Is My E-commerce Store Compliant in USA & Europe? The Simple Guide
A short read to understand compliance needs, risks, and sanctions for stores selling to customers in the USA and Europe.
United States Federal Requirements
PCI DSS (Payment Card Industry Data Security Standard). This security standard applies to businesses handling credit card information. Compliance involves using certified payment processors, avoiding storage of full card numbers on servers, implementing SSL certificates, conducting quarterly vulnerability scans, and completing annual Self-Assessment Questionnaires.
Non-compliance risks include monthly fines ranging from $5,000–$100,000, card brand penalties of $50–$90 per compromised record, loss of credit card processing ability, and customer lawsuits.
FTC Act Section 5 (Fair Trade Practices). This regulation prohibits deceptive or unfair business practices. Stores must provide honest product descriptions, display total costs before checkout, honor advertised prices and delivery times, implement clear return policies, and avoid misleading marketing.
Violations carry civil penalties up to $51,744 per violation, injunctive relief, consumer restitution requirements, and reputation damage.
CAN-SPAM Act. Commercial email marketing must include unsubscribe links, honor opt-out requests within 10 business days, use truthful sender information and subject lines, display physical business address, and avoid deceptive headers.
Penalties reach $51,744 per email violation, with potential criminal charges, ISP domain blocking, and email deliverability damage.
State-Level Requirements
Sales Tax Collection. Businesses with sales nexus must register for state sales tax permits, calculate thresholds (typically $100K–$500K), use automated tax software, file regular returns, and maintain transaction records.
Consequences include back taxes owed with 5–25% penalties, interest charges, business license revocation, and personal owner liability.
State Privacy Laws (CCPA, CPRA, etc.). California and other states require comprehensive privacy policies, "Do Not Sell My Info" mechanisms, data deletion procedures, staff privacy training, and documented data processing records.
Fines range from $2,500–$7,500 per violation, with class action exposure of $100–$750 per consumer, regulatory investigations, and mandatory audits.
European Union Requirements
GDPR (General Data Protection Regulation). This applies to businesses serving EU customers. Requirements include obtaining explicit consent, implementing deletion procedures, conducting Data Protection Impact Assessments, appointing an EU representative if needed, and reporting breaches within 72 hours.
Violations incur fines up to €20 million or 4% of global annual revenue, plus criminal penalties, business suspension, and reputation damage.
Digital Services Act (DSA). New EU rules require content moderation systems, clear terms of service, complaint procedures, risk assessments for illegal content, and moderation activity reporting.
Penalties reach 6% of global annual turnover, periodic payments, EU business suspension, and mandatory external audits.
VAT (Value Added Tax). Businesses must register for VAT in relevant EU countries, use calculation software, issue compliant invoices, file regular returns, and maintain records for 10+ years.
Non-compliance results in unpaid VAT plus penalties up to 100%, criminal prosecution, asset seizure, and potential business closure.
Product Safety & CE Marking. Products must meet EU safety standards with required certifications, CE marking application, technical documentation, and recall procedures.
Violations trigger product recalls, fines exceeding €100,000 (varying by member state), criminal liability, and import/export restrictions.
