Washington Hemp and CBD Legal Guide: $1,200 WSDA Producer License and the Ban on Detectable THC Outside Cannabis Stores

Updated October 26, 2026. Federal hemp rules are changing in stages starting November 12, 2026, and a reported September 2026 appropriations law may move some dates to December 11, 2026. Confirm current dates with USDA and the Washington State Liquor and Cannabis Board (LCB) before you make production, inventory or sales decisions.

If you plan to grow hemp, sell CBD or sell any product derived from hemp in Washington, you need to answer three separate questions. First, do you need a state hemp license? Second, is your product legal where you plan to sell it? Third, what business structure and tax registrations will hold the license and carry the sales? This guide walks through each question. It is a practical starting point for anyone searching for a Washington hemp license, and it points you to the agency that handles each step.

Start with one question: are you growing, processing or selling?

Washington treats hemp activity differently depending on what you do with the plant and the product:

• Growing hemp: Requires a hemp producer license from the Washington State Department of Agriculture (WSDA). WSDA licenses only growers.
• Processing hemp: Processor registration with WSDA is voluntary. It is a business registration, not a license.
• Selling products with detectable THC: Only licensed cannabis retailers may sell them. This includes delta-8 products. The LCB licenses those retailers.
• Selling CBD products: Limited to specific product types, as explained below.

Many businesses do more than one of these things. A farm that grows hemp and sells finished CBD products, for example, needs to satisfy the grower rules, the product rules and the general business rules at the same time. Treat each one as a separate checklist item.

The WSDA hemp producer license: $1,200 per year

The Washington hemp producer license costs $1,200 a year under WAC 16-306-140. The key points for planning are these:

• Application window: Applications are accepted from January 1 to March 31.
• Late applications: WSDA accepts late applications under WAC 16-306-040, but they keep the same expiration date as on-time applications. A late applicant therefore gets a shorter effective license term for the same $1,200 fee.
• Background check: Applicants must complete a background check as part of the process.

Build your timeline backward from March 31. If you intend to plant in the spring, the license should be in place before the growing season begins. Ask WSDA what activity is permitted while an application is pending, because the answer determines whether you can start preparing land, ordering seed or moving material before the license is issued.

Processor registration: $1,200 for three years

Processor registration costs $1,200 for three years under WAC 16-306-055. It is voluntary, and it is a business registration rather than a license. It does not authorize you to grow hemp. Whether it makes sense for you depends on your buyers, your lenders and how you plan to demonstrate compliance. Ask WSDA what the registration covers before you file so you do not assume it replaces the grower license or any other requirement.

The 0.3% THC limit

Under WSDA's definition, hemp contains 0.3% delta-9 THC or less by dry weight. Because the limit is measured on dry weight, a product that looks compliant on the shelf can still fail the standard. Plan for testing from the start of production rather than treating it as a final step. Ask WSDA which testing requirements apply to your license before harvest, since the answer affects your timing, your costs and what you can do with the crop if it tests above the limit.

The ban on detectable THC outside cannabis stores

Under SB 5367 (2023), only licensed cannabis retailers may sell products with detectable THC. The rule specifically covers delta-8 THC. In practical terms, a CBD shop, smoke shop, convenience store or online seller cannot sell delta-8 gummies, vape cartridges or other hemp-derived products that contain detectable THC, even if the label calls them hemp. This is the rule that catches many businesses off guard, because hemp products have been sold in general retail settings for years.

If your product line includes anything with detectable THC, your realistic options are to sell it through a licensed cannabis retailer or to remove it from your line. Questions about how the rule applies to a specific product belong with the LCB, which licenses cannabis retail in Washington.

CBD rules: what you can and cannot sell

WSDA states that CBD may not be added to food, beverages or dietary supplements. For consumers, WSDA's hemp FAQ and FDA policy allow only CBD topicals. In practice, a CBD tincture, CBD coffee or CBD capsule sold as a supplement falls outside the state's stated position, and a topical such as a cream or lotion is the category WSDA identifies as permitted.

Check the WSDA hemp FAQ before you launch any ingestible line, and review the current FDA policy on CBD as well. Do not rely on a supplier's marketing claims about what is permitted. The seller carries the compliance risk for the products it puts on the shelf.

