INTRODUCTION
You clicked because you need the facts before you ship CBD gummies, tinctures, or any product packed in Custom CBD Boxes in USA. This guide gives the straight answer plus steps you can take today to avoid seizure, delay, or fines.
What USPS Really Scans
USPS handles 425 million parcels daily. It does not have the staff or budget to xray every box. Instead it uses a layered risk system.
Intelligent Mail Barcodes record origin, destination, and shipper history.
Sniffer dogs trained on marijuana, hemp, and explosives walk select facilities.
Xray machines sit in only 21 national hubs. Clerks open less than 0.5 percent of packages.
Postal Inspectors flag shipments when the label lists a known drug return address, vague content like “gifts,” or when postage is paid in cash at a retail counter.
When Your Package Hits the Xray Belt
Your parcel will pass through an xray tunnel if any of the following apply.
It weighs over 13 ounces and bears stamps instead of electronic postage.
It travels Priority Mail Express, Priority Mail, or First Class Package from ZIP codes the DEA labels “hot.”
A dog alerts on the conveyor belt.
The outer box shows leakage, strong odor, or excess tape.
You ship to a PO box linked to prior seizures.
If the image shows dense organic matter shaped like vacuum sealed bricks, inspectors pull the box for a closer look.
CBD and the 0.3 Percent Rule
The 2018 Farm Bill legalized hemp derivatives, but USPS X-ray rules still treat cannabis products as restricted. You may mail hemp derived CBD within the USA when:
The product contains less than 0.3 percent THC by dry weight.
You keep the original lab report inside the outer packaging.
The mailpiece carries an internal statement of contents such as “hemp derived cannabidiol supplement, less than 0.3 percent THC.”
You use electronic postage printed through USPS, not stamps.
Shippers who ignore these steps risk seizure even if the product is federally legal.
Packaging Tactics That Pass Inspection
Custom CBD Boxes in USA built for compliance reduce red flags. Use these specs.
Double wall corrugated board at 32 ECT or higher to block odor.
Matte white or kraft finish. Avoid leaf graphics or neon colors.
Heat sealed mylar pouches inside the carton.
Fit the product snugly so nothing rattles.
Include a printed COA and invoice in a clear poly pocket on the inner flap.
Muse Custom Boxes ships these exact specs nationwide within five business days.
Labeling Mistakes That Trigger Xray
Inspectors share the top five label errors that send packages to the xray queue.
Writing “edibles” instead of “hemp food product.”
Using a fake return address or a residential address different from the permit holder.
Paying for postage with cash and no return address.
Listing contents value under five dollars for a two pound box.
Shipping to multiple unrelated names at the same PO box.
Fix these and you drop your odds of inspection by 70 percent.
What Happens After a Positive Xray
If the image looks suspicious, the inspector opens the parcel in a secure room. They photograph the contents and send the evidence to a local lab for field testing. If THC exceeds 0.3 percent, the package is tagged “seized.” You receive a letter within 30 days. You have 30 more days to appeal and provide third party lab proof. Without a response, the product is destroyed.
Real Numbers from Freedom of Information Requests
In 2023 USPS inspectors seized 7,400 hemp packages. Of those, 5,100 were released after owners produced valid COAs. The remaining 2,300 were destroyed. Average loss per box was 480 dollars. Most failures came from poor labeling, not illegal product.
