Shipping from China
Weight & value: each vial of peptide (e.g. a 5 mg semaglutide vial) weighs well under 250 g and is declared at less than $800, so it clears U.S. Customs duty-free under Section 321 / Entry Type 86.
Transit time window:
- Best-case: 7 days
- Average: 12 days
- Maximum: 21 days
Who touches the box:
- Factory courier in China
- Export freight forwarder (YunExpress, 4PX, Yanwen, etc.)
- U.S. shipping partner / postal consolidator (ACI Logistix, UniUni, DHL eCommerce, etc.)
- Domestic carrier — usually USPS, but sometimes FedEx Ground Economy, UPS Mail Innovations or DHL eCommerce
- Your regular mail carrier
Step-by-step example — “Semaglutide Vial” to Austin, TX (12 days total)​
| # | Supplier checkpoint | What happens to the pen | Typical day |
|---|---|---|---|
| 1 | Factory shipment | Courier collects sealed cartons from the GMP facility in Shenzhen. | 0 |
| 2 | Arrival at freight forwarder | Parcels are weighed and labelled at YunExpress export hub. | 0 |
| 3 | Forwarder dispatches | Thousands of small parcels (including the pen) are palletised for the daily dedicated-line flight. | 0 |

| 5 | Export by Chinese Customs | One electronic manifest covers the whole pallet; clearance takes minutes. | 0 evening |
| 6 | Arrange flight | Space booked on an overnight HKG → LAX cargo flight. | 0 night |
| 7 | Flight departure | Aircraft lifts off just after midnight. | 1 |
| 8 | Flight arrival | Lands at LAX roughly 12 hours later. | 1 |
| 9 | Waiting for U.S. clearance | Pre-filed data lets CBP auto-release while the pallet sits in bond. | 1 |
| 10 | Start customs clearance | Automated green light under Section 321. | 1–2 |
| 11 | Clearance complete | Pallet released to ACI Logistix truck. | 2 |
| 12 | Waiting for scanning / collection | ACI unloads at its Fontana, CA hub; tracking shows “Arrived Shipping Partner Facility – USPS Awaiting Item.” | 2–3 |

During peak weeks or major holidays, steps 12–14 can extend the journey to the 21-day maximum.
Carrier mix in the U.S. leg​
| Service booked in China | Stateside path | Last-mile carrier |
|---|---|---|
| Dedicated-line Parcel | USPS Ground Advantage label (prefix 39) | USPS |
| FedEx Ground Economy (ex-SmartPost) | Entirely FedEx network | FedEx driver |
| UPS Mail Innovations | UPS transports middle-mile, then hands to USPS (or finishes as UPS Ground Saver) | USPS / UPS |
| DHL eCommerce | DHL sort hub → USPS | USPS |
Tip: If tracking is stuck on “USPS Awaiting Item” for more than five days after the first U.S. scan, open a ticket with the shipping partner named in tracking (ACI, UniUni, DHL eCommerce, etc.). They are responsible for injecting the sack into the carrier network.
How to track every step​
| Leg | Best tool | Why |
|---|---|---|
| China export + flight | ParcelsApp.com with the original China ID (YT…, LP…, etc.) | Shows airline departure and arrival events. |
| Partner hub → carrier | ParcelsApp.com automatically switches to the U.S. shipping-partner view | Confirms when sacks leave the hub. |
| Final mile | ParcelsApp.com again — it follows the new USPS/FedEx/UPS number automatically | Live scans once the carrier accepts the parcel. |
Quick recap​
- Typical delivery for a peptide vial is 12 days, but it can be as quick as 7 days or as long as 21 days.
- “Shipping Partner – USPS Awaiting Item” means USPS has the label data but not the parcel yet.
- Watch for “Accepted at USPS facility.” After that, delivery is usually 2–5 days away.
- Shipments stay under the $800 de-minimis limit, so you do not pay U.S. duty or tax on arrival.

FAQ​
Why does my USPS tracking show Fontana, CA when it shipped from China?
Fontana is ACI Logistix’s hub. They printed your U.S. label there before the pen left Shenzhen. USPS keeps showing Fontana until ACI trucks the sack over and USPS scans “Accepted.”
Tracking shows “Shipping Partner – USPS Awaiting Item” for six days. Is it lost?
Not lost — the box is still at the partner hub. We’ll prod them; once USPS (or FedEx/UPS) scans “Accepted,” it usually reaches you within a week.
Who decides whether my package rides USPS, FedEx or UPS?
The Chinese forwarder picks a service code based on weight, destination ZIP and cost. Two orders placed minutes apart can arrive on different carriers.
Can I pay extra to speed it up?
Not right now. The dedicated-line contract keeps shipping under $5 per parcel; faster express options would triple the cost.
What if I order two pens?
As long as the combined value stays under $800 and weight under about 450 g, they follow the same 7–21-day path. Heavier multi-item orders may ride FedEx Ground Economy for the U.S. leg.
Do holidays matter?
Yes. China’s Golden Week (early October) and the U.S. Thanksgiving peak can each add 2-4 days because flights and sort hubs run at maximum load.
