🌋 Aluminum Calcium Phosphate Ore (Phosphate Rock Varieties)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 Part 1: Product Definition & Classification: What Exactly is "Aluminum Calcium Phosphate Ore"?
"Aluminum Calcium Phosphate" is not a standard, single mineral species in geological taxonomy. In international trade, this term typically refers to Phosphate Rocks (Mineral Phosphates) that contain significant impurities or specific mineral compositions including Aluminum (Al) and Calcium (Ca) alongside the primary phosphate mineral (usually apatite).
It is crucial to distinguish between: 1. Raw Phosphate Rock: Naturally occurring mineral phosphate rock, whether or not it has been crushed, ground, or beneficiated (washed), but not chemically processed beyond those physical methods. This falls under Chapter 25. 2. Processed Fertilizers/Chemicals: If the ore has been chemically treated to extract phosphoric acid or converted into fertilizers (e.g., triple superphosphate), it falls under Chapter 31.
⚠️ Critical Distinction:
- If the material is natural rock (even with Al/Ca impurities) → Chapter 25 (Mineral Products).
- If the material is chemically processed fertilizer → Chapter 31 (Fertilizers).
- Most "ore" imports fall under Chapter 25.25.
📦 Part 2: HS Code Classification Details (2026 Latest Tariff Reference)
| HS Code | Product Description | Application Scenario | Chemical Processing Status |
|---|---|---|---|
2510.10.00.00 |
Phosphate rock dust (ground phosphate rock) | Raw mined phosphate, finely ground for transport or further processing. | ❌ No chemical treatment beyond grinding. |
2510.20.00.00 |
Phosphate rocks and phosphatic earth, whether or not crushed | Most common code for raw phosphate ore. Includes rocks with impurities like Aluminum, Calcium, Iron, etc. | ❌ Natural state, possibly washed/beneficiated. |
2835.25.00.00 |
Calcium phosphates (including natural apatite not further processed than ground) | If the product is specifically identified as "calcium phosphate" and meets purity standards for chemical use. | ⚠️ Borderline: Often confused with 2510. Check if "chemical grade" vs "mineral grade". |
3103.10.00.00 |
Superphosphates (natural phosphate treated to make fertilizers) | Fertilizer grade, chemically processed. | ✅ Chemically processed. |
🔍 Key Reminder for "Aluminum Calcium Phosphate":
- If the import is raw ore containing aluminum and calcium as impurities/minerals, it must be classified under2510.20.00.00(Phosphate rocks and phosphatic earth).
- Do not use2835(Chemicals) unless it is a purified chemical product, not an ore.
- Aluminum content does not change the classification to Chapter 28 or 38 unless it is a refined aluminum salt.
💰 Part 3: 2026 Latest Tariff Rate Details (Including Additional Taxes & Policy Surcharges)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: From November 10, 2025 (including subsequent imports)
🎯 1. 2510.20.00.00 —— Phosphate Rocks and Phosphatic Earth (Raw Ore)
| Item | Content |
|---|---|
| Base Rate | 0% (ad valorem) for most countries, but China-specific rules apply. |
| USITC Additional Duty | +25% (Under USITC Footnote 80 to Subchapter III of Chapter 99, 301 Tariffs) |
| IEEPA Additional Duty | +10% (For China/HK products under IEEPA, effective Nov 10, 2025) |
| Total Tariff Rate | 35% |
| Tax Calculation | CIF Value × 35% |

