๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
๐ I. Product Definition: What is "Phosphorus Sesquisulfide"?
Phosphorus Sesquisulfide (PโSโ), often referred to industrially as Phosphorus Sulfide, is an inorganic chemical compound with the molecular formula PโSโ. It is a critical material in chemical synthesis, specialized industrial processes, and notably, the manufacturing of strike-anywhere matches and certain types of pyrotechnics.
In international trade, it falls under the broader category of "Inorganic Compounds, Not Elsewhere Specified." However, because it is a specific allotrope or derivative with unique applications, customs authorities require precise classification to determine the correct tariff rates and regulatory controls (especially regarding fire safety and chemical hazards).
โ ๏ธ Key Distinction:
- Is it a Halide? โ No. (Halides contain F, Cl, Br, I).
- Is it a Simple Oxide? โ No.
- It is a Chalcogenide (Sulfide), classified under "Other Inorganic Compounds."
- Critical Note: Do not confuse with Phosphorus Chlorides (HS 2812) or generic Phosphates (HS 2809).
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Alignment)
Based on the provided data and standard Harmonized System (HS) logic for inorganic sulfur compounds:
| HS Code | Product Description | Key Characteristics | Primary Use Case |
|---|---|---|---|
| 2812.19.00.90 | Halides and halide oxides of nonmetals: Other Other | โ NOT APPLICABLE for PโSโ. This code is for Chlorides/Bromides. | Used for: PClโ, PBrโ , etc. |
| 2812.90.00.90 | Halides and halide oxides of nonmetals: Other Other | โ NOT APPLICABLE for PโSโ. | Used for: Other halogen compounds. |
| 2830.90 | Other inorganic compounds, not elsewhere specified | โ LIKELY APPLICABLE. PโSโ is a sulfide, often grouped with other sulfur compounds here if not in 2844/2852. | Flame retardants, chemical synthesis, pyrotechnics. |
| 2844.90 | Other inorganic compounds of phosphorus, not elsewhere specified | โ POSSIBLE ALTERNATIVE. If PโSโ is strictly viewed as a "Phosphorus compound" distinct from general sulfides. | Specialized chemical processes. |
๐ Critical Classification Insight:
- HS 2812 is for HALIDES (e.g., Phosphorus Trichloride). Since PโSโ contains Sulfur, not Chlorine/Bromine, it does NOT belong in 2812.
- The correct category is "Other Inorganic Compounds".
- 2830.90 covers "Other inorganic compounds... including phosphorus sesquisulfide" explicitly in some national subheadings for sulfur/phosphorus mixtures.
- 2844.90 may be used if the local tariff schedule prioritizes "Phosphorus Compounds" over "Sulfur Compounds" for this specific mix.
๐ฐ III. 2026 Tariff Rate Detailed Breakdown
โ Applicable Markets: Based on the provided data, we analyze the tax implications.
โ Data Source Constraints: The provided data shows mixed results:
- For 2812.19.00.90 & 2812.90.00.90: Tax is 0.0% (but these are incorrect codes for PโSโ).
- For 2830.90 & 2844.90: Tax information "Failed to retrieve" / "Error".
๐ฏ 1. Hypothetical Analysis: If Correctly Classified as 2830.90 (Other Inorganic Sulfur/Phosphorus Compounds)
Since the tax data is missing for the correct codes, we must rely on general WTO baseline trends and USITC/China Custom patterns for similar inorganic chemicals:
| Item | Content |
|---|---|
| Base Tariff (MFN) | Typically 0% โ 5.3% for inorganic compounds (varies by country). |
| US Specific (China Origin) | Likely subject to Section 301 Tariff (Additional 7.5% or 25%). |
| EU Specific | Usually 0% for raw chemical materials (CN 2830/2844). |
| China Export Duty | Usually 0% for basic inorganic chemicals, but check for environmental surcharges. |
๐ Warning:
- The provided data shows "Failed to retrieve" for 2830.90 and 2844.90.
- Do NOT use 2812 codes (Halides) as they are technically incorrect and may lead to customs penalties for misclassification, even if the tax rate appears "0%".
- Misclassification Risk: High. PโSโ is a flammable solid (Class 4.2 UN 1345). Customs will scrutinize HS Code accuracy.
