Cheapest Way to Ship Pet Food
Pet food is heavy and bulky, making USPS Flat Rate boxes the go-to for cost savings.
Shipping Options for Pet Food
Pet food is one of the heaviest common e-commerce categories, which makes shipping costs a significant factor. A small bag of premium dog food weighs 4-8 lbs, and canned food is even heavier. Weight-based shipping gets expensive fast, so USPS Priority Mail Flat Rate boxes are the most popular option for pet food sellers. The key is fitting as much product as possible into the flat rate box to maximize savings. For very heavy shipments (20+ lbs), FedEx and UPS Ground become more competitive.
| Service | Carrier | Est. Cost | Speed | Best For |
|---|---|---|---|---|
| Priority Mail Flat Rate (Medium)Recommended | USPS | $16.10 | 1-3 days | Small bags or canned food bundles up to 20 lbs at a fixed cost |
| Priority Mail Flat Rate (Large) | USPS | $22.45 | 1-3 days | Larger bags of kibble or multi-can orders up to 70 lbs |
| FedEx Ground | FedEx | $12-20 | 3-7 days | Heavy bags over 15 lbs where flat rate no longer saves money |
| UPS Ground | UPS | $12-20 | 3-7 days | Bulk or subscription orders shipped to residential addresses |
Packaging Tips for Pet Food
Pro Tips
- Always compare flat rate versus weight-based pricing for your specific order. For items under 3 lbs shipping short distances, Ground Advantage at $6-8 beats flat rate pricing.
- For subscription pet food businesses, negotiate commercial rates with USPS or UPS — volume discounts of 15-25% are common for consistent shippers.
- Double-bag dry food in case the original packaging tears during transit. A ripped bag means loose kibble in the box and a dissatisfied customer.
Important Considerations
Weight is the primary cost driver for pet food shipping. Always weigh the packaged product before purchasing a label to avoid costly weight surcharges at the post office. USPS Flat Rate boxes have no weight limit (technically 70 lbs), making them extremely valuable for heavy pet food shipments.
Frequently Asked Questions
USPS Priority Mail Flat Rate boxes are almost always the cheapest option for heavy items. The Medium Flat Rate Box ships up to 70 lbs for a fixed $16.10, and the Large Flat Rate ships for $22.45 regardless of weight. For a 10-lb bag of dog food, flat rate saves $5-15 compared to weight-based shipping across the country.
Yes, canned pet food ships without any restrictions through USPS, FedEx, and UPS. The main challenge is weight — a case of 12 cans easily weighs 10-15 lbs. Pack cans tightly in a Flat Rate box with minimal empty space to prevent shifting, and reinforce the box bottom with extra tape to handle the concentrated weight.
If you're running a pet food subscription business, flat rate shipping simplifies pricing — you charge a fixed shipping cost that matches the flat rate price. For orders exceeding Flat Rate box dimensions, negotiate commercial rates with FedEx or UPS, which offer 20-30% discounts for consistent weekly volume. Building shipping costs into the product price also simplifies the checkout experience for subscribers.
