Why Central America in 2026
The region does not have one big driver. Panama trades on logistics and connectivity, Costa Rica on export manufacturing in free zones, and Guatemala and El Salvador on a construction sector that grew strongly in 2025. For a duct shop that means a steady mix of warehouses, plants, offices and public works.
Panama: logistics, data centres and Metro Line 3
The Colón Free Zone, operating since 1948, is described as the largest free port in the Americas and lives mainly on re-exporting goods to Latin America and the Caribbean. A Panamanian law firm reported in July 2026 that the zone recorded more than USD 25 billion in commercial activity in 2025 and is planning a USD 250 million expansion, with a first phase of 36 hectares due to go to tender in 2026. Warehouses, showrooms and offices there need ventilation and air conditioning.
Panama is also a connectivity hub. In February 2026 the Colombian business daily La República counted 14 operating data centre facilities in Panama, served by 8 submarine cables. Electrical rooms, offices and support areas around data halls need sheet metal; see our data centre duct manufacturing guide. In Panama City, Metro Line 3 is a 24.6 km elevated monorail with 11 stations between Albrook and Ciudad del Futuro in Arraiján, with substantial completion targeted for October 2028.
Costa Rica: medical device plants and cleanrooms
Costa Rica's exports reached a record USD 35,243 million in 2025, and medical devices were the largest item at 31%, more than USD 10,800 million and 25% up on 2024, according to figures from PROCOMER and the central bank reported in April 2026. Many of these plants operate under the free zone regime. New entrants keep arriving: in April 2026 the US contract manufacturer Switchback Medical announced a plant of over 1,600 m² in the Coyol Free Zone with a cleanroom of about 350 m², and a second site in the Evolution Free Zone in Grecia planned for 2027. Growth slowed sharply in 2026, to about 2% up to July against 34% a year earlier, so treat this as steady fit-out and expansion work rather than a boom.
Cleanroom and controlled-environment work needs tightly sealed rectangular duct, clean internal surfaces and often stainless sections. Our cleanroom duct guide and galvanised vs stainless comparison cover what that means in the shop.
Guatemala
The Guatemalan construction chamber (CGIC) said the sector grew about 8.5% in 2025 and projected growth of about 4.7% for 2026, slower but still positive. In and around Guatemala City, offices, retail, logistics and industrial buildings are the everyday work for duct shops there.
El Salvador
The Salvadoran construction chamber Casalco estimated public and private construction investment at about USD 3,000 million in 2025 and said in March 2026 that 2026 could close between USD 3,500 and 4,000 million. The government's 2026 public investment programme exceeds USD 2.68 billion across 235 projects, with the Pacific International Airport in La Unión as the largest single item. Airports, hotels and public buildings all need ductwork.
Honduras
San Pedro Sula is the country's main industrial centre, with a large apparel manufacturing (maquila) base. Factory ventilation, extract and office fit-outs are the typical duct jobs.
Standards and codes for ductwork in Central America
None of the five countries has a national duct construction standard that replaces the American documents. A duct shop builds to what the mechanical specification names, and for sheet metal ductwork that is usually SMACNA, inside each country's own seismic, electrical and fire rules.
- SMACNA HVAC Duct Construction Standards: the usual reference for gauges, seams, transverse joints, reinforcement and hangers, on US-designed and local projects alike. See our gauge chart and hangers and supports guide.
- ASHRAE: ventilation and energy design commonly follows ASHRAE standards such as 62.1, with ASHRAE 170 used for healthcare ventilation. These set airflows and duct sizes rather than construction details.
- ISO 14644: cleanroom classification for the medical device and pharmaceutical plants in Costa Rica's free zones. Leakage and sealing matter more than gauge; see our air leakage classes guide.
- Costa Rica: the officially recognised seismic code is the Código Sísmico de Costa Rica 2010, revision 2014. The CFIA approved the text of a 2025 revision in November 2025, with publication pending when last reported. The electrical code is NFPA 70, made official by Decree 36979-MEIC, with the 2020 edition applying since July 2024.
