Chemicals & additives

Chemical freight on the Cargado marketplace is broader — and tamer — than the word suggests. The bulk of the category is industrial additives, absorbent polymers, calcium carbonate, graphite rods, paints, lubricants, and mineral products, and posting descriptions go out of their way to say so: non-hazmat chemicals, lubricant non-haz, and water-based paint are recurring phrasings. Shippers know that clarity about hazard status is the first thing a carrier checks.

Where chemical freight moves

Houston, the petrochemical capital of the Gulf, is the leading U.S. origin in the data, sending chemicals, resins, and absorbent polymers south — flows that cross overwhelmingly at Laredo. Monterrey generates steady industrial-chemical volume including graphite rods, Nogales in Sonora posts calcium carbonate at scale, and the Mexico City industrial belt ships liquid product in totes, IBCs, and drums. Crop-protection chemicals and packaged fertilizer round out the agricultural edge of the category.

Non-hazmat: the default case

• Dry van rules the category. Bagged powders, palletized drums, totes, and IBCs move in standard dry vans with ordinary securement.
• Bulk liquids are the exception, riding tankers — pipas in Mexican fleet terminology — which are a specialized capacity pool.
• Say non-hazmat explicitly. The single best thing a broker can do on a chemical posting is state the hazard status. The data shows experienced shippers do exactly that.

When it is hazmat

Regulated chemicals change the job completely. Cross-border hazmat requires the UN number and proper shipping name up front — Mexican carriers need them for their own permits and will not quote blind — plus placarding, driver certification, and compatible insurance. Certain crossings handle hazmat traffic better than others, so the crossing becomes part of the plan. None of this is exotic for carriers who run chemicals regularly, but it cannot be discovered after booking: a posting that omits the UN number will sit unbid or get repriced at the dock.

Weight is the other quiet constraint in this category: dense mineral products like calcium carbonate gross out a trailer long before it cubes out, so accurate per-pallet weights belong on every posting. The Mexico 101 guides cover crossing mechanics and documentation, and the lanes pages show corridor-level activity for chemical-heavy markets.
