Proposed Change to the National Motor Freight Classification

May 15, 2013

The Commodity Classification Standards Board will have a public meeting on Monday, June 3, 2013 to consider changes to a standard that may impact you. The concern involves the transport of corrugated sheets by way of common carrier motor freight. If you ship sheets by a mode that this not owned by the combiner or is a contract carrier, this may be of interest to you. Below is a summary from Dave Carlson at FBA.

“The NMFTA/CCSB material that I have looked at is Docket 2013-2 for the June 3, 2013 CCSB meeting at Alexandria, VA. The only item of interest to the corrugated industry is Subject 14, which deals with changes in the classifications for shipping corrugated sheets. This is the third classification revision involving shipping corrugated products over the past 7 years. KD corrugated was changed in 2006, corrugated cut shapes (D/C), molded pulp, corner posts changed in 2011, and now we have sheets. The proposed classifications for sheets are not materially different than the classifications now in effect for the other two types of corrugated products, so I don’t think the industry has much of a leg to stand on a far as challenging the proposal. The end result will most likely be an opportunity for modest increases by motor carriers to transport corrugated sheets. While the classifications are standard for truckers, the rates they charge must be independently set, per antitrust regulations. However, the effects will be limited because the huge majority of sheets shipped in the U.S. are handled by contract carriers with rates established in the contracts between box plants and the truck lines. Another factor is that the classifications apply to interstate carriers with LTL freight. “

I have provided the Subject 14 material to our Technical Committee and asked for comments from them.”

EB Doublewall Sample Size for ECT Test

April 29, 2013

Linda asked:

I read that for an EB flute combination a different sample size may be required. In order to get correct ECT, what size do I need to cut my samples?

TAPPI Test Method T-839 calls for all flutes and doublewall and triplewall combination samples to measure 2 inches by 2 inches.

Combustibility of corrugated paper dust

April 24, 2013

Mike asks:

Can you tell me if there is an industry standard on “combustibility of paper dust for corrugated” and if so what that standard might be.

We have been hearing a lot about people needing combustion proof vacuum cleaners to clean out electrical cabinets and so on up and down the corrugator. The question came up as too exactly how combustible corrugated paper dust is.

The simple answer is that it is combustible enough that you should use precautions to protect against spark or open flames when high concentrations of paper dust are in the air or in a confined space, such as a vacuum cleaner canister.

Over the last several years there have been public meetings with OSHA and the National Fibre Prevention Association about this subject. There is information about this in NAPA 68 and the Federal Register under 29 CFR Part 1910. While it came to light because of explosions in sugar refineries, metal processing plants, food processing operations and coal fired power plants it has spilled over into cellulose dust. NAPA writes the requirements and OSHA enforces the standard. It is still evolving, and OSHA may enforce the standard unequally.

As far as I know it is still under a National Emphasis Program. This may be mandated by your insurance agency, and NAPA is to be treated as a legal code.

I would start to move in this direction, as it is just a matter of time before enforcement intensifies even with sequestration. Let me hear back from you if you need some additional documentation. You can also talk with the folks at Ohio Blow Pipe.

Clean Room Friendly Paperboard?

April 24, 2013

Charlie asks:

Are you aware of any corrugated material or other packaging material that is approved for packaging of medical devices? Basically they have products in a clean room, they use a poly bag over the box and inside the box currently…are you aware of something that is “clean room” friendly?

Well Charlie… When we think of corrugated, or most any paperboard product, “clean room” friendly is probably one of the last thoughts that cross our minds. Even the slightest amount of dust created by handling these products would be unacceptable in a true “clean room” application.

However, corrugated, while not necessarily approved for medical devices, isn’t disapproved either. Corrugated is approved by the FDA for indirect food contact, but that is certainly different than a medical device that may potentially be used, or placed inside the human body. The use of an inside poly bag and proper handling procedures should exclude any direct contact.

Some of the issues we often encounter are the need for pH neutral packaging for devices that have silver components. I believe my last ten cell phones where packaged in corrugated!!! However, even though some folks – especially teenage girls – seem to have these surgically attached, they certainly are not required to meet the same sterility standards as a medical device.

As far as clean room ready, corrugated needs to be stored in cool dry places where there is little or no chance of invasion by plants or animals, i.e. mold, mildew, fungus, insects and the odd stray varmint. However, you’ll still most likely require some type of sterile protective barrier inside, and depending on the application possible outside, of any type of paperboard container you may use.

I’m not aware of any particular paperboard product that is marketed as clean room ready. Let’s toss this one out to the masses and see if anyone else has any comments.