- Panama: structural and seismic design follows the REP-2021 regulation adopted by the Junta Técnica de Ingeniería y Arquitectura, in force from 30 April 2023.
- Guatemala: the AGIES NSE standards, 2024 edition, published through CONRED. NSE 8 covers the design of non-structural elements, which is where duct supports and bracing fall.
- El Salvador and Honduras: each has its own structural and construction regulations. In practice ductwork is built to SMACNA and to the project specification, so check what your client names.
Importing duct machinery into Central America
Every country charges VAT on imports, and the rates differ:
- Panama: ITBMS at 7%, charged on the CIF value plus import duty and handling charges.
- Costa Rica: IVA at 13% on domestic and imported goods. Customs duties range from 1% to 15% ad valorem depending on the tariff line.
- Guatemala: IVA at 12% on imports. Import duty (DAI) follows the Central American tariff system with rates from 0% to 20%.
- El Salvador: IVA at 13% on the customs value. Certain machinery imported by registered taxpayers as fixed assets is exempt.
- Honduras: sales tax (ISV) at 15%, but machinery and equipment are among the exempt goods. Duties generally range from 0% to 15%.
Guatemala and El Salvador apply import duty from the common Central American tariff system. Many capital goods lines carry low or zero duty, but we could not confirm the rate for duct forming and folding machines, which usually fall under HS heading 8462, so ask your customs broker to classify the machine before you budget.
Do not assume CAFTA-DR makes a machine duty free. The agreement links the United States with Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and the Dominican Republic, and its preferences apply only to goods that meet its rules of origin. Panama has a separate trade promotion agreement with the United States. Free zone regimes in Costa Rica and Panama can suspend duty and tax for qualifying companies; check the conditions with a tax adviser. Taokron machines are CE marked with a Declaration of Conformity and ship with electrical diagrams and component lists. Tell us your nearest port when you ask for a quotation; our importing guide covers the general paperwork.
Power supply: 60 Hz everywhere, three phase voltages vary
All five countries run at 60 Hz, with 120 V single phase outlets. Three phase supplies are less uniform. Published references list 120/208 V and 277/480 V systems in Panama, 208 V and 480 V in Guatemala, and 208 V to 480 V in Honduras, while references for Costa Rica and El Salvador disagree with each other.
The safe approach is simple: measure the three phase voltage at your workshop and tell us. We wire motors, drives and the control transformer to suit, and a 50 Hz machine should never be installed without that change. See also duct machine voltage and frequency by country.
Typical shop set-ups and the machines that fit
Contractor shop, rectangular duct for fit-outs
Most Central American duct shops start as the workshop of an HVAC installer making rectangular duct for offices, shops, hotels and warehouses. The core of that shop is a Rectangular Duct Line II SBAL-II or an Auto Duct Line SBAL-III, which decoils, levels, beads, notches, shears and folds in one pass. Add a Pittsburgh lockformer (SBLC series) for longitudinal seams, a TDF flange forming machine for transverse joints, a duct zipper to close seams quickly and a pneumatic folder for fittings and short runs. That set covers straight duct, TDF joints and simple fittings with a small crew.
Volume shop for warehouses, plants and cleanrooms
Shops supplying logistics buildings in Panama, plant expansions in Costa Rica's free zones or large commercial jobs in Guatemala City need output and repeatable quality. The Auto Duct Line SBAL-V runs from coil to finished panel with less handling. Pair it with an auto corner making machine and a pneumatic corner mounting machine to finish TDF corners at line speed, a Plasma Cutter SBPC1550 for nested fittings, and a hydraulic folder for heavier gauges and long bends. For cleanroom work, tight seams and consistent corners are what pass the leakage test.
Round duct
Spiral duct suits exposed ceilings, warehouses, car parks and industrial extract. The Spiral Tubeformer SBTF-1500 or SBTF-1602 forms round duct, and the Spiral Duct Flanging Machine SBFB-1600 turns flanges on duct ends. For a real example, see Kavanagh Industries in Sydney, which added an SBTF-1602 in October 2026.
