Quality Inspector (soap industry)

Hi, my name is Rodrigo Cuevas, I am 27 years old and I am an Industrial Engineer.

In this occasion I will tell you about my experience as a Quality Inspector in a company that manufactures soaps for body use and clothing. I joined this company with the position of Quality Inspector and I was there for 1 year.

The activities that I carried out were;

• Reception of raw materials (supplies, packaging, aromas, labels)
• Review critical control points
• Reject material when does not meet with the specifications
• Ensure compliance of GMP’s
• Daily reports
• Validate machines parameters
• Validate color, odor, weight and packaging during the process
• Sampling and release of finished product

Soap is a product that is used directly on the skin, so we have to be careful, since if a foreign object falls into the soap it could hurt customers. The necessary precautions must also be taken, since working with chemical products can cause burns to the skin, masks, gloves, safety glasses and boots must be used.

There we work together with the Analysts, we support with them to validate the chemical parameters, consistency, color, odor, pH, saponification, humidity, etc.

We also make edible oil at that company, I’ll talk to you about that next time.


The manufacturing of hammocks is an art that is transmitted from generation to generation and It has been kept for centuries in Mexico.

The hammocks are hand-woven by Mexican artisans, who use cotton, nylon, and crochet thread, they are very comfortable and spacious, as well as not fading from the sun, so they are ideal for outdoors and indoors.

To talk about Mexican hammocks is talk about products of great pragmatic value, capable of offering a great rest, but also of providing style and sophistication to a home. Mexican hammocks and especially Yucatecan hammocks are excellent for their quality and durability.

The perfect accessories for hammocks are;

  • a good blanket
  • a cold drink
  • your favorite book

They can also be made with the most striking colors to the coldest, several or just one colors, they are ideal for a baby or even for a family.

In southern Mexico the weather is warm most of the year, the hammock is used daily instead of the bed, since the fabric lets air through, being the best solution against the heat.

In Mexico, they are made in states such as: Yucatán, Oaxaca, Guerrero and Campeche, and are exported to North, Central and South America, as well to Asia, Europe and Oceania.

Swinging in a hammock, hanging between two trees or in your favorite corner of the house, is the most relaxed way to rest from the hustle and bustle that the “stress” of the day imposes on us.

Quality Technician

Hello, my name is Rodrigo Cuevas, I am 26 years old and I am an Industrial Engineer. In this occasion, I will tell you about my experience as a Quality Technician in an electronics company.

I started as an intern in the quality area and 6 months later they promoted me to the position of Technician. In that position I lasted 2 years and we produced the motherboards to make smart offices.

The activities that I carried out were;

  • Monitor the FPY
  • Validate machines parameters
  • Audits
  • Work together with the other departments
  • Stop production lines when we find a defect
  • Weekly reports
  • Lead purges
  • Create alerts and special instructions
  • Visual aids
  • Train staff
  • Comply with the 5’s

I was in charge of 3 people with the position of Quality Support, with them we made sure that the product we manufactured was within the acceptance criteria according to the electronics manual IPC-610 rev F and the customer’s specifications, settle product quality above all else.

All processes had to be validated by us during the first piece, like cut, paste printing, component placement, welding, through hole, glue placement, retouch, rivet, etc., production did not start until our department was ensured that the first piece and the process are in accordance with the established.

Talavera: Breathtaking Art

You might have come across eye-catching Talavera objects with astonishing designs but do you know exactly what makes them so special? The most obvious answer is the impressive art decorations but the process behind these pieces requires knowledge that has been passed through generations.

Pottery Houses

One of the oldest pottery houses is located in the city of Puebla and was established in 1824. Uriarte Talavera is the largest Talavera manufacturer in Latin America whose art can be found in different regions around the globe. Every piece sold by them has gone through a long process of elaboration and is completely unique.


What makes this form of art so unique is that the elaboration process is based on knowledge passed from generation to generation recorded in particular communities that consider ‘Talavera’ to be part of their heritage and identity. As a result, this form of art is hard to copy. It requires knowledge and experience that machines or factories lack, ultimately making it a product at a low risk of being displaced.

