Amazon FBA vs FBM:
Who Is the Producer?

You sell with FBA. Or FBM. Or MCF. Or all three.

None of them changes who's on the hook for packaging EPR — for your product's packaging.

There is one narrow exception, and it applies only in five states, and only to the outer shipping box. Everything else stays where the statutes put it: with the brand owner.

Fulfillment moves boxes. Producer status follows brands.

This piece walks through why, and gives you a scenario-by-scenario answer. If you haven't yet confirmed whether you're a producer at all, read Does California SB54 Apply to Amazon FBA Sellers? first — that's the upstream question this one answers a follow-up to.

1. Quick recap: FBA, FBM, MCF

Skip this section if you already know how the three work.

FBA (Fulfillment by Amazon). Amazon holds your inventory in its warehouses, picks and packs the order, ships it to the customer in an Amazon-branded shipping box. You never touch the outbound package.

FBM (Fulfilled by Merchant, sometimes called MFN — Merchant Fulfilled Network). Amazon lists your product and processes the order. You (or your 3PL) hold inventory, pack it, and ship it. Amazon is the sales channel; the fulfillment is yours.

MCF (Multi-Channel Fulfillment). Amazon holds your inventory and ships it, but the order came from somewhere else — usually Shopify, your DTC storefront, wholesale channel, or another marketplace. In Seller Central reports, MCF orders show up under sales-channel = Non-Amazon or Non-Amazon US.

All three flow through Amazon in different ways. None of the three changes producer status for your product's packaging. Here's why that doesn't matter.

2. Why fulfillment channel doesn't determine producer status

The California SB 54 producer definition, at PRC § 42041(w), is a three-tier hierarchy that turns on brand ownership. Tier one: the manufacturer who owns (or licenses) the brand on the package. Tier two: the brand owner or exclusive licensee if there's no tier-one match in California. Tier three: the seller or distributor into the state if neither of the above applies.

Nothing in that hierarchy asks about fulfillment channel. Nothing asks who packed the item, who warehoused it, or who trucked it to the customer. It asks about the brand on the package. That's it.

That's why the answer looks the same across the three fulfillment models:

• Own brand + FBA. You own the brand. You're the producer. Amazon is your fulfillment partner, not your compliance shield.
• Own brand + FBM. You own the brand. You're the producer. You also happen to pack and ship the box, but that doesn't change producer status for product packaging (see §3 for the shipping-box nuance).
• Own brand + MCF. You own the brand. You're the producer. Amazon warehouses and ships for you into a non-Amazon sales channel — still doesn't change producer status. The obligation follows the packaging into whichever state the customer sits in, regardless of where the order originated.

The MCF case is the sharpest test. A Shopify order, fulfilled from an Amazon warehouse, in an Amazon-branded shipping box, going to a customer in California — that's Amazon doing almost all the physical work. Producer status for the product packaging still stays with you. The state doesn't care about the warehouse. It cares about the brand on the package.

Full statutory text and the three-tier hierarchy are covered in Does California SB54 Apply to Amazon FBA Sellers? §3 if you want the citation-level detail. For this piece, the point is narrow: fulfillment channel simply isn't part of the producer test.

3. The two nuances

There are two places where fulfillment channel actually matters. Both are narrow.

Nuance 1: The outer shipping box in five states.

Oregon, Colorado, Minnesota, Washington, and Maryland split producer responsibility for e-commerce packaging into two parts. Inner packaging (what your product actually sits in) stays with the brand owner. The outer shipping box goes to whoever packages and ships the item.

Practical impact: for FBA and MCF orders, the outer Amazon-branded box is Amazon's producer responsibility in those five states — not yours. For FBM orders, the shipping box is yours because you're the party that packages and ships.

Your product's own packaging is still yours in all cases. This nuance only touches the outer shipping carton in five specific states.

Nuance 2: Contractual reassignment (Minnesota, Washington, Maryland).

Three states allow producer responsibility to be contractually reassigned from the default party to another party — provided that other party joins a Producer Responsibility Organization (PRO) and takes on the reporting obligation. Minnesota's version is the clearest (Minn. Stat. § 115A.1441):

Washington's version (RCW 70A.208.020) works the same way with two narrow carve-outs (agricultural commodities and beverage distributors). Maryland's version, after the SB 901 amendment (§ 9-2501(p)), frames it differently — as an exclusion from the producer definition rather than an affirmative reassignment — and doesn't require the assignee to join a PRO in the same clause.

What this means practically: if Amazon (or any marketplace, 3PL, or PRO) ever wanted to take on your product-packaging producer obligation in Minnesota, Washington, or Maryland, the statutory mechanism exists. Amazon has not done this. There is no publicly announced timeline. But the mechanism is there — it's the same shape as Amazon's Pay-on-Behalf program in France and Spain.

4. Scenario table — quick answers

For most Amazon sellers, the producer question resolves to one of these rows:

Note that in every row, the product-packaging column comes down to whose brand is on the package. Not who ships it. The shipping-box column varies by fulfillment channel — but only for five states, and only for the outer box.

If you sell in a state that isn't OR/CO/MN/WA/MD, the shipping-box distinction doesn't apply and both columns collapse into one: whoever owns the brand.

5. What to do with this

If you already know you're the producer for your product packaging, this piece has told you what you needed to know: your fulfillment mix doesn't change that. Move on to the data problem — how to pull state-level packaging data from Amazon reports.
