Export Crating Chicago: Requirements and Process

Quick Answer: Export crating in Chicago means building export-grade wooden crates that meet ISPM 15 where the destination country requires it: solid wood either heat treated to a 56°C core for 30 minutes or fumigated with methyl bromide, and stamped with an IPPC mark. Finished crates fly from O'Hare or move by rail and truck to Houston, New York/New Jersey, Savannah and Montreal.

Chicago is the usual export gateway for shippers in Illinois, Indiana, Wisconsin, Michigan, Ohio, Minnesota, Iowa, North Dakota and South Dakota. Our warehouse in Chicago receives, stores, packs and consolidates that cargo before it leaves by air from O'Hare or by rail and truck to the coast.

What is export crating and how is it different from regular crating?

Quick Answer: Export crating is packing built for international transit: ISPM 15 compliant wood, engineered load paths, moisture barriers and stenciled markings. Domestic crating protects cargo for a few days on one truck. An export crate must survive forklift handling at four ports, container sweat, and customs inspection abroad.

The difference is the number of hands on the box. A domestic crate from Chicago to Dallas gets loaded once and unloaded once. An export crate from Chicago to Callao gets handled four to eight times before the consignee sees it.

Count the events on a typical ocean move. Plant forklift, cross-dock in Chicago, container freight station stuffing, vessel loading, vessel discharge, port yard move, drayage, final delivery. Each one is a chance to drop, crush or puncture.

Domestic crates can use whatever untreated lumber the shop has on hand. Export crates cannot, if any solid wood touches the build. That single rule separates the two trades.

Customs officers abroad also open crates. DIAN in Colombia and SUNAT in Peru both run physical inspections on machinery entries. A nailed-shut lid gets pried apart and badly reclosed. Screw fasteners and a reclosable lid let an inspector open and reseal your crate without destroying it.

Do I need ISPM 15 heat treated wood to ship a crate overseas?

Quick Answer: Only if the importing country requires it, as many do. ISPM 15 is the international phytosanitary standard for wood packaging material, enforced by each importing country's plant-health authority. Solid wood over 6mm must be debarked and either heated to a 56°C core for 30 minutes or fumigated with methyl bromide, then stamped with an IPPC mark. Non-compliant crates get fumigated, re-exported or destroyed at your cost.

ISPM 15 stands for International Standard for Phytosanitary Measures No. 15. It exists to stop wood-boring pests from crossing borders inside pallets and crates. Nearly every trading nation enforces it.

The enforcers you will meet on the USA–Latin America lane are specific. CBP and USDA APHIS police inbound wood into the United States. CBSA does the same in Canada. On the import side, the destination country's plant-health or customs authority checks the stamp.

How to read the HT stamp

The IPPC mark is not decorative. It carries four pieces of data, and your crate builder must apply it correctly.

• The IPPC wheat symbol — the standardized ear-of-wheat logo on the left side of the mark
• Two-letter country code — "US" for lumber treated in the United States, "CA" for Canada
• Producer or facility number — the unique registration number of the treatment facility
• Treatment code — HT for heat treatment, MB for methyl bromide, DH for dielectric heating

Under ISPM 15 the mark should be visible while the packaging is in use, preferably on at least two opposite sides of the crate or pallet; a composite unit is marked as a single unit. One stamp hidden under a skid does not satisfy an inspector at Cartagena.

Is plywood exempt from ISPM 15?

Yes. Plywood, OSB, particleboard, veneer and corrugated fiberboard are exempt. Manufacturing already heats, glues and processes these materials, which kills any pest. The regulation targets raw solid wood.

Here is the trap. A plywood box sits on solid-wood skids and uses solid-wood cleats. Those parts are not exempt. Where the importing country requires ISPM 15, they need an IPPC stamp for heat treatment or methyl bromide fumigation, and an inspector will look for it.

The penalty for getting this wrong is not a fine you pay later. It is a port hold today. Per ISPM 15 enforcement practice, the importing authority can order fumigation on arrival, mandatory re-export at the shipper's expense, or destruction. Practice varies by country, so confirm the destination's requirements before shipping.

Which crate style fits your cargo?

Quick Answer: Crate style follows weight, value and handling. Cleated plywood boxes suit machinery and electronics. Open slat crates work for weatherproof steel. Skids carry machines that need only a base and bracing. Knockdown bolted crates ship flat and get reused. Foam-in-place protects irregular, high-value instruments.

Published engineering standards, including ASTM standards for wood boxes and crates and military packaging specifications, guide the design work. Ask which standard applies to your cargo; defense customers will name their packaging specification.

Good crate design starts with the machine, not the lumber. You need the center of gravity, the total weight, the lift points and the forklift pocket spacing. Mark the CG on two faces so the rigger at Puerto Cortés does not guess.

Blocking and bracing carry the load into the skid, never into the side panels. Plywood walls are shear members, not structure. Bolt the machine feet directly to the base, then brace against lateral movement.

