π§ͺ Calcium Phosphate (Calcium Phosphates)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Compliance Strategy
π I. Product Definition & Classification: What Exactly is "Calcium Phosphate"?
Calcium phosphate refers to a family of minerals and chemical compounds containing calcium ions and orthophosphate ions. In international trade, these materials are not treated as a single entity but are split based on their purity and end-use:
- Industrial/Chemical Grade (High Purity): Used in pharmaceuticals, food additives, or high-tech ceramics. These fall under Chapter 28 (Inorganic Chemicals).
- Agricultural/Fertilizer Grade (Lower Purity): Used as soil amendments or livestock feed supplements. These fall under Chapter 31 (Fertilizers).
β οΈ Key Distinction Point:
- If the product is a pure chemical compound (e.g., monocalcium phosphate, tricalcium phosphate) used for industrial, food, or pharma purposes β Classified under 2809.20.00.
- If the product is a mixture or natural mineral primarily used as a fertilizer (containing phosphorus as a key nutrient) β Classified under 3105.40.00.
π¦ II. HS Code Classification Details (2026 Latest Authorized Reference)
Based on the provided data, the following HS Codes are applicable for Calcium Phosphate imports.
| HS Code | Product Description | Summary Reason | Applicability |
|---|---|---|---|
2809.20.00.20 |
Phosphoric Acid Derivatives (Industrial Grade) | Material Match: Pure chemical compounds of phosphoric acid derivatives. | β Chemical/Industrial |
2809.20.00.30 |
Phosphoric Acid Derivatives (Core Material Consistent) | Core Material Consistent: High-purity calcium phosphate compounds structurally aligned with phosphoric acid salts. | β Chemical/Industrial |
3105.40.00.50 |
Phosphorus-Containing Fertilizer Raw Materials | Material Match: Calcium phosphate used as a raw material or active ingredient in fertilizers. | β Agricultural/Fertilizer |
π Critical Reminder:
- Purity is King: If the Calcium Phosphate is >99% pure and intended for non-agricultural use, it must go to Chapter 28 (2809.20.00).
- Fertilizer Exception: If it is a bulk mineral powder or mixture intended for soil enhancement, it falls under Chapter 31 (3105.40.00).
- Misclassification Risk: Declaring high-purity pharma-grade calcium phosphate as fertilizer (3105) may lead to penalties for tax evasion; declaring low-purity fertilizer as chemical (2809) may trigger unnecessary purity tests.

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
