Potassium Iodide

🧪 Potassium Iodide (Potassium Iodide)

🌐 HS Code Classification & Customs Clearance Guide | 2026 Updated Tariff Rules | Professional Import Strategy
📌 One, Product Definition & Classification: What Exactly Is Potassium Iodide?

Potassium iodide (KI) is an inorganic salt widely used in pharmaceuticals, radiological protection, and chemical synthesis. In international trade, it is classified under inorganic compounds based on its chemical composition and intended use.

⚠️ Key Classification Rule:
- If the product is pure potassium iodide, used primarily for therapeutic or prophylactic purposes (e.g., thyroid protection during nuclear emergencies), it falls under medicinal preparations.
- If it is not formulated for medical use, but rather for industrial or chemical applications (e.g., in photography, catalysts, or lab reagents), it may be classified under inorganic salts.

✅ Critical Distinction:
- Medicinal use → HS Code: 3004.90.92.70
- Non-medicinal use → HS Code: 2827.60.20.00 (if pure) or 2827.60.51.00 (if mixed)

📦 Two, HS Code Classification Details (2026 Updated Tariff Authority)

🔍 Important Note:
- Potassium iodide alone (not in a formulation) → 2827.60.20.00
- Potassium iodide in a medicine (e.g., tablet, capsule, liquid) → 3004.90.92.70 or 3004.50.50.10
- Even if labeled "for health", if it's not in a measured dose or retail packaging, it may not qualify as a "medicament"

💰 Three, 2026 Latest Tariff Rate Breakdown (Including Additional Duties & Policies)

✅ Applicable Country: China (CN)
✅ Applicable Region: Global (for standard customs declarations)
✅ Effective Date: 2025–2026 (current tariff regime)

🎯 1. 2827.60.20.00 — Potassium Iodide (Pure, Non-Medicinal)

📌 Explanation:
- This is a pure chemical compound, not a medicine.
- No additional tariffs apply under current US-China trade policies.
- Ideal for industrial, lab, or research use.

🎯 2. 2827.60.51.00 — Other Iodides and Iodide Oxides (Other than Potassium)

📌 Note:
- Applies to mixed or impure forms of potassium iodide (e.g., technical grade, industrial grade).
- Still 0% tariff — no special trade restrictions.

🎯 3. 3004.90.92.70 — Medicaments: Preparations Affecting Electrolytic, Caloric, or Water Balance (Other)

📌 Critical Requirement:
- Must be put up in measured doses (e.g., tablets, capsules, liquid drops) or retail packaging.
- Must be for medical use (e.g., thyroid protection, iodine deficiency prevention).
- Even if pure KI, if it’s in a medicine form, this code applies.

🎯 4. 3004.50.50.10 — Medicaments: Containing Vitamins or Other Products of Heading 2936: Single Vitamins Combined with Minerals

📌 When to Use This Code:
- If potassium iodide is combined with other nutrients (e.g., vitamin C, zinc, selenium) in a daily supplement.
- Must be in measured doses (e.g., 1 tablet/day).
- Common in multivitamin tablets, thyroid support formulas, pregnancy supplements.

✅ 3. Special Cases & Handling

🌍 Five, Global Customs Comparison (2026 Updated)

📌 Conclusion:
- All major markets apply 0% tariff to potassium iodide, regardless of HS code.
- No trade war tariffs apply to this product (unlike electronics, steel, or solar panels).
- The key is correct classification, not tariff rate.

📌 Six, Common Mistakes & Risk Avoidance (Real-World Pitfalls)

❌ Mistake 1: Declaring pure KI powder as a medicine (3004.90.92.70)
👉 Risk: Customs may reject it as not a medicinal preparation → delay, refund, or reclassification

❌ Mistake 2: Using 2827.60.20.00 for KI tablets in a retail package
👉 Risk: Missing out on lower risk profile and medical exemption benefits; may be flagged for inspection

❌ Mistake 3: Not providing a CoA or SDS
👉 Risk: Entry denied or detained at port — no chemical identity proof

❌ Mistake 4: Labeling "potassium iodide" without specifying grade (e.g., "pharmaceutical grade")
👉 Risk: Customs may assume it’s industrial → stricter documentation

✅ Correct Labeling Example:

"Potassium Iodide, USP Grade, 130 mg per tablet, for Thyroid Protection, in Retail Packaging, 100 Tablets"
→ HS Code: 3004.90.92.70

🎯 Seven, Conclusion: Accurate Classification = Smooth Clearance

🎯 Remember the Golden Rule:

🔹 "If it’s pure → 2827.60.20.00
🔹 If it’s a medicine → 3004.90.92.70 or 3004.50.50.10
🔹 If it’s a supplement → 3004.50.50.10
🔹 No tariffs in any major market — but wrong code = delays & costs!

📌 Pro Tip:

If you’re exporting potassium iodide in medicinal form, consider applying for Advance Ruling (Pre-Clearance) with customs authorities (e.g., U.S. CBP, EU Customs) to lock in HS code and avoid disputes.
