Contamination Prevention Guidelines
All groups with an interest in cotton's end use are responsible for ensuring U.S. cotton maintains its reputation as a source of clean fiber.

Round Module System
Volume VI of the National Cotton Ginners Association's Safety Series is a 17-minute training video that includes information about module system safety, round module handling and wrap removal with a strong emphasis on safety and contamination prevention.

7 Steps to a Contamination-Free Cotton Harvest
This AgWeb article, which lists seven best practices for keeping cotton "contamination free," notes that a simple plastic bag actually can be a cotton farmer's No. 1 enemy.

Lint Contamination Prevention Always a Priority
This Ginning Marketplace column that appeared in the August 2015 edition of Cotton Farming magazine reminds us why "... U.S. cotton merits a market premium. ... 1) we have a quality product and 2) it is relatively free of contamination."

Attention to Detail
In Cotton Farming magazine's August 2014 column the National Cotton Council addresses the latest International Textile Manufacturers Federation's Cotton Contamination Survey findings and reminds industry members to make contamination prevention a day-to-day priority.

Cotton Contamination Prevention Alert -- Striving for Zero Tolerance
Cotton producers, ginners, warehouses and their employees are encouraged to pay particular attention to contamination prevention this harvest season. The goal is to keep any and all foreign materials out of seed cotton and baled lint.

Pursuing Zero Tolerance
In Cotton Farming magazine's August 2013 Cotton's Agenda column, the National Cotton Council urges producers, ginners, warehouses and their employees to be proactive in preventing lint contamination.

Opinions Vary On 'Ground' Cotton
Cotton Farming magazine's Western Region Edition (October 2013) noted that "...cotton roods gather a great deal of cotton, they also pick up almost everything else they encounter in the field – dirt, rocks, tarp, plastic bags, sticks, etc. ..."

Prevent Lint Contamination
Protecting cotton fiber from contaminants can help preserve markets. This publication offers steps that can be taken to prevent problems with materials that can contaminate seed cotton and lint and result in blemished finished goods.

Contamination Free Cotton: Keep It Clean and Pure
"Keep It Clean and Pure" powerpoint presentations with both English and Spanish narrations are now available online!

Cotton Module Transportation Calculator
How far can module trucks travel to retrieve modules in order to increase gin machinery utilization before transportation costs negatively impact ginning costs?

Recently Updated! Bale Marker Evaluation Study
Questions continue to be asked about module marking materials. The message to producers and ginners remains the same: any material described as permanent should not be used as a module or a bale marker.

Recommendations for Handling Seed cotton Exposed To Excessive Rainfall
Widespread extended rainy and wet conditions periodically impact the U.S. cotton crop. Almost every year, some growing areas experience significant yield and quality losses due to inclement weather. Wet weather negatively impacts lint color and seed quality.

NCC Bale Moisture Fact Sheet
Because NCC policy recommends moisture levels in cotton bales at the gin not exceed 7.5%, the NCC's Quality Task Force urges diligence be exercised to minimize the possibility of fiber quality deterioration due to excessive water and concentrated wet spots; this is a special concern with gins that use liquid spraying systems.

Just Build It: Seed-Cotton Storage & Handling in Modules
Since modules were introduced in 1972, their use has steadily increased. Today nearly all seed-cotton is stored in modules prior to ginning. Handling and storing seed-cotton in modules clearly benefits both growers and ginners by de-coupling the harvesting from ginning processes.

Just Tarp It: Selecting a Module Cover
Dimensions and characteristics of tarpaulins are important factors when selecting a module covers. Many varieties of cover materials and features available. Guidelines for choosing covers are presented.


The handling of round modules presents some unique challenges for growers and ginners. Some of those challenges are addressed in John Deere's round module handling and ginning preparation recommendations.

Cotton harvest systems publications from Cotton Incorporated covering:
1)  Spindle-type cotton harvesters,
2)  Stripper-type harvesters,
3)  Handling and storage of seed cotton, and
4)  Economic decision aids (cotton harvest equipment investment analysis)

National Cotton Council of America (NCC) policy directs the NCC to actively pursue the elimination of lint contamination from all sources and work with U.S. textile manufacturers to develop a Cotton Contamination Incident Reporting system.
