International Marketplace Compliance: The Complete Guide for Global E-commerce Sellers

Expanding your business beyond borders can be one of the most powerful growth strategies in e-commerce. Marketplaces like Amazon, Walmart, eBay, Etsy, and Shopify give sellers access to millions of international customers — but with that opportunity comes a crucial responsibility: compliance.

From tax laws and product labeling to customs paperwork and data privacy, international marketplace compliance is more than just a legal requirement — it’s the foundation for building trust, avoiding penalties, and scaling your brand globally.

In this comprehensive guide, AMZ Northland breaks down everything you need to know to stay compliant while selling on international marketplaces.

1. What Is International Marketplace Compliance?

International marketplace compliance refers to the laws, regulations, and platform policies that sellers must follow when selling products across borders. These requirements vary from country to country and often include:

• Tax and business registration
•  Customs documentation and import/export rules
•  Product safety standards and certifications
•  Labeling and language requirements
•  Data privacy and consumer protection laws
•  Marketplace-specific policies and listing standards

Compliance ensures that your business operates legally, builds credibility with customers, and avoids costly delays, penalties, or account suspensions.

2. Business & Tax Registration Requirements

Before selling internationally, you must register your business and meet tax obligations in each target market.

🇺🇸 United States

• EIN (Employer Identification Number): Required for U.S. tax filing.
• Sales Tax Nexus: You may need to collect sales tax if you store inventory in the U.S. or exceed certain sales thresholds.
• State-Specific Laws: Each state may have different tax rules.

🇨🇦 Canada

• Business Number (BN): Required for tax registration.
• GST/HST: Mandatory if annual sales exceed CAD $30,000.
• Import Number: If you ship products directly to Canadian customers.

🇪🇺 European Union

• VAT Registration: Required in the country where goods are stored or sold.
• IOSS (Import One-Stop Shop): Simplifies VAT collection for orders under €150.

Pro Tip: Partner with a tax specialist who understands multi-country compliance — mistakes can lead to audits, fines, or account suspensions.

3. Customs, Tariffs & Import Regulations

Customs and import laws vary by country but usually require proper documentation and declarations.

Key Documents:

• Commercial Invoice: Declares product details, value, and HS codes.
• Packing List: Helps customs authorities verify shipment contents.
• Certificate of Origin: Required for preferential trade agreements (like USMCA or EU FTAs).

Tariffs & Duties:

• Rates depend on product classification (HS code), origin, and value.
• Some products may qualify for duty-free trade under trade agreements.
• Non-compliance can result in delays, seizures, or fines.

Tip: Always classify your products correctly and include accurate HS codes and valuations.

4. Product Safety, Labeling & Packaging Requirements

Every country has strict rules regarding product safety, labeling, and packaging. Failure to meet these standards can lead to rejected shipments, recalls, or legal penalties.

Common Requirements:

• Safety Certifications: CE (EU), FCC (USA), CSA (Canada), etc.
• Bilingual Labels: For example, Canada requires English and French.
• Country of Origin: Must clearly state where the product is made.
• Measurement Units: Metric system in Canada/EU, imperial in the USA.
• Warning Labels: Certain products (e.g., chemicals, electronics, toys) require safety warnings.

Pro Tip: Always review category-specific compliance requirements — cosmetics, food, and electronics have stricter rules than apparel or home goods.

5. Marketplace-Specific Compliance Policies

Each marketplace has its own rules and seller requirements. Violating them can lead to product removal or account suspension.

Amazon

• Follow product category restrictions and obtain necessary approvals.
• Ensure product listings meet A+ content and image requirements.
• Comply with country-specific tax and invoicing laws.

Walmart Marketplace

• Meet U.S. and Canadian import, labeling, and tax rules.
• Provide accurate product data and UPC/EAN codes.

eBay & Etsy

• Clearly state shipping locations, return policies, and customs charges.
• Accurately describe products and disclose materials or certifications.

Tip: Always read marketplace seller agreements and stay updated on policy changes.

6. Data Privacy & Consumer Protection Compliance

As you expand globally, you’ll also collect more customer data — and must follow privacy laws in every country you operate.

• GDPR (EU): Requires explicit customer consent and data handling transparency.
• PIPEDA (Canada): Governs data use and storage for Canadian customers.
• CCPA (California, USA): Gives consumers control over their personal information.

Best Practice: Always have a clear privacy policy, obtain consent before collecting data, and secure all customer information.

7. Strategies to Stay Compliant and Protect Your Business

Navigating international regulations can be complex, but these strategies will help you stay on track:

• Work With Experts: Hire customs brokers, tax consultants, or compliance agencies.
• Automate Compliance: Use software for VAT, tax collection, and customs documentation.
• Train Your Team: Make sure your team understands labeling, listing, and shipping requirements.
• Audit Regularly: Conduct regular compliance audits to prevent issues before they occur.