For paintings, sculpture, antiques and museum-grade pieces, the build rules change completely — double-wall construction, climate buffering and interior suspension. We cover that in detail in our guide to Moving Antiques and Artwork Internationally: Custom Crating for USA to South America Shipments.

How do you protect a crate from moisture and corrosion at sea?

Quick Answer: Container rain is the main threat on a 20-30 day ocean leg. Machined steel needs VCI film or VCI emitters, a sealed barrier bag, and desiccant units sized for the bag and the transit time. Shrink wrap alone traps humidity and makes corrosion worse.

Container sweat is simple physics. You stuff a box in Chicago in July with warm, humid air inside. The container crosses into cooler Atlantic water off the Carolinas. The air hits dew point, and water condenses on the steel ceiling and rains down on your crate.

A 30-day sailing from New York/New Jersey to Buenos Aires can cycle through that several times. Rust on a machined surface is not cosmetic — it is a rejected delivery.

Desiccant is a calculation, not a guess

Desiccant units are sized from the barrier-bag surface area and the voyage length. A bag with more square footage leaks more vapor and needs more units. A 35-day transit needs more than a 12-day one.

Ask your crating provider to show the calculation in writing. If the answer is "we throw in a few bags," they are guessing. Written desiccant math is also what defends a cargo claim later.

• VCI film and VCI paper release a vapor-phase corrosion inhibitor that plates onto ferrous surfaces
• VCI emitters protect enclosed voids like gearboxes and control cabinets
• Vapor-barrier liner stapled inside the crate panels stops drip water from reaching the load
• Anti-static film plus foam-in-place or suspension packing for electronics, lab instruments and PLC cabinets

Electronics deserve their own treatment plan. Our 2026 packing guide for moving electronics and fragile items internationally walks through anti-static materials, foam densities and screen protection for the USA to Central America lane.

How does your crate leave Chicago — ORD air, rail, or truck to the coast?

Quick Answer: Chicago is an inland gateway with three outbound paths. Air cargo leaves O'Hare (ORD) worldwide. Ocean freight moves by rail or truck to Houston, New York/New Jersey, Savannah, Los Angeles/Long Beach or Montreal for stuffing. Truckload runs direct to Mexico and Canada. The path changes the crate spec.

Chicago serves a wide inland region. Shippers in Illinois, Indiana, Wisconsin, Michigan and Ohio truck their cargo in, usually same-day or next-day. Minnesota, Iowa, North Dakota and South Dakota move longer hauls by truck or by rail into the Chicago ramps.

Our warehouse in Chicago receives, stores, packs and consolidates that cargo. From there the crate takes one of three roads out.

What is a container freight station (CFS)?

A CFS is a facility where LCL cargo is received, stuffed into shared containers, and later deconsolidated at destination. Your crate arrives loose, gets measured and weighed, then loaded alongside other shippers' freight. Bonded CFS warehouses can hold cargo under customs control; non-bonded ones cannot.

Ocean cargo out of Chicago usually drays to a rail ramp first — BNSF Logistics Park in Elwood or UP Global IV in Joliet — then rides to the coastal port. Breakbulk and project pieces can also move through the Illinois International Port District on the lake.

If your ocean leg runs through the Northeast, read our breakdown of international movers in New York and how the NY/NJ gateway works before you fix your cut-off dates.

Why air crates must be lighter

Airlines charge on chargeable weight, which is the greater of actual weight and dimensional weight. The standard air formula is length × width × height in cm ÷ 6000. A bulky crate with light contents pays for air it does not displace.

That is why air crates use thinner plywood, lighter cleats and tighter internal clearances. Ocean crates can afford heavier lumber because the cost driver is cubic meters, not kilos.

Who is responsible for export packaging under Incoterms?

Quick Answer: The Incoterms 2020 rule in your sales contract decides who handles export packing and who pays for it. Check the packing obligations of the rule you agreed, and write the packing specification — including ISPM 15 compliance where the destination requires it — into the contract.

This is where money quietly changes hands. Most disputes over a damaged machine trace back to a packing clause nobody read.

• EXW (Ex Works): the buyer owns loading, export packing and any ISPM 15 failure. A Chicago factory selling EXW has no obligation to build an export crate. Buyers from Bogotá and Lima discover this at the dock.
• FCA and FOB: packing, export clearance and the point where risk shifts depend on the rule and the named place; confirm them in the contract.
• CIF and DAP: the seller buys the main carriage. A packing failure still lands on the seller through the cargo claim, even after risk has transferred.
• DDP (Delivered Duty Paid): the seller takes on obligations in the destination country, including import clearance. It reads well on a quote and exposes first-time exporters to foreign tax registration they never planned for.

What documents and markings must go with a crated export?

Quick Answer: A crated export normally travels with a commercial invoice and a detailed packing list, plus an EEI filing in AES when the value exceeds $2,500 per Schedule B line or the goods need an export license. Markings must match the packing list exactly or customs abroad will hold the shipment.

