Exporting LPG and Propane to the US — Agricultural and Industrial Distributors

Liquefied petroleum gas (LPG) and its primary constituent propane are essential feedstocks for US agricultural and industrial distributors. In agriculture, propane powers crop drying, irrigation pumps, and livestock heating; in industry, it fuels forklifts, process heating, and standby power generation. The United States is both the world’s largest producer and consumer of propane, yet seasonal demand spikes—especially during fall harvest and winter heating—create consistent import opportunities. Latin American suppliers, particularly from the US Gulf Coast’s natural gas liquids (NGL) corridor and emerging producers in Colombia and Peru, offer competitive volumes for US distributors seeking to diversify supply. This page details the product grades, supplier landscape, buyer types, import requirements, and pricing context for exporting LPG and propane to the United States.

Product Specifications and Grades

Propane traded internationally falls under the specification HD-5 (Heavy Duty-5), defined by ASTM D1835 and GPA 2140 standards. HD-5 propane must contain at least 90% propane and propylene, with a maximum of 5% propylene and a vapor pressure not exceeding 208 psig at 100°F. Commercial-grade propane (ASTM D1835-21) allows lower purity, typically 85% propane minimum, and is used in less demanding applications such as space heating and cooking. For industrial buyers, propane with sulfur content below 120 ppm by weight is preferred to meet emission controls and protect sensitive equipment. LPG as a broader category includes propane, butane, and mixtures; US importers typically specify pure propane (C3) or propane-butane blends for seasonal flexibility. The Energy Information Administration (EIA) notes that US propane demand peaks in October–December for crop drying and space heating, making winter-grade propane with lower butane content critical to maintain vapor pressure in cold climates. Exporters must provide a product data sheet showing PONA analysis (paraffins, olefins, naphthenes, aromatics), vapor pressure, and sulfur content to satisfy US buyers’ quality assurance protocols.

Latin American and African Supplier Landscape

Latin America is a net exporter of LPG, driven by associated gas production from oil fields. The US itself is the dominant global propane exporter, but Latin American suppliers—particularly in Colombia, Peru, and Trinidad and Tobago—offer alternative sources for US distributors seeking shorter supply chains or spot cargoes. Colombia’s LPG production averaged 1.2 million metric tons annually from 2020 to 2023, with state energy company Ecopetrol and private operators such as Frontera Energy supplying propane via the Cartagena export terminal. Peru’s Camisea gas complex produces propane and butane as byproducts, with exports directed primarily to the US West Coast. Trinidad and Tobago, a major LNG exporter, also produces propane from its petrochemical sector; Phoenix Park Gas Processors Limited operates an NGL fractionation plant with 50,000 barrels per day capacity, exporting propane to the US Gulf Coast. In Africa, Nigeria and Angola have growing LPG production, but logistics infrastructure and quality consistency remain barriers for US distributors. The US International Trade Commission (USITC) reported that US imports of propane from Latin America totaled 12.3 million barrels in 2023, representing 18% of total US propane imports. Suppliers must demonstrate reliable terminal storage, marine loading capabilities for VLGCs (very large gas carriers), and compliance with US Coast Guard regulations for LPG tankers.

US Buyer Types — Who Buys, How They Procure, What Specs Matter

US agricultural and industrial distributors buy propane through two primary channels: (1) wholesale spot purchases from import terminals or storage caverns, and (2) term contracts with producers or traders. Agricultural distributors typically serve cooperatives, grain elevators, and livestock operations; they require HD-5 propane with low sulfur (<30 ppm) to protect propane-powered grain dryers and irrigation engines. Industrial distributors serve manufacturing plants, warehouses, and fuel retailers; they may accept commercial-grade propane for process heating but demand vapor pressure tolerance for year-round use. Procurement is often seasonal: agricultural buyers ramp up orders in August–October for harvest, while industrial buyers maintain steady monthly volumes. The National Propane Gas Association (NPGA) estimates that the US propane distribution market comprises over 3,000 retail dealers, with the top 20 controlling about 40% of sales. Distributors typically require suppliers to provide product quality certificates, cargo weight documentation, and delivery within 10–15 days of bill of lading. Price is typically indexed to the Mont Belvieu propane price (published by OPIS) plus a premium for freight and quality differentials. For exporters, understanding the end-user’s application—whether for crop drying, forklift fuel, or peak shaving—determines the grade and contract terms needed.

Certifications and Import Requirements

All propane imported into the United States must comply with federal safety and environmental regulations. The US Department of Transportation (DOT) requires that propane cargoes be transported in DOT-specification cargo tanks or ISO containers, with a current hydrostatic test certificate. The Environmental Protection Agency (EPA) mandates that propane sold as motor fuel must meet the sulfur content limits under the Renewable Fuel Standard (RFS) if used for on-road vehicles; however, most agricultural and industrial uses are exempt. For marine shipments, the US Coast Guard requires that LPG tankers have a valid International Gas Carrier (IGC) Code certificate and a cargo compatibility letter from the USCG. Exporters must provide a Certificate of Analysis (COA) from an accredited laboratory showing compliance with ASTM D1835 or GPA 2140. Additionally, the US Customs and Border Protection (CBP) requires a formal entry filing with the Harmonized Tariff Schedule code 2711.12 (liquefied propane) or 2711.13 (liquefied butane) and a manifest from the shipping line. For suppliers in Latin America, the US has a free trade agreement with Colombia that eliminates tariffs on propane imports; Peru also benefits from the US–Peru Trade Promotion Agreement. African suppliers face standard MFN tariffs of 0.5% for propane, but must navigate the African Growth and Opportunity Act (AGOA) provisions for duty-free access if eligible. The American Petroleum Institute (API) publishes recommended practices for LPG storage and handling (API 2510), which US buyers often reference in contracts.

Pricing and Lead Time Context

Propane prices are highly volatile, driven by crude oil prices, NGL supply from US shale basins, and seasonal demand. The Mont Belvieu non-TET propane price (the benchmark for Gulf Coast spot trades) averaged $0.89 per gallon in 2023, ranging from $0.65 in January to $1.15 in October. For Latin American exports, the delivered price to US Gulf Coast terminals typically adds $0.10–$0.20 per gallon for freight and insurance, depending on the origin port and vessel size. Lead time from Colombia’s Cartagena terminal to Houston is 5–7 days by VLGC; from Peru’s Pisco terminal to Los Angeles, 8–10 days. African suppliers face longer lead times—15–20 days from Nigeria to the US Gulf Coast—and higher freight costs, which can add $0.15–$0.25 per gallon. US distributors typically require 30-day forward pricing for term contracts, with price adjustments based on the Mont Belvieu index plus a fixed differential. Spot cargoes are often traded on a CIF (cost, insurance, freight) basis, with payment via irrevocable letter of credit at sight. The US Energy Information Administration (EIA) projects that US propane demand will grow at 1.5% annually through 2030, driven by agricultural expansion and industrial fuel switching from diesel to propane. Exporters should monitor the US propane inventory reports published weekly by the EIA, as inventory levels directly influence spot prices and distributor buying behavior.
