Ensure certificates are genuine and attached with the customs entry form. Our Import Service team validates each before export to prevent clearance delays.
How to Classify Machinery Under Correct HS Codes
U.S. Customs uses the Harmonized System (HS) for import tariffs. Proper classification prevents disputes or re-evaluation.
| Machinery Type | HS Code Example | Duty Rate | Note |
|---|---|---|---|
| Construction Equipment | 8429.40 | 2.5% | Includes excavators/loaders |
| CNC Machines | 8458.11 | 3.7% | Requires precision data sheet |
| Agricultural Equipment | 8432.80 | 2.0% | May qualify for tariff reduction |
| Electric Motors | 8501.20 | 3.4% | Needs UL certificate |

What Are Common Mistakes in Machinery Documentation?
- Missing EPA or UL certification for power-driven machinery.

- Incorrect consignee details delaying CBP clearance.
- Undeclared wood packaging violating ISPM-15 rules.
Partnering with a Door To Door logistics provider eliminates these risks through unified documentation management.
Packaging Standards and Labeling Requirements
Heavy machinery requires strong, compliant packaging to ensure safety during sea transit.
| Packaging Type | Specification | Ideal Use |
|---|---|---|
| Steel Frames | Durable for large loads | Industrial machinery |
| ISPM-15 Wooden Crates | Heat-treated wood | Exported mechanical parts |
| Foam + Plastic Lining | Shock absorption | Precision tools and motors |
Warehouse facilities in Ningbo, Guangzhou, and Shanghai provide inspection, repacking, and labeling services before shipment.
Freight Cost and Transit Time Comparison
| Shipping Type | Cost Estimate | Duration | Best For |
|---|---|---|---|
| LCL Sea Freight | $400–$600 per CBM | 30–35 days | Small machinery |
| FCL Sea Freight | $1,200–$1,800 per 40HQ | 35–40 days | Large equipment |
| Air Freight | $6–$8 per kg | 7–10 days | Urgent components |
| Break Bulk | $80–$100 per ton | 35–45 days | Oversized units |
For massive shipments, combining Break Bulk with bonded warehouse storage reduces total cost.