Stainless and industrial work
For stainless extract in plants and laboratories, the stainless duct forming machine and the Automatic Stitchwelder SB-ZF1500 cover seams that a lock cannot.
Labour and space
Wages and labour rules differ a lot between Panama, Costa Rica and the northern countries, so we do not quote figures here; check current minimum wages and payroll costs with a local adviser. The general point holds across the region: skilled sheet metal workers are harder to find than general labour, and an auto duct line replaces much of the manual marking, cutting, notching and folding, so a small crew can supply several sites.
On space, the auto duct line is the longest item, with coil racks at one end and a run-out table at the other. Ask us for a layout drawing based on your building before you sign a lease, and leave room for coil deliveries, finished duct storage and truck loading. Location follows the work: near the Colón and Panama City logistics corridor, the free zones of Costa Rica's Central Valley, Guatemala City, the San Salvador metropolitan area or the Sula valley in Honduras. Our factory layout guide has worked examples.

FAQ
Which ductwork standards are used in Central America?
There is no regional duct construction standard. Mechanical specifications in Panama, Costa Rica, Guatemala, El Salvador and Honduras commonly call for sheet metal ductwork to the SMACNA HVAC Duct Construction Standards for gauges, seams, joints, reinforcement and hangers, with ASHRAE standards used for ventilation and energy design and ISO 14644 for cleanroom classification. National rules sit around that: Costa Rica's Seismic Code (CSCR 2010, revision 2014) and its electrical code based on NFPA 70; Panama's structural design regulation REP-2021; and Guatemala's AGIES NSE 2024 standards, including NSE 8 for non-structural elements. Always build to the documents named in the project specification.
What voltage and frequency do duct machines need in Central America?
All five countries run at 60 Hz, with 120 V single phase outlets. Three phase supplies vary by site: published references list 120/208 V and 277/480 V in Panama and 208 V to 480 V in Guatemala and Honduras, while references for Costa Rica and El Salvador disagree. Measure the three phase voltage at your workshop and tell us, and we wire the motors, drives and control transformer to suit.
What taxes apply when importing duct machinery into Central America?
Value added tax is charged on imports in all five countries: ITBMS at 7% in Panama, IVA at 13% in Costa Rica, 12% in Guatemala and 13% in El Salvador, and ISV at 15% in Honduras. Customs duty depends on the full tariff subheading; Guatemala and El Salvador, for example, apply the common Central American tariff system. Some machinery is exempt from VAT, for example in Honduras and for certain fixed-asset machinery in El Salvador, so ask your customs broker to classify the machine and confirm duty and tax before you budget.
Does CAFTA-DR make imported duct machines duty free?
Not automatically. CAFTA-DR links the United States with Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and the Dominican Republic, and its preferences apply only to goods that meet its rules of origin. Panama has a separate trade promotion agreement with the United States. A machine made outside those agreements pays the normal rate for its tariff line, which for many capital goods is low, but confirm the exact rate with your broker.
Where is ductwork demand in Central America coming from in 2026?
In Panama, logistics and distribution around the Colón Free Zone, data centres served by the country's submarine cables, and Metro Line 3. In Costa Rica, medical device plants in free zones, which need cleanrooms and controlled ventilation. In Guatemala and El Salvador, a growing construction sector led by commercial, residential and public works, and in Honduras, industrial work around San Pedro Sula.
Which machines should a new Central American duct shop start with?
A contractor shop making rectangular duct for offices, shops and fit-outs usually starts with a rectangular duct line or auto duct line, a Pittsburgh lockformer, a TDF flange former and a folder. Add a spiral tubeformer when round duct becomes regular work, and a plasma table when fittings volume grows. Send your duct sizes, gauges and monthly output and a Taokron engineer will propose a machine set within 12 hours.
