Quick Answer: Air freight from the USA to San Salvador (SAL) moves in 1-3 days, and pricing runs on chargeable weight using the IATA 1:6000 volumetric divisor. Your cost depends on origin gateway, weight break, box dimensions and Incoterm. El Salvador applies 13% IVA on the CIF value, with CAFTA-DR duty-free treatment for qualifying US-origin goods.
- Airlines bill the greater of gross weight or volumetric weight: length x width x height in cm, divided by 6000.
- Transit to Monseñor Óscar Arnulfo Romero International Airport (SAL) runs 1-3 days from most US gateways, plus 1-2 days for DGA clearance.
- El Salvador charges 13% IVA on CIF value; qualifying US-origin goods clear duty-free under CAFTA-DR with a valid origin certification.
- The calculator on this page prices your exact boxes, weights and origin ZIP in seconds — no signup, no follow-up calls.
Air cargo to El Salvador is a volume game, not a weight game. Measure your packed cartons before you shop rates, because the tape measure decides the price more often than the scale does.

Go to the calculator →How much does it cost to ship air freight to El Salvador per kilo?
Quick Answer: Air cargo to El Salvador is priced per chargeable kilo, and the rate drops as weight rises. Carriers quote in weight breaks: under 45 kg, 45-100 kg, 100-300 kg, 300-500 kg and 500 kg plus. Your origin gateway, density, commodity and Incoterm move the number more than anything else.
Airlines publish a ladder, not a single number. The first rung is the minimum charge, which applies to very small shipments. Above that, each weight break lowers your per-kilo rate.
| Weight break | How the rate behaves | Typical shipment | Billing note |
|---|---|---|---|
| Minimum charge | Flat fee, no per-kilo benefit | 1-2 small cartons | Courier is often cheaper here |
| Under 45 kg (-45) | Highest per-kilo rate | 3-5 boxes of personal goods | Volumetric usually wins |
| 45-100 kg (+45) | First real rate drop | Spare parts, samples | Worth consolidating into this break |
| 100-300 kg (+100) | Mid-tier rate | One loaded pallet | Pallet height counts in volume |
| 300-500 kg (+300) | Lower rate, pallet pricing | Two pallets | Density matters most here |
| 500 kg and up (+500) | Lowest per-kilo rate | Project or inventory lots | Spot rates negotiated weekly |
What actually drives your per-kilo number
Five factors set the rate before any surcharge is added. Each one is inside your control at booking.
- Origin gateway — MIA, IAH, LAX, JFK/EWR and ORD all price differently to SAL.
- Cargo density — light and bulky cargo pays on volume, which raises the effective cost per real kilo.
- Commodity and HS code — batteries, liquids and aerosols carry dangerous-goods handling.
- Screening status — a first-time shipper with unscreened cargo pays for physical screening.
- Scope — airport-to-airport and door-to-door are two different prices.
Miami carries the deepest capacity into San Salvador. Avianca Cargo, Copa Cargo and American Airlines Cargo all serve the lane, and competition keeps MIA per-kilo rates the lowest in the US market. LAX, JFK and IAH typically route through a hub, which adds a connection and a day.
That is why a "cheapest air cargo to San Salvador" search frustrates people. The headline number is usually a bare base rate. It excludes the fuel surcharge (FSC), security surcharge (SSC), the AWB fee, screening and destination handling at SAL.

Pro Tip
Never price air freight off an average per-kilo figure. Two shipments of the same 100 kg can differ by 60% in cost if one is clothing and the other is machine parts. The air freight calculator El Salvador tool on this page prices your actual dimensions, not an industry average.

