To operate a customs bonded warehouse, you file a written bonded warehouse application with CBP through the port director at the port nearest the facility, describing the premises, its location, and the class of warehouse you want to run. Once the port director approves the application, you execute a customs bond on CBP Form 301, and the warehouse is authorized to operate under the class and conditions CBP set.
The application itself is not long. What takes time is getting the pieces right before you file: choosing the correct class, preparing premises that will pass a security review, estimating duties honestly, and having a surety ready to write the bond the port director will require.
Choose the Warehouse Class Before You File
CBP recognizes eleven classes of bonded warehouses, and the application must specify which one you want. The class controls what you can store and what operations you can perform on the premises, so choosing wrong means either denial or an approval that doesn’t cover what you actually need to do.
The classes most applicants seek:
- Class 2, private storage, reserved for merchandise belonging to or consigned to the warehouse proprietor. Nobody else’s goods go in.
- Class 3, public storage, open to any importer’s merchandise. This is the class for offering warehousing as a service to other businesses.
- Class 8, manipulation, which allows cleaning, sorting, repacking, and similar conditioning of imported goods, but not manufacturing.
Other classes cover government-owned warehouses (Class 1), bonded yards and sheds (Class 4), bonded bins (Class 5), smelting and refining facilities (Classes 6 and 7), duty-free stores (Class 9), and several specialized operations. Pin this down first. Everything else in the application flows from it.
Who Can Apply and What CBP Will Check
The owner or lessee of the facility applies to become the warehouse proprietor. The application must describe the premises in detail, give the location, and state the desired warehouse class. For a private (Class 2) warehouse, you also need to describe the type of merchandise you plan to store and estimate the maximum duties and taxes that would be owed on all goods held in the facility at any one time.
The port director has discretion to look into you. Under 19 CFR 19.2, the port director may order an inquiry into the applicant’s qualifications, character, and experience, including personal history, financial and business data, and credit references. The port director may also request names, addresses, and fingerprints for all company officers, principals, and anyone with access to recordkeeping information. These inquiries are discretionary rather than automatic, but expect them and have the information ready.
Premises and Physical Security
CBP scrutinizes the facility because it holds goods under customs custody. The building must be constructed so that no one can enter without using enough force to leave obvious signs of a break-in. Doors, windows, and other access points must be secured accordingly.
If bonded and non-bonded merchandise will share the same building, the port director will require effective separation between the two areas. That might be a wall, a fence, or in some cases a painted line, depending on the circumstances. Inlets and outlets to bonded tanks must be secured with locks or in-bond seals. Beyond physical barriers, your written procedures must be adequate to ensure the security of all merchandise under customs custody.
Merchandise must be stored safely to minimize damage, avoid hazards, and comply with any local, state, or federal rules for the specific goods involved. Doors and entrances must stay unblocked so CBP officers and warehouse staff can access the facility at all times. Include floor plans and diagrams with your application showing the layout, bonded areas, and security features. The port director can order an on-site inspection by a CBP officer to verify that what’s actually built matches what you described.
What Goes Into the Written Application
You submit the application to the port director at the CBP port nearest the warehouse location. It is a written request describing the premises, its location, and the class of warehouse you want to establish. Along with the request itself, plan to include:
- Premises documentation: floor plans, location maps, and diagrams showing the facility layout, bonded and non-bonded areas, and security measures.
- Business entity information: your Employer Identification Number and documentation of your legal business structure.
- Merchandise and duty estimates: for private warehouses, the general character of goods to be stored and an estimate of the maximum duties and taxes owed on all stored merchandise at any one time.
The port director uses your duty estimate to help set the bond amount, so lowballing the number creates trouble later. Overestimating means a higher bond premium. Underestimating can delay approval or force you to scramble to increase your bond after the fact.
The Customs Bond You’ll Execute on Approval
Every bonded warehouse except Class 1 must be backed by a customs bond executed on CBP Form 301. The bond is a financial guarantee that the proprietor will comply with all customs laws and regulations, pay any duties, taxes, and charges that come due, and cover the government’s risk on merchandise in the facility.
Timing matters here. The bond is executed after the application is approved, not before. Under 19 CFR 19.2, the bond is required “on approval of the application.” Line up a Treasury-licensed surety company early so you’re ready to move once the port director issues approval, but the formal execution happens at that point rather than at filing.
Bond Amount
The minimum bond amount is $25,000 per building or bonded area. The port director sets the actual amount based on the purpose of the bond and the estimated duties and taxes at risk. Larger operations with significant duty exposure will see bonds well above the minimum. The bond must be issued by a Treasury-licensed surety authorized to write federal bonds.
What the Bond Covers
The bond conditions under 19 CFR 113.63 are broad. As proprietor, you and your surety agree to properly receive, store, and account for all bonded merchandise; maintain required records; comply with CBP regulations on handling and disposition of goods; reimburse the government for the cost of any CBP officers, locks, seals, or other expenses tied to the bonded operation; and pay any charges arising from your custodial activities. Default triggers joint liability for liquidated damages equal to the value of the merchandise involved, with restricted or prohibited goods and alcoholic beverages tripling that figure.
How CBP Reviews the Application
Once CBP receives the application, the port director evaluates the applicant’s fitness, the facility’s security, and the adequacy of the proposed operation. The port director may order an on-site inquiry by a CBP officer to inspect the premises and confirm the security measures match what you described. Physical security must meet the port director’s approval before the warehouse can be bonded.
There is no fixed timeline. Review periods vary with the application’s complexity, the port’s workload, and whether the port director orders additional inquiries. Incomplete applications and facilities that need modifications to meet security standards will take longer. On approval, the port director authorizes the warehouse to operate under the specified class and conditions, and the customs bond is formally executed.
What You’re Committing to After Approval
Approval is the start of the obligation, not the end. As proprietor, you supervise all transportation, receipts, deliveries, sampling, recordkeeping, repacking, manipulation, destruction, security, storage conditions, and safety in the warehouse. The standard is the level of supervision a prudent manager of a storage facility would exercise. You must permit CBP officers access to the warehouse and present merchandise within a reasonable time after any request.
Your inventory system must account for every piece of merchandise from receipt through withdrawal, with records detailed enough for CBP to determine compliance. A written procedures manual in English must be kept at the warehouse describing your inventory control and recordkeeping systems, and any change to that system requires a new certification to the port director. Records concerning bonded merchandise must be retained for five years after the date of the final withdrawal under each entry.
Applicants sometimes underestimate this side of the job. The application asks CBP to trust you as a custodian of goods the government has a financial stake in. Build the premises, the procedures, and the recordkeeping to that standard before you file, and the review moves faster and cleaner.
