Receiving

What to check on delivery

Eleven minutes on the first three deliveries sets the tone for the whole relationship. Do this with any supplier, including us.

Write failures on the delivery ticket rather than calling — a written record is the only thing that reliably changes supplier behaviour, and we replace rejected units on the next route with no restocking charge.

Storage

Keeping pallets usable through a wet winter

Portland takes about 36 inches of rain a year and most of it lands between November and March. You do not need a building to survive that — you need three habits.

Off the ground
Two spare pallets as a base. Anything touching soil wicks water and rots from the bottom layer up.
Covered on top
A tarp that actually reaches the sides. Rain enters a stack from above, not from the side.
Air gaps, not a seal
A sealed tarp traps condensation and produces the mould problem you were avoiding. Leave the sides open.
Away from drip lines
Anything under a roofline drip edge stays wet all winter, regardless of what you cover it with.
Aligned with the wind
Stacks oriented with prevailing wind dry noticeably faster. Free, and it works.
Rotate the pile
First in, first out. The bottom of an untouched stack is where pallets go to die.
What moisture does, measured on our own scale and grading line.

Nine pounds of water per pallet is nine pounds of freight you pay to move. Across 600 units that is more than two and a half tonnes of water on a truck. Field notes on moisture

Diagnostics

Read the damage, fix the cause

Damage patterns are not random. Each one points at a specific handling behaviour, and fixing the behaviour is worth more than fixing the pallets.

Keep thirty of your own broken pallets aside for a month and photograph the damage. Patterns appear quickly. We do this analysis free with any repair quote, because a customer whose damage rate halves buys from us for a decade.

If you are selling

Six things that raise what your pile is worth

None of these require you to sort anything. They just make the pile faster for a driver and a grader to deal with, and that difference lands in the price.

  1. 01

    Get it off the dirt

    The bottom layer of a stack sitting on soil is the layer we have to write off. Two spare pallets underneath prevents it.

  2. 02

    Stack square and to one height

    Even stacks load faster, count accurately and travel without shifting. Leaning piles get counted conservatively.

  3. 03

    Keep sizes together

    You do not need to grade, but separating 48×40 from everything else takes minutes and raises the per-unit price.

  4. 04

    Pull out the obvious non-wood

    Carpet, foam-backed board, metal frames and the occasional bicycle. Composites cost us money to separate.

  5. 05

    Leave truck and forklift access

    A pile behind a locked gate at the end of a narrow alley is worth less than the same pile on a loading apron.

  6. 06

    Photograph it once

    One picture from fifteen feet tells a grader footprint, grade mix, moisture exposure and count within about 15%.

What we can and cannot take. We will always name somebody who can handle the rest.

Freight

What fits in what

Pallet counts per vehicle and container, so you can sanity-check a quote before you accept it.

Empty pallets, stacked, with typical safe stack heights. Loaded counts are governed by your product, not by the pallet.

Pallet freight is almost always weight-constrained before it is cube-constrained, which is why tare weight is a real cost line. How we price a lane

Worked example

Cost per trip, calculated properly

A real comparison for a plant shipping 600 pallets a month on a weight-sensitive lane. Copy the method, not the numbers.

Illustrative. Your lane rate, damage rate and disposal cost will differ — the point is that unit price is the smallest line in the table.

Build this yourself

One row per option, six columns: unit price, tare weight, expected trips, damage rate, rejection risk, disposal cost. Multiply out across annual volume. It takes an afternoon, the cheapest unit price almost never wins, and we will happily help build it — including with numbers that do not favour us.

Safety

Pallet safety, the short version

OSHA 1910.176 covers storage and housekeeping in your building. These are the specifics that actually cause incidents.

  • 01

    Never rack on an unknown rating

    If nobody can produce a racked (edge-support) figure in writing, treat the pallet as unrated and floor stack it. This is the single most common serious incident in warehousing.

  • 02

    Empty stack height

    Keep empty pallet stacks to a sensible, stable height — commonly capped around 15 units or 6 feet by site policy — on level ground, away from exits and sprinkler heads.

  • 03

    Empty pallets are a fire load

    Idle wooden pallets burn fast and hot. Most fire codes limit indoor idle storage and require separation from other combustibles. Outdoor storage needs clearance from buildings.

  • 04

    Never climb a stack

    Obvious, routinely ignored, and the cause of most pallet-related injuries. Use equipment, not a foothold.

  • 05

    Mind protruding fasteners

    Gloves, and reject units with nails standing proud. A nail that tears a case will also tear a hand.

  • 06

    Do not burn treated wood

    Never burn MB-fumigated, painted or chemically treated wood. Untreated offcuts are fine as fuel; everything else goes to a proper stream.

