Troubleshooting Common Issues

Issue 1: "No data found"

Possible causes:

• HS code doesn't exist for selected period
• Too restrictive filters applied
• Data not yet reported

Solutions:

• Try broader HS code (2-digit instead of 6-digit)
• Remove optional filters
• Check if data for period is available

Issue 2: "Query timeout"

Possible causes:

• Query too broad (all countries, all products)
• Server load high

Solutions:

• Narrow query scope
• Query in smaller batches
• Try during off-peak hours

Issue 3: Inconsistent values between sources

Possible causes:

• Different reporting methodologies
• Timing differences
• Data revisions

Solutions:

• Document both values with sources
• Use ranges instead of precise figures
• Check metadata for known issues
