🧪 Calcium Phosphate (Calcium Phosphates)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Compliance Strategy
📌 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).
⚠️ Key Distinction Point:
- If the product is a pure chemical compound (e.g., monocalcium phosphate, tricalcium phosphate) used for industrial, food, or pharma purposes → 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) → Classified under 3105.40.00.
📦 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. | ✅ 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. | ✅ 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. | ✅ Agricultural/Fertilizer |
🔍 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.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
