📌 Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring as “Chemical Reagent” when used in medical diagnostics
👉 Consequence: 35–40% duty instead of 10% → overpayment + audit risk

❌ Mistake 2: Not providing Certificate of Analysis (COA)
👉 Consequence: Customs may misclassify → delays, penalties, or return

❌ Mistake 3: Using vague terms like “Liquid for Lab Use”
👉 Consequence: Customs may assign generic HS Code → higher duty

❌ Mistake 4: Failing to distinguish between medical vs. general chemical use
👉 Consequence: Wrong HS Code → 10% vs. 35–40% difference

✅ Best Practice:

“Endotoxin-Free Liquid, Certified, <0.25 EU/mL, for In Vitro Diagnostic Use, Batch XYZ, COA Attached”

🎯 Conclusion: Precision Classification Saves Money!

🎯 Remember the Rule:

🔹 “Medical Use = 10%, General = 35–40%”
🔹 “HS Code Determines Duty, Duty Determines Profit!”
🔹 “Provide Proof, Get Relief!”

📌 Pro Tip:
If your product is used in cell culture, diagnostics, or pharmaceutical manufacturing, ensure it’s clearly labeled and documented to qualify for 10% duty instead of 35–40%.
Consider applying for an Advance Ruling from CBP to lock in classification before shipment.
