Since early 2022, USPS has implemented “Nonstandard Fees” to address the rising costs of handling awkwardly sized or shaped parcels. But in July 2025, the impact is greater than ever—especially for China-based exporters shipping to the U.S. via USPS.
One of the most frustrating charges? The $4 “nonstandard length” fee, which can hit even the most innocently packed package if it’s just one inch too long.
This packing guide gives you all the insights you need to ship smarter in 2025 and avoid unnecessary USPS penalties.
What Exactly Is the USPS $4 Nonstandard Fee?
When Does USPS Charge the $4 Fee?
Starting in 2022 and reaffirmed in July 2025 updates, USPS applies a $4 surcharge to packages meeting any of the following:
- Length > 22 inches
- Length + Girth > 108 inches
- Irregular shapes, such as tubes or rolls without proper packaging
This applies to USPS Ground Advantage, Priority Mail, and First-Class Package International Service.

Why Does This Affect China-Based Exporters More?
Most eCommerce and accessory exporters in China ship flat-packed items in bulk—belts, caps, stationery, and tools. When packed in longer rectangular cartons, these often breach the 22” rule unknowingly.
For example, a 24" long, 3" wide box for belts automatically triggers the $4 fee—even if it weighs under 1 lb.
How to Measure and Pack to Avoid the $4 Surcharge?
What’s the Correct Way to Measure USPS Dimensions?
USPS calculates Length + Girth using this formula:
Length = Longest side
Girth = 2 × (Width + Height)
📦 Example Box:
- 22” L × 8” W × 6” H
- Girth = 2 × (8 + 6) = 28”
- Length + Girth = 50” ✅ (No surcharge)
📦 Bad Example:
- 24” L × 3” W × 3” H
- Girth = 2 × (3 + 3) = 12”
- Length + Girth = 36” ❌ (Triggers $4 fee for length > 22”)

What Are the Best Box Sizes to Avoid Fees?
Stick with under 22” in length, especially for belts, posters, scarves, and accessories. Try:
- 12” x 9” x 3” boxes for belts and gloves
- 18” x 12” x 6” boxes for small bundles
- USPS Flat Rate Envelopes where applicable

What Packaging Practices Can Lead to Hidden Fees?
Are Poly Mailers Safer Than Boxes?
Yes, flexible mailers under 22" long often avoid USPS surcharges. But beware of bulging items—mailers that expand too much in girth can still breach the 108” combined rule.
✅ Use poly mailers for:
- Socks, T-shirts, soft goods
- Jewelry in small pouches
- Accessories under 20” in length
Avoid for:
- Rigid objects (e.g., phone mounts, utensils)
- Tubular or oddly shaped items (trigger irregular shape fees)

What Common Mistakes Cause Unintended Fees?
- Using gift box-style packaging with excess void
- Adding thick bubble wrap that expands dimensions
- Mislabeling rolled goods as standard (should use square outer box)
Pro tip: USPS recommends testing boxes with a standard measuring slot tool used by fulfillment centers.

Should You Let Freight Partners Handle USPS Labeling?
Absolutely. By handing off label generation and customs declaration to your freight forwarder, you avoid errors that might flag packages for manual review and surcharges.
Best practice: Use DDU or DDP shipping models with USPS integration to fully control package formatting.
