🧴 Water Glass Glue (Sodium Silicate Adhesives)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Water Glass Glue"?
"Water Glass Glue," technically known as Sodium Silicate or Potassium Silicate solutions, is a widely used inorganic adhesive. It is transparent, odorless, and hardens when it loses water or reacts with CO₂. In international trade, its classification depends heavily on its physical state, packaging size, and specific additives.
⚠️ Key Distinction Points:
- If the product is a caulking compound (paste/mastic form for sealing gaps), it falls under Heading 3214.
- If the product is a pure adhesive put up for retail sale in containers ≤ 1 kg, it falls under Heading 3506.
- If the product is a pure adhesive put up in containers > 1 kg (industrial bulk), or not specified for retail, it typically falls under Heading 3506.99.
📦 II. HS Code Classification Details (Based on Provided Data)
| HS Code | Product Description | Application Scenario | Packaging Condition |
|---|---|---|---|
3506.10.50.00 |
Prepared glues suitable for retail sale as adhesives, net weight ≤ 1 kg: Other | Small bottles of water glass glue sold in craft stores, hardware retail | ✅ ≤ 1 kg, Retail Ready |
3506.99.00.00 |
Other prepared glues and adhesives (not elsewhere specified) | Industrial drums, bulk containers, or retail packages > 1 kg | ❌ > 1 kg or Non-Retail Specific |
3214.10.00.10 |
Caulking compounds (mastics for sealing/gluing) | Paste form used for window sealing, joint filling, or construction sealing | ✅ Mastic/Paste Form |
3214.90.50.00 |
Other preparations for filling cracks, gaps, etc. (not putty/filler/caulking) | Specialized industrial adhesives not fitting other specific headings | ❌ General Industrial Use |
🔍 Critical Note:
- Retail Packaging is Key: If your "Water Glass Glue" is sold in small bottles (e.g., 500ml craft glue) labeled for home/DIY use, aim for 3506.10.50.00.
- Form Matters: If it is a thick paste used for sealing windows or joints, classify as Caulking Compound (3214.10.00.10).
- Bulk/Industrial: If sold in 5-gallon buckets or industrial drums, it likely falls under 3506.99.00.00 or 3214.90.50.00.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025–2026 (Current Trade Rules)
🎯 1. 3506.10.50.00 —— Prepared Glues for Retail Sale (≤ 1 kg)
| Item | Content |
|---|---|
| Base Tariff | 0% (Ad Valorem) |
| Section 301 Surtax | 0% (Exempt from major 301 tariffs) |
| IEEPA Surcharge | 0% |
| Total Tariff | 0.0% |
| Tax Calculation | CIF Value × 0% = $0 |
| De Minimis Eligible? | ✅ Yes (If value ≤ $800, can enter via Section 321 without duty) |
| Legal Basis | HTSUS:3506.10.50.00 → USITC Footnote: Exempt |
📌 Explanation:
- This code benefits from zero duty for most countries, including China, under current trade policies for specific retail adhesives.
- Major Advantage: Low cost entry, high competitiveness for small-packaged consumer goods.
🎯 2. 3506.99.00.00 —— Other Prepared Glues (Industrial/Bulk)
| Item | Content |
|---|---|
| Base Tariff | 2.1% |
| Section 301 Surtax | 25% (Standard 301 tariff on Chinese origin goods) |
| IEEPA Surcharge | 0% (Assumed included in 301 base unless specified otherwise) |
| Total Tariff | 27.1% |
| Tax Calculation | CIF Value × 27.1% |
| De Minimis Eligible? | ❌ No (High duty rates often trigger stricter scrutiny) |
| Legal Basis | HTSUS:3506.99.00.00 → USITC Footnote: 301 Tariff Applies |
📌 Note:
- This is the "catch-all" for adhesives not meeting the strict "retail ≤1kg" criteria.
- The 25% surtax significantly increases costs for industrial buyers.
🎯 3. 3214.10.00.10 —— Caulking Compounds (Sealing Mastics)
| Item | Content |
|---|---|

| De Minimis Eligible? | ✅ Yes |
| Legal Basis | HTSUS:3214.10.00.10 → Exempt Category |
📌 Explanation:
- If your product is formulated as a sealing mastic (e.g., for construction joints), it enjoys zero duty.
- Ensure the product description emphasizes "Caulking," "Sealing," or "Mastic" rather than just "Glue."
🎯 4. 3214.90.50.00 —— Other Preparations for Filling/Sealing
| Item | Content |
|---|---|
| Base Tariff | 3.25% |

- Industrial bulk shipments face 27-28% tariffs, so consider local packaging or value-add processing abroad.
📌 VI. Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Declaring bulk industrial silicate as retail glue
👉 Result: Customs audit, seizure, or 27.1% retroactive duty.
👉 Fix: Accurately declare net weight and packaging type.
❌ Mistake 2: Confusing "Glue" with "Caulking Compound"
👉 Result: Misclassification. If it’s a paste for sealing, use 3214.
👉 Fix: Check product consistency and intended use.
❌ Mistake 3: Ignoring SDS/Chemical Safety
👉 Result: Customs holds shipment for chemical review.
👉 Fix: Submit complete SDS with HS Code application.
🎯 VII. Conclusion: Smart Classification, Maximized Profit!
🎯 Remember the Key Rules:
🔹 “≤ 1 kg Retail? → 3506.10.50.00 (0% Duty)”
🔹 “Sealing Paste? → 3214.10.00.10 (0% Duty)”
🔹 “Bulk/Industrial? → 3506.99.00.00 (27.1% Duty)”
🔹 “Other Sealants? → 3214.90.50.00 (28.25% Duty)”
📌 Pro Tip:
For small businesses or e-commerce sellers, focus on retail packaging (≤ 1 kg) and highlight "Craft/Decorative Use" in descriptions to qualify for 0% duty.
For industrial suppliers, evaluate if local packaging in the US is cost-effective to avoid high tariffs.
📣 Action Item:
📞 Verify product weight and packaging with your supplier.
📄 Prepare SDS and clear product photos.
📝 Choose the correct HS Code before shipping to avoid delays.

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
