What does flat rate shipping mean?

Flat rate shipping mean that the cost of that shipment will remain constant, regardless of what’s inside the package or the weight (as long as it fits the carrier's requirements). This approach simplifies the shipping process, as you don't need to calculate different rates for varying weights or distances.

For example, if you ship a 2-pound or 10-pound package, as long as it fits within the flat rate box provided by the carrier, the shipping cost will be the same. This is especially effective for businesses and online sellers, as it allows them to provide clear and predictable shipping rates to their customers and ultimately secure a better deal for them.

Flat Rates offer several advantages for the shipper, such as:

  • Easier budgeting: The cost will remain the same as long as it fits in the carrier-provided package (envelope, box, tube, and many more)
  • Cost efficiency: It can be cheaper for heavier shipments over long distances, as the flat rate often undercuts shipping costs.
  • Convenience: Flat rates are widely accessible, making shipping straightforward from our go-to carriers, such as FedEx, USPS, and UPS.
  • Customer satisfaction and transparency: Predictable and transparent shipping costs.
  • Competitive prices: Flat rates/ Carrier-provided package rates are cheaper than custom package rates.

Popular carriers like USPS, FedEx, and UPS offer flat rate shipping options which are now available in our Multi-Carrier Feature, making it a must-try option for your shipments.

How does flat rate shipping work?

When considering shipping options, it's important to understand how flat rates are tied to specific carrier-provided supplies, such as boxes, padded envelopes, express envelopes, mailers, paks, tubes, and many more. This connection simplifies the process and can lead to significant cost savings.

For instance, USPS offers flat rate boxes in different sizes, and as long as your items fit inside the package, you don’t need to worry about size or weight calculations affecting the cost.

Within these supplies, you can ship them for a fixed rate. As an example, if you need to send a package of books weighing 15 pounds across the country, you can use a USPS Medium Flat Rate Box. The cost will be the same as sending a 1-pound item in the same box, providing a predictable and cheaper shipping option.

Below, we will explore more in-depth the most popular shipping rates and, later on, the shipping supplies offered by USPS, UPS, and FedEx and provide tips on how to obtain them easily! It's important to note that flat rates can vary significantly depending on the carrier. Each major shipping company has its own set of guidelines and prices for flat rate shipping.

Where to get shipping supplies?

In the world of shipping logistics, the choice and use of carrier shipping supplies can significantly impact the efficiency of operations and the cost-effectiveness of shipments.

As we mentioned before, shipping supplies play a crucial role in flat rate pricing structures, simplifying shipping costs by charging a fixed rate regardless of weight (up to 70 pounds), size, and destination (although the last two factors can potentially impact the overall costs based on the chosen shipping carrier).

Now that we know the role of carrier shipping supplies and how they are linked to flat rate pricing structures, it's crucial to differentiate them from custom packages or unbranded shipping supplies.

Custom packages are generic packaging materials that businesses or individuals have at hand. These can include boxes, bags, or mailers. Unlike carrier shipping supplies, unbranded options may not always conform to specific carrier guidelines, which can potentially impact shipping costs.

In a previous blog post, we discussed the importance of properly placing shipping labels on packages. Buying shipping labels that correspond precisely to the flat rate box or envelopes you are using is essential when using carrier shipping supplies.

For example, attaching a Priority Mail Small Flat Rate Shipping Label to a Priority Mail Large Flat Rate Box will result in the package being returned. Properly using shipping supplies, including correct labeling, is crucial for smooth and efficient delivery; otherwise, extra charges may apply.

a. How to get USPS shipping supplies

Getting USPS shipping supplies is straightforward. You can visit your local post office to pick them up or order them online through their official website. Simply select the needed shipping supplies, add them to your cart, and check out. Supplies are delivered to your door without any shipping charges.

b. How to get UPS Shipping supplies

UPS also offers a variety of shipping supplies that can be ordered online for free through their UPS website if you have a UPS account (create an account if you don't have one already). Available supplies include Express Envelopes, various sizes of boxes, and tubes. You can also visit a nearby UPS store to pick up supplies directly, making it easy to get what you need quickly.

