🏗️ Frame Rods / Structural Supports (Jianjia Gan)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly Are "Frame Rods"?
"Frame Rods" (框架杆) is a generic term in Chinese manufacturing and construction, typically referring to structural supports used in scaffolding, formwork, furniture assembly, or industrial frameworks. Because the term describes a shape/function rather than a specific material, customs classification is entirely dependent on the material composition and specific application.
In international trade, this item is ambiguous. If declared vaguely as "Metal Rods" or "Plastic Sticks," it risks significant customs delays or misclassification penalties. It must be classified based on the raw material.
⚠️ Key Distinction Point:
- If made of Plastics/Polymers with longitudinal irregularities (e.g., rods, bars) → Section 39
- If made of Iron/Steel used for construction support (e.g., scaffolding props) → Section 73
- If made of Wood used for concrete formwork support → Section 44
📦 II. HS Code Classification Details (2026 Latest Tariff Authoritative Comparison)
Based on the provided data, there are 5 possible classifications depending on the material. Below is the detailed breakdown:
| HS Code | Material Type | Product Description | Summary of Classification Logic | Total Tax Rate (China→US) |
|---|---|---|---|---|
3916.90.50.00 |
Plastics | Plastic rods/bars (other) | Based on morphology matching (rods) and plastic material inference. | 40.8% |
3916.10.00.00 |
Polymers | Rods, bars, sticks of plastics | Based on morphology matching and plastic/polymer material inference. | 40.8% |
7308.90.30.00 |
Steel/Metal | Structural components of iron/steel | Inferred as metal or steel structural parts based on shape and use. | 85.0% |
7308.90.95.90 |
Steel/Iron | Steel structural parts | Inferred as steel structural parts based on morphological features. | 85.0% |
4418.30.01.00 |
Wood | Wooden structural support components | Inferred as wooden building support components based on morphology and use. | 38.2% |
🔍 Critical Reminder:
- "Frame Rods" cannot be declared without specifying the material.
- Plastic vs. Steel: Plastic rods are significantly cheaper to import (40.8%) compared to steel structural components (85.0%) due to high punitive tariffs on steel.
- Wood: Wooden formwork props fall under a different chapter with a lower but still substantial tax burden (38.2%).

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)
✅ 1. Document Checklist (Non-negotiable)
| Document | Required | Note |
|---|---|---|
| ✅ Material Certificate | ✔️ | Must explicitly state if the rod is Steel, Plastic, or Wood. "Frame Rod" is insufficient. |
| ✅ Product Photos | ✔️ | Show the cross-section and surface texture to prove material type. |
| ✅ Technical Data Sheet | ✔️ | Specify dimensions, tensile strength, and coating (if any). |
| ✅ Commercial Invoice | ✔️ | Use the exact material in the description (e.g., "Steel Scaffolding Prop" not just "Frame Rod"). |
| ✅ Packing List | ✔️ | Ensure weight and quantity match the HS code declaration. |
✅ 2. Declaration Strategy (Key Mantra)
🔥 "Material First, Shape Second, Name Specific, Tax Determined!"
| Scenario | Correct Declaration | Incorrect Declaration | Consequence |
|---|---|---|---|
| Steel Scaffolding Pole | 7308.90.95.90 (Steel Structural Part) |
"Metal Pipe" or "Iron Rod" | Risk of 85% tax + penalty for misclassification |
| Plastic Formwork Rod | 3916.90.50.00 or 3916.10.00.00 |
"Construction Support" | Risk of 40.8% tax (correct) but delay if material unclear |
| Wooden Formwork Prop | 4418.30.01.00 (Wooden Support) |
"Wooden Stick" | Risk of 38.2% tax + duty adjustment |
✅ 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| Steel Rods with Plastic Coating | If the coating is minor, it may still be classified as Steel (85.0%). If the plastic layer is structural, argue for Plastic (40.8%), but provide evidence. |
| Aluminum Frame Rods | If the material is Aluminum, it also falls under Section 232 → 85.0%. Same as steel! |
| Composite Materials | If made of mixed materials, classification becomes complex. Seek a Binding Ruling from CBP before shipment. |
| Small Plastic Parts | Even small plastic "rods" fall under Section 39. No exemption for small size if intended for construction/industrial use. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Notes |
|---|---|---|---|
| 🇺🇸 USA | Varies by Material | 38.2% ~ 85.0% | High punitive tariffs. Steel/Aluminum are most expensive. |
| 🇪🇺 EU | Varies by Material | 0% ~ 6.5% | No Section 301/232 equivalents. Lower cost, but VAT applies. |
| 🇨🇳 China | Varies by Material | 0% ~ 5% | Export duty is low or zero. Focus on destination country tariffs. |
| 🇻🇳 Vietnam | Varies by Material | 0% ~ 10% | If shipped from Vietnam, may avoid US punitive tariffs. |
📌 Conclusion:
- USA Market is Highly Sensitive: Steel/Aluminum "Frame Rods" face an 85% total tariff. Plastic and Wood are cheaper but still costly (38-41%).
- Strategic Advice: If shipping to the US, consider shifting sourcing to Southeast Asia (Vietnam, Thailand) to avoid Section 301/232 tariffs.
📌 VI. Common Errors & Pitfalls (Lessons from Blood & Tears)
❌ Error 1: Declaring "Steel Rods" as "Plastic Parts"
👉 Consequence: Customs inspection reveals steel → 85% tax + fraud penalty + seizure.
❌ Error 2: Declaring "Frame Rods" without material specification
👉 Consequence: Customs assigns the worst-case scenario (usually Steel/85%) or holds the shipment for clarification → Delays & Storage Fees.
❌ Error 3: Ignoring Section 232 for Aluminum
👉 Consequence: Aluminum frame rods are also subject to 50% Section 232 tariff. Total 85%. Many importers forget this!
❌ Error 4: Using "Construction Support" as HS Code
👉 Consequence: Vague description → Customs rejection or manual classification delay.
✅ Correct Practice:
"Steel Scaffolding Prop, 1.5m, 48mm Dia, Hot-Dipped Galvanized, Model ABC, Origin China"
→ Declared under7308.90.95.90with 85.0% duty.
🎯 VII. Conclusion: Precision Classification Saves Millions!
🎯 Remember the Mantra:
🔹 "Material Dictates Code, Code Dictates Tax!"
🔹 "Steel & Aluminum: 85%! Plastic & Wood: ~40%! Declare Clearly!"
🔹 "Don't Guess, Verify! Pre-ruling is your best friend!"
📌 Pro Tip:
If you are importing Steel or Aluminum Frame Rods to the US, the 85% tariff may make the business model unprofitable.
- Action: Explore sourcing from Vietnam/Mexico (avoiding China origin).

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
