Your First Amazon FBA Shipment from Taiwan: A Complete Step-by-Step Guide

Every unit you send to an Amazon FBA warehouse must have an FNSKU (Fulfillment Network Stock Keeping Unit) label applied to the outside of each individual unit's packaging. The FNSKU is Amazon's internal barcode that identifies your specific seller's product — it is different from the ASIN (which identifies the product in Amazon's catalog) and from a standard UPC barcode. Generate FNSKU labels in Seller Central under Inventory → Manage Inventory → click the product → Print Item Labels. Labels must be 1" x 2" minimum, printed in black and white, scannable, and not placed over any existing barcode on the packaging.

Amazon's packaging requirements for FBA inbound shipments are detailed in the FBA Inventory Requirements Help page in Seller Central, and non-compliance results in shipment rejection or additional prep fees (USD 1.50–2.50 per unit charged to your account). Key requirements: products must be packaged securely so they can withstand the rigors of automated fulfillment (conveyor belts, robotic sorting) without damage. Loose or fragile items must be individually packaged. Items that could spill, leak, or puncture must be sealed in secondary packaging. Products that are themselves bags or pouches must have a suffocation warning label on any plastic bag with an opening larger than 5 inches.

Poly bag requirements are strictly enforced. All products sold as poly-bagged items must use bags of at least 1.5 mil thickness. The bag must be transparent. Any poly bag with an opening larger than 5 inches in any direction must have a suffocation warning printed in 10-point font or larger on the outside of the bag: "WARNING: To avoid danger of suffocation, keep this plastic bag away from babies and children. Do not use this bag in cribs, beds, carriages or playpens." Pre-printed poly bags with this warning are available from Amazon-approved suppliers on Alibaba for approximately USD 0.02–0.05 per bag.

Carton requirements for FBA inbound shipments: each carton must weigh no more than 50 pounds (22.7 kg) and must not exceed 25 inches (63.5 cm) on any single side — unless the contents are an oversized item that qualifies for single-item-per-box shipment. Cartons must be sturdy corrugated cardboard (single-wall minimum for cartons up to 20 lbs, double-wall for heavier cartons). Each carton must have a carton label printed from your FBA shipment plan in Seller Central affixed on one side, covering any existing barcodes or labels from a previous shipment. Use a 4" x 6" label for standard cartons.

Navigate to Inventory → Send/Replenish Inventory (or the newer "Send to Amazon" workflow depending on your Seller Central interface version). Select the products and quantities you are shipping. Amazon's system assigns your shipment to one or more fulfillment centers based on the product category, destination marketplace, and available warehouse capacity — you cannot choose the specific warehouse yourself. First-time shippers frequently discover their shipment is split into 2–4 different FBA locations across multiple states; this is normal and not negotiable under Amazon's standard workflow.

The Send to Amazon workflow asks you to specify the box contents: how many units of each SKU are in each carton, the dimensions and weight of each carton, and whether you are using Amazon-partnered carrier services or your own freight forwarder for inbound transportation. For shipments from Taiwan, you will use "Non-Amazon carrier" (your own freight forwarder) rather than Amazon's partnered carrier program, which only applies to domestic US shipments. Enter your carton dimensions and weights accurately — inaccurate measurements result in additional charges assessed after delivery when Amazon re-measures your cartons.

Print the carton labels directly from the shipment plan after confirming box content details. Each carton gets a unique label with a barcode that tells Amazon's receiving system exactly which shipment this carton belongs to and what it should contain. Apply the carton label to the longest flat side of the carton, with no folds, tears, or placement over seams. Labels must be clearly scannable and not obscured by strapping tape. For large shipments of 50+ cartons, organize cartons by destination fulfillment center and attach a packing list to the first carton of each destination group.

Confirm the shipment plan and record the FBA Shipment ID numbers generated for each destination. Your freight forwarder needs these shipment IDs to create the Bill of Lading (BOL) and to notify Amazon of the incoming delivery. Amazon requires an Advance Shipment Notification (ASN) — essentially your shipment plan serves as the ASN when created in Seller Central. However, your freight forwarder must also book a delivery appointment at each receiving warehouse through Amazon's Carrier Central portal (carrier.amazon.com) before the delivery driver can unload. Deliveries without appointments are rejected at the dock.

