Understanding the Science & Laboratory Category
The Science & Laboratory category, designated by ID 1624, sits within the Business & Industrial vertical under the parent category of Business & Industrial. This specific classification is designed to house professional-grade, academic, and hobbyist equipment and supplies used in controlled environments for research, analysis, and experimentation.
What Belongs in Science & Laboratory
This category is intended for goods that are fundamentally designed for scientific utility. Examples of products found in this category in the US market include various laboratory chemicals, such as reagents like sodium thiosulfate, ammonium hydroxide, and acetic acid solutions. It also includes essential lab glassware and containers, such as low-form beakers, polypropylene funnels, and specialized formalin-filled containers used for specimen preservation. Furthermore, this category captures advanced laboratory apparatus, including magnetic stirrers with hot plates, benchtop centrifuges, and jacketed glass reactor systems. Educational and diagnostic tools also fit here, such as science-based dissection kits for student learning and urine collection cups with integrated transfer devices used in clinical or research settings.
What Does Not Belong Here
It is common for Google Shopping results to be noisy, but products that belong in adjacent or specialized categories should not be placed in Science & Laboratory. For instance, items related to professional medical diagnosis that are not specifically lab-oriented should be placed under the Medical category. Equipment primarily designed for large-scale agricultural operations belongs in Agriculture, whereas heavy industrial equipment should be categorized under Heavy Machinery. Janitorial supplies, such as cleaning carts or maintenance equipment, fall under the Janitorial Carts & Caddies category. If you are selling protective gear for lab workers, ensure those are mapped to Work Safety Protective Gear rather than the lab category itself, as the former is designed to trigger specific safety-related policy filters in Merchant Center. Additionally, items related to dentistry, such as specialized tools or chairs, must be assigned to the Dentistry category.
When to Choose a Subcategory
Because Science & Laboratory (ID 1624) is a broad category, you should always aim for the most specific subcategory available in the Google product taxonomy if your product fits one. You should use Laboratory Chemicals when listing reagents or biochemicals. Use Laboratory Supplies for consumables such as stir bars, specific plasticware, or storage containers. Laboratory Equipment should be reserved for larger, durable apparatus like the centrifuges or reactors mentioned previously. If you are selling specialized biological items, utilize Laboratory Specimens or Dissection Kits. Using these granular subcategories helps ensure your products appear in the correct filtered search results, which increases the likelihood of reaching qualified buyers who are searching for specific scientific materials rather than general lab equipment.
How to Configure Your Feed
To implement this in your Merchant Center feed, you must use the google_product_category attribute. You have two options for the input value: the numeric ID or the full path. The numeric ID (1624) is generally preferred because it is language-independent and less prone to errors during system migrations. Alternatively, you may provide the full string: Business & Industrial > Science & Laboratory. Note that while this attribute is optional, it is highly recommended to include it. If you choose not to provide it, Google will attempt to auto-categorize your products; however, automated systems often err on the side of generality, which can hurt your click-through rates. Remember that the product_type attribute is entirely separate and should be used for your own internal organizational taxonomy, as it does not replace the required google_product_category. Proper classification does not change who sees your ad, but it does define which requirements Google imposes on your feed data, ensuring your products remain compliant with category-specific policies.
