Товар можна повернути, якщо тільки упаковка не має пошкоджень.

This is an impersonal construction:

можна + infinitive = it is possible / allowed to ...

So можна повернути means can be returned or it is possible to return.

Ukrainian often uses this structure for rules, instructions, and policies, where English might use a passive:

• Товар можна повернути = The item can be returned

There is no need to name a subject such as you. The sentence is about a general rule, not about one specific person.

Here товар is the direct object of повернути, so it is in the accusative case.

But for many masculine inanimate nouns, the accusative singular looks exactly the same as the nominative singular:

• nominative: товар
• accusative: товар

So the form does not visibly change.

Also, Ukrainian often uses singular товар in a general or commercial sense, where English might say goods or an item/product, depending on context.

This is a question of aspect.

• повернути = perfective: to return something successfully, as a completed action
• повертати = imperfective: to be returning / to return in general / repeatedly / as a process

In a return-policy sentence, повернути is natural because the focus is on the completed act of returning the item.

Compare:

• Товар можна повернути протягом 14 днів = the item can be returned within 14 days
• Товар можна повертати протягом 14 днів = more like items may be returned during that period, with a more general/process-like feel

Both can appear in real Ukrainian, but повернути fits this sentence very well.

No. In this sentence, якщо тільки means:

• only if
• provided that

It does not mean the emotional English expression if only = I wish...

So here the idea is:

• the item can be returned only if the packaging has no damage

For learners, it is useful to know that many speakers would also say:

• тільки якщо
• лише якщо

These are often clearer and more straightforward when you want to say only if.

Because якщо introduces a subordinate conditional clause.

Main clause:

• Товар можна повернути

Conditional clause:

• якщо тільки упаковка не має пошкоджень

In Ukrainian, subordinate clauses are normally separated by a comma, so the punctuation here is standard.

Because не має and немає are used differently.

1. не має

This is the normal negation of мати = to have:

• упаковка не має пошкоджень = the packaging does not have damage

Here упаковка is the subject.

2. немає

This usually means there is no / there are no It is used in an existential structure, not with упаковка as the subject:

• На упаковці немає пошкоджень = There is no damage on the packaging

So both are correct Ukrainian, but they are different sentence patterns.

Because after a negated verb like не має, Ukrainian very often uses the genitive.

So:

• має пошкодження = has damage / has a defect
• не має пошкоджень = has no damage / has no defects

Here пошкоджень is genitive plural.

The plural is also natural because it suggests no damage of any kind, no damaged spots, no defects, rather than one single specific mark.

This is one of those patterns that can feel unusual to English speakers, because English just uses damage without changing the noun form much.

Yes. A very natural alternative would be:

Товар можна повернути, тільки якщо упаковка не пошкоджена.

This version changes two things:

• якщо тільки → тільки якщо, which many learners find clearer
• не має пошкоджень → не пошкоджена, which means is not damaged

The original sentence is grammatical and understandable, but this alternative may sound a bit more direct in everyday usage.

Here упаковка is best understood as packaging.

That is why the sentence means that the product can be returned only if the packaging is undamaged.

Depending on context, упаковка can refer to:

• the packaging material
• the retail box
• the wrapped package as presented with the product

So in return-policy language, it often has the broad meaning original packaging.