📌 Note:
- Dust is just a physical form of the rock. The tariff rate is identical to raw rocks.
- Air pollution concerns may require additional environmental declarations, but the tariff structure remains the same.
🛠️ Part 4: Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
✅ 1. Preparation Checklist (All Documents Required)
| Document | Must Provide | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must detail P2O5 content, CaO, Al2O3, and Moisture levels. |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Required for mineral dusts/rocks. |
| ✅ Certificate of Origin (CO) | ✔️ | Must clearly state Country of Origin: China. |
| ✅ Commercial Invoice | ✔️ | Must describe as "Phosphate Rock" or "Phosphatic Earth", not "Chemical" or "Fertilizer" unless processed. |
| ✅ Packing List | ✔️ | Net/Gross weight must match declaration. |
| ✅ Import License (if applicable) | ✔️ | Some states may require mineral import licenses; check local regulations. |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 "Raw Rock = 2510, Chem = 2835/3103. Don't Mix Up!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Raw phosphate rock with Al/Ca impurities | 2510.20.00.00 |
Misclassify as 2835 (Chemical) → Inspection delay + penalty. |
| Phosphate rock used for fertilizer production | Still 2510.20.00.00 |
Call it "Fertilizer" → Incorrect HS, 35% vs potential 0% for processed (but ore is ore). |
| Phosphate rock from non-China origin | 2510.20.00.00 |
Claim China origin → Fraud + heavy penalties. |
| Phosphate rock dust | 2510.10.00.00 |
Declare as "Soil" or "Sand" → Seizure. |
✅ 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| High Aluminum Content | If Al2O3 > 5%, emphasize it's Phosphate Rock, not Alumina ore. Misclassification as Aluminum ore (2620) leads to wrong tariff and environmental checks. |
| Phosphate Rock for Steel Industry | Some phosphate rock is used as a flux in steelmaking. Still declare as 2510.20.00.00. Do not declare as "Steel Flux" (Chapter 71 or 26). |
| Beneficiated Ore | If washed or dried, it's still 2510.20.00.00 as long as no chemical processing. Provide processing certificate if questioned. |
| Containerized vs Bulk | Bulk shipments require more detailed weight declarations. Containerized may require more photos. |
🌍 Part 5: Global Major Market Clearance Comparison (2026 Latest)

5-7.5% | BIS certification may be required. | Significant phosphate importer. |
| 🇧🇷 Brazil | 2510.20.00.00 |
0-2% | ANVISA approval for dust. | Major fertilizer producer. |
📌 Conclusion:
- USA is the most costly market for Chinese phosphate rock due to 35% cumulative tariffs.
- China, EU, and India have low or zero tariffs, making them more attractive for exports if origin can be diversified (e.g., Morocco, Jordan, but here we assume China origin).
📌 Part 6: Common Mistakes & Pitfall Guide (Lessons from Experience)
❌ Mistake 1: Declaring raw phosphate rock as "Calcium Phosphate" (2835.25) to avoid 35% tariff.
👉 Consequence: Customs inspection will reveal natural mineral structure, not chemical purity. Heavy fines + back taxes + potential fraud charges.
❌ Mistake 2: Ignoring Aluminum content and declaring as "Aluminum Ore" (2620).
👉 Consequence: Wrong HS code, incorrect tariff application, and potential environmental violations due to incorrect mineral classification.
❌ Mistake 3: Not disclosing "Phosphate" in the description.
👉 Consequence: Customs may classify as "Other Minerals" (2599) or "Industrial Waste", leading to delayed clearance and storage fees.
✅ Correct Practice:
"Phosphate Rock, Raw, Origin China, P2O5 XX%, CaO XX%, Al2O3 XX%, HS Code 2510.20.00.00"
🎯 Part 7: Conclusion: Precise Classification Saves Money!
🎯 Remember the Mnemonic:
🔹 "Raw Rock = 2510, Dust = 2510.10. China Origin = 35% Total!"
🔹 "Don't Call It Chemical, It's Mineral! Don't Hide the P2O5, It's Critical!"
📌 Pro Tip:
If your phosphate rock is beneficiated (washed) to reduce impurities, ensure the certificate reflects physical processing only. If it is chemically processed (e.g., phosphoric acid extraction), it leaves the "ore" category entirely.
For USA imports, consider pre-clearance consultation due to the high tariff and strict scrutiny on Chinese mineral imports.

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
