Have you noticed that your mailing and shipping costs change even when you’re sending the same package to the same place? One key reason for these fluctuations is something called demand surcharges.
Demand surcharges are extra fees that shipping carriers add during busy times when demand for shipping is high. These surcharges help carriers manage increased volume, labor shortages, and other challenges that come with handling more packages than usual. This is a standard practice that helps carriers deliver your packages on time, even during the busiest seasons.
Carriers impose demand surcharges for several reasons. During peak seasons like Christmas or Black Friday, the volume of packages increases significantly. To manage this volume, carriers often add surcharges to help cover the extra costs associated with handling more shipments.
Another factor is fuel prices. When fuel costs rise, carriers face higher operating costs, which typically results in fuel surcharges on rates.
Packages that require extra resources for delivery due to their weight, unusual shape, or special packaging will receive an Additional Handling surcharge. Specifically, packages with oversized dimensions will incur a Large Package Surcharge to offset the additional resources needed for their delivery. You also have to be careful that your packages do not exceed a carrier’s maximum weight or size limits or they will receive an Over Maximum Limit surcharge to cover the extra costs and resources required for delivery.
Additionally, busy shipping areas can lead to delays, prompting carriers to apply congestion surcharges. Finally, deliveries to remote locations can incur additional costs, leading to remote area surcharges.
By staying informed about these factors, you can better anticipate mailing and shipping costs during busy periods.
Demand surcharges are temporary fees that arise during peak demand periods, such as the holidays, and usually last only until the demand decreases. As we enter the holiday season, it’s essential to monitor postage costs and any potential surcharges from carriers during these busy times. Staying informed about how these temporary surcharges can impact your postage rates is important, and that’s where we can help you.
Additionally, carriers often impose shipping deadlines to ensure timely delivery by the holidays. To ensure your shipments arrive on time and at the best possible price, it’s essential to stay informed about the latest pricing trends and shipping deadlines.

Delivery is made by the country's postal service in 3 - 5 business days, depending on the destination.
Generally, it takes Priority Mail International six to ten business days. USPS hands off shipments at the border of the destination country before the local postal service completes the delivery.
While price varies depending on weight and destination, rates for this service begin at $17 dollars.
USPS Priority Mail generally delivers in 2-3 business days. First-Class Mail, while more economical, typically takes 1-5 business days for delivery.
NetStamps are USPS-approved blank labels on which you can print your own stamps. Simply buy postage on Stamps.com, use any printer to print on a NetStamps sheet or roll, and stick the NetStamp to an envelope, postcard, or other First Class Mail.
Nonmachinable envelopes might be non-rectangular, rigid, unevenly thick, or have non-paper closures, meaning they cannot be processed efficiently by USPS's automated sorting equipment, and require special handling, resulting in a surcharge in addition to the standard postage.

Flat Rate Envelopes are ideal for documents or small, dense items weighing 4 lbs or less, as they offer a single price based on the destination country. For items between 4 lbs and 70 lbs, or those that don't fit into the Flat Rate Envelopes, you'll need to ship by weight using your own packaging. It’s more affordable to use Flat Rate boxes if your item is under 20 lbs.
