AI Analysis
š¾ Triple Superphosphate (TSP) ā The High-Purity Phosphorus Powerhouse
š HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Export Strategy š I. Product Definition & Classification: What is "Triple Superphosphate"?
Triple Superphosphate (TSP) is a concentrated water-soluble phosphate fertilizer. Unlike ordinary superphosphate, it is produced by treating phosphate rock with phosphoric acid rather than sulfuric acid. This process yields a product with a significantly higher concentration of diphosphorus pentoxide (PāOā ).
In international trade, TSP is strictly categorized under Mineral or Chemical Fertilizers, Phosphatic. It is distinct from mixed fertilizers (N-P-K) and simple calcium phosphates due to its manufacturing process and specific PāOā content.
ā ļø Key Distinction Point: - Ordinary Superphosphate: Contains ~20% PāOā , made with sulfuric acid, includes gypsum byproduct. - Triple Superphosphate (TSP): Contains ā„46-52% PāOā , made with phosphoric acid, no gypsum, higher purity. - Other Calcium Phosphates (e.g., Tricalcium Phosphate): Chemical salts, not necessarily processed fertilizers; fall under Chapter 28.
š¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, TSP is primarily classified under Chapter 31 (Fertilizers), specifically within the subheading for Superphosphates.
| HS Code | Product Description | Applicable Scenario | PāOā Content / Key Characteristic |
|---|---|---|---|
3103.11.00.00 |
Superphosphates: Containing by weight 35 percent or more of diphosphorous pentaoxide (PāOā ) | Triple Superphosphate (TSP), High-concentration superphosphate | ā Yes (Typically >46% PāOā ) |
3103.19.00.00 |
Superphosphates: Other | Ordinary superphosphate, low-grade superphosphate | ā No (Typically <35% PāOā ) |
2835.26.00.00 |
Other phosphates of calcium | Pure chemical calcium phosphates (not processed as fertilizer) | ā No (Not a fertilizer grade) |
2835.29.51.00 |
Other phosphates (General) | Miscellaneous phosphate chemicals | ā No |
3105.51.00.00 |
Fertilizers containing nitrates and phosphates | Mixed N-P fertilizers | ā No (TSP is single-element P) |
3105.59.00.00 |
Other mineral fertilizers with N & P | Mixed N-P fertilizers | ā No (TSP is single-element P) |
š Critical Reminder: - TSP is almost exclusively classified under
3103.11.00.00because its PāOā content invariably exceeds 35%. - Do NOT misclassify TSP as "Other phosphates of calcium" (2835.26.00.00) unless it is a pure chemical intermediate, not a commercial fertilizer. - Do NOT classify TSP under3105series; that chapter is for Mixed fertilizers (containing N and P). TSP is a Phosphatic fertilizer only.
š° III. 2026 Latest Tariff Rate Details (Including Additional Taxes & Policies)
ā Applicable Country: United States (US)
ā Origin: China (CN)
ā Effective Date: Ongoing (Section 301 & IEEPA tariffs apply)

š Explanation: - The base rate for superphosphates is 0%. - However, under Section 301 of the Trade Act of 1974, products of Chinese origin in this category are subject to an additional 25% tariff. - Total Liability: 25% of the CIF value. - Note: There are no IEEPA 10% additional taxes listed for this specific HS code in the provided data, unlike some electronics or panels. The burden is solely the 25% Section 301 tariff.
šÆ 2. Why NOT 3103.19.00.00 (Other Superphosphates)?
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% |
| Additional Tariff | +25.0% |
| Total Rate | 25.0% |
| Note | Even if misclassified as "Other," the rate remains 25%. However, customs will penalize for incorrect classification if the PāOā content clearly exceeds 35%. |
ā ļø Risk: Misclassifying TSP (
3103.11) as "Other Superphosphate" (3103.19) may trigger audits. If your lab report shows >35% PāOā , you must use3103.11.00.00.
š ļø IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
ā 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Purpose |
|---|---|---|
| Certificate of Analysis (COA) | āļø Yes | Must explicitly state % PāOā
. If >35%, it forces 3103.11.00.00. |
| Fertilizer Label | āļø Yes | Must show N-P-K ratio (e.g., 0-46-0), usage instructions, and manufacturer info. |
| Safety Data Sheet (SDS) | āļø Yes | Required for hazardous material screening (even if non-hazardous, it proves chemical stability). |
| Bill of Lading (B/L) | āļø Yes | Must match commercial invoice exactly. |
| Commercial Invoice | āļø Yes | Clearly state "Triple Superphosphate" or "TSP," not generic "Fertilizer." |
| Packaging List | āļø Yes | Detail bag weight, net/gross weight, and pallet configuration. |
ā 2. Declaration Strategy (Key Mantra)
š„ "Label Matches COA, PāOā Defines the Code, TSP is 3103.11!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Standard TSP (0-46-0) | 3103.11.00.00 with description "Triple Superphosphate, 0-46-0" |
Generic "Phosphate Fertilizer" ā Audits & Delays |
| TSP with Urea Coating | Still 3103.11.00.00 (if P content > N) |
Split declaration ā Penalty |
| Ordinary Superphosphate (0-20-0) | 3103.19.00.00 |
Using 3103.11 ā Over-declaration risk |
| Mixed N-P Fertilizer | 3105.xxxx |
Using 3103 ā Major Classification Error |
ā 3. Special Situations & Handling
| Situation | Handling Advice |
|---|---|
| High Moisture Content | Ensure drying specifications are met; excess moisture may lead to re-weighing or rejection. |
| Dust Control | TSP can be dusty. Ensure bags are sealed and palletized to avoid spillage during transit. |
| Corrosive Packaging | Use high-quality PE-lined bags. Phosphoric acid residues can corrode metal pallets or container walls. |
| Lab Testing Discrepancy | If CBP tests your shipment and finds PāOā
>35%, but you declared 3103.19, expect Back Duties + Interest. |
š V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Remarks |
|---|---|---|---|---|

š Conclusion: - USA imposes a 25% tariff on TSP from China. - Classification is strict: Must prove PāOā >35% for
3103.11.00.00. - Lab Reports are King: Your Certificate of Analysis is the most important document for clearance.
š VI. Common Errors & Pitfalls (Blood & Tears Lessons)
ā Error 1: Declaring TSP as "Other Calcium Phosphates" (2835.26.00.00)
š Consequence: Even if base rate is 0%, misclassification leads to civil penalties for fraud or negligence. TSP is a fertilizer, not a pure chemical.
ā Error 2: Ignoring PāOā
Content
š Consequence: If PāOā
is 46% but declared as "Other Superphosphate" (3103.19), customs will demand a new lab test at your expense and reclassify, causing port delays.
ā Error 3: Mixing TSP with Urea in Declaration
š Consequence: If the shipment is a physical mixture, it may fall under 3105. If it's separate bags, declare separately. Mixed declarations are red flags.
ā Correct Practice:
"Triple Superphosphate, Fertilizer Grade, 0-46-0, PāOā 46% min, in 50kg PE-lined bags, Model TSP-50, Certificate of Analysis Attached."
šÆ VII. Conclusion: Precision in Phosphates Saves Money!
šÆ Remember the Mantra:
š¹ "TSP is Super, PāOā is Key, >35% is Code 11, 25% is Fee!" š¹ "Lab Report First, Description Second, Classification Last!"
š Pro Tip: If your TSP is destined for the US market, factor the 25% additional tariff into your pricing strategy. Consider duty drawback programs if re-exporting, or explore FTZ (Foreign Trade Zone) storage to defer duty payment.

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