Top 3 Questions About Customs Data
Many exporters have questions when using customs data, such as:
⢠Why is data from some countries incomplete? ⢠Why do some companies have no contact information? ⢠Whatâs the difference between customs data platforms?
Here are the 3 most common questions explained briefly.
1ď¸âŁ Why is customs data incomplete in some countries?
Customs data comes from official disclosures by each countryâs customs authority, and transparency policies vary widely.
Generally, countries fall into three categories:
Fully open â Countries like the United States, India, Vietnam, and Brazil publish detailed shipment records, including company names.
Partially open â Some countries only publish trade statistics (HS codes, values, partner countries) without company details.
Not open â Due to privacy or policy restrictions, some countries do not release enterprise-level trade data at all.
So when some platforms claim â200+ countries coverage,â it doesnât always mean all countries have real company-level data. Some datasets are only estimated from partner-country records.
2ď¸âŁ Why do some companies have no phone or email?
This is another common question.
In many countries, contact information is not a required field on bills of lading, so some shipment records simply donât include emails or phone numbers.
