Manufacturing Under 280E: A Different Challenge
Cannabis manufacturers face a unique COGS challenge compared to cultivators. Where a cultivation operation has a relatively straightforward production process (grow, harvest, dry, trim, package), manufacturing involves multiple sequential processes, each with its own inputs, equipment, labor, and yield characteristics.
A single manufacturing facility might run hydrocarbon extraction, ethanol extraction, CO2 extraction, distillation, formulation, edibles production, and packaging, all under one roof. Each process has different cost drivers, and each product line has a different cost structure. Allocating shared costs across these product lines in a way that is accurate, defensible, and consistent is the core challenge of manufacturing COGS under 280E.
The good news is that manufacturing operations typically have a higher proportion of total costs that qualify as COGS compared to retail operations. The production-intensive nature of manufacturing means more of your expenses are directly tied to producing inventory, which means more costs can offset revenue under 280E.
Which Extraction and Processing Costs Qualify
Direct Materials
All raw materials that are consumed in the production process qualify as COGS. For manufacturing, this includes cannabis biomass or trim (your primary input), extraction solvents (butane, propane, ethanol, CO2), carrier oils and diluents (MCT oil, hemp seed oil for tinctures and vape formulations), edibles ingredients (sugar, gelatin, flavoring, coloring), and packaging components (cartridges, batteries, jars, child-resistant containers, labels).
Importantly, solvents qualify as direct materials even though most of the solvent is recovered and reused. The portion that is lost during each extraction run is a direct material cost. The cost of solvent replacement and top-off should be tracked per batch.
Process consumables also qualify. This includes filter media, extraction column packing, gaskets and seals that are replaced periodically, lab supplies used in quality testing, and cleaning chemicals used for equipment sanitation between batches.
Direct Labor
Wages and benefits for employees directly involved in production are direct labor costs includable in COGS. For manufacturing operations, this includes extraction technicians who operate extraction equipment, refinement and distillation operators, edibles kitchen staff (cooks, confectioners, bakers), formulation chemists who develop and mix product formulations, packaging line workers, and in-process quality control technicians.
Track time by batch or by production run. If a technician spends six hours on a distillation run, those hours are allocable to the specific batch being distilled. Use timesheets or an electronic time-tracking system that records time at the batch level.
Equipment Costs
Manufacturing equipment is typically more expensive and more specialized than cultivation equipment. Closed-loop extraction systems, short-path distillation units, rotary evaporators, wiped-film evaporators, commercial kitchen equipment, filling machines, and labeling equipment all represent significant capital investments.
Depreciation on production equipment is allocable to COGS. Calculate depreciation on a per-hour or per-batch basis rather than a straight monthly allocation. This ensures that batches using more equipment time bear a proportionally higher share of equipment costs.
Maintenance and repair costs for production equipment also qualify. Annual maintenance contracts, replacement parts, calibration services, and emergency repairs on production machinery are production costs under Section 263A.
Allocation Methodology for Multi-Product Facilities
The Allocation Problem
A manufacturing facility producing five different product types on shared equipment presents an allocation problem. The extraction system processes biomass for vape cartridges, concentrates, and tinctures. The packaging line handles multiple product formats. Facility costs (rent, utilities, insurance) support all product lines simultaneously.
Allocating these shared costs requires a consistent methodology that distributes costs in proportion to each product line's consumption of shared resources.
Equipment-Based Allocation
The most defensible approach for shared equipment is time-based allocation. Track the hours each piece of equipment spends on each product type. If your extraction system runs 160 hours in a month and 60 of those hours produce material for vape cartridges, 40 hours for concentrates, and 60 hours for edibles input, then vape cartridges absorb 37.5% of that month's extraction equipment depreciation and maintenance costs.
This requires an equipment utilization log. Every production run should be logged with the start time, end time, equipment used, and product type. This log serves double duty as both a cost allocation record and a production efficiency tool.
Labor-Based Allocation
For shared labor (employees who work across multiple product lines), allocate based on time spent on each product type. A production supervisor who oversees both extraction and edibles production should have their compensation allocated based on the proportion of time spent on each.
Facility-Based Allocation
Allocate facility costs (rent, utilities, property tax, insurance) based on square footage dedicated to each production activity. If your extraction lab occupies 2,000 square feet and your edibles kitchen occupies 1,500 square feet out of a 5,000-square-foot production floor, extraction absorbs 40% and edibles absorb 30% of production facility costs.
