About ROSA MARINA FLORES-ALVAREZ
Rosa Marina Flores-Alvarez is a CBP-licensed customs broker based in San Juan, Puerto Rico, operating under filer code NZ5. San Juan serves as the primary port of entry for goods moving into Puerto Rico and functions as a significant transshipment hub for the Caribbean region. Licensed brokers in San Juan handle a wide range of import categories including consumer goods, food and beverage products, pharmaceuticals, and manufactured items arriving primarily from the U.S. mainland, Latin America, and Europe. As an individually licensed broker, Flores-Alvarez is authorized to transact customs business before U.S. Customs and Border Protection on behalf of importers requiring formal entry processing, classification, and cargo release at Puerto Rico's ports.
Rosa Marina Flores-Alvarez is a federally licensed U.S. customs broker holding CBP license filer code NZ5, based in San Juan, Puerto Rico. San Juan is home to one of the busiest ports in the Caribbean and serves as a critical gateway for commercial imports entering Puerto Rico, a U.S. territory subject to all federal customs and trade regulations administered by U.S. Customs and Border Protection.
Importers moving goods through San Juan face the same federal compliance requirements as any U.S. port of entry — including proper HTS code classification using the 10-digit tariff schedule, accurate Importer of Record requirements, and compliance with partner government agencies such as the FDA, USDA, and EPA. A locally licensed broker with knowledge of Puerto Rico's import environment is a practical asset for businesses unfamiliar with the territory's logistics landscape.
Flores-Alvarez, as an individually licensed broker, is positioned to assist commercial importers with customs entry preparation for both formal and informal entry thresholds, continuous customs bond or single entry bond procurement, and ISF 10+2 filing obligations for ocean freight shipments. Importers sourcing goods via ocean container — the dominant freight mode into San Juan — must comply with Importer Security Filing (ISF) requirements well ahead of vessel departure.
San Juan's import mix reflects Puerto Rico's economy: consumer goods, pharmaceuticals, food and beverage products, medical devices, and apparel are among the most commonly cleared commodity categories at this port. Importers moving these goods benefit from working with a broker who understands the specific documentation requirements, admissibility rules, and agency referrals that apply to each category.
For importers evaluating duty recovery options, a licensed broker can also provide guidance on duty drawback programs — including unused merchandise drawback and manufacturing drawback — where applicable to Puerto Rico-based operations. Understanding the distinction between a formal entry and an informal entry, or knowing when Section 321 de minimis treatment applies to lower-value shipments, are areas where a licensed broker adds concrete value.
Importers searching for a customs broker near San Juan, PR, or looking for qualified representation before CBP at the Port of San Juan, can consider Rosa Marina Flores-Alvarez as a licensed professional authorized to handle commercial customs transactions in Puerto Rico.
