🏥 Medical Catgut Suture (Sterile, for Research)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 1. Product Definition & Classification: What Exactly is "Medical Catgut Suture"?
Medical catgut sutures are sterile surgical threads traditionally made from purified collagen derived from the submucosa of sheep or cattle intestines. In international trade, despite the name "catgut," modern surgical sutures are rarely made from cats. They are categorized under Chapter 30 (Pharmaceutical Products) due to their specific medical use and sterile nature.
For Research Purposes, the classification remains strict because these items are classified as "Pharmaceutical Goods Specified in Note 4 to Chapter 30." This chapter covers specific sterile surgical materials, including catgut, synthetic absorbable sutures, and tissue adhesives.
⚠️ Key Distinction for Research Use: - Even if intended for in vitro research or non-clinical trials, sterile surgical catgut is legally classified as a pharmaceutical good in many jurisdictions (including the US under HTSUS Chapter 30 notes). - It is not classified as a simple textile or laboratory consumable (Chapter 50/63 or 3822) because its primary identity is as a sterile surgical implant material. - Placebos/Clinical Trial Kits: If the suture is packaged with medicinal preparations as part of a blinded trial kit, it falls under a specific sub-category. If it is standalone sterile catgut, it falls under the general sterile surgical goods category.
📦 2. HS Code Classification Details (Based on Provided Data)
Based on the <DATA> provided, the relevant HS Codes for Sterile Surgical Catgut and related research packs are:
| HS Code | Product Description | Application Scope | Tax Rate (Total) |
|---|---|---|---|
| 3006.10.01.00 | Sterile surgical catgut, similar sterile suture materials (including sterile absorbable surgical or dental yarns) and sterile tissue adhesives for surgical wound closure; sterile laminaria and sterile laminaria tents; sterile absorbable surgical or dental hemostatics; sterile surgical or dental adhesion barriers, whether or not absorbable | Standalone sterile catgut sutures, synthetic absorbable sutures, sterile hemostats, adhesion barriers used in surgical contexts (including research models mimicking surgery) | 0.0% |
| 3006.93.10.00 | Other pharmaceutical goods: Placebos and blinded (or double-blinded) clinical trial kits for a recognized clinical trial, put up in measured doses: Packaged with medicinal preparations | Research kits where the suture is packaged together with a medicinal preparation as part of a blinded/double-blinded clinical trial | 0.0% |
🔍 Critical Note on Data Source: The provided data indicates a 0.0% total tax rate for both codes. This likely reflects a specific jurisdiction (e.g., US under certain conditions, or a free trade agreement partner, or specific research exemptions). However, customs classification must always be verified with local regulations. The 0% rate suggests these items may be duty-free for medical/research imports, but duties are only one part of clearance.

| Document | Required? | Notes |
|---|---|---|
| ✅ Certificate of Sterility | ✔️ | Must confirm the product is sterile surgical grade. |
| ✅ Manufacturer’s Letter of Guarantee | ✔️ | Confirming intended use (e.g., "For Research Purposes Only, Not for Human Clinical Use") |
| ✅ FDA Regulatory Status | ✔️ | Crucial: Even for research, verify if the item requires FDA exemption (e.g., Investigational New Drug (IND) exemption if used in trials). |
| ✅ Commercial Invoice | ✔️ | Must clearly state: "Sterile Surgical Catgut Suture, HS Code 3006.10.01.00, For Research Use Only" |
| ✅ Packing List | ✔️ | Detail contents: suture size, material (catgut/synthetic), sterile status. |
| ✅ Clinical Trial Protocol (if applicable) | ✔️ | For code 3006.93.10.00, provide proof of recognized clinical trial. |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 “Sterile is Pharma, Not Textile. Research Needs Proof, FDA Checks Too!”
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Standalone Sterile Catgut | HS: 3006.10.01.00 |
❌ Declaring as "Textile Yarn" (5006/5407) → 300+ days delay, seizure |
| Research Kit with Drugs | HS: 3006.93.10.00 |
❌ Declaring as "Surgical Suture" if packaged with drugs → Misclassification |
| Non-Sterile Catgut (Lab Use) | HS: 3006.10.01.00 (if still pharma) or 5006.00.80.00 (if not sterile/surgical) |
❌ Claiming "Research" to avoid FDA without proper classification |
| Synthetic Absorbable Suture | HS: 3006.10.01.00 |
❌ Declaring as "Plastic Thread" → Incorrect Chapter |
📌 Important: Even if duty is 0%, US Customs and Border Protection (CBP) will scrutinize Chapter 30 imports for FDA compliance. Ensure the product is not intended for commercial human use unless properly approved.
✅ 3. Special Cases
| Situation | Handling Advice |
|---|---|
| Import for Academic Research | Provide a letter from the university/research institute confirming non-commercial use. |
| Import for Biomedical Industry R&D | Ensure the supplier has an FDA Establishment Registration if the product is considered a device/drug. |
| Misclassification Risk | If unsure, apply for an CBP Binding Ruling before shipment. |
| Dual-Use (Research & Clinical) | If intended for future clinical use, declare accordingly and provide FDA IND documentation. |

📌 6. Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Classifying Sterile Catgut as "Textile Thread" (Chapter 50/54) 👉 Consequence: CBP reclassifies as Chapter 30 → Duty back-pay + penalties. Sterile surgical goods are pharmaceuticals, not textiles.
❌ Mistake 2: Ignoring FDA Requirements 👉 Consequence: Seizure by FDA even if CBP clears it. Sterile catgut is a medical device/drug component.
❌ Mistake 3: Using 3006.93.10.00 for Non-Clinical Research
👉 Consequence: Misclassification. This code is only for kits packaged with medicinal preparations in recognized trials.
❌ Mistake 4: Incomplete Documentation 👉 Consequence: Customs hold for sterility certificate or research purpose proof.
✅ Correct Approach:
"Sterile Surgical Catgut Suture, 0.0mm, Absorbable, For Research Use Only, FDA-Exempt Status [if applicable], HS Code 3006.10.01.00"
🎯 7. Conclusion: Precise Classification Saves Time and Money
🎯 Remember:
🔹 "Sterile = Pharma (Chapter 30), Not Textile"
🔹 "Research Needs Proof, FDA Compliance is Key"
🔹 "0% Duty, But High Compliance Standards"
📌 Pro Tip: If your research involves human subjects, ensure you have an IRB (Institutional Review Board) approval and FDA IND exemption documentation. For in vitro research, a simple Research Use Only (RUO) statement may suffice, but confirm with your supplier’s FDA status.

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