Elaboration Process

  1. Clay Preparation: A combination of black and white clay is made.
  2. Molding: Potters shape the pieces. They’re careful during the drying process to make sure that it’s even and all pieces are the same.
  3. Baking: After drying the pieces, they are baked at 1,200 degrees Celsius for 10 hours. 
  4. Enamel: Pieces are left to dry for 24 to 48 hours; When they begin to turn white, the enamel is put by hand with a mule hair brush.
  5. Stencil: This is a technique used to decorate surfaces that consists of stamping a pattern using a thin sheet of cardboard, plastic, or metal.
  6. Decoration: The final step can consist of using cobalt blue color to decorate without following patterns and the colored decoration that uses pre-established patterns.

Blown glass

Blown Glass is the artisan process of making beautiful glass objects by creating “bubbles” in molten glass.

The Process

To create these precious colorful objects such as spheres, vases, flagon, glasses, plates, chandeliers, goblets or decorative items, Mexican artisans blow air through a long metal tube to make “bubbles”, and with the help of tools, these pieces acquire a shape. For this beautiful art, artisans need very strong lungs and they’re able to mold the pieces into desired shapes with bounces, combining short and long puffs, with the rotation of the metal tube, and controlling the temperature.

This is truly an art where Mexican artisans are the protagonists throughout the production process, and they ensures to keep high quality and cosmetic details on every piece


The blown glass technique adopted an ecological slant since many artisans and manufacturers use recycled materials, this type of material comes from different container in disuse or discarded, after the bottle ended its useful life, for example; bottles or glassware in general, the material is collected from the places of consumption, crushed and then melted as if it were new material.


This form of art started in the state of Puebla in the 16th century, but throughout the years, it expanded to various places in Mexico, and now you can find this art in Baja California Sur, Jalisco, Puebla, CDMX, and Monterrey. It is a tradition that is kept alive in Mexican workshops, the pieces come to life thanks to the imagination and the skills of the artisan, and become unique pieces.

My Experience in the Quality Department

My name is Rodrigo Cuevas, I’m 26 years old, live in the state of Guadalajara, Jalisco and I’m an Industrial Engineer that graduated from the University of Guadalajara 5 years ago. During the last few years, I have worked for some companies in the quality department and have had two years of experience in the electronics industry, one year in the food industry (oil and soap), and have been working with a company for two years that provides third-party quality control services. On this occasion, I will share about my work experience in electronics.


I started working in an electronics company as an Intern for a period of 6 months, where we manufactured hard disk chassis for a telecommunications firm. In that project, we only handled the final assembly. The project involved:

  • Receiving all the parts that made up the frame (hard drives, cabinets, doors, rails),  
  • In the case of hard drives, we made sure that they were updated.
    • Necessary tests were carried out.
    • Verified that the serial numbers coincided with the established one.
    • Made sure that the parts had no defects such as bumps, scratches, detached labels, broken parts, etc.
    • In the case of finding a defective part, we rejected it and all the pieces had to be inspected.
    • We notified the supplier so that he was aware of the situation and took the necessary action before more similar parts arrived.

Basically I made sure that the product met all the customer’s requirements, both cosmetically and functionally, since we were the last filter in the process. Once we packed it, the pieces went directly to the customer.

The activities that I carried out there were the following: made weekly reports (DPPM, RTV), participated in MRB meetings, assigned a category to the defective material, worked together with all the departments, gemba walks (observe workstations for improvements), lead purges, verified that the supplier’s specifications were the same as requested by the customer.

In my opinion, the electronics industry is challenging, every day you can discover a new problem, and I’ll be sharing some more about my experience soon. 


Have you ever seen or come across beautifully designed pottery like the one shown in the image? This decorative style is known as Talavera and can be found in the Mexican state of Puebla. The technique is so unique that in 2019, UNESCO declared the “Manufacturing Process of Talavera Ceramics” as Intangible Cultural Heritage of Humanity. I’ve been fortunate enough to travel to Puebla recently and came across local artisans along the roads that are experts in Talavera, who taught me some interesting information about it.


According to the locals, Talavera is an ancient technique that was discovered in the year 850 A.C in some Arab countries such as Iraq and from there it spread all the way from India to Spain. It ultimately reached the state of Puebla with the arrival of the Spanish conquistadors who not only used it for pottery because of its high-quality, but also used it for religious ceremonies, funerals and extraordinary sculptures.


