🏗️ Construction Grade Materials: HS Code Classification & Customs Clearance Guide
🌐 HS Code Reference & Customs Strategy | 2026 Latest Tariff Analysis | Professional Entry Guide
📌 1. Product Definition & Classification: What Exactly Is "Construction Grade"?
"Construction Grade" is not a single product but a category encompassing various materials used in building structures, infrastructure, and civil engineering. In international trade, these goods are strictly categorized based on their material composition (iron/steel, plastic, cement/concrete) and preparation for use.
⚠️ Critical Distinction:
- Prepared Structural Units: Components specifically shaped or prepared for assembly (e.g., beams, columns, bridge sections) → Chapter 73 (Iron/Steel) or Chapter 68 (Cement/Concrete).
- Finished Builders’ Ware: Non-structural elements like doors, windows, or generic blocks → Chapter 39 (Plastics) or Chapter 68 (Cement).
- Prefabricated Buildings: Excluded from most structural codes; look to Heading 9406 (but note: the provided data excludes these).
📦 2. HS Code Classification Details (Based on Provided Data)
| HS Code | Product Description | Key Characteristics | Application Scenario |
|---|---|---|---|
7308.90.95.90 |
Structures of iron/steel (Other) | Non-specific steel structures, excluding prefabs | General steel frameworks, custom structures |
7308.90.60.00 |
Structural Units of Iron/Steel | Columns, pillars, posts, beams, girders | Load-bearing steel components, I-beams, H-beams |
3925.90.00.00 |
Builders' Ware of Plastics (Other) | Generic plastic construction materials | Non-specified plastic building parts |
3925.20.00.20 |
Doors/Windows Frames of Plastic | Plastic doors, windows, and frames | PVC windows, aluminum-plastic composite frames |
6810.11.00.70 |
Cement/Concrete Blocks & Bricks | Building blocks, bricks (Other) | Standard concrete masonry units, decorative blocks |
6810.91.00.00 |
Prefabricated Structural Components of Cement/Concrete | Prefab concrete elements for building/civil engineering | Precast concrete panels, beams, tunnel segments |
🔍 Key Note:
- Steel Structures (7308...) are heavily taxed due to trade restrictions.
- Plastic Builders' Ware (3925...) has lower or zero tariffs, except for specific items like windows.
- Cement/Concrete (6810...) varies: generic bricks are tax-free, but prefabricated components face a 25% surcharge.
💰 3. 2026 Tariff Rate Breakdown (Including Surtaxes)
✅ Applicable Countries: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: 2025-11-10 onwards
🎯 1. Iron & Steel Structures (7308.90.95.90 & 7308.90.60.00)
| Item | Details |
|---|---|
| Base Tariff | 0.0% |
| Surtax | +25% (Section 301) |
| Additional Surtax | +50% (Steel, Aluminum, Copper Products Surtax) |
| Total Tax Rate | 75.0% |
| Tax Calculation | CIF Value × 75% |
| De Minimis Exemption | ❌ Not Applicable |
| Legal Basis | Steel/Aluminum/Copper Surtax: 50% + Section 301: 25% |
📌 Explanation:
- Steel construction materials face the highest combined tariff (75%).
- This includes both generic steel structures (7308.90.95.90) and specific structural units like beams/columns (7308.90.60.00).
- Cost Impact: Extremely high. Must be factored into pricing strategy.
🎯 2. Prefabricated Concrete Components (6810.91.00.00)
| Item | Details |
|---|---|
| Base Tariff | 0.0% |
| Surtax | +25% (Section 301) |
| Total Tax Rate | 25.0% |
| Tax Calculation | CIF Value × 25% |
| De Minimis Exemption | ❌ Not Applicable |
| Legal Basis | Section 301 Footnote |
📌 Note:
- Unlike generic bricks, prefabricated structural components (e.g., precast beams, panels) incur a 25% tariff.
- Ensure product description clearly states "prefabricated structural component" to avoid misclassification.
🎯 3. Plastic Builders' Ware: Doors & Windows (3925.20.00.20)
| Item | Details |
|---|---|
| Base Tariff | 5.3% |
| Surtax | +7.5% |
| Total Tax Rate | 12.8% |
| Tax Calculation | CIF Value × 12.8% |
| De Minimis Exemption | ❌ Not Applicable |
| Legal Basis | Standard USITC Tariff + Surcharge |
📌 Note:
- Plastic doors and windows have a moderate tax burden.
