MAINTENANCE
  Owner | Change trigger last fired | Next scheduled review

Drafting notes.

Rank by duty spend and build in that order. In most import programs the top twenty percent of SKUs carry eighty percent of the duty, and a partially built database covering the top quintile is worth far more than a complete one that took two years.

The "Change trigger last fired" field is what makes the control auditable. A SKU whose specification changed in 2023 and whose trigger last fired in 2019 is the exposure.

Link to the memoranda rather than summarizing them. The database is an index; the analysis lives in the files.

2. Classification worksheet

CLASSIFICATION WORKSHEET
SKU: __________  Date: __________  Prepared by: __________

1. THE ARTICLE
   Commercial description:
   Technical description (composition, dimensions, function,
   how it works, how it is used, how it is sold):
   Condition as imported (assembled? packaged? complete?):
   Materials and percentages by weight and by value:
   [Attach specification, drawings, and photographs.]

2. GRI 1 — HEADINGS AND NOTES
   Candidate headings considered:
   Terms of each heading:
   Section notes reviewed:  Chapter notes reviewed:
   Any note that excludes or directs:
   CONCLUSION UNDER GRI 1: ____________
   [ ] Resolved at GRI 1 — go to GRI 6
   [ ] Not resolved — continue

3. GRI 2
   (a) Incomplete/unfinished with essential character of the
       finished article?  Unassembled/disassembled?
   (b) Mixture or combination?

4. GRI 3 (only if two or more headings apply)
   (a) Most specific description:
   (b) Essential character — which material or component gives
       the article its essential character, and why (bulk,
       quantity, weight, value, role in relation to the use):
   (c) Last in numerical order:

8. TARIFF PROGRAM CONSEQUENCES
   Section 301 / 232 / AD-CVD applicability at this subheading:

9. REVIEW
   Reviewed by: __________  Date: __________

Drafting notes.

Section 2 is where the work is. Most misclassifications come from skipping to essential character analysis under GRI 3(b) without exhausting GRI 1 — the terms of the headings and the section and chapter notes resolve the large majority of classifications, and the notes frequently contain an exclusion that ends the analysis.

Section 6's "similar articles (list and distinguish)" is what a CBP officer will want to see. Rulings on similar articles that reach a different result must be addressed, not ignored.

Section 7's confidence rating drives the ruling decision. Pair it with a company policy: any "Low" confidence with annual duty above a threshold goes to a ruling request.

3. Binding ruling request

[Date]
U.S. Customs and Border Protection
Regulations and Rulings, Office of Trade
[Address / eRulings submission]

Re: Request for a Binding Ruling under 19 C.F.R. Part 177 —
    Tariff Classification [and/or Country of Origin] of
    [product]

Dear Sir or Madam:

On behalf of [Importer], we request a binding ruling on the
[tariff classification / country of origin] of [product].

1. REQUESTER
   [Name, address, IRS number. State whether the requester is
   the importer, and identify any related party.]

2. TRANSACTION STATUS
   [State whether the merchandise has been imported, is the
   subject of a pending entry, or is prospective. Confirm that
   to the best of our knowledge the issue is not the subject of
   a current CBP transaction, protest, or litigation, and
   identify any prior ruling requested on the same or a
   substantially similar article.]

3. THE MERCHANDISE
   [Complete description: composition by material and
   percentage, dimensions, weight, function, principal use,
   manner of packaging and sale. Attach specifications,
   drawings, photographs, and a sample if practicable.]

4. MANUFACTURING PROCESS AND ORIGIN
   [Where each material originates; every operation performed
   and where; the sequence; the equipment and skill involved;
   the value added at each stage.]

5. PROPOSED CLASSIFICATION [AND ORIGIN]
   We believe the merchandise is classified under HTSUS
   __________ [and is a product of __________].

