🧪 Diagnostic Kits & Laboratory Reagents: Carbon Tetrachloride Containing Products
🌐 HS Code Reference & Customs Clearance Guide | 2026最新税则全解析 | Professional Clearance Strategy
📌 1. Product Definition & Classification: What Are These Products?
These products fall under Chapter 38 of the Harmonized System (HS), specifically covering "Prepared Diagnostic or Laboratory Reagents" and "Certified Reference Materials."
The key distinction for classification is whether the reagents are on a backing (e.g., test strips, slide mounts) or prepared in bottles/vials, and whether they contain specific hazardous solvents like Carbon Tetrachloride or Methyl Chloroform.
⚠️ Critical Classification Point:
- Products containing Carbon Tetrachloride or Methyl Chloroform are strictly regulated due to environmental and safety concerns.
- They are excluded from Heading 3006 (Medical/Scientific preparations) and classified under Heading 3822.
- Specific HS codes depend on whether the product is a diagnostic reagent on a backing or other prepared reagents.
📦 2. HS Code Classification Details (2026 Authoritative Reference)
| HS Code | Product Description | Applicable Scenario | Contains Carbon Tetrachloride? |
|---|---|---|---|
3822.19.00.10 |
Diagnostic or laboratory reagents on a backing; Other containing antigens or antisera; Containing methyl chloroform or carbon tetrachloride | Test strips, slide-based diagnostics with specific antigens/antisera | ✅ Yes |
3822.19.00.40 |
Diagnostic or laboratory reagents on a backing; Other; Containing methyl chloroform or carbon tetrachloride | Other prepared reagents on backing not covered above, containing the specified solvents | ✅ Yes |
🔍 Key Clarification:
- Both codes apply to reagents on a backing (e.g., dipsticks, test kits mounted on cards).
- The presence of Carbon Tetrachloride (CCl₄) or Methyl Chloroform (1,1,1-trichloroethane) triggers this specific subheading.
- These chemicals are ozone-depleting or hazardous, hence the specific tracking.

🛠️ 4. Customs Clearance Practical Advice (Actionable Guide)
✅ 1. Required Documentation Checklist
| Document | Required? | Notes |
|---|---|---|
| Product Specification Sheet | ✔️ | Must explicitly state composition, including % of Carbon Tetrachloride |
| Safety Data Sheet (SDS) | ✔️ | Critical: Must confirm hazardous nature and handling instructions |
| Commercial Invoice | ✔️ | Clearly describe as "Diagnostic Reagents on Backing" |
| Certificate of Origin | ✔️ | To prove origin (China) |
| Import License/Permit | ✔️ | May require EPA or FDA approval due to CCl₄ content |
| Packing List | ✔️ | Detail packaging to show it's not a bulk chemical shipment |
✅ 2. Clearance Tips (Key Phrases)
🔥 “Declare as Reagent, Not Solvent! Highlight ‘On Backing’!”
| Scenario | Correct Declaration | Incorrect Declaration |
|---|---|---|
| Test strip with CCl₄ | 3822.19.00.10 or .40 |
Misclassified as 2903.42 (Carbon Tetrachloride) → High duty + EPA issues |
| Liquid reagent in bottle | Not covered by these HS codes | Must use other 3822 subheadings (e.g., 3822.00) |
| Bulk chemical solvent | Different HS Code | Do not use 3822 for bulk solvents |
⚠️ Critical Warning:
- Carbon Tetrachloride is a controlled substance under international environmental agreements (Montreal Protocol).
- Ensure EPA compliance and proper labeling.
- Misclassification as bulk solvent can lead to seizure or heavy fines.
✅ 3. Special Considerations
| Situation | Recommendation |
|---|---|
| FDA Regulated Products | If intended for medical diagnosis, ensure FDA registration |
| Hazardous Material Transport | Must comply with DOT/IATA dangerous goods regulations |
| Mixed Shipments | Keep diagnostic kits separate from bulk chemicals to avoid misclassification |
🌍 5. Global Customs Comparison (2026)
| Country/Region | Recommended HS Code | Tariff | Key Requirement | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3822.19.00.10/.40 |
0% | FDA/EPA Compliance | Zero tariff, but strict environmental controls |
| 🇪🇺 EU | 3822.00 |
Varies | REACH Registration | CCl₄ heavily restricted; may require ban exemption |
| 🇨🇳 China | 3822.00 |
0% | Import License | Domestic use may be restricted |
| 🇯🇵 Japan | 3822.00 |
0%~5% | Fire Services Act | CCl₄ phased out in many applications |
📌 Conclusion:
- USA offers 0% tariff, but environmental compliance is paramount.
- EU and Japan may ban or restrict CCl₄ entirely due to ozone depletion.
- Always verify destination country regulations before shipping.
📌 6. Common Mistakes & Pitfalls
❌ Mistake 1: Declaring as "Carbon Tetrachloride Chemical"
👉 Result: Classified under 2903.42, subject to EPA restrictions, potential duty >5% + penalties.
❌ Mistake 2: Omitting "On Backing" in Description
👉 Result: Customs may suspect bulk liquid, leading to delays for hazardous material inspection.
❌ Mistake 3: Ignoring SDS Requirements
👉 Result: Carrier rejection or customs hold due to missing hazardous material documentation.
✅ Correct Approach:
"Diagnostic Test Strip Containing Carbon Tetrachloride, On Backing, For Laboratory Use, SDS Attached, FDA Registered"
🎯 7. Conclusion: Precision in Classification, Efficiency in Clearance
🎯 Remember:
🔹 "Reagent on Backing + CCl₄ = 3822.19.00"
🔹 "Zero Tariff, But High Compliance"
🔹 "SDS is Your Best Friend"
📌 Pro Tip:
- If your product is liquid-based (not on backing), it may fall under 3822.00.00 or other subheadings.
- Always consult EPA guidelines for Carbon Tetrachloride usage and import.
- Consider alternative solvents if CCl₄ poses regulatory hurdles in destination countries.
📣 Immediate Action:
📞 Engage a licensed customs broker with chemical/diagnostic expertise.
📄 Prepare SDS and FDA documentation in advance.
🚀 Ensure compliance with environmental laws to avoid shipment rejection.
✨ Professional clearance starts with accurate classification!
💼 Zero tariff is great, but zero risk is better!

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