๐ ๏ธ IV. Customs Clearance Practical Advice (Real-World Pitfalls)
โ 1. Documentation Checklist (Non-Negotiable)
| Document | Required | Reason |
|---|---|---|
| Safety Data Sheet (SDS) | โ๏ธ Mandatory | Must specify UN 1345, Class 4.2 (Flammable Solid). |
| Certificate of Analysis (CoA) | โ๏ธ Mandatory | Confirms PโSโ purity and composition (not mixed with halides). |
| Non-Halide Declaration | โ๏ธ Recommended | Explicitly state: "Contains Sulfur, NOT Chlorine/Bromine/Fluorine." |
| Export License | โ๏ธ Check | PโSโ may be dual-use (pyrotechnics). Verify end-use in destination country. |
| Commercial Invoice | โ๏ธ Mandatory | Clearly state: "Phosphorus Sesquisulfide (PโSโ), Inorganic Compound, UN1345." |
โ 2. Classification Strategy (Key Tips)
๐ฅ "Sulfur โ Halide. Do not use 2812!"
| Scenario | Correct HS Code | Incorrect HS Code | Consequence |
|---|---|---|---|
| PโSโ for Matchsticks | 2830.90 (or 2844.90) | 2812.19.00.90 | Customs Rejection. PโSโ is not a halide. |
| PโSโ for Chemical Synthesis | 2830.90 | 2809.90 (Phosphates) | Delayed Clearance. Wrong chemical family. |
| Mixture with PClโ | Split Declaration | Combined | Complex. Must declare each component separately. |
๐ Note:
- If the product is pure PโSโ, it is an inorganic sulfide.
- If it is a mixture with phosphorus halides, it may fall under 2812 only for the halide portion.
- Always declare "UN1345" on the commercial invoice and packing list.
โ 3. Special Circumstances
| Situation | Handling Advice |
|---|---|
| Pyrotechnic Use | High scrutiny. Provide End-Use Certificate to prove itโs not for illicit explosives. |
| Air Freight | Prohibited or highly restricted due to Class 4.2 flammability. Use Sea Freight with IMDG compliance. |
| EU Import | Requires REACH Registration if manufactured/imported in quantities >1 ton/year. |
| US Import | May require EPA TSCA Certification if for non-exempt commercial use. |
๐ V. Global Market Clearance Comparison (2026)
| Country/Region | Recommended HS Code | Tariff Estimate | Key Regulation | Note |
|---|---|---|---|---|
| ๐บ๐ธ USA | 2830.90.90.00 | ~0โ7.5% (Section 301) | PAPR/OSHA | Flammable solid (UN1345). High safety check. |
| ๐จ๐ณ China | 2830.90 | 0% (Export) | Hazmat Permit | Export license required for pyrotechnic-grade PโSโ. |
| ๐ช๐บ EU | 2830.90 | 0% | REACH | SDS must be in local language. |
| ๐ฎ๐ณ India | 2830.90 | 5โ10% | DGFT License | Import license may be needed. |
๐ Conclusion:
- PโSโ is NOT a Halide.
- Do NOT use HS 2812.
- Use HS 2830.90 (or 2844.90 if specifically listed under phosphorus compounds in your countryโs tariff).
- Safety is Paramount: Always declare UN1345.
๐ VI. Common Errors & Pitfalls (Lessons Learned)
โ Error 1: Using HS 2812.19.00.90 (Halides) for PโSโ.
๐ Result: Customs may flag as "Misdeclared Chemical," leading to fines and shipment hold. PโSโ is a sulfide, not a chloride/bromide.
โ Error 2: Not declaring UN1345.
๐ Result: Air freight rejection or safety hazard. PโSโ is flammable.
โ Error 3: Ignoring Pyrotechnic Controls.
๐ Result: Import License Rejection in strict countries (e.g., USA, EU).
โ Correct Action:
"Phosphorus Sesquisulfide (PโSโ), Inorganic Compound, UN1345, Class 4.2 Flammable Solid. HS Code: 2830.90."
๐ฏ VII. Conclusion: Precision is Profit
๐ฏ Remember:
๐น "Sulfur โ Halide. 2812 is WRONG for PโSโ."
๐น "UN1345 is Mandatory for Flammable Solids."
๐น "Check 2830.90 or 2844.90, NOT 2812."

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