6. ANALYSIS
   GRI 1: [terms of the headings; section and chapter notes]
   [GRI 2/3/6 as applicable]
   Explanatory Notes: [cite and apply]
   CBP rulings: [cite supporting rulings; ADDRESS AND
   DISTINGUISH contrary rulings]
   Court decisions: [cite]
   [For origin: the substantial transformation analysis —
   whether the operations produce a new and different article
   with a distinct name, character, or use.]

7. CONCLUSION

We would be pleased to provide any additional information.

Respectfully submitted,

Drafting notes.

Section 6's instruction to address contrary rulings is the difference between a good request and a bad one. CBP will find them. A request that distinguishes them is credible; one that ignores them looks like advocacy and invites a longer review or an adverse result.

Section 3 must be complete. A ruling binds CBP only as to the merchandise described. An incomplete description produces a ruling that does not cover the goods you import.

Section 2's disclosures are required and omitting them can void the ruling.

Timing. Electronic requests are generally processed in 30 to 90 days. Do not import in volume on a low-confidence classification while waiting; consider the timing when planning a launch.

4. Origin determination memorandum

COUNTRY OF ORIGIN DETERMINATION
Product: __________  Date: __________  Prepared by: ________

1. THE PRODUCT AS IMPORTED
   [Description, function, use.]

2. MATERIALS AND INPUTS
   | Input | Description | Country of origin | Cost | % of
     total material cost |

3. OPERATIONS
   | # | Operation | Country | Description | Equipment | Skill
     required | Value added | % of total |

4. SUBSTANTIAL TRANSFORMATION ANALYSIS
   (a) NAME — does the article have a different name after the
       operations in [country]?
   (b) CHARACTER — is the character of the article changed?
       [Physical, chemical, functional.]
   (c) USE — is the use changed, or was the article's use
       predetermined by the inputs?
   (d) The essence of the analysis: which operation gives the
       article its identity as the article it is?

5. SUPPORTING AUTHORITY
   [CBP rulings on similar articles and similar operations —
   cite, describe, and explain why they support or are
   distinguishable. Court decisions.]

6. PREFERENTIAL ORIGIN (separate analysis)
   Agreement: __________
   Product-specific rule: [tariff shift / RVC / both]
   Analysis:
   Conclusion: [originating / not originating]

7. CONCLUSIONS
   Non-preferential country of origin: __________
   Preferential origin: __________
   NOTE ANY DIFFERENCE and its consequences for Section 301,
   marking, and duty rate.

8. TARIFF CONSEQUENCE
   Annual duty at each candidate origin: __________
   Difference: __________
   Ruling recommended? [ ] Yes  [ ] No

9. MARKING
   Method, location, and compliance confirmation.

Drafting notes.

Section 7's instruction to note any difference between preferential and non-preferential origin addresses the single most common origin error: assuming that USMCA-originating means not a product of China. It does not, and the Section 301 consequence of the confusion is large.

Section 3's value-added column is what makes the analysis persuasive. Substantial transformation is qualitative, but CBP and the courts look at value added as evidence of the significance of the operations.

Section 8 forces the ruling decision onto the memorandum, where it belongs.

5. Assist identification form

Embed this in the purchase requisition and the supplier onboarding form.

CUSTOMS — SUPPLIER PROVISION DISCLOSURE
(Complete for every foreign supplier engagement)

Requisition/PO: __________  Supplier: __________
Country of production: __________

Are we providing, or will we provide, ANY of the following to
this supplier free of charge or at less than full cost?

[ ] Tooling, molds, dies, jigs, fixtures, or patterns
[ ] Machinery or equipment
[ ] Components, parts, or subassemblies
[ ] Raw materials
[ ] Consumables used in production
[ ] Engineering or development work
[ ] Design work, drawings, or plans
[ ] Artwork or sketches
[ ] Software used in production
[ ] Technical assistance or on-site engineering support
[ ] Testing or quality equipment
[ ] NONE OF THE ABOVE

For each item checked:
  Description: ____________________________________
  Our cost to acquire or produce it: $______________
  WHERE was it produced or the work performed? ____________
    (Design and engineering are dutiable assists ONLY if
     performed OUTSIDE the United States. Physical items are
     assists wherever produced.)
  Expected production volume it will support: ____________
  Transportation cost to the supplier: $____________

Submitted by: __________  Date: __________
Routed to Trade Compliance: [ ] Yes   Date: __________

Drafting notes.

