Can CBD Ship to My State? Federal Rules, USPS and State Law

In most cases, yes, hemp CBD can be shipped to you within the United States, but "most" is doing real work in that sentence. Under federal law, hemp that meets the legal definition is a lawful agricultural product, and the U.S. Postal Service allows hemp-based products, including CBD, to be mailed domestically when the mailer follows the conditions in its rules. Your state can still set its own rules for hemp products, and the federal definition of hemp itself is changing in two steps in late 2026.

So the practical answer depends on three things: whether the product meets the federal definition of hemp, whether the seller and carrier are following their rules, and what your own state allows. Sellers answer the third question in their shipping policies, which is why a store may refuse orders to certain states.

I am a licensed California cannabis attorney and one of Proof's two founders. Proof sells hemp CBD online, so weigh this piece with that in mind. What follows describes the federal and postal rules as of 25 September 2026. It is general information, not legal advice. For a question about your own situation, talk to a lawyer licensed in your state.

The federal picture, as of 25 September 2026

The 2018 Farm Bill defined hemp as cannabis "with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis" (7 U.S.C. 1639o, Cornell LII). That is the definition in force today.

The same law addressed moving hemp between states. A note to that section, from Section 10114 of the 2018 act, says: "No State or Indian Tribe shall prohibit the transportation or shipment of hemp or hemp products produced in accordance with" the federal hemp program "through the State or the territory of the Indian Tribe." That provision speaks to moving hemp through a state. Whether a product can be sold or delivered to you is also shaped by your state's own rules, and the federal hemp statute says that nothing in its state plan section preempts a state law that regulates hemp production and "is more stringent" (7 U.S.C. 1639p, Cornell LII).

The Food and Drug Administration is a separate layer again. Its position is that CBD products are excluded from the definition of a dietary supplement. Our article Is CBD FDA approved? covers that side.

What changes in November and December 2026

Section 781 of the FY2026 agriculture appropriations act (Public Law 119-37, signed 12 November 2025) rewrites the federal definition of hemp. As of 25 September 2026, it applies in two steps:

• From 12 November 2026: intermediate and final products containing cannabinoids that the plant cannot naturally produce are no longer hemp.
• From 11 December 2026: the rest applies, including a total THC standard that counts THCA, a cap of 0.4 mg of total THC per container on final products, and the exclusion of natural cannabinoids "synthesized or manufactured outside the plant."

The December date comes from a stopgap funding law, Public Law 119-103, signed 2 September 2026 (bill text, Congress.gov), and it could move again. The new definition covers products intended "for human or animal use," including topicals. Our explainer on the 2026 hemp law changes walks through the text in detail. For shipping, the point is simple: a product that can be mailed as hemp today may not qualify after the new definition applies, so the lab report behind it matters.

What USPS Publication 52 says

The Postal Service sets its mailing rules for restricted items in Publication 52. As of 25 September 2026, the current edition is dated August 2026, and section 453.37, "Hemp-Based Products," says that "hemp" refers to the federal definition, including 7 U.S.C. 1639o, "or any successor provision" (USPS Publication 52, section 453.37).

It then says hemp and hemp-based products, including CBD, with a THC concentration "not exceeding a 0.3 percent limit are permitted to be mailed domestically only when the mailer":

1. "Complies with all applicable federal, state, and local laws, including U.S. Department of Agriculture approved plans for hemp production, processing, distribution, and sales (7 CFR Part 990)."
2. "Retains records establishing compliance with such laws and plans, including laboratory test results, licenses, or compliance reports, for no less than 3 years after the date of mailing."

And: "Shipments of hemp and hemp-based products, including CBD, are prohibited in international mail, including items for delivery to overseas Army Post Office, Fleet Post Office, and Diplomatic Post Office addresses (APO/FPO/DPO)."

Three things follow for a shopper. The mailer, not you, carries the compliance and record-keeping duties. State and local law is written into the USPS condition itself. And the section points to the federal definition "or any successor provision," so how USPS applies it after the Section 781 changes is something to watch rather than predict. Private carriers set their own terms, which I have not reviewed here.

Why your state still matters

States regulate hemp products in their own ways and can change their rules at any time, which is why we do not publish a state-by-state table: it would go out of date quickly, and a summary is no substitute for the rule itself.

Before you order, check:

• Your state's department of agriculture (often the hemp program) and health department (often food and consumer product rules).
• The seller's shipping policy. A seller that lists states it will not ship to has usually made that call based on the law there.
• Local rules, if you live somewhere with its own ordinances.

How to check before you order

A quick checklist for any CBD store:

• The shipping policy states where the store ships and where it does not.
• The product's certificate of analysis (COA) matches your batch and reports total THC, ideally in milligrams per container as well as percent.
• The store ships only within the U.S. (consistent with Publication 52) and does not offer delivery to APO, FPO or DPO addresses by mail.
• The checkout confirms the shipping address is eligible before you pay.

Our guide to how to buy CBD online safely covers the rest of the store checks.

Proof's own shipping policy

As of 25 September 2026, Proof's shipping policy says we ship only within the United States and that, "due to state laws in MT, we do not currently ship to Montana." Orders placed to Montana are canceled. Orders usually ship within 1 to 3 business days from Northern California, and standard shipping usually takes 3 to 7 business days. The finished-product COAs for our products, dated May 2025, report total THC as not detected; you can read them on our lab testing page.
