Granite vs Quartz Countertops: The Import Decision

Two Materials, One Countertop Market

Walk any kitchen showroom and the two countertop kings are granite and quartz. Granite is a natural igneous rock, cut from quarries in China, India and Brazil, and sold slab by unique slab. Quartz is engineered: about 90% ground quartz bound with resin and pigment, made in factories with a perfectly repeatable look. They cost about the same at the slab level (roughly USD 10 per square foot at big-box retail, with installed prices typically USD 40-100 per square foot), and both test well for durability. But they behave differently in a kitchen, they move differently through supply chains, and — since December 2023 — they are regulated differently in at least one major market, because Australia banned the manufacture and import of engineered stone entirely. If you are an importer deciding what to stock, this is the comparison that matters.

Heat: Granite Wins, Clearly

Granite forms in the earth at searing temperatures and shrugs off a hot pan straight off the stove — thermal shock is not a realistic worry on a granite counter. Quartz is the opposite: its resin binder softens and cracks under direct heat, so a hot pan can leave a permanent mark or a crack. The standard advice on quartz is 'trivet always'; on granite it is 'don't be reckless, but it will take it'. For kitchens that actually cook — restaurants, rentals, big families — this is a real advantage, not a marketing line.

Stains: Quartz Wins, Because It Is Non-Porous

The stain test is where quartz shows its engineered nature. Consumer Reports' countertop testing scores quartz higher on staining (about 2.3 points out of 100 over granite in its head-to-head), because quartz is non-porous — wine, beet juice, oil and food coloring sit on the surface. Granite is natural and slightly porous: it needs a sealer, applied at installation and renewed periodically, or dark liquids can soak in. The practical difference: a quartz counter is maintenance-free on stains, a granite counter needs sealing discipline. That one line of maintenance is why many landlords and busy families choose quartz — and why granite's supporters say sealing twice a year is a five-minute job.

Looks, Weight and Seams

Granite's case is uniqueness: every slab has its own veining, mineral specks and movement, and buyers who want a one-of-a-kind natural surface will pay for it. Quartz's case is consistency: because it is manufactured, color and pattern are uniform across slabs, seams are predictable, and it can mimic marble veining or almost any color. There are two practical differences for installers. Quartz is lighter and cuts more predictably — easier to handle, easier to trim. Granite is heavy, needs structural support and careful handling, and its natural variation means seams must be matched slab to slab. Both are durable; neither is indestructible — both can chip on a hard edge hit. Decide on looks and maintenance, not toughness.

The 2023 Engineered-Stone Ban: A Real Shift

In December 2023 Australia banned the manufacture, import and supply of engineered stone, following years of rising silicosis cases among workers cutting it. The ban covers the quartz products described in this article, with narrow exemptions for some low-silica products. This matters to importers in two ways. First, if you sell into Australia, quartz countertops are effectively off the table — natural granite, marble, porcelain and other materials take their place, and demand for natural stone slabs in the Australian market has strengthened as a result. Second, the silicosis risk is not an Australian-only concern: regulators in other markets are watching, and dust controls on quartz fabrication are under scrutiny globally. It is one more reason a natural-stone position is a defensible one, and it is worth asking any quartz supplier about the silica content and the destination market's rules before you commit a container.

What to Decide, and What to Order

Stock both if your market is broad — they sell to different buyers — but know which customer each serves. Granite for the kitchen that cooks, the buyer who wants natural uniqueness, and any market tightening on engineered stone; quartz for the renter-grade and family market that values zero maintenance and predictable seams. When you order granite, specify the grade (commercial vs premium), thickness (2 cm vs 3 cm), edge profile, and insist on slab photos or video before cutting — granite varies slab to slab. When you order quartz, confirm the silica content, the resin system's heat warranty, and the destination market's regulatory position. Either way, source from a factory that shows you the actual production — the container should arrive as quoted, not as imagined.
