HS Code for Calcium Phosphates 2025 Guide
TL;DR: **HS codes for calcium phosphates fall under 2835.25 (dicalcium phosphate) and 2835.26 (other forms) in the 2025 HS codes guide.** Key 2025 updates include US HTS mandates, GCC 12-digit extensions, and EU refinements for tariff compliance—use tables and steps below for quick classification.
What Is the HS Code for Calcium Phosphates in 2025?
The HS code for calcium phosphates centers on Chapter 28, heading 2835 of the 2025 Harmonized System.** These 6-digit codes standardize global trade classification managed by the World Customs Organization (WCO).
- Universal 6-digit base for all countries
- Extended digits for national tariff schedules (e.g., 10-digit US HTS)
- Periodic updates; next major WCO revision in 2027
- Vital for calculating duties, trade statistics, and regulatory compliance
Calcium phosphates, used in fertilizers, animal feed, and pharmaceuticals, require precise HS code classification to avoid penalties.
Primary HS Codes for Calcium Phosphates: 2025 Breakdown
Key HS codes for calcium phosphates in 2025 are 2835.25 for dicalcium and 2835.26 for others.**
| HS Code | Description | Main Applications | 2025 Notes |
|---|
| 2835.25 | Calcium hydrogenorthophosphate (dicalcium phosphate) | Animal feed, fertilizers, food additives | High demand in agribusiness |
| 2835.26 | Other calcium phosphates (e.g., monocalcium, tricalcium) | Pharmaceuticals, ceramics, water treatment | Includes hydroxyapatite variants |
- Dicalcium phosphate: Optimal Ca:P ratio (1.29:1) for livestock nutrition
- Other forms: Vary by purity and processing for industrial uses
- Always verify with product SDS for exact subheading
