People arriving in Sint Maarten from almost anywhere else in the Caribbean bring an assumption with them: that importing a car, a container of household goods or trading stock will attract a substantial duty calculated on its value. In most of the region that assumption is correct, and it is frequently the largest single cost of relocating or of stocking a business.

Sint Maarten is genuinely different, and the difference is not marketing. The Government of Sint Maarten's own description of its Customs department states that Customs Sint Maarten "differs from most other countries in the region in that it is mainly a law enforcement agency and not primarily an import duty collecting organization", and that "the only tax levied by Customs Sint Maarten is tax/excise on unleaded gasoline."

That single fact explains a great deal about how this island trades. It also gets over-read, because "no general import duty" is not the same as "free", and the costs that remain are the ones that surprise people.

What Free Port Status Removes

The absence of a general ad valorem import duty removes the cost that dominates importing elsewhere in the region. There is no percentage of CIF value taken at the border on ordinary goods, which means:

  • Retail and wholesale businesses can stock inventory without a duty layer built into landed cost, which is the underlying reason the island's retail sector competes on price with the rest of the region.
  • Households relocating can bring furniture, appliances and personal effects without facing a valuation exercise on everything in the container.
  • Businesses importing equipment, from kitchen fit-outs to machinery, avoid a cost that would otherwise sit on the capital expenditure.

This is the substance behind the island's duty free reputation, and it is real. It is also frequently confused with a different claim, which is that Sint Maarten is tax free generally. It is not, and our page on whether Sint Maarten is tax free deals with that confusion directly.

What Still Applies

Five things survive the absence of general duty, and together they account for most of what importing actually costs.

1. Excise on fuel

Excise on unleaded gasoline is the one tax Customs collects. It is not a consumer-facing import question for most people, but it is worth knowing that it exists, because it means the border is not a zero collection point as a matter of principle.

2. Turnover tax on the onward sale

This is the one businesses most often miscalculate. Sint Maarten's turnover tax at 5% attaches to the delivery of goods and the supply of services inside the territory. Goods that entered without duty are still sold here, and that sale is within the charge.

Because there is no input credit mechanism, the tax compounds along the chain. An importer selling to a distributor selling to a retailer produces 5% at each stage, each time on a base that already contains the previous stage's tax. Landed cost being low does not mean the tax burden across the chain is low, and businesses that price by marking up landed cost without accounting for this consistently understate their own costs. Our guide to turnover tax works through the compounding.

3. Clearance, handling and the broker

Goods still have to clear. That means documentation, port and terminal handling charges, storage if the container is not collected promptly, and in practice a customs broker, because the paperwork is not the place to learn by doing. These are real costs and they are the ones that fill the gap where duty would otherwise sit. Demurrage on a container left sitting is the avoidable one, and it is avoidable only by having the paperwork ready before the vessel arrives.

4. Vehicle specific requirements

A car is not just cargo. Importing one brings requirements that have nothing to do with tax: the original title and bill of sale, evidence of ownership, inspection against local roadworthiness and safety standards, and then registration, plates and insurance before it can lawfully be driven. Left-hand drive is the norm here, which matters if the vehicle is coming from a right-hand drive market.

The practical advice from anyone who has done it is the same. Establish that the specific vehicle can be registered here before shipping it, not after it lands. A car that cannot pass inspection is an expensive object sitting in a port.

5. Restrictions and controls

Customs being a law enforcement agency rather than a revenue agency does not make it a soft border. It makes it a border focused on what is moving rather than on what it is worth. Prohibited and restricted goods, controlled substances, firearms, certain agricultural and food products, protected species and anything requiring a permit are all controlled, and the enforcement posture on those is the department's primary function rather than a sideline.

The French side is a different customs territory

Saint-Martin, the French side, sits within a different fiscal and customs framework, and goods moving between the two parts of the island are not automatically moving within one territory for these purposes. Businesses that supply across the border, and residents who buy on one side and bring goods to the other, should establish the position for their specific goods rather than assuming an open island. Our guide to the French and Dutch sides covers the wider differences.

Practical Sequence for a Business Import

  1. Confirm the goods are not restricted and that any permit required is in hand before shipping. This is the failure that costs weeks rather than dollars.
  2. Appoint a broker early and give them the commercial invoice, bill of lading and packing list before the vessel arrives.
  3. Price the onward sale properly, with turnover tax inside the price rather than discovered after it, and with the compounding accounted for if you sit mid-chain.
  4. Budget the real line items: freight, insurance, port and terminal handling, broker fees, inland transport, and storage if anything slips.
  5. Collect promptly. Demurrage is the most common avoidable cost in the whole exercise.

And for a Household Relocation

The same border logic applies, with the emphasis shifted. The container itself is unlikely to attract duty, so the costs are shipping, insurance, handling, clearance and delivery. The two things worth doing carefully are an itemised inventory, because clearance goes faster with one and slower without, and a realistic assessment of whether shipping a given item is worth it once freight is included. Plenty of furniture costs more to move than to replace, and appliances built for a different electrical standard are worth checking before they are loaded rather than after.

Relocation has a compliance dimension separate from the shipping, and our first 90 days checklist covers what has to be registered once you land.

The Short Version

Sint Maarten does not levy a general import duty, and that is a genuine and material advantage over the rest of the region rather than a marketing claim. What it does not mean is that importing is free. Turnover tax on the onward sale, clearance and handling costs, vehicle registration requirements and enforcement controls all remain, and for most importers those add up to the real number.

Businesses get into trouble here in one specific way: by assuming that low landed cost means low tax, pricing accordingly, and absorbing the turnover tax out of margin across an entire chain.