- Generic plastic builders' ware (3925.90.00.00) is 0%, so precise classification is critical.
🎯 4. Tax-Free Items: Generic Steel Structures? No. Generic Bricks? Yes.
| HS Code | Total Tax Rate | Notes |
|---|---|---|
3925.90.00.00 |
0.0% | Generic plastic builders' ware (not doors/windows) |
6810.11.00.70 |
0.0% | Generic cement/concrete blocks & bricks |
📌 Opportunity:
- If your product is a generic brick or non-specific plastic building part, it may be duty-free.
- Avoid labeling generic bricks as "prefabricated structural components" to maintain 0% rate.
🛠️ 4. Customs Clearance Practical Advice
✅ 1. Documentation Checklist
| Document | Required | Purpose |
|---|---|---|
| Product Specification Sheet | ✔️ | Define material, dimensions, preparation level |
| Technical Drawing | ✔️ | Show if item is "prepared for use" (e.g., drilled holes, cut shapes) |
| Commercial Invoice | ✔️ | Clearly state HS Code and product description |
| Packing List | ✔️ | Separate structural units from accessories |
| Certificate of Origin | ✔️ | Verify CN origin to apply correct surtaxes |
| Pre-Fabrication Proof | ✔️ | For concrete/steel, prove if "prefabricated" or "generic" |
✅ 2. Classification Tips
| Scenario | Correct HS Code | Incorrect HS Code | Risk |
|---|---|---|---|
| Steel beam with cut ends | 7308.90.60.00 |
7308.90.95.90 |
Both 75%, but specific code preferred |
| PVC Window Frame | 3925.20.00.20 |
3925.90.00.00 |
12.8% vs 0% → 12.8% extra cost |
| Concrete Block (generic) | 6810.11.00.70 |
6810.91.00.00 |
0% vs 25% → 25% extra cost |
| Prefabricated Concrete Panel | 6810.91.00.00 |
6810.11.00.70 |
25% vs 0% → 25% extra cost |
🔥 Golden Rule:
"Prepared for Use" = Structural Code (Higher Tax). "Generic" = Non-Structural Code (Lower/Zero Tax).
✅ 3. Special Cases
| Case | Recommendation |
|---|---|
| Mixed Containers | Separate steel, plastic, and concrete in documentation to avoid blanket high taxation |
| OEM Steel Structures | Provide engineering drawings to prove "prepared for use" |
| Plastic Windows with Aluminum Parts | If >50% plastic by weight/value, still 3925.20.00.20; otherwise, reconsider material classification |
| Prefabricated Buildings (Heading 9406) | Excluded from this data; verify separately as they may have different treatments |

📌 6. Common Mistakes & Pitfalls
❌ Mistake 1: Classifying "prefabricated concrete beams" as "generic bricks"
👉 Consequence: 25% tax evasion risk + penalties if caught.
❌ Mistake 2: Labeling "plastic window frames" as "generic plastic builders' ware"
👉 Consequence: 12.8% tax underpaid → Customs audit + back taxes.
❌ Mistake 3: Assuming all steel structures are taxed the same
👉 Consequence: Misclassification leads to delays, even if rate is same.
❌ Mistake 4: Ignoring "Prepared for Use" criteria
👉 Consequence: Generic items shipped as "prepared" may still face 0% if correctly classified, but errors can trigger audits.
✅ Correct Practice:
"Steel H-Beam, 10m Length, Cut to Size, Prepared for Structural Assembly, Model XYZ, CN Origin"
🎯 7. Conclusion: Precision Classification Saves Money!
🎯 Key Takeaways:
🔹 Steel Structures: 75% Tax → Avoid or Price Accordingly
🔹 Concrete Prefabs: 25% Tax → Justify Generic If Possible
🔹 Plastic Windows: 12.8% Tax → Acceptable Cost
🔹 Generic Bricks/Plastics: 0% Tax → Maximize Savings
📌 Pro Tip:
If your steel structures are shipped from Vietnam, Mexico, or Thailand, check for IEEPA Exemptions to reduce tariffs significantly.
Consider Advance Rulings for complex items like mixed-material structures.

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
