Custom crating is the difference between machinery that arrives ready to install and machinery that arrives with a bent flange and an insurance claim. For Miami-area exporters moving high-value cargo through the ports and MIA, the crate is the last line of defense against handling stress, humidity, and shifting during long ocean voyages.
ISPM-15 — The Non-Negotiable Baseline
Any wooden packaging material used in international shipments must comply with ISPM-15: heat treated (HT) or fumigated, and stamped with the IPPC mark plus country and treatment code. Non-compliant crates get held, re-exported, or destroyed at destination — customs authorities worldwide enforce this consistently. Miami exporters need a crating supplier whose materials are ISPM-15 stamped at the mill and traceable by lot.
When to Choose a Crate vs. a Skid vs. a Box
Skids work for stable, weather-tolerant cargo that just needs a base for forklift handling. Boxes (fully enclosed on all sides) protect against handling contact but not against sustained compression from stacking. Crates — engineered wood frames with bracing — handle the compression, impact, and shifting loads of an ocean voyage. For anything above roughly 500 lbs of value density, a crate is usually the right answer.
Materials Beyond Wood
Plywood for panel skin — 3/8″ to 1/2″ for most industrial crates. Dimensional lumber for framing — grade and moisture content matter. Foam and blocking for interior support — high-density polyethylene foam holds shape and doesn’t shed particles. Vapor barrier for humidity-sensitive cargo — foil laminate bags with desiccant packs. Steel banding for external containment.
Engineering for the Actual Voyage
A crate designed for a truck ride from Doral to Fort Lauderdale looks different from one designed for a 30-day ocean voyage to Chile. The ocean crate needs additional cross-bracing for roll and pitch loads, vapor protection for salt-air exposure, and often internal cushioning to isolate delicate instruments from vibration.
Documentation and Marking
Export crates need clear marking: shipper, consignee, gross and net weight, dimensions, handling symbols (fragile, this side up, keep dry), and identifying case numbers. For hazardous or controlled cargo, additional marking may apply. A crate that shows up at a foreign port without clear markings is a crate that gets set aside.
The Miami Advantage
Miami’s exporter community is deeply international — LATAM, Caribbean, Europe. A crating operation embedded in South Florida’s freight ecosystem can move from build to load in hours, not days. That matters when a customer is trying to hit a vessel cutoff.
Bottom Line
Custom crating is where good freight programs stop losing money to damage claims. Go-Freight’s crating operation builds to ISPM-15, engineers for actual voyage stresses, and coordinates directly with our own drayage, warehousing, and export services — so cargo moves from build to vessel without a handoff gap.