The technical definition of the Talavera technique, registered under INDAUTOR, is “Typical pottery from the Puebla area, made with clay and made up of a ceramic body covered with tin glaze, decorated with metallic colors and worked manually on site”. In all honesty, this definition is simple compared to what the entire process truly entails. Artisans go through a number of steps in order to be able to finally decorate the ceramics. This long process is all worth it because at the end, you have a high-quality, beautifully decorated product that won’t break easily and will resist extremely high temperatures. 

The 3 Basic Documents You Need for Importing and Exporting

When searching for the required documentation to import or export you will encounter a bewildering array of documents to be considered. Here we selected the three most important you need to draw your attention towards.

Like it or not, for every single transaction in business a documentation is necessary. When you incorrectly prepare a document, it can create a huge hassle for all parties involved, regardless if it is in selling or purchasing something. When you are shipping a product (importing or exporting), it isn’t different. Goods cannot enter or leave a country unless accompanied by the required documents. And here you might keep your eye widely opened, because if your paperwork is incomplete, you can neither hand over nor collect your cargo. On the basis of the divergence, you may end up paying a penalty, which can cause you a misadventure to your reliability.

Sifting through here and there you may have found some documents which are related to importing and exporting, such as Proforma Invoice, Commercial Invoice, Packing List, Certificate of Origin, Certificate of Manufacture, Dock Receipts etc. Even though all these documents have their importance, there are three of them which are the key for your shipping process, and here we will take you through them.

Basic Documents Required for Exports

1. Bill of Lading

It is by far the most important document in the shipping process for both export and import. Providing evidence or proof of shipment, it indicates the owner of the cargo. Also, the bill of lading is an evidence of Contract of Carriage, receipt of goods and document of title to the goods. It is a legal document that contains all the details pertaining to the cargo being shipped, the destination, the terms of sale, and the details of the recipient. It must be signed by the appointed signatory of the shipping line, the exporter, and the importer. For smooth transportation of goods from one place to another, it is necessary that the exporter obtain a correct and complete bill of lading from the shipping line/forwarder. He must then send the bill of lading to the importer. The importer can collect the cargo only after he presents the bill of lading to the shipping line at the destination port. To learn more, read our well-explained article on the Bill of Lading.

2. Commercial Invoice-cum-Packing List: 

The commercial invoice is the document which provides the details of the sales transaction containing important information regarding the cargo, such as name of exporter/seller and importer/buyer, the value and quantity of the goods sold. Now, the packing list contains the details of the goods that are being shipped. It should mention the correct description of the goods, quantity, weight (gross and net), number and type of packages, and marks and numbers, carrier name, export data, export license number, and letter of credit number. This information is necessary for the Customs to ascertain the value of the goods and to facilitate examination at the time of clearance.

We wrote two separated articles to help you these documents better. Here you can learn more about Commercial Invoice and Packing List.

3. Bill of Export

Also known as “shipping bill of export”, it is a document requirement by the customs authority. It provides the details of any benefit that the shipper has availed in terms of customs duty, export schemes of the government, credit obtained under DEPB. If the goods are re-export of previously imported goods, then such details are also mentioned in the bill.

Basic Documents Required for Imports

Bill of Lading & Commercial Invoice cum Packing List

Not different from the exporting procedure, the bill of lading and commercial invoice-cum-packing list are also required documents for imports. The consignee has to collect these documents from the seller/exporter. Apart from these two documents, importers also need to present a bill of entry to be able to collect their cargo at the destination port.

Bill of Entry

It is a declaration by a consignee/importer or his appointed agent. It provides details of the type of cargo, its value, and quantity. It is prepared in three copies. The Customs inspect and clear the goods based on the information provided in the bill of entry. To ensure that there is no malpractice regarding the value of the goods, the bill of entry is tallied with the sales invoice or insurance policy.

What Is the Certificate of Manufacture

Also called Certificate of Conformance or Certificate of Compliance, this is an important document widely used in trade transactions for certifying – by a competent authority – that the supplied product meets the required specifications.

