEPA tariff — even if the product is identical.
Reconsider your supply chain — it could save you thousands per shipment.

🎯 Conclusion: Precision in Classification = Profit in Trade

📌 Remember:
- Raw extract = 10%
- Protein derivative = 22.5%
- China origin = 10% IEEPA (on top of either)
- Labeling matters more than you think

💼 Your next shipment could be 12.5% cheaper — if you classify it right.
🚀 Don’t let a mislabeled invoice cost you thousands.
🔍 Get your HS Code right — before the truck even leaves the port.
