How to say "product" in Japanese

• 製品せいひんJLPT N3approx.Common
  nounThe everyday word for a product in the sense of manufactured or finished goods — something a company makes and sells. When you mean a commercial product, this is the word you want.
  この製品せいひんはイタリア製いたりあせいだ。↗

  This product is made in Italy.
• プロダクトCommon
  nounThe katakana loanword; it turns up chiefly in business and tech talk and otherwise overlaps with 製品. For an ordinary manufactured product, 製品 is the natural choice.
  このプロダクトはインテリジェント総合そうごう情報じょうほうシステムです。↗

  This product is an intelligent integrated information system.
• 積せきCommon
  nounStrictly the mathematical sense: the result of multiplying numbers. It has nothing to do with goods, so it is never the word for a commercial product.
• 産物さんぶつJLPT N1approx.Common
  nounSomething a place, activity, or process produces — the produce of the land or, figuratively, the product of someone's efforts or imagination. Not the word for a manufactured product.
  コーヒーはブラジルの主要しゅよう産物さんぶつである。↗

  Coffee is Brazil's main product.
• 物産ぶっさんCommon
  nounCollectively, the products or produce of a region or country — local goods viewed as a whole. It is a marginal match for a single 'product' and seldom the word you want.
  共立きょうりつ物産ぶっさんに、貴社きしゃにご助力じょりょくをお願ねがいするよう提案ていあんしました。↗
