Under 19 CFR 146.63(c), a zone operator using weekly entry files CBP Form 3461, or its electronic equivalent in ACE as an entry type 06, before the week begins, estimating the merchandise that will be removed from the zone for consumption that week. After the week ends, the operator has 10 working days to file the entry summary, CBP Form 7501, covering what actually left. If actual removals will exceed the estimate, a supplemental 3461 covering the extra units has to be filed before those goods leave the zone. Removing more than you estimated, without that supplemental filing, is a compliance violation on its own, whatever the duty turns out to be. The procedure exists to cut filing volume for manufacturers moving goods out of a zone daily. It trades fewer filings for tighter discipline about one number: the estimate.
The estimate is filed before the goods move
That ordering is the part new zone operators miss. A normal entry describes goods that exist and are presented. A weekly entry estimate describes goods that will be produced or picked during a future week, which means production planning and customs filing sit in the same meeting. If the plant runs an extra shift on Thursday, the entry team needs to know before the trucks load, not in the Friday reconciliation.
Build the estimate with headroom that is honest. An estimate padded far above any plausible week creates its own questions, and an estimate set at the planned number with no buffer breaks the first time a customer pulls an order forward. Most operators land on planned removals plus a realistic surge margin, documented, so the number can be explained if CBP asks how it was built.

The 10 working day summary is where the money settles
The estimate releases goods. The entry summary is the definitive record for duty assessment, and it replaces the estimate with actual quantities and values. Missing the 10 working day window after the zone week ends can trigger a demand for liquidated damages, which for a continuous bond equals the amount that would have been required under a single entry bond. That is real money for a clerical miss.
Some goods never get weekly entry treatment at all. FDA regulated categories including human and animal drugs, tobacco products, most medical devices, and licensed biological products are excluded or restricted, and a negative FDA assessment can push withdrawals back to standard entry treatment. Know your exclusions before you design the filing calendar around a procedure your product cannot use.
Run the week like a reconciliation, not a filing
The operators who stay out of trouble reconcile daily. Removals against estimate, every day, with a named person who can file the supplemental 3461 the moment the week runs hot. The failure mode is never the form. It is the warehouse shipping a pull-forward order on Friday afternoon while the customs file still shows the estimate from Monday.
Frequently asked questions
What form starts an FTZ weekly entry?
CBP Form 3461, filed electronically in ACE as entry type 06, acts as the estimate of merchandise to be removed from the zone during the coming week. The entry summary on Form 7501 follows after the week closes.
What happens if removals exceed the weekly estimate?
A supplemental Form 3461 covering the additional units must be filed before the extra goods leave the zone. Removing merchandise beyond the estimated quantity without a supplemental filing is a compliance violation.
How long do you have to file the FTZ entry summary?
The final entry summary covering actual quantities and values is due within 10 working days after the zone week ends. Missing that window can lead to a demand for liquidated damages.
Which products are excluded from weekly entry?
Several FDA regulated categories are excluded or restricted, including human and animal drugs, tobacco products, most medical devices, and licensed biological products. Operators should confirm eligibility for their specific goods before relying on the procedure.
