Practical bottle condition checks

A visual and functional inspection can catch obvious damage and poor closures. It cannot certify material composition, conformity, impact strength or medical safety. Inspection is one layer inside a broader safety decision.

This page covers only the Inspect step. Before it, identify the product category and verify the applicable requirements; after it, decide whether the product fits the actual user and setting.

Product check

The useful checks

1
Body, rim and baseReject visible cracks, chips, sharp damaged edges, severe deformation or damage that prevents normal use or cleaning.
2
Closure and gasketCheck that threads engage cleanly, seals sit correctly and removable parts can be cleaned.
3
Leak testWhere appropriate and permitted, fill and close the bottle as instructed and check whether the assembled product leaks.
4
Material / specificationIf grade, coating, heat resistance or a specific material matters, rely on documented product specifications rather than appearance.
5
Manufacturer limitsCheck cleaning, temperature and replacement instructions. Do not assume all glass, plastic or steel bottles tolerate the same conditions.
6
Intended useA product suitable for a table may not suit a school bag, hot drink or heavy-use business programme.
Boundary

Do not turn a home test into unofficial certification

Tapping glass, squeezing plastic, judging weight or visually guessing steel grade can be shopper habits, but they are not substitutes for product specifications, applicable conformity evidence or formal testing. Use visible condition checks for what they can actually tell you.
Use-case judgment

Glass-specific checks

Look for chips, cracks and damaged rims; respect manufacturer thermal limits; remember that sleeves can reduce some impact but do not make glass unbreakable.

Use-case judgment

Steel-specific checks

Inspect rim, seams, interior finish, closure and gasket. If a specific steel grade or insulation performance matters, verify documentation or supplier specification rather than relying on appearance.

Scope check

Reusable-plastic checks

Inspect for damage or deformation and follow manufacturer use/replacement instructions. If the product falls within SLS 1616 scope, condition checking does not replace the applicable certification or import-inspection evidence.

Inspection catches condition problems — not every risk.
