🔥 Alcohol-Based Flame Retardant Mixture (Liquid Formulation)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
📌 I. Product Definition & Classification: What Exactly Is It?
An Alcohol-Based Flame Retardant Mixture is a liquid chemical formulation where the solvent is primarily alcohol (ethanol, methanol, isopropanol, etc.), and the active ingredient consists of flame retardant chemicals (such as ammonium polyphosphate, halogenated compounds, or phosphates).
In international trade, this product is generally classified under Chapter 38 (Miscellaneous Chemical Products) or Chapter 29 (Organic Chemicals) depending on the specific chemical composition and concentration. However, for most commercial "mixtures" used for surface treatment or fireproofing, HS Code 3824 is the most common and safest classification.
⚠️ Key Distinction:
- If it is a pure chemical substance (single compound) → Check Chapter 29.
- If it is a mixture (chemicals dissolved in alcohol solvent) → Check HS 3824 (Prepared binders, prepared fire retardants, etc.).
- Alcohol Content Impact: If alcohol content is very high, it might be classified under HS 2207 (Undenatured Ethyl Alcohol) or HS 2208 (Spirits), but the presence of flame retardant additives usually pushes it to 3824.90 to ensure safety regulations are met.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Solvent Type | Active Ingredient |
|---|---|---|---|---|
3824.90.91.00 |
Other prepared binders for foundry molds; Other prepared chemicals (Including fire retardants) | General purpose liquid fire retardant sprays, coatings | Alcohol/Water Mix | Phosphates, Ammonium Salts, Halogenated compounds |
3824.90.96.00 |
Other prepared chemicals | Specialized industrial fire retardants not specified elsewhere | Any Organic Solvent | Custom Formulations |
2207.10.00.00 |
Undenatured Ethyl Alcohol (Alcohol) | ONLY IF it contains NO flame retardant additives (Pure solvent) | Pure Ethanol | None |
2207.20.00.00 |
Ethyl Alcohol and Other Spirits, Denatured | Denatured alcohol without significant chemical additives | Denatured Ethanol | Minimal/None |
2903.xx.xx |
Halogenated Organic Compounds | Pure halogenated flame retardant substances (e.g., Tris(1-chloro-2-propyl) phosphate) | Pure Chemical | Specific Halogen Compound |
🔍 Critical Reminder:
- Do NOT classify as2207(Alcohol) if it contains flame retardant chemicals. Customs will reclassify it to 3824 and may impose penalties for misdeclaration.
- HS 3824 is the "catch-all" for prepared mixtures. It is the most accurate for "Alcohol-Based Flame Retardant Mixtures."
- If the product is a powder, it would fall under 3824.60. Since yours is liquid/alcohol-based, stick to 3824.90.

🔥 "Disclose Chemicals, Label Hazards, SDS is King, Alcohol is Flammable!"
| Situation | Correct Declaration Method | Wrong Practice |
|---|---|---|
| Liquid with High Alcohol | Declare as 3824.90 + Class 3 Flammable Liquid |
Declare as non-hazardous → Seizure & Fines |
| Pure Flame Retardant | Check Chapter 29 if no solvent | Use 3824 for pure chemicals → Misclassification |
| Mixed with Water | If alcohol <24%, may be non-flammable | Assume all alcohol-based = flammable → Over-packaging |
| OEM Brand | Provide client order + formula agreement | Omit ingredient details → Customs Hold |
✅ 3. Special Handling Cases
| Situation | Handling Advice |
|---|---|
| Flash Point < 60°C | Must be declared as Class 3 Flammable Liquid. Requires UN packaging and proper hazard labels. |
| Flash Point > 60°C | May be considered non-flammable for transport, but still subject to chemical import regulations. |
| Halogenated Flame Retardants | Check for POPs (Persistent Organic Pollutants) restrictions. Some halogenated compounds are banned or restricted. |
| Phosphorus-Based Retardants | Generally safer, but still subject to SDS review. |
| Small Samples (< $800) | NOT eligible for de minimis due to chemical nature. Must be formally entered. |

📌 VI. Common Mistakes & Pitfall Avoidance (Blood Lessons)
❌ Mistake 1: Declaring as "Alcohol" (HS 2207) to avoid chemical regulations
👉 Consequence: Customs will reclassify to 3824, impose penalties, and seize goods if not properly declared.
❌ Mistake 2: Ignoring the Flash Point in SDS
👉 Consequence: If flash point < 60°C, it is Class 3 Flammable Liquid. Failure to label properly leads to transport rejection or fines.
❌ Mistake 3: Omitting CAS Numbers for flame retardants
👉 Consequence: Customs cannot verify the product, leading to delays and additional testing fees.
❌ Mistake 4: Assuming small quantities are exempt from de minimis
👉 Consequence: Chemicals are never de minimis eligible in the US. Attempting this leads to entry rejection.
✅ Correct Practice:
"Alcohol-Based Flame Retardant Mixture, Liquid, Flash Point XX°C, Contains [Chemical Name] CAS# XXXXX, UN 1170 (if flammable), For Industrial Use Only, Not for Human Consumption."
🎯 VII. Conclusion: Professional Declaration, Safe Passage, Cost Efficiency!
🎯 Remember the Mantra:
🔹 "Chemicals First, Alcohol Second, SDS is Law, Flammability is Key!"
🔹 "HS 3824 for Mixtures, HS 29 for Pure, Never Mix Up, or Lose Your Cup!"
📌 Pro Tip:
If your flame retardant contains halogenated compounds, check EPA and REACH restrictions. Some are banned or require special permits.
Consider applying for a Binding Ruling from Customs to confirm the exact HS code and tariff rate before shipping.

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
