Frequently asked questions
What is AHECC chapter 31?
Fertilisers is a chapter within AHECC section VI. It sits directly above the export statistical item codes used in declarations.
Is the chapter code enough for an export declaration?
Usually not. Export declarations typically require the final 8-digit export statistical item code, not just the chapter heading.
Why are item codes listed directly on this page?
The chapter page is the shortest path from category browsing to the final export code. Listing the end codes here makes the last step explicit.
