William Leon is a federally licensed customs broker serving the Palmetto Bay and greater Miami, Florida area under CBP filer code BSF. With Miami consistently ranking among the top U.S. ports of entry by cargo volume, a locally based customs broker with direct knowledge of Miami International Airport (MIA) and PortMiami operations provides meaningful advantages for importers across South Florida and beyond.
For first-time importers, understanding how commercial entry works under U.S. customs law can be daunting. From determining the correct HTS code for your merchandise — including complex categories like electronics or consumer goods — to completing CBP Form 3461 for immediate delivery, the entry process involves multiple regulatory steps that must be executed accurately to avoid delays, exams, or penalties. William Leon's licensure under 19 USC authority reflects the federal standard required to transact customs business on behalf of importers.
One area of significant value for established importers is the duty drawback program under 19 USC 1313. Duty drawback refunds allow eligible businesses to recover up to 99% of duties paid on imported goods that are subsequently exported or destroyed. Filing a proper duty drawback claim — often referred to as "how to file duty drawback" — requires precise documentation and adherence to CBP timelines. A licensed broker familiar with these provisions can help importers identify eligible shipments and prepare compliant claims.
Additionally, importers shipping ocean freight into the U.S. are required to submit an Importer Security Filing (ISF), commonly called 10+2, at least 24 hours before cargo is loaded at the foreign port. Failures in ISF filing can result in substantial liquidated damages. Securing a continuous customs bond — rather than a single-entry bond — is typically recommended for importers with multiple annual shipments, as it provides ongoing coverage across all entries.
For low-value shipments, understanding Section 321 de minimis provisions (shipments valued at $800 or under) can help importers and e-commerce businesses reduce duty exposure on qualifying entries.
If your business is subject to a CBP Focused Assessment or you are considering a Prior Disclosure to address past compliance issues, working with a licensed customs broker or trade attorney is advisable. William Leon can be reached directly at 305-599-0066 to discuss your import needs and determine how to best support your customs compliance goals in the Miami trade zone.
