📌 One Product, One Code, Zero Guesswork — Precision Customs for Chemicals

📌 一、Product Definition & Classification: What Is Sodium Perborate Tetrahydrate?

Sodium perborate tetrahydrate is a white, crystalline, water-soluble compound used primarily as a bleaching agent, disinfectant, and oxygen-releasing oxidizer in household detergents, laundry products, and industrial cleaning formulations. It belongs to the peroxoborates (perborates) family — a class of inorganic peroxides derived from boric acid and hydrogen peroxide.

⚠️ Key Legal Distinction:
- Sodium perborate (especially the tetrahydrate form) is not a simple borate; it contains peroxide linkages (O–O bonds), making it a chemical oxidizer. - This triggers specific tariff treatment under HS Code 2840.30.00.10, not general borates or salts.

📦 二、HS Code Classification Breakdown (2026 Official Tariff Schedule)

🔍 Critical Rule:
- Only 2840.30.00.10 applies to sodium perborate tetrahydrate — even if sold in powder, granular, or liquid form. - Do not use 2840.30.00.50 unless it’s a different metal perborate (e.g., potassium perborate).

💰 三、2026 Tariff & Tax Breakdown (Detailed & Compliant)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: January 1, 2025 (updated tariff schedule)

🎯 1. 2840.30.00.10 — Sodium Perborate Tetrahydrate

📌 Why No Duty?
- Despite being a peroxide compound, sodium perborate tetrahydrate is not currently subject to the 25% USITC 301 tariffs on chemicals from China. - It is not listed in the Section 301 List 3 or Section 321 List of restricted chemicals. - The U.S. Customs and Border Protection (CBP) has confirmed zero duty for this code under current rulings.

🎯 2. 2840.30.00.50 — Other Peroxoborates (Not Applicable)

⚠️ Warning:
- If you incorrectly classify sodium perborate as 2840.30.00.50, you risk: - Customs audit for misclassification - Penalties for incorrect valuation - Delayed clearance due to inconsistent documentation

🛠️ 四、Customs Clearance Best Practices (Pro Tips)

✅ 1. Required Documentation (Must-Have List)

✅ 2.申报技巧（Key Rules to Remember）

🔥 “Sodium = 2840.30.00.10, Not 50! Perborate = Peroxide, Not Salt!”

✅ 3. Special Handling & Risk Mitigation

🌍 五、Global Customs Comparison (2026)

📌 Insight:
- Only the U.S. has a complex tariff landscape, but sodium perborate tetrahydrate is currently duty-free. - All other major markets treat it as non-hazardous for customs purposes.

📌 六、Common Mistakes & Pitfalls (Avoid These!)

❌ Mistake 1: Classifying sodium perborate as 2840.30.00.50
👉 Result: Audit, penalties, delayed shipment

❌ Mistake 2: Not labeling as "Peroxide" or omitting UN3127
👉 Result: Seizure at port, safety violation

❌ Mistake 3: Using generic name like "Borax" or "Borate"
👉 Result: Misclassification → duty underpayment risk

❌ Mistake 4: Not providing SDS or CoA
👉 Result: CBP holds shipment until documentation is submitted

✅ Correct Labeling Example:

"Sodium perborate tetrahydrate, 2840.30.00.10, UN3127, Class 5.1, Peroxide, 95% purity, 25kg drum"

🎯 七、Conclusion: Precision Pays Off

🎯 Remember the Golden Rule:

🔹 "Sodium perborate = 2840.30.00.10, Not 50!"
🔹 "Peroxide = Peroxide, Not Salt!"
🔹 "No duty in the U.S. — But document everything!"

📌 Pro Tip:

✅ Apply for a Binding Tariff Classification Ruling (BTCR) if importing > $100,000/year — locks in 0% duty and prevents future disputes.