The location question for design and engineering is the one people get wrong in both directions. U.S.-developed engineering is not a dutiable assist; foreign-developed engineering is. Companies both over-declare and under-declare on this point.

"Expected production volume" is what enables apportionment. Collect it at the time; reconstructing it later is guesswork.

Put this in the requisition form, not in a policy document. Procurement staff complete forms; they do not read customs policies.

6. First sale documentation checklist

FIRST SALE VALUATION — DOCUMENTATION
Product: __________  Middleman: __________
Manufacturer: __________

ELEMENT 1 — CLEARLY DESTINED FOR THE UNITED STATES
[ ] Purchase order from importer to middleman, predating or
    contemporaneous with the manufacturer's production
[ ] Middleman's purchase order to the manufacturer referencing
    the U.S. order or U.S. specifications
[ ] U.S.-specific markings, labels, packaging, or language
[ ] U.S.-specific regulatory compliance (FCC, UL, FDA labeling)
[ ] Production records showing the goods were made to the U.S.
    order
[ ] Shipping documents showing direct shipment or a routing
    consistent with U.S. destination

ELEMENT 2 — BONA FIDE SALE
[ ] Manufacturer's invoice to the middleman
[ ] Evidence of payment by the middleman to the manufacturer
[ ] Terms of sale showing transfer of title and risk of loss
[ ] The middleman's assumption of risk

ELEMENT 3 — ARM'S LENGTH / NO NON-MARKET INFLUENCE
[ ] Relationship between manufacturer and middleman disclosed
[ ] If related: circumstances of sale or test value analysis
[ ] Relationship between middleman and importer disclosed
[ ] If related: same analysis

COMPUTATION
  First sale price: $__________
  Additions (assists, commissions, royalties, proceeds):
    $__________
  Declared value: $__________
  Second sale price (for comparison): $__________
  Annual duty saving: $__________

RETENTION
[ ] All of the above held by the IMPORTER for five years
[ ] Middleman contractually obligated to provide and retain
    records and to cooperate with any CBP inquiry

Drafting notes.

Element 1 is where first sale claims fail. "Clearly destined for the United States" at the time of the first sale requires evidence contemporaneous with that sale, not evidence created afterward.

The middleman's cooperation obligation must be contractual. A middleman who declines to produce its records at audit time defeats the claim, and the importer bears the consequence.

Do not claim first sale until the file is complete. It is a frequent audit target and an incomplete claim is worse than no claim.

7. Supplier trade compliance questionnaire

SUPPLIER TRADE COMPLIANCE QUESTIONNAIRE
Supplier: __________  Date: __________

A. IDENTIFICATION
   Legal name, address, ownership, parent entities
   All production facilities: name, full address, ownership
   Any subcontractor used for any operation: name, address,
     operation performed

B. PRODUCTION
   For each product supplied:
     Materials used, with the country of origin of each
     Every operation performed, and where
     Any operation performed outside your facility
     Value added at your facility

C. ORIGIN
   Your view of the country of origin of each product, and the
   basis
   Any origin ruling or determination you rely on

D. TRACEABILITY (for products with UFLPA-exposed inputs)
   Full supply chain, tier by tier, to the raw material:
     Tier 1: __________  Tier 2: __________
     Tier 3: __________  Tier 4: __________
   For each tier: entity name, address, country, and the
     documentation available
   Any entity in the chain located in, or affiliated with an
     entity located in, the Xinjiang Uyghur Autonomous Region
   Any entity on any restricted or entity list

E. LABOR
   Recruitment practices; use of labor agents or brokers
   Any recruitment fees paid by workers
   Wage and hour records availability
   Any government-sponsored labor transfer program
   Third-party social audits within the past 24 months
     (provide reports)

