International Trade Documents Checklist: What You Need for Every Cross-Border Deal

Every commercial import/export shipment requires a minimum of three documents:

1. Commercial Invoice — The core transaction document. Must include: seller and buyer full names/addresses, invoice date and number, full product description, HS code (Harmonized System tariff code), quantity and unit of measure, unit price and total value, currency, Incoterms (e.g., FOB Santos, CIF Los Angeles), and country of origin.

2. Packing List — Itemizes every carton/pallet: number of packages, individual and total gross/net weights, dimensions, and how goods are packaged. Customs uses this to verify the commercial invoice.

3. Bill of Lading (ocean) or Airway Bill (air) — The transport contract issued by the carrier. Serves as receipt of goods, evidence of the transport contract, and (for B/L) document of title transferable to the buyer.

A Bill of Lading (B/L) is one of the most important documents in international trade. Issued by the shipping line when cargo is loaded, it serves three functions simultaneously:

1. Receipt of goods — confirms the carrier received the cargo in the described condition.
2. Transport contract — defines the shipment terms (port of loading, port of discharge, freight terms).
3. Document of title — in its "negotiable" form, the B/L can be endorsed and transferred; the holder of the original B/L can claim the cargo.

Key distinction: Negotiable B/L (consigned "to order") is used in Letter of Credit transactions where title changes hands. Non-negotiable (Straight) B/L is consigned directly to the buyer — faster but less secure for the seller. For express trade, Sea Waybills are non-negotiable alternatives that don't require the original for cargo release.

A Certificate of Origin (CO) is an official document certifying the country where the goods were produced or substantially transformed. It is required when:

• The destination country applies preferential tariff rates based on origin (e.g., GSP, FTA benefits)
• The importing country requires it for customs clearance (many countries do)
• The buyer's Letter of Credit requires it

Two types exist: Non-preferential CO (general; confirms origin but grants no preferential duty rate) and Preferential CO (e.g., Form A for GSP; grants reduced tariffs at destination).

In Brazil, Certificates of Origin are issued by authorized chambers of commerce (FUNCEX, FIESP, CACB) or government bodies. Processing typically takes 1–3 business days. Always request the CO before shipment — retroactive issuance is complicated or impossible in most jurisdictions.

A Phytosanitary Certificate is issued by the national plant protection authority (in Brazil: MAPA) and certifies that agricultural products are free from pests and plant diseases and meet the importing country's phytosanitary requirements.

Required for: fresh fruits and vegetables, grains and seeds, coffee, soybeans, wood and timber products, cut flowers, and any plant-derived product that may carry biological risk.

Failure to provide a valid phytosanitary certificate for regulated products results in shipment hold, fumigation at importer's cost, or destruction. Processing time in Brazil is typically 3–7 business days from MAPA inspection. Request early — this is one of the most common documentation bottlenecks in Brazilian agricultural exports.

A Letter of Credit (L/C) is a payment instrument issued by the buyer's bank that guarantees payment to the seller, provided the seller presents compliant documents within the agreed timeframe. It is the gold standard for risk mitigation in international trade.

Use an L/C when: you're dealing with a new counterparty for the first time; the buyer's country has political or currency risk; the transaction value is significant (typically $50K+); or either party cannot independently verify the other's creditworthiness.

Key types: Irrevocable Confirmed L/C — maximum security for the seller; confirmed by seller's local bank. Standby L/C — acts as a payment guarantee, only drawn upon if buyer defaults. Documentary Collection (D/P, D/A) — lighter and cheaper than L/C, but provides less protection.

For SME trades between known partners, open account (T/T wire transfer) is common — 30–50% advance with balance against shipping documents.

The Harmonized System (HS) code is a 6-digit international product classification code developed by the World Customs Organization (WCO). All countries use HS codes to classify goods for customs and tariff purposes — with each country adding additional digits (US uses 10-digit HTS codes; Brazil uses 8-digit NCM codes).

Finding the right HS code matters because it determines: duty rates, import/export licensing requirements, trade statistics, and eligibility for preferential tariff treatment.

How to find your HS code:
1. Use the USITC HTS database (hts.usitc.gov) for US import classification
2. Use Brazil's MDIC/SISCOMEX for NCM (Brazilian HS) classification
3. Ask your customs broker — misclassification is a major compliance risk

Common Brazilian export HS codes: Coffee green 0901.11, Soybeans 1201.90, Iron ore 2601.11, Beef frozen 0202.30, Aircraft 8802.40.

Brazilian exports have a few country-specific requirements:

• Nota Fiscal (NF-e) — Brazilian electronic fiscal invoice required for all goods leaving the factory/warehouse. Must be issued before the cargo moves to port.
• DU-E (Declaração Única de Exportação) — replaces the old RE/DSE system. Filed electronically in SISCOMEX (Brazil's customs system) before shipment. Your customs broker handles this.
• LPCO (Licença, Permissão, Certificado ou Outros Documentos) — product-specific permits; MAPA issues these for agricultural products, ANVISA for health-regulated items, IBAMA for forestry/natural resource products.
• REC (Registro de Exportação) — for certain controlled products including sugar, soybeans, coffee; may be required depending on export quotas or bilateral agreements.

A licensed Brazilian Despachante Aduaneiro (customs broker) is highly recommended — SISCOMEX is complex and errors result in holds and fines.
