Textbook chapter 1
Make a warehouse entry and start the correct clock
Answer first
Determine whether merchandise is eligible for warehouse entry, identify the entry filing route, and calculate the warehousing period from the legally controlling date. Dutiable merchandise may generally be entered for warehousing, but perishable merchandise and explosive substances other than firecrackers are excluded; dangerous or highly flammable merchandise requires the warehouse insurer's written consent. Entry documentation required by §142.3 is filed at entry. A timely Form 7501 or electronic equivalent can serve as both entry and entry summary. The warehousing period runs from the date of importation, not the date of warehouse entry, and is generally capped at five years, subject under current §144.5 to a discretionary longer period on proper request and good cause. Current law was reviewed on 2026-08-18 against the eCFR text current through 2026-08-14. For the October 2026 CBLE, answer from the exam-designated 2025 CFR edition when its wording or numbering differs from live law.
Rule breakdown
Controlling rule for Make a warehouse entry and start the correct clock
19 CFR 144.1; 144.5; 144.11 ↗The result must be derived from the cited legal elements rather than from a label, commercial expectation, or memorized shortcut. Dutiable merchandise may generally be entered for warehousing, but perishable merchandise and explosive substances other than firecrackers are excluded; dangerous or highly flammable merchandise requires the warehouse insurer's written consent. Entry documentation required by §142.3 is filed at entry. A timely Form 7501 or electronic equivalent can serve as both entry and entry summary.

Apply every stated condition to the documented facts and stop if an essential condition cannot be proved.
Evidence route for Make a warehouse entry and start the correct clock
19 CFR 144.1; 144.5; 144.11; 19 CFR 19.6(a); 19 CFR Part 144 (2025 edition); 19 U.S.C. 1557(a) ↗Use the official source in the order required by the issue and record both the rule and the fact that satisfies it. The assigned lookup is: Find the excluded merchandise classes in §144.1, then locate the event that starts the five-year warehousing period in §144.5. Follow this source route: Read §144.1(a), skip to §144.5, and contrast 'date of importation' with the filing date discussed in §144.11.. A technically accepted filing or a completed reading is not itself proof that the legal outcome is correct.
Decision path
- 1
Set the gate for Make a warehouse entry and start the correct clock
Determine whether merchandise is eligible for warehouse entry, identify the entry filing route, and calculate the warehousing period from the legally controlling date. Identify the legally significant party, merchandise, event, date, value, status, and document before selecting a rule or performing a calculation.
- 2
Verify 19 CFR 144.1; 144.5; 144.11
Open 19 CFR 144.1; 144.5; 144.11, complete the chapter lookup task, and preserve the exact subsection, table, form, or agency guide used. Follow Read §144.1(a), skip to §144.5, and contrast 'date of importation' with the filing date discussed in §144.11. rather than jumping directly to a remembered result.
- 3
Test the boundary of Make a warehouse entry and start the correct clock
Apply each controlling element to the documented facts, calculate only after eligibility is established, and compare the result with the worked example conclusion: The importation date controls, so the ordinary five-year limit is measured from May 1, 2026. Record any unresolved fact instead of converting uncertainty into a pass or mastery claim.
Worked example
Scenario: Dutiable machinery is imported on May 1, 2026, and entered for warehouse on June 15, 2026. No discretionary extension is granted. What date controls the ordinary five-year limit?
- 1.Confirm that the machinery is dutiable and no stated §144.1 exclusion applies.
- 2.Separate the importation date from the later warehouse-entry date.
- 3.Apply §144.5 from May 1, 2026, rather than June 15, 2026.
- 4.Set the ordinary outer limit at May 1, 2031, absent an approved longer period.
- 5.Boundary check: change one decisive fact identified by “Find the excluded merchandise classes in §144.1, then locate the event that starts the five-year warehousing period in §144.5.” and explain whether the result changes under 19 CFR 144.1; 144.5; 144.11; 19 CFR 19.6(a); 19 CFR Part 144 (2025 edition); 19 U.S.C. 1557(a).
Conclusion: The importation date controls, so the ordinary five-year limit is measured from May 1, 2026.
Common traps and corrections
× Starting the five-year clock on the warehouse-entry or physical-deposit date.
✓ The shortcut “Starting the five-year clock on the warehouse-entry or physical-deposit date.” skips a controlling distinction in Make a warehouse entry and start the correct clock. Return to 19 CFR 144.1; 144.5; 144.11, follow Read §144.1(a), skip to §144.5, and contrast 'date of importation' with the filing date discussed in §144.11., and test the decisive fact against this boundary: Dutiable merchandise may generally be entered for warehousing, but perishable merchandise and explosive substances other than firecrackers are excluded; dangerous or highly flammable merchandise requires the warehouse insurer's written consent. Entry documentation required by §142.3 is filed at entry. A timely Form 7501 or electronic equivalent can serve as both entry and entry summary. The warehousing period runs from the date of importation, not the date of warehouse entry, and is generally capped at five years, subject under current §144.5 to a discretionary longer period on proper request and good cause.
