If you are a home care brand looking to get your laundry detergent, cleaning supplies, or paper products into Costco, you have probably read the standard Costco pallet display requirements. But household products are a different challenge from food or electronics. Liquid detergent bottles are heavy and prone to leaking. Bleach can damage the display itself. Paper products are bulky but crushable. And a single leaking bottle can ruin the entire pallet. The display must also pass ISTA 3E transit testing without allowing bottles to shift or leak. So if you are planning to sell household products at Costco, what do you need to know about the display, and how do you prevent leaks?
1. Leak Prevention Is the Number One Priority
This is the most important rule for household displays: prevent leaks. A 150-ounce laundry detergent bottle weighs over 10 pounds. If it tips over during transit, the cap can loosen and detergent will leak everywhere. A single leaking bottle can ruin the entire display and create a mess in the store. Every liquid bottle must be oriented with the cap facing up. The compartment depth should be at least half the bottle height to prevent tipping. Apply moisture-resistant coating to the tray. For high-risk products like bleach, consider polybagging each bottle individually.
2. Weight Separation: Heavy Liquids on the Bottom
A 150-ounce laundry detergent bottle weighs over 10 pounds. These must go on the bottom layer only. Dish soap and all-purpose cleaners (2 to 3 pounds) go in the middle. Paper towels and trash bags go on top. Never put liquid bottles above paper products — a leak will destroy the entire display. This weight separation is not optional. It is the difference between a display that arrives intact and one that arrives as a soggy mess.
3. Double-Wall Trays for Heavy Bottles
For bottom layers holding laundry detergent and bleach, use double-wall BC flute corrugated with 44 ECT minimum. The trays must be reinforced with corner supports for bottles over 5 pounds. For middle layers with dish soap and cleaners, C flute single-wall with 29 ECT is sufficient. For top layers with paper products, B flute single-wall is adequate. Using the right material grade for each layer saves cost without sacrificing safety.
4. Multi-Pack Bundles Need Custom Compartments
Costco sells many household products in multi-pack bundles — detergent in 2-packs, dish soap in 3-packs, paper towels in 12-packs. Each bundle needs a compartment sized to its specific dimensions. Do not try to fit a multi-pack into a compartment designed for a single unit. It will not fit securely and will shift during transit. Measure the actual bundle dimensions and design the compartment to match.
5. Paper Products: Keep Them on Top
Paper towels, toilet paper, and paper napkins are lightweight and crushable. They must be on the top 1 to 2 layers of the display. Never put liquid bottles or heavy items above them. Use B flute single-wall trays — paper products are lightweight so heavy material is not needed. The main concern is keeping them clean and dry.
6. Material Reference: What to Use for Each Product
| Product Type | Material Grade | Why |
|---|---|---|
| Laundry detergent, bleach | BC flute double-wall, 44 ECT + corner supports | Extremely heavy, leak risk |
| Dish soap, cleaners | C flute single-wall, 29 ECT | Medium weight, standard protection |
| Paper towels, trash bags | B flute single-wall | Lightweight, crushable |
7. Category Labels Help Shoppers Find What They Need
Household products are often purchased on autopilot — shoppers grab the same brand they always buy. Clear category labels (laundry, dish, cleaning, paper) help them find their section quickly. Use large, readable text and brand logos on the header sign and shelf edges. The faster a shopper can find their usual brand, the more likely they are to buy.
8. ISTA 3E Testing: What to Expect
Costco requires ISTA 3E testing for all pallet displays. For household displays, the most common failures are bottle cap loosening from vibration, liquid leakage, and tray collapse from heavy bottles. Test with actual filled bottles. Include a leak test — vibrate the display and check if any caps have loosened. A display that passes ISTA testing is far less likely to arrive with damaged products.
9. Layer Count Reference
| Product Type | Max Layers |
|---|---|
| Laundry detergent | 3–4 |
| Dish soap, cleaners | 4–5 |
| Paper products | 3–4 (due to bulk, not weight) |
Calculate total pallet weight to ensure it stays under Costco's 2,200-pound limit.
10. Timeline: Planning Your Household Display
The typical lead time for a Costco household display is 8 to 12 weeks. Household products are year-round, but spring cleaning season (March to May) sees increased display traffic. Plan your program at least 3 to 4 months in advance. For spring seasonal programs, start production by January.
FAQ
How do I prevent laundry detergent from leaking during shipping?
Every liquid bottle must be oriented with the cap facing up. The compartment depth should be at least half the bottle height. Apply moisture-resistant coating to the tray. For high-risk products like bleach, polybag each bottle individually.
What material grade is needed for heavy laundry detergent bottles?
A 150-ounce detergent bottle weighs over 10 pounds. Use double-wall BC flute with 44 ECT minimum and corner supports. For dish soap, C flute single-wall with 29 ECT is sufficient.
Can I put paper products on the bottom of a household display?
No. Paper products are lightweight and crushable. They must be on the top 1 to 2 layers only. Never put liquid bottles above paper products — a leak will destroy the entire display.
How should I design compartments for multi-pack bundles?
Each bundle needs a compartment sized to its specific dimensions. Do not try to fit a multi-pack into a single-unit compartment. Measure the actual bundle dimensions before designing.
What is the maximum layer count for household displays?
Laundry detergent — 3 to 4 layers. Dish soap — 4 to 5 layers. Paper products — 3 to 4 layers. Calculate total pallet weight to stay under 2,200 pounds.
Conclusion
Getting your household products into Costco with the right display comes down to three things: preventing leaks, separating heavy liquids from lightweight paper products, and using the right material grade for each layer. The brands that succeed are the ones that take leak prevention seriously and test thoroughly before shipping.
