🐟 Fish Oil Capsules: HS Code Classification & US Customs Clearance Guide (2026)

🌐 HS Code Reference & Customs Strategy | 2026 Tariff Analysis | Professional Clearance Guidelines
📌 I. Product Definition & Classification: What is "Fish Oil"?

Fish Oil, typically sold in capsule form, is a dietary supplement derived from the tissues of oily fish. In international trade, its classification depends heavily on its physical form and intended use:

1. Pure Fish Oil (Liquid/Oil Form):
Defined as fish oils and their fractions, whether or not refined. It falls under the general chapter of animal fats and oils.

2. Dietary Supplements/Capsules:
Defined as preparations in the form of capsules, tablets, or liquids intended to supplement the diet. This category often falls under food preparations or pharmaceutical products, depending on the specific formulation and regulatory status.

⚠️ Key Distinction Point:
- If declared as pure oil/fat regardless of packaging → Classified under Chapter 15.
- If declared as a finished drug/supplement with specific health claims → Classified under Chapter 30 or Chapter 21.

📦 II. HS Code Classification Details (2026 Latest Tariff Concordance)

🔍 Critical Reminder:
- 1504.10.40.00 focuses on the raw material nature (Fish Oil).
- 3004.90.92.70 focuses on the pharmaceutical/therapeutic nature (Capsule Form).
- 2106.90.99.73 focuses on the general food supplement nature (Other Food Prep).
- Note: The choice significantly impacts the tax rate due to Section 301 and IEEPA tariffs.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Taxes)

✅ Applicable Country: USA (US)
✅ Origin: China (CN)
✅ Effective Time: From November 10, 2025 (including subsequent imports)

🎯 1. 1504.10.40.00 —— Fish Oils and Their Fractions

📌 Explanation:
- The 25% Section 301 tariff applies to most Chinese-origin animal fats/oils.
- The 10% IEEPA tariff is an additional levy on Chinese goods.
- Total 37.5% is a high tariff burden. This classification treats the product essentially as a raw agricultural/animal product.

🎯 2. 3004.90.92.70 —— Medicaments (Capsule Form)

📌 Note:
- Base Tariff is 0%, which is a significant advantage.
- Only the 10% IEEPA tariff applies.
- This classification leverages the "Pharmaceutical/Medicament" exemption from Section 301 (25%), but still attracts the IEEPA 10% tariff.
- Strategy: If the product can be legally defined as a "medicament" (regulated supplement), this offers the lowest total tax rate (10%).

🎯 3. 2106.90.99.73 —— Food Preparations (Other)

📌 Note:
- This classification treats it as a general food supplement.
- It avoids the 25% Section 301 tariff (unlike 1504).
- It has a higher base rate (6.4%) than the medicament class.
- Total 16.4% is a middle-ground option. It is cheaper than pure oil (37.5%) but more expensive than medicaments (10%).

🛠️ IV. Customs Clearance Practical Advice (Risk Avoidance Guide)

✅ 1. Required Documentation Checklist (Mandatory)

✅ 2. Declaration Strategy (Key Mantra)

🔥 "Declare Form, Not Just Material! Capsule = Supplement/Med, Not Just Oil!"

✅ 3. Special Case Handling

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- USA is the most challenging market due to IEEPA and Section 301 tariffs.
- China-origin Fish Oil Capsules should NEVER be declared as Raw Oil (1504) if they can be legally classified as Supplements (3004 or 2106). The tax savings are significant (27.5% difference).

📌 VI. Common Errors & Pitfalls (Lessons Learned)

❌ Error 1: Declaring "Fish Oil Capsules" as 1504.10.40.00 (Raw Oil)
👉 Result: Pay 37.5% tax instead of 10% or 16.4%. Overpayment!

❌ Error 2: Using generic description "Fish Oil" without specifying "Capsule" or "Supplement"
👉 Result: Customs may default to the highest applicable category or request clarification, causing delays.

❌ Error 3: Assuming "De Minimis" (Section 321) applies to IEEPA tariffs
👉 Result: Incorrect. IEEPA tariffs apply even to small shipments. No exemption.

❌ Error 4: Misclassifying a therapeutic drug as a general supplement (2106) to avoid scrutiny
👉 Result: FDA compliance issues, potential seizure, and legal penalties.

✅ Correct Practice:

"Dietary Supplement, Fish Oil, Omega-3, 1000mg per Capsule, 60 Capsules, FDA Registered Facility, Model XYZ"

🎯 VII. Conclusion: Precise Classification, Cost Optimization!

🎯 Remember the Mantra:

🔹 "Capsule = Supplement/Med, Not Raw Oil!"
🔹 "10% vs 37.5%: Classification Saves 27.5%!"
🔹 "No De Minimis for IEEPA: Pay Your Taxes!"

📌 Pro Tip:
If your product has FDA Drug Approval, always use 3004.90.92.70.
If it is a General Supplement, use 2106.90.99.73 (safer) or 3004 (if compliant).
Avoid 1504 for capsules unless you are importing bulk oil in softgels without supplement claims.