Go to the calculator →How do I calculate chargeable weight for a shipment to San Salvador?
Quick Answer: Chargeable weight is the greater of actual gross weight and volumetric weight. For air freight, volumetric weight equals length x width x height in centimeters, divided by 6000. Airlines bill whichever number is higher. Light, bulky cargo — clothing, pillows, plastic goods — almost always pays on volume, not scale weight.
The IATA standard divisor for general air cargo is 1:6000 in centimeters. In inches and pounds, the equivalent is cubic inches divided by 166. Courier express uses a denser 1:5000 divisor, which is one reason courier and air freight quotes rarely match.
Worked example 1: four boxes of clothing
Each box measures 60 x 50 x 40 cm and weighs 12 kg on the scale. The math: 60 x 50 x 40 = 120,000 cm³. Divide by 6,000 and you get 20 kg volumetric per box.
Four boxes weigh 48 kg actual but 80 kg volumetric. You pay on 80 kg. That is the normal outcome for soft goods.
Worked example 2: one standard pallet
A pallet measures 120 x 100 x 150 cm and weighs 280 kg. Volume: 1,800,000 cm³ ÷ 6,000 = 300 kg volumetric.
You pay on 300 kg, which pushes the shipment into the +300 kg weight break and a lower per-kilo rate. Sometimes the volumetric penalty is partly offset by the better break.
Worked example 3: dense machine parts
A 60 x 60 x 60 cm crate holds 100 kg of parts. Volume: 216,000 cm³ ÷ 6,000 = 36 kg volumetric. Gross weight wins, so you pay on 100 kg actual.
Every centimeter of empty air inside your carton converts to billable kilos. Shaving 5 cm off the height of four cartons can remove 10-15 chargeable kilos and sometimes drops you into a cheaper weight break.
Measure the outermost point of the packed piece. Include pallet height, overhang, corner protectors and stretch wrap. The airline remeasures at acceptance with a dimensioning scanner, and their measurement is the one that bills.
What is included and excluded in an air freight quote to El Salvador?
Quick Answer: An airport-to-airport air freight quote covers the base rate per chargeable kilo plus fuel surcharge, security surcharge and the air waybill fee. It usually excludes origin pickup, TSA screening of unknown shippers, El Salvador customs brokerage, DGA duties and IVA, warehouse storage at SAL and final delivery in San Salvador.
Air freight pricing is layered. The base rate is only the first layer. Understanding the rest prevents the invoice shock that ruins first-time import budgets.
| Line item | Airport-to-airport | Door-to-door | Who pays under DAP | Who pays under DDP |
|---|---|---|---|---|
| Origin pickup / trucking | Excluded | Included | Seller | Seller |
| Export documentation / AWB fee | Included | Included | Seller | Seller |
| TSA screening / X-ray | Usually extra | Included | Seller | Seller |
| Base rate + FSC + SSC | Included | Included | Seller | Seller |
| SAL terminal handling | Excluded | Included | Buyer | Seller |
| Almacenaje (storage) at SAL | Excluded | Excluded | Buyer | Seller |
| Customs brokerage / DUCA-F | Excluded | Optional | Buyer | Seller |
| Duty + 13% IVA | Excluded | Excluded | Buyer | Seller |
| Final delivery in San Salvador | Excluded | Included | Seller | Seller |
TSA rules matter at origin. Cargo tendered by an unknown shipper must be physically screened by a certified Indirect Air Carrier (IAC) before it flies. Screening adds cost and often a full day for a first-time exporter.
Beware the silent "all-in" quote
