What GTIN would you use under this co-marketing scenario?

I saw this conversation on Linked In and felt that it was worthy to repost here for preserving...
Here’s the scenario:

A large multi-national manufactures and packages pharmaceutical finished goods. One presentation of these finished goods are sold in the US through a Partner (co-marketing arrangement). The Artwork and GTIN (NDC) of the product is that of the Partner. However the manufacturing authorization holder (MAH) is the large multi-national brand owner. With Serialization according to the DSCSA, should the GTIN remain that of the Partner? Or, would it need to revert to the MAH?
My belief is that it would not change – remain that of the Partner. Curious if you have come across this and if so, what approach you would take. 

Why Does ANVISA Embrace GS1 Standards, Except The Serial Number? - By Dirk Rodgers

Dirk Rodgers of RxTrace.com has written another great article on ANVISA... Read below for an excerpt  or read the full article here. Serialization is a challenge and with this interpretation from the Brazilian authorities it certainly complicates matters for manufacturers if their goods land up in Brazil...

"In Brazil, the National Agency of Sanitary Surveillance (ANVISA) has built their pharma serialization regulation around GS1 standards. They embrace the GS1 Datamatrix and GS1-128, both encoded with GS1 Application Identifiers (AI) and using GS1 Human Readable Interpretation (HRI) (see my previous essay, “The ANVISA Unique Medicine Identifier (IUM) on Drug Packages”, for my thoughts on HRI), the GS1 Global Trade Item Number (GTIN) and the GS1 Serial Shipping Container Code (SSCC) to be specific. But there is one GS1 standard they steer clear of: the GS1 serial number. Why is that?

The ANVISA Unique Medicine Identifier (IUM) on Drug Packages - Dirk Rodgers

Last week Dirk wrote about the DSCSA Product Identifier on Drug Packages in the United States.  Last month he wrote about shipping container/transport package identification under the Brazil National Medicine Control System (SNCM) (see “ANVISA And The SSCC Controversy”).  In this article Dirk takes a look at drug package identifiers under the SNCM as regulated by the National Agency of Sanitary Surveillance (ANVISA).  Dirk is a member of the GS1 Healthcare group - Contact GS1 Healthcare for more information.

An excerpt from Dirk's article:

"Under the SNCM, manufacturers must apply a Unique Medicine Identifier (IUM) to all drug packages imported or sold into the Brazilian supply chain and trace them through the supply chain by December 11, 2016.  By December 11 of 2015, manufacturers must apply the IUM to the packages of at least three lots of drugs and trace them to the dispensing points.  And you thought compliance with the DSCSA was going to be hard to achieve!

Pharma Serialization Update - April

Bill Fletcher highlights a few key deadlines looming for Pharma Serialization:

1. The FDA enforcement discretion not to enforce the transaction document aspects of the Drug Supply Chain Security Act (DSCSA) ends May 1. Companies who may have chosen to spend more time working out kinks in their transaction document (TD) may be running out of time.  
2. There is controversy with the way shipper cases are tracked in Brazil.
3. Companies selling into Brazil will now need to collect traceability data from 3 LOTs by December of this year. 
4. Chinese traceability is fully effective this December.  
5. New requirements in India for primary packages are creating very onerous designs on manufacturers
6. EU delegated acts for Falsified Medicines is expected in the next couple of months. Encoding will include GTIN, country reimbursement code, LOT expiration date and serial number in human readable and encoded in a GS1 DataMatrix symbol

ANVISA And The SSCC Controversy - By Dirk Rodgers

GS1’s Serial Shipping Container Code, or SSCC, has been around a long time, but the logistics identifier has recently taken center-stage in a number of controversies related to meeting several country-specific pharma traceability regulations. I’ll cover these controversies in multiple essays—in this one, Brazil. 
This controversy started when ANVISA, the pharma regulator in Brazil, indicated in their regulations that they expected companies to mark every “transport package” entering their supply chain with a unique identification code so that each serialized unit inside can be associated with it (the aggregation requirement).
The problem is, a homogeneous case of product can be both a “standard grouping” of the product and a transport package. GS1 recommends that “standard groupings” of product be marked with its own GS1 Global Trade Item Number, or GTIN. Read the full article at RxTrace.com - Author Dirk Rodgers
