Amazon FBA Sourcing Checklist: Idea to First Purchase Order

Amazon FBA sourcing is a sequence of gates. At each gate you either gain confidence or cut the product — and the expensive mistakes always trace back to a gate someone skipped. This Amazon FBA sourcing checklist covers the five phases from idea to first purchase order, with the specific questions and documents required at every step. It is deliberately blunt: if an item fails, fix it or kill the product before money moves.

Phase 1: Product validation (before you talk to any supplier)

Sourcing cannot rescue a product that should not exist. Before requesting a single quote, confirm:

• Demand evidence — sales estimates from tools like Helium 10 or Jungle Scout, plus a manual scan of top competitors' review velocity. A category where the #10 seller moves 300 units/month is an opportunity; one where only #1 survives is not.
• Margin math with real numbers — estimate landed cost (see Phase 4), Amazon referral fee (typically 15%), FBA fulfilment fee by size tier, and advertising cost of 15–25% of revenue for a launch. If your all-in margin is under 25% before ads, the product is fragile.
• Differentiation angle — what will your version improve? Bundles, size variants, material upgrades, packaging. "Same product, lower price" is a losing strategy against sellers with deeper pockets.
• Weight and size class — FBA fees jump at size-tier boundaries. Sometimes a 2 cm packaging reduction drops you a whole tier and adds 4 points of margin.

Phase 2: Supplier identification and vetting

Collect quotes from 5–8 suppliers, then verify the best two or three properly:

• Business licence check — registered capital, business scope, establishment date (full method in our factory verification guide).
• Factory vs trading company — live video of the production line, machine-specific questions. Both are workable; disguised margin is not.
• Category experience — ask for two product photos of similar items they have produced, not just catalogue shots.
• Communication quality — response time, spec comprehension, willingness to say "no" or "difficult". Suppliers who overpromise at RFQ stage overdeliver at claim stage.
• Reference checks — one call to an existing export customer per finalist.

Phase 3: Compliance and certification gates

This is where FBA sellers get burned hardest, because Amazon enforces compliance reactively — often after your inventory is already at a fulfilment centre. Confirm before the PO:

• Product-specific certification — FCC for electronics with wireless functions, CPC/ASTM F963 for children's products, FDA food-contact compliance for kitchen items, UL/ETL where category-relevant. Get the actual certificate, verify the lab, and match the certificate's model numbers to yours.
• Labelling — country-of-origin "Made in China", any warning labels for your category, and compliance marks on the product or packaging where required.
• Amazon category approval — some categories (topical, supplements, certain toys) require invoices, test reports or pre-approval. Check Seller Central requirements before production, not after.
• IP risk — run a patent/design search on the product category if it looks innovative. "The factory said it's fine" is not a defence.

Phase 4: Quotation, landed cost and packaging specification

When quotes arrive, read them correctly — most disputes come from terms nobody read. Our full method is in the quotation guide; for FBA specifically, lock these lines:

• Incoterm — FOB (Shenzhen/Ningbo) is the standard for FBA first orders; you control freight and can compare forwarders. Get EXW and FOB quoted separately to see the domestic leg's cost.
• Price validity — raw material and freight move. Fix validity at 30 days and state the quantity/price ladder for reorders.
• FBA-compliant packaging in writing — poly-bagged products requiring it (loose parts, liquids, plush), suffocation warnings on bags with 5+ inch openings, no FNSKU covering barcodes, bubble wrap for fragile items, and "Sold as set" markings for multi-packs. Amazon's prep requirements change; hand the supplier the current Seller Central prep page and confirm each item in the PI.
• Carton specification — max 50 lb (22.7 kg) per carton unless a single item exceeds it, carton dimensions and gross weight per box, master carton labels with carton x of y. Ask the supplier for a dimensional-weight calculation so you can compare sea vs air accurately.
• Sample confirmation — golden sample signed/dated by both sides, photographed, and referenced by ID in the PO. All quality arguments later resolve against this sample.

Phase 5: Production milestones and inspection

With the PO signed (30% deposit is standard for new relationships), manage the run instead of waiting for it:

• Production schedule in writing — material arrival date, line start date, completion date. Ask for a photo update at each milestone; silence is the earliest warning sign.
• During-production check (DUPRO) at ~20–30% completion for first orders — catches systematic errors while they are still cheap to fix.
• Pre-shipment inspection (PSI) at 100% production, 80% packed — AQL 2.5 major / 4.0 minor is the common default for consumer goods. The inspector needs your golden sample reference, spec sheet and FBA packaging checklist.
• Booking and labelling — FNSKU labels applied by the factory (cheaper than Amazon prep), carton marks agreed, and forwarder booked 2–3 weeks before completion for sea freight.
• Payment against inspection — 70% balance after PSI passes, before shipment release. This single term eliminates most quality disputes.

Realistic timeline and budget summary

Plan on 10–14 weeks from idea to inventory live for a first order, and treat anything faster with suspicion — timelines that skip testing and inspection are where FBA horror stories begin.
