💎 Molybdenum Oxides & Hydroxides (Molybdate Mixtures)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 1. Product Definition & Classification: Do You Really Understand "Molybdate Mixtures"?
In international trade, "Molybdate Mixtures" or "Molybdenum Oxides/Hydroxides" are critical chemical raw materials used in steel alloys, lubricants, catalysts, and pigments. However, their classification depends strictly on chemical composition and purity. They fall under Chapter 28 (Inorganic Chemicals), specifically heading 2825.
Key Distinctions: * Pure Molybdenum Oxides/Hydroxides (Subheading 2825.70): Specific chemical entities like Molybdenum trioxide (MoO₃) or specific hydroxides. These are considered "specific inorganic bases/oxides." * Other Molybdenum Compounds/Mixtures (Subheading 2825.90): If the product is not strictly defined as MoO₃/hydroxide under 2825.70, or if it is a complex mixture not covered by other specific subheadings in 2825, it falls into the "Other" category.
⚠️ Critical Classification Point:
- If the product is explicitly Molybdenum oxides and hydroxides (e.g., pure MoO₃ powder) → Classify under 2825.70.00.00.
- If the product is a general mixture or does not fit the specific description of 2825.70 (or is considered "Other" under 2825) → Classify under 2825.90.90.00.
📦 2. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Applicable Scenario | Tax Rate (US/CN) |
|---|---|---|---|
2825.70.00.00 |
Molybdenum oxides and hydroxides | Pure Molybdenum Trioxide (MoO₃), specific hydroxides; used as catalysts or steel additives. | 0.0% |
2825.90.90.00 |
Other inorganic bases; other metal oxides, hydroxides, peroxides; Other: Other | Molybdate mixtures not strictly defined as oxides/hydroxides under 2825.70; complex inorganic salts; generic "molybdate mixtures." | 28.7% |
🔍 Key Reminder:
- 2825.70.00.00 is for specific molybdenum oxides/hydroxides. The tariff is 0%.
- 2825.90.90.00 is the residual category. If your "molybdate mixture" is not explicitly MoO₃/hydroxide, or if it's a blend that doesn't fit 2825.70, it lands here with a 28.7% tariff.
- Do not misclassify a generic mixture as 2825.70 to avoid audit penalties.

🛠️ 4. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Required Documentation Checklist (Non-negotiable)
| Document | Mandatory | Explanation |
|---|---|---|
| ✅ Certificate of Analysis (COA) | ✔️ | Must specify exact chemical composition (e.g., % MoO₃, % impurities). Crucial for proving 2825.70 eligibility. |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | For safe handling and hazard classification. |
| ✅ Product Specification Sheet | ✔️ | Detailed description: Physical state (powder/granules), purity, CAS number. |
| ✅ Commercial Invoice | ✔️ | Must clearly state: "Molybdenum Oxide (MoO₃)" or "Molybdate Mixture" and HS Code. |
| ✅ Packing List | ✔️ | Net/Gross weight, package dimensions. |
| ✅ Origin Certificate | ✔️ | If claiming any preferential treatment (though 2825.70 is 0% regardless). |
✅ 2. Classification Strategy (Key Mantra)
🔥 "Pure Oxide = 0%, Mixture = 28.7%! Define Clearly or Pay High!"
| Scenario | Correct HS Code | Wrong Action |
|---|---|---|
| Pure MoO₃ (>99% purity) | 2825.70.00.00 |
Classify as "Other" → 28.7% |
| Molybdenum Dioxide (MoO₂) | 2825.70.00.00 |
Misclassify as 2825.90 → 28.7% |
| Complex Molybdate Salt Mixture | 2825.90.90.00 |
Force classify as 2825.70 → Audited & Penalized |
| Ammonium Molybdate | 2825.90.90.00 (typically) |
Do not assume it's 2825.70 unless it's specifically hydroxide/oxide. |
📌 Note on Ammonium Molybdate:
- Ammonium molybdate is often classified under 2825.90.90.00 ("Other inorganic bases") because it is a salt, not a pure oxide/hydroxide. Check specific rulings for your exact compound.
✅ 3. Special Circumstances
| Situation | Handling Advice |
|---|---|
| High Purity MoO₃ | Provide COA showing >99% MoO₃ content to justify 2825.70.00.00. |
| Mixture with Other Metals | If it contains significant amounts of other metals (e.g., Tungsten), re-evaluate classification. |
| Chemical Control Compliance | Ensure compliance with EPA/TSCA regulations. Some molybdate compounds may require EPA notifications. |
| Bulk vs. Retail | Bulk shipments require more detailed chemical declarations. |

📌 6. Common Mistakes & Pitfalls (Blood & Tears Lessons)
❌ Mistake 1: Calling "Ammonium Molybdate" Molybdenum Oxide
👉 Consequence: Classified under 2825.90 → 28.7% tariff instead of potentially lower (if eligible) or correct classification.
❌ Mistake 2: Ignoring Purity Levels
👉 Consequence: Low-purity molybdenum mixtures may not qualify as "Oxides" under 2825.70, leading to 28.7% tariff.
❌ Mistake 3: Incomplete Chemical Description on Invoice
👉 Consequence: Customs may reclassify to 2825.90.90.00 by default → 28.7% tariff.
❌ Mistake 4: Assuming All Molybdenum Compounds are 2825.70
👉 Consequence: Salts (e.g., Sodium Molybdate) are NOT oxides/hydroxides. They go to 2825.90.90.00 → 28.7% tariff.
✅ Correct Practice:
"Molybdenum Trioxide (MoO₃), >99% Purity, White Powder, CAS No. 1313-27-5, For Steel Alloying, COA Attached"
🎯 7. Conclusion: Precision Classification Saves Money!
🎯 Remember the Mantra:
🔹 "Pure Oxide = 0%, Mixture/Salt = 28.7%! Check COA!"
🔹 "HS Code 2825.70 is Gold for MoO₃, 2825.90 is Pit for Mixtures!"
📌 Pro Tip:
- If your product is Ammonium Molybdate or Sodium Molybdate, verify if it can be classified under 2825.90.90.00 or if there are other headings (e.g., 3102 for fertilizers, though rare for molybdenum).
- Always request a Pre-Ruling from CBP if your product is a complex mixture. The 25.7% tariff difference is too large to ignore.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
