The price of the stone is the smallest question
Ask three suppliers for a square foot price and you will get three numbers that cannot be compared, because each one stops at a different point in the chain. One includes freight, one stops at the warehouse door, and one quietly assumes you will handle the drayage yourself. On an island served by a single regulated shipping lane and taxed on total landed value, the material price is the least decisive line on the sheet. The buyers who come out ahead in Puerto Rico are not the ones who negotiated hardest on stone; they are the ones who understood which lines they could actually influence and which were fixed before the conversation started.
The lines that make a delivered number
Every honest quotation for this island resolves into the same components, whatever order a supplier chooses to present them in, and a buyer who forces all three bids into this shape can finally compare them:
- Material, priced by unit and square footage against a firm specification.
- Ocean freight and insurance on the Jones Act lane from Florida to San Juan.
- Island sales-and-use tax, computed on the combined landed figure.
- Drayage from Puerto Nuevo plus terminal charges and any waiting time.
- Waste allowance and cuts, which decide the quantity you pay for on every other line.
Freight: the line you cannot engineer away
Mainland to island carriage requires US-flag, US-built and US-crewed vessels, which raises the freight cost per container relative to a comparable foreign-flag route. No supplier can negotiate that structure away, and any quotation that appears to have done so has usually moved the cost somewhere less visible. What you can influence is how efficiently the container is filled. A dense, well-planned load carrying the exact quantity for the whole project spreads a largely fixed cost across more finished area than three partial shipments ever will, which is why quantity accuracy is worth more here than a discount on the stone.
Island tax sits on top of freight, not beside it
Puerto Rico charges no federal customs duty on mainland material, because the shipment is domestic. What applies instead is the island sales-and-use tax at 11.5 percent, made up of a 10.5 percent state portion and a 1 percent municipal portion, administered by Hacienda through the SURI portal. Crucially it is computed on total landed cost, freight and insurance included. That means the freight line quietly enlarges the tax line, which is exactly why a material-only comparison between two suppliers is misleading. Confirm current rates with your tax advisor before fixing a contract price.
Drayage, access and the second handling
Once the container is released, the last few miles generate their own costs, and they are the ones most often left out of an early budget:
- Drayage from the terminal to the site, priced by distance and truck type.
- Free time and demurrage, which accrue quickly on a heavy container.
- Transfer to a smaller truck where a gated urbanizacion caps vehicle length.
- Manual offloading where no forklift can reach the setting area.
- The barge leg via Ceiba for anything bound for Vieques or Culebra.

Waste, cuts and the quantity you actually order
Waste is the line buyers cut first and regret fastest, because on this island a shortfall is not a trip to the yard. It is another sailing, another drayage charge and another tax computation on a small consignment. Order the allowance with the main consignment and it costs a fraction of what it costs later. Sensible allowances depend on the work in front of you:
- Simple rectangular terrazas with a running layout waste least.
- Diagonal patterns and curved edges generate substantially more offcut.
- Pool surrounds with radius coping need extra for shaping and breakage.
- Any pattern with a border or a feature band needs its own separate count.
What the stone choice does to installation
The material decision reaches past the invoice and into the labor line, and on a bonded island installation is where a poor choice becomes expensive:
- Consistent thickness lets a crew work quickly without shimming every unit.
- Calibrated edges hold a joint line and cut rework at the perimeter.
- Fewer sizes on site means less sorting and fewer wrong cuts.
- Dense, low-absorption stone is more forgiving of a wet setting week.
None of these show up on a material invoice, but every one of them shows up on a labor bill, and on a bonded island the labor bill is frequently the larger of the two. A cheaper stone that arrives out of tolerance quietly transfers cost from the supplier to your installer.
Getting a number you can hold
Send areas by use, thickness by duty cycle, the pattern you intend, an honest description of site access and the week you want to start setting. That produces a delivered figure rather than a square foot teaser, and it lets you compare two suppliers on the same basis for the first time. It also lets a supplier tell you honestly where a cheaper choice would cost you more in labor. Support across the island is set out on the island-wide stone supply support page. One accurate container beats three cheap ones every time on this island.
