Shipping Policy

We make every effort to find the most economical means of shipping products to you, and we can ship to virtually any address in the United States. Note that some products (like rocket motors and some batteries) must be shipped by ground transportation only, so please allow sufficient time for your products to arrive.

When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page. Shipping estimates are just that--estimates--and we make every effort to ship your package as soon as possible, so it enters the mailstream as soon as practical.  Once we deliver the package to the carrier, the delivery schedule is out of our control.

Please also note that the shipping rates for many items we sell are size and weight-based. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound. You can find the shipping costs by adding your destination city, state, and postal code in the shopping cart page.

You Pay Only the Cost of Shipping

At Rocketry Works, we don't make a living off of your shipping charges. We charge only what it costs us to ship your order to you. That's just the kind of straight forward company we are.  So if your shipping cost seems high, don't worry. You'll see a refund if it costs less to ship your order than the website estimated.  Websites, after all, are just software, and shipping is an area where a human can often outsmart the software when the order items are at the shipping station. You'll see this most often when orders contain heavy or bulky items in addition to special items like motors or igniters.  Shipping estimation software can handle most use cases, but when orders get weird, you can count on humans better. If you have an questions during your order, feel free to give us a call, and we can give you a better estimate.

Damage in Transit

From time to time, a package may be damaged in transit.  If the damage extends to the contents of a package, or if the damage causes loss of contents, please contact Rocketry Works (, and we'll work with you to replace the damaged item(s).  We will need  your help documenting the damage, so please include your order number, a description of the damage, and photos of the damaged package and damaged items.  This will help us file a claim with the carrier. We will get you a replacement on its way to you as soon as possible, without waiting for the claim from the carrier.

USPS for Lightweight Packages

You may choose the carrier and ship method during the checkout process to suit your budget and your schedule. Most small or lightweight products will likely ship cheaper via US Postal Service. Lightweight items--usually less than a pound, or items that can fit in a priority mail flat rate box--will ship cheapest via Priority Mail, which usually takes between 1 and 3 days. Priority Mail package to most metropolitan areas will likely take 2 days, while more rural areas usually take 3 days. The USPS does not guarantee delivery times, so USPS packages may take longer than these estimates.

FedEx for Heavy or Bulky Packages

Heavier or bulkier items will likely ship cheapest via FedEx, and delivery times are directly proportional to distance from Tucson, according to this FedEx delivery time map:



USPS Shippable Motors with 30 grams of Propellant or Less

Small motors with no more than 30 grams of propellant per grain, like Estes D motors and smaller, and many Aerotech single use motors into the F range, qualify for USPS Ground shipping. Rocket motors and igniters that qualify to ship via USPS Ground (formerly Parcel Post), may take 2 - 7 days to arrive, depending on the distance from Tucson, Arizona. USPS Ground packages can be delayed unexpectedly at a greater frequency and severity than Priority Mail or First Class packages, sometimes taking 2 weeks to arrive. USPS Ground shipments to Alaska, Hawaii, and US territories like Puerto Rico, USVI, and Guam can take longer, as ground shipments go by boat. Plan accordingly, particularly around launches or holidays. Note that many motor manufacturers have found clever ways for their larger motors to qualify for USPS shipping. Small single use motors, or reloadable motors with properly sized individual grains that are packaged separately can fall below the 30 gram limit, so you will see some reloadable motors up to J power that can ship USPS Ground. Every motor on the Rocketry Works website indicates whether it is USPS Shippable or HAZMAT only.

HAZMAT Shipping for Larger Motors

Motors with more than 30 grams of propellant per grain must ship via a commercial carrier's Hazardous Materials service, which incurs a $37 HAZMAT fee per shipment in addition to shipping charges. So as many motors as you can fit into a single shipment will be covered by the same HAZMAT fee.  In addition to the hazmat fee and shipping charges, the double-packaging requirements mean that the box the motors ship in will be bigger than you might expect. We do our best to keep your shipping costs as low as possible. Some single use F motors, and all single use motors G power and up, as well as most reloadable motors from H power and up must ship HAZMAT. Every motor on the Rocketry Works website indicates whether it is USPS Shippable or HAZMAT only. HAZMAT packages will require a direct signature.

Free Shipping Offers

By default, any free shipping offers are for the least expensive ship method. If you need your order delivered by a faster method, free shipping will not apply. Some items--notably large items like launch pads--may not qualify for free shipping.

International Shipping

International shipping outside the United States is not supported at this time. Model rocket motors and igniters can not be shipped internationally.

Local Pickup or Launch Pickup

Rocketry Works is happy to waive shipping fees for orders picked up locally, either at Rocketry Works' facility, or at a launch listed in Rocketry Works' calendar. This is particularly cost effective for orders including HAZMAT motors. To waive shipping charges for local pickup orders, just use the coupon code PICKUP in the cart or checkout, and indicate in the order comments where you plan to pickup up your order.  Orders placed before 6 pm the night before an in town launch will be ready the at the next day's launch.  Out of town launches may have earlier deadlines.