The certificate of manufacture (also known as certificate of conformance or certicate of compliance) is a document which is issued by a producer or a manufacturer a product (good or commodity) ordered by a buyer has been completed. It is an authenticated document and certifies that the product ordered by the buyer has been completed and is being stored by the manufacturer, with all risk borne by the buyer. Putting it more simply, the manufacturer stores the product, nevertheless, is not responsible for anything that might happen to it after issuing the certificate. This record also informs the buyer regarding any modification made to the product after the initial manufacturing phase. The certificate of manufacture can just be authentic if the date of modification on it is the same with that of the master file.

Next Step

After this initial procedure, the manufacturer will transfer a drawback product to another recipient, and then file and deliver the certificate of that product to the consignee.

Information for Issuing a Certificate of Manufacture

For the issuance of a certificate of manufacture it is required to have some important information about the product and manufacturing procedure. The information presented on this list must be contained on the certificate and also on the delivery (which is normally executed by the producer or manufacturer):

  • Consignee’s name (owner of the drawback product)
  • In case the product is manufactured under a drawback ruling, it should feature the computer-generated number or code applied to it and also, the number seen on the letter of acknowledgement
  • The computer number or TD number of the product if manufactured under specific production drawback ruling
  • Types, numbers and the quality of the product in question
  • Import entry numbers, applicable duty amounts, and the HTSUS number up to the sixth digit for imported commodities
  • The date the factory got the merchandise
  • The date it was applied to production
  • The value of the merchandise at the factory
  • Market value of the waste, if the waste could be used for productions
  • Waste quantity
  • Information of the product and the number of outputs.

For articles it must also include:

  • The number of manufactured articles
  • Articles transfer number
  • The receiving recipients of the article

Minimum Information Requirements

The certificate of manufacture issued by a producer must be on company letterhead and present the following information:

  • Manufacture’s name
  • Product name
  • Lot number
  • ABG item number
  • Date of manufacture
  • Specification revision number
  • Specification effective date
  • Certification stating that no divergence was caused
  • Name of the QA/QC manager responsible for the certification
  • QA/QC manager’s signature who made certification
  • Signing date
  • Certificate of approval for importation

Certificate of Origin (CO) — When Can You Use It

Commonly used worldwide for facilitating trade and global commerce, millions of COs are being issued every single year around the globe, thus, becoming a document of great significance in international trade.

The Certificate of Origin (CO) is an important document in global trade. It is usually issued by the exporter and has the purpose of certifying that goods in a particular export shipment are utterly obtained, produced, manufactured or processed in a particular country. It confirms the genuine origin of the product and also serves as a declaration by the exporter to satisfy customs or trade requirements.       

The certificate of origin can be requested by customs, banks, or even stakeholders and importers. In most countries it is required for customs clearance procedures so that they can establish the duty that will be assessed on the goods, also, whether the goods may be legally imported at all.

CO for LC

The CO may be requested by the buyer in the documentary requirements stated within a letter of credit (LC). The LC may determine additional certifications or language within that must be noted in order for the certificate of origin to comply with the stated requirements.

Two Different Types of COs

Essentially, there exist just two types that can be issued by chambers:

1. Non-Preferential

Attests that the product is subject to no preferential treatment. This is the main type of CO that chambers can issue and are also known as “Normal CO”.

2. Preferential

Attests that the product is subject to reduced tariffs or exemptions when they are exported to countries extending these privileges. This CO is closely associated with Regional Trade Agreements.

Information for Issuing Your Certificate of Origin

In international trade there is no standardized certificate of origin (CO) form. As mentioned, it is normally issued by the exporter of goods. Generally speaking, it must contain at least the basic details about the shipped product, a tariff code (HS code), the exporter and importer’s data, and the country of origin.
Once the seller receives the information about the border control at the importing country (normally informed by the buyer’s customs broker), the seller will record these details, get the CO notarized by a chamber of commerce, and submit the form with the shipment. Detail requirements depend on the type of goods being exported and where they are going.

Eletronic Certificate of Origin

It is also possible to submit the required documentation online (with an eCO) and get an electronic certificate stamped by a chamber of commerce in less than a day or get an expedited paper certificate overnight. With an electronic certificate of origin.
