NASP

The North American Selection Policy (NASP) outlines the rules and eligibility criteria for listing products across Amazon's NA marketplaces: Amazon.com (U.S.), Amazon.ca (Canada), and Amazon.com.mx (Mexico). It is particularly relevant to sellers using programs like NAFN (North American Fulfilment Network) and NARF (North American Remote Fulfilment).

Key factors covered by NASP:

• Product eligibility across borders (e.g., size, weight, category restrictions)
• Compliance with local regulations (e.g., language, safety, labeling)
• Import/export limitations (e.g., hazmat, batteries, supplements)
• Requirements for localized listing content (currency, language, units)
• Restrictions on certain ASINs in Canada or Mexico that may be allowed in the U.S.

Why NASP matters for sellers:

• Determines whether an ASIN listed in the U.S. can be auto-listed in Canada or Mexico
• Affects inventory eligibility for cross-border fulfillment through NARF
• Ensures sellers remain compliant with local laws and marketplace rules
• Helps reduce rejections, suppressed listings, and border clearance issues

💡 Example: A U.S. seller lists a topical cream that complies with FDA regulations, but NASP blocks it from being auto-listed on Amazon.ca due to Canadian health product restrictions.

In short:
NASP (North American Selection Policy) defines which products can be listed and sold across Amazon’s North American marketplaces - ensuring cross-border listings meet compliance, safety, and localization requirements.
