# Bonded warehouse software that keeps every lot tied to its entry and its bond clock

> A bonded warehouse is a facility where imported goods are stored under bond without payment of duty until they are withdrawn. US rules in 19 CFR Part 19 define classes 1 through 11, merchandise may generally remain up to 5 years from the date of importation, and the proprietor files an annual reconciliation within 45 days of the end of the business year. Neurobird ties each lot to its entry, duty status and remaining bond time.

## What Neurobird Bonded Warehouse does

- Hold every lot against its entry number, class and duty status rather than against a location alone
- Run the five year bond clock per lot and warn before goods go to general order
- Record every withdrawal, manipulation and transfer as a permitted event with the paperwork attached
- Produce the annual reconciliation from the same record the floor is already updating

## How it works

1. **Receive against the entry** Every lot is recorded to its warehouse entry, class and duty status at the door, not reconstructed later from paperwork.
2. **Watch the bond clock** Days under bond run per lot. Warnings arrive with time to act, well before the 5 year limit or a general order deadline.
3. **Log permitted events** Withdrawals, manipulations, transfers and destructions are recorded as events with documents attached, which is exactly what the reconciliation needs.

## From the source material

> A warehouse of class 4 or 5 may be bonded exclusively for the storage of goods imported by the proprietor thereof, in which case it shall be known as a private bonded warehouse.

- **19 CFR 19** The federal part governing customs bonded warehouses, including the 11 classes, the proprietor duties and the inventory control and recordkeeping requirement. (source: Electronic Code of Federal Regulations, 19 CFR Part 19, https://www.ecfr.gov/current/title-19/chapter-I/part-19)
- **19 CFR 113** Customs bond rules, which set the financial instrument standing behind every bonded facility and every entry in it. (source: Electronic Code of Federal Regulations, 19 CFR Part 113, https://www.ecfr.gov/current/title-19/chapter-I/part-113)
- **19 CFR 144** Warehouse and rewarehouse entries and withdrawals, the rules that define what a legitimate movement out of bond looks like. (source: Electronic Code of Federal Regulations, 19 CFR Part 144, https://www.ecfr.gov/current/title-19/chapter-I/part-144)
- **19 CFR 146** Foreign trade zone rules, the alternative duty deferral regime bonded operators are usually asked to compare against. (source: Electronic Code of Federal Regulations, 19 CFR Part 146, https://www.ecfr.gov/current/title-19/chapter-I/part-146)

## Questions

### What is a customs bonded warehouse?

A customs bonded warehouse is a facility where imported goods are stored under bond without payment of duty until they are withdrawn. US regulations under 19 CFR Part 19 define classes 1 through 11 of bonded warehouse, and merchandise may generally remain in a bonded warehouse for up to 5 years from the date of importation.

### What is the annual reconciliation?

A report the proprietor files with the port director covering the warehouse business year, due within 45 days of the end of that year. It reconciles what was received, what was withdrawn and what remains, which is only easy if the inventory record tracked entries all along.

### What happens if goods pass the 5 year limit?

They become subject to sale or other disposition. That is a duty and revenue event, not a housekeeping one, so the practical requirement is a warning long before day 1,825, not a discovery afterwards.

### Does this replace our WMS?

No. If you run a warehouse management system it keeps doing locations and picking. The entry linkage, duty status, bond clock, permitted events and the reconciliation live here.