If a quote says "all-in" but never names SAL terminal handling, almacenaje, brokerage or IVA, it is not all-in. Ask for the itemized breakdown in writing before booking. Destination charges in Central America are routinely larger than first-time importers expect.
Cargo terminal and almacenaje charges at SAL airport
Monseñor Óscar Arnulfo Romero International Airport (SAL) handles nearly all commercial air cargo into El Salvador. It sits about 40 km southeast of San Salvador, near Comalapa.
Free time at the bonded warehouse is short. Once it expires, almacenaje is billed per kilo per day, and the meter compounds fast on heavy pallets. Terminal handling is also charged on chargeable weight with a minimum, separate from the airline's rate.
Clearance delays are the number one cause of unplanned cost on this lane. Have the DUCA-F and importer documents ready before the flight lands. Plan around terminal hours and national holidays too — a Friday arrival with incomplete paperwork means weekend storage.
How do Incoterms 2020 change your calculated landed cost?
Quick Answer: Incoterms decide where your cost stops and the buyer's begins. EXW means you pay from the shipper's dock onward. FCA and CPT shift risk at origin handover. DAP delivers to the door with duties unpaid. DDP means the seller clears customs in El Salvador and absorbs the 13% IVA and any duty.
For air shipments, five Incoterms cover almost every real transaction into El Salvador. Pick yours before you request a rate, because the Incoterm changes the number the calculator returns.
| Incoterm | Origin pickup | Airline freight | Files DUCA-F | Pays IVA + duty | Risk in transit |
|---|---|---|---|---|---|
| EXW | Buyer | Buyer | Buyer | Buyer | Buyer |
| FCA (origin airport) | Seller | Buyer | Buyer | Buyer | Buyer after handover |
| CPT / CIP (SAL) | Seller | Seller | Buyer | Buyer | Buyer (CIP: seller insures) |
| DAP (door, San Salvador) | Seller | Seller | Buyer | Buyer | Seller to delivery |
| DDP (door, duties paid) | Seller | Seller | Seller | Seller | Seller to delivery |
DAP — the practical default
DAP works for most commercial sales into El Salvador. The Salvadoran buyer is already registered with the DGA and holds a NIT. They file the DUCA-F through their own agente aduanal and recover IVA as a business credit. You control freight; they control clearance.
DDP — attractive, then expensive
DDP looks clean on a quote sheet. In practice the seller needs a registered importer of record in El Salvador to clear and to recover the 13% IVA. Most US sellers have neither, so the tax becomes a sunk cost and the clearance liability sits offshore.
How long does air freight take from the United States to El Salvador?
Quick Answer: Air cargo from Miami to San Salvador flies in 1-2 days, and most other US gateways land within 2-4 days including the hub connection. Add 1-2 business days for DGA clearance and local delivery. Direct capacity from MIA is the fastest and most frequent option to SAL.
| Origin airport | Routing | Airport-to-airport | Door-to-door estimate |
|---|---|---|---|
| Miami (MIA) | Direct, daily | 1-2 days | 3-4 business days |
| Houston (IAH) | Direct or via MIA/PTY | 2-3 days | 4-5 business days |
| Dallas (DFW) | Via MIA or PTY | 2-3 days | 4-5 business days |
| Los Angeles (LAX) | Via MIA or MEX | 2-4 days | 5-6 business days |
| New York (JFK/EWR) | Via MIA | 2-4 days | 5-6 business days |
| Chicago (ORD) | Via MIA or ATL | 2-4 days | 5-6 business days |
| Atlanta (ATL) | Via MIA or direct | 2-3 days | 4-5 business days |
| Toronto (YYZ) | Via a US hub | 3-5 days | 6-7 business days |

