❄️ Bromofluorocarbon Refrigerant Analysis Standard
🌐 HS Code Reference & Customs Clearance Guide | 2026 Harmonized System Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What are Bromofluorocarbons?
Bromofluorocarbons (BFCs) are a class of halocarbon compounds containing bromine, fluorine, carbon, and sometimes chlorine or hydrogen. In the context of international trade and refrigeration, they are historically significant as Halons (specifically Halon-1301, Halon-1211, etc.), which are potent fire suppressants, or as specific refrigerant intermediates or blended refrigerants in specialized industrial applications.
However, it is critical to note that most bromofluorocarbons used in fire suppression are strictly regulated or banned under the Montreal Protocol due to their high Ozone Depletion Potential (ODP). As "refrigerants," they are rarely used in modern consumer systems but may appear in specialized industrial processes, laboratory standards, or legacy systems.
⚠️ Key Distinction:
- If the product is primarily a fire extinguishing agent (Halon), it is generally classified under Chapters 38 or 36 (Chemical Preparations/Explosives), but often requires special permits.
- If it is a pure chemical substance used as a refrigerant or intermediate, it falls under Chapter 29 (Organic Chemicals).
- If it is a preparation/mixture (e.g., a blend of refrigerants), it typically falls under Chapter 38.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Reference)

Other halogenated derivatives of acyclic hydrocarbons | Pure Bromofluorocarbons (e.g., Bromotrifluoromethane) | ✅ Yes (Bromo-Fluoro) |
2903.49.90.00 |
Other halogenated derivatives of acyclic hydrocarbons, n.e.s. | Specific BFCs not listed elsewhere in 2903.49 | ✅ Yes |
3824.99.92.00 |
Prepared binders for foundry mold/core; chemical products n.e.s. | Refrigerant blends, mixtures, or stabilized forms | ✅ Yes (if mixture) |
3824.99.94.00 |
Other chemical products and preparations n.e.s. | Industrial refrigerant preparations, analysis standards | ✅ Yes |
3822.00.00.00 |
Diagnostic or laboratory reagents on a backing | Analysis Standard (if sold as a certified reference material) | ✅ Yes (if CRMs) |
2803.00.00.00 |
Carbon (Soot, etc.) | Not applicable | ❌ No |
🔍 Critical Note:
- Pure Bromofluorocarbons (single chemical entity) are typically classified under Heading 2903 (Halogenated Hydrocarbons).
- Refrigerant Blends (mixtures of multiple gases) are classified under Heading 3824 (Preparations of chemical products).
- Analysis Standards (Certified Reference Materials) are classified under Heading 3822 if sold for diagnostic/laboratory use.
- Environmental Compliance: Imports of substances regulated under the Montreal Protocol (like most Halons) require Prior Informed Consent (PIC) documentation and are often prohibited unless for essential uses with exemptions.

🛠️ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
✅ 1. Required Documentation Checklist (Non-negotiable)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ MSDS (SDS) | ✔️ | Safety Data Sheet detailing chemical composition, hazards, and handling. |
| ✅ Chemical Identity | ✔️ | Exact IUPAC name, CAS number, and purity % for each component. |
| ✅ Environmental Permit | ✔️ | Critical: Proof of compliance with Montreal Protocol (if Halon/BFC). |
| ✅ Certificate of Analysis | ✔️ | For "Analysis Standard," provide certified purity and traceability. |
| ✅ Commercial Invoice | ✔️ | Must specify "Refrigerant," "Chemical Intermediate," or "Lab Reagent" accurately. |
| ✅ Packing List | ✔️ | Details of quantity, weight, and packaging type. |
| ✅ EPA/DOE Exemption | ✔️ | If applicable, document any essential-use exemption for ODS substances. |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Pure is 29, Mixture is 38, Standard is 3822, Enviro Permits are a MUST!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Pure Bromofluorocarbon | 2903.49.00.00 with CAS # |
Generic "Chemical" |
| Refrigerant Blend | 3824.99.94.00 with % Composition |
"Refrigerant Gas" only |
| Lab Analysis Standard | 3822.00.00.00 with "Certified Reference Material" |
"Chemical Standard" |
| Halon Fire Extinguisher | Prohibited/Restricted unless exempt | Declare as "Safety Equipment" |
✅ 3. Special Circumstances
| Situation | Handling Advice |
|---|---|
| Ozone-Depleting Substances (ODS) | Most Bromofluorocarbons are ODS. Import requires EPA Section 618 Permit. Without it, shipment will be seized. |
| Analysis Standards | Ensure the product is marketed as a lab reagent, not an industrial refrigerant, to justify 3822 classification. |
| Small Quantities | Even small quantities require proper documentation. De Minimis (Section 321) does NOT apply to chemicals under Section 301. |
| Transshipment | Do not route through countries with weak environmental enforcement; traceability audits are common. |
🌍 V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 US | 2903.49.00.00 or 3824.99.94.00 |
35-40.7% | EPA Permit + TSCA | Strict ODS control |
| 🇨🇳 China | 2903.49.00.00 |
5-10% | None | No Section 301 surtax |
| 🇪🇺 EU | 2903.49.00 or 3824.99 |
0-6.5% | REACH Registration | F-Gas Regulation applies |
| 🇬🇧 UK | 2903.49.00 |
0-6.5% | UK REACH | Post-Brexit rules apply |
| 🇯🇵 Japan | 2903.49.00 |
0-6% | Chemical Subst Control Law | Strict import monitoring |
📌 Conclusion:
- US and EU have the strictest environmental controls on Bromofluorocarbons.
- Tariffs in the US are high (35-40%), making it expensive.
- China has lower tariffs but may restrict exports of regulated chemicals.
- Always verify ODS status before shipping.
📌 VI. Common Mistakes & Pitfalls (Blood & Tears)
❌ Mistake 1: Declaring as "General Chemical" without CAS Number
👉 Consequence: Customs detention, seizure, and fines.
❌ Mistake 2: Ignoring Montreal Protocol Compliance
👉 Consequence: Illegal import. Shipment destroyed or returned at importer's expense.
❌ Mistake 3: Misclassifying Mixture as Pure Chemical
👉 Consequence: Incorrect tariff (e.g., 5.7% vs 5.3%), leading to underpayment and penalties.
❌ Mistake 4: Using "Refrigerant" for Lab Standards
👉 Consequence: Customs may classify as industrial chemical, triggering higher tariffs and environmental permits.
✅ Correct Approach:
"Bromotrifluoromethane, 99.9% Purity, CAS# 75-63-8, Certified Reference Material, EPA Permit #XXXXX"
🎯 VII. Conclusion: Professional Declaration, Time & Cost Saving!
🎯 Remember the Mnemonic:
🔹 "Pure is 29, Mixture is 38, Standard is 3822, Enviro Permits are a MUST!"
🔹 "ODS is a Red Line, No Permit, No Entry!"
📌 Pro Tip:
If your product is not an ODS (e.g., HFCs or HFOs instead of BFCs), the classification and tariff may differ significantly. Verify the chemical composition with a certified lab before shipping.
📣 Immediate Action:
📞 Contact a licensed customs broker + Provide SDS + Apply for EPA Permit (if applicable)
🚀 Ensure your Bromofluorocarbon shipment clears customs smoothly and legally.
✨ Professional Clearance Starts with Accurate Classification!
💼 Every dollar of tariff cost is worth calculating precisely!

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
