🧪 Chemical Adhesive for Molds
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Chemical Adhesives"?
Chemical adhesives for molds are specialized bonding agents designed to join mold components, seal cavities, or repair damages in injection molding, die-casting, or compression molding setups. These adhesives often consist of polymers, rubber, or other chemical compounds that provide high heat resistance, pressure resistance, and chemical stability.
In international trade, these adhesives are categorized under Chapter 35: Albuminoidal Substances; Modified Starches; Glues; Enzymes, specifically focusing on Prepared Glues and Other Prepared Adhesives.
⚠️ Key Distinction:
- If the adhesive is based on polymers of headings 3901 to 3913 or rubber, it falls under 3506.91 or 3506.99.
- The packaging size (retail sale ≤ 1 kg vs. > 1 kg) and specific polymer type determine the exact HS Code.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Polymer/Rubber Basis | Retail Pack ≤ 1kg? |
|---|---|---|---|---|
3506.91.50.00 |
Adhesives based on polymers of headings 3901 to 3913 or on rubber: Other | Mold repair adhesives, polymer-based bonding agents | ✅ Polymers (3901-3913) or Rubber | ✅ Yes |
3506.99.00.00 |
Prepared glues and other prepared adhesives, not elsewhere specified or included: Other | General-purpose mold adhesives, non-specific polymer base | ❌ No (Other) | ✅ Yes |
🔍 Key Reminder:
-3506.91.50.00applies if the adhesive is explicitly based on specific polymers (e.g., acrylics, epoxies, polyurethanes) or rubber.
-3506.99.00.00applies if the adhesive does not fall under the specific polymer/rubber categories or is a "mixed" adhesive not specified elsewhere.
- Packaging: Both codes assume the product is put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg.

📌 Note:
- Adhesives that do not fall under the specific polymer/rubber categories are subject to a 2.1% base tariff plus a 25% Section 301 surtax, totaling 27.1%.
- This is a significant cost increase compared to3506.91.50.00.
🛠️ IV. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Required Documents Checklist (No Exception)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must detail chemical composition, polymer type, and intended use (mold adhesive). |
| ✅ MSDS/SDS (Safety Data Sheet) | ✔️ | Critical for chemical products; must specify hazards and handling instructions. |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Chemical Adhesive for Molds" and HS Code. |
| ✅ Packing List | ✔️ | Specify net weight and packaging details (must be ≤ 1 kg for retail). |
| ✅ Certificate of Origin (CO) | ✔️ | If applicable, for potential tariff benefits (though not applicable here due to US-China trade tensions). |
| ✅ Labeling Information | ✔️ | Ensure labels comply with US chemical regulations (e.g., TSCA). |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Specify Polymer, Avoid 'Other', Save 27%!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Adhesive based on epoxy resin (polymer) | 3506.91.50.00 |
Misdeclaring as 3506.99.00.00 → 27.1% tax |
| Adhesive based on rubber | 3506.91.50.00 |
Misdeclaring as 3506.99.00.00 → 27.1% tax |
| General-purpose adhesive (no specific polymer) | 3506.99.00.00 |
N/A (Correct code) |
| Packaging > 1 kg | Not covered by these codes | Misdeclaring retail pack ≤ 1 kg → Compliance risk |
✅ 3. Special Handling Cases
| Scenario | Handling Advice |
|---|---|
| OEM Custom Adhesive | Provide client order + technical data sheet to confirm polymer basis. |
| Mixed Polymer/Rubber | If both are present, consult customs broker for classification. |
| Non-Retail Packaging | If > 1 kg, consider other HS Codes (e.g., 3506.10/3506.91 for bulk). |
| Chemical Hazards | Ensure MSDS is up-to-date; non-compliance can lead to shipment rejection. |

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
