Edge Cases: FTZ, Warehouse, In-Bond, TIB, and Informal Entries

Informational only - not legal advice.

The mistake to avoid

The dangerous shortcut is: "I have a shipment date and a duty invoice, so I can analyze the refund."

For ordinary consumption entries, that may be enough to start. For edge cases, it often is not. You may need to know whether the goods were:

• admitted into an FTZ before entry for consumption,
• entered into a bonded warehouse and later withdrawn,
• moved in-bond to another port or facility,
• entered temporarily under bond, or
• cleared as an informal or express entry with a thinner record set.

These facts can change which date matters, which duty lines matter, and which party controls the records.

Fast triage table

1) Foreign-trade zones (FTZ)

FTZs are secure areas under CBP supervision that are generally considered outside CBP territory for entry purposes. CBP's FTZ overview explains that ordinary formal entry procedures and duty payment generally are not required until foreign merchandise enters CBP territory for domestic consumption. (CBP - Foreign-Trade Zones overview)

For refund analysis, the key questions are:

• Was the relevant entry a Type 06 FTZ consumption entry?
• Was the merchandise in privileged foreign status?
• What date does the ACE duty-rate-date hierarchy use?
• What Chapter 99 lines and duty amounts appear on the entry summary?
• What is the liquidation status/date?

The privileged-foreign-status issue matters because 19 CFR 146.41 provides that privileged foreign status is requested on Customs Form 214 and remains binding, and 19 CFR 146.65 addresses classification, valuation, and liquidation for FTZ merchandise. CBP's IEEPA FAQ also calls out Type 06 FTZ privileged-foreign-status handling in its duty-rate-date discussion. (19 CFR 146.41, 19 CFR 146.65, CBP IEEPA FAQ)

Practical ask: "Please provide the Type 06 FTZ consumption entry summary, any continuation sheets, the ACE line-level export, and any FTZ status/admission records needed to confirm privileged foreign status and duty-rate date."

2) Bonded warehouse and warehouse withdrawals

A warehouse entry is not the same as a warehouse withdrawal.

CBP regulations define "entered for warehouse" separately from "entered for consumption." Warehouse withdrawals for consumption are filed on CBP Form 7501 or electronic equivalent, and estimated duties are deposited on the merchandise being withdrawn. (19 CFR 141.0a, 19 CFR 144.38)

For tariff review, focus on the withdrawal record:

• 21 / 22 tells you there was warehouse/rewarehouse treatment.
• 31, 32, 34, or 38 usually tells you merchandise was withdrawn from warehouse.
• The withdrawal record is often the document with the duty assessment you need to analyze.

Practical ask: "Please provide the warehouse withdrawal entry summary, the related warehouse entry number, line-level HTS/Chapter 99 duty detail, and liquidation status for the withdrawal."

3) In-bond movements

An in-bond record is usually a movement/disposition record, not the final answer for duty refund analysis.

19 CFR 18.1 describes the in-bond application and general rules for transporting merchandise in-bond. It also contemplates that, after reaching the destination port, in-bond merchandise may be divided with a portion entered for consumption or warehouse and the remainder moved under a new in-bond application. (19 CFR 18.1)

For refund work, ask:

• Did the in-bond move end in consumption entry, warehouse entry, FTZ admission, export, or another in-bond move?
• What is the final entry number tied to the duty assessment?
• Who was the IOR/filer on the final entry?

Practical ask: "Please provide the in-bond number, disposition, destination port, and the follow-on entry number or FTZ/warehouse/export record that closed out the movement."

4) Temporary Importation under Bond (TIB)

TIB entries are their own category. CBP regulations define "entered temporarily under bond" separately from consumption and warehouse entries, and 19 CFR 142.11 identifies formally entered TIB merchandise as using CBP Form 7501 or an electronic equivalent unless another format applies. (19 CFR 141.0a, 19 CFR 142.11)

Do not treat a Type 23 TIB as a normal consumption entry without confirming what happened later:

• Was the merchandise exported or destroyed on time?
• Was the TIB extended?
• Was there a breach or liquidation-damages issue?
• Was any part converted into an ordinary consumption entry?

Practical ask: "Please provide the Type 23 entry summary, TIB bond records, extension/closure records, proof of export/destruction, and any related consumption-entry records."

5) Informal and express entries

Informal entries can still matter. They may not look like a full formal-entry packet, and a carrier duty/tax invoice may be the first record you see, but that does not mean there is no entry-level data.

19 CFR Part 143 governs special entry procedures, including informal entries. It provides that informal entries may be made on specified forms, CBP Form 7501/electronic equivalent, or in some cases a commercial invoice with a declaration, depending on the merchandise and procedure. (19 CFR Part 143, 19 CFR 143.23)

For small-parcel and express flows, ask for:

• entry number or shipment-to-entry-number mapping,
• IOR confirmation,
• duty/tax invoice,
• carrier customs packet,
• broker export or entry-detail report,
• HTS/Chapter 99 detail if duty was assessed.

What to upload

Upload the cleanest entry records you have, but do not wait for perfection:

• Form 7501 PDFs and continuation sheets
• ACE Entry Summary exports
• ACE Account Revenue or liquidation exports
• broker entry-detail spreadsheets
• warehouse entry and withdrawal records
• FTZ admission/status documents
• in-bond records and final disposition records
• TIB bond and closure records
• carrier duty/tax invoices and customs packets

If the edge-case record is incomplete, upload it anyway. It often contains the entry number, filer, port, date, or reference needed to request the final record.
