For e-commerce brands sourcing products from China and selling to US customers, the fulfillment location is one of the most important decisions in the supply chain.
The decision also matters because online sales volume keeps growing. According to the U.S. Census Bureau’s quarterly retail e-commerce data, U.S. retail ecommerce sales reached $326.7 billion in the first quarter of 2026 on a seasonally adjusted basis.
A China fulfillment centre will maintain stock near the factories and suppliers. A US fulfillment center locates inventory nearer to its American customers. Both models are viable, but they address different problems.
The best option will depend on your product, sales, margin, expected delivery, cash flow and stage of growth. Some brands should be fulfilled in China. The others should shift the inventories to the US. A hybrid approach is needed for many emerging DTC brands.
This article presents a comparison of the China fulfillment center and the US fulfillment center, which could help you make a decision about which fulfillment center model is suitable for your company.
The key question is not simply “China or the US?” The better question is which products should stay close to suppliers, which products should move closer to customers, and when a hybrid model makes more sense.
Quick Comparison
| Factor | China Fulfillment Center | US Fulfillment Center |
| Best for | Product testing, long-tail SKUs, flexible inventory | Proven best sellers, strong US demand, faster delivery |
| Inventory location | Near suppliers and factories | Near US customers |
| Upfront inventory commitment | Lower | Higher |
| Delivery speed to US customers | Usually slower | Usually faster |
| Storage cost exposure | Often lower | Often higher |
| Returns handling | More difficult for US customers | Easier with a domestic return address |
| Product testing | Strong | Less flexible if the stock must move in bulk |
| Best strategy | Test, launch, and manage uncertain SKUs | Scale proven products with predictable demand |
Neither choice is necessarily best—flexibility with a China fulfillment center. US Fulfillment Center provides speed. The optimal fulfillment approach can be a combination of using each location for the products that are best served by it.
What Is a China Fulfillment Center?
A China fulfillment center is a warehouse within the Chinese nation that receives products from suppliers, stores, picks and packs orders, and ships them to the customer.
This can help to minimize unnecessary movement for brands manufacturing in China. The brand will no longer have to send all goods to the US for sale; products will be stored nearer to the factory and orders placed internationally will be sent from China. A China fulfillment center may support:
- Inventory receiving from suppliers
- Product inspection
- SKU labeling
- Kitting and assembly
- Custom packaging
- Direct international shipping
- Crowdfunding order fulfillment
- Product testing before bulk overseas storage
This is used where the need is not known. A brand can try out new products, sell them to different countries and not warehouse too many of each SKU in the USA prematurely.
China fulfillment is additionally beneficial for brands that have plenty of product variations. For instance, a supplier might have a number of different colours, sizes, bundles or combinations of accessories. If only a small number of the variations sell regularly, then it doesn’t make sense to store all of these versions in the US.
The disadvantage is that it takes time to deliver. Shipping from China to the USA normally takes longer than shipping from a USA warehouse. It may include more intricate tracking, customs issues, and returns management, as well.
What Is a US Fulfillment Center?
A US fulfillment center keeps products within the United States and fulfills orders to American customers.
This can help brands that sell in the US a lot, as it can lead to faster deliveries and better customer experience. The customer doesn’t have to wait for all orders to be shipped across borders; rather, the package is shipped from a domestic warehouse.
A US fulfillment center may support:
- Domestic storage
- Pick and pack
- Faster local shipping
- Returns processing
- Marketplace fulfillment support
- Regional inventory placement
- Lower shipping zones for nearby customers
- Better delivery predictability
US fulfillment is best when there is already an established demand. A brand should be aware of the products that sell, how fast they move and if the product margins can be adjusted for the storage and fulfillment costs that will be incurred in the domestic market.
The U.S. parcel market is large and competitive. Pitney Bowes reported that 23.1 billion parcels were shipped in the United States in 2025, which shows why delivery speed, cost, and warehouse location matter for brands selling to American customers.
In exchange, there is an inventory commitment. In order for the brand to ship orders out of a US fulfillment center, they need to first transfer inventory to the US. That includes paying for bulk freight, customs clearance, receiving, storage and inventory prior to the sale of these units.