F. CERTIFICATIONS AND COMMITMENTS
   [ ] The information above is complete and accurate
   [ ] We will notify you within 10 days of any change in
       materials, process, facility, or subcontractor
   [ ] We will provide, on request and within 15 days, all
       documentation supporting origin and traceability
   [ ] We will permit announced and unannounced audits of our
       facilities and those of our suppliers
   [ ] We will not subcontract any operation without written
       consent
   [ ] We will cooperate fully with any CBP inquiry, detention,
       or request for information
   [ ] We will indemnify you for costs arising from any
       detention, exclusion, or penalty attributable to
       inaccurate information provided by us

Authorized signature: __________  Title: __________

Drafting notes.

Section F's notification commitment is the supplier-side change trigger. Without it, the importer learns of a facility change when CBP does.

The indemnity in the last box is worth negotiating hard for. Detention costs — demurrage, storage, re-export, lost sales — are substantial, and they should fall on the party whose information was wrong.

Section D's tier-by-tier request will produce resistance. Persist. A supplier that cannot or will not trace its own inputs is telling you something about your exposure.

8. Broker standing instructions

STANDING INSTRUCTIONS — [Importer] to [Broker]
Effective: __________  Supersedes: __________

1. CLASSIFICATION. Enter each product using the HTSUS
classification set out in the attached Product Schedule. DO NOT
classify any product not on the Schedule. If a shipment
contains a product not on the Schedule, DO NOT FILE — contact
[name] at [contact] for instructions.

2. VALUATION. Declare the value as: [invoice price] PLUS the
assist amount shown on the Product Schedule PLUS [other
additions] LESS [separately identified freight, insurance, and
post-importation services]. Where the Product Schedule
indicates first sale, use the first sale price shown on the
manufacturer's invoice.

3. ORIGIN. Declare the country of origin shown on the Product
Schedule. Do not rely on the supplier's invoice statement of
origin.

4. PREFERENCE CLAIMS. Claim preference only where the Product
Schedule so indicates and a valid certification is on file.

5. TARIFF PROGRAMS. Apply the Section 301 / 232 / AD-CVD
treatment shown on the Product Schedule. If a shipment appears
to fall within an AD/CVD order not shown, DO NOT FILE — contact
[name].

6. ESCALATION. Contact [name] at [contact] before filing if:
   - the product is not on the Product Schedule
   - the invoice description differs from the Schedule
   - the origin differs from the Schedule
   - the value differs by more than [10]% from historical
   - CBP raises any question
   - any document is missing

7. RECORDS. Provide [Importer] with a complete copy of every
entry package within [5] business days of filing, including the
entry summary, invoices, packing lists, bills of lading, and
any correspondence with CBP.

8. NOTICES. Forward any CF 28, CF 29, notice of detention,
notice of extension of liquidation, or other CBP communication
to [name] within [24] hours of receipt.

9. NO SUBSTITUTION. Do not substitute a classification, value,
or origin for any reason without written instruction.

Drafting notes.

Paragraph 1's "DO NOT FILE" instruction is the single most useful line. Brokers faced with an unlisted product will otherwise classify it themselves, and the importer discovers the classification years later.

Paragraph 7's record delivery obligation is what fills the importer's own records repository. Without it, the records exist only at the broker.

Paragraph 8's 24-hour forwarding matters because CF 28 deadlines and protest periods run whether or not the importer has seen the notice.

Review the Product Schedule quarterly and reissue it. Standing instructions that reference a two-year-old schedule are not instructions.