Your region decides your gateway. Florida feeds MIA. Texas and the central states feed IAH. California and the Southwest feed LAX. The Northeast feeds JFK or EWR. The Midwest trucks to ORD or ATL. Canadian shippers route through Toronto or a US hub, which is why price and transit always depend on origin.
Cut-off time is not departure time
Cargo must be at the terminal hours before wheels-up — typically 4-6 hours for general cargo. Missing cut-off costs a full day, sometimes two on weekends. General cargo also moves on the next available flight, not a guaranteed one. Express product books a named flight at a premium.
Plan ahead for peak periods. The November-December Christmas box season fills belly capacity on the MIA-SAL lane, and Mother's Day plus school-start shipments create smaller spikes. Book earlier in those windows.

Go to the calculator →Do I have to pay import taxes on goods shipped by air to El Salvador?
Quick Answer: Yes. El Salvador applies 13% IVA on the CIF value plus duty, and the Dirección General de Aduanas (DGA) collects it at clearance. Import duty depends on the HS code, but most qualifying US-origin goods enter duty-free under CAFTA-DR with a valid origin certification. IVA still applies.
The tax base builds in a fixed order. First CIF value: goods plus freight plus insurance. Then duty by HS code. Then 13% IVA calculated on CIF plus duty, not on the invoice alone.
Worked example of the math
- Start with the commercial invoice value: $3,000 in goods.
- Add air freight of $600 and insurance of $40.
- Get a CIF value of $3,640.
- Apply duty — at 0% under CAFTA-DR, duty is $0.
- Calculate IVA: 13% of $3,640 = $473.20.
Those figures are illustrative math, not a quote. Duty and tax are government charges collected by the DGA. They are never an AB Group Shipping price and never appear on a freight invoice.
CAFTA-DR duty-free treatment is not automatic. The goods must be US- or regional-origin and supported by a certification of origin. A US commercial invoice alone is not proof of origin, and customs will assess full duty without the certification. For deeper background on Salvadoran duty and tax mechanics, see this overview of El Salvador import taxes and duties.
The DUCA-F is the Declaración Única Centroamericana, Formulario Aduanero — the Central American declaration used for regional-origin goods. A licensed Salvadoran agente aduanal files it on the importer's behalf.
Thresholds change — verify them
Low-value shipments and personal effects receive different treatment than commercial cargo, and the thresholds are revised periodically. Confirm current limits with a licensed Salvadoran customs broker, not with a blog post. AB Group Shipping is a freight forwarder, not a customs authority or tax advisor.
What documents are needed to import goods into El Salvador by air?
Quick Answer: You need the Air Waybill (AWB), a commercial invoice (factura comercial), a packing list, and the importer's Salvadoran identifiers — NIT for companies and DUI for individuals. Commercial importers must be enrolled as registro de importador with the DGA. CAFTA-DR shipments also need a certification of origin.
- Air Waybill (AWB) — issued by the airline or consolidator, matching the invoice exactly.
- Factura comercial — unit values, currency, full description and HS codes per line item.
- Packing list — box count, dimensions and weight per piece.
- Certificado de origen — required for CAFTA-DR duty-free treatment.
- Insurance certificate — when the sale is on CIF or CIP terms.
Identifiers decide who can receive the cargo. A registered business uses its NIT. A Salvadoran individual uses a DUI. Commercial volumes require registro de importador with the DGA before the shipment lands.
Four mistakes cause most holds: an invoice value that does not match the AWB, missing HS codes, vague descriptions like "samples" or "gift", and no consignee tax ID. Fix these at origin, not at SAL.
Personal effects follow different rules
Household goods and personal effects clear under a separate regime than commercial cargo. For the reverse lane into the USA, personal effects use US Customs Form 3299.

What cannot fly to El Salvador as air cargo?
Some cargo never boards a passenger aircraft, and some needs a specialist quote instead of an instant rate.
- Dangerous goods under IATA DGR — lithium batteries, aerosols, perfumes, paints and lighters need declaration, certified packing and a specialist quote.
- Prohibited outright — firearms, ammunition, narcotics and counterfeit goods.
- Permit-restricted — medicines and supplements, food of animal origin, agricultural products and telecom equipment.
- Not air cargo at all — vehicles, engines with residual fuel and heavy machinery move by ocean container or RoRo.

Is it cheaper to send cargo to El Salvador by air or by ocean?
Quick Answer: Ocean is cheaper per kilo; air is cheaper per day saved. Courier express wins under roughly 30 kg. Air freight wins from about 30 kg to 300-500 kg when speed matters. Ocean LCL takes over above that range, and FCL becomes the better value past roughly 10-12 CBM.
| Mode | Transit to El Salvador | Billing unit | Minimum charge | Best use case | Break-even range |
|---|---|---|---|---|---|
| Courier express | 2-5 days door-to-door | Volumetric 1:5000 | Per-parcel minimum | Documents, small urgent parcels | Under ~30 kg |
| Air freight | 1-3 days airport-to-airport | Chargeable weight 1:6000 | Airline minimum charge | Spare parts, medical, high-value | ~30 kg to 300-500 kg |
| Ocean LCL | ~2-3 weeks | Per CBM or 1,000 kg revenue ton | 1 CBM minimum typical | Dense, non-urgent cargo | ~1 to 10-12 CBM |
| Ocean FCL | ~2-3 weeks | Per container (20'/40') | Flat per container | Household moves, bulk inventory | Above ~10-12 CBM |
When air wins
Air freight wins whenever the cost of waiting exceeds the freight premium. A stopped production line, a medical order or a seasonal retail restock all justify it. Air also lowers inventory carrying cost and reduces damage exposure, since cargo is handled less and spends days — not weeks — in transit.
When ocean wins
Ocean wins on dense, heavy and non-urgent cargo. Salvadoran imports move through Puerto Acajutla, with some volume routed overland via Puerto Barrios. If your cargo is furniture, building materials or bulk inventory, the two-to-three-week transit is worth the savings.
Compare the ocean side before you commit. Our LCL Shipping Calculator El Salvador: CBM Rates 2026 covers the consolidation alternative by cubic meter.

