Product scopeDifferent building materials require different sourcing checks
A porcelain tile, aluminum profile, flooring panel, sanitary fixture, and door system should not be compared with the same questions.
05Tiles, stone, and surfaces
Ceramic tiles, porcelain tiles, slabs, countertops, wall panels, and decorative surfaces need dimensions, thickness, finish, color batch, breakage protection, and packing review. Treat tiles, stone, and surfaces as part of the controlled product specification. Record materials, dimensions, tolerances, variants, finish, labels, packaging, approved sample, and allowed substitutions, then route any change through written approval before production or a repeat order.
06Flooring and panels
SPC, laminate, engineered panels, wall boards, ceilings, and decorative sheets need material structure, wear layer, color matching, carton strength, and sample approval. Define flooring and panels before the check takes place: measurable requirement, sampling or test method, tolerance, critical and non-critical defects, evidence format, and pass, hold, or fail authority. The decision record should preserve the original finding instead of replacing it with a later correction.
07Doors, windows, and profiles
Doors, windows, aluminum profiles, frames, locks, handles, and fittings need drawings, measurements, finish, hardware, installation context, and packaging protection. Define doors, windows, and profiles before the check takes place: measurable requirement, sampling or test method, tolerance, critical and non-critical defects, evidence format, and pass, hold, or fail authority. The decision record should preserve the original finding instead of replacing it with a later correction.
08Sanitary ware and fixtures
Basins, faucets, shower hardware, drains, accessories, and project fixtures need finish consistency, functional checks, spare parts, labels, and shipping protection. The record for sanitary ware and fixtures identifies the destination rule, source and date checked, product configuration, responsible legal party, required label or document, and evidence status. Supplier statements can help collect information, but they do not replace current authority, laboratory, customs, tax, or legal review.