9. Internal entry audit worksheet

ENTRY AUDIT — Quarter __________
Entries selected: __________  Method: [random / risk-based]

For each entry:

ENTRY # __________  Date __________  Value $__________

[ ] Classification matches the Product Schedule
    If not: entered ______  should be ______  Δ duty $______
[ ] Value matches instructions
    Invoice price ______  Assists added ______
    Exclusions properly identified ______
    If not: Δ duty $______
[ ] Origin matches the Product Schedule
    If not: entered ______  should be ______  Δ duty $______
[ ] Preference claim supported by a certification on file
[ ] Section 301 / 232 / AD-CVD treatment correct
[ ] Marking requirement satisfied
[ ] Invoice complete and accurate (19 U.S.C. § 1481)
[ ] Records complete and in the importer's repository
[ ] Liquidation date recorded; protest deadline calendared

SUMMARY
  Entries reviewed: ______
  Errors found: ______  Error rate: ______%
  Net duty impact: $______ [under / over]
  Systemic issues identified: ____________________
  Corrective actions and owners: __________________
  Prior disclosure warranted? [ ] Yes  [ ] No
  Post summary correction / protest opportunities: ________

Drafting notes.

Track the error rate over time. A program whose error rate is falling is working; one that has never measured it does not know.

Look for overpayments as deliberately as underpayments. In most first audits the overpayments are larger, and they are recoverable through post summary correction and protest if the deadlines have not passed.

The "systemic issues" line is the point. A single miscoded entry is a correction; the same error across a product family is a process failure and possibly a disclosure.

10. CF 28 response framework

BEFORE RESPONDING

[ ] Calendar the deadline; request an extension in writing if
    needed (usually granted).
[ ] READ THE QUESTION. What is CBP examining — classification,
    value, origin, a preference claim, an AD/CVD scope
    question? The question tells you what to review.
[ ] Pull the entry file and the underlying records.
[ ] REVIEW THE ENTRIES YOURSELF, UNDER PRIVILEGE, BEFORE
    RESPONDING. If the response will reveal an error:
      - Scope the error across all affected entries and products
      - Quantify the duty consequence
      - Evaluate prior disclosure IMMEDIATELY — the window can
        close
[ ] Determine whether counsel should be engaged.

THE RESPONSE

Re: CBP Form 28, Entry No. __________

1. [Answer each question asked, directly and completely.]
2. [Provide the documents requested.]
3. [Where the answer requires analysis — a classification or
   origin determination — provide the analysis, with the
   supporting rulings.]
4. [Where a ruling supports the position, cite and attach it.]

DO
  - Answer what is asked
  - Provide complete documents
  - Explain the basis for the position, with authority
  - Be accurate

DO NOT
  - Volunteer information about unrelated entries or products
  - Provide analysis that is speculative or incomplete
  - Respond before understanding whether an error exists
  - Miss the deadline

Drafting notes.

The instruction to review before responding is the operative one. A CF 28 response that reveals an error the importer had not investigated forecloses prior disclosure and converts a manageable problem into an enforcement matter.

A CF 28 is not automatically the commencement of a formal investigation, but the window for disclosure can close quickly. Speed matters.

11. Prior disclosure letter

Shell disclosure — file first, to establish the date:

[Date — file the day you decide]
Fines, Penalties and Forfeitures Officer

[Port]

Re: PRIOR DISCLOSURE under 19 U.S.C. § 1592(c)(4)
    [Importer], IRS No. __________

Dear Sir or Madam:

[Importer] hereby makes a prior disclosure under 19 U.S.C.
§ 1592(c)(4) and 19 C.F.R. § 162.74.

1. CLASS OR KIND OF MERCHANDISE
   [Describe the merchandise involved — the product lines and
   HTSUS headings. SCOPE THIS BROADLY ENOUGH to cover every
   product affected by the error.]

2. PORTS AND PERIOD
   Ports of entry: __________
   Approximate period: __________ to __________

3. NATURE OF THE DISCLOSURE
   [Importer] has determined that entries of the above
   merchandise may have contained [material false statements
   regarding classification / value / origin], specifically
   [brief description of the error and how it occurred].

4. CIRCUMSTANCES
   [Importer] discovered this matter on or about [date] in the
   course of [an internal review / an audit / a change in
   personnel]. [Importer] is conducting a review to identify
   all affected entries and to quantify the loss of duties, and
   will supplement this disclosure with full particulars within
   thirty (30) days.

