Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into plates or sheets
NBR converted to plates, sheets, or profiles falls under heading 4008, not primary latex.
If it's chloroprene (neoprene) rubber instead of NBR
Different synthetic rubber types have separate subheadings within 4002.
If polymerized beyond rubber definition
Polymers not meeting vulcanization/elongation tests per note 2(b) classify as plastics.

Import Tips & Compliance
• Ensure shipment manifests specify 'latex for foaming' to distinguish from finished foam articles
• Test for emulsifier content; excess may violate primary form note allowances
• Obtain supplier vulcanization test certifications to confirm synthetic rubber eligibility