Federal changes are coming in stages

The federal hemp redefinition (P.L. 119-37) takes effect in stages starting November 12, 2026. A September 2026 appropriations law is reported to move the total-THC standard and the 0.4 mg per-container cap to December 11, 2026. Treat those dates as unsettled until you confirm them with USDA and LCB guidance.

Federal and state rules both apply. A product that meets the federal definition may still be restricted under Washington law, and Washington's rules on detectable THC do not change because of federal dates. Build your product plan around the stricter of the two standards that applies to you.

Common mistakes that cause problems

• Selling delta-8 in a general retail store. Under SB 5367, detectable THC products belong with licensed cannabis retailers.
• Adding CBD to food or drinks. WSDA says CBD may not be added to food, beverages or dietary supplements.
• Planting before the license is issued. Confirm what WSDA allows while an application is pending.
• Forming the business after the sales start. Corporations and LLCs must file with the Secretary of State before the general business license application.
• Missing the annual report. An LLC or corporation that files late owes a delinquency fee, making the total $95 instead of $70.

Setting up the business behind the license

A hemp license attaches to a business, so you still need the standard formation and tax registrations. Washington has no corporate income tax and no personal income tax on wages. Instead, most businesses pay the state business and occupation (B&O) tax, a gross receipts tax with more than 50 activity classifications and no deduction for labor, materials or other costs. About 54 cities also levy their own B&O tax, which the Department of Revenue does not administer. The state sales tax rate is 6.5%.

Choose a structure and file with the Secretary of State

Sole proprietors and general partnerships do not file with the Secretary of State. An LLC is formed by filing a Certificate of Formation with Initial Report through the Corporations and Charities Filing System (CCFS) at https://ccfs.sos.wa.gov/ for $180. A corporation files Articles of Incorporation with Initial Report for the same $180.

Every LLC and corporation must designate a registered agent in Washington with a physical street address. PO Boxes and private mailbox addresses are not accepted. The annual report costs $70 and is due by the last day of the month in which the entity was formed or registered, every year. It may be filed up to 180 days early. A late filing carries a delinquency fee, for a total of $95.

Entity choice affects liability, taxes and how investors view the company. This is general information, so confirm your structure with a qualified attorney or CPA before you file.

Register with the Department of Revenue

The Business Licensing Service (BLS) inside the Department of Revenue runs Washington's general business license. One Business License Application issues your 9-digit Unified Business Identifier (UBI) and handles trade names and state and city endorsements. The processing fee is $50 to open a business, plus separate endorsement fees. Corporations, LLCs, LLPs and partnerships must file with the Secretary of State before submitting this application.

You need the business license if you sell anything subject to sales tax, if you expect gross income of $12,000 or more per year, or if you operate under a name other than your full legal name. Online applications generally take about 10 business days, and two to three weeks longer when city or state endorsements need approval. Mailed applications can take up to six weeks.

If you sell under a brand name, register it as a trade name with the BLS at https://dor.wa.gov/manage-business/grow-business/register-trade-names. Trade names are not filed with the Secretary of State or the county. The fee is $5 for each trade name, plus the $50 processing fee to open a business, or $10 when the filing adds a trade name to an existing business.

Check local permits and zoning

Washington has 39 counties and 281 incorporated cities and towns. Depending on where you grow, process or sell, a city or county may require its own license, zoning approval or local B&O registration. Health district permits may also apply if your operation touches food or beverages. Contact your city or county clerk and your local health district before you sign a lease or open a location.

Step-by-step checklist

1. Decide whether you will grow, process, sell, or some combination of these.
2. If you will grow, plan a WSDA hemp producer license application between January 1 and March 31, and budget $1,200 per year.
3. Decide whether to file voluntary processor registration at $1,200 for three years.
4. Confirm whether any product you plan to sell contains detectable THC. If it does, plan to sell it through a licensed cannabis retailer.
5. Remove CBD from any food, beverage or dietary supplement line before you sell it.
6. Form your LLC or corporation through CCFS, appoint a registered agent, and calendar the annual report.
7. File the Business License Application for your UBI and any trade name.
8. Register for B&O tax, then check for city B&O tax, city or county licenses and health district permits.
9. Check the federal hemp dates with USDA and LCB guidance before you finalize your product plan.
