📌 One Product, Two Key HS Codes – Know the Difference to Avoid Costly Mistakes!

📦 1. Product Definition & Classification: What Is Sulfamethoxazole?

Sulfamethoxazole is a synthetic sulfonamide antibiotic used in the treatment of bacterial infections (e.g., urinary tract infections, bronchitis, and some types of pneumonia). It is often combined with trimethoprim (as co-trimoxazole) for synergistic effect.

In international trade, Sulfamethoxazole is classified under two distinct HS Codes, depending on its form and packaging:

⚠️ Critical Distinction:
- If it's bulk powder or raw API → Use 2935.90.48.00
- If it's in tablets, capsules, or mixed with other drugs → Use 3004.90.92.13

📌 Important Note:
- 3004.20.00.75 is invalid for Sulfamethoxazole — it’s likely misclassified or outdated.
- Never use this code — it will trigger customs delays, audits, or penalties.

❌ Mistake 1: Using 3004.20.00.75 (Failed to retrieve tax)
👉 Result: Customs delays, audit, or rejection
👉 Fix: Never use this code — it’s invalid or outdated.

❌ Mistake 2: Declaring tablets as "chemical raw material"
👉 Result: Pay 6.5% duty instead of 0% → Waste of money

❌ Mistake 3: Not providing CoA or GMP certificate
👉 Result: Customs holds shipment → Delivery delay + storage fees

❌ Mistake 4: Using "Sulfonamide" as general term
👉 Result: Misclassification → Penalties or seizure

✅ Correct Declaration Example:

"Sulfamethoxazole Tablets, 500mg, 100 count, in blister pack, for therapeutic use, manufactured under GMP, CoA available"

🎯 7. Final Verdict: Maximize Savings, Minimize Risk

✅ Use 2935.90.48.00 only for raw API → 6.5% duty
✅ Use 3004.90.92.13 for tablets/capsules → 0% duty
