Step-by-step marketplace compliance guides for global sellers.
Start with the problem you are trying to solve. XrdaGrid keeps marketplace policy, legal or regulatory requirements, and the practical document or remedy path separate, so you can open the right guide without treating every platform request as a universal rule.

Browse by compliance problem
SDS and dangerous goods
Use these guides when a marketplace asks for a Safety Data Sheet, rejects one, or you need to decide whether an existing document still fits the product.
- Use the free SDS rejection checklist — review product match, file mechanics, required sections, and listing consistency before resubmitting.
- Do I Need a New SDS? — decide whether to reuse, request, correct, revise, or commission an SDS.
- How to Fix a Rejected SDS — diagnose the rejection and try the smallest evidence-based correction first.
- Manufacturer SDS vs. Authored SDS — compare supplier documentation with a newly authored document before paying for replacement work.
- Does a Safety Data Sheet (SDS) Expire? — separate revision triggers from unsupported calendar-expiry assumptions.
- Marketplace SDS Requirements by Platform — compare how Amazon, TikTok Shop, and Walmart handle SDS requests.
FDA registration, listing, and proof
Open this group when a marketplace asks for FDA evidence or when similar registration, listing, agent, and identifier terms are being confused.
- FDA Facility Registration vs Product Listing — identify which record applies to the FDA program and product type.
- Do You Need a U.S. Agent? — compare U.S. agent roles across food, drugs, devices, and cosmetics.
- NDC vs CPLN vs FURLS — distinguish a drug identifier, a cosmetic listing number, and an FDA filing system.
- What Counts as FDA Registration Proof for Food Sellers? — choose useful marketplace evidence without treating it as an FDA certificate.
Medical devices
Start here for device classification, listing records, or an Amazon medical-device compliance appeal.
- Is a 510(k) Required or Exempt? — work from the product code, regulation, intended use, and exemption limits.
- FURLS Registration and Device Listing — understand what the FDA system, establishment registration, and device listing each show.
- Amazon Medical Device Appeal Checklist — match the ASIN and classification evidence before resubmitting an appeal.
CPSC, children’s products, and eFiling
Use these guides for CPC documents, laboratory evidence, CPSC certificate data, and the import eFiling workflow.
- CPC vs Laboratory Test Report — see who issues each document and why one does not replace the other.
- Marketplace CPC Rejection Checklist — check the certificate, product match, laboratory scope, report, and upload path.
- How to Find a CPSC-Accepted Laboratory — verify the laboratory and its scope before relying on a test report.
- CPSC eFiling Requirements for Importers — review who files, which certificate data is transmitted, and the implementation timeline.
- Product Registry vs ACE eFiling — separate certificate storage and reference workflows from import transmission.
EPA, FIFRA, and pesticide flags
Open this group when product claims or identifiers trigger a pesticide-related marketplace review.
- EPA Registration Number vs Establishment Number — distinguish the product record from the producing-establishment identifier.
- FIFRA Claims That Trigger Marketplace Flags — locate the claims that may cause Amazon or TikTok Shop to classify a listing as pesticide-related.
- Amazon Pesticide Flag: False Positive or Real Requirement? — decide whether to correct listing language or prepare actual EPA/FIFRA evidence.
Cosmetics
Use these guides to separate the responsible-person role, safety assessment, notification portal, dossier, label, and marketplace upload request.
- EU Cosmetics Responsible Person vs CPSR — distinguish the accountable role from the qualified safety assessment.
- CPNP vs SCPN Cosmetics Notification — choose the notification route for the European Union, Northern Ireland, or Great Britain.
- TikTok Shop EU Cosmetics Document Checklist — organize PIF, CPSR, notification proof, label evidence, and an SDS where applicable.
EU and EPR
Start here when a European market asks for producer registration, a representative, a PRO arrangement, reporting, or reactivation evidence.
- Authorized Representative for EPR — check when the role appears and how it differs from a PRO.
- EPR Registration Number vs PRO Fees — separate registration evidence from scheme, reporting, and service charges.
- Packaging EPR Country by Country — compare the country-level sequence before entering another European market.
- Netherlands Textile EPR Obligations for Foreign Sellers — route a non-Dutch textile seller through the Dutch producer, representation, registration, and reporting questions.
- Zalando EPR Reactivation Checklist — diagnose a restriction, reconcile registry data, and prepare a matched reactivation pack.
Marketplace documentation and brand portals
Use these guides when the immediate problem is an account, category, or brand-portal evidence request rather than a broad regulatory explanation.
- TikTok Shop Category Qualification Documents — identify the requested evidence by seller role and category, then follow the matching submission path.
- Walmart Brand Portal Trademark Requirements — review eligibility, trademark identifiers, account roles, and enrollment limits.
- Pending vs Registered Trademark for Walmart — compare the two USPTO statuses before starting Brand Portal enrollment.
Not sure where to start?
- A marketplace rejected a document: start with the relevant rejection checklist or appeal guide.
- You are unsure what two records mean: open the comparison or “versus” explainer for those exact records.
- You are deciding whether to buy a service: use the decision guide first to define the missing deliverable.
- You are ready to compare paid providers: browse the XrdaGrid provider comparisons.
How XrdaGrid verifies these guides
XrdaGrid starts with primary regulator, legal, marketplace, and provider sources. Marketplace policy is kept separate from law, mutable facts are dated, and commercial facts are checked independently. Read the methodology and editorial policy for the full standard.
Informational notice: These guides provide general marketplace-compliance information, not legal advice. Requirements can depend on product, seller role, jurisdiction, and the current marketplace workflow. Verify the current official source and obtain qualified advice for product-specific decisions.