Go to the calculator →Air freight calculator El Salvador: how do you get instant 2026 rates?
Quick Answer: Enter your origin ZIP, the number of boxes, each box's dimensions and weight, and the delivery point in El Salvador. The calculator on this page computes chargeable weight using the 1:6000 divisor, applies the correct weight break, and returns a live 2026 rate in seconds — no signup, no sales call.
An air freight calculator is a pricing engine, not an estimate generator. It takes your declared dimensions, runs the volumetric math, matches a weight break and returns a bookable number. Accuracy depends on accurate measurements — the airline will verify them at acceptance.
- Select air freight as your mode.
- Enter your origin ZIP code or gateway airport (MIA, IAH, LAX, JFK, ORD).
- Input each carton's length, width, height and weight separately.
- Choose airport-to-airport or door-to-door to SAL or San Salvador.
- Pick your Incoterm — DAP and DDP produce different totals.
- Review the chargeable weight the calculator returns before booking.
Some cargo always needs a manual quote. Single pieces over airline door limits, lithium batteries and other DGR, perishables, firearms-adjacent goods and charter requirements all route to a specialist instead of instant pricing.
Repack, then re-run
Run the calculator once, then repack and run it again. Consolidating six loose cartons into three tight ones usually lowers chargeable weight and can cross a weight break. With thousands of shipments processed across the USA-Latin America corridor, repacking is the single most reliable way clients cut air freight cost.
The same engine prices other long-haul air lanes. See Shipping to Nigeria Calculator: Instant 2026 Rates for an example on a transatlantic route.

Go to the calculator →Air cargo to El Salvador is billed per chargeable kilo, and the rate falls as your shipment crosses each weight break — under 45 kg, 45-100 kg, 100-300 kg, 300-500 kg and 500 kg plus. Your origin gateway, cargo density, commodity and chosen Incoterm decide the final number. Use the calculator on this page to price your exact boxes and origin ZIP in seconds.
Multiply length x width x height in centimeters and divide by 6000 to get volumetric weight, then compare it to the actual scale weight. The airline bills whichever number is higher. A 60 x 50 x 40 cm box weighing 12 kg has a volumetric weight of 20 kg, so you pay on 20 kg.
Miami to San Salvador (SAL) flies in 1-2 days airport-to-airport, thanks to daily direct capacity. Add 1-2 business days for DGA clearance and local delivery, so door-to-door is typically 3-4 business days. Other US gateways route through a hub and usually land within 2-4 days.
Yes. El Salvador charges 13% IVA calculated on the CIF value plus any import duty, collected by the Dirección General de Aduanas at clearance. Most qualifying US-origin goods enter duty-free under CAFTA-DR when a valid certification of origin accompanies the shipment, but IVA still applies. Confirm your HS code treatment with a licensed Salvadoran customs broker.
Ocean is cheaper per kilo, but air saves two to three weeks. Courier express usually wins under about 30 kg, air freight makes sense from roughly 30 kg to 300-500 kg when the cargo is urgent or high value, and ocean LCL or FCL wins above that. Run both modes in the calculator on this page to compare.
You need the Air Waybill, a commercial invoice with HS codes and unit values, a packing list, and the consignee's NIT or DUI. Commercial importers must be registered with the DGA as registro de importador, and a licensed agente aduanal files the DUCA-F declaration. CAFTA-DR duty-free treatment also requires a certification of origin.