For utility costs, sub-metering provides the most accurate allocation. Extraction equipment, commercial ovens, and HVAC systems for different production zones may consume very different amounts of electricity. Sub-meters eliminate the need to estimate.
Production Process Documentation
Mapping the Production Flow
Create a written production flow document that traces every product from raw material intake through finished goods. For a vape cartridge, this might look like: biomass receiving and intake weighing, extraction (hydrocarbon, ethanol, or CO2), winterization and filtration, decarboxylation, distillation (first pass and second pass), terpene reintroduction and formulation, cartridge filling, capping and packaging, COA testing, and finished goods storage.
Each step should identify the inputs consumed, the labor required, the equipment used, and the expected yield. This document becomes the backbone of your COGS allocation and the primary exhibit in any audit defense.
Standard Operating Procedures
SOPs for each production process serve two purposes. They ensure consistent product quality, and they provide contemporaneous evidence that your production activities are genuine manufacturing operations with real costs. SOPs should reference the equipment used, the materials consumed, the time required, and the quality checkpoints at each stage.
Batch Records
Every production batch should generate a batch record that documents the raw materials used (with METRC tag references), the process steps performed, the time spent on each step, any deviations from standard procedures, in-process test results, final yield, and COA test results.
These batch records are the transaction-level evidence that supports your COGS calculations. They connect your financial records to your METRC records and your quality records in a single, auditable trail.
Handling Production Losses and Failed Batches
Yield Loss as a Production Cost
Cannabis manufacturing involves significant yield loss at multiple stages. Extraction yield, winterization loss, distillation loss, and formulation spillage all reduce the quantity of finished product below the theoretical maximum.
Under GAAP and under Section 263A, normal production losses are capitalized into the cost of the remaining inventory. If you start with 100 pounds of biomass and produce 15 pounds of distillate, the cost of the 100 pounds of biomass (plus all processing costs) is allocated across the 15 pounds of finished product. The 'lost' 85 pounds of biomass does not generate a separate expense; its cost is embedded in the per-unit cost of the 15 pounds that survived.
Abnormal losses (spoilage, waste, or destruction due to unusual events) should be expensed as a period cost. However, under 280E, these period costs are not deductible. The distinction matters primarily for financial statement accuracy and internal management reporting.
Failed COA Batches
When a batch fails COA testing and cannot be remediated, the total cost of that batch (materials, labor, equipment, overhead) is a production loss. If the failure rate is normal for your process (typically 2% to 8% depending on product type), the cost of failed batches is a normal production cost that gets capitalized into the remaining inventory.
Track failure rates and costs by product type. This data supports both your COGS calculation and your quality improvement program.
Common Mistakes in Manufacturing COGS
Under-Allocating Facility Costs
Some manufacturers allocate only direct materials and direct labor to COGS, ignoring the Section 263A requirement to capitalize indirect production costs. For a manufacturing operation with significant facility and equipment costs, this can leave hundreds of thousands of dollars of legitimate COGS on the table.
Inconsistent Allocation Bases
Using different allocation methods for different cost categories without a documented rationale creates audit risk. If you allocate equipment costs based on time but facility costs based on revenue, the IRS may question why you did not use a consistent basis.
Ignoring Shared Costs
Costs shared between production and non-production activities must be properly split. If your facility manager oversees both the production floor and the administrative offices, their compensation should be allocated based on time spent on each, not assigned entirely to one or the other.
Poor Batch Records
Without batch-level records tying costs to specific production runs, your COGS allocation is based on estimates rather than actual data. Estimates are harder to defend in an audit and may not accurately reflect your true cost structure.
The Bottom Line for Manufacturers
Manufacturing operations typically have the highest percentage of total costs that qualify as COGS because nearly everything in the facility supports production. A well-executed 263A cost study for a cannabis manufacturer commonly captures 60% to 75% of total facility costs as COGS, compared to 40% to 60% for a cultivator and 15% to 25% for a retailer.
This makes proper COGS allocation even more valuable for manufacturers. The difference between a basic COGS calculation and a comprehensive 263A study can mean $200,000 to $500,000 or more in annual tax savings for a mid-size manufacturing operation. That is cash that stays in your business instead of going to the IRS, and in an industry where margins are tight and 280E is relentless, every dollar matters.
