Rates change annually (typically in January); the figures below reflect January 2024 pricing. Always verify at usps.com or your local Post Office before mailing.

Standard Letter Mail (First-Class Mail International)

For letters, postcards, and flats up to 15.99 oz (453 g). No tracking (except Registered Mail add-on). Delivery: 1–3 weeks typically.

Tracked & Faster Services

Registered Mail (Maximum Security)

For valuable/irreplaceable items. Chain-of-custody tracking. Slowest (4–6+ weeks).

Critical Requirements for Brazil

• Customs Form: PS Form 2976 (green customs declaration) for First-Class letters/flats < 16 oz. PS Form 2976-A (commercial invoice) for packages/merchandise. Declare contents accurately.
• CPF/CNPJ Number: Brazilian recipient's tax ID (CPF for individuals, CNPJ for companies) must be on the customs form. Without it, Correios (Brazil Post) will hold the item, charge storage fees, and may return it.
• Prohibited/Restricted: Cash, coins, jewelry, precious metals, lithium batteries (loose), perfumes (aerosol), medications (without ANVISA permit), used clothing (restricted).
• Address Format: Write in Portuguese format: Recipient Name, Street Name + Number + Apt, Neighborhood, City - State Abbreviation, CEP (postal code), BRAZIL. Example:
  João Silva
  Rua XV de Novembro, 1234, apto 506
  Centro
  Curitiba - PR, 80020-310
  BRAZIL

Brazil-Specific Reality Check

Correios charges the recipient Import Tax (II) = 60% of declared value + shipping for items over $50 USD (including shipping), plus state ICMS tax (~18%). Postal handling fee (~R$150). Inform your recipient. For gifts, the $50 exemption applies only if sent person-to-person, declared as "gift," and value < $50.
