In today’s global trade landscape, tariff management has become a mission-critical function — especially for glass distributors and manufacturers who import raw materials, finished units, and specialized products from overseas. With frequent changes in trade regulations, duty rates, and classification codes, even a small oversight in your tariff management system can result in costly penalties, delayed shipments, and compliance risks.
Whether you’re a glass executive overseeing international procurement or a logistics manager handling customs documentation, regular audits of your tariff compliance system are non-negotiable. Below are 7 essential questions to help you evaluate the strength and reliability of your current process.
1. Are You Using the Most Accurate and Up-to-Date HS Codes?
Every imported glass product — whether it’s tempered glass panels, float glass sheets, or insulated units — must be classified using the Harmonized System (HS) codes. But these codes can be updated periodically, and misclassification is a common and costly mistake.
Ask yourself:
Are we using the correct 6-digit HS base codes and applicable 8- or 10-digit national codes for each product?
Do we regularly verify code changes from U.S. Customs and Border Protection (CBP) and the Canada Border Services Agency (CBSA)?

2. Have You Mapped Your Products to All Applicable Tariff Schedules?
Glass products often fall under multiple tariff schedules, depending on country of origin, trade agreements, or specific product characteristics (like coating or lamination). Failure to identify applicable trade programs — such as the USMCA or MFN (Most Favored Nation) rates — can lead to missed cost-saving opportunities.
Key audit points:
Are you leveraging preferential tariff treatments under USMCA or other agreements?
Have you considered duty drawbacks or exemptions for re-exported glass products?

3. How Often Do You Review Tariff Changes by Region or Country?
Tariff regulations are influenced by shifting trade policies, anti-dumping measures, and retaliatory tariffs. For example, certain glass imports from China may be subject to additional duties due to anti-dumping rulings or Section 301 tariffs in the U.S.
Ask:
Are we subscribed to real-time tariff update services or legal alerts?
Do we have a designated team or consultant reviewing changes that affect our imports from key countries?

4. Do You Maintain an Audit Trail of All Tariff Classifications and Decisions?
In case of an audit by customs authorities, being able to prove the rationale behind your classifications is essential. This includes internal notes, rulings, and correspondence with brokers or customs officers.
Audit checklist:
Are product classification decisions well documented and stored in a centralized system?
Do we retain rulings and letters from customs for at least five years?

5. Are Your Brokers and Logistics Partners Fully Aligned With Your Tariff Strategy?
Many importers rely on third-party brokers or freight forwarders to manage customs declarations. But miscommunication can result in inconsistent or incorrect tariff filings, leading to overpayment or non-compliance.
Key considerations:
Do we regularly review our customs entries for accuracy?
Are our partners using the same product descriptions and codes we’ve defined?

6. Have You Integrated Your Tariff Management System With Your ERP or Supply Chain Software?
A siloed approach to tariff management leads to inefficiencies and errors. Ideally, your classification, documentation, and compliance checks should be integrated into your enterprise resource planning (ERP) or supply chain platform.
Review:
Is our ERP updated with the latest tariff codes and duties for each SKU?
Do we have automated alerts or flags for misclassified imports?

7. What Is Your Plan for Tariff Risk Mitigation and Scenario Planning?
Tariff rates can shift overnight due to political changes, trade disputes, or emergency economic measures. Glass executives need to prepare for a range of scenarios — including sudden duty spikes or restricted access to foreign suppliers.
Risk strategy questions:
Do we run simulations to assess the financial impact of tariff changes?
Are we developing alternative sourcing strategies to reduce dependence on high-risk countries?

Final Thoughts
Auditing your tariff management system is not just about compliance — it’s a strategic lever for cost control, operational efficiency, and risk mitigation. For U.S. and Canadian glass distributors, where imports are integral to product offerings, taking a proactive approach ensures smoother customs clearance, reduced penalties, and optimized sourcing decisions.
Use these seven questions as a framework to review your current processes, identify gaps, and improve how your organization handles complex import scenarios.
