San Antonio bunker prices
CLSAI · CL · Major bunkering hub
Arithmetic on the 6 nearest ports where a price was observed, weighted by distance. Nobody has quoted this at San Antonio, and it carries nothing about the barge, the volume or your credit — which is what actually sets the number.
Why there is no assessment here yet
Only 0 observations in the last 72 hours. We publish an assessment from 3 or more.
No price is published for this port yet. Our assessment is built only from what we observe here — prices suppliers submit to us, quotes received against requests raised here, and stems that close — so it appears once this port has traffic. A request raised now still reaches suppliers; it does not wait for an index.
Our own assessment, computed from observations made on this platform: prices submitted by suppliers, quotes received against requests raised here, and stems that closed. Weighted by how firm each observation is (a closed stem counts three times a list price), by how recent it is, and by parcel size. Values more than 15% from the median are excluded. No third-party assessment is used as an input, and no number is published from fewer than three observations or fewer than two independent sources.

Taking fuel at San Antonio
Operational notes, from the port authority and the suppliers’ own published documents. Checked 2026-09-02.
Bunkers at San Antonio are delivered by barge and by truck; no pipeline bunkering is offered. Delivery is available to vessels at berth, with the port's sheltered basin (STI terminal acts as breakwater) supporting operations; anchorage delivery is not confirmed. Pilotage is compulsory and tug assistance is available. Marine fuels offered include MGO, VLSFO and HSFO, plus lubricants (Castrol, Gulf, Mobil, Shell, Total). Suppliers/agents should be nominated in advance; a 24-hour advance request via the maritime authority's SIAN system is required for bunkering operations under Directemar rules (circular O-31/002 governs safe bunkering transfer procedures). San Antonio is NOT in an ECA, so standard IMO global sulphur limits (0.50% sulphur) apply unless the vessel's own compliance plan requires otherwise. No verified night-delivery restrictions or weather limits were found; confirm with the port authority or agent before fixing a stem.
- typical stem time / pumping rates for bunker barges
- night delivery allowed?
- anchorage bunkering availability
- bunker barge capacity
- weather/sea-state limits
Ask the supplier to confirm these before you fix a stem on them.
The working behind the estimate above.
Those are prices at those ports, not at San Antonio, and the distances are great-circle rather than routed. The estimate above is arithmetic on them — it carries no information about the barge, the volume or your credit, which is what actually sets the number. A request is the only way to get a real one.
Indicative only. Typical stem time here is about 8 hours alongside.

Not an offer to sell — a firm price exists only once a supplier has quoted.
A lower headline price at another port is not automatically a saving. Deviation burns fuel and charter hire, and a bunker-only call costs port time.
San Antonio bunkering FAQ

- Whether a port is cheap for your vessel depends on the deviation cost, not just the headline price — reaching a cheaper port costs charter hire and fuel.
