Customs clearance is one of the most complex and costly parts of international trade. Importers often face problems such as incorrect HS codes, unexpected duties, shipment delays, or customs inspections, simply because they lack reliable, centralized information.
Fiowind provides a set of customs intelligence tools designed to help importers make the right decisions before shipping — not after problems occur.
This page serves as a central guide (anchor page) explaining how to use Fiowind to:
- Identify the correct HS / HTS code
- Calculate customs duties and additional tariffs
- Understand country-specific risks (such as China-origin imports)
- Prepare compliant customs documentation
If you import goods into the United States or other major markets, this page is your starting point.
1. Step One: Start with the Fiowind Dashboard
👉 Fiowind Dashboard

The Fiowind dashboard is the entry point for all customs-related research. From here, you can explore:
- HS / HTS classifications
- Country-to-country duty comparisons
- Product-specific import references
- Tariff and trade-measure insights
Use the dashboard when:
- You are unsure which HS/HTS code applies
- Your product could fall under multiple classifications
- You need an overview before confirming costs

2. Step Two: Calculate Customs Duty and Tariffs
👉 Customs Duty Rates Tool

Once a potential HS/HTS code is identified, the next critical step is to calculate actual duty liability, not just the base rate.
The Customs Duty Rates tool allows you to:
- Select HS / HTS codes
- Choose country of origin
- View estimated duties, including additional trade measures
- Forecast landed costs before shipping
This step helps prevent one of the most common importer mistakes: discovering extra duties only after the shipment arrives.

3. Step Three: Identify Country-Specific Import Risks
Customs duties are not applied equally across all countries. The same product can face very different tariffs depending on origin.
For example:
- Imports from China may be subject to additional trade tariffs
- Other origins may qualify for preferential duty treatment
Fiowind helps you compare these scenarios before choosing suppliers or shipping routes.

4. Step Four: Apply Product-Specific Import Logic
HS codes and duties are not purely theoretical — they depend on how a product is constructed and used.
Fiowind supports product-level analysis, such as:
- Vacuum insulated tumblers
- Stainless steel products
- Plastic containers
- Glass articles
Each product category has its own classification logic and duty implications.

5. Step Five: Prepare for Customs Clearance
Once classification and duty estimates are confirmed, you can prepare accurate customs documentation:
- Commercial invoice with correct HS/HTS code
- Clear product descriptions aligned with classification logic
- Duty expectations aligned with Fiowind estimates

✔ Customs delays
✔ Classification disputes
✔ Unexpected duty bills
