In July 2021, the U.S. Division of Commerce Worldwide Commerce Administration levied a mixed 221.37% tariff and countervailing obligation for 5 years towards the Chinese language container chassis producer CIMC Autos Group. The ruling successfully blocks CIMC from dumping new, low-cost chassis and chassis elements into the U.S., in favor of defending home chassis producers. 

A gaggle of 5 U.S. chassis OEMs, calling themselves the Coalition of American Chassis Producers (CACM), had petitioned the Worldwide Commerce Fee for aid to permit for truthful competitors within the face of CIMC’s market dominance. On the time, CIMC had a market share of over 75% of all marine and home container chassis gross sales within the U.S. Its largest-volume yr was 2018 with over 45,000 chassis imported and offered.

For the reason that ITC resolution, a mixture of insufficient North American chassis manufacturing capability and elevated cyclical demand has created a brand new chassis manufacturing vacuum that different producers are hopeful of filling. Whereas the CACM OEMs promised to extend their output to satisfy demand in response to the protecting ruling, their means to ramp up manufacturing has been hampered by present part, materials and labor shortages. The result’s that new chassis suppliers have been bobbing up, each domestically and internationally, in an effort to place themselves for a share of the projected 80,000-unit annual demand in 2023 and past.

Inquiries to Ask When Shopping for from a New Intermodal Chassis Supplier

Questions that any chassis purchaser ought to reply for themselves earlier than shopping for from a brand new provider embody not solely pricing and availability of the product, but additionally guarantee phrases, monetary sustainability, comparable expertise, regulatory compliance, and so on. A few of these new chassis OEM entrants have expertise constructing freeway trailers for North America, however some have a extra restricted understanding of the required regulatory necessities for getting into the market.

Earlier than placing container chassis (or different trailers) on the roads of the U.S., Canada or Mexico, there are variety of vital security, certification and testing standards that have to be met by the supplier, such because the Nationwide Freeway Visitors Security Administration’s Federal Motor Car Security Requirements, in addition to from requirements organizations such because the American Nationwide Requirements Institute, the Truck Trailer Producers Affiliation, the Society of Automotive Engineers, and the Affiliation of American Railroads.

“Does this new OEM chassis meet all relevant certifications and rules?” is a query usually over-looked by consumers or taken without any consideration.  In any case, a lot of the high-level rules are based mostly on the producer’s self-certification of compliance… “Belief us. We learn the regs and you’re good to go!” (Be aware to reader: Caveat emptor…Let the Purchaser Beware).

Only some exceptions exist for the self-certification allowances. Essentially the most complete of those is the AAR (Affiliation of American Railroads) testing necessities for all intermodal autos. The AAR has a long-standing set of rigorous bodily testing necessities for any trailer/chassis that interfaces with North American rail service ,as chassis usually do. As such, container chassis of every kind, marine and home, fall throughout the purview of the AAR testing necessities. Any trailer or chassis which may ever cross over onto North American rail property wants to satisfy or exceed the AAR testing necessities or face big legal responsibility penalties within the occasion of failure or accident.

Potential Legal responsibility for Not Asking About Chassis Requirements

By affiliation with this rail trade requirement, the potential legal responsibility concern extends into all different operational circumstances for intermodal tools, whether or not it is freeway operation, port operation, or simply sitting in a yard or by the aspect of the street awaiting service. Merely put, AAR testing is the “excessive bar” that each chassis model and mannequin should match.

To whom does this legal responsibility publicity prolong aside from the OEM? It’s America, in any case…so, everybody! The leasing firm that buys them, the provider that operates them, the vendor that offered them. With nuclear legal responsibility verdicts commonplace in freight transportation, it is a large deal. You probably have any cash, juries wish to give it to the plaintiff. In case your chassis brought about a rail derailment with hazmat points or whether it is implicated within the horrific lack of life in a freeway crash, anticipate the worst potential judgement and settlement consequence.

To assist defend your self from this extreme legal responsibility publicity is ensure that the chassis you’re shopping for comply in full with all regulatory necessities and, particularly, the AAR prescribed testing standards.

I’m assured that many “authorized beagles” (of which I’m not one) will contest my evaluation, however why take the chance? The AAR assessments are complete and exhaustive concerning structural tolerance and integrity. Don’t all of us need that, anyway?

Compliance with the testing standards laid out in AAR M-931 for intermodal autos is neither easy nor straightforward to fulfill. They require in depth bodily testing of a full automobile, with most of the assessments requiring a whole bunch or 1000’s of repeated cycles. Pc Aided Engineering (CAE) and Finite Ingredient Evaluation (FEA) calculated outcomes are not an appropriate various to the bodily product testing prescribed by M-931. 

Moreover, whereas solely self-certification of the AAR testing is technically required, OEMs which were constructing container chassis for North America for years have historically licensed their bodily check outcomes by contracting with a reputable, certified, unbiased engineering consultancy to supervise the testing and confirm the outcomes.

If a producer assessments and validates its chassis to AAR requirements utilizing solely its personal evaluation and a few video tapes to show satisfaction of the outcomes, in a courtroom case, you might be requested why you did not do a greater job of constructing positive you had been shopping for secure tools — in entrance of a jury that’s probably sympathetic to the defendant.

In conclusion, is the chassis you’re shopping for 100% compliant with all governmental rules in addition to AAR requirements? Ask your chassis supplier, and ensure they’ve actual proof do assist that declare.
