The issue of filling Amazon FBA stock out of China is a fine line to walk–do it correctly and you will not run out of stock, reduce expenses and improve your seller performance. Lack of proper planning conversely results in emergency air shipments that appear to eat margins or bare shelves that lose the Buy Box. Our services, which include sourcing and inspections, warehousing and logistics, have simplified this to a million sellers at BM Supply Chain. Our China-based set up provides tailor-made services such as sourcing raw materials or finished products, 30 days of free storage, state of the art warehouse, free API docking to ship easily and one-stop tracking of goods to ease up cash flow, whereby you concentrate on growth and we handle the details.
The success of the replenishment is determined by demand prediction, China stock buffering, prep, and clever shipping decisions. This eliminates the risk of overstock charges in FBA (such as long-term storage costs such as 3.63 per cubic foot 271-365 days) and provides stable income. By 2026, when Amazon will terminate in-house prep, it will rely on a sound China workflow to remain compliant and efficient.
In the absence of a system, the sellers will be squandering money in quick freight or disposing of unsold inventory. In China, proximity offers fast solutions and it is the smart place to be in terms of replenishing.

- Forecast based on sales data.
- Buffer in China warehouse.
- Inspect quality.

How to Replenish Inventory Effectively
The workflow of replenishment in China begins with the production in your supplier at the location, and then go to a nearby warehouse to perform buffering and prep before being shipped to FBA warehouses. Major stages: Forecast to determine amounts, check and prepare to be ready, choose freight to end up with speed and cost, and monitor to be sure of arrival on time.
Being able to plan ahead schedules out of stock products incurred by lost sales and lost positions, and can prevent excessive replacement, which saves FBA storage costs. Make data-driven decisions with the help of such tools as Seller Central analytics.

Unsystemed sellers are likely to pay an exaggerated price on express delivery or there will be some type of emergency. It is done through a systematic method and in particular the use of China warehouses to maintain low costs and inventory.

Forecast Inventory Based on Sales Demand
Begin with data – Reexamine historical sales in Seller Central, including seasonality such as highs in Q4 or Prime Day. The SKUs that sell fast require a higher safety stock (20-30% buffer) to meet the lead times in China which may take 20-40 days by sea.
Wrong forecasting? You hurry deliveries of air, which is more expensive, or run out of stock, which is detrimental to metrics. Know the restock of Amazon limits- according to sales velocity not to overstock.
Pro tips: Trends with tools such as Jungle Scout; 30-60 days in FBA. Our API-integrated forecasts have assisted our clients in reducing emergency by 50 percent.
Keep Buffer Inventory in a China Warehouse
In China, buffer stock is a kind of safety net-have extra inventory that goes into stock after production, and is not linked to FBA space.
Why ideal? Cheap relative to U.S.–we offer 30 days of free warehousing where you can stock and stage your inventory, and order only what you need on-demand. This evades FBA penalties of slow-movers in long term storage.
Stops Amazon overstocking, where charges are high in Q4. Here before FBA send, consolidate with numerous suppliers, e.g.
Conduct Quality Inspection Before Replenishing

Check in China to identify defects at an early stage such as wrong colors, missing parts or damage, before the expensive shipping.
Avoids FBA rejection and returns, which slap your score. On-site repairs are less expensive because they are conducted at close proximity to factories.
Checks the accuracy of preps, such as labelling. In BM Supply Chain, 90% of problems are caught through our QC which cuts the returns made by clients by 25%.
Complete FBA Prep in China
Prep is productive here, label fragile with bubble wrap, label soft items with warning labels on the poly bag, label sets with Sold as Set labels, and label cartons properly.
Why cheaper/faster? Lower labor, bulk materials. Do not prep U.S. premiums after 2026.
We deal with end to end, meaning that we comply to reduce delays.
Choose the Best Shipping Method for Replenishment

Select based on urgency and volume.
Air Freight (For urgent replenishment)
5-10 days, reliable for restocks. Most suitable in high-velocity goods–stable and more expensive.
Sea Freight (For heavy or planned replenishment)
20-40 days, cost-efficient for bulk. See big with small LCL, big with small FCL plan ahead.
Express Couriers (For small restock quantities)
3-7 days through DHL/UPS, ideal to use on samples and also expensive.
DDP Shipping (Most popular for Amazon sellers)
All-including, duty paid -air/sea variants. Foreseeable, makes traditions easier–best to the majority.
Recommendation: Sea planned, air alerts–factor lead times.
Create Amazon FBA Inbound Shipment Accurately
Enters carton information, such as dimensions and weights, in Seller Central to make correct plans.
Create box labels, ship contents to prevent holds. Check twice to avoid error in labelling.
This is in accordance to FBA regulations, haste check-in.
Use API Integration for Faster Replenishment

APIs automatic synchronization-alert low stock, real-time inventory update.
Rapid compared to manual- integrate with our WMS to ensure smooth alerts, avoiding emergencies.
More efficient prediction through linked tools.
Track Shipment Progress Closely
Follow through forwarder tools or our one-stop queries – China departure to FBA arrival.
Alert on delays; adjust plans. Keep levels through scheduling of check in (1-2 weeks average).
Maintain a Replenishment Calendar
Arrange weekly/bi weekly according to velocity– more frequent with fast-sellers.
Predict sales such as Prime Day–3-4 months of inventory before.
Simple illustration: Week 1: Forecast/review. Week 2: Order/inspect. Week 3: Prep/ship. Week 4: Track/arrive.
Do not work at the last minute.
Avoid Common Replenishment Mistakes
- Shipping late: Stockouts–predict well.
- Shipping excessively: Warehouse charges–apply buffers.
- Carton size wrong: Rejections–check compliant.
- Missing labels: Holds- check twice.
- Supplier prep mistake- Use 3PL.