This is general guidance rather than a compliance document. Your local fire code and your own risk assessment govern; we are happy to supply load ratings and treatment records to support yours.

Reference

Standards, bodies and who decides what

Pallets sit under a surprising number of overlapping rules. Here is who writes them and what they actually govern.

ReferenceWho maintains itWhat it governsDoes it bind a used pallet sale?

Oregon EPR (SB 582)Oregon DEQProducer responsibility for packaging; wood is in scope for reportingIncreasingly, yes
FSMA / food safety plansUS FDAPackaging as a food-contact hazard considerationVia your audit, yes

The gap in that list is the interesting part: no authority grades used pallets. That is why a written supplier specification — ours is published here — is the entire quality system in this industry.

Lifecycle

Eleven years in the life of one pallet

A composite built from real Passport records. Individual units vary enormously; the shape does not.

  1. Year 0

    Built

    Douglas fir from a mill inside 180 miles. Seven top boards, five bottom, three stringers, helical nails, 2,800 lb dynamic.

  2. Year 0–2

    Trips 1–4

    Beverage route work. Loaded, racked, unloaded, returned. Colour starts to grey; nothing structural changes.

  3. Year 3

    First inspection failure

    A lead board splits at a nail line. Twenty-minute fix: replacement deck board, re-square, re-stamp. Graded B from here.

  4. Year 3–6

    Trips 5–9

    Nursery and agricultural work, where deck gaps matter more than appearance. Spends two winters partly outdoors.

  5. Year 7

    Companion stringer

    A stringer cracks. A second timber is fitted alongside, spanning the crack. Measurably stiffer than before.

  6. Year 7–10

    Trips 10–13

    Local one-way freight. Tare weight has drifted up a pound from accumulated moisture cycling.

  7. Year 11

    Retired from carrying

    Two bottom boards gone, deck softening. Economic repair ends here. Chalk line through the whole pallet.

  8. Year 11

    Dismantled

    De-nailed board by board. Clear boards to the fabrication shop; structural stock back to the repair bay as donor material.

  9. Year 11

    Recovered

    What is left goes through a magnet and a grinder: mulch, bedding shavings, biomass fuel. The nails go to a scrap partner four miles away.

  10. Year 11+

    Still working

    The best boards are now shelving in a bottle shop, carrying its Passport ID burned into the end grain.

Thirteen trips, two repairs, roughly 143 kg CO₂e avoided against building thirteen new pallets, and nothing landfilled at the end. Look up a real record

Vocabulary

Premium recycled: no plugs, no repairs, tight tolerance, highest published ratings.
HT
Heat treated: 56 °C at the core of the wood for 30 continuous minutes, per ISPM-15.
IPPC mark
The stamp proving treatment: wheat symbol, country code, facility number and treatment code.
Moisture content (MC)
Water in wood expressed as a percentage of its dry weight. Above 25% expect reduced stiffness.
Racked load
What a pallet can carry supported only at its edges in beam racking. The number that matters most.
Static load
What a pallet can hold sitting still on a flat floor. The largest and least useful rating.
Tare weight
The weight of the empty pallet — a real and rarely audited freight cost.

Questions

What people ask about our reference material

What is the minimum order or pickup?

No hard minimum for collection at the yard — come and take four pallets on a Saturday morning if you like. For delivery it is 50 units inside Portland metro and 150 outside it, because the truck has to earn its diesel. Outside our 180-mile fleet radius we quote through partner yards and freight, with the lane itemised.

How fast can this happen?

Standard 48×40 Grade A and B stock: same day for pickup, next day for metro delivery. Block pallets one to three days. Custom builds five to nine business days; engineered runs two to three weeks. Heat treatment is same day for booked batches and 48 hours standard. Written quotes always come back within one business day.

Why is there no phone number anywhere?

Because verbal quotes get remembered differently by different people. Since 2018 every price, date and commitment we make exists in an email you can search and forward. Most customers dislike it for about a month and then prefer it. Everything else happens in person at 3821 NW St Helens Rd, Portland, OR 97210.

Can I inspect before committing?

Please do. Visit the yard by email arrangement — closed-toe boots required, hi-vis provided — or ask for photographs of the actual pool your order would come from. We would rather lose an order than have a customer discover a surprise on their dock.

What documentation comes with it?

A written quote, a signed count sheet by grade, a weight ticket where material is weighed, heat-treatment certificates for treated batches (archived seven years), and a monthly diversion certificate for anything we collect for recycling — measured pounds kept out of landfill, which is the figure your ESG report actually needs.

What will you refuse to do?

Take methyl-bromide fumigated, chemically contaminated or fire-damaged wood. Buy marked rental-pool pallets, which belong to their operator. Promise same-day delivery outside the metro. Or quote a grade we do not think will survive your handling — we will specify downward and explain why.
