USPS Blocking China Parcels? Why "Zone Injection" is Your Only Safe Route in 2026

The headlines are alarming for any e-commerce seller sourcing from Asia: "USPS Suspends Inbound International Mail from China."

Whether it is due to the STOP Act, capacity constraints, or tightening customs crackdowns, the result is the same: The traditional "Direct Mail" model (ePacket, EMS, Direct International Parcels) is becoming unreliable. If you are relying on slapping a shipping label in Shenzhen and hoping it scans in Chicago, your supply chain is in danger.

But there is a loophole—or rather, a smarter logistics model—that remains wide open.

It’s called Zone Injection (or "US Warehouse Injection").
At Forest Leopard, we don't rely on the unstable international postal network. Instead, we use our physical warehouses in Brooklyn, NY and Azusa, CA to turn your international shipments into domestic US packages. Here is how it works and why it completely bypasses the current bans.

The Problem: Why "Direct Mail" is Failing

To understand the solution, you must understand why USPS stops these packages.

When you ship via "Direct Mail" (e.g., ePacket), the package enters the US through an International Mail Facility (IMF). These facilities are currently overwhelmed. US Customs (CBP) is targeting these individual small parcels for rigorous inspection regarding counterfeit goods and fentanyl, leading to massive delays and blanket suspensions.

The Fatal Flaw: You are relying on the international arm of USPS, which is the part currently under fire.

The Solution: Forest Leopard's "Zone Injection" Model

We don't hand your packages to USPS in China. We hand them to USPS in America.

By using "Zone Injection," we change the legal status of your shipment from "International Mail" to "General Air Freight" followed by "Domestic First-Class Mail."

 

How It Works (The 4-Step Process)

1. Bulk Consolidation (China):

We collect your 500 individual orders at our Shenzhen or Yiwu warehouse. Instead of sending 500 small packets, we consolidate them into one Air Cargo Pallet.

2. Customs Clearance (Type 86):

We fly this pallet to JFK (New York) or LAX (Los Angeles). We clear customs electronically using Section 321 Type 86.se legal Section 321 entry. To understand the new strict compliance rules for this, read our guide on [The Section 321 Crackdown].

l Crucial Point: The goods are legally cleared into the US before USPS ever touches them.

3. The "Injection" (Our US Warehouses):We truck the pallet to our local hubs:

• West Coast: 1344 West Foothill Blvd, Azusa, CA.
• East Coast: 180 N 8th St, Brooklyn, NY.Here, we break down the pallet and separate the individual parcels.

4. Final Mile Delivery (Domestic):We hand the parcels to the local USPS hub.

The Result: USPS sees a package originating from Brooklyn, NY, not Shenzhen, CN. They process it as a standard domestic shipment with 2-3 day delivery.

Why There is No Conflict with Section 321

Some merchants worry: "If you ship in bulk, do I lose my $800 duty-free exemption?"

The answer is No. 

Under Type 86 Entry regulations, even if we ship a container with 5,000 orders, we can legally manifest them as 5,000 individual shipments destined for 5,000 different US consumers.

• As long as each final package is under $800 value.
• As long as the "Ultimate Consignee" is the US buyer.

Forest Leopard’s IT system handles this complex data declaration for you. We provide the speed of bulk freight with the tax benefits of individual parcels.

Comparison: Old Way vs. The Forest Leopard Way

Strategic Advantage: The "Brooklyn" Factor

Most Chinese forwarders only have a warehouse in Los Angeles.Forest Leopard has a strategic hub in Brooklyn, New York.

If your customer is in Miami or Boston, shipping from LA takes 5 days by truck. By injecting your cargo directly into our Brooklyn hub, we cut that delivery time to 1-2 days. You aren't just bypassing the ban; you are beating your competitors on speed.

Conclusion: Adapt or Get Stuck

The era of cheap, slow, direct-from-China mail is ending. The restrictions from USPS are likely to get tighter, not looser.

Don't let your business be a casualty of postal politics. Switch to a Freight + Injection model. It is fully compliant, faster, and gives you total control over your inventory.
