Sawmills

NAICS 321113 · Wood Product Manufacturing · SBA size standard: 550 employees

Sawmills receive logs, cut them into lumber according to grade and dimension orders, dry and sort the output, and ship to lumber yards or direct customers. For a mill that buys mixed hardwood and softwood logs and fills weekly dimension and grade orders, the specialists turn supplier delivery notices and customer orders into a cutting schedule, turn the cutting schedule into a drying and finishing plan, and turn finished tallies into shipping documents and reorders. Log scaling, grade rules, kiln schedules and safety calls stay with the sawyer and grader.

  • Kiln drying cycles with strict time, temperature and moisture-content schedules
  • Lumber grading under NHLA or SPIB rules with tally sheets and grade stamps
  • Chain-of-custody, harvest permits, air-quality permits and OSHA safety logs
  • Seasonal shifts in log supply and customer demand for green versus dried lumber
  • Heavy equipment maintenance tracking and blade sharpening schedules

Workflows

Log intake and scaling

Starts when: A log truck arrives at the yard or a supplier sends an advance manifest

  1. Record species, length, diameter and defect notes for each load
  2. Scale the load and assign a mill ticket number
  3. Update the log yard inventory by species and grade class
  4. Draft the scale ticket for supplier payment
  5. Flag any loads needing immediate processing to avoid degrade

Watch for: Accurate scaling determines payment to the supplier; Species and defect data drive the cutting decision

Cutting schedule and yield planning

Starts when: Weekly or when new orders arrive

  1. Combine open customer orders by dimension, grade and species
  2. Match orders against current log deck inventory
  3. Run yield scenarios to maximize grade recovery
  4. Produce a daily sawing list with target cant sizes and blade settings
  5. Update live tallies as boards come off the saw

Watch for: Saw kerf and taper must be accounted for in every run; Grade targets affect how cants are turned and edged

Kiln drying and inventory movement

Starts when: End of each green chain run and on a weekly cadence

  1. Group green lumber by thickness, species and initial moisture estimate
  2. Assign kiln charges with target schedules and load tags
  3. Track kiln temperature, humidity and moisture samples
  4. Move dried loads to the yard or planer when target moisture is reached
  5. Update inventory from green to dry status

Watch for: Drying schedules vary by species and season; Over-drying or under-drying creates degrade that must be caught early

Grading, tallying and stamping

Starts when: After drying or planing

  1. Apply NHLA or SPIB grade rules to each board
  2. Tally lengths, widths and grades into bundles
  3. Generate grade stamp and bundle tag data
  4. Reconcile actual yield against the cutting schedule
  5. Flag any off-grade material for secondary markets

Watch for: Grade accuracy directly affects selling price; Tally sheets must match physical bundles for shipment

Order fulfillment and shipping

Starts when: When a customer order is ready or on a set ship day

  1. Pull bundles that satisfy the order specifications
  2. Prepare bills of lading and load lists
  3. Draft carrier dispatch and delivery windows
  4. Record load weights and securement details
  5. Send shipment confirmation and invoice draft

Watch for: Truck and rail weight limits must be observed; Moisture content at shipment affects acceptance

Equipment maintenance and blade care

Starts when: Daily, weekly and after set hours of run time

  1. Log saw, edger and planer run hours
  2. Schedule blade changes and sharpening
  3. Track bearing, chain and hydraulic service intervals
  4. Generate work orders for mechanics
  5. Keep maintenance history tied to each piece of equipment

Watch for: Blade sharpness and alignment affect yield and safety; Downtime must be minimized during peak cutting season

Regulatory and safety documentation

Starts when: Every operating day and on renewal dates

  1. Generate daily safety and housekeeping checklists
  2. Log chain-of-custody and harvest permit details
  3. Track air-quality and wastewater permit parameters
  4. Remind on renewal dates for licenses and insurance
  5. Compile monthly summary reports for owner review

Watch for: Rules differ by state and federal jurisdiction; The mill owner confirms which permits and reports apply
