6 Steps to Vet a HanStone Quartz Supplier Without Wasting Your Budget

Who This Checklist Is For

You're a contractor or designer. You've got a project — maybe a kitchen reno, maybe a whole development. You've seen HanStone's website, you like the look of Montauk and Tofino, and now you need to actually buy the slabs.

This is the checklist I use when vetting a new supplier for our projects. It's built from 6 years of procurement spreadsheets and a few expensive mistakes. If you follow these 6 steps, you'll avoid the classic traps that eat into your margin.

Step 1: Check Their Inventory — Not Just Their Brochure

The first thing I do is ask for a live inventory list. Not the catalog. Not the PDF. I want to know what's actually in their warehouse.

When I was starting out, I wasted a month on a supplier who had beautiful photos of the HanStone Calacatta series. Turns out they only stocked 3 of the 12 colors. Every special order took 5 weeks (which, honestly, killed the project timeline).

Specific ask: “Can you send me your current inventory for HanStone slabs over 110” by 55”? I want to see which colors you have in stock today, not what you can order.”

If they hesitate or deflect, that's a red flag.

Step 2: Get a Quote That Includes Everything (Then Add 10%)

I've seen quotes that look great. Quote says $2,800 for the material. I'm thinking, that's solid. Then the final invoice was $3,450 because of delivery, drop-off fees, and a “handling surcharge” nobody mentioned.

So, here's my template:

“Please quote me for [specific HanStone color, e.g., Tofino] in [size, e.g., 112”x56”]. Include all costs: material, delivery to [your location], unloading, any handling fees, and a breakdown of payment terms. This is for budget approval, so I need the total number I can expect to pay.”

Then I add 10% to *that* number for my budget. Because there's always something. (Surprise, surprise.)

Step 3: Test Their Lead Time — With a Real Deadline

Suppliers will tell you their standard lead time. Great. But I want to know two things:

1. What's the lead time for an order right now, this month?
2. What happens if you need it faster? Do they offer rush? And what does rush actually cost? (Or rather, what does it cost including everything?)

I once had a supplier quote a 2-week lead time, but they didn't mention their “fabrication queue” adds 5 days. So the effective lead time was 19 days, not 14. By the time I found out, the client was already calling me.

Step 4: Ask About Minimums — Before They Ask About Your Budget

This is the step that matters most to smaller contractors. I've had suppliers look at my order size and literally ask, “Oh, is this a residential job?” in a tone that implied they'd rather not bother.

Don't accept that. Small doesn't mean unimportant—it means potential.

Ask directly: “Do you have a minimum order value or quantity? If I'm ordering two slabs of HanStone's Tranquility for a single kitchen, is that something you handle, or do you prefer larger orders?”

When I was starting out, the vendors who treated my $200 orders seriously are the ones I still use for $20,000 orders. A good supplier doesn't need a minimum to give you good service, they just need a clear spec.

Step 5: Check Their Edge Finishing — Get Samples, Not Photos

This one's a bit of a pro trick. The edge profile of a quartz slab is a deal-breaker for a lot of customers. A polished bevel looks different in a showroom photo than it does in a kitchen with morning light hitting it from the side.

Ask for a physical sample of the edge finish you plan to use with that specific HanStone color. Ideally a corner sample. Put it on your desk. Look at it for a week. Does it still look good? Does it catch light in a way that shows the pattern well?

I didn't fully understand this until a client rejected a completed countertop because the edge didn't match what they'd seen in the brochure. That was a $1,200 redo when the supplier (correctly) pointed out the sample I'd approved was different from the final product's edge. Now I get physical samples first. Every time.

Step 6: Read Their Terms for Replacements and Damage

Last step, and possibly the most overlooked. What happens if a slab is damaged during fabrication or delivery? Who's responsible?

Standard terms often say “responsibility transfers upon unloading.” But unloading is where damage often happens. So I ask: “Can you add a clause for replacement of a slab if it's damaged within 48 hours of delivery, before I've cut it? I'll pay for the replacement material, but I want to avoid paying a second delivery fee if the damage is cosmetic or superficial.”

Not all suppliers will agree, but the ones who are confident in their materials usually do. And the ones who are inflexible? That's useful information for future decisions.

One Thing to Watch Out For

The biggest mistake I see contractors make is falling in love with a color before checking inventory and lead time. You see a stunning HanStone Ridge in a showroom, you picture it in the project, and suddenly you're rationalizing every other red flag because the stone is just... right. That's the trap.

Follow the checklist. It's not glamorous. But it saves you money and stress. At least, that's been my experience with 40+ projects over the last few years.
