From China to Amazon FBA: Factory-Side Shipping Guide 2026

If you sell on Amazon US, the gap between placing an order with a Chinese supplier and seeing your inventory live in a FBA warehouse is where most headaches — and most money — get lost.

In our 15+ years operating as a factory-direct manufacturer in the sports protection and gloves category, we've shipped to hundreds of Amazon FBA sellers. We've seen the same mistakes repeated: mis-labeled cartons, mis-sized pallets, freight quotes that don't match the actual loaded weight, and factories that promise 30 days and deliver 60.

This guide walks you through the entire FBA shipping chain from a factory's perspective — what you should expect, what to demand, and where to push back.

1. Why FBA Shipping is a Different Beast

Amazon's FBA network has strict, non-negotiable rules. Three things make it different from ordinary export shipping:

• Inbound labeling is mandatory. Every carton needs a FNSKU label and an outer carton label. Wrong or missing labels = automatic refusal at the dock.
• Time-window reservations. You must book a delivery appointment with the warehouse. Walk-ins don't exist.
• Pallet and packaging standards. Amazon publishes detailed requirements on box sizes, weight limits, pallet specs (40"×48" GMA standard), and stretch wrap rules.

In short: a normal export shipment and an FBA shipment are not the same workflow. A factory that doesn't understand this is a liability.

2. Three Shipping Methods: Sea, Air, Express

💡 Factory's rule of thumb: if your order is below 1 CBM and under 200 kg, express may be the cleanest. If it's above 3 CBM, sea freight wins on cost every time.

3. FBA Prep: The Factory's Checklist (The Part Most Suppliers Get Wrong)

This is where the real work happens. Before a single box leaves our facility, here's what we run through:

1. FNSKU labeling — You can send us labels, or authorize us to print and apply. We barcode-scan every unit to catch duplicates and unreadable prints.
2. Carton labels — Outer carton label printed and applied to the correct side (Amazon specifies which).
3. Inner packaging compliance — Poly bags with suffocation warnings (US requirement), proper carton strength (Edge Crush Test ≥ 32 ECT for items over 50 lb).
4. Palletization — 40"×48" GMA standard pallets, double-stretch-wrapped, corner boards added for export. We never use weak pallets that collapse under load.
5. Shipper/Consignee markings — Shipping marks on every carton for traceability.
6. Box content documentation — Packing list, commercial invoice, and HS codes ready before pickup.

A factory that skimps on this list costs you days of detention fees at the destination port and potential FBA rejection.

4. The Five Most Common Pitfalls (We've Fixed All of These)

1. Wrong FNSKU on the wrong ASIN. A factory batch-mixes labels → entire pallet refused at Amazon dock.
2. Carton weight over 50 lb without the heavy-overweight symbol. Amazon's "Heavy Package" surcharge kicks in, and they may refuse the box.
3. Pallet overhang. Boxes hanging off the pallet edge → automatic rejection.
4. Freight quote vs. actual loaded weight mismatch. The freight forwarder bills on the higher number. Always pre-weigh with us.
5. Production delay pushing the ship date. A factory that over-promises on production time is the #1 reason Amazon sellers miss Prime Day / BFCM inventory cutoff dates.

5. How to Evaluate a Factory Partner for FBA Shipping

You should look for four non-negotiables:

1. Vertical production control. A vertically integrated manufacturer owns the production lines — not a trading company that re-sources from three different factories. This is the only way to guarantee consistent quality and on-time production.
2. BSCI or equivalent social-compliance audit. Our manufacturing facility operates under BSCI audit standards, so your goods clear the social-compliance filter that most large Amazon sellers and brand owners now require.
3. Dedicated FBA prep experience. Ask: "How many FBA shipments have you prepared in the last 12 months?" The answer should be a number, not vague reassurance.
4. Documentation discipline. Packing list, commercial invoice, HS code, and certificate of origin — all delivered with the shipment, not 5 days after.

⚠️ Watch out for suppliers who say "we can do everything" but are actually a trading company fronting as a factory. They have no control over production timing, and your FBA dates will slip.

6. Our End-to-End Process

Here's the workflow we follow with every Amazon FBA seller:

1. RFQ & sampling — Send us your tech pack or reference product. Samples in 7–10 days.
2. Pre-production meeting — Confirm packaging, labeling, and palletization specs in writing.
3. Production + inline QC + final inspection — 3 inspection points, signed off before any carton is packed.
4. FBA prep — FNSKU applied, cartons labeled, palletized, shrink-wrapped.
5. Loading & export — We load at our facility, hand to your nominated freight forwarder (or recommend one if you need), and provide the Bill of Lading, packing list, and commercial invoice.
6. Post-shipment — We share the B/L within 24 hours of vessel departure. If Amazon asks for documentation, we respond same day.

FAQ

Q: How long does it take to ship from China to Amazon FBA?
A: Sea freight 25–35 days, air 7–12 days, express 3–7 days. Add 2–3 days for customs clearance and FBA warehouse booking.

Q: Should I use FCL or LCL for my first Amazon shipment?
A: If your order fills more than 15 CBM, FCL is almost always cheaper per unit. Below that, LCL is more cost-effective.

Q: Can the factory apply FNSKU labels?
A: Yes — we recommend it. It cuts the prep step and reduces the risk of mis-labeling at a third-party prep house.

Q: What's the most common reason FBA shipments get rejected?
A: Labeling errors (FNSKU, carton, pallet) account for over 60% of rejections. This is a factory-side problem, not a freight problem.
