Baryta Coated Photographic Base Paper A4
This is a baryta-coated paper in A4 sheets (210x297 mm), weighing 120 g/m², designed as basic paper to be sensitized for analog black and white photography. It meets HTS 4810.14.11.20 criteria: kaolin-coated with baryta, one side ≤435 mm and other ≤297 mm unfolded, one side >360 mm and other >150 mm, ≤150 g/m², for photographic sensitization. The baryta layer provides a smooth, reflective surface ideal for emulsion coating.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If weighing over 150 g/m²
Exceeding 150 g/m² weight moves it out of the 'not more than 150 g/m²' subheading into other printing paper categories.
If pre-sensitized with photographic emulsion
Once sensitized for photography, it becomes 'photographic paper' in Chapter 37, not basic uncoated paper.
If containing >10% mechanical/chemi-mechanical fibers
Heading 4810 excludes paper with more than 10% mechanical fibers; such content shifts to subheading 4810.19.

Import Tips & Compliance
• Verify baryta (barium sulfate) coating and weight ≤150 g/m² via lab testing; provide mill test certificates for Customs
• Confirm sheet dimensions qualify (one side >360 mm, other >150 mm, max 435x297 mm unfolded) to avoid reclassification
• Avoid common pitfall of printing motifs that dominate use, which shifts to Chapter 49; keep paper unsensitized and unprinted
