Bonded Warehouse
Warehouse authorized to store imported goods under customs bond before duty payment.
Definition
Bonded warehouses provide secure storage for goods under customs control, deferring duties until release for domestic use or export.
Overview of Bonded Warehouse
A bonded warehouse is a secure storage facility that has been officially licensed and authorized by the customs authority — in the United States, Customs and Border Protection — to store imported goods that have not yet cleared customs or had applicable duties and taxes paid. The warehouse operator posts a surety bond with the customs authority that covers the potential duty liability on all goods in their custody, effectively guaranteeing that goods will either be properly entered into commerce with duties paid, re-exported without duty payment, or accounted for if lost or destroyed. Bonded warehouses serve as a critical bridge in the import supply chain, providing importers the flexibility to store goods beyond the port free-time period without paying duties immediately upon arrival. Bonded warehouses are classified into different types based on their permitted activities: Class 2 and 3 warehouses store general merchandise and dutiable goods awaiting entry. Class 6 warehouses allow manipulation — repackaging, sorting, and relabeling — of imported goods. Class 7 smelting and refining warehouses process ores and metals. Class 9 bonded manufacturing warehouses produce finished goods from imported components, paying duty only on the finished product. From an operational perspective, a bonded warehouse must maintain strict physical security, detailed inventory records of all bonded goods by entry, and separation of bonded inventory from any non-bonded goods stored in the same facility. CBP conducts periodic audits of bonded warehouse records and physical inventory. WareMatch helps importers identify bonded warehouse operators with current CBP licensing, experienced customs compliance staff, and the operational infrastructure needed to manage bonded inventory alongside standard warehousing services. Through the WareMatch marketplace, businesses can find bonded warehouse operators at strategic import gateway locations — major port cities and inland freight hubs — who can support their import supply chain requirements.

FAQs
Q: How does a warehouse obtain bonded warehouse authorization?
A: To obtain bonded warehouse status, the warehouse operator submits an application to the CBP Center of Excellence and Expertise for the relevant port, provides facility information (location, security systems, record-keeping practices), passes a CBP inspection of the facility, and posts a surety bond in an amount determined by CBP based on the estimated duty liability of goods expected to be stored. The bond amount is typically set based on maximum expected inventory value and applicable duty rates. Once approved, the operator receives a bonded warehouse license that must be renewed and maintained through ongoing compliance.
Q: What records must a bonded warehouse maintain?
A: A bonded warehouse must maintain detailed records for every entry of goods into bond — the entry number, quantity, description, and value of goods received — and every withdrawal, manipulation, or re-export. Records must track the current quantity of each bonded entry still in storage and must be reconcilable with CBP entry records. The operator must retain these records for at least five years. CBP may conduct compliance audits that compare warehouse records to CBP entry data, and discrepancies can result in penalties or bond demands.
Q: Can a regular commercial warehouse add bonded warehouse capability?
A: Yes, existing commercial warehouses can apply for bonded warehouse authorization as an additional service offering, provided they meet CBP facility security requirements — including perimeter security, access controls, CCTV monitoring, and ability to segregate bonded from non-bonded inventory — and can demonstrate the record-keeping systems necessary for compliance. Many 3PL providers add bonded warehouse capability specifically to serve importer clients who need the flexibility of in-bond storage alongside standard warehousing services.
Q: What happens if a bonded warehouse operator goes out of business?
A: If a bonded warehouse operator ceases operations, CBP must be notified immediately and all bonded goods in the facility must be accounted for. The goods must either be entered for consumption (with duties paid) or re-exported before the facility closes. If goods cannot be accounted for, the surety bond is called upon to pay the applicable duties. Importers should maintain their own records of all bonded entries stored at a third-party bonded warehouse and monitor the operator financial health to ensure continuity of bonded storage services.
