Green Curtain
A "green curtain" refers to a fabric or material used to obscure or conceal, most commonly associated with theatrical productions, film and video, and increasingly, in home video conferencing and content creation. Its function is to provide a uniform, digitally removable background, facilitating the insertion of virtual backdrops.
Material
Green curtains are typically made from chroma key fabric, a specific type of material designed for ease of digital keying. Common fabrics include:
- Muslin: Affordable and widely available, but can be prone to wrinkles and less opaque.
- Velvet: Offers a richer, less reflective surface, providing higher quality keying results but is more expensive.
- Seamless Paper: A cost-effective option for temporary setups, but easily damaged.
- Polyester/Cotton Blends: A balance of affordability and durability.
The key characteristic is the specific shade of green (typically a brighter, more saturated hue – often referred to as Chroma Key Green). This color is chosen because it is less common in skin tones and clothing, minimizing spill and making removal easier.
Purpose
The primary purpose of a green curtain is to enable chroma keying (also known as green screen technology). This process involves digitally isolating the green background and replacing it with another image or video.
Function
The function relies on the principle of color difference. Video editing software identifies all pixels within the specified green color range and renders them transparent, allowing the desired background to be overlaid.
Key factors for optimal function:
- Even Illumination: Consistent lighting across the entire curtain surface is crucial to avoid shadows and inconsistencies during keying.
- Wrinkle-Free Surface: Wrinkles create variations in color and shadow, making clean removal difficult.
- Distance from Subject: Maintaining sufficient distance between the subject and the curtain minimizes green spill (green reflections on the subject).
Usage Scenarios
- Film & Television: Creating fantastical environments, special effects, and location backdrops without the cost of physical sets or location shooting.
- Broadcast News: Displaying graphics, maps, and other visual information behind news anchors.
- Video Games: Motion capture and character animation.
- Virtual Meetings & Streaming: Replacing home backgrounds with professional or themed environments.
- Photography: Creating composite images and special effects.
Common Types/Configurations
- Standalone Curtain: A single fabric panel hung from a support system.
- Green Screen Backdrop Kits: Include the curtain, a support stand, and often lighting equipment.
- Pop-Up Green Screens: Collapsible, portable options for quick and easy setup.
- Corner Green Screens: Designed to fit into corners of rooms, maximizing space.
- Green Screen Paint: An alternative to fabric, allowing for permanent or semi-permanent green screen backgrounds.
The declared goods are identified as “green curtain”. Based on the provided information, the classification depends on the material composition of the curtain. Here's a breakdown of potential HS codes:
- 6303910010: This code covers curtains (including drapes) and interior blinds; curtain or bed valances, specifically those of cotton. The total tax rate is 47.8%, comprised of a 10.3% base tariff and a 7.5% additional tariff, increasing to 30% after April 2, 2025. This applies to window curtains and valances.
- 6303922010: This code applies to curtains (including drapes) and interior blinds; curtain or bed valances, specifically those of synthetic fibers. The total tax rate is 48.8%, consisting of an 11.3% base tariff and a 7.5% additional tariff, rising to 30% after April 2, 2025. This also covers window curtains and valances.
Important Considerations:
The applicable tax rate will change after April 2, 2025, with the additional tariff increasing from 7.5% to 30% for both HS codes. Therefore, the timing of import is a factor to consider.
To determine the correct HS code, it is crucial to confirm the material composition of the “green curtain”. If the curtain is made of cotton, use 6303910010. If it is made of synthetic fibers, use 6303922010.
