From incoterms to customs classification — chemical trade terms decoded for US-LATAM-Africa corridors

In the cross-border trade of chemicals between the United States, Latin America, and Africa, precise terminology is critical for compliance, safety, and efficient logistics. Whether you are sourcing industrial solvents from Brazil, exporting agricultural chemicals from the U.S. to Nigeria, or managing hazardous material shipments across the Panama Canal, understanding the language of chemical manufacturing and trade ensures smooth operations and regulatory adherence. This glossary defines the essential terms every trader, manufacturer, and logistics professional needs to navigate this complex sector.

Raw Materials & Feedstocks

Feedstock refers to the raw material used as an input in a chemical manufacturing process. In US-LATAM-Africa trade, common feedstocks include crude oil derivatives (like naphtha), natural gas, and agricultural products such as corn or sugarcane. For example, Brazilian ethanol (etanol) is a key feedstock for U.S. bio-based chemical production, while African palm oil serves as a feedstock for oleochemicals.

Bulk Chemicals are large-volume, low-cost chemical products typically produced in continuous processes. Examples include sulfuric acid, caustic soda, and methanol. These are often shipped in tank containers or bulk vessels between U.S. Gulf ports and Latin American or African ports, where they serve as building blocks for downstream industries.

Commodity Chemicals are standardized chemicals with little differentiation between producers, traded primarily on price. They include ethylene, propylene, and benzene. Trade in commodity chemicals between the U.S. and Latin America is heavily influenced by shale gas availability in the U.S., while Africa imports many commodity chemicals for local manufacturing.

Specialty Chemicals are high-value, low-volume chemicals designed for specific applications, such as adhesives, coatings, or water treatment agents. These require precise formulations and often involve intellectual property protections. U.S. specialty chemical exports to LATAM and Africa command premium prices but face stricter customs classification.

Oleochemicals are chemicals derived from natural fats and oils, such as fatty acids, glycerin, and fatty alcohols. Latin America, particularly Indonesia and Malaysia (though also Brazil), is a major producer of palm and soybean oils used in oleochemical manufacturing. African palm oil is increasingly exported to the U.S. for this purpose.

Manufacturing Processes & Equipment

Batch Processing is a manufacturing method where chemicals are produced in discrete quantities, or batches, rather than continuously. This is common for specialty chemicals and pharmaceuticals. In trade, batch-processed chemicals often have shorter shelf lives and require careful temperature control during shipping.

Continuous Processing involves the uninterrupted production of chemicals, typically for high-volume commodity chemicals. This method offers economies of scale and is common in U.S. Gulf Coast refineries. Shipments from these facilities to LATAM and Africa are often scheduled on long-term contracts.

Cracking is a refining process that breaks down large hydrocarbon molecules into smaller, more valuable ones, such as ethylene and propylene. Ethane cracking (using ethane from U.S. shale gas) has made the U.S. a competitive exporter of these building blocks to Latin America and Africa.

Distillation separates mixtures based on differences in boiling points. It is fundamental to petrochemical refining and solvent production. In trade, distillation specifications (e.g., boiling point ranges) are critical for customs classification and quality assurance.

Catalyst is a substance that increases the rate of a chemical reaction without being consumed. Catalysts are themselves traded as specialty chemicals; U.S. companies export catalysts for fertilizer production to Latin America and for refining to Africa.

Reactor is the vessel where chemical reactions occur. The type of reactor (e.g., batch, continuous stirred-tank, or plug flow) affects product quality and yield. Trade in reactor technology and replacement parts is a niche but important segment between the U.S. and emerging markets.

Regulatory & Compliance Terms

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the European Union's chemical regulation, but it impacts global trade. U.S. exporters to Africa and LATAM must ensure their chemicals comply with REACH if the final destination is Europe, or with local equivalents such as Mexico's COFEPRIS or Brazil's ANVISA.

SDS (Safety Data Sheet) (hoja de datos de seguridad in Spanish, ficha de dados de segurança in Portuguese) is a document that provides information on the properties, hazards, handling, and emergency measures for a chemical. Every chemical shipment between the U.S., LATAM, and Africa must include an SDS in the language of the destination country.

GHS (Globally Harmonized System) is a UN system for classifying and labeling chemicals. While many countries have adopted GHS, implementation varies. U.S. exporters must ensure labels and SDSs meet local GHS requirements in Mexico, Brazil, or South Africa to avoid customs delays.

HTS (Harmonized Tariff Schedule) codes classify chemicals for customs purposes. Correct classification is vital because duty rates and regulatory requirements differ widely. For example, a pesticide may fall under a different HTS code depending on its formulation, affecting trade costs between the U.S. and LATAM.

TSCA (Toxic Substances Control Act) is the U.S. law governing new and existing chemicals. Exporters to the U.S. must ensure their chemicals are listed on the TSCA Inventory. Similarly, countries like Mexico and Brazil have their own chemical inventories (e.g., Brazil's Inventário de Produtos Químicos).

Logistics & Shipping Terms

IMO (International Maritime Organization) Classification categorizes dangerous goods for maritime transport. Chemicals are assigned IMO classes (e.g., Class 3 for flammable liquids, Class 8 for corrosives). Proper classification determines packaging, stowage, and shipping documentation for U.S.-LATAM-Africa routes.

Tank Container is a specialized intermodal container designed for transporting bulk liquids, including chemicals. These are commonly used for shipping chemicals from U.S. Gulf ports to Latin America and Africa, offering flexibility for multimodal transport.

ISO Tank is a specific type of tank container built to ISO standards. ISO tanks are widely used for hazardous chemicals, as they meet international safety requirements and can be stacked on ships or trucks.

Bulk Liquid Shipping refers to the transport of large volumes of liquid chemicals in specialized vessels (chemical tankers). This is common for commodity chemicals like caustic soda or methanol shipped from U.S. to Brazil or from Nigeria to the U.S.

Dangerous Goods Declaration (declaración de mercancías peligrosas) is a shipping document required for any hazardous chemical shipment. It must include the UN number, proper shipping name, class, and packing group. Errors in this declaration are a leading cause of customs holds in LATAM and African ports.

Trade & Commercial Terms

Incoterms are international trade terms that define responsibilities between buyer and seller. For chemical shipments, common Incoterms include FOB (Free on Board) for bulk cargo and CIF (Cost, Insurance, and Freight) for containerized goods. Understanding Incoterms is essential for allocating risk in cross-border chemical deals.

Letter of Credit (LC) (carta de crédito) is a payment method often used in chemical trade to mitigate risk between unfamiliar parties. U.S. exporters to Africa frequently require LCs due to currency volatility and credit concerns.

Spot Market is where chemicals are traded for immediate delivery, as opposed to long-term contracts. Spot prices for commodity chemicals like methanol can fluctuate dramatically based on supply disruptions in the U.S. Gulf or demand spikes in Latin America.

Contract Manufacturing (maquila in Spanish) involves a company hiring another to produce chemicals under its brand. This is common in the U.S.-Mexico trade, where U.S. firms contract Mexican manufacturers for cost-effective production of specialty chemicals.

Certificates of Analysis (CoA) are documents that verify the chemical composition and quality of a shipment. They are critical for specialty chemicals and are often required by customs in LATAM and Africa to confirm that the product meets import standards.
