MRB International LLC

MRB International LLC is a North Carolina-based customs brokerage firm licensed by U.S. Customs and Border Protection, operating under filer code N6D. The company was formally organized as a domestic LLC under North Carolina state law and serves importers who require professional representation before CBP for commercial and regulated shipments entering the United States.

For importers unfamiliar with U.S. import requirements, the customs clearance process involves several critical steps — from proper HTS code classification and valuation to the timely submission of entry documentation through the CBP ACE portal. MRB International assists clients in preparing accurate customs entries across multiple CBP entry types, helping ensure that duties are assessed correctly and that shipments are not delayed at the border due to documentation errors or classification disputes.

One area of focus for any serious importer is maintaining a valid customs bond. CBP requires that importers either hold a single-entry bond or a continuous customs bond to guarantee payment of duties, taxes, and fees. MRB International can advise clients on customs bond requirements appropriate to their import volume and commodity type, helping them stay compliant without over-purchasing coverage.

Importer Security Filing — commonly referred to as ISF or the 10+2 rule — is another area where professional brokerage support adds real value. ISF filings must be submitted to CBP at least 24 hours before cargo is loaded at the foreign port, and late or inaccurate filings can result in significant penalties. Working with a licensed broker like MRB International helps importers meet these deadlines accurately.

Raleigh, NC sits within the Research Triangle, a region known for advanced manufacturing, life sciences, technology, and textile-related industries. Importers in this corridor frequently source goods from overseas markets and may benefit from guidance on HTS code classification for categories like electronics, machinery, consumer goods, or textiles and apparel. MRB International is equipped to assist with the USITC tariff database lookups and HTS code classification decisions that affect duty rates and admissibility.

Additionally, importers who have overpaid duties in prior periods may be eligible to recover those funds through a duty drawback program. MRB International can discuss whether duty drawback claims are appropriate for a given importer's situation. For businesses receiving lower-value shipments, questions around the Section 321 de minimis threshold are also common — understanding how CBP entry types and de minimis rules interact can meaningfully affect cost and compliance strategy.