Cost Differences
China’s fulfillment center might appear to be less expensive on the surface, as the brand does not have to pay for bulk freight into the US and does not have to hold all of the SKUs in the US. This can safeguard cash flow, particularly for new products.
But, when order volumes increase or products are heavy, bulky, and/or low-margin, international shipping from China on a per-order basis can get costly.
Stocking a US fulfillment centre might be more expensive as there’s a need to import stock beforehand. Seller may send products abroad, pay for import customs formalities and warehouse receiving and storage prior to receipt of customer orders.
Once products are in the US, though, domestic shipping might be quicker and cheaper for American buyers. This is particularly true if orders are limited to the US and the product has regular sales.
The correct comparison is not “which warehouse is cheaper.” The better question is:
Which model creates the best profit per delivered order?
That calculation should include:
- Product cost
- Freight cost
- Customs duties
- Warehouse receiving
- Storage fees
- Pick-and-pack fees
- Packaging
- Domestic or international shipping
- Returns
- Refund risk
- Customer support workload
- Inventory that may not sell
A China fulfillment center can be cheaper for uncertain demand. A US fulfillment center can be better for proven demand. The numbers depend on the SKU.
Delivery Speed and Customer Experience
Delivery speed is one of the biggest differences between China and US fulfillment.
Americans have a specific expectation for shipping and delivery dates, tracking, and quick delivery. For the American customer, it’s frequently the case that a U.S. fulfillment center can offer a better customer experience since the order is already in the country.
China fulfillment is perfectly possible, as long as customers have realistic time expectations. It’s risky if sellers claim they will deliver quickly but use international shipping routes that take longer.
A practical rule is simple:
- Use China fulfillment when flexibility matters more than speed.
- Use US fulfillment when delivery speed affects conversion, reviews, or repeat purchases.
For instance, a brand new gadget that’s being tested with paid advertising campaigns can begin in China. When the product has good demand in the USA, the seller can transfer the inventory to a US warehouse to facilitate delivery. This will make sure that the brand doesn’t over-commit too early, yet still enhance service when requested.
Inventory Risk and Cash Flow
Inventory risk is often the hidden part of the decision.
By having China fulfill, the brand can keep inventory near its suppliers and take its time. It is helpful for products whose demand is not certain, new products, seasonal testing, and long-tail products.
The brand has to predict demand when making importations for U.S. fulfillment. An inaccurate prediction might result in excess inventory in an expensive warehouse, or it could result in having insufficient inventory to satisfy demand.
US fulfillment can also result in sending more inventory than is required because of the time it takes for replenishment. When demand decreases, brands may overstock so as not to run out, which results in paying storage fees.
China fulfillment offers greater flexibility with slower delivery. US fulfillment offers a faster delivery with a greater inventory commitment.
This is why many brands don’t go with a single model for the whole catalog. They should make a decision based on the SKU.
Returns and After-Sales Support
Returning is simpler with a US fulfillment center. American customers can return products to a domestic address and the warehouse can inspect, restock, quarantine, dispose of, or consolidate returned products.
For DTC brands, it is an important issue as it impacts customer trust. The international return process could be challenging, which could deter customers from returning to the business.
Returning to China fulfillment is still an option, but it is typically less convenient for U.S. customers. It may not be cost-effective to return products overseas for low-cost goods. It may be necessary for the seller to provide refunds, replacement or collection of domestic returns via another partner.
Some products that have a high return rate, sizing problems, fragile components or quality issues can be better suited for US fulfillment once proven demand. The domestic returns process provides the seller with better visibility into product problems and stock recovery.
Compliance and Import Planning
The inventory must go to the United States to fulfill orders of the U.S. customer in a U.S. fulfillment center. That means that the sellers must make some arrangements for customs documentation, customs duty, customs classification, and importer of record responsibilities.
According to U.S. Customs and Border Protection, the trade community and CBP share responsibility for compliance with import requirements. For brands moving inventory into a US fulfillment center, documentation should not be treated as a last-minute task when goods are already at the port.