It’s worth noting that the quantity of shipping supplies per order is limited. However, you can periodically reorder supplies based on your recent shipping volume. If you need additional supplies to accommodate a higher volume, you must contact UPS Customer Service to place an order.

c. How to get FedEx Shipping supplies

FedEx offers a variety of shipping supplies. You can buy packing supplies (tape or cushioning) and boxes individually, paying a fixed price at a FedEx office, or take advantage of the free FedEx Express packaging available online.

To order supplies online, go to the FedEx website and explore the “Shipping” section. You must have a FedEx account to order shipping supplies.

Carrier-provided packages: Airpals key to shipping flat rates

At Airpals, our multi-carrier shipping platform offers a unique "Carrier Provided Packages" feature, which integrates with carriers' flat rate pricing and shipping supplies. This feature is designed to simplify the shipping process for our users by leveraging standardized packaging options that come with fixed rates and are provided directly by carriers such as USPS, UPS, and FedEx.

As you can tell, "Carrier Provided Packages" are related to flat rate pricing and shipping supplies, which have many benefits. First, users can benefit from fixed shipping costs regardless of the package's weight or destination, making it easier to budget and manage shipping costs. Second, using "Carrier Provided Packages" allows shippers to choose from standardized shipping supplies specified by the carrier, reducing shipping errors and delays.

Now Airpals users have two options: "Custom Packages," where they input specific dimensions and weight for their packaging, and "Carrier Provided Packages," where they can choose from different types of standard boxes and envelopes offered by carriers under this feature.

To start using this feature on our platform, select the "Carrier Provided Packages" option during the "Package Info" step of placing an order, enter the package weight, and review the available flat rate options each carrier provides.

How to get cheaper shipping rates by using carrier-provided packages

You can save on shipping costs by choosing flat rate options from carriers like USPS, UPS, and FedEx. These packages come in standard sizes, which helps to minimize shipping expenses and eliminates the need for custom packaging.

Now, we'll show you one real-life example of how carrier-provided packages have an impact on shipping expenses.

a. Case study

Emily runs a home decor business and frequently ships heavy items, such as ceramic vases, to her nationwide customers. She recently discovered the "Carrier Provided Packages" option on our multi-carrier shipping platform and decided to give it a try.

Custom Package: Emily’s custom box dimensions are 11x8x6 inches, and the package with the ceramic vase inside weighs 25 pounds. When she enters these details, the shipping cost is calculated based on the weight and dimensions. Emily usually buys these custom boxes in packs of 10, which costs her a total of $30.

Carrier Provided Package: Emily chose a carrier-provided box that is 11 1/4" x 8 3/4" x 6" inches and fits his product perfectly. The weight of the package with the vase inside is still 25 pounds. However, the carrier-provided box falls under a flat rate category.

Custom Package Shipping Cost:

  • $28.62 (UPS Ground Saver)
  • $35.73 (FedEx Ground)
  • $48.34 (USPS Ground Advantage)

Carrier Provided Package Shipping Cost:

  • $14.38 (USPS Priority Mail - Medium Flat Rate Box)

* Please note that carriers' rates can change over time. The rates in this case study are from June 2024.

Emily is smart and chose to level up her shipping game by using Airpals to purchase and print her shipping label. By selecting the "Carrier Provided Package" feature, she bought her shipping label for just $14.38, which saved her $14.24 on the label and an additional $3 on the carrier-provided box.

By consistently using "Carrier Provided Packages" for her shipments, Emily has accumulated significant savings over time. This has allowed her to reinvest in her business and offer more competitive pricing to her customers.

In summary, Emily saved a significant amount on shipping costs by using our platform's "Carrier Provided Packages" feature. This demonstrates the cost-effectiveness of using carrier-provided packaging and flat rates. By doing so, Emily not only saved money but also streamlined her shipping process through standardized packaging options.

We believe leveraging our "Carrier Provided Packages" feature will elevate your shipping operations, ensuring seamless, cost-effective operations for your business or personal shipping needs.
