NSF 61 fittings are products tested and certified to a US standard for drinking water components, and WRAS approval is the UK scheme for water fittings. Neither is a general quality mark. Each confirms that a specific product, made at a specific site, does not contaminate drinking water.
So the question for an NSF-certified brass supplier in India is not whether the company says it is certified. It is whether your exact fitting is listed, under whose name, and for which factory.
What NSF 61 covers
ANSI/NSF/CAN 61 is a health-effects standard for components that touch drinking water, such as fittings, valves and pipes. Products are tested for substances that can leach into the water. Brass fittings are often also tested for lead content under the related NSF 372 standard, which supports the lead-free requirements of US law.
Certification is issued by accredited bodies, for example NSF, UL, IAPMO or WQA. The certificate lists the product and the manufacturing location. Many US states and plumbing codes require it, so check with your customer and the local authority which approval your market requires.
What WRAS approval covers
WRAS, the Water Regulations Advisory Scheme, tests fittings against UK water requirements, including whether materials affect water quality. Approved products are listed in a public directory. In England and Wales, the Water Fittings Regulations require fittings to comply, and WRAS approval is a common way to show it.
WRAS approval is held by a named product and applicant. A listing for a similar-looking fitting does not cover yours. Confirm the current rules with WRAS or your local water supplier.
Who must hold the approval?
The approval holder is the company that applied, normally the manufacturer or the brand owner. A distributor may be able to sell an approved product, but it cannot claim approval for a product it did not have tested.
If you import an unbranded fitting from an Indian factory and sell it as NSF 61, you need either the factory's certificate to cover that part, or your own application. Ask who will apply, who pays for testing and who owns the listing. We cannot promise that a given fitting will pass, because that depends on the alloy, the finish and the test body.
How to check what a supplier shows you
Do not rely on a PDF alone. Look the company and product up on the certifier's online database, and compare the part number, material and factory address with what you are buying.
The alloy matters. Standard free-cutting brass contains lead, so potable-water fittings use lead-free or low-lead brass. See what lead-free brass is and when it is required. In regions with aggressive water, buyers also ask for dezincification-resistant material, as covered in DZR brass.
