Darkroom Enlarging Paper Substrate Roll
Uncoated roll paper, 100 g/m² with mechanical pulp fibers >10%, engineered for resin-coated or baryta layers in darkroom enlarging papers for professional photo labs. Falls under HTS 4802.61.50.00 as it's the unsensitized basic paper expressly for photographic sensitization, ensuring high whiteness and minimal curl post-emulsion.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically for photographic use
The .50.00 subheading requires photo sensitization purpose; general graphic purpose uncoated mechanical roll paper goes to .90.00.
If kraftliner grade >115 g/m² with Mullen strength
Meeting kraftliner specs for linerboard in boxes reclassifies to 4804, as packaging paper takes precedence over graphic end-use.
If cut to size sheets with registers or perforations
Chapter notes exclude cut sheets from 4820 only if not for graphic use; perforated photo register paper might shift there.

Import Tips & Compliance
• Label shipments clearly as 'basic paper for photographic sensitization' to guide CBP classification; retain mill certificates for fiber analysis; avoid bulk packaging that mimics printing stock to prevent duty disputes