5. NO KNOWLEDGE OF INVESTIGATION
   [Importer] has no knowledge of the commencement of any
   formal investigation of this matter.

6. TENDER
   [Importer] will tender the actual loss of duties upon
   completion of the calculation, or within thirty days of a
   demand by CBP.

Respectfully submitted,

Full disclosure — supplement within thirty days:

SUPPLEMENT TO PRIOR DISCLOSURE dated [date]

1. THE ERROR
   [Precise description: what was declared, what should have
   been declared, and why.]

2. HOW AND WHY IT OCCURRED
   [The process failure. Be candid; CBP evaluates whether the
   disclosure reflects genuine understanding.]

3. AFFECTED ENTRIES
   [Schedule A: every entry, with entry number, date, port,
   product, quantity, declared value, declared classification,
   corrected classification/value/origin, duty paid, duty
   owed, and the difference.]

4. LOSS OF DUTIES
   Total additional duties owed: $__________
   [Schedule A totals.]

5. TENDER
   [Enclosed check / wire reference] in the amount of
   $__________, representing the actual loss of duties.

6. CORRECTIVE ACTION
   [What has been changed: procedures, training, systems,
   personnel, broker instructions. Attach the revised
   procedure.]

7. PROSPECTIVE COMPLIANCE
   [Confirmation that entries from [date] forward reflect the
   corrected treatment.]

Drafting notes.

File the shell the day you decide. The disclosure date is what matters, and quantification takes weeks.

Scope paragraph 1 broadly. A disclosure covering "insulated jackets" does not protect entries of insulated vests with the same error. This is the most consequential drafting decision in the letter.

Paragraph 6 of the supplement is read carefully. A disclosure with a documented corrective action is treated differently from one without.

The arithmetic. At negligence, exposure under 19 U.S.C. § 1592 is up to two times the lost duties; on a valid prior disclosure, it is interest. At gross negligence, up to four times; on disclosure, interest. The decision is rarely close.

12. Protest outline

PROTEST — 19 U.S.C. § 1514; 19 C.F.R. Part 174
Filed within 180 DAYS after liquidation — no extension

Protestant: __________  IRS No.: __________
Entry number(s) and liquidation date(s): __________
Port: __________
Amount at issue: $__________

I.   DECISIONS PROTESTED
     [Identify each decision: classification, value, rate,
     origin, marking, exclusion, or other. Be specific — a
     protest reaches only the decisions it identifies.]

II.  STATEMENT OF FACTS
     [The merchandise; the entry; CBP's action; the basis
     stated by CBP if any.]

III. THE CORRECT TREATMENT
     [What the classification, value, or origin should be.]

IV.  ARGUMENT
     A. [Legal basis — GRIs, notes, ENs, rulings, decisions]
     B. [Address CBP's stated basis directly]
     C. [Distinguish contrary rulings]

V.   REQUEST FOR FURTHER REVIEW
     [If seeking review by a higher CBP authority: state the
     grounds — the decision is inconsistent with a ruling or
     decision, involves a question not previously ruled upon,
     or involves facts or legal arguments not considered.]

VI.  RELIEF REQUESTED
     Reliquidation with a refund of $__________ plus interest.

EXHIBITS
     Entry documents; invoices; specifications; photographs;
     laboratory analysis; rulings relied upon.

[ ] Accelerated disposition requested (deemed denied after 30
    days if CBP does not act, permitting suit in the Court of
    International Trade under 19 U.S.C. § 1515)

Drafting notes.

Section I must be specific. A protest reaches only the decisions it identifies, and a general objection to "the liquidation" may not preserve a classification argument.

Section IV.C matters for the same reason it matters in a ruling request: CBP will find the contrary rulings, and the protest that addresses them is the credible one.

The accelerated disposition request is a strategic choice. It forces a decision or a deemed denial, which opens the door to the Court of International Trade — where classification questions are reviewed de novo.

Calendar liquidation dates for every entry. The 180-day period is the deadline importers miss most often, and it cannot be extended.

13. Quick reference — deadlines and periods
