Bangladesh: Bangladesh is a Lower Developing Country with GSP facilitiy. Buyers import various types of garments from Bangladesh. The Generalized System of Preferences (known as GSP for short) is a scheme whereby a wide range of industrial and agricultural products originating in certain developing countries are given preferential access to the markets of the European Union. Preferential treatment is given in the form of reduced or zero rates of customs duties. The GSP scheme is specifically designed to benefit certain developing countries and integrate them into the world economy. Since 1971, the EU has had rules ensuring that exporters from developing countries pay lower duties on some or all of what they sell to the EU. This gives them vital access to EU markets contributing to the growth of their economies. This scheme is known as the "Generalized System of Preferences". Today Bangladesh offers a very flexible and feasible production base for its customers in EU, America and Australia. The EU market is quota free for apparels and goods are eligible for the GSP facilities. As an LDC member Bangladesh also obtain special Tariff benefit from Canada (18% import Tax free). FOB: FOB means Free on Board. It is the value of the product which is fixed without cost of transportation of this product. 6
CIF: FOB means Free on Board. It is the value of the product which is fixed including the cost of transportation and insurance of this product. Steps of garments export are described as follows: 1.Space Availability: Space availability or time agreement is the availability of availability of production floor for the production of garments. 2.Costing: Costing means the way of calculating the cost of production of garments. Costing is done considering- i) Fabric price ii) Accessories price & iii) C&M Cost Way of Costing: Costing can be done by- i) ii) Original Sample Specification Specification contains the following factors:- i) ii) Design or Sketch of garments Fabric Type- - Composition 7
- - - - Color Construction GSM or Ozs. Per Square Yards. Any other instruction iii) iv) v) Accessories Detail Any Kind of Instruction Garments Size ( called “Measurement Chart” or “Size Chart” ) Specification File: The file which contain the specification of product is called the “Specification File” or “Technical Package” or Tech-pack” or “PDM” (Product Development Manual) or “Order Sheet” or “Product Package”. Specification File is issued by the buyer and collected by the manufacturer. BOM Sheet: The pages of specification file contain fabric and accessories detail is called BOM ( Bill of Material ) Sheet. 3.Order Confirmation: Order confirmation is issued by the buyer to the manufacturer which contains Tech- pack. 4.Purchase Order: PO or purchase order is issued by the buyer to the manufacturer. 5.Master L/C: L/C or Letter of Credit is a confirmation which is prepared by the buyer ( bank of buyer ) and issued to the manufacturer.

Master L/C Back to Back L/C Master L/C is prepared by the buyer to import goods from the manufacturer. Back to Back L/C is prepared by the manufacturer to collect raw materials for the production. This L/C is issued by the manufacturer to the raw material suppliers. It depends on master L/C Prepared to collect raw material from the supplier. It has lower financial value than the Master L/C ( 70-80% of Master L/C ). This L/C is issued by the buyer to the manufacturer. It is the basic L/C. Prepared for the import of goods from the exporter. It has higher financial value than the Back to Back L/C. 9.Sampling: Sample is the small quantity which represents the bulk.

Types of Sewing thread being used in the garments industry of Bangladesh- 1. Polyester Core spun Thread. 2. Spun Polyester Thread. 3. Staple Spun Cotton Thread. 4. Textured Polyester Thread. 5. Polyester Cotton Core spun Thread. 6. Trilobal Polyester Thread. 1.Polyester Corespun Thread: This is more costly thread. This type of thread is produced by spinning staple polyester fibre around a core of high tenacity continuous filament polyester in yarn- spinning operation. Two or more of these composite yarns are then twisted together to give the necessary size and tensile strength. e.g. Epic(Coats). Staple polyester filament Core polyester filament Uses: Mainly used in topstitching of shirts, blouses, trousers, sportswear, jeans & work clothes etc. 39
Advantages: o Exceptionally strong. o 3.Its resistance to abrasion helps ensure long seam life in a wide variety of materials. o Fine threads can be used for delicate fabric without compromising on strength, thereby avoiding problems like seam pucker 2. Spun Polyester Thread: Staple polyester fibres are spun into polyester yarn. Then two or more of spun polyester yarns are twisted together to produce spun polyester thread. e.g. Astra (Coats) Advantages: o 1.High tenacity of polyester ensures greater strength and thereby high abrasion resistance. o 2.Very least amount of shrinkage (less than 1%) compared to cotton thread. Uses: Mainly for over-edging. Also used for general seaming of shirts, trousers, knitwear, jackets, blouses etc 3. Staple Spun Cotton Thread: Normally long staple cotton fibres are spun into cotton yarn. Then two or more ply of spun cotton yarn are twisted together to produce spun cotton thread. e.g. dymax (Coats) 40
Advantages: 100% cotton thread have relatively low strength and elongation compared to those in synthetic thread , therefore they need relatively light sewing tension and high stitch densities. o B. Very high amount of shrinkage compared to synthetic thread. o Uses: Mainly used in sewing cotton garments that are to be post dyed. 4. Textured Polyester Thread: Made from textured continuous polyester filament. (Note- texturing means modification by applying crimp to thefilament) . e.g. Gramax (Coats).
