🧪 Water-Based Chlorinated Adhesive (WBCA)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 Part I: Product Definition & Classification – Do You Really Understand “Chlorinated Adhesive”?
Water-based chlorinated adhesive is a specialized chemical bonding agent used primarily in industrial applications such as casting, molding, and high-speed industrial assembly. In international trade, its classification depends heavily on its chemical composition, functional purpose, and state of preparation.
Key distinctions: - Is it a raw polymer? If the product is primarily a chlorinated polymer in primary form (not yet mixed with solvents, catalysts, or fillers), it falls under Chapter 39 (Plastics). - Is it a formulated adhesive? If the product is pre-mixed, activated, or designed for immediate use (e.g., fast-curing or mold-specific), it may fall under Chapter 35 (Albuminoidal substances; Glues) or Chapter 38 (Miscellaneous chemical products).
⚠️ Critical Distinction Point:
- If the product is a polymer resin intended for further processing → HS 3901.90.90.00
- If the product contains vinyl chloride copolymers → HS 3901.30.20.00
- If the product is a prepared binder for casting → HS 3824.10.00.00
- If the product is a fast-curing prepared adhesive → HS 3506.91.50.00 or 3506.99.00.00
📦 Part II: HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
| HS Code | Product Description | Applicable Scenario | Key Characteristic |
|---|---|---|---|
3901.90.90.00 |
Chlorinated Adhesive Formula: Main component is chlorinated polymer, classified as “Other primary forms of ethylene polymers” | Raw polymer resins, intermediate chemicals | ✅ Polymer Base |
3901.30.20.00 |
Chlorinated Adhesive Formula: Contains vinyl chloride, classified as “Primary forms of ethylene-vinyl acetate-vinyl chloride copolymers” | Copolymer-based adhesives | ✅ Copolymer Base |
3824.10.00.00 |
Chlorinated Adhesive Formula: Designed for mold or core preparation, reflects “prepared” characteristic | Foundry binders, molding agents | ✅ Prepared Binder |
3506.91.50.00 |
Fast-Curing Chlorinated Adhesive: Classified as “Prepared adhesives, polymeric base” | Industrial fast-bonding applications | ✅ Prepared Adhesive |
3506.99.00.00 |
Fast-Curing Chlorinated Adhesive: Classified as “Other prepared adhesives” | General-purpose prepared glues | ✅ Prepared Adhesive |
🔍 Key Reminder:
- Products labeled as “formula” or “prepared” must not be misclassified as raw polymers if they contain additives that alter their chemical nature for immediate use. - Chapter 35 products are typically ready-to-use, while Chapter 39 products are raw materials for further manufacturing. - Misclassification can lead to severe tariff penalties due to differing duty rates.
💰 Part III: 2026 Latest Tariff Rate Breakdown (Including Surtaxes & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)

| De Minimis Eligibility | ❌ Not Eligible (deny_de_minimis) |
| Legal Path | Base: 6.5% → Section 301: +25% → IEEPA: +10% |
📌 Explanation:
- This classification applies to raw chlorinated polymer resins. - Despite being a “chemical,” it is treated as a plastic product (Chapter 39), attracting significant additional tariffs. - 41.5% is a high-cost barrier for exporters.
🎯 2. 3901.30.20.00 —— Ethylene-Vinyl Acetate-Vinyl Chloride Copolymer
| Item | Content |

🛠️ Part IV: Customs Clearance Practical Advice (Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (All Mandatory)
| Document | Mandatory | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must include composition, active ingredients, curing time, viscosity |
| ✅ Formula/Composition Ratio | ✔️ | Critical for determining if it’s “prepared” vs. “raw polymer” |
| ✅ Product Photos (Label & Packaging) | ✔️ | Show MSDS label, hazard symbols, brand, model |
| ✅ Third-Party Lab Report | ✔️ | MSDS, REACH, or equivalent safety data sheets |
| ✅ Commercial Invoice | ✔️ | Must clearly state “Water-Based Chlorinated Adhesive, Prepared” or “Chlorinated Polymer Resin” |
| ✅ Certificate of Origin (CO) | ✔️ | Required for tariff calculation; if not China-origin, may qualify for lower rates |
| ✅ Packing List | ✔️ | Detail net/gross weight, quantity, and packaging type |
✅ 2. Declaration Tips (Key Mantra)
🔥 “Prepared vs. Raw: Declare the Function, Not Just the Name!”
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Raw polymer resin | 3901.90.90.00 |
Mislabeling as “adhesive” → Audit risk |
| Foundry binder | 3824.10.00.00 |
Declaring as “general glue” → Wrong classification |
| Fast-curing glue | 3506.91.50.00 |
Declaring as “polymer” → Higher duty (41.5% vs 37.1%) |
| Generic prepared glue | 3506.99.00.00 |
Over-specifying as “fast-curing” without proof |
📌 Pro Tip:
- Use terms like “Prepared Adhesive” or “Formulated Binder” in the description to justify Chapter 35/38 classification. - Avoid vague terms like “Glue” or “Chemical” without context.
✅ 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Adhesive | Provide customer specs + safety data sheet to prove “prepared” status |
| Adhesive with Solvents | If >50% solvent, may reclassify under Chapter 38 (other chemicals) |
| Water-Based Claim | Must provide MSDS showing water as primary carrier, not solvent |
| Mixed Chemicals | If multiple active ingredients, consult a customs broker for final ruling |
🌍 Part V: Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Total Duty (China Origin) | Certification Required | Notes |
|---|---|---|---|---|

📌 Conclusion:
- USA is the most expensive market for chlorinated adhesives due to Section 301 and IEEPA tariffs. - EU and Japan offer more favorable conditions for prepared adhesives. - Consider supply chain diversification if exporting to the US at scale.
📌 Part VI: Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Declaring “Prepared Adhesive” as “Raw Polymer”
👉 Consequence: Higher duty (41.5% vs 37.1%) + audit risk
❌ Error 2: Misclassifying “Foundry Binder” as “General Glue”
👉 Consequence: Wrong HS code, potential fines for misdeclaration
❌ Error 3: Omitting MSDS or Composition Details
👉 Consequence: Customs holds shipment for verification → Delays + storage fees
❌ Error 4: Using “Glue” without specifying “Prepared” or “Raw”
👉 Consequence: Ambiguous classification, customs may choose highest applicable rate
✅ Correct Practice:
“Water-Based Fast-Curing Chlorinated Adhesive, Pre-Formulated, Polymeric Base, MSDS Available, Model XYZ”
🎯 Part VII: Conclusion – Precise Classification Saves Money!
🎯 Remember the Mantra:
🔹 “Prepared vs. Raw: Choose Chapter 35/38, Not 39!”
🔹 “Base Rate 2.1% vs 6.5%: Small Difference, Big Savings!”
🔹 “Always Include MSDS: Avoid Customs Delays!”
📌 Pro Tip:
If your adhesive is manufactured in Vietnam, Mexico, or Thailand, you may avoid Section 301 surtaxes, reducing total duty to 0-6.5%.
Recommend pre-advance ruling with US Customs (CBP) to confirm HS code eligibility.

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