Less bulk import planning is required at the start since orders might be sent individually to customers via China fulfillment. But brands must also be aware of regulations, product bans, duties and carrier requirements in the country they are shipping to.
This is particularly critical for regulated product categories, such as electronics, cosmetics, batteries, supplements, toys, and other sensitive products.
In both models, compliance should be part of the fulfillment plan, not an afterthought.
When China Fulfillment Makes More Sense
China fulfillment may be the better option when:
- You are testing a new product.
- You manufacture or source products in China.
- US demand is not yet predictable.
- You sell to several countries.
- You have many low-volume variations.
- You want to avoid high domestic storage costs.
- Your product is small, light, and suitable for international parcel shipping.
- You are running a crowdfunding or pre-launch campaign.
- You need kitting, packaging, or preparation near suppliers.
This model is especially useful when the brand wants flexibility. It allows sellers to learn what customers actually buy before committing to large overseas inventory movements.
When US Fulfillment Makes More Sense
US fulfillment may be the better option when:
- Most customers are in the United States.
- A product has consistent sales volume.
- Delivery speed affects conversion.
- You want easier domestic returns.
- The product has enough margin to support US storage.
- Shipping directly from China is causing complaints.
- Marketplace performance depends on faster delivery.
- You want clearer tracking and local carrier options.
- You are scaling paid advertising in the US.
A US fulfillment center is strongest for proven best sellers, not every SKU in the catalog. Slow movers and test products may still belong in China.
Why Hybrid Fulfillment Is Often the Best Answer
The optimal solution for many eCommerce brands isn’t China fulfillment or US fulfillment. It is both.
With hybrid fulfillment, flexible inventory is stored in China, while products that have proven demand in the U.S. are stored at the U.S. fulfillment center.
A practical hybrid setup may look like this:
| Product Type | Best Location | Reason |
| New product test | China | Avoids early US overstock risk |
| Slow-moving variation | China | Reduces domestic storage exposure |
| Best-selling SKU | US | Improves delivery speed for key market |
| Crowdfunding reward | China first, then the US if demand grows | Supports flexible launch fulfillment |
| High-return product | US after demand is proven | Easier returns and inspection |
| Backup inventory | China | Supports replenishment without overstocking locally |
This model provides sellers with more control. They can test products from China, import the winners to the United States and still maintain an inventory of long tail products close to suppliers.
The key is data. Sales velocity, margin, delivery expectations, and replenishment timing should factor into the relative movement of products.
How NextSmartShip Supports China-US Fulfillment Decisions
For brands sourcing from China and selling to the United States, the right fulfillment strategy may involve more than one warehouse location. Some SKUs may need to stay close to suppliers, while proven products may need to move closer to American customers.
NextSmartShip’s China fulfillment center can support product testing, long-tail SKUs, crowdfunding fulfillment, and direct shipping from China. This can help brands stay flexible while demand is still uncertain.
For products with stronger demand in the United States, NextSmartShip’s USA fulfillment center network can help brands place inventory closer to American customers, improve delivery speed, and support domestic fulfillment needs.
NextSmartShip’s eCommerce fulfillment services can also help connect inventory management, order processing, packing, shipping, and tracking into a more organized fulfillment workflow.
The goal is not to place every SKU in the same warehouse. The better approach is to match each product with the fulfillment location that best supports cost, speed, and customer experience.
Conclusion
Whether you select a China fulfillment center or a US fulfillment center will depend on the needs of your brand.
China fulfillment can provide versatile services, less initial stock and good support for Chinese product sources. It is appropriate for testing, early growth and long-tail inventory, as well as for international selling.
US fulfillment provides quicker delivery to the US, hassle-free returns and an enhanced customer experience for American customers. It is most effective for products whose US demand is known and that have sufficient margin to allow for US storage.
When it comes to investing in technology, hybrid is the savviest route for many brands. Retain China’s less clear and slower-moving products. Take bestsellers to the US when the need is known. Look at the decision based on SKU and not the catalog.
No guesswork when it comes to fulfillment location. It should be derived from sales figures, landed cost, delivery expectations and customer experience.