Your freight forwarder handles US customs clearance on your behalf as part of their door-to-door FBA service. Ensure your commercial invoice accurately states: the correct HTS (Harmonized Tariff Schedule) code for each product, the accurate per-unit value (not an artificially low value — US CBP actively scrutinizes undervalued invoices from China and Taiwan), the full description of the merchandise, country of origin (Taiwan), and your US importer of record information. Provide your freight forwarder with a complete packing list that matches your carton contents exactly as entered in your Amazon shipment plan.

The commercial invoice value determines your US import duties. Common mistakes that cause customs delays: using FOB Taiwan price on the invoice but forgetting to include tooling amortization costs (which CBP may add back), describing products with generic terms ("electronic goods") instead of specific descriptions that match the HTS classification, or mis-classifying products in a lower-duty HTS code that doesn't accurately describe the merchandise. CBP has the authority to detain and re-examine shipments at the port, causing delays of 1–4 weeks and potential re-delivery fees to the Amazon fulfillment center.

After customs clearance, your freight forwarder's delivery agent contacts each Amazon fulfillment center to book the required delivery appointment through Carrier Central. Amazon allocates delivery appointments on a first-come, first-served basis; during peak periods (September–November before Q4), appointment slots can be booked out 1–3 weeks in advance. Coordinate with your freight forwarder to book appointments immediately after customs clearance rather than waiting for the physical delivery truck to arrive at the port area.

Once the delivery truck arrives at the Amazon fulfillment center with your appointment, Amazon's receiving team unloads, scans, and processes your cartons. The time from physical delivery to inventory appearing as "available" in Seller Central typically ranges from 3–10 business days for standard-size products. You can track receiving progress in Seller Central under Inventory → Manage FBA Shipments → click your shipment ID → Shipment Contents. Do not create a removal order or raise a receiving dispute until at least 10 business days have passed since confirmed delivery.

The most frequent first-shipment mistake is using the product's UPC barcode instead of the FNSKU barcode on each unit. If your product has both a UPC and an FNSKU label, the FNSKU must completely cover the UPC or be the only scannable barcode visible on the unit. Amazon's warehouse scanners default to scanning the FNSKU; if the scanner picks up the UPC instead, your units get received into the wrong inventory pool or rejected entirely. Print FNSKU labels on opaque white label stock and apply them completely over any UPC that appears on the product packaging.

Sending mixed SKUs in the same carton without declaring them in the shipment plan causes receiving delays and potential unexpected prep fees. Each carton should ideally contain only one SKU. If you must mix SKUs in a carton (for multi-variation products), declare the exact contents in the shipment plan's box content section. Amazon's receiving team will not individually sort or count unmarked mixed-SKU cartons — they will quarantine the carton and charge a manual processing fee of USD 0.15 per unit plus a USD 10–25 carton processing fee.

Carton weight exceeding 50 pounds is a common problem with high-density products like ceramics, metal tools, or heavy appliances. Repack these products into smaller cartons before shipping — never attempt to ship a carton over 50 lbs to Amazon FBA. Amazon's dock workers and conveyor systems are not designed for overweight cartons, and cartons that are too heavy or too large are refused at the dock. If your product is inherently heavy (e.g., a 30-lb kitchen appliance), each unit goes in its own carton with appropriate heavy-item handling labels ("Team Lift Required" at 50+ lbs, "Mechanical Lift Required" at 100+ lbs).

First-time shippers consistently underestimate receiving time and create their Amazon listing expecting inventory to be available for sale within 3–4 days of delivery. The realistic timeline from Taiwan factory gate to Amazon "available" inventory is 35–55 days for sea freight: 3–5 days inland to Taiwan port + 14–21 days ocean transit to US West Coast + 3–7 days port drayage and customs clearance + 1–3 days inland to Amazon warehouse + 3–10 days Amazon receiving. Build this full timeline into your inventory planning, especially for launch shipments where you want stock available on your listing go-live date.
