Most launch checklists are in the wrong order. Here is the sequence, with the deadlines that are not yours to move.

Key takeaways

• Sequence by lead time, not by logical order. A trademark is reported at eight to fourteen months to registration; third-party product testing takes weeks; a GS1 prefix is immediate. Start the slow things first.
• Several decisions are irreversible or expensive to reverse: Vine enrolment is once per ASIN for its lifetime, permanent branding is a production decision, and packaging dimensions set your size tier permanently.
• Documents you collect at purchase serve six later systems. Documents you try to collect afterwards frequently cannot be obtained in the window you are given.
• The cost side is knowable before you commit; the demand side is a forecast. Most launch failures are cost failures dressed as demand failures.
• This page is a sequence and an index. Each step links to the guide where the figures and sources sit.

Launch guidance usually runs in the order the tasks feel natural: find a product, find a supplier, make a listing, run ads. That order maximises the chance of discovering a blocker after you have paid for inventory.

This is the same work ordered by who controls the clock.

01The lead times you do not control

Before anything else, the durations that decide the sequence:

Step	Reported lead time
Trademark to full registration	8–14 months (weeks via the pending-application route)
Third-party product testing	Weeks, per packaging design and standard
VAT registration where required	Weeks to months, per country
Ungating approval	Days to weeks, plus invoice age requirements
Dangerous goods review	2–5 business days, with inbound blocked
GS1 GTINs	Immediate
Brand Registry enrolment	About two weeks once the trademark checks out

Everything above the last two lines is a reason to start earlier than feels necessary.

02Phase 1 — Decide, before spending

1. Validate cost, not just demand. The cost side is knowable from published schedules; demand is a forecast. Spending two weeks on search volume and estimating the fee stack is the wrong way round. → Product research

2. Get packaged dimensions from the supplier. They set the size tier, the fulfilment fee and every layer of the storage bill, permanently. → Storage

3. Check the price against the bands. Under $10, $10–$50, above $50. A product that only works at a price sitting just above a boundary is fragile. → Price bands

4. Check the gates. Category, brand and ASIN. Sourcing inventory for a gated product and then seeking approval is the expensive order. → Ungating

5. Check for dangerous goods. Anything with a lithium cell, pressurised, flammable, reactive or strongly magnetic. → Hazmat

6. Build landed cost, not invoice price. Duty, user fees, broker, bond, prep. → Landed cost

03Phase 2 — Start the slow clocks

Run these in parallel with everything below.

7. File the trademark if you are building a brand. Eight to fourteen months, or weeks to Brand Registry access via a pending application. → Brand Registry

8. Buy GS1 GTINs — one per variation. Directly from GS1; resold codes fail verification. → Barcodes

9. Commission product testing where required. CPC or GCC, from an accepted laboratory. Since 8 July 2026 the certificate is also filed electronically at import. → Compliance

10. Sort insurance if you expect to cross the threshold — reported at $10,000 in sales across three consecutive months. → Insurance

04Phase 3 — Supplier, and the documents

11. Verify the supplier before paying. Business licence at the source registry, scope of business, bank account matching the licensed entity. → Supplier verification

12. Get a sample invoice and check the fields. This is the step almost nobody does, and it decides six later outcomes. → The supplier invoice

13. Specify permanent branding. Printed, moulded, embroidered or engraved. Stickers are reported as the most common Brand Registry rejection cause — and fixing it means another production run. → Brand Registry

14. Agree the Incoterm, the named place and the version, in writing. And confirm whose name goes on the customs entry. → Incoterms

15. Arrange prep. Amazon stopped doing it on 1 January 2026. Supplier, prep centre or in-house — decide before the goods ship. → Prep

05Phase 4 — Import

16. Classify the product. Ten digits, documented reasoning. The importer of record carries the liability and cannot delegate it. → HTS classification

17. Sort the entry type and the bond. Type 11 informal or Type 01 formal. → Entry types

18. Budget for an examination. Reported at $150 to $2,500 and beyond, before demurrage, and the importer pays. → Customs holds

06Phase 5 — Listing, before advertising

19. Build the listing for conversion. Conversion is consistently described as the dominant ranking signal, and it is the half you control. → Listing optimisation

20. Fill every field. Backend search terms within 249 bytes, Item Highlights, attributes. Free indexing, routinely left empty.

21. Deploy A+ Content once Brand Registry is live. Reported as the fastest conversion impact among the registry tools. → Brand tools

22. Decide on Vine — carefully. Once per ASIN, for its lifetime. Enrolling before the product and listing are finished buys permanent, detailed criticism. → Vine

07Phase 6 — Then advertise

23. Calculate break-even ACOS per SKU, after all fees. Not per catalogue. → PPC benchmarks

24. Start with Sponsored Products. Reporting describes the other formats as amplifying a working funnel rather than fixing a broken one.

25. Mine search-term reports for organic terms. Paid discovers, organic keeps.

08Phase 7 — The things that decide whether it survives

26. Set a reorder trigger covering supplier lead time, transit, customs and Amazon receiving — because the low-inventory fee is charged on sales made while thin. → Low inventory

27. Model cash on delivery date. DD+7 means reported order-to-bank of 14 to 27 days for FBA. → DD+7

28. Watch ODR daily. One metric can suspend an account on its own, and at low order volume a single defect is a large percentage. → Order defect rate

29. Diarise the 150-day inventory review. The aged-inventory trigger is reported at 180 days, and a removal order takes time. → Removal decision

30. Read return reason codes monthly. They separate an expectation gap from a product problem, and they are the specification for your next listing revision. → Returns

09The five decisions that are hard to reverse

Worth isolating, because everything else can be fixed later:

1. Packaging dimensions — set the size tier and every storage layer, permanently
2. Permanent branding — a production decision, not a listing one
3. Vine enrolment — once per ASIN, for its lifetime
4. The supplier you can or cannot get documents from — decides six later systems
5. The trademark name — must match everywhere, exactly, including punctuation

Everything on that list costs a production run or a lifetime to change. Everything else is an afternoon.

Frequently asked

What should I do first?

Start the slowest clock. If you are building a brand, that is the trademark at a reported eight to fourteen months. Meanwhile, validate the cost side — it is knowable, and demand is not.

Why is packaging so early in the sequence?

Packaged dimensions set the size tier, which sets the fulfilment fee, and cubic feet multiply every layer of the storage bill. Changing it later means another production run.

When should I enrol in Vine?

After the product and the listing are finished, never before. Enrolment is once per ASIN for its lifetime, and Vine reviews are detailed, honest and permanent.

Do I need a trademark to start?

No — Brand Registry is not required simply to sell. But the tools it unlocks, and the barcode position after 31 March 2026, make it worth starting early because of the lead time rather than the urgency.

What is the most common launch mistake?

Validating demand precisely and cost approximately. The cost side comes from published schedules and your own supplier quote; the demand side is a forecast. Most launch failures are cost failures.

How long does a launch actually take?

The gating item is usually testing, trademark or supplier lead time rather than anything you control. Working backwards from those, rather than forwards from enthusiasm, is what this sequence is for.
