Hanstone Quartz Supply: A 7-Point Inspection Checklist Before You Accept a Delivery

This checklist is for anyone buying or accepting Hanstone quartz supply. Whether you're a fabricator, a kitchen contractor, or a designer signing for a delivery, run through it before you put a slab on the truck. It takes about 20 minutes. It's the closest thing to free insurance I know.

I'm a quality compliance manager at a countertop distributor. I review about 1,800 slabs a year before they leave our yard. Since 2022, I've rejected roughly 4% of first deliveries. The reasons weren't always dramatic. Often it was a mismatch between the invoice and the slab label, or a chip hiding under a cardboard edge protector.

When I first started inspecting slabs, I assumed that if a slab arrived intact, everything else was fine. Four years later, I know better. 'Intact' is the lowest possible bar. The expensive defects are the ones you can't see until the slab is on the saw.

I still remember signing off on a multi-slab order of Hanstone Quartz Eden and second-guessing myself for the next two weeks. The labels matched. The lot numbers matched. I still worried. I didn't relax until the install photos came back. That feeling is why I made this checklist.

The 7-point Hanstone quartz receiving checklist

1. Check the slab label against the invoice

Before anything moves off the truck, find the packing slip and match it to the slab labels. The series name, finish, thickness, and dimensions all have to line up. If you ordered Hanstone Quartz Eden, the label should say exactly that. If the invoice says Eden but the label says something else, don't accept it. I've caught two wrong-series deliveries in 2025 alone.

2. Check lot numbers before you unload

If your order has more than one slab, check the lot or batch numbers before unloading. They should be the same for slabs going into the same job. Quartz can shift slightly between production runs. Two Eden slabs from different lots can look fine in the yard and noticeably different in a kitchen. Lay the slabs side by side, peel back a small corner of the protective film, and compare under daylight. If you see a mismatch, call your Hanstone quartz supply rep before you cut anything.

3. Inspect edges and corners with light

Run your hand along every edge. Then do it again with a bright light. Cardboard corner protectors hide a lot. I've had slabs arrive with the corner protector glued over a chip that was clearly not from transit. In Q1 2024, a batch came through with an edge profile that was off by 1/16 inch across the board. The vendor redid it at their cost, but we lost three days.

Pay attention to the unloading crew too. If they're wearing shower shoes, ask them to stop. Shower shoes have no grip, and a slab edge can do real damage to a foot or a countertop edge. It sounds like a strange thing to put on a checklist, but I've seen it.

4. Check the polished surface

Clean the surface with a dry microfiber cloth. Then shine a flashlight across it at a low angle. You're looking for pinholes, pits, or areas that don't have the same gloss as the rest of the slab. Actually, you don't need a lab to check surface quality. I carry a straightedge and a few clean glass bottles. Set a bottle upright on the slab and slide it slowly. A smooth, well-polished surface won't catch or chatter. If the bottle tips or stops, there's a bump you need to look at.

5. Measure thickness at multiple points

Measure the thickness at every corner and at the midpoint of the long edges. Use a caliper if you have one. If you're getting 3 cm slabs, they should measure close to 3.0 cm, not 2.7 under the factory label. Small differences can make seams and undermount sinks a nightmare.

6. Confirm documentation and warranty details

Before the truck leaves, get the paperwork. That means invoice, batch numbers, warranty registration, and care instructions. If a claim sounds too good, ask for it in writing. Per FTC guidelines (ftc.gov), product claims need to be truthful and substantiated. If someone tells you the quartz is 'maintenance-free forever,' that's not something I'd rely on without a document. And if you're dealing with a reseller, ask whether they're an authorized Hanstone-quartz dealer.

7. Plan storage and site prep before installation

Slabs belong on an A-frame or a sturdy wall rack, leaning upright. Do not store them flat. If you don't have a storage area ready, don't accept the delivery. Also think about the room. If there are baseboard heaters, clean them before the countertop work begins. The question 'how to clean baseboard heaters' sounds unrelated, but it isn't. Dust from a dirty heater falls into cabinet bases and can contaminate adhesives and seam bonders. A five-minute vacuum job prevents a call-back.

Common mistakes I still see

• Skipping the flashlight test because the slab 'looks fine.' That's how pinholes end up installed.
• Accepting a damaged box or edge protector. If the cardboard is cracked, the edge underneath is worth checking before you sign.
• Mixing lot numbers because 'it's for different rooms.' The eye can tell, and your customer will tell you.
• Trusting verbal promises about stain or scratch resistance. Get it on the warranty document.

Five minutes of verification beats five days of correction. That's not a slogan. It's a cost calculation.

The best inspection is the one you do before the slab enters your shop or your job site. Once the saw touches that edge, you own it. Honestly, this checklist won't catch every problem, but it will catch the ones that are catchable. That's the point.