The packing list is the document customs officers actually use. It must break down crate by crate, not shipment-wide.

• Crate number and "crate 1 of 4" sequencing
• Outer dimensions in cm and inches
• Net and gross weight per crate
• Cubic volume per crate and shipment total
• Contents by line item with the matching Schedule B or HTS code

AES filing and the ITN

Per US Census Bureau Foreign Trade Regulations, you file Electronic Export Information in AES when a single Schedule B line exceeds $2,500 in value, or when the goods need an export license regardless of value. The system returns an Internal Transaction Number. That ITN goes on the bill of lading or air waybill before the carrier will move the cargo.

Destination paperwork for Latin America

• Factura Comercial — the commercial invoice, often required in Spanish
• Certificado de Origen — proof of origin for preferential duty; depending on the trade agreement it may be a certificate of origin or a certification/declaration of origin
• Buyer tax IDs — RUT and NIT in Colombia, RFC in Mexico, RUC in Peru
• Dangerous goods declaration — may apply to lithium batteries inside a machine depending on battery size; under 49 CFR 173.185 small batteries contained in equipment are excepted, so confirm with your forwarder before shipping

Markings are not optional decoration either. Stencil standard handling pictograms: this way up, fragile, sling here, no hooks, keep dry, and the center-of-gravity mark. Add the consignee mark, port of discharge and crate x of y.

Small parcels and courier shipments follow a different documentation path. See our USA to Central America international courier customs requirements and compliance guide for that side of the business. The Bureau of Industry and Security also publishes freight forwarder guidance and best practices on export control screening.

How much does it cost to build an export crate in Chicago?

Quick Answer: Export crating in Chicago is priced by crate volume, lumber and plywood grade, labor hours, and the protection package inside. Weight class, on-site versus in-shop work, rush turnaround and moisture treatment all move the number. The calculator on this page prices your freight from your exact origin in seconds.

No two crate quotes compare cleanly unless you list the drivers. These are the line items that move the price.

• Outer cubic volume — the single biggest driver on both the build and the freight
• Panel thickness and plywood grade — 1/4" for light goods, 1/2" to 3/4" for machinery
• Skid lumber size — 2×4 for light loads, 4×4 or 4×6 for heavy machines
• Fastener type — screws and reclosable hardware cost more than nails, and pay for themselves at inspection
• Internal bracing hours — the labor that actually keeps the machine still
• VCI, desiccant and barrier bag — scaled to voyage length
• Foam-in-place — material plus cure time for irregular shapes
• Marking and documentation — stenciling, IPPC stamping, packing-list preparation

On-site crating adds a crew travel and rigging component. If the machine can be trucked, in-shop crating at our warehouse in Chicago is usually the cheaper path. If it cannot — a bolted-down press, a cleanroom instrument, a McCormick Place exhibit — on-site is the only option.

Plan 3 to 5 business days for a standard machine crate from measurement to finished build. Rush and same-day work prices above standard lead time.

Households and relocations face the same volume math on a smaller scale. Our guide to affordable international moving in 2026 and 12 ways to save money on a household goods shipment applies the same logic to personal effects.

Export crating Chicago: how to choose a provider

Quick Answer: Vet a Chicago export crating provider on four things: a current IPPC heat-treatment certification or a stamped-lumber supply chain, written crate engineering to ASTM standards, in-house freight forwarding, and proof of insurance. Ask for a sample packing list and photographs of a finished crate before you commit.

Run this checklist before you release a machine to anyone.

1. Confirm IPPC stamping authority or a documented HT-stamped lumber supply chain with certificates on file.
2. Ask which standards they design to — ASTM D6251, ASTM D6039, and MIL-STD-2073 for aerospace and defense work.
3. Request the written desiccant calculation for your voyage length, not a verbal estimate.
4. Check whether they move the freight too, or leave you coordinating drayage, CFS cut-offs and the AES filing alone.
5. Verify on-site capability at Chicagoland plants, labs, data centers and McCormick Place — rigging, machine skidding, millwright coordination.
6. Get lead times in writing, tied to the real port cut-off date.

One point on insurance that experienced exporters learn the hard way. Cargo claims get denied for inadequate packing more often than for any other reason. A documented crate specification plus a photo file of the build is the evidence that wins the claim. A crate with no paperwork behind it is an uninsured crate in practice.

With thousands of shipments processed across the USA–Latin America corridor, we build the crate, file the paperwork and move the freight under one file number. That removes the handoff where most export problems start. Use the calculator on this page to price ocean FCL, LCL and air from Chicago to Cartagena, Callao, Veracruz, Santos, Caucedo or anywhere else in the region — it prices your exact origin in seconds, with no email and no follow-up calls. For breakbulk, oversized machinery or dangerous goods, the same form sends your specifications straight to a project cargo specialist.